Effect of Two Different Cavity Disinfectants on Microleakage in Class II Cavities Restored with Composite Using Eighth Gen Bonding Agent - An Invitro Study

Dr Uday Kamath | Dr. Trupti Shetty

Abstract: Aim: The aim of the study was to determine and compare the effect of two disinfectants (2 % chlorhexidine and 19 % EDTA) on gingival microleakage in class II composite restoration using eighth generation bonding agent. Materials and method: Class II cavities were prepared on mesial and distal surfaces of 45 non-carious mandibular molars, resulting in total 90 cavities. All the 90 cavities were rinsed with distilled water and dried with a blast of compressor air. Each 15 samples were assigned to the control group and into two experimental groups. Group I samples were applied with 2 % chlorhexidine (Consepsis, Ultra dent) and Group II samples were applied with 19 % EDTA (File-Eze Ultra dent, USA). cavity disinfectants were rinsed & dried, dental etch was applied and rinsed off and a coat of G-Premio bond was applied, samples were cured and restored with G-aenial posterior composite. Microleakage was evaluated at the gingival margin using dye penetration method. The sections were examined using stereomicroscope (X30) is scored on a scale of 0-3 is data analyzed using Chi-square test. Results & Conclusion: Group I samples disinfected with 2 % CHLORHEXIDINE showed a least microleakage when compared to other two groups.
