Abstract
Background/Aim: The aim of this study was to examine the
microleakage values after restoring the prepared Class II box cavities
using two different composite resins with three different layering methods
and polymerizing them with five different LED light devices. Material and
Methods: Class II box cavities were prepared in 150 extracted mandibular
molars. Nanoceramic composite resin (Ceram.x SphereTEC one universal
A2, Dentsply, Germany) and bulk fill composite resin (SDR flow+ A2,
Dentsply, Germany) were used for the restoration of the cavities. Teeth were
restored with three different layering methods (bulk fill, horizontal layering,
and centripetal buildup technique) and five different LED light devices
[(Smartlite Focus, Dentsply, USA), (Led.E, Woodpecker, China), (Valo
Cordless, Ultradent, USA), (Bluephase N, Ivoclar Vivadent, Liechtenstein),
(D-Light Pro (GC, USA)] and then subjected to microleakage analysis.
Kruskal Wallis and Mann Whitney U test were used for statistical analysis.
Th e data was evaluated under p<0.005 significant level. Results: Using
different layering methods did not affect microleakage scores statistically
(p=0.7683). Applying bulk-fill composite resin with 2 mm horizontal
layers or using the centripetal buildup technique did not show significant
differences in microleakage. Second- and third-generation light devices
demonstrated no statistical difference in microleakage (p=0.9075).
Conclusions: Using different layering methods and different curing units did
not make any difference in microleakage.
