Clinical characteristics and related factors of non-carious cervical lesions in patients examined at School of Dentistry, Viet Nam

Tóm tắt

Objective: To describe the clinical characteristics and analyze the factors related to non-carious cervical lesions (NCCLs) at School of Dentistry, Vietnam. Methods: A cross-sectional descriptive study was conducted on 59 patients with 367 teeth affected by non-carious cervical lesions. Clinical characteristics and related habits were collected and analyzed using Chi-square or Fisher’s exact tests. Results: NCCLs were predominantly observed as V-shaped lesions with smooth and glossy surfaces, located at the cervical region near the gingival margin, and most commonly affecting premolars. Among affected teeth, premolars showed the greatest mean width and depth (1.76 ± 0.74 mm and 1.34 ± 0.52 mm, respectively), while molars exhibited the greatest lesion length (5.36 ± 0.82 mm). The condition was more prevalent in individuals aged ≥40 years (79.7%) and frequently associated with dentin hypersensitivity (86.4%) and gingivitis. Horizontal brushing technique was significantly more common in males and older adults (p < 0.01), and the use of hard-bristled toothbrushes was notably higher in males (p < 0.001). Bruxism was reported in 22.0% of patients, with slightly higher rates in females and younger individuals, though differences were not statistically significant (p > 0.05). Acidic dietary habits were more common in females (p < 0.05) and those under 40, but age differences were not significant (p > 0.05). These findings support the multifactorial etiology of NCCLs and underscore the importance of early identification and individualized prevention strategies.
