Caracterización fisicoquímica de la saliva de niños de temprana infancia que asisten al centro Infantil de cuidado diario Perpetuo Socorro

Abstract

Saliva is a key fluid in protecting the oral health particularly in children in early childhood, so it can be considered as a preventive factor in caries process. This essay was longitudinal, prospective, and non-experimental. The pH, salivary flow, and salivary buffer capacity were determined according target times in unstimulated saliva of 150 children in early childhood who attend “Perpetuo Socorro” daycare, were split up in three groups according to their age: (10 to 22 months), (23 to 35 months) y (36 to 48 months). Sampling was done in the morning, after lunch, and after a nap. Microsoft Excel and SPSS v.20 programs were used for the statistical analysis. The 80.44 percent of the population showed salivary pH normal parameters. Group one and two showed low flow and salivary buffer capacity values of 57.33 percent and 58 percent respectively and a 6.75 percent had critical salivary flow values while group three showed a normal value of 49.66 percent. Statistical analyzes were performed at a confidence interval of 95%. In Friedman’s test p=0,000 was obtained, with significant differences at different times of saliva collection, presence of a linear association was found with Pearson correlation p > 0,005 and no differences for salivary pH among the three groups were found with a direct correlation between the three variables and one-way correlation ANOVA; flow and salivary buffer capacity homogeneity were found between group one and two; although, group three differs from this result. The study population would be exposed to dental caries formation by low and critical value
