In-Vitro Silanization of Dental Enamel to Prevent Demineralization

Introduction. Caries is a multifactorial disease that can negatively affect dental tissues through the demineralization process, which produces acids deriving from metabolism of carbohydrates. Some strategies to prevent this process have been proposed, such as topical fluoride application, resin-based restorations, pit and fissures sealers, infiltrated resins, vaccines, mouthwashes, several brushing techniques. Objective. To evaluate in vitro enamel hydrophobic modification method prevention against demineralization. Materials Methods. A descriptive comparative study was carried out. Thirty premolars extracted for orthodontic reasons were obtained, encapsulated epoxy resin, sectioned, sanded obtain specimens 3mm thickness. The samples pretreated with NaOCl EDTA, incubated 1 4% octadeyltrichlorosilane (OTS) or 3 6% octadecyltriethoxysilane (TEOS) 5min 8h. Subsequently, immersed citric acid 2 months. analyzed by their contact angle, infrared spectroscopy, scanning electron microscopy, atomic confocal force, before after treatment acid. Results. coated OTS 8h kept silanizing agent on surface months TEOS only effective at reaction time 5min. Conclusions. protects tooth acidic medium. results indicate 5min, makes it appropriate clinical practice.
