RESUMEN

Introduction: Acromegaly is a rare endocrine disorder, presenting with orofacial mani-festations during its early stages. Timely diagnosis is often not made as these symptoms overlap with other oral diseases. Objective: The objective of this case report is to describe an unusual detection of acromegaly in a dental setting and to provide a checklist for referral upon suspicion of acromegaly. Materials and Methods: This case report describes the orofacial presentation and management of a 44-year-old Chinese man, initially referred for periodontal management. He presented with Localised stage II Grade A periodontitis, class III malocclusion, mandibular prognathism, and large mandibular interproximal gaps. Results: A provisional diagnosis of acromegaly was made, and the patient was referred to the Department of Endocrinology. Conclusion: Dental practitioners can pick up patients with undetected acromegaly with early orofacial changes during routine dental visits according to a simple proposed checklist. (AU)

RESUMEN

This case report aims to describe a modified surgically assisted rapid palatal expansion technique to treat an asymmetrical posterior crossbite with no mandibular shift without causing an interincisal diastema. A clinical patient with an asymmetrical crossbite, large tooth-size-arch length, and Bolton discrepancy is used to illustrate the modified technique. Instead of traditional osteotomies, in this technique, the osteotomy is done between the maxillary right canine and lateral incisor (connecting the piriform aperture to the alveolar process) along with a unilateral LeFort I osteotomy. The expansion forces are produced by the activation of a conventional hyrax appliance. The skeletal unilateral crossbite was corrected without major changes to the opposite side and without causing an anesthetic diastema between the maxillary central incisors. A mandibular incisor extraction produced the space needed to treat the tooth size-arch length and corrected the Bolton discrepancy. This allowed a successful treatment of the problems initially presented by the patient.

RESUMEN

BACKGROUND: Mixed dentition determines an important period of occlusion development in childhood. OBJECTIVE: This study aimed to evaluate the aesthetic impact of the midline diastema cut-off point in mixed dentition. DESIGN: A cross-sectional study was performed with 257 children aged 8-10 years in late mixed dentition, with midline diastema of 1-5 mm and normal maxillary overjet. Orthodontic Aesthetic Subjective Impact Score determined the aesthetic impact of the midline diastema. Four quartiles of diastema measurements and impact scores were considered as cut-off points. Receiver Operating Characteristic curves were constructed, and the distances representing the distances to the ideal point were calculated. The Yuden index determined the efficiency of measuring the diastema to assess the aesthetic impact. The Kruskal-Wallis test compared the groups of participants classified according to the diastema cut-off by the sample quartile regarding the impact score. The analyses were performed with a significance level of 5%. RESULTS: There was no significant difference between the four groups of measurement quartiles of the diastema regarding the aesthetic impact (P > .05). CONCLUSIONS: The perception of dental aesthetics in mixed dentition children was not affected by the midline diastema, regardless of the cut-off point.

RESUMEN

Resumo Esse artigo descreve o tratamento de um diastema na região anterior da maxila utilizando uma abordagem multidisciplinar. Paciente do gênero feminino, 38 anos, procurou atendimento odontológico na Clínica Faculdade de Odontologia da Universidade Nove de Julho, com queixa estética devido ao diastema da linha média maxilar. Após exame clínico e tratamento periodontal, verificou-se a necessidade de alinhamento e nivelamento dos dentes anteriores. O excesso de papila gengival entre 11 e 21 foi submetido à exérese, e um aparelho ortodôntico fixo foi instalado em 12, 11, 21 e 22. Após três semanas, quando os dentes estavam posicionados em condições mais favoráveis, uma contenção Hawley foi adaptada para pequenas correções no sentido vestíbulo-lingual. Para a restauração dos dentes, foi feito um molde diagnóstico e enceramento para permitir a construção de uma matriz de silicone. Um compósito nano-híbrido e um micro-híbrido foram escolhidos e colocados seguindo a matriz de silicone ajustada ao lado palatino dos dentes. Após os procedimentos de acabamento e polimento, o resultado estético foi muito satisfatório tanto para o paciente quanto para a equipe odontológica. A relevância clínica desse caso indica que é possível treinar alunos de Graduação para alcançar o sucesso no tratamento de diastemas adversos da linha média em um curto período de tempo, com planejamento e interação entre diferentes especialidades odontológicas.

Abstract This manuscript described the treatment of anterior maxillary diastema using a multidisciplinary approach. A female patient, 38 years old, looked for dental treatment at the University Nove de Julho Dental School Clinic with an esthetic complaint due to maxillary midline diastema. After clinical examination and periodontal treatment, the necessity of alignment and leveling of the anterior teeth was verified. Excess of gingival papilla between 11 and 21 underwent exeresis and an orthodontic fixed appliance was installed in 12, 11, 21, and 22. After three weeks, when the teeth were positioned in a more favorable condition, a Hawley retainer was adapted for small corrections in buccolingual direction. For teeth restoration, a diagnostic cast and wax-up was made to allow the construction of a silicone matrix. A nanohybrid and a microhybrid composite were chosen and placed following the silicone matrix adjusted to the palatal side of the teeth. After finishing and polishing procedures, the esthetic result was very satisfactory for both the patient and the dental staff. The clinical relevance of this case indicates that it is possible to train undergraduate students to achieve success treating adverse midline diastema in a short period of time throw planning and interaction among different dental specialties (AU)

La presencia de los diastemas es una de las quejas estéticas más comunes entre los pacientes. La utilización de resinascompuestas es una buena opción estética y funcional para realizar restauraciones e implementar técnicasrestauradoras de forma mínimamente invasiva. La técnica de estratificación con resinas se introdujo en 1980 dando muy buenosresultadosenlaseleccióndecolor,perosiendoelprocedimientomáscomplejoyrequiriendograndeshabilidadestécnicasademás de un aumento de tiempo clínico. Los materiales de composite y técnicas restauradoras que ayudan al uso simplificado deprotocolos clínicos son muy procurados por los odontólogos para reducir el tiempo de trabajo en el sillón yminimizar la sensibilidad postoperatoria.

The presence of diastemas is one of the most common aesthetic complaints among patients. The use of composite resins is a good aesthetic and functional option to perform restorations and implement restorative techniques in a minimally invasive way. The resin layering technique was introduced in 1980, giving very good results in color selection, but being the most complex procedure and requiring great technical skills in addition to an increase in clinical time. Composite materials and restorative techniquesthat aid in the simplified use of clinical protocols are highly sought after by dentists to reduce chair time and minimize post-operative sensitivity. It is for these reasons, in addition to simplifying shade taking, that Tokuyama Dental developed Omnichroma resin which claims to have the ability to copy the color of the remaining tooth substrate shortly after light curing known as the "Chameleon Effect" using a single shade. The objective of this article is to describe in detail, through a clinical case report, the closure of diastemas with Tokuyama Dental's Omnichroma universal resin.

RESUMEN

ABSTRACT: Nowadays, maxillary midline diastema (MMD) can be treated with different multidisciplinary approaches. When restorative dentistry is needed, glass-matrix ceramic materials is one of the best choices, since they present good optical behavior and high survival rates in the anterior dentition. To obtain an adequate interphase, and color integration are one of the main restorative goals, and for that purpose, specific finishing and polishing procedures must be employed to avoid staining and ensure the restoration's color stability. In the case report presented in this article, a single lithium disilicate ceramic fragment was performed to close a MMD produced by the shape alteration of one of the maxillary central incisors. Also, the finishing and polishing procedure is discussed.

RESUMEN

The lip brake is a fold in the oral mucosa, originating in the upper lip and insertion in the alveolar mucosa. At birth, the labial frenum may be inserted in the palatal papilla. As the individual grows, he can migrate to a more upper region, featuring a normal lip curl. However, when it remains inserted in the papilla, it is a case of hypertrophic lip curl. When pathological, this structure can promote the formation of interincisal diastema, periodontal pocket, gingival retraction, aesthetic problems, difficulties in phonation and brushing. The objective of this article is to report a clinical case of upper lip frenectomy using the double clamping technique or Archer technique, performed at the Oral Minor Surgery clinic of the Dentistry School of the Federal Fluminense University, in a male patient, leucoderma, 23 years old, indicated by his orthodontist after recurrence of interincisal diastema. From the procedure performed, it can be concluded that the surgical intervention and the applied technique were effective in solving the reported clinical case.

RESUMEN

INTRODUCTION: This study aimed to investigate the esthetic impact of mandibular crowding and maxillary midline diastema in children in the mixed dentition. METHODS: The sample for this cross-sectional study comprised 785 children, aged 8-10 years, in the late mixed dentition. Mandibular crowding and maxillary midline diastema were evaluated clinically with the Dental Aesthetic Index. Mandibular crowding and maxillary midline diastema were evaluated to determine tooth size-arch length discrepancies. The sample was stratified as group 1, children without maxillary midline diastema or mandibular crowding (n = 177); group 2, children with maxillary midline diastema (n = 256); group 3, children with mandibular crowding (n = 208); and group 4, children with maxillary midline diastema and mandibular crowding (n = 144). The subjective esthetic impact was evaluated using the Orthodontic Aesthetic Subjective Impact Score. Descriptive and exploratory analyses of the data were performed. A generalized linear model was applied, adjusted for the possible confounding variables (age, gender, and race) with a significance level of 5% because the Orthodontic Aesthetic Subjective Impact Score did not meet the assumptions of analysis of variance. RESULTS: Children in groups 2 and 3 showed greater esthetic concern than group 1 (P <0.05). Children in groups 2 and 3 did not show a significant difference with children in group 4 (P >0.05). CONCLUSIONS: Children with mixed dentition with mandibular crowding or maxillary median diastema reported significantly more esthetic concern than children without these conditions.

RESUMEN

Objetivo: Verificar a prevalência de diastema em adolescentes, analisar fatores associados e investigar o impacto dessa má oclusão na autopercepção dos adolescentes em relação ao seu sorriso. Métodos:A amostra consistiu em 160 adolescentes. Tratou-se de um estudo transversal e quantitativo realizado em escolas privadas (A1) e públicas (A2), no período de agosto de 2020 à julho de 2021, na cidade de Parnaíba, Piauí. Inicialmente, aplicou-se um questionário epidemiológico. A seguir, o exame clínico foi realizado sob luz natural, em ambiente escolar. Os alunos que apresentaram diastema constituíram o grupo G1 e os que não apresentaram formaram o grupo G2. Nos alunos do G1 foram identificadas a localização e a medida do diastema e dos possíveis fatores associados e aplicado um segundo questionário sobre a auto avaliação estética do sorriso. Foram realizadas estatísticas descritivas, obtendo-se porcentagens, frequências e análises de associação com o teste qui-quadrado e comparações de média a partir do teste t. Resultados:Houve diferença significativa na distribuição de adolescentes quanto ao tipo de escola e presença de diastema, verificando-se maior prevalência na escola pública. Quanto ao gênero, não foi encontrada diferença estatisticamente significativa, assim como não houve associação entre o sorriso e a presença de diastema, pois a maioria não apresentava vergonha ao sorrir, estava satisfeita e julgava ter um sorriso agradável. Verificou-se, quanto aos fatores associados, uma distribuição significativa com maior prevalência de "discrepância de tamanho dentário". Conclusão: A presença de diastema teve como fator associado predominante, a discrepância de tamanho dentário. A maioria dos adolescentes afirmaram estar satisfeitos com o sorriso, apesar de não ser agradável, considerando desnecessário o tratamento.

Aim: To verify the prevalence of diastema in adolescents, analyze associated factors, and investigate the impact of this malocclusion on adolescents' self-perception of their smile. Methods:The sample consisted of 160 adolescents. This was a cross-sectional and quantitative study carried out in private (A1) and public (A2) schools, from August 2020 to July 2021, in the city of Parnaíba, Piauí, Brazil. Initially, an epidemiological questionnaire was applied. The clinical examination was then performed under natural light, in a school environment. Students who presented diastema formed the G1 group, and those who did not, formed the G2 group. In G1 students, the location and measurement of the diastema and possible associated factors were identified and a second questionnaire was applied on the self-assessment of the esthetic smile. Descriptive statistics were performed, obtaining percentages, frequencies, and association analysis using the chi-square test and mean comparisons using the t test. Results: There was a significant difference in the distribution of adolescents regarding the type of school and presence of diastema, with a higher prevalence in public schools. Regarding gender, no statistically significant difference was found. There was also no association between smiling and the presence of diastema, as most were not ashamed to smile, were satisfied, and thought they had a pleasant smile. Regarding the associated factors, there was a significant distribution with a higher prevalence of "tooth size discrepancy". Conclusion: The presence of diastema was predominantly associated with tooth size discrepancy. Most adolescents said they were satisfied with the smile, despite not being pleasant, considering the treatment unnecessary.

RESUMEN

BACKGROUND: There is a controversy in the literature concerning the indications for frenectomy to treat interincisal diastema. Aims and Objectives: The aim of this study was to evaluate the spontaneous closure of the interincisal diastema in patients submitted to upper labial frenectomy (ULF) during the mixed dentition. MATERIALS AND METHODS: Records from patients treated between 2009 and 2014 in the course of Pediatric Dentistry Surgery at Fundecto-USP were evaluated to select those that were submitted to ULF during the mixed dentition using the Chelotti technique. Initial clinic characteristics and radiographic data related to the abnormal upper labial frenum were collected. The patients were called for a return visit to evaluate the diastema closure. The prevalence of children with diastema reduction after the frenectomy was determined by descriptive analysis. Logistic regression was used to evaluate the association between exposure factors and diastema reduction. Results: From 449 eligible records, 53 were selected and 25 were in a return visit. It was not possible to find association between the exposure factors and diastema closure. CONCLUSION: There is no relation between the time of surgery intervention and diastema closure. However, the intervention during the mixed dentition led to a partial diastema reduction in 80% of the cases.

RESUMEN

A doença periodontal é uma afecção comum, relacionada ao aprisionamento de alimentos em diastemas não fisiológicos, em equinos. O tratamento consiste na correção da causa primária, limpeza e desbridamento do sulco gengival, denominado tratamento convencional (TC). Frequentemente antimicrobianos são necessários, pela gravidade ou patogenicidade dos agentes. A terapia fotodinâmica adjuvante (TF) tem sido estudada pelo seu potencial combate bacteriano, sem causar resistência bacteriana. O objetivo deste estudo foi analisar o uso da TF na doença periodontal, experimentalmente induzida, em dentes incisivos de equinos, e compará-la com o TC. O TC não resultou em melhora clínica estatisticamente, tanto em graus como em profundidade, apenas numérica na profundidade aos 30 dias. A TF foi empregada em dentes com profundidade maior da bolsa periodontal que a do grupo TC e, mesmo assim, apresentou melhora clínica já com sete dias, e mais efetiva aos 30, atingindo, em média, o valor considerado normal, três milímetros. A TF apresentou potencial para ser aplicada na rotina, pelo incremento nos resultados, sem causar efeitos colaterais.(AU)

Periodontal disease is a common condition, related to the entrapment of food in non-physiological diastemas in horses. Treatment consists of correction of the primary cause, cleansing and debridement of the gingival sulcus, called Conventional Therapy (CT). Often antimicrobials are requested due to the severity or pathogenicity of the agents. Adjuvant Photodynamic Therapy (PDT), has been studied for its potential bacterial combat, without causing bacterial resistance. The objective of this study was to analyze the use PDT with the experimentally induced periodontal disease in the incisor teeth of horses, and to compare with the CT. The CT did not result in clinical improvement, either in degrees or millimeters. The PDT was used in teeth with a greater depth of the periodontal pocket than the TC group, and even then, showed clinical improvement in only seven days, and more effective at 30, reaching the three millimeter value considered normal on average. The PDT presented the potential to be applied in the routine by the increase in the results without causing side effects.(AU)

RESUMEN

Atualmente é constante a demanda por sorrisos harmoniosos nos procedimentos clínicos odontológicos, resultando em estímulos no desenvolvimento de técnicas minimamente invasivas, sistemas adesivos e materiais que sejam capazes de reproduzir as características naturais dos elementos dentários. Para as reabilitações estéticas, em especial nas unidades anteriores, os laminados cerâmicos apresentam destaque, em virtude das suas características físicas e ópticas. Como procedimento alternativo, as facetas pré-fabricadas em resina composta foram reintroduzidas na Odontologia Restauradora, exibindo versatilidade, facilidade e relação custo/benefício satisfatórias. Objetivo: Relatar um caso, demostrando uma das opções viáveis para solucionar problemas estéticos, como diastemas e desproporções dentárias. Relato de caso: A paciente procurou atendimento odontológico especializado relatando insatisfação com o sorriso. Durante avaliação, foram observados desarmonia nas proporções dentárias, diastemas múltiplos, restaurações deficientes em resina composta e fraturas nas bordas incisais. Diante disso, após o registro fotográfico, foi realizado a seleção do formato e cor das facetas pré-fabricadas, assim como, do agente de cimentação. A seguir, foi feito o isolamento relativo, remoção das restaurações deficientes e os ajustes das facetas ao dente. Para preparação da peça, foi realizado a limpeza e aplicação do adesivo; nos preparos dentários, após asperização da superfície, houve o condicionamento e aplicação do adesivo, a seguir procedeu-se a etapa de cimentação e, acabamento e polimento. Conclusão: O tratamento realizado conseguiu suprir as necessidades estéticas do sorriso da paciente, mostrando que as facetas préfabricadas em resina composta apresentam estética satisfatória, facilidade de instalação, baixo custo em relação as peças em cerâmica e conservação da estrutura dentária(AU)

Introduction: In present days, there is a constant demand for harmonious smiles in the dental clinical procedure, resulting in encouragement on development in minimally invasive techniques, adhesives systems and materials that can be capable to reproduce natural dental elements. For aesthetic rehabilitation in special in the anterior units, the ceramic laminates are highlighted due to their optical and physical features. As an alternative procedure, prefabricated composite resigns have been reintroduced into restorative dentistry, showing satisfactory versatility, ease and cost-effectiveness. Objective: Report a case, showing one of the viable options to solve aesthetical problems as diastemas and dental disproportions. Case Report: The patient sought specialized dental care reporting dissatisfaction with the smile. During evaluation, disharmony in tooth proportions, multiple diastemas, composite deficient resigns restorations and incisal edges fractures were observed. Therefore, after the photographic register, the shape and colour of the prefabricated facets, as well as cementing agent were selected. Hereinafter, relative isolation, removal of the deficient restorations and adjustments of tooth's veneers were then performed. For the piece preparation, cleaning and adhesive application were performed; on dental preparations, after the surface roughening, the adhesive was etched and applied followed by finishing and polishing cementation. Conclusion: The treatment was able to supply the aesthetical needs of the patient's smile, showing that prefabricated composite resigns veneers present satisfactory aesthetics, ease installation, low cost compared to ceramic pieces and conservation of the dental structure(AU)

RESUMEN

OBJECTIVE: This study aimed to use eye tracking to analyse people's visual perceptions of smiles with a diastema between the maxillary central and lateral incisors, based on different categories of observers. SETTING AND SAMPLE POPULATIONS: An image of a diastema between the maxillary central and lateral incisors was shown to dental students and laypeople. MATERIALS AND METHODS: Our null hypothesis was that there would be no difference in the visual perception of the different graduations of diastemas between the two groups. The diastemas were edited in Photoshop® to gradually increase the distance between the maxillary central and lateral incisors from no diastema to 1.5 mm and 3.5 mm diastemas. These diastemas were evaluated by using a TheEyeTribe© tracker in conjunction with OGAMA© 5.0 software. A total of 37 dental students and 33 laypeople looked at eight randomly arranged images of smiles. The data were analyzed using color coded maps, scanpaths, and the Kruskal-Wallis test with a level of significance of 5%. RESULTS: Laypeople tended to observe the eyes, focusing more on the right than the left, and spent less time focusing on the diastema region than did the dental students. There were differences for the same magnitude of diastema within participant groups. As the width of the diastema increased, both students and laypeople focused more on the diastema region. CONCLUSIONS: The two groups of evaluators presented different perceptions of smiles in cases of diastema between the maxillary central and lateral incisors when evaluated using eye-tracking.

RESUMEN

A presença do ponto de contato é essencial para manter a saúde das estruturas periodontais, além de evitar inclinações dentárias e desgastes, conservando, assim, uma oclusão ideal. Objetivo: apresentar um relato de caso clínico com restabelecimento dos pontos de contato de forma conservadora, por meio da ortodontia e da dentística restauradora, em dentes com coroas totais. Relato de caso: paciente do gênero feminino, 69 anos de idade, compareceu à clínica odontológica da universidade com queixa de impacção alimentar e desconforto na região superior posterior direita da arcada. Foi observada clinicamente ausência do ponto de contato entre os dentes 15, 16 e 17, optando-se pelo tratamento multidisciplinar envolvendo a ortodontia e a dentística restauradora. Para isso, foram utilizados bráquetes no segundo pré-molar e no primeiro molar superior direito (dentes 15 e 16, respectivamente), e botões ortodônticos nas faces palatinas desses, e do segundo molar superior (dente 17), unidos por elástico corrente tamanho médio. Quando obtidos os pontos de contato, foi realizada a restauração do primeiro pré-molar direito (dente 17) com resina composta. Considerações finais: o uso de elásticos corrente e botões ortodônticos foi satisfatório para a obtenção de pontos de contato entre os dentes.(AU)

The presence of the proximal contact is essential to maintain the periodontal structures health, besides preventing diseases and wastes, thus preserving an ideal occlusion. Aim: the aim of this article is to present a clinical case report with restoration of the proximal contact in a conservative way, through orthodontics and restorative dentistry, in teeth with total crowns. Case report: a 69-year-old female patient attended the university dental clinic with complaint of food impaction and discomfort in the upper right posterior region of the arcade. It was clinically observed absence of the point of contact between the teeth 15, 16 and 17 and opted for the multidisciplinary treatment involving orthodontics and restorative dentistry. For this, brackets were used in the second premolar and first maxillary right molar (teeth 15 and 16, respectively), and orthodontic buttons on the palatal surfaces of the same, and on the second upper molar (tooth 17), joined by the current elastic medium size. When the proximal contact was obtained, the first right premolar restoration was performed with a composite resin. Final considerations: the use of current elastics and orthodontic buttons were satisfactory for obtaining proximal contact between these teeth.(AU)
