The main objective of this study was to evaluate the prevalence of emergencies in dental practices and the preparedness and the training experience in cardiopulmonary resuscitation (CPR) of Brazilian dentists in dealing with emergencies. The volunteer participants in the study were 498 Brazilian dentists who were present at the 27th International Congress of Dentistry in São Paulo. The most prevalent emergency was presyncope (reported by 54.20 percent of respondents), followed by orthostatic hypotension (44.37 percent), moderate allergic reactions (16.86 percent), hypertensive crisis (15.06 percent), asthma (15.06 percent), syncope (12.65 percent), angina (6.82 percent), convulsion (6.22 percent), hypoglycemia (5.62 percent), hyperventilation crisis (5.22 percent), choking (2.20 percent), and cerebrovascular accident (0.8 percent). Anaphylaxis, myocardial infarction, and cardiac arrest were the rarest emergencies, reported by only 0.4, 0.2, and 0.2 percent of dentists, respectively. Only 41 percent of the dentists judged themselves capable to diagnose the cause of an emergency during a dental visit. The majority responded that they would be capable of performing initial treatment of presyncope, syncope, orthostatic hypotension, convulsion, and choking. However, most of them felt unable to treat anaphylaxis, myocardial infarction, or cardiac arrest. Further, the majority felt unable to perform CPR or undertake an intravenous injection. It was concluded that the most prevalent medical emergencies in dental practice of Brazilian dentists are presyncope and orthostatic hypotension. The occurrence of life-threatening medical emergencies like anaphylaxis, myocardial infarction, cardiac arrest, and cerebrovascular accident is rare. Brazilian dentists are not fully prepared to manage medical emergencies and have insufficient experience training in CPR

Objective To evaluate pregnant women's knowledge and perception of oral practices as well as their relationship with periodontal disease. Methods The project was developed in 27 units of the Family Health Strategy in the city of Picos, State of Piauí, Brazil, whose service prioritized providing the first dental appointment for pregnant women. A questionnaire was applied to 302 pregnant women, and a calibrated examiner (Kappa=0.96) performed the intraoral exam (CPI). Results the disease was present in 90.7% of them, although 96.4% had been to the dentist once, the majority have not seen a dentist during pregnancy, either because they feared the treatment would harm the baby, or lack of perceiving the need for doing so. Among those that had seen a dentist, did so because of pain or due to routine dental appointments. (19.9%). The belief that pregnancy could cause oral problems was mentioned by 39.7%, however, the majority (98.3%) stated they had received no guidance in this period, a fact which was shown to be associated with periodontal disease (p=0.0003). Conclusion It was concluded that there had been disease prevalence in the group, becoming persistent throughout pregnancy and also that the women presented many oral health care doubts during their gestational period.

Aim: To evaluate caries prevalence and associated factors in Quilombola communities. Methods: The study involved a cross-sectional study with Quilombola communities in Southeastern Brazil, in 2011. The data were collected by interviews and clinical examination. The sample was checked for caries prevalence (dmft and DMFT index) by one trained and calibrated dentist, reaching acceptable levels of agreement for data collection. The data were analyzed using descriptive statistics and frequency distribution. The significance of the associations between the dependent variable (dental caries) and the independent variables was verified using chi-squared or Fisher's Exact tests. Variables with a p-value <0.25 were tested using multiple logistic regression models in order to keep those with a pd"0.05 value. Odds ratios were estimated using regression models and 95% confidence intervals. The population consisted of 171 quilombolas (97% of total). Results: Mean dmft value was 1.91 (± 2.71) at age d"5 years and mean DMFT values were 1.20 (± 1.49), 3.50 (± 2.23), 10.3 (± 4.79), 22.9 (± 5.37), 22.8 (± 4.12), respectively in the age groups: 6-12, 13-18, 19-34, 35-59 years and 60 years or older. Age less than 5 years (p-value 0.014), own perception of oral health (p-value 0.040) and education level were variables associated with dental caries in permanent teeth and need for treatment in the deciduous dentition. Conclusions: High prevalence of dental caries indicates the need for restructuring the dental care provided to the quilombolas.

O objetivo do presente trabalho foi investigar a inserção e a perspectiva profissional de egressos de Odontologia no mercado de trabalho. Trata-se de um estudo observacional, transversal e descritivo, realizado por meio de um questionário eletrônico aplicado aos 298 egressos de um curso de Odontologia do Tocantins, distribuídos em 14 turmas (2008 a 2015). A taxa de resposta foi de 61,41% (n=183). Após análise dos dados (Teste de Qui-quadrado/Exato de Fisher; nível de significância de 5%) verificou-se que 65,6% dos respondentes eram do sexo feminino, com idade média de 30 (±6,6) anos. O tempo médio de formado foi de 3,7 (±2,2) anos. Dentre os egressos, 37,8% trabalhavam em serviço público, sendo que 17,5% o faziam exclusivamente. A maioria deles trabalhava no estado do Tocantins (65,0%), sendo que 62,8% estava cursando ou cursou pós-graduação, sendo Ortodontia (17,5%), Endodontia (14,8%), Odontopediatria (7,6%); a área de Saúde Coletiva apareceu para 3,8% dos respondentes. A renda mensal da maioria (46,4%) foi de até 5 salários mínimos (R$ 3 640,00) e 49,8% dos respondentes mostraram-se satisfeitos com o rendimento mensal. A inserção imediata no mercado de trabalho foi relatada por 72,7% dos egressos, sendo que 6% não exerciam a profissão naquele momento e destes, 2,7% nunca exerceram. Dentre as disciplinas consideradas mais significativas na graduação apareceram Cirurgia Oral (26,8%), Endodontia (21,3%), Dentística (14,2%), Odontopediatria (11,5%), Prótese (9,3%) e Saúde Coletiva (4,9%).  Os resultados encontrados permitem concluir que a inserção dos egressos no mercado de trabalho foi rápida e a maioria se encontrava satisfeita com os rendimentos naquele momento.

Objective: To evaluate the influence of Coca-Cola ® consumption on the salivary pH of 12-year old children. Material and Methods: The convenience sample was composed of forty-five 12-year old students of both genders from public schools of Itatiba, state of São Paulo, Brazil. Salivary pH was measured with pH colorimetric tape indicator (Merck). The reading of the colorimetric method was made by an experienced evaluator under uniform lighting conditions. The colorimetric tape was positioned in the back of the student's tongue, which remained with the mouth shut for 30 Seconds. For control, the first measurement (T0) was performed before the intake of the soft drink (baseline pH). Subsequently, students were instructed to slowly drink 100 ml of Coca-Cola ® using a plastic disposable cup. Immediately after ingestion, the pH was measured again with the colorimetric tape (t1). The oral pH values were also measured 5 minutes (t2), 10 minutes (t3) and 15 minutes (t4) after the soft drink intake, keeping the tape positioning always the same in all measurements. The statistical SAS software was used for data analysis. Comparisons of oral pH values at different times were performed by the Tukey-Kramer test adopting 5% significance level. Results: Immediately after soft drink intake, the salivary pH significantly decreased (pH = 6.26) (p <0.05) compared to baseline (pH = 7.23) (p <0.05). Fifteen minutes after ingestion, although an increase in the pH was observed (pH = 6.64), it had not yet returned to baseline (T0) (p <0.05). Conclusion: Coca-Cola ® intake caused a significant reduction in salivary pH, without, however, reaching critical pH for enamel demineralization.
