pH Salival, Capacidad Buffer, Proteínas Totales y Flujo Salival en Pacientes Hipertensos Controlados Usuarios de Diuréticos

introduction: hypertension (ht) is a cardiovascular disease with a high prevalence around the world. in chile at year 2010 it reached 26.9% of the population. objective: to determine salivary ph, buffering capacity, total proteins and salivary flow in controlled hypertensive diuretic users and a group without systemic diseases. methods: 14 samples of unstimulated saliva of patients with hypertension treated with diuretics and 10 samples of unstimulated saliva of people without systemic diseases and not taking medication were analyzed. ph, salivary buffering, salivary flow and total protein were determined in both groups. results: the figures for the treated ht patients were as follows: ph: 6.83, buffer capacity: 4.86, salivary flow: 0.55 ml / min and total salivary proteins: 1.09 g / dl. for those without systemic diseases the results were: ph: 6,88, buffer capacity: 4,25, saliva flow: 1.8 ml / min and total salivary protein: 0.29 g / dl. no association was found between salivary flow (rs = 0.425), buffering capacity (rs = 0.283) and protein concentration (rs = 0.245) with the diuretic dose (p > 0.05). statistically significant differences were found in salivary flow and total salivary protein concentration between the group with hypertension and without. (u mann-wthitney p > 0.005). no statistically significant differences in salivary ph and buffering capacity were found among the study groups (u mann-wthitney > 0.005). conclusion: patients with hypertension and treated with diuretics have a decreased salivary flow and an increased total protein concentration while ph and buffer capacity remained normal.
