Caries removal techniques: An update on relevant factors

Abstract

Introduction: Dental caries is a chronic infectious disease with a multifactorial etiology that leads to the destruction of the dental tissues.Objective: To analyze the literature on the influence of chemical-mechanical and conventional caries removal methods, as well as self-etching and wash-and-rinse adhesive systems on adhesion forces.Methodology: A compilation of articles published in the last 5 years was carried out using PubMed, Google Scholar and SCOPUS. Abstracts and full texts were identified that included information on factors influencing resin application: "papacarie", "rotatory", "adhesive", "self-etching", "etch and rinse".Results: The use of papacarie makes the dentin porous and irregular having a stronger bond. The traditional method shows the presence of smear smear affecting the bond between the adhesive and the dentin. Self-etching adhesives, by not performing the etching and rinsing step, can affect the bonding pattern on the enamel prisms. The increase to bond strength in etch-and-rinse adhesive systems is attributed to the increased porosity created in the enamel.Conclusions: Papacarie exhibits better bonding properties and higher surface energy compared to the conventional method. Self-etching adhesives exhibit lower bond strengths than etch-and-rinse adhesives, this is attributed to increased penetration of the adhesive into the tooth surface.
