EVALUATION OF MICRO LEAKAGE IN COMPOSITES WITH NEWER DENTIN BONDING SYSTEMS BY DIRECT TECHNIQUE IN CLASS V CAVITIES: AN IN-VITRO FLUORESCENT DYE PENETRATION STUDY
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2015, Vol 6, Issue 2
Abstract
The objective of this study is to evaluate the micro leakage of class V lesions restored with composite material (Tetric Ceram) using one total etch bonding system and two self etch bonding systems using fluorescent dye penetration technique. Class V cavity were prepared on forty five extracted intact human molars. The teeth were divided randomly and equally into one control group and two experimental groups. In Control group Conventional etching was carried out with 37 % phosphoric acid (Total Etch) and bonded with Excite DSC. In Experimental groups Group 1- Self etching primer (AdheSE) was applied and cured: Group 2 –Self etching primer (Uni fil Bond) was applied and cured. All the 45 teeth were restored with Tetric Ceram. The specimens were immersed in Rhodamine 6G for 24 hours. Longitudinal sections were prepared and were subjected for microscopic evaluation. Results were statistically analyzed using ANOVA and Multiple comparison tests. The study showed that both the self etching primers showed significantly lesser micro leakage when compared to the total etch bonding system. Self-etching dentin bonding systems (Uni fil Bond and AdheSE) gave the better results in terms of less micro leakage when compared to the total – etch dentin bonding system when used with composites.
