RESUMEN

O objetivo desta revisão integrativa foi elaborar uma avaliação qualitativa da literatura existente sobre as modalidades de tratamento utilizadas para cistos dentígeros em pacientes pediátricos. O presente estudo trata-se de uma revisão integrativa da literatura na qual utilizou-se as bases de dados PubMed, BVS (Biblioteca Virtual em Saúde), LILACS, e SciELO. Como critérios de inclusão estavam os artigos publicados na íntegra, relatos de caso clínico, revisões sistemáticas e de meta-análise publicados nos últimos 10 anos, disponível nos idiomas português ou inglês, que abordassem a temática. Os critérios de exclusão foram: resumos, anais, editoriais, cartas ao editor, reflexão, duplicidade, artigos com detalhamento incompleto. O cisto dentígero é o tipo mais comum dos cistos odontogênicos de desenvolvimento e o segundo mais frequente entre todos que ocorrem nos maxilares, representando cerca de 20% de todos os cistos revestidos por epitélio nos ossos gnáticos. Clinicamente pode estar associado a qualquer dente impactado, porém ele envolve com mais frequência os terceiros molares inferiores. Acomete pacientes entre 10 a 30 anos de idade, com predileção pelo sexo masculino, sendo na maioria dos casos detectados em exames radiográficos de rotina. O tratamento baseia-se nas técnicas de descompressão, marsupialização e enucleação. O prognóstico para os cistos dentígeros é altamente favorável e não há chance de recorrência após a remoção completa. Assim, a decisão terapêutica deve ser tomada de forma adequada para cada caso, levando em consideração a localização anatômica, extensão clínica, tamanho, idade, remoção do dente não irrompido e possibilidades de acompanhamento.

The aim of this integrative review was to carry out a qualitative assessment of the existing literature on the treatment modalities used for dentigerous cysts in pediatric patients. This study is an integrative literature review using the PubMed, VHL (Virtual Health Library), LILACS and SciELO databases. The inclusion criteria were articles published in full, clinical case reports, systematic reviews and meta-analysis published in the last 10 years, available in Portuguese or English, which addressed the subject. The exclusion criteria were: abstracts, annals, editorials, letters to the editor, reflection, duplication, articles with incomplete details. The dentigerous cyst is the most common type of developmental odontogenic cyst and the second most frequent of all those that occur in the jaws, accounting for around 20% of all epithelium-lined cysts in the gnathic bones. Clinically, it can be associated with any impacted tooth, but it most often involves the lower third molars. It affects patients between 10 and 30 years of age, with a predilection for males, and in most cases it is detected during routine radiographic examinations. Treatment is based on decompression, marsupialization and enucleation. The prognosis for dentigerous cysts is highly favorable and there is no chance of recurrence after complete removal. Therefore, the therapeutic decision must be made appropriately for each case, taking into account the anatomical location, clinical extension, size, age, removal of the unerupted tooth and follow-up possibilities.

RESUMEN

OBJECTIVES: The purpose of the present study was to design and assess a 3D simulation model for submental flap surgery in training oral and maxillofacial surgery (OMFS) residents. METHODS: This quasi-experimental study involved a total of 20 OMFS residents attending and was conducted from September 2023 to December 2023. A 3D submental flap surgical phantom was designed using Mimics V.21 software and printed using fused deposition modeling technology. Participants were first tested on their knowledge of submental flap surgery before being randomly assigned to experimental or control groups. The experimental group received a lecture and demonstration using the developed phantom, while the control group had traditional lecture education only. Afterward, the same test was administered to all participants post-training. Pre- and post-test scores were calculated and compared between the two groups. p-Value < 0.05 was considered statistically significant. RESULTS: The average pre-intervention test scores in the control and experimental group, were 2.5 ± 1.43 and 3 ± 0.816, respectively (p = 0.35). Post-intervention, the experimental group exhibited significantly higher exam scores compared to the group who had only received academic lecture training (6.9 ± 0.87 vs. 4.9 ± 0.99) (p < 0.001). Irrespective of the applied teaching method, both groups showed a significant increase in exam scores after receiving submental flap training (p < 0.001 for both groups, paired-sample t-test). CONCLUSION: The use of the developed submental flap phantom model significantly improved OMFS residents' test scores and knowledge of the surgical technique, suggesting its potential integration into the conventional resident training curriculum.

RESUMEN

Tooth extraction or extraction is a common procedure in dental practice, although it is a common practice, it is not exempt from complications. Paraesthesia is defined as a neuropathy with altered sensations and permanent anesthesia. The case of two patients who attended the Department of Pathology at the Faculty of Dentistry with paresthesia is reported. Both were treated with low-power laser therapy, showing a significant improvement in their clinical condition. The application of low-power laser presents ideal benefits in various areas of the stomatological field. As it is a non-invasive, painless treatment and short sessions, the patient is encouraged to continue with the treatment until they are almost completely rehabilitated.

RESUMEN

OBJECTIVES: Tooth extraction is one of the most frequently performed medical procedures. The indication is based on the combination of clinical and radiological examination and individual patient parameters and should be made with great care. However, determining whether a tooth should be extracted is not always a straightforward decision. Moreover, visual and cognitive pitfalls in the analysis of radiographs may lead to incorrect decisions. Artificial intelligence (AI) could be used as a decision support tool to provide a score of tooth extractability. MATERIAL AND METHODS: Using 26,956 single teeth images from 1,184 panoramic radiographs (PANs), we trained a ResNet50 network to classify teeth as either extraction-worthy or preservable. For this purpose, teeth were cropped with different margins from PANs and annotated. The usefulness of the AI-based classification as well that of dentists was evaluated on a test dataset. In addition, the explainability of the best AI model was visualized via a class activation mapping using CAMERAS. RESULTS: The ROC-AUC for the best AI model to discriminate teeth worthy of preservation was 0.901 with 2% margin on dental images. In contrast, the average ROC-AUC for dentists was only 0.797. With a 19.1% tooth extractions prevalence, the AI model's PR-AUC was 0.749, while the dentist evaluation only reached 0.589. CONCLUSION: AI models outperform dentists/specialists in predicting tooth extraction based solely on X-ray images, while the AI performance improves with increasing contextual information. CLINICAL RELEVANCE: AI could help monitor at-risk teeth and reduce errors in indications for extractions.

RESUMEN

Paget disease is an intraepithelial neoplastic proliferation, commonly occurring in the breast and apocrine-rich areas, often associated with an underlying internal malignancy. Extramammary Paget disease (EMPD) of the oral cavity is exceedingly rare, with only eight reported cases, four of which were associated with an underlying internal malignancy. Here, we report a case of oral EMPD involving the buccal mucosa and gingiva of an 81-year-old male with no known underlying internal malignancy. The Paget cells were positive for CK7, CK20, CAM5.2, and androgen receptor, but negative for SOX10 and p63. The immunophenotype, association with internal malignancies, and treatment approaches for oral EMPD are reviewed.

RESUMEN

Introduction: Diabetes mellitus (DM) is a prevalent chronic metabolic disorder worldwide, with Type II DM (T2DM) emerging as the most widespread variant. In Chile, approximately 11% of adults aged 20 to 79 suffer from this condition. Given its high prevalence, dental surgeons should be trained to evaluate risk factors, particularly the potential complications linked to tooth extraction in individuals with T2DM. Objetive: To describe the available scientific evidence on post-exodontia complications associated with hyperglycemia in patients with Type II diabetes mellitus. Materials and Methods: An exploratory systematic review was conducted following the PRISMA-ScR extension protocols using the databases PubMed, EBSCO, Scopus and the Cochrane Library. The search employed the following algorithms: (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes" AND "tooth extraction")), (("Glycemia" AND "Tooth extraction complications"), (("Blood glucose" AND "Tooth extractions"), (("Dental extraction sockets" AND "Diabetics"). Results: Out of a total of 973 articles, 25 were included for this review. Six relevance criteria were considered, revealing safety parameters for conducting extractions in patients with T2DM, with capillary blood glucose levels not exceeding 200 mg/dL for elective extractions and 240 mg/dL for emergency extractions. Conclusions: There is limited evidence correlating threshold values of hyperglycemia with post-extraction complications in patients with T2DM. Most authors agree that the primary concern is not T2DM itself, but hyperglycemia. Furthermore, there is minimal consistency in the recommended care protocols for these patients.

Introducción: La diabetes mellitus (DM) es un trastorno metabólico crónico. A nivel mundial, la DM tipo II (DM2) resulta ser la más frecuente. En Chile, un 11% de la población adulta entre los 20 y 79 años la padece. Su alta prevalencia, requiere de un cirujano dentista preparado para valorar los factores de riesgo, como las posibles complicaciones asociadas a la extracción dental en estos pacientes. Objetivo: Describir la evidencia científica disponible sobre complicaciones post-exodoncia asociadas a hiperglicemia en pacientes con diabetes mellitus tipo II. Materiales y Métodos: Se realizó una revisión sistemática exploratoria bajo los protocolos de extensión PRISMA-ScR utilizando las bases de datos, PubMed, EBSCO, Scopus y Cochrane Library con los algoritmos de búsqueda (("Diabetic patient complications" AND "Dental extractions")), (("Diabetes"AND "Tooth extraction")), (("Glycemia" AND "tooth extraction complications")), (("Blood glucose" AND "Tooth extractions")), (("Dental extraction sockets"AND "Diabetics")). Resultado: De un total de 973 artículos se incluyeron 25 artículos para esta revisión. Se consideraron 6 criterios de pertinencia, los cuales mostraron parámetros de seguridad para realizar exodoncias, en pacientes con DM2, con la glucemia capilar no mayor a 200mg/dl en caso de ser electiva y 240 mg/dl en exodoncia de urgencias. Conclusión: Existe poca evidencia que correlacione valores absolutos de hiperglucemia y complicaciones post exodoncia en pacientes con DM2. La mayoría de los autores concuerda en que el problema no es la DM2, sino la hiperglucemia. Existe poca uniformidad en los protocolos de atención recomendados para estos pacientes.

RESUMEN

PURPOSE: To evaluate the accuracy of magnetic resonance imaging (MRI) for jawbone assessment compared to reference-standard measurements in the literature. MATERIALS AND METHODS: An electronic database search was conducted in PubMed, EMBASE, Scopus, Web of Science, and the Cochrane Library in June 2022, and updated in August 2023. Studies evaluating the accuracy of MRI for jawbone assessment compared with reference-standard measurements (histology, physical measurements, or computed tomography) were included. The outcome measures included bone histomorphometry and linear measurements. The risk of bias was assessed by the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2). The review was registered in the PROSPERO database (CRD42022342697). RESULTS: From 63 studies selected for full-text analysis, nine manuscripts were considered eligible for this review. The studies included assessments of 54 participants, 35 cadavers, and one phantom. A linear measurement error ranging from 0.03 to 3.11 mm was shown. The accuracy of bone histomorphometry varies among studies. Limitations of the evidence included heterogeneity of MRI protocols and the methodology of the included studies. CONCLUSION: Few studies have suggested the feasibility of MRI for jawbone assessment, as MRI provides comparable results to those of standard reference tests. However, further advancements and optimizations are needed to increase the applicability, validate the efficacy, and establish clinical utility of these methods.

RESUMEN

Conventional obturator prostheses might cause dissatisfaction in patients with hard or soft palate defects due to inadequate retention and function during speech, mastication, and swallowing. Thus, surgical reconstruction and implant-supported obturators are considered as alternative treatments for these patients. This case-report study describes the prosthetic reconstruction of an 88-year-old patient suffering from a hard palate defect after surgical resection of verrucous carcinoma in the left side of the hard palate. Fifteen months after radiotherapy, two implants were placed in the right side of the remaining ridge, in the second and third molar region. After the implant healing period, the implant-supported obturator prosthesis was fabricated. The patient was satisfied with the esthetics and function of the obturator at the 12-month recall visit and radiographs showed normal healing and no bone loss around the implants.

RESUMEN

BACKGROUND: Jaw osteoradionecrosis (ORN) is a complication in patients with previous head and neck radiotherapy. Its incidence increases with dental extractions. Hence, this review aimed to evaluate the efficacy of adjunctive treatment modalities undertaken at the time of extraction in previous head and neck radiotherapy patients in preventing ORN. METHODS: A systematic review was conducted, where studies with data on ORN incidence after extraction with or without adjunctive interventions were included. Meta-analyses were conducted to estimate the pooled prevalence of ORN per intervention and the pooled odds ratio for incidence of ORN between interventions. RESULTS: In total, 1520 patients in 29 studies were included. Interventions identified were hyperbaric oxygen (HBO), pentoxifylline-tocopherol (PENTO), antibiotics (ABX), platelet-rich fibrin and photobiomodulation. The pooled prevalence of ORN for HBO (4.6%), PENTO (3.4%) and ABX (3.8%) was significantly lower than the Control (17.6%). For studies with direct comparisons between groups, HBO had lower but not significant odds of developing ORN than the Control (OR 0.27) and ABX (OR 0.57). CONCLUSIONS: HBO, PENTO and ABX may reduce the incidence of ORN compared to no intervention. Given that all three have similar incidences of ORN, ABX may be the most cost-effective and accessible adjunctive modality.

RESUMEN

OBJECTIVE: This study aims to comprehensively analyze the global landscape of oral and maxillofacial surgery (OMFS) literature through bibliometrics. The research focuses on evaluating publication trends, influential topics, and the impact of scholarly works within the field. METHODS: Following the principles of the Leiden Manifesto, a literature search was conducted using the Web of Science database, encompassing seven OMFS journals. A total of 18,218 publications were analyzed, with indicators such as publication language, geographic location, specialty, year, citation, and authorship examined. Statistical analyses, including Pearson correlation tests and angular coefficient calculations, were performed in RStudio. RESULTS: The study revealed a strong upward trend in publications related to orthognathic surgery, trauma, and infections. Geographic analysis indicated a dominance of European and Asian contributions, with the USA leading in overall publications. The impact of self-citations was explored, emphasizing nuanced perspectives on their role in scholarly impact metrics. The data provided insights into the scholarly impact of OMFS publications, including the H-index, number of citations, and citing articles. CONCLUSION: The findings underscored potential global discrepancies in OMFS research, both geographically and in terms of topics covered. The study discussed the influence of language and journal impact on citation counts, emphasizing the role of English publications. Specific topics, such as trauma and infections, exhibited high scholarly interest and citation rates. Recommendations were made to encourage submissions on specific topics, such as cosmetic surgery and pathology, to enhance the diversity of OMFS literature. The study aims to foster international collaboration and leverage bibliometrics for evidence-based decision-making, educational strategies, and advancements in the dynamic field of oral and maxillofacial surgery.

RESUMEN

ABSTRACT BACKGROUND AND OBJECTIVES: The extraction of third molars can lead to undesired effects such as pain, trismus, and edema, necessitating preemptive therapy to alleviate these effects. For this purpose, an economic evaluation was conducted to analyze the cost-effectiveness of preemptive drugs used in the extraction of third molars. METHODS: Costs were obtained from a market survey. Effectiveness measures were limitation of interincisal distance and postoperative pain, obtained from randomized clinical trials in the literature. For both models, a Monte Carlo simulation generated a hypothetical cohort of a thousand individuals, considering a 5% variation in estimates. The evaluated therapies were dexamethasone 8 mg (DX8); methylprednisolone 40 mg (MP); diclofenac 50 mg associated with tramadol 50 mg (DCTR); and dexamethasone 4mg associated with tramadol 50 mg (DXTR). RESULTS: MP and DCTR therapies were dominated in all scenarios. For the reduction of postoperative pain, DXTR treatment showed the best cost-benefit, with a net monetary benefit (NMB) gain of 31.10% compared to the lowest-cost treatment (DX, R$ 1.76). Considering the reduction in limitation of interincisal distance, DXTR medication presented higher cost-benefit compared to DX8 (NMB gain = 18.25%), being a preferred option alongside DX8. CONCLUSION: In the extraction of third molars, preemptive administration of dexamethasone 4mg associated with tramadol 50mg is the preferred cost-effective option to reduce postoperative pain and limitation of interincisal distance after 48 hours.

RESUMO JUSTIFICATIVA E OBJETIVOS: A exodontia de terceiros molares pode acarretar efeitos indesejados, como dor, trismo e edema, sendo necessário ofertar uma terapia preemptiva para amenizá-los. Para tal, realizou-se uma avaliação econômica para analisar o custo-efetividade de fármacos preemptivos utilizados na exodontia de terceiros molares. MÉTODOS: Os custos foram obtidos a partir de uma pesquisa de mercado. As medidas de efetividade foram: limitação da distância interincisal e dor pós-operatória, sendo obtidas em ensaios clínicos randomizados da literatura. Para os dois modelos, uma simulação de Monte Carlo gerou uma coorte hipotética de mil indivíduos, considerando uma variação de 5% das estimativas. As terapias avaliadas foram: dexametasona 8 mg (DX8); metilprednisolona 40 mg (MP); diclofenaco 50 mg associado a tramadol 50 mg (DCTR); e dexametasona 4 mg associada a tramadol 50 mg (DXTR). RESULTADOS: As terapias com MP e DCTR foram dominadas em todos os cenários. Para redução da dor pós-operatória, o tratamento com DXTR apresentou o melhor custo-benefício, com ganho de benefício monetário líquido (NMB) de 31,10% comparado ao tratamento de menor custo (DX, R$ 1,76). Considerando a redução da limitação da distância interincisal, o fármaco DXTR apresentou maior custo-benefício em relação à DX8 (ganho de NMB = 18,25%), sendo uma opção de escolha junto a DX8. CONCLUSÃO: Na exodontia de terceiros molares, a administração preemptiva de dexametasona 4 mg associada com tramadol 50 mg é a opção de escolha, do ponto de vista de custo-efetividade, para reduzir a dor pós-operatória e limitação da distância interincisal após 48 horas.

RESUMEN

Objetivo: O objetivo deste trabalho foi apresentar uma série de casos de manutenção de dentes retidos associados ao cisto dentígero (CD), empregando-se a marsupialização ou descompressão cística. Métodos: Realizou-se um estudo epidemiológico transversal, fundamentado na análise retrospectiva e descritiva dos registros do Serviço de Estomatologia e Cirurgia Bucomaxilofacial do HMOB (Hospital Metropolitano Odilon Behrens) entre novembro de 2005 a novembro de 2020. Resultados: Os resultados mostraram doze pacientes que receberam a marsupialização como tratamento do CD. Os dentes mais envolvidos foram pré-molares e incisivos centrais superiores e o tempo médio de erupção foi de 13 meses, sendo que a maioria das erupções ocorreram de forma espontânea. Em todos os casos verificou-se erupção do dente associado e neoformação óssea na região do cisto. Não foram observadas recidivas. Conclusão:Assim, baseado no presente estudo e na literatura, a marsupialização ou descompressão cística mostrou-se uma alternativa terapêutica eficiente na abordagem de pacientes jovens portadores de CD, inclusive, com o aproveitamento do dente associado ao cisto em casos selecionados.

Aim: The objective of this study was to present a series of cases of maintenance of impacted teeth associated with dentiger cyst (DC), using marsupialization or cystic decompression. Methods:A cross-sectional epidemiological study was carried out, based on a retrospective and descriptive analysis of the records of the Stomatology and Oral and Maxillofacial Surgery Service of the HMOB (Hospital Metropolitano Odilon Behrens) between November 2005 and November 2020. Results: The results showed twelve patients who received marsupialization as a treatment for DC. The most involved teeth were premolars and upper central incisors and the mean eruption time was 13 months, with most eruptions occurring spontaneously. In all cases, there was eruption of the associated tooth and new bone formation in the region of the cyst. No recurrences were observed. Conclusion: Based on the present study and the literature, marsupialization or cystic decompression is an efficient therapeutic alternative in approaching young patients with DC, including the use of the tooth associated with the cyst in selected cases.

RESUMEN

A doença de Chagas é uma infecção parasitária sistêmica causada pelo protozoário Trypanosoma cruzi (T. cruzi), descoberta em 1909, pelo médico e pesquisador brasileiro, Carlos Chagas. O objetivo deste estudo é discutir sobre as manifestações clínicas da Doença de Chagas e suas importantes implicações na Odontologia. Este artigo é baseado em um estudo de revisão narrativa da literatura, de abordagem qualitativa. O levantamento dos artigos foi realizado na base de dados PubMed, LILACS e SciELO totalizando 13 estudos utilizados para o complemento da pesquisa. A Doença de Chagas é transmitida pelo contato com as fezes do inseto vetor, chamado de "barbeiro" no Brasil. Quando a célula, a qual o protozoário invadiu, se rompe, os novos microrganismos procuram novas células para habitar, percorrendo o sangue e a linfa, atingido o coração, tubo digestivo e plexos nervosos. Ao afetar o tecido coronariano, os microrganismos instalam-se nas células cardíacas, principalmente nos fagolissomos, além de afetar o sistema cardíaco, a doença de Chagas pode apresentar envolvimento de mais dois importantes sistemas do corpo humano: sistema estomatognático e digestivo. No atendimento a pacientes chagásicos, que apresentam comprometimento cardíaco, o Cirurgião-Dentista precisa realizar anamnese bem detalhada a fim de se conhecer mais sobre a condição sistêmica do mesmo, protocolos de redução de estresse são imprescindíveis considerando que o atendimento odontológico induz um quadro de ansiedade nos pacientes. O conhecimento prévio sobre a doença de chagas é mandatório para o Cirurgião-Dentista, visto que as manifestações bucais da doença podem impactar diretamente na qualidade de vida desses indivíduos.

Chagas disease is a systemic parasitic infection caused by the protozoan Trypanosoma cruzi (T. cruzi), discovered in 1909 by the Brazilian physician and researcher, Carlos Chagas. The aim of this study is to discuss the clinical manifestations of Chagas disease and its important implications in Dentistry. This article is based on a narrative review of the literature, with a qualitative approach. The survey of articles was carried out in the PubMed, LILACS and SciELO databases, totaling 13 studies used to complement the research. Chagas disease is transmitted by contact with the feces of the vector insect, called "kissing bug" in Brazil. When the cell, which the protozoan invaded, ruptures, the new microorganisms look for new cells to inhabit, traveling through the blood and lymph, reaching the heart, digestive tract and nervous plexuses. By affecting the coronary tissue, the microorganisms settle in the cardiac cells, mainly in the phagosomes. In addition to affecting the cardiac system, Chagas disease can involve two more important systems of the human body: the stomatognathic and digestive systems. When caring for chagasic patients who have cardiac involvement, the dentist needs to carry out a very detailed anamnesis in order to learn more about their systemic condition, stress reduction protocols are essential considering that dental care induces a picture of anxiety in patients. Prior knowledge about Chagas disease is mandatory for the dentist, since the oral manifestations of the disease can directly impact the quality of life of these individuals.

RESUMEN

Os medicamentos ditos naturais, denominados de fitoterápicos, são medicações que buscam atingir os resultados necessários das medicações ditas convencionais, porém sem os efeitos adversos decorrentes de alguns grupos medicamentosos. Em cirurgia Buco-Maxilo-Facial uma linha de pesquisa já consolidada e com importância significativa é o controle da dor e inflamação decorrentes dos procedimentos cirúrgicos Buco-Maxilo-Faciais. Um nutracêutico já descrito e pesquisado na literatura para substituir os anti-inflamatórios alopáticos e seus efeitos colaterais, principalmente os gastrointestinais e renais que são altamente indesejáveis, é a Bromelina. Ainda existe a necessidade de mais estudos relacionados a dose terapêuticas para diferentes tipos de cirurgia e outros nutracêuticos... (AU)

So-called natural medicines, called herbal medicines, are medications that seek to achieve the necessary results of so-called conventional medications, but without the adverse effects resulting from some drug groups. In Oral and Maxillofacial surgery, a line of research that is already consolidated and has significant importance is the control of pain and inflammation resulting from Oral and Maxillofacial surgical procedures. A nutraceutical already described and researched in the literature to replace allopathic anti-inflammatories and their side effects, mainly gastrointestinal and renal side effects, which are highly undesirable, is Bromelain.

RESUMEN

Objetivo: apresentar o relato de duas pacientes com agenesias dentárias em que cinco dentes autotransplantados foram utilizados como modalidade de tratamento. Além disso, objetiva-se mostrar questões sobre a técnica cirúrgica, suas indicações e previsibilidade. Relato de caso: Neste estudo, foram relatados 5 casos de autotransplante dentário em duas pacientes jovens, em que a equipe realizou os procedimentos e o acompanhamento clínico e radiográfico por 5 e 7 anos. Devido à alta sensibilidade da técnica, foram seguidos princípios previamente estabelecidos na literatura envolvendo o autotransplante dentário. Durante o período de acompanhamento, os dentes se mantiveram em posição e em função e as pacientes não apresentavam queixas associadas. Considerações finais: a técnica do autotransplante dentário, quando bem indicada e executada, é capaz de promover resultados bastante satisfatórios, sendo uma ótima alternativa reabilitadora, com taxas de sucesso elevadas e custos reduzidos. No entanto, critérios em relação aos sítios doadores e receptores e a habilidade do cirurgião devem ser levados em conta para o sucesso do técnica.

Objective: presenting the report of two patients with tooth agenesis in which five autotransplanted teeth were used as a treatment modality. Furthermore, the aim is to show questions about the surgical technique and its indications and predictability. Case report: In this study, 5 cases of dental autotransplantation were reported in two young patients, in which the team performed procedures and had clinical and radiographic follow-up for 5 and 7 years. Due to the high sensitivity of the technique, principles previously established in the literature involving dental autotransplantation were followed. During the follow-up period, the teeth remained in position and function and the patients had no associated complaints. Final considerations: the dental autotransplantation technique, when well indicated and executed, is capable of achieving very satisfactory results, being a great rehabilitative alternative, with high success rates and reduced costs. However, criteria regarding donor and receptor sites and the surgeon's skill must be taken into account for the success of the technique.

RESUMEN

Los quistes radiculares constituyen los quistes odontogénicos más comunes de la cavidad bucal. El objetivo de esta investigación es caracterizar un paciente con quiste odontogénico radicular mandibular. Se presenta un individuo masculino de 86 años, que fue atendido en el Servicio de Cirugía Maxilofacial del Hospital Provincial General Universitario «Mártires del 9 de abril», de Sagua la Grande, durante los años 2017-2018. Inicialmente, se le realizó el estudio clínico correspondiente (interrogatorio y examen físico), y se observó una evidente tumefacción y abombamiento cortical en relación a dientes residuales permanentes mandibulares; se asoció radiográficamente a una imagen radiolúcida ovoide extensa, que justificó la realización de biopsias incisionales en primer orden. Se siguió una conducta quirúrgica, con resección total de la lesión mediante enucleación, y se confirmó el diagnóstico de quiste odontogénico radicular mandibular a través del estudio histopatológico.

Radicular cysts are the most common odontogenic cysts in the oral cavity. The objective of this investigation is to characterize a patient with a mandibular radicular odontogenic cyst. We present an 86-year-old male individual who was treated in the maxillofacial surgery service at "Mártires del 9 de Abril" Provincial General University Hospital in Sagua la Grande from 2017 to 2018. Initially, a corresponding clinical study was performed (interrogation and physical examination), and an evident swelling and cortical bulging was observed in relation to mandibular permanent residual teeth; it was radiographically associated with an extensive ovoid radiolucent image, which justified the performance of first-order incisional biopsies. A surgical procedure was followed, with total resection of the lesion by means of enucleation, and the diagnosis of mandibular radicular odontogenic cyst was confirmed through the histopathological study.

En 1827 el médico James William Cusack describió una lesión tumoral expansiva con características clínicas similares al ameloblastoma. Para el 2017 la Organización Mundial de la Salud lo clasificó como un tumor odontogénico benigno de origen epitelial. En la actualidad hemos aceptado la teoría de su etiología asociada con una mutación en el biomarcador BRAF-V600E, donde se presentan claras heterogeneidades extra/intratumorales en el metabolismo de la tumorogénesis; la mutación en BRAF genera cambios en la regulación de la odontogénesis, en conjunto con el gen CDC73 presente en el cromosoma 1 q25-q32, lo que produce un cambio en la proteína parafibromina que inhibe la proliferación celular durante el crecimiento y la división celular, esto afecta en conjunto al gen p53 y su homólogo p63 presentes en el cromosoma 17, por lo que se tiene como resultado la expresión de quistes y tumores dentales como el ameloblastoma. La presente obra muestra el caso clínico de un paciente femenino de 11 años de edad con aumento de volumen en la región submandibular izquierda de 7 × 4 cm, con seis años de evolución; de tal manera que fue diagnosticado con ameloblastoma uniquístico y tratado de forma conservadora mediante enucleación, posteriormente fue valorada anualmente hasta que la paciente cumplió los 18 años de edad (AU)

In 1827, physician James William Cusack described an expansive tumor lesion with clinical characteristics similar to ameloblastoma. For 2017, the World Health Organization classified it as a benign odontogenic tumor of epithelial origin. Currently, we have accepted the theory of its etiology associated with a mutation in the BRAF-V600E biomarker, where there are clear extra/intratumoral heterogeneities in the metabolism of tumorigenesis; the BRAF mutation generates changes in the regulation of odontogenesis, together with the CDC73 gene present on chromosome 1 q25-q32, producing a change in the parafibromin protein that inhibits cell proliferation during cell growth and division, which together it affects the p53 gene and its p63 homolog is present on chromosome 17, resulting in the expression of dental cysts and tumors such as ameloblastoma. This work provides the clinical case of an 11-year-old patient with an increase in volume in the left submandibular region of 7 × 4 cm of 6 years of evolution. Being diagnosed as a unicistic ameloblastoma and treated conservatively by enucleation, it is subsequently evaluated annually until the patient reaches 18 years of age (AU)

RESUMEN

Introdução: A alta prevalência do uso de medicamentos na população brasileira pode interferir na prescrição odontológica. Objetivos: Identificar os medicamentos em uso por pacientes atendidos em uma clínica de cirurgia oral menor e estimar os riscos de interações medicamentosas (IM) potenciais com fármacos comumente prescritos em procedimentos cirúrgicos. Materiais e Métodos: Realizou-se um estudo piloto analítico e transversal, sendo incluídos 24 pacientes atendidos na Clínica de Cirurgia Oral da Faculdade de Odontologia de uma universidade pública brasileira. Os dados foram coletados por meio de um questionário exploratório. Todos os medicamentos foram classificados no sistema Anatomical Therapeutic Chemical (ATC). As IM potenciais foram analisadas no banco de dados do Drugs® após correlação entre os medicamentos em uso pelo paciente e os medicamentos comumente prescritos em cirurgia oral.Resultados: Observou-se prevalência de 66,7% (n= 16) no uso de pelo menos 1 medicamento dentre os pacientes atendidos na clínica de cirurgia oral, com média de 3,5 (±2,2) medicamentos, sendo a polifarmácia identificada em 16,6% pacientes (n= 4). A média de idade dos usuários de medicamentos foi de 52 (±16) anos e totalizou-se 56 medicamentos. Os fármacos mais prevalentes foram aqueles atuantes nos sistemas nervoso e cardiovascular. Quando simuladas as adições dos fármacos comumente prescritos em cirurgia oral (anti-inflamatórios, analgésicos e antimicrobianos) aos medicamentos em uso pelos 16 pacientes, identificou-se 75 IM potenciais diferentes, sendo 61 (81%) de gravidade moderada e 14 (19%) de gravidade alta. As IM potenciais mais frequentes foram de anti-hipertensivos com anti-inflamatórios, enquanto as de importância clínica grave envolveram fármacos de ação central e analgésicos opioides. Conclusão: Observou-se alta prevalência na utilização de medicamentos pelos pacientes atendidos na clínica de cirurgia oral, com importante risco de interações com medicamentos prescritos em procedimentos cirúrgicos.

Introduction: The high prevalence of drug use in the Brazilian population can interfere with dental prescriptions.Objective: To identify drugs being used by patients seen at a minor oral surgery clinic and to estimate the risks of potential drug interactions (DI) with drugs commonly prescribed in surgical procedures. Materials and Methods: An analytical and cross-sectional pilot study was carried out, including 24 patients treated at the Oral Surgery Clinic of the Dental School of a Brazilian Federal University. Data were collected through an exploratory questionnaire. All drugs were classified in the Anatomical Therapeutic Chemical (ATC) system. Potential DI were analyzed in the Drugs® database after correlation between the drugs used by the patient and the drugs commonly prescribed in oral surgery.Results: There was a prevalence of 66.7% (n= 16) in the use of at least 1 medication among patients seen at the oral surgery clinic, with a mean of 3.5 (±2.2) medications, with polypharmacy identified in 16.6% patients (n= 4). Mean age of medication users was 52 (±16) years, totaling 56 medications. The most prevalent drugs were those acting on the nervous and cardiovascular systems. When the additions of drugs commonly prescribed in oral surgery (anti-inflammatory drugs, analgesics and antimicrobials) to the drugs used by the 16 patients were simulated, 75 different potential DI were identified, 61 (81%) of moderate severity and 14 (19%) of high gravity. The most frequent potential DIs were antihypertensives with anti-inflammatory drugs, while those of serious clinical importance involved centrally acting drugs and opioid analgesics. Conclusion: There was a high prevalence of medication use by patients seen at the oral surgery clinic, with a significant risk of interactions with prescribed medications in surgical procedures.
