Objectives. To compare the effectiveness of the topical administration of benzocaine and EMLA on oral pain and tactile sensitivity. Materials and Methods. A randomized, double-blind, split-mouth clinical trial was carried out with 20 volunteers. e sensorial and quantitative tests were applied before the contact with topical anesthetic and after the application. Results. In the superficial tactile perception test, when we compared each group singly, there were statistically significant values in the decrease of superficial tactile perception when compared to the moment prior to the application of anesthetic agents. For the sensitivity to mechanical pain, no statistical significant difference was observed at evaluated times. In the needle penetration test, in an intergroup analysis, we found a decrease in the pain sensitivity to needle penetration at 5 min (p � 0.053) and at 10 min (p � 0.019) after the contact of the anesthetic drug with the oral mucosa. Conclusion. e application of topical anesthetic drugs reduces the discomfort associated with this procedure, mainly until the first 10 minutes. Only the needle penetration sensitivity test showed sufficient sensitivity to reveal a difference in the anesthetic effect between EMLA and benzocaine. is trial is registered with RBR-2N2GSW.

Introdução: Pacientes portadores do vírus da imunodeficiência humana apresentam susceptibilidade a desenvolver alterações bucais, em que estas estão intimamente relacionadas ao grau de carga viral e consequentemente a contagem de células linfocitárias. Objetivo: Traçar um perfil clínico-epidemiológico de alterações bucais em pacientes portadores do HIV. Material e Método: Realizou-se uma revisão onde foram analisados artigos científicos obtidos da base de dados PubMed. Foram incluídos os estudos do período de 2000 a 2017, de acordo com os descritores: HIV; Linfócitos T CD4-positivos; Doenças da boca, bem como a associação dos termos. Totalizando-se 19 estudos para realização da pesquisa.  As pesquisas que não se enquadraram a esses critérios foram excluídas. Os dados foram analisados a partir de estatística descritiva. Conclusão: Conclui-se que a cavidade oral é a área de maior frequência para manifestações do HIV/AIDS sendo a candidose, leucoplasia pilosa e as doenças periodontais as lesões mais ocorrentes em todo o mundo. Em relação ao sexo, conclui-se que a maior prevalência varia de acordo com a população estudada, sendo o sexo masculino o mais prevalente no Brasil, porém o sexo feminino quando afetado possuíam idade mais precoce.Descritores: HIV; Linfócitos T CD4-Positivos; Doenças da Boca.

Background:The purpose of the present study is to report twenty cases of children with facial fractures admitted to the department of Oral and Maxillofacial Surgery at Hospital da Restauração/FUSAM -Recife/Brazil and review the English medical literature. Methods and Findings:A retrospective case series study was developed. A total of 20 fractures were treated. Male was the main gender with average age of 8.7 years old. Motor vehicle accident was the main cause of injury (35%). Mandible fracture was the most common type of fracture (80%) and it was unilateral in 75% of cases. The sites most often affected were the symphysis (44%) and condyle (38%). Conclusion: Facial fractures in pediatric patients present importantrepercussions of functional and aesthetics nature. The socioeconomic and environmental aspects directly influence the incidence of facial trauma in this period of life. The parental supervision directly affects the etiologic factors (fall and motor vehicle accidents) and can be used as a factor to prevent these conditions.
