Risk Factors Associated with Non Carious Cervical Lesions at a Teaching Hospital.

OBJECTIVE: The purpose of this clinical study was to analyze the etiology, assess the factors associated with non carious cervical lesions and to determine the most commonly involved teeth and their inter/intra arch relations. METHODOLOGY: 100 patients with non carious cervical lesions (NCCL) were clinically examined and a questionnaire of associated factors to help determine the cause of the presence of the lesion was included in the assessment. The obtained data was statistically analyzed using descriptive statistics, frequency, Chi-square test and cross tabs to determine the relationship between the number of NCCL in groups and the associated factors. RESULTS: Sensitivity ( P= 0.471), aesthetic concern ( P= 0.077), diet concerns (P = 0.557), regurgitation ( P= 0.810), medical condition ( P= 0.344), nervous habits ( P= 0.799),? drug use ( P= 0.880), Unilateral chewing habits ( P= 0.159) were not associated with the presence of NCCL. However, parafunctional habits ( P= 0.039 ), right working side ( P= 0.012 ) were associated with increase in the number of NCCL. First premolars were found to be the most affected teeth and cross tabs suggested that if there was a lesion in the maxillary first premolar, the mandibular first premolar was also involved of the same side. CONCLUSION: Parafunctional habits do have association with NCCL. Premolars are the mostly affected teeth. If a premolar of maxillary arch is affected, it is most likely that the premolar of mandible on the same side will be affected.
