SAENZ MASIS, María Fernanda  e  MADRIGAL LOPEZ, Daniela. Buffer capacity of saliva and its relation to the prevalence of caries, with the intake of different commercial drinks. Odontología Vital [online]. 2019, n.31, pp.59-66. ISSN 1659-0775.

Nowadays the consumption of juices, and soft drinks, is very common in the children’s diet, they offer different flavours and a high content of sugar. In this study, an analysis of the buffer capacity of the saliva was made in view of the intake of different types of beverages considered healthy and unhealthy. Two types of instruments were used, a clinical test applied to 62 students to determine the prevalence of caries according to ICDAS and a second instrument that consists of a chart applied to the same 62 students with the purpose of analyzing the buffer capacity by taking the pH on intervals of 15, 35 and 45 minutes after drinking the beverages.

As a conclusion, it was obtained that for the drinks considered unhealthy, the pH took longer to neutralize, while the healthy drink achieved its neutralization faster, with a low prevalence of caries.
