Abstract

Objective: To evaluate and compare the effect of bulk and layering composite filling techniques on the gingival microleakage in class II cavity.

Materials and methods: Standardized 60 class II cavities were prepared in the proximal surfaces of thirty extracted non caries permanent molars and randomly were divided into two main groups A and B each composed of 30 cavities, for group (A) the gingival floor on mesial side was prepared one mm above the CEJ and for group (B) one mm below the CEJ, then each main group was subdivided into three subgroups (n=10 cavities) according to the composite placement technique: 1) bulk, 2) horizontal, 3) oblique. The specimens were immersed in a solution of 2% methylene blue dye for 24 hours. The microleakage scores (0 to 3) were obtained from the cervical surface and the cervical microleakage was analyzed with a stereomicroscope.

Results: The gingival dye penetration increased when the gingival floor was below the CEJ. The microleakage is increased with bulk followed by horizontal and oblique.

Conclusion: This study predicts that the oblique layering composite filling technique of class II is betters then the other techniques when the gingival floor is above and below the CEJ.

Keywords: Gingival dye microleakage, Nano-hybrid resin based composite, bulk placement techniques, incremental, placement techniques.
