| Popis: | The aim of the study was to evaluate if there are significantly differences in immediate marginal adaptation of a self-adhesive flowable composite resin used in association with a universal bonding agent and to compare the sealing ability to a conventional flowable composite resin. Class V cavities were prepared on the buccal and lingual surfaces of eighteen molars and bicusps. The cavities were restore using a self-adhesive flowable composite resin (Vertise™ Flow, Kerr Dental), a conventional flowable composite resin (Neo Spectra™ ST Flow, Dentsply Sirona), and a universal adhesive system (Prime and Bond Active, Dentsply Sirona) applied in etch and rinse or self etch strategy. The teeeth were submersed in distilled water for 24 hours, then in 2% methilen blue solution for 24 hours. Buccal-lingual sections were obtained by cutting the teeth and were evaluated using an optic microscope. The microleakage at gingival and occlusal margins was assessed by dye penetration according to a 4 grade scale. There was no significantly different microleakage when using Vertise™ Flow in association with the universal bonding agent or without it. The use of Vertise™ Flow self-adhesive composite resin determined similar enamel and dentin microleakage, irrespective the use of a bonding system or the strategy of bonding application. Conventional flowable resin Neo Spectra™ ST used in association with the bonding agent lead to a significantly higher microleakage when comparing to self-adhesive composite resin Vertise™ Flow used in the same conditions.The association of a bonding agent applied in etch and rinse or self etch strategy and the conventional flowable resin Neo Spectra™ ST significantly decreases enamel and dentin microleakage. |
