Abstract

dentistry, either restorative dentistry or prosthesis, is microleakage. Several efforts have been undertaken to find out ways to eliminate or reduce problem. This in vitro study compares the microleakage between incremental and bulk technique in compsite build-up, using clear fil-photo core light cure.
Subjects and Methods:Twenty human premolar teeth with no caries and fractures were selected. For each tooth, 2 class II boxes were prepared and the teeth were divided randomly into two groups, and microleakage was evaluated on lingual and buccal sides following incremental and bulk techniques. The tooth were thermocycled (1000 cycles 5/55ºC) and immersed in 2% basic fushin for 24 hr, then sectioned mesiodistaly with a diamond disk. Dye penetration was examined using clearfil photo core light cure  stereomicroscope and scored according to specific criteria.
Result: There wasno significant difference between both groups and a mean of 76% grade IV microleakage was seen.
Conclution: According to low bond strength and high microleakage, Clearfil Photo Core-Light Cure not recommended as composite
