ABSTRACT
This study aimed to perform a comparative assessment of microleakage in Class V cavities among five different composite resins. For this purpose 100 fresh caries-free human permanent molars were randomly assigned to one of five groups (n=20). Clearfil Majesty Esthetic + Clearfil S3 Bond (Group I), TPH Spectrum + Xeno V (Group II), Gradia Direct Anterior + G Bond (GC) (Group III), Premise + Optibond All in One (Group IV) and Charisma + iBond (Group V) were applied and polymerized under LED. Specimens were varnished, immersed in 0.5% methylene and sectioned bucco-palatinally/lingually, and microleakage scores were determined.
Gingival and occlusal microleakage scores among groups were statistically significant (p<0.05) (p=0.043, p=0.005). Occlusal microleakage scores for Clearfil Majesty Esthetic and Premise were lower than in the other groups. Charisma had the highest microleakage scores, with no difference among the other groups (p>0.05).
In conclusion occlusal and gingival microleakage scores were satisfactory except for Charisma.
