Eficacia de una medida preventiva para el niño con riesgo cariogénico asociada a la estabilidad de pH salival

摘要

Saliva is an etiological factor of caries. It acts stabilizing pH by its concentration of carbonates and phosphates. When the oral hygiene is deficient, pH becomes acid and optimal for the demineralization of teeth surfaces. If a diet rich in sugars and flour predominates, they become more acid and the risk of caries beginning is imminent. To determinate the behavior of salivary pH and demonstrate the effectiveness of the brushing as a low cost, efficient, easy application prevention measure, in children with cariogenic risk, samples of saliva of 44 children between 6 and 8 were taken, from San Martin de Porres district, before and after breakfast and analyzed with a potentiometer. GROUP 1: with old bacterial plaque (without previous tooth brashing) and GROUP 2: with recent bacterial plaque (with previous tooth brushing). According to “t” test analysis, the variation of pH salivary in both groups, before and after foods was statistically significant (p=0.000) but when comparing it between both groups 1 and 2, statistically significant differences did not exist. The removal of old and recent bacterial plaque is an essential preventive measure that is not related to the variation of pH salivary.
