RESUMO

Introdução: A Odontologia vem se aprimorando com a utilização de novos métodos terapêuticos, como por exemplo, a incorporação de práticas integrativas e complementares (PIC), com base na perspectiva de estabelecer novas ferramentas de atendimento integral e atuação transdisciplinar. Objetivo: Avaliar a quantidade e a distribuição de cirurgiões-dentistas habilitados em fitoterapia, terapia floral, hipnose, laserterapia, odontologia antroposófica, ozonioterapia e de especialistas em acupuntura e homeopatia, de acordo com os estados e regiões brasileiras. Material e Métodos: Tratou-se de uma pesquisa transversal, com abordagem descritiva, a partir de dados secundários e de acesso público, provenientes do Conselho Federal de Odontologia (CFO). Resultados: No Brasil, há 2.932 cirurgiões-dentistas habilitados ou especialistas em PIC, havendo um maior número de registros na prática da laserterapia (n= 1.571; 53,6%), seguida por acupuntura (n= 497; 16,9%). Dentre as PIC avaliadas, observou-se, no país, um menor número de registros na prática fitoterapia (n= 26; 0,9%), seguida por odontologia antroposófica (n= 36; 1,2%) e terapia floral (n= 49; 1,7%). Por regiões brasileiras, verifica-se que a região Sudeste detém o maior número de profissionais habilitados ou especialistas em todas as PIC avaliadas. As regiões Norte e Nordeste não apresentam profissionais habilitados em odontologia antroposófica (n= 0; 0%). Em todo o Brasil, observou-se na laserterapia, o maior número de habilitados por cirurgião-dentista, com uma proporção de 1/232. Dentre todos os estados, o Espírito Santo detém a maior proporção observada entre as PIC avaliadas, na prática da laserterapia (1/82). Conclusão: Com base nos resultados encontrados e de acordo com o grande número total de cirurgiões-dentistas em atividade no Brasil, concluiu-se que ainda existem poucos profissionais habilitados em fitoterapia, odontologia antroposófica, terapia floral, hipnose, ozonioterapia, laserterapia, e especialistas em homeopatia e acupuntura em todo o país. Além disso, nota-se discrepâncias importantes relacionadas ao número desses profissionais entre estados e regiões brasileiras.

Introduction: Dentistry has been improving with the use of new therapeutic methods, such as the incorporation of Integrative and Complementary Practices (PIC), based on the perspective of establishing new tools for comprehensive care and transdisciplinary action. Objective: To evaluate the number and distribution of qualified dentists in phytotherapy, floral therapy, hypnosis, laser therapy, anthroposophic dentistry, ozone therapy and specialists in acupuncture and homeopathy, according to Brazilian states and regions. Material and Methods: This was a cross-sectional study, with a descriptive approach, based on secondary and publicly accessible data from the Federal Council of Dentistry (CFO). Results: In Brazil, there are 2,932 qualified dentists or specialists in PIC, with a greater number of records in the practice of laser therapy (n= 1,571; 53.6%), followed by acupuncture (n= 497; 16.9%). Among the evaluated PICs, it was observed, in the country, a smaller number of records in the practice of phytotherapy (n= 26; 0.9%), followed by anthroposophic dentistry (n= 36; 1.2%) and floral therapy (n= 49; 1.7%). By Brazilian regions, it appears that the Southeast region has the largest number of qualified professionals or specialists in all the evaluated PICs. The North and Northeast regions do not have qualified professionals in anthroposophic dentistry (n= 0; 0%). In all of Brazil, laser therapy had the highest number of qualified professionals per dentist, with a ratio of 1/232. Among all the states, Espírito Santo has the highest proportion observed among the evaluated PICs, in the practice of laser therapy (1/82). Conclusion: Based on the results found and according to the large total number of dentists working in Brazil, it was concluded that there are still few professionals qualified in phytotherapy, anthroposophic dentistry, floral therapy, hypnosis, ozone therapy, laser therapy, and specialists in homeopathy and acupuncture across the country. In addition, there are important discrepancies related to the number of these professionals between Brazilian states and regions.

RESUMO

Abstract Objective: To evaluate the effectiveness of Antimicrobial Photodynamic Therapy (aPDT), associated with scaling and root planing in the non-surgical periodontal treatment of individuals with Down Syndrome. Material and Methods: A controlled, randomized, split-mouth study was conducted. A total of 8 participants diagnosed with Down Syndrome aged 17-38 years of both sexes with clinical periodontitis were included in the study. Participants were treated at least three times: at the baseline, Plaque Index (PI), Bleeding on Probing (BOP), and Probing Pocket Depth (PPD) were obtained. After one week, conventional scaling and root planing were performed, and two quadrants were randomly selected for aPDT application. The reassessment was obtained one month after the aPDT application. The significance level was set at 5%. Analyses were performed considering a 95% confidence interval. Results: In the intergroup evaluation, no statistically significant differences were observed (p>0.05). In the intragroup evaluation, no statistically significant variations were observed in relation to the PI (p>0.05) and PPD (p>0.05); however, a statistically significant reduction in the BOP was observed between the test group (p=0.013) and control group (p=0.015). Conclusion: The use of aPDT as adjuvant therapy did not promote additional benefits in decreasing PI and PPD after 1 month of treatment. However, a significant reduction in the BOP was observed in the intragroup evaluation.

RESUMO

BACKGROUND: Dentin hypersensitivity (DH) is defined as an exaggerated sensitivity of vital dentin exposed to thermal, chemical and tactile stimuli. This study aimed to evaluate, through a literature review, the applicability of high- and low-intensity lasers in the treatment of DH for the past 10 years, as well as its therapeutic potential. MATERIAL AND METHODS: The electronic databases MEDLINE/PubMed and LILACS were searched using the descriptors ("Dentin Sensitivity" OR "Dentin Hypersensitivity") AND ("Low-Level Therapy" OR Laser), for articles published between 2010 and 2020. Only randomized clinical trials with full-text and full case resolution were included. RESULTS: We found 187 articles in total, among which 61 were pre-selected and 10 included in this literature review. CONCLUSIONS: Considering the found results and their possible limitations, high- and low-intensity lasers, associated or not with other therapies, have demonstrated beneficial effects in the treatment of DH, being considered a promising, safe, easy, and effective field of research, reducing pain sensitivity and preserving pulp vitality. Key words:Dentin sensitivity, dentistry, laser.

RESUMO

Oral paresthesia is a localized condition of sensory abnormality that occurs in the presence of injury in one of the nerves in the region after certain dental procedures. The aim of this study was to present a case report of a patient who received low-level laser therapy as treatment for inferior alveolar nerve paresthesia due to mandibular third molar extraction surgery. A 25-year-old female patient reported lack of sensitivity for 6 months in various regions of the bucomaxillofacial complex after surgery. Laser therapy (808 ± 10nm, 100 mW, 3J per point and 30 seconds per point) was indicated twice a week. The degree of sensitivity was evaluated using a Visual Analog Scale (VAS) and with the aid of a microbrush. Prior to laser therapy, the patient reported VAS = 10, i.e., total lack of sensitivity. After 72 hours of the first session, the patient reported improvement of sensitivity in the chin (VAS = 5) and oral regions (VAS = 5), reporting recovery of sensitivity and that the area of paresthesia decreased. After 8 sessions, the patient reported total recovery of sensitivity in the chin, oral and gum regions (VAS = 0), with paresthesia being limited only to the left lower lip region and below it. After 26 sessions, the patient reported recovery of sensitivity in all affected regions (VAS = 0), with positive responses to the brush touch. Within the parameters used, laser therapy was effective in the treatment of inferior alveolar nerve paresthesia after third molar tooth extraction. Key words:Lasers, paresthesia, oral surgery, low-level laser therapy.

RESUMO

The aim of this study was to evaluate the photobiomodulation of red and green lights in the repair process of third-degree skin burns in rats through clinicopathological and immunohistochemical parameters. Sixty male Wistar rats were divided into three groups: control (CTRL) (n = 20), red LED (RED) (n = 20), and green LED (GREEN) (n = 20), with subgroups (n = 5) for each time of euthanasia (7, 14, 21, and 28 days). Daily applications in RED (λ630 ± 10 nm, 300 mW) and GREEN groups (λ520 ± 30 nm, 180 mW) were performed at four points of the wound (total 36 J/cm2 in RED and 240 J/cm2 in GREEN). After euthanasia, the wound retraction index (WRI) was evaluated. In histological sections, the re-epithelialization degree, the angiogenic index (AI), and the amount of myofibroblasts in wounds were analyzed. At 14 and 21 days, the RED group induced higher re-epithelialization and WRI compared to CTRL (p > 0.05) and GREEN groups (p < 0.05). At 7 and 14 days, greater AI were observed in the GREEN group, with significant difference in relation to CTRL group at 7 days (p < 0.05). At 21 and 28 days, a trend was observed for greater amount of myofibroblasts in the GREEN group, with significant difference in relation to CTRL group at 21 days (p < 0.05). The results suggest greater potential of the green light to stimulate angiogenesis in the initial periods and myofibroblastic differentiation in the final periods of the repair of third-degree skin burns. Red light may stimulate further re-epithelialization and wound retraction, especially in advanced repair phases.

RESUMO

The aim of this study was to investigate the Brazilian scientific production about acupuncture in dentistry, outlining the profile of the works about the subject presented at the Meetings of the Brazilian Society of Dental Research (SBPqO). It was a cross-sectional study, with a quantitative approach, based on secondary data. An analysis of all abstracts presented in the last ten SBPqO Meetings (2009-2018) published in the annals of the event was carried out. For the research the location of the term "acupuntura" or "acupuncture" among the abstracts was realized and the following information was collected: type of institution that carried out the research (public or private), Brazilian region where it was realized, area or specialty of dentistry and whether it involved humans or animals. Of the 26,514 dental research abstracts published in the annals, only 27 papers were experimental studies or systematic reviews about the subject. Of the total, 23 (85.2%) were developed in public institutions, 15 (55.6%) did not receive financial support 20 (74.1%) were carried out in humans and 13 (48.2%) were developed in the Southeast region. Regarding the dental specialty, the majority (70.4%) investigated acupuncture in "Temporomandibular Dysfunction and Orofacial Pain". Therefore, it can be concluded that few acupuncture studies in dentistry have been developed in the last ten years in Brazil, according to the papers presented at the SBPqO Meetings. Thus, it is suggested that research on the subject be carried out and widely disseminated between the academic and professional milieu. (AU)

O objetivo desse estudo foi investigar a produção científica brasileira sobre a acupuntura na odontologia, traçando o perfil dos trabalhos sobre a temática apresentados nas Reuniões da Sociedade Brasileira de Pesquisa Odontológica (SBPqO). Tratou-se de um estudo transversal, com abordagem quantitativa, a partir de dados secundários. Realizou-se uma análise de todos os resumos apresentados nas últimas dez Reuniões da SBPqO (2009-2018) publicados nos anais do evento. Para pesquisa procedeu-se a localização do termo "acupuntura" ou "acupuncture" entre os resumos e foram colhidas as seguintes informações: tipo de instituição que realizou a pesquisa (pública ou privada), região rasileira onde foi realizada, recebimento de auxílio financeiro, área ou especialidade da odontologia e se envolvia humanos ou animais. Dos 26.514 resumos de pesquisa odontológica publicados em anais, apenas 27 trabalhos tratavam de estudos experimentais ou revisões sistemáticas sobre a temática. Do total, 23 (85,2%) foram desenvolvidos em instituições públicas, 15 (55,6%) não receberam auxílio financeiro, 20 (74,1%) foram realizados em humanos e 13 (48,2%) desenvolvidos na região Sudeste do Brasil. Com relação a especialidade odontológica, a maioria (70,4%) pesquisou sobre a acupuntura na "Disfunção Temporomandibular e Dor Orofacial". Os achados do presente estudo indicam que poucas pesquisas abordando a acupuntura na odontologia foram desenvolvidas nos últimos dez anos no Brasil, de acordo com os trabalhos apresentados nas Reuniões da SBPqO. Diante disso, sugere-se que pesquisas sobre o tema sejam realizadas e amplamente divulgadas entre o meio acadêmico e profissionais. (AU)

RESUMO

Este estudo teve como objetivo investigar a produção científica brasileira sobre Metodologia da Problematização (MP) e Aprendizagem Baseada em Problemas (PBL) na Odontologia. Tratou-se de uma pesquisa transversal, com abordagem quantitativa, a partir de dados secundários. Para tal, realizou-se uma análise bibliométrica dos resumos apresentados nas últimas dez Reuniões da Sociedade Brasileira de Pesquisa Odontológica ­ SBPqO (2007-2016). A pesquisa dos trabalhos procedeu-se através da seguinte estratégia: localização da sigla "PBL" ou do fragmento "problem" entre os resumos publicados nos anais do evento. Após aplicação dos critérios de inclusão e exclusão, dos 902 resumos encontrados, excluiu-se 890, permanecendo apenas 12 resumos. Desses, 9 (75,0%) foram pesquisas realizadas em universidades públicas, 8 (66,7%) na região Sudeste do Brasil e apenas 1 (8,3%) recebeu apoio financeiro. Apesar da MP e do PBL serem considerados metodologias ativas importantes no processo de ensino-aprendizagem, diante dos resultados encontrados nesse estudo, conclui-se que poucas pesquisas abordando esses métodos na Odontologia foram desenvolvidas nos últimos dez anos no Brasil, de acordo com os trabalhos apresentados nas Reuniões da SBPqO (AU).

This study aimed to investigate the Brazilian scientific production on Problematization Methodology (PM) and Problem-Based Learning (PBL) in Dentistry. It was a transversal research, with a quantitative approach, based on secondary data. For that, a bibliometric analysis of the abstracts presented in the last ten Meetings of the Brazilian Society of Dental Research - SBPqO (2007-2016) was carried out. The research performed using the following strategy: location of the abbreviation "PBL" or the fragment "problem" among the abstracts published in the annals of the event. After applying the inclusion and exclusion criteria, 902 abstracts were found, 890 were excluded, remaining only 12 abstracts. Nine (75.0%) were researches carried out in public universities, 8 (66.7%) in the Southeast region of Brazil and only 1 (8.3%) received financial support. Although MP and PBL are considered important active methodologies in the teaching-learning process, given the results found in this study, it is concluded that few studies addressing these methods in dentistry have been developed in the last ten years in Brazil, according to the SBPqO Meetings (AU).
