Non-Carious Cervical Lesion (NCCL) is the loss of hard tooth tissue at the cement-enamel junction not caused by caries and it was categorized in V-shape and saucer-shape according to the shape of the lesion on the plat surface. NCCLs often occurred on the buccal or labial surfaces of the teeth, especially the first premolars [1]. The tendency of distribution of NCCLs which maxillary teeth were ...

BACKGROUND The objective of this study was to determine the prevalence and severity of general tooth wear (GTW), i.e. tooth wear irrespective of etiology and erosive tooth wear (ETW), i.e. tooth wear predominantly due to erosion; and also to investigate the relationship between ETW and dental caries experience in 16-year-old adolescents in Kuantan, Malaysia. METHODS A multi-staged cluster sam...

Pathological, non-carious loss of tooth tissue is an increasing problem to the dental profession, with young individuals especially at risk. This paper provides an overview of the problem with an emphasis on the possible causes, particularly those factors which may account for the increased incidence. The clinical appearance produced by the various aetiological factors is discussed and recommen...

OBJECTIVES The aim of this study was to investigate the effects of erosion and toothbrush abrasion on different restorative materials and human enamel. METHODS Human enamel and 5 kinds of tooth-colored restorative materials were used. The restorative materials included three composite resins (Filtek Silorane, Tetric EvoCeram, and Tetric EvoFlow), a polyacid-modified composite (Dyract Extra), ...

Non-carious cervical tooth lesions for many decades were attributed to the effects of abrasion and erosion mainly through toothbrush trauma, abrasive toothpaste, and erosive acids. However, though the above may be involved, more recently a biomechanical theory for the formation of these lesions has arisen, and the term abfraction was coined. The aim of this study was to investigate the biomecha...
