Dental Erosion

Abstract

SUMMARYThere is some evidence that dental erosion is steadily spreading. To diagnose erosion, dental professionals have to rely on clinical appearance, as there is no device available to detect it. Adequate preventive measures can only be initiated if the different risk factors and potential interactions between them are known. When substance loss, caused by erosive tooth wear, reaches a certain degree, oral rehabilitation becomes necessary. Prior to the most recent decade, the severely eroded dentition could only be rehabilitated by the provision of extensive crown and bridgework or removable dentures. As a result of the improvements in composite restorative materials and in adhesive techniques, it has become possible to rehabilitate eroded dentitions in a less invasive manner.

Noncarious Cervical Lesions Restored with Three Different Tooth-Colored Materials: Two-Year Results

“…Sclerotic, or vitreous dentin, is shiny and dark with a homogenic surface, is considerably tougher when probing, and contains denatured collagen, which significantly hinders the formation of adhesive interlocking. 7,8 The literature shows that the quality of adhesion to sclerotic dentin is weaker when compared to nonsclerotic dentin, as the conditioning of sclerotic dentin is unpredictable because of the higher degree of mineralization and almost complete obliteration of the dentinal tubules, resulting in a lower penetration of adhesives. 8,9 The hybrid layer (resin-reinforced dentin zone) is significantly thinner in sclerotic dentin when compared with normal dentin.…”

Restoration of Noncarious Cervical Lesions: When, Why, and How

“…In fact, the occurrence of this condition is steadily increasing [1–4]. According to the present literature available, it is not possible to determine a unique etiological factor, but there is a concern that it is a multifactorial condition [5–8]. These lesions can affect tooth sensitivity, plaque retention, caries incidence, structural integrity, and pulp vitality, and they present unique challenges for successful restoration [5–9].…”

Topical fluoride application is able to reduce acid susceptibility of restorative materials

“…Generally speaking, the strategy of the fluoride application is to render the tooth tissue more resistant against acid attacks 1) . In literature, a number of studies showed that fluoride application is able to reduce erosive substance loss, calcium release, and surface softening of enamel and dentine [2][3][4][5][6][7] .…”
