An interdisciplinary approach for the management of noncarious lesions

Abstract

Miller's class III gingival recession is a common entity observed in individuals, posing a difficult situation for the clinicians to treat. Large fenestration defects with cervical abrasion compromise the esthetics resulting in poor prognosis. Obtaining predictable and esthetic root coverage has become an integral part of periodontal therapy. The present case report describes a situation where class III gingival recession with cervical abrasion was seen in the lower central incisors. The patient was successfully treated with a combination of restorations (Filtek Z350® composite resin) to fill the defect, followed by fenestration procedure to increase the vestibular depth and subsequently with grafting procedure (soft tissue autograft with bovine-derived xenograft collagen [Bio-oss]). Though the results were not tangible esthetically, it was functionally successful as evidenced during the follow-up period.

Evaluation of Abfraction Lesions Restored with Three Dental Materials: A Comparative Study

“…The periodontium phenotypes, represented by the gingival and by the underlying osseous tissues, present a large variability and significantly different responses to injuries, and require specific treatment [63][64][65]. The treatment of cervical lesions can induce the occurrence of irritating lesions and chronic illness of the periodontium, especially when they are located at the level of the free gingiva, due to the technique applied in the isolation of the prosthetic field in filling the lesions and in the inappropriateness of the marginal sealing technique [66,67]. In this study, the abfraction restorations were carried out without the use of a gingival retraction cord or rubber dam on account of the fact that the cervical margins of the abfraction lesions were located at the level of the free gingival margin, so the structure of the marginal periodontium was not damaged.…”

The Wear Performance of Glazed and Polished Full Contour Zirconia

“…Loss of tooth structure which is not caused by caries can also be qualified as abrasion, erosion, attrition or abfraction, with attrition being produced by contact between teeth, or between teeth and restorative materials during mastication or parafunctional habits (25). The amount of dental structure lost by the effects of attrition against restorative materials is only one of many issues related to wear such as chewing frequency, dietary abrasiveness, surface roughness, or intraoral oral composition, and which should be considered in future studies (26).…”
