Abstract
Purpose: The aim of this in vitro study was to evaluate the effects of three restorative materials and chlorhexidine digluconate
(CHX) pretreatment on microleakage in Class V cavities.
Materials and Methods: Thirty freshly extracted sound human molars were cleaned and stored in distilled water. Sixty standard
Class V cavities were prepared on gingival 1/3 of buccal and lingual surfaces of each tooth. Teeth were randomly assigned into 3
groups corresponding to the selected restorative material (Fuji II LC Capsule/FC, GC; Beautifil Flow Plus/BF, Shofu; and GrandioSo
Flow/GF, VOCO). Lingual cavities were pre-treated with CHX (Cavity Cleanser, Bisco). The cavities were restored according to
manufacturer’s instructions using the materials’ own adhesive systems. Teeth were stored in distilled water (24°C) for 6 months
for aging. Specimens were immersed in 2% methylene blue solution for 1 h and sectioned longitudinally in buccolingual direction.
Occlusal/gingival margins were examined for dye penetration and scored under x8 and x20 magnification using stereomicroscope
(Leica MZ7.5, Leica Microsystems). Statistical analysis was performed using chi-square test with a significance level of p<0.05.
Results: There was no statistically significant difference between the amount of microleakage of GF, FC and BF restorations in
CHX-treated and untreated cavities (p>0.05). CHX pretreatment did not result in a significant difference between microleakage
values in gingival and occlusal margins of cavities restored with different materials (p>0.05).
Conclusions: Application of CHX as cavity cleaner has no effect on the microleakage in Class V cavities restored with giomer, glass
ionomer, and resin composites.
