- Abstract
Objective: To assess the effect of different enamel preparations and the role of bonding agent on microleakage of pits and fissure sealants. Methods: A total of 40 caries-free extracted human premolar teeth were divided into four groups according to fissure preparation: (a) prophylaxis (b) air polishing (c) air abrasion (d) mechanical preparation with ¼ round bur. All fissures were acid-etched and each of the group was subdivided into 2 subgroups with bonding agent applied in one group before placement of the sealant as opposed to direct placement of the sealant in the other group. Following thermocycling, microleakage was tested by staining with 0.5% acridine orange dye. After sectioning, teeth were examined and photographed in a fluorescent microscope. Chi square tests were used for statistical analysis. Results: Microleakage was significantly reduced with mechanical preparation compared to prophylaxis group. Air abrasion and air polishing showed nonsignificant improvement in microleakage as compared to prophylaxis group. Application of bonding agent caused significantly reduction in microleakage only with respect to prophylaxis group. Conclusions: Minimally invasive and invasive methods of enamel preparation cause reduction in microleakage in pit and fissure sealants. Application of a bonding agent can reduce microleakage of a sealant resulting in their long term retention when simpler procedures like prophylaxis are indicated.
