Abstract

The purpose of this study was to evaluate influence of etching ability of one-step self-etch adhesives on bonding to non-carious cervical sclerotic lesion. Forty-eight human maxillary premolars with and without natural non-carious cervical sclerotic lesions at buccal surfaces were used in this study. Artificial wedge-shaped lesions were prepared in sound premolars. All lesions were bonded with Bond Force (BF; pH=2.3) or G-Bond Plus (GBA; pH=1.5) according to the manufacturers' instructions. After water storage for 24 hours at 37 degrees C, bonded specimens were subjected to microtensile bond test to measure bond strength to the gingival wall in each lesion. The mu TBS of BF to the natural lesion was significantly lower than that of artificial lesion (p0.05). There was no difference in mu TBS to artificial lesion between these two adhesives, however in case of non-carious cervical sclerotic lesion, the mu TBS of GBA was statistically higher than that of BF.
