O objetivo deste trabalho foi avaliar a percepção dos alunos do ensino técnico em relação à modalidade de Educação a Distância (EaD). Participaram do estudo 61 discentes, distribuídos em dois grupos: G1 (n=32), composto por alunos de cursos presenciais, e G2 (n=29), composto por alunos de cursos de EaD. Para a coleta de dados, foi utilizado um questionário já validado, que verificou a percepção dos alunos sobre a modalidade de EaD. As informações coletadas revelaram que 28 participantes do G1 (87,5%) e 16 do G2 (55,2%) concordavam em parte ou totalmente que os cursos de EaD apresentavam menor qualidade de ensino quando comparados aos cursos presenciais, sendo essa diferença percentual entre os grupos estatisticamente significante (p=0,002). Em seguida, verificou-se a percepção dos alunos de EaD quanto ao acesso ao professor e às atividades realizadas na plataforma Moodle. Com relação ao contato com os docentes, apenas 3 alunos (10,3%) consideraram esse contato fácil. Quando analisadas as atividades online, 26 (89,7%) classificaram estas como regulares, boas ou ótimas. Diante do exposto, pode-se concluir que a maioria dos discentes considerava que os cursos de EaD tinham menor qualidade quando comparados aos cursos presenciais, entretanto esta percepção é significativamente menor entre os alunos da modalidade de ensino a distância.

This study aimed to evaluate the effect on oral health-related quality of life (OHRQoL) of two treatment protocols for dental fluorosis in individuals enrolled in a randomized clinical trial. Seventy volunteers, who lived in a fluorosis endemic area in Brazil, and had at least four maxillary anterior teeth showing fluorosis with a Thylstrup and Fejerskov index from 1 to 7, were randomized into two treatment groups (n= 35): GI- enamel microabrasion; or GII- microabrasion associated with at-home bleaching. Microabrasion was performed using 37% phosphoric acid and pumice, and at-home tooth bleaching with 10% carbamide peroxide in a tray. Volunteers completed a questionnaire at baseline and 1-month post treatment to assess changes in OHRQoL, using the Oral Impact on Daily Performance (OIDP). Differences in overall impact scores between and within treatment groups were analyzed with Wilcoxon (within) and Mann-Whitney (between) tests. Changes in performance scores were analyzed using Wilcoxon tests (a< 0.05). One month after treatment, subjects reported improvement in OHRQoL. Both groups showed lower OIDP scores (p< 0.001), but there was no difference between them. Eating, cleaning teeth, smiling and emotional state performance scores were lower after treatment for the whole sample. In conclusion, the treatment with microabrasion improved the OHRQoL in this sample of individuals living in a fluorosis endemic area regardless of the addition of at-home bleaching.

Objectives This parallel randomized clinical trial evaluated the efficacy of two treatments for removing fluorosis stains. Methods Seventy individuals living in an area endemic for fluorosis, with at least four maxillary anterior teeth presenting fluorosis with a Thylstrup and Fejerskov index from 1 to 7, were randomized into two treatment groups (n = 35): GI – enamel microabrasion or GII – microabrasion associated with at-home bleaching. Microabrasion was performed using 37% phosphoric acid and pumice and, at-home tooth bleaching was performed with 10% carbamide peroxide. Areas of enamel opacities were recorded by digital camera at baseline and 1-month (1 M) after treatment. Two blinded examiners evaluated the reduction in the area (mm2) of opacity using software. Two visual analogue scales were used: one for recording tooth sensitivity and/or gingival irritation ranging from 1 (none) to 5 (severe) and the other to evaluate participant satisfaction with the treatment used ranging from 1 (no improvement) to 7 (exceptional improvement). Results 1 M after treatment, both groups showed a significant reduction in the area of enamel opacity (p = 0.0001) and there was no difference between groups (p = 0.1). Most of the participants from both treatment groups reported no or mild tooth sensitivity and gingival irritation (p > 0.05). Participants reported that they were happy with the improvement in dental appearance, however, individuals from GII reported that they were happier than those from GI (p = 0.004). Conclusions Both treatment protocols were effective in reducing fluoride stains, however, when home bleaching was associated to enamel microabrasion, patients reported a major satisfaction with dental appearance.

Objective To determine the prevalence of syphilis and the associated risk factors in a female prison unit. Methods This was a cross-sectional study including 113 women whom data were collected in two stages: first, blood test to check for syphilis seropositivity; and then collection of information through a form to assess risk situations for sexually transmitted infections. Results Overall, syphilis prevalence was found to be 22.1% among the female prison population (n=25) and 28.6% among pregnant women. A statistically significant relationship was found between syphilis infection and previous history of sexually transmitted infections (p=0.04). However, most participants diagnosed with the disease were unaware of a history of sexually transmitted infection in the last 12 months (n=20/80.0%). The use of condom with fixed partners was considered to be a protective factor (odds ratio of 0.76; 95% of confidence interval 0.68-0.85). Conclusion The prevalence of syphilis among the female prison population was high, particularly among pregnant women. Preventive and therapeutic measures as well as appropriate prenatal care can minimize the impact of syphilis in prison systems and, consequently, improve such health outcomes nationwide. RESUMO Objetivo Determinar a prevalência de sífilis e fatores de risco associados no sistema prisional feminino. Métodos Foi realizado estudo transversal com 113 mulheres. A coleta de dados ocorreu em duas etapas: a primeira etapa correspondeu à coleta de sangue para verificar a soropositividade à sífilis e a segunda a um formulário para avaliar situações de risco para infecções sexualmente transmissíveis. Resultados A prevalência da doença foi de 22,1% (n=25). Quanto às gestantes, identificou-se prevalência de 28,6%. Foi verificada relação estatisticamente significativa entre a infecção pela sífilis e a história prévia de infecções sexualmente transmissíveis (p=0,04). Entretanto, a maioria das participantes diagnosticadas com a doença desconhecia um histórico de infecção sexualmente transmissível nos últimos 12 meses (n=20/80,0%). O uso de preservativo com parceiros fixos foi considerado fator de proteção (odds ratio de 0,76; intervalo de confiança de 95% de 0,68-0,85). Conclusão Foi alta a prevalência de sífilis na população carcerária feminina estudada, principalmente entre as gestantes. Medidas preventivas e de tratamento da doença, bem como cuidados pré-natais adequados, podem minimizar o impacto da sífilis nos sistemas prisionais e, consequentemente, melhorar esse indicador de saúde no país.
