The purpose of this study was to evaluate the antimicrobial activity of two experimental pastes containing propolis extract associated with calcium hydroxide against polymicrobial cultures collected from 16 necrotic and fistulae root canals in primary molars of 4-8-yearold children of both sexes. The agar-well diffusion technique was used to determine the antimicrobial activity of the following pastes: 11.0% ethanolic extract of propolis (EEP) + calcium hydroxide; and 11.0% extract of propolis without ethanol (EP) + calcium hydroxide. EEP, EP and the association of calcium hydroxide and propylene glycol (CHP) was used as the positive control groups, and propylene glycol was used as a negative control group. Friedman and Wilcoxon tests were used to compare the data from the microbial growth inhibition zones (p<0.05). Paste 1 and Paste 2 showed larger growth inhibition zones against microorganisms from root canal samples than CHP (p=0.021 and 0.003, respectively). Paste 2 tended to have larger growth inhibition zones than Paste 1 (p=0.053). The association between propolis and calcium hydroxide was effective in controlling dental infections in vitro.

ccording to the current paradigm for promoting health, dental care should be a consideration from the first months of life, or even before birth. The aim of this paper is to evaluate mothers' knowledge of and attitude toward their babies' oral health after receiving guidance during the neonatal period. Forty-six mothers were contacted and asked about the advice they had received and how they felt about the information provided. The mothers recruited for the study were divided into two groups, A (n=25) and B (n=21), according to the time elapsed since their participation in the project, that is, less than or equal to three months and more than three months, respectively. A Wilcoxom rank sum test did not show any statistically significant difference between the two groups (p>0.05). Guidance on the baby's oral hygiene, breastfeeding the baby exclusively until the sixth month, as well as the restrictions imposed on sugar intake were what the mothers remembered most. Recommendations concerning good arch development and the use of bottles were what mothers remembered least. Regarding infant oral health, it would be advisable to schedule prenatal and neonatal visits, with the second post-natal consultation no later than four months after childbirth. UNITERMS: Health promotion; Dental caries; Breastfeeding.egundo o paradigma atual de promoção de saúde, a atenção odontológica deve se iniciar ainda nos primeiros meses de vida ou então anteriormente ao nascimento, já que hábitos alimentares e de higiene bucal se estabelecem muito cedo. Avaliouse o grau de conhecimento e as atitudes das mães com relação à saúde bucal do bebê, após as mesmas terem recebido orientações no período neonatal (projeto "Odontopediatria no alojamento conjunto"/ UFG). Quarenta e seis mães com idades de 15 a 38 anos foram questionadas a respeito das orientações recebidas, bem como seu comportamento em relação às mesmas. Dividiu-se a casuística em dois grupos, A (n=25) e B (n=21), de acordo com o tempo decorrido após a implementação do projeto, ou seja, menor ou igual a três meses e maior que três meses, respectivamente. Frente às orientações recebidas (transmissibilidade da cárie dentária, hábitos alimentares, desenvolvimento das arcadas e higiene bucal), a análise de variância não mostrou diferenças estatisticamente significantes entre os dois grupos (p > 0,05), no que diz respeito ao conhecimento e atitudes das mães. As orientações de higiene bucal do bebê, de aleitamento materno exclusivo até seis meses e a restrição na ingestão de açúcar foram as mais lembradas pelas mães. Recomendações referentes à contribuição ao bom desenvolvimento das arcadas e às precauções quanto ao uso de mamadeiras foram menos recordadas. Considerando a saúde bucal do lactente, seria aconselhável que cuidadores sejam orientados nos períodos pré-e neonatal, sendo que a segunda consulta odontológica pós-nascimento deve idealmente ocorrer por volta do quarto mês de vida da criança.
