Apparatus and methods for polymerization of composite resins have been seeking to improve the restorations properties. This study aimed to assess the knowledge of dentists before the use of light curing units. Data collection was done through a questionnaire, administered to 34 dentists from course IMED Restorative Dentistry Specialization in the years 2015 and 2016. The results showed that 34 of the dentists interviewed , 35.30% used Gnatus brand, 23.53% RadiCall, and 20.58% Schuster. As for the year 35.3% had photopolymerizer the year 2015, 17.64% year 2010 and 11.77% year 2014. Regarding the type of lamp used, 91.14% used Led, 5,38% halogen and 2 94% Led and halogen. Regarding the consequences of polymerization shrinkage, 23.52% of dentists related postoperative sensitivity, marginal leakage, recurrent decay and enamel crack as consequences, 20.58% considered the microleakage the only consequence and 23, 52% only postoperative sensitivity. Of the total sample 29.4% said to reduce the stress of polymerization shrinkage used other curing techniques, 17.64% ramp type, 20.58% step type. It can be observed that 70.56% of respondents reported that less than half of the cases occurred sensitivity incidences after the restorative treatment, 20.58% never observed postoperative sensitivity, and 8.82% just in half of the cases. It was possible to observe the most types and brands of equipment used by professionals, and it was noted still a lack in the knowledge from professionals about the polymerization shrinkage consequences.
