Abstract

Background. The factors that induce the formation of noncarious lesions are non understood fully, particularly those that are related to occlusal aspects. This study was evaluated the prevalence of noncarious cervical lesions in adults and their assosication with occlusal aspects. Methods. This study examined 70 people (35 men and 35 women) aged 25 to 45 years to determine the presence and type of noncarious cervical lesions, wear facets, tooth contacts in maximal intercuspal position, and lateral and protrusive movements. The assessment involved a questionnaire and clinical examination. Results. Among the teeth this study evaluated, 17.23 percent had cervical lesions, 80.23 percent of which had wear facet (P<.01). This study found a significant difference between the prevalence of noncarious lesions and the presence of wear facets (P=.0484). Conclusion. The study found that cervical lesions were related significantly to wear facets. these findings strengthen evidence for the role of occlusal forces as an etiologic factor for noncarious lesions Key words.
