Background and Objective: Being aware of the prevalence and risk factors associated with non-carious cervical lesions (NCCLs) is of great importance for their prevention and clinical management. Accordingly, this study was conducted to examine the frequency of NCCLs and the risk factors associated with them among students of Babol Dental School.
Methods: This observational-analytical study was conducted on 210 students of Babol Dental School. A questionnaire containing demographic information and questions related to hygiene and dietary habits was provided to the participants. Then, each student was examined, and the teeth were scored based on the Smith and Knight index. The frequency of NCCLs was investigated according to sex, location and characteristics of the lesion, and its association with the involved jaw, toothbrushing method, diet, and gastroesophageal reflux.
Findings: Of the 210 students, 47 (22.4%) had NCCL lesions. The frequency of lesions did not show a significant relationship with sex, involved jaw, type and method of toothbrushing, frequency of consuming fruit, pickles, and soft drinks, smoking, gastroesophageal reflux, or dry mouth; however, the frequency of lesions demonstrated a statistically significant difference in terms of anterior or posterior position and buccal or lingual location (p<0.001 and p=0.001, respectively), and most lesions were anterior (61.7%) and buccal (57.4%). Furthermore, the frequency of lesions had a significant relationship with bulimia nervosa (p=0.03).
Conclusion: According to the results of the present study, no relationship was found between hygiene and dietary habits and the presence of NCCLs. However, a significant relationship was observed between bulimia nervosa and NCCLs. |
