Effect of resin photopolymerization on primary teeth pulpal temperature change.

Purpose: The polymerization of restorative materials has the potential to increase pulpal temperature and may result in damage to the health of pulpal tissue. The aim of this study is to investigate the pulpal temperature change of primary teeth with two LED light-curing units (Valo Cordless®, EliparTM DeepCure-S) and three restorative groups (Filtek™ Bulk Fill Flowable, Filtek™ Z250 Universal Restorative and empty cavity) by using a microcirculation model. Material and Methods: Ten sound human maxillary second primary molars were used. Standardized Class V cavity preparations were performed with a dentin thickness of 1 mm and restorative groups were cured with LED light-curing units. The highest temperature point in the pulp chamber was recorded. A repeated measures ANOVA and paired samples t-test were used for analysis of the data (𝑝
