Prevalência de cárie em escolares da zona rural de Indaiabira, Minas Gerais, Brasil / Caries prevalence among students in the rural area of Indaiabira, Minas Gerais, Brazil

O agravo que mais frequentemente afeta a saúde bucal da população é a cárie dentária, considerada um problema de saúde pública. Este trabalho objetivou conhecer a experiência de cárie entre escolares do município de Indaiabira-MG, visando subsidiar o planejamento de ações de promoção, prevenção e restauração da saúde bucal dessa população. Participaram os escolares residentes na zona rural, na faixa etária de 5 a 14 anos, sendo os dados colhidos nos prontuários odontológicos com autorização prévia da Secretaria Municipal de Saúde. Foram avaliados 637 escolares, 53,5% eram do sexo masculino. Estavam livres de cárie 242 crianças, 38% do total avaliado. O índice ceo para a idade de 5 anos foi de 4,25 (±3,219), e o CPOD para as idades de 12 e 14 anos foi respectivamente 4,19 (±2,721) e 4,86 (±2,92) com grande participação do componente cariado e necessidade de tratamento restaurador. É importante que se faça a intervenção nas idades iniciais, buscando prevenir a instalação da doença e de suas consequências na população adulta e idosa.

The disorder that most often affects the oral health of the population is tooth decay, which is considered a public health problem. This study focused on dental caries experience among school children of Indaiabira, MG in order to support the planning of health promotion, prevention, and restoration of the oral health of this population. The participants were children, ages 5-14 years, living in the rural area. Data was gathered from the dental records with the prior permission of the Municipal Health Department. A total of 637 students were evaluated, 53.5% males, and 242 were caries-free, 38% of the total assessed. The DMF index for 5-yearolds was 4.25 (± 3.219) and the DMFT at ages 12 and 14 years respectively was 4.19 (± 2.721) and 4.86 (± 2.92), with a large proportion of decayed teeth and the need for restorative treatment. It is important to intervene at an early age to try to prevent the onset of this illness and its consequences in the adult and elderly populations.

Susceptibilidade microbiana de bactérias e fungos frente ao extrato de Psidium guajara L: avaliação in vitro / Microbial susceptibility of bacteria and fungi against extracts of Psidium guajava L: in vitro evaluation

Aim: The present study aimed to evaluate the in vitro antimicrobial activity of hydroalcoholic and aqueous extracts from leaves of P. guajava on four bacterial and two fungal samples to determine the range of minimum inhibitory concentration of the extracts. Material and Methods: The antimicrobial activity of extracts of different polarities was compared using the agar dilution method. Differences in susceptibilityto the active ingredient could be observed. Results: The results showed that the hydroalcoholic extract wasactive against Escherichia coli (1024 ìg/ml) and Bacillus cereus (900 ìg/ml). The aqueous extract showedno antimicrobial activity. Conclusions: Despite demonstrating antimicrobial efficiency, the P. guajava extractmay be insufficient or may require a higher concentration to be fully effective.
