ASSOCIATION BETWEEN DENTAL CARIES WITH FLOW AND VISCOSITY OF SALIVA IN SCHOLARS FROM BUCARAMANGA, COLOMBIA
Objective: to determine the association between dental caries with the viscosity, the pH and the saliva flew in scholars from Bucaramanga, Colombia.Methods: an analytical cross sectional study was carried out with 90 children in which socio-demographic characteristics, diet, health condition, oral hygiene, viscosity, pH and saliva flow were collected as explanatory variables and the presence of dental caries as dependent one. In the analysis, summary measures were calculated according to the nature of each variable. For univariate statistical analysis summary measures were calculated according to the nature of the variables. For bivariate chi-square test and Fisher exact test for qualitative variables and Student t test or Wilcoxon rank test for quantitative variables was applied. For binomial regression multivariate analysis was applied and Prevalence Ratios (PR) and confidence intervals of 95% (CI 95%) were calculated.Results: it was found that being over eight years [PR 1.4 CI 95% 1.3 - 1.4], having an abnormal salivary flow [PR 1.3 CI 95% 1.2 - 1.3] and abnormal salivary viscosity [PR 1.3 CI 95% 1.2 - 1.3] were statistically significantly associated with dental caries.Conclusion: decreased salivary flow and increased viscosity of saliva were associated with the presence of dental caries in the school population evaluated. It is important to consider these criteria to analyze the risk to dental caries.Objetivo: determinar la asociación de la caries dental con la viscosidad, el pH y el flujo salival en escolares de Bucaramanga, Colombia.Materiales y métodos: se realizó un estudio observacional analítico de corte transversal en 90 escolares, en los que se recolectaron las características sociodemográficas, dieta, condición de salud, higiene bucal, viscosidad, pH y flujo salival como variables explicativas y la presencia de caries dental como variable de salida. Para el análisis estadístico univariado se calcularon medidas de resumen según la naturaleza de las variables. Para el bivariado se aplicó test de chi cuadrado y test exacto de Fisher para las variables cualitativas y prueba t de Student o test de rangos de Wilcoxon para las cuantitativas. Para el análisis multivariado se aplicó regresión binomial y se calcularon las Razones de Prevalencia (RP) y sus intervalos de confianza del 95% (IC 95%).Resultados: ser mayor de 8 años [RP 1,4 IC 95% 1,3 - 1,4], tener un flujo salival anormal [RP 1,3 IC 95% 1,2 - 1,3] y una viscosidad salival anormal [RP 1,3 IC 95% 1,2 - 1,3] se asociaron de manera estadísticamente significativa con la caries dental.Conclusión: el flujo salival disminuido y la viscosidad aumentada de la saliva se asocian con la presencia de caries dental en la población de escolares evaluados. Es importante considerar estos criterios para analizar el riesgo a caries dental.[Suárez SP, Prieto MT, Otero DC, Ojeda WA, Concha SC.
