The Prevalence, Distribution and Expression of Noncarious Cervical Lesions (NCCL) in Permanent Dentition -
A non-carious cervical lesion ( NCCL) is defined as loss of dental hard tissue in the cervical part of the tooth, not caused by caries, multicausal and insufficiently clarified etiology. Identification of specific etiological factors NCCL is a key in making decisions about treatment. The authors conducted a study to evaluate the prevalence and distribution of noncarious cervical lesions in adults. Material and Methods: The sample of 210 respondents, were divided into three age groups. Clinical inspection has determined the distribution of NCCL within the respondents in relation to their age, teeth groups, vestibular and oral surfaces of the teeth, sides of the jaws and expression of NCCL according to the tooth wear Smith– Knight Index. Results: This research points to a very common finding NCCL within our respondents. Cervical lesions were diagnosed in 78.6% respondents in the first, 91.4% in the second and 97.2% in the third group. It has been shown that the number and expression of cervical lesions increases with age of respondents. Noncarious cervical lesions are usually the most visible on premolars, furthermore the first molars and canines, the second molars and then incisors. The minimum number of lesions were diagnosed in the third molars. Conclusion: Given the high prevalence of NCCL’s, there are reasonable grounds for introducing the tooth wear Index to the wider clinical practice, recording noncarious cervical lesions in dental records, creating specific prevention strategies and effective treatments.
