Abstract
Background. In modern dental practice, there is a problem of complications after treatment of caries, such as the postoperative sensitivity of the tooth, formation of secondary caries, and caries complications in the form of pulpitis or periodontitis of the tooth. In addition, this problem exists despite the achievements in the production of high-quality composite filling materials, which are very popular among dentists worldwide. One of the problems that lead to complications after caries treatment is a violation of the integrity of the adhesive bond between the composite and the tooth tissue, which is manifested by a violation of the seal of restoration and the formation of a gap between the filling material and the tooth tissues. This in turn leads to the development of tooth sensitivity and the possibility of bacterial invasion between the filling material and the walls of the tooth, followed by the progression of the pathological process. In the scientific literature, there is evidence of the positive effect of preheating and vibration on the composite before its polymerization.
Aim. Additionally, the purpose of this study is to determine the effect of physical impact, such as heating and vibration, on the composite using ultrasound in order to improve the quality of the adhesive fixation of the composite filling material to the walls of the tooth.
Materials and methods. The study was conducted on the extracted teeth of patients. Based on this, we have proposed a method for the simultaneous thermo-vibration action on a non-polymerized composite directly in the formed tooth cavity to improve the physicochemical, including the adhesive, properties of light-curing composites.
Results of the study revealed a statistically significant positive effect of thermo-vibration on the composite, not only in comparison with the classical method of working with the composite at room temperature, but also with the method of preheating the composite in a furnace used for heating the composite.
