ABSTRACT
INTRODUCTION:
The aim of the study was to evaluate the in vitro microleakage of new flowable compomers in the class V cavities of primary teeth.METHODS:
Thirty freshly extracted, non-carious, primary molars without visible defects were used in this study. Class V cavities (n = 60), with the occlusal and cervical margins located in the enamel, were prepared on the buccal and lingual surfaces. The samples were randomly divided into 3 groups of 20 each. Group 1 restored with Twinky Star Flow (Voco, Cuxhaven, Germany), Group 2 restored with Dyract Flow (Dentsply, Konstanz, Germany) and Group 3 restored with R&D Series Nova Compomer Flow (Imicryl, Konya, Turkey) according to the manufacturer's instructions. After a thermocycling regimen of 1000 cycles between 5°C and 55°C, the samples were isolated, immersed in 0.5% basic fuchsine solution for 24 h at 37°C and sectioned longitudinally in a buccolingual direction. The sections were evaluated for values of microleakage with a stereomicroscope.RESULTS:
All materials showed microleakage but no statistically significant difference was observed among the groups (p>0.05). The highest microleakage score was observed in group II (1.65 ± 0.49) and group I (1.75 ± 0.44) at occlusal and gingival margins, respectively.CONCLUSIONS:
Flowable compomers showed insignificantly least amount of microleakage in class V cavities prepared on primary molars.
