Abstract

|
|
Incomplete removal of bacteria contaminated dentin or enamel associated with caries is a potential problem in restorative dentistry. Secondary or residual caries, pulpal inflammation and hypersensitivity may result from bacteria left after the initial preparation, especially if an adequate seal against microleakage is not obtained. A possible solution to eliminate residual bacteria left in a cavity preparation would be to treat the cavity with cavity disinfectant wash. But a potential problem with using a cavity disinfectant with dentin bonding agents could be their interference with the ability of the resin to bond to the tooth micromechanically.
The purpose of this study was to ecaluate the effect of 2% chlorhexidine containing cavity disinfectant(consepsis) on shear bond strength and microleakage of dentin bonding agents, Adper Scotchbond MultiPurpose. Adper Single Bond and Adper Prompt L-Pop. Sixty and sixty sound human third molar teeth, respectively, were used for shear bond strength and microleakage test. For experimental group, cavity disnfectant was applied before dentin bonding agents, and was not applied for the control group.
The result from the this study can be summarized as follows;
1. Use of 2% chlorhexidine containing cavity disinfectant(Consepsis) does not significantly affect the shear bond strength of dentin bonding agents.
2. Use of 2% chlorhexidine containing cavity disinfectant(Consepsis) dese significantly affect the microleakage of dentin bonding agents.
