Prevalence and Related Risk Factors of Noncarious Cervical Lesions
Objectives: The loss of cervical tooth structure through processes unrelated to caries is an increasingly common clinical finding, with prevalence rates as high as 85% in some populations. Despite this, there is still no consensus of the mechanism and factors involved in the etiology and progression of noncarious cervical lesions (NCCLs). The two-fold purpose of our study was to: 1) measure the prevalence of NCCLs in an adult population of patients at the UNMC College of Dentistry student clinics, and 2) explore potential risk factors that may lead to NCCLs.
Methods: A convenience sample of 46 adult subjects ranging from 21 to 80 years old with a minimum of 20 natural teeth without gingival restorations were selected. Each subject received a digital intraoral scan that was reviewed by 3 examiners for presence of NCCLs. Subjects also completed an electronic survey gathering information related to their diet; exercise; health; lifestyle; and dental procedures, practices, and habits.
Results: Among our findings, 48% of subjects had at least one facial NCCL. Overall, the average percentage of teeth with NCCLs was 8%. Subjects who reported any of the following: tooth clenching, tooth grinding, fingernail biting, and hard object biting habits had significantly lower percentages of teeth with NCCLs (p<0.05). There was a significant positive correlation between age and percent of NCCLs. There was a significant negative correlation between percent NCCLs and frequency of consumption of fruit juice and/or energy drinks (those with increased consumption had fewer NCCLs).
Conclusions: Many of our findings were surprising and some counterintuitive. Much is yet to be learned about the prevalence and etiology of NCCLs.
