Variaciones en el grado de hipersensibilidad dentinaria producido con un sistema de pulido radicular

Abstract

Randomised longitudinal parallel clinical study aiming to asses the dentinal hipersensitivity by means of different stimuli comparing a tooth polishing system (Prophy-Jet) using four different abrassive powders. Methods and Materials: 136 subjets were selectd without hipersensitivy symptoms or any other dental, périodontal or system pathology. These patients were divided into four group and each was assigned to a different air-polishing system based on the degree of abrasiveness. Afther a dental prophylaxis the airpolishing was carried out with the propy-jet system and patients were recalled at intervals 2 days and 2 weeks in order to asses the degree of hipersensitivity. Results: A higher degreee of dentinal hipersensitivity was observer with the abrasives sodium bicarbonate and calcium carbonate. The other two abrasives showed hardly any reaction. Conclusions The degree of dentinal hipersensitivity after a tooth polishing depends on the abrasiveness of the powder used. Sodium bicarbonate demonstrates a high prevalence of dentinal hipersensitivity.
