Abstract:
Aims
To compare the marginal integrity of bulk fill flowable composite restorations and glass ionomer restorations in carious cervical lesions.
Methods and Material:
Sixty-three patients with carious class v cavities were selected from the clinic of Conservative Dentistry Department, Faculty of Dentistry, Cairo University. Patients were divided into three groups according to the restorations: group1: bulk fill flowable composite (Filtek ™ Flowable), group 2: high viscosity glass ionomer (ketac ™ Universal) and group3 (control group): Resin modified glass ionomer (ketac ™ Nano),. Conservative class v cavities were prepared by one operator. Randomization was done to allocate patients into groups. Restorations were evaluated at baseline, 3 months, 6 months and 12 months by USPHS criteria. Statistical analysis was done using Student-t test, Chi-square test and McNemar test where significance level was set at P ≤ 0.05.
Results:
Data were analyzed using Chi-square test to compare the frequency of USPHS scores of marginal integrity between restorative materials at each evaluation time. A significant difference was found between bulk fill flowable composite group and high viscosity glass ionomer group after 12 months (P=0.016) with Alfa scores were higher in bulk fill flowable composite group.
Conclusions:
Based on the data obtained in this study, bulk fill flowable composite showed better marginal adaptation than other groups after 12 months follow-up period.
