EFICACIA DE UNA CREMA DENTAL PARA DIENTES SENSIBLES CON CITRATO DE POTASIO AL 5,6% Y FLUORURO DE SODIO AL 0,3%: ENSAYO CLÍNICO ALEATORIZADO CONTROLADO 1 EFFICACY OF A DENTIFRICE FOR DENTINE HYPERSENSITIVITY CONTAINING 5.6% POTASSIUM CITRATE AND 0.3% SODIUM FLUORIDE: A RANDOMIZED CLINICAL CONTROLLED TRIAL 1

Introduction: potassium and fluoride salts have been used for the treatment of dentine hypersensitivity. The objective of this study was to determine the efficacy of a tooth paste with 5.6% of potassium citrate and 0.3% of sodium fluoride for the treatment of dentine hypersensitivity. Methods: a randomized sample of 100 people, male and female from the Valle de Aburra, older than 18 years of age, with dentine hypersensitivity and who met the inclusion criteria was selected. A randomized triple blind clinical trial was designed, using a control group (placebo), and an experimental group (tooth paste for sensitive teeth). The subjects were given a questionnaire in which they rated the intensity of the pain using the visual analogical scale before the intervention; next, a tooth was selected in each person and subjected to a thermal stimulus test and constant pressure contact test,
