Introduction: Endodontics suffered the influence of a variety of concepts and philosophies that characterized the different periods of its evolution. Foramen Debridement is an endodontic procedure that aims the passive cleaness of cementary channel and can be considered as a pertinent example of controversial topics in endodontics. Objective: To evaluate the attitudes of endodontists in making the foramen debridement of necrotic pulp in cases with and without periapical lesion and which moment they consider convenient to carry out this surgical maneuver. Materials and methods: The study was conducted through a questionnaire to evaluate the knowledge of endodontists of Pernambuco Brazil, about foramen debridement. In this questionnaire could be found general information about identification and specific of foramen debridement procedure and its realization during biomechanical preparation of root canals diagnosed with pulp necrosis with or without periapical lesion radiographically visible. Results: The response rate, a sample of 115 professionals, was 63.5%. Most experts had over 20 years of graduates (49.5%) and when asked if they perform foramen debridement d 97.3% responded yes. Regarding the clinical situation in which perform the foramen debridement only 25.3% answered at all endodontic treatments and 54.9% in all cases necrosis. Conclusion: The results of this research suggest that foramen debridement Consolidated protocols endodontic specialists of Pernambuco.

Biocompatibility is the ability of a material to perform specific tasks when applied to living tissues without causing damage or injuries to it. Thus, this study aimed at determining the in vivo and in vitro biocompatibility of Cissus sicyoides L. -Vitaceae hydroalcoholic extracts. A total of 30 rats (Rattus norvegicus Albinus Wistar), with ages ranging from 45 to 90 days and weighing between 170 and 260g were used. The animals were divided into 3 groups (A1, A2 and A3) with 6 animals each, for the in vivo test, which were sacrificed after 2, 4 and 6 days, respectively. For in vitro test, 12 animals were used to obtain the index of adherence and phagocytic ability of macrophages of rats from the control and the experimental groups. In results found for the in vivo test, it was concluded that the extract was biocompatible, whereas no significant changes were observed in the tissue. As to the in vitro test, the extract was not biocompatible, since the pure extract showed a low rate of adherence (7.1) and a high rate of phagocytosis (35.7), indicating a significant difference when compared to the control group. However, when diluted, the extract was shown to be harmless, due to an increase in the values of the adherence index at the following concentrations : 1/10 (61.4) and 1/100 (74.3) in the tests, which showed no significant differences when compared to the control group. After analyzing the data, it was concluded that since the infusion of the plant is a kind of dilution, its use does not cause any harm to the body. A new study is necessary at the moment to possibily demonstrate its effects on the long term.

The aim of the present study was to determine the effect of a regional basic diet (RBD) on the prevalence of caries in the molar teeth of rats of both sexes aged 23 days. The animals were divided into six groups of 10 rats each receiving the following diets for 30 and 60 days after weaning: RBD, a cariogenic diet, and a commercial diet. The prevalence and penetration of caries in the molar teeth of the rats was then analyzed. The RBD produced caries in 37.5% of the teeth of animals fed 30 days, and in 83.4% of animals fed 60 days, while the cariogenic diet produced caries in 72.5% and 77.5% of the teeth of animals fed 30 and 60 days, respectively. Rats fed the RBD for 30 days had caries in the enamel in 38% of their teeth, 48% had superficial dentin caries, and 7.5% moderate dentin caries. The effect of the RBD did not differ significantly from that of the cariogenic diet in terms of the presence of caries in rats fed 60 days. The penetration depth of the caries produced by the RBD was the same as that produced by the cariogenic diet. Our results show that the RBD has the same cariogenic potential as the cariogenic diet. Since the RBD is the only option for the lowincome population, there should be a study of how to compensate for the cariogenicity of this diet.

O objetivo deste trabalho foi avaliar a percepção dos alunos envolvidos no projeto de Excursão Didática a respeito da integralidade da atenção à saúde e da integralização ensino, trabalho e práticas sociais. Trata-se de um estudo observacional do tipo analítico. A amostra foi composta de 109 alunos que participaram das excursões e que estavam cursando entre o 7º e o 10º período do curso de Odontologia da Universidade Federal de Pernambuco (UFPE). As atividades das excursões foram desenvolvidas nas cidades do sertão pernambucano. O questionário aplicado para coletar as informações dos participantes foi composto por quatro partes: Dados pessoais (nome, idade, sexo e período do curso); Infraestrutura necessária para a excursão (transporte, recurso financeiro e duração da atividade); Abordagem clínica (acolhimento, relacionamento dos profissionais com os pacientes e famílias, biossegurança e domínio das atividades clínicas); e Resultado final da excursão. Quase a totalidade da amostra dos estudantes entendeu como adequada a metodologia utilizada durante todo o transcurso da atividade. As atividades extramuros desenvolvidas nas comunidades cumpriram seu principal objetivo, que foi proporcionar aos alunos uma visão integral da realidade social e sanitária encontrada nas comunidades não assistidas pelos serviços básicos de saúde.
