Abstract
OBJECTIVES:
The aim of this study was to evaluate dentine permeability after brushing with Twin Lotus(®), Thai herbal toothpaste by comparing with Sensodyne Rapid Relief(®), a commercial desensitizing toothpaste, and also after artificial saliva (AS) immersion or citric acid challenge.
MATERIALS AND METHODS:
Dentine discs from human mandibular third molars were divided into three groups (n = 20) and brushed with either experimental toothpaste or water (control) for 2 min with an automated toothbrush. Then, 10 discs were immersed in AS, and the other 10 discs were immersed in 6% citric acid to simulate the conditions of the oral environment. The dentine permeability of each specimen was measured before brushing and after each treatment using a fluid filtration system. Morphological changes in the dentine were observed using scanning electron microscopy (SEM).
RESULTS:
Both toothpastes significantly reduced dentine permeability, and a crystalline precipitate was observed on the dentine surface under SEM observation. No significant difference was found between the two toothpaste groups with regard to dentine permeability after brushing and AS or acid immersion.
CONCLUSIONS:
The dentine permeability reduction caused by the two toothpastes did not differ after brushing or after AS or citric acid immersion.
