Resumo

Este trabalho avaliou a ação dessensibilizante do cloreto de sódio (NaCl), popularmente conhecido como sal de cozinha, em 20 pacientes com hipersensibilidade dentinária de colo, selecionados das clínicas de periodontia da UNESP e UNIVAP de São José dos Campos - SP. Cada paciente utilizou a própria escova, cujas cerdas, ainda úmidas devido à escovação anterior, foram impregnadas com NaCl, procedendo a uma nova escovação noturna (Técnica de Bass) durante aproximadamente 10 segundos em cada dente selecionado. O período proposto foi de 4 semanas. Ao final de cada semana, os pacientes foram avaliados, por métodos subjetivos (questionários) e métodos objetivos (jatos de ar), quanto à resposta dolorosa. Os resultados demonstraram que houve diminuição significativa na hipersensibilidade dentinária.

Palavras-chave

Sensibilidade da dentina, cloreto de sódio.

Abstract

This work evaluates the pain-inhibiting action of sodium chloride (NaCl), traditionally know as cooking salt, on twenty patients with dentine neck hypersensitivity selected among Periodontic Clinic of the UNESP and UNIVAP in São José dos Campos, SP. Patients used their own toothbrushes with bristles still wet from previous brushing. In the treatment group, patients soaked with NaCl, their night brushing (Bass Technique) for about 10 seconds of each selected tooth. A 4-week period of assessment was suggested and, at the end of each week, patients were evaluated by both subjective means (using questionnaires) and objective methods (through assessment of pain in response to airjets). Our results reveal that NaCl application on the toothbrush significantly reduces dentine hypersensitivity.
