Abstract
Objectives.The aim of this study was to investigate the effect on the acid resistance of enamel after use dentifrice containing bamboo salt.
Methods.Incipient caries lesion of bovine enamel was formed in pH 5.0 lactate carbopol buffer system for 60 hours. Then, experiment groups were divided (n=12/group) into four groups without statistical difference of Vickers hardness number (VHN) and were carried out under pH cycling model for 20 days as follows; fluoride free dentifrice (negative control), 1,000 ppm NaF dentifrice (positive control), 1,100 ppm NaF dentifrice (P&G Crest Cavity Protection) and 3.0% bamboo salt with 1,000 ppm NaF dentifrice (test dentifrice). Then, all specimens were immersed in acid solution which used incipient caries formation for 60 hours. Mineral loss value (?Z:vol%ㆍμm) and lesion depth (Ld:μm) of specimens were assessed by transversal microradiography (TMR).
Results.After chemical pH cycling, the ?Z of test dentifrice showed lower value than other groups but there was no significant difference among groups. The Ld of test dentifrice (61.59±6.58), P&G Crest Cavity Protection (64.56±6.31) and positive control (67.94±8.46) showed statistically significant lower than negative control (74.68±10.62) (p＜0.01). After acid treatment, ?Z of test dentifrice (2,403.62±448.10), P&G Crest Cavity Protection (2,459.24±412.22) and positive control (2,782.54±535.12) showed statistically significant lower than negative control (3,421.45±582.80)(p＜0.001). Also, Ld of test dentifrice (66.51±9.86), P&G Crest Cavity Protection (69.43±10.23) and positive control (79.69±14.59) showed statistically significant lower than negative control (113.41±9.65)(p＜0.001).
Conclusions.The dentifrice containing NaF and bamboo salt showed acid resistance effect, thus it could be useful agent for prevention of dental caries.
