The surface effects of erosion and abrasion on dentine with and without a protective layer

Abstract

Objective The aim of this in situ study was to investigate with four imaging modalities whether covering dentine with adhesive resins could protect against erosion from acids. The objectives were to observe and quantify the effects of acids and the soft tissues, especially the tongue, on dentine and the bonding agents using four assessment techniques: qualitative assessment with SEM, surface roughness and thickness of resin with the TSM and volume loss with the laser profilometer. Design An in situ investigation using extracted dentine sections embedded in splints held on the palate of 10 volunteers. The dentine sections were protected by two resins and subjected to a tooth wear regime. Results Both Seal and Protect and Opitbond Solo protected the tooth surfaces from a tooth wear regime. There were no statistical differences between the control surfaces and those protected with dentine bonding agents for resin thickness, roughness and profilometry. The appearance of the slabs under both confocal and SEM showed that the material remained in place despite a vigorous wear regime and therefore protected the tooth surface. Conclusions For patients with uncontrolled erosion or tooth wear, applying a dentine bonding agent to exposed dentine is a practical option to prevent further damage.

Protective Effect of Adhesive Systems associated with Neodymium-doped Yttrium Aluminum Garnet Laser on Enamel Erosive/Abrasive Wear

“…The application of conventional and self-etching adhesive systems for protection against dentin wear was previously tested, and decreased erosive and abrasive wear was found. 17 The use of adhesives to reduce enamel dissolution after carious acid challenge has also been tested. 18 The adhesives tested in our study were chosen because they are self-etching and do not require prior application of a strong acid for getting retention, which would result in an additional wear on the already eroded surface, thus being more aggressive.…”

“…[15][16][17] Another study has applied the adhesive over the enamel, and its results showed decreased dissolution of enamel after acid challenge. 18 The treatment of cavity walls with Nd:YAG laser has been investigated to improve the bond strength.…”

Influence of prophylaxis paste treatment on the abrasive wear of surface sealants

“…This method of quantification has been applied for these purposes in different other studies [17,29,30]. For the here used profilometer, a lower limit of measurements of 0.105 µm has been determined, allowing an exact quantification of even the lowest wear (0.82 µm) found in this study.…”

Tooth Wear, Etiology, Diagnosis and Its Management in Elderly: A Literature Review

“…39 Composite may be placed temporarily or overexposed areas while dentin bonding agents may be effective in reducing sensitivity and preventing further damage. 40 Definitive restorative procedures should not be performed without identification of etiological factors in conjunction with adequate preventive measures.…”
