CLINICAL CHARACTERISTICS AND PREVALENCE OF SELECTED POTENTIALLY ASSOCIATED FACTORS AMONG PATIENTS WITH NON-CARIOUS CERVICAL LESIONS IN PREMOLARS AT BINH CHANH HOSPITAL
Main Article Content
Abstract
Background: Early identification of the clinical characteristics, lesion severity, and potentially associated factors of non-carious cervical lesions (NCCLs) in premolars is important for guiding prevention, treatment, and long-term follow-up. Objectives: To describe the clinical characteristics and determine the proportions of selected potentially associated factors among patients with premolar NCCLs. Materials and Methods: A descriptive cross-sectional study was conducted among 50 patients with premolar NCCLs at Binh Chanh Hospital from July 2025 to March 2026. Results: Most patients were aged ≥ 40 years (66.0%), and 54.0% were male. Stimulusinduced dentin hypersensitivity was the most common reason for seeking care (86.0%). Lesions were more frequently located in the mandibular arch (58.0%), with a similar distribution between the right and left sides, and were predominantly found on the buccal surface (96.0%). Most lesions had a depth of 1-2 mm (74.0%). Wedge-shaped lesions were the predominant morphology (64.0%), and the most common location relative to the gingival margin was at the gingival margin level (60.0%). No tooth mobility was observed. Regarding toothbrushing practices, most patients brushed once or twice daily (58.0%), used soft-bristled toothbrushes (66.0%), and reported a vertical brushing technique (54.0%). Among the potentially associated factors assessed, consumption of acidic foods or carbonated beverages (34.0%) and acid regurgitation/gastroesophageal reflux (32.0%) were the most frequently reported. Conclusion: Premolar non-carious cervical lesions were commonly observed in patients aged ≥40 years, often presenting with dentin hypersensitivity and predominantly as wedge-shaped lesions on the buccal surface with a depth of 1-2 mm. Frequently observed potentially associated factors included acidic food and carbonated beverage consumption, gastroesophageal reflux, and toothbrushing characteristics.
