Abstract
BACKGROUND: Dental caries is the most common disease of the oral cavity, which can usually be treated by direct composite restoration.
AIM: To assess the quality of the marginal fit of adhesive systems and photocomposites to the hard tissues of the tooth.
MATERIALS AND METHODS: A scanning electron microscopic study was conducted with 30 restorations on teeth previously removed for medical reasons using a 7th-generation adhesive system from the universal group of various manufacturers and composite materials. The experiment included Tetric N-Bond Universal (Ivoclar Vivadent), Prime&Bond Universal (Dentsply Sirona), OptiBond Universal (Kerr), and composite materials (OptiShade, сeram.х® SphereTec, and Tetric N-Ceram). All of these adhesives can be used with any enamel and dentin conditioning technique or with dual-curing composites; thus, their use is relevant in orthopedic dentistry. Teeth sections were made with restorations and scanning electron microscopy was performed.
RESULTS: The self-etching adhesives of the universal group produced different results after studying the electron diffraction patterns of the teeth sections with restorations. The OptiBond Universal (Kerr) adhesive system had the best marginal fit, followed by Tetric N-Bond Universal (Ivoclar Vivadent) and Prime & Bond Universal (Dentsply Sirona). A clinical case of restoration with a combination of class 5 and 3 cavities according to Black was represented by the OptiShade material.
CONCLUSION: A violation of the marginal fit of the material in the zone of contact with the hard tissues of the tooth was noted in 60% of the cases when using the composite material Ceram.x® SphereTec (Dentsply Sirona) and the adhesive Prime&Bond Universal; 20% — Tetric N-Ceram (Ivoclar Vivadent) and Prime&Bond Universal adhesive; in 10% — composite OptiShade (Kerr) and adhesive OptiBond Universal (Kerr). The adhesive should be applied with a brush.
