RESUMO
Introduction: Postoperative management of patients undergoing tonsillectomy is challenging. Photobiomodulation therapy (PBMT) has emerged as a new tool providing therapeutic benefits. However, the contribution of PBMT to the postoperative outcomes of tonsillectomy is still undefined. This systematic review and meta-analysis evaluated the published literature addressing the effects of PBMT on post-tonsillectomy. Methods: Searches in Scopus, PubMed/MEDLINE, Embase, Web of Science, Cochrane Library, and grey literature were carried out for the identification of randomised controlled trials reported up to August/2021. The risk of bias with the Cochrane Collaboration tool and meta-analysis was performed. Outcomes were assessed with the Kaplan-Meier method and the log-rank test. Results: A total of 1183 articles were retrieved, of which only two were included for qualitative and quantitative analysis. The wavelengths were 685 nm and 980 nm with energy density set at 4 J/cm2. The mandibular angle and the surgical wound were the sites of laser irradiation. Individuals who had not undergone PBMT after tonsillectomy were more likely to report pain and odynophagia in the first 24 hours after surgery than individuals who had undergone PBMT after tonsillectomy (P<0.001). Children who received PBMT after tonsillectomy were equally affected by pain and odynophagia in the first seven days after surgery compared to children who had not undergone PBMT after tonsillectomy (P>0.05). However, both studies found a significant association of PBMT with reduced analgesic consumption. Conclusion: Although PBMT seems promising for the management of individuals undergoing tonsillectomy, a limited number of studies are available in the literature.
RESUMO
BACKGROUND: MCs (MCs) have been ascribed to mediating several diseases, including malignant neoplasms. These cells can play a role in angiogenesis, tissue remodeling and immune modulation and favor neoplasm progression. Despite the studies analyzing the contribution of MCs in odontogenic lesions, its biological behavior in ameloblastomas (AMBs) and odontogenic keratocysts (OKCs) remains unclear. This study aims to detect MCs in OKCs and AMBs and clarify the role of MCs in these lesions. MATERIAL AND METHODS: A total of 40 odontogenic lesions were analyzed. This included 20 OKCs and 20 AMBs, 10 being the solid type and the other 10 being the unicystic type of AMB. All cases were histologically reviewed in hematoxylin-eosin. Clinical data, such as age, gender, location, size, radiographic presentation and, histologic patterns were collected from the clinical charts. The Mann-Whitney U test (MWU) was used verify the hypothesis, through inferential statistics. The level of significance used in the statistical test was 0.5%. RESULTS: MCs were observed in 60% of OKCs, and 35% of AMBs. The ratio of MCs observed in OKCs was 0.37, 0.48 in solid AMBs and 0.01 in unicystic AMBs. There was no significant difference between number of MCs in AMBs and OKCs, however, a significant difference was observed between solid and unicystic AMBs (p ≤ 0.01). CONCLUSIONS: MCs may play an important role in the biological behavior of AMBs and OKCs. However, in this study it was not possible to confirm the contribution of MCs in the biological behavior of these lesions and more studies are needed to clarify this relation. Key words:AMB, OKC, MCs, histochemistry, toluidine blue.
RESUMO
ABSTRACT Objective: The aim of the present study was to locate mast cells in chronic periapical lesions (granulomas and cysts) by using histochemical techniques and toluidine blue staining. Methods: A quantitative, descriptive, cross-sectional and retrospective research was performed. The sample was obtained from histopathological reports in the archives of the laboratory of surgical pathology of the University of Pernambuco between November 2014 and May 2015. Results: Sixteen cases of granuloma and 21 cases of periapical cysts were selected. The stained slides were analyzed by two examiners at different times, in a double-blind study. Mast cells were found in 13 (61.9%) of the periapical cyst cases, located in the capsule of the lesion. In the periapical granuloma cases, mast cells were found in eight cases (50%), located in the granulation tissue. Conclusion: Mast cells were detected in both cysts and periapical granuloma, located in the capsule and granulation tissue, respectively. Mast cells were more prevalent in periapical cysts than in periapical granuloma.
RESUMO Objetivo: Localizar mastócitos em lesões periapicais (granulomas e cistos) através de técnicas histoquímicas e corante azul de toluidina. Métodos: Uma pesquisa quantitativa, descritiva, transversal e retrospectiva foi realizada. As amostras foram obtidas de documentos histopatológicos nos arquivos do laboratório de patologia cirúrgica da Universidade de Pernambuco entre Novembro de 2014 e Março de 2015. Resultados: Dezesseis casos de granuloma e 21 casos de cistos periapicales foram selecionados. As lâminas coradas foram analisadas por dois examinadores em tempos diferentes, em um estudo duplo-cego. Mastócitos foram encontrados em 13 (61,9%) dos casos de cistos periapicales, localizados na cápsula da lesão. Nos granulomas periapicais, mastócitos foram encontrados em oito casos (50%), localizados no tecido de granulação. Conclusão: Mastócitos foram detectados tanto em cistos quanto em granulomas periapicais, localizados na cápsula e no tecido de granulação respectivamente. Os mastócitos estavam mais presentes nos cistos do que nos granulomas periapicais.
RESUMO
Cistos e granulomas periapicais estão entre as lesões radiolúcidas mais prevalentes. Porém, há situações em que os padrões clínicos e radiográficos se misturam e, portanto, o estudo histopatológico faz-se necessário para o diagnóstico definitivo. O objetivo deste estudo foi avaliar a correlação clínica e histopatológica no diagnóstico de cistos e granulomas periapicais. Para isso, foram selecionadas amostras obtidas no Laboratório de Patologia Cirúrgica da Faculdade de Odontologia de Pernambuco, FOP/UPE, no período de 11/2005 a 05/2008. Um total de 37 lesões, distribuídas entre cistos e granulomas periapicais, foram incluídas no estudo. Baseadas nos aspectos clínico-radiográfico e transoperatório, cirurgiões-dentistas forneceram hipóteses diagnósticas, as quais foram comparadas aos exames histopatológicos. Achados clínicos revelaram 28 casos (75,7%) de cistos, 4 casos (10,8%) de granulomas, 4 casos (10,8%) com características de ambas lesões, e 1 caso (2,7%) no qual o dentista não forneceu o diagnóstico. Entretanto, os achados histopatológicos revelaram 21 (56,8%) e 16 (43,2%) casos de cistos e granulomas, respectivamente. Os resultados mostraram uma correlação de 45,9% entre os achados para os cistos e de 8,1% para os granulomas. Diante do exposto, a discrepância observada dos achados clínicos quando comparados aos histopatológicos deve ser discutida quanto aos critérios diagnósticos que vêm sendo utilizados atualmente...

Cysts and periapical granulomas are among the most prevalent radiolucent lesions. However, there are situations where the clinical and radiographic patterns are mixed and therefore the histopathological study is necessary for definitive diagnosis. The aim of this study was to evaluate the clinical and histopathological correlation in the diagnosis of periapical cysts and granulomas. For this, samples were selected obtained from histopathological reports of Pathology Laboratory, Faculty of Dentistry of Pernambuco, FOP / UPE, during the period from 11/2005 to 05/2008. A total of 37 lesions distributed among periapical cysts and granulomas, were included in the study. Based on clinical, radiographic and intraoperative lesions, dentists provided diagnostic hypotheses, which were compared to histopathological diagnostic. Clinical findings revealed 28 cases (75.7%) of radicular cysts, 4 cases (10.8%) of granulomas alone, 4 cases (10.8%) with characteristics of both lesions, and 1 case (2.7 %) in which the dentist has not provided the diagnosis. However, the histopathological findings revealed 21 (56.8%) and 16 (43.2%) cysts and granulomas images, respectively. The results showed a 45.9% correlation between the findings for periapical cysts and 8.1% for periapical granulomas. Given the above, the discrepancy observed clinical findings compared to histopathology should be discussed as to the diagnostic criteria that have been used nowadays... (AU)

RESUMO
A síndrome de Stevens-Johnson (SSJ) é uma variante do eritema multiforme pela conformação e distribuição das lesões cutâneas e maior gravidade do envolvimento mucoso. É caracterizada pela ação de anticorpos IgG ou IgM específicos para drogas. Apresenta importante papel na Odontologia pois que muitas vezes as primeiras manifestações desta doença ocorrem na mucosa bucal. O objetivo deste trabalho é apresentar um relato de um paciente portador da SSJ, sexo masculino, 53 anos, com queixa inicial de dor e ardência bucal. Ao exame clínico verificou-se lesões e crostas hemorrágicas evidentes no vermelhão dos lábios e mucosa bucal. Relatou que foi atendido anteriormente em um serviço oftalmológico e diagnosticado com conjuntivite e que estava sob uso das seguintes medicações: alopurinol, nimesulida, sinvastatina, omeprazol e frontal. O quadro do paciente evoluiu rapidamente para as lesões em pele e por esta razão internado e submetido a protocolo do setor de queimados de um hospital particular. Atualmente o paciente apresenta as seguintes sequelas: cegueira do olho esquerdo, simbléfaro e pterígio nasal. O conhecimento dessa síndrome, pelo cirurgião-dentista é de fundamental importância, vez que, o estabelecimento do diagnóstico precoce pode minimizar as sequelas e até mesmo evitar casos extremos de óbito. Por fim, esclarecer e conscientizar os profissionais quanto ao uso indiscriminado de medicamentos, causa hoje reconhecida para esta síndrome... (AU)
The Stevens-Johnson syndrome (SJS) is a variant of erythema multiforme by the conformation and distribution of skin lesions and more severe mucosal involvement. It is characterized by the action of specific drugs for IgG or IgM antibodies. Plays an important role in dentistry since often the first manifestations of this disease occur in the oral mucosa. The objective of this paper is to present a report of a patient with SJS, male, 53 years, with an initial complaint of pain and burning mouth. On clinical examination there was injury and hemorrhagic crusts evident in the vermilion of the lips and buccal mucosa.

RESUMO
Objetivo: O presente estudo procurou acessar o efeito da limpeza do forame apical no reparo de lesões periapicais detectadas radiograficamente. Materiais e métodos: A amostra constituiu-se de 980 dentes selecionados de 25 de fevereiro de 1997 a 15 de março de 2005 que foram submetidos a tratamento endodôntico e exibiram lesões periapicais radiograficamente visíveis. A amostra foi então divididaem dois grupos: Grupo I, 402 tratamentos de canal em que a limpezado forame apical não foi realizada, e Grupo II, composto pelos 578 dentes restantes onde o procedimento foi realizado. Após um ano, os dentes foram clinica e radiograficamente avaliados.Resultados: No Grupo I, 360 canais (89,55%) não tiveram evidência de lesões periapicais, versus 521 (90,13%) no Grupo II. Presençaparcial dessas lesões foi observada em 23 canais (5,72%) no Grupo I versus 27 (4,67%) no Grupo II. O teste qui-quadrado de Pearson não demonstrou significância estatística entre os Grupos I e II (p=0,732).Conclusões: Estes achados sugerem que a limpeza do forame apical não é um determinante para o reparo de lesão periapical.
Aim: The present study sought to assessthe effect of apical foramen cleaningin the repair of periapical lesionsdetected by radiography. Methods:The sample comprised 980 teeth collected from 25 February 1997 to15 March 2005, which had been subjected to endodontic treatment and exhibited radiographically visibleperiapical lesions. The sample wasthen divided into two groups: Group I,402 root canal treatments in which cleaning of the apical foramen had notbeen performed, and Group II, composed of the remaining 578 rootcanal treatments where the procedure had been performed. After one year, the teeth were clinically and radiographically evaluated. Results: In Group I, 360 canals (89.55%) had no evidence of periapical lesions, versus 521 (90.13%) in Group II. Partial presence of thes e lesions was observedin 23 canals (5.72%) in Group I versus27 (4.67%) in Group II. No changes in images were observed in 19 (4.72%)canals in Group I and 30 in Group II. Pearsons chi-square test showed nostatistically significant difference between the Groups I and II (p =0.732).Conclusions: These findings suggest thatforamen cleaning is not a determinantof periapical lesion repair.

PURPOSE: To evaluate the bone healing of mandibular fractures following the use of Portland cement. METHODS: Thirty-two male Wistar rats were divided into control and experimental groups. In the control group the rats were submitted to a mandibular fracture, which was reduced, and the soft tissues were sutured. In the experimental group the rats had the mandibular fracture reduced and maintained with the Portland cement. The animals were euthanized 7 and 21 days after surgery by injecting a lethal dose of anesthetic. The following variables were studied: weight of the animals, radiographic images, histopathological features and time of surgery. RESULTS: A weight loss was observed in the specimens of both groups at the different times of evaluation, a greater difference in weight before and after surgery being found in the experimental group, which was statistically significant (p <0.05, p = 0.041). From the histological point of view, with a margin of error (5.0 percent) the only two significant differences (p <0.05) recorded in the variables were "Material deployed" and "Bone resorption" during the evaluations at 7 and 21 days, respectively. CONCLUSION: The Portland cement served to promote bone healing.
OBJETIVO: Avaliar a reparação óssea de fratura mandibular após o uso do cimento Portland (CP). MÉTODOS: Trinta e dois ratos machos Wistar foram divididos em grupo controle e grupo experimental. No grupo controle os ratos foram submetidos à fratura, redução e manutenção dos seguimentos com sutura dos tecidos moles. No grupo experimental foram submetidos a fratura, redução e manutenção dos segmentos fraturados com CP e sutura dos tecidos. Os animais foram eutanasiados com sete e 21 dias de pós-operatório através da injeção de dose letal dos anestésicos adotados. As variáveis estudadas foram: peso dos animais, avaliação tomográfica, avaliação histológica e tempo cirúrgico. RESULTADOS: Perda de peso foi observada nos espécimes de ambos os grupos nos diferentes intervalos de tempo considerados, sendo maior a diferença de peso antes e após cirurgia para o grupo experimental, que foi estatisticamente significante (p<0,05; p=0,041). Do ponto de vista histológico para a margem de erro fixada (5,0 por cento) as duas únicas diferenças significativas (p<0,05) foram registradas nas variáveis: "Material implantado" na avaliação com sete dias e "Reabsorção óssea" na avaliação com 21 dias. CONCLUSÃO: O cimento Portland atuou promovendo a reparação óssea.
