Relationship between erosive potential (salivary pH) and the most frequent fluid intake in a school lunch box in children from 3 to 6 years of the I.E.P “Mi lucero” Chorrillos district. Lima-Perú.

Abstract

Objective: The objective of this research was to determine the erosive potential of the most common liquids in a school lunchbox among children aged 3 to 6 years from I.E.P. “Mi Lucero,” Chorrillos district, through variations in salivary pH. Materials and Methods: This was an experimental, comparative, and longitudinal study. A total of 103 children aged 3 to 6 years with deciduous dentition, with and without dental caries, and with adequate OHI, were evaluated. Prior to the examination, teeth were brushed using the modified Stillman technique, and after one hour, baseline salivary pH was measured with a digital pH meter. Following the ingestion of liquids (Coca Cola, orange Frugos, and lemonade), salivary pH was measured at 5, 40, and 60 minutes. The data were analyzed using Student’s t-test with a significance level of p<0.05, revealing the greatest salivary pH drop at 5 minutes post-ingestion, particularly after drinking Coca Cola (pH 6.3). Recovery and stabilization were observed more rapidly with lemonade (pH 7) and orange Frugos (pH 7) at 40 minutes compared to the initial pH.

El objetivo de la investigación consiste en determinar el potencial erosivo de los líquidos más frecuentes en una lonchera escolar en niños de 3 a 6 años del I.E.P. “Mi Lucero” distrito de Chorrillos a través de las variaciones de pH salival. Material y Método: Es un estudio experimental, comparativo, y longitudinal. Se evaluaron 103 niños de ambos sexos de 3 a 6 años con dentición decidua; con y sin caries dental; con IHO adecuado, previo al exámen se realizó el cepillado dental con la técnica de Stillman modificado, luego de 1 hora se procedió a la medición del pH salival basal con el pHmetro digital, y después de beber los líquidos (Coca Cola, Frugos de naranja y limonada) se midió a los 5,40 y 60 minutos. Los datos obtenidos se analizaron mediante pruebas estadísticas de t Student con significancia de p< 0.05, revelando mayor caída del pH salival a los 5 minutos post ingesta, especialmente luego de beber Coca Cola (pH 6.3), observando recuperación y estabilización más rápida en la limonada (pH 7) y Frugos de naranja (pH 7) a los 40 minutos en comparación con el pH inicial.
