BACKGROUND: The purpose of the authors' in vivo investigation was to analyze the characteristics of @entity75 , or NCCLs, in adult @entity1 who had a high incidence of them. METHODS: The @entity1 pool consisted of a total of 57 @entity1 and 171 teeth (three teeth per @entity1 ), with one NCCL per tooth. The characteristics the authors evaluated were shape, dimensions, sensitivity, @entity1463 and occlusion. RESULTS: In terms of lesion characteristics, 91 percent of the lesions had axial depths of 1 to 2 millimeters, 49 percent had occlusogingival widths of 1 to 2 mm, 74 percent had an angular shape of 45 to 135 degrees, 76 percent had mild or moderate @entity1463 , and 73 percent had no or mild sensitivity. In terms of occlusion, 75 percent of teeth had an Angle Class I occlusion on the involved side, 60 percent had group function or mixed excursive guidance, 82 percent had wear facets, and 99 percent had Type 0 or I mobility. In terms of tooth location, 70 percent of NCCLs were on posterior teeth, 65 percent were on maxillary teeth, and 46 percent were on premolars. CONCLUSIONS: The evaluated NCCLs were found mainly to have small dimensions of depth and width (< 2 mm) and to be roughly right-angled in shape, and many had @entity1463 and low sensitivity. A majority of the dentitions studied had Class I occlusion, with group function, prevalent wear facets, and little or no mobility. @entity75 were more common with posterior maxillary teeth and premolars, especially first premolars, which had the highest prevalence of lesions. Older @entity1 were more likely to exhibit @entity75 , but no great difference in incidence was found between @entity1 and @entity1 . Clinical Implications. A knowledge of the NCCL characteristics and etiologic covariables aids in proper case selection for treatment, aids in selection of appropriate treatment protocols and improves assessment of prognosis.
