OBJECTIVES: To quantitatively evaluate the progression of non-carious cervical lesions (NCCLs), gingival recession (GR), and occlusal tooth wear (OTW) over 25 years.
METHODS: This observational, retrospective study involved 33 dental students who completed a questionnaire regarding their oral habits, diet, and health information. Impressions from the baseline and the 25-year follow-up were used to create digital casts, which were analyzed with 3D software (Geomagic Control; 3D Systems) to measure the progression of NCCLs, GR, and OTW. Occlusal analysis from Phase I, using the T-Scan system (Tekscan), was also included to evaluate occlusal interferences.
RESULTS: NCCL dimensions (area, height, and width) showed moderate associations with GR and only weak correlations with OTW. Multivariate regression analyses identified significant factors associated with NCCL progression. For NCCLs, visible plaque, vigorous toothbrushing, occlusal interferences, dentin hypersensitivity, alcohol consumption, smoking, and frequent exposure to acidic or cariogenic diets were associated with increased NCCL progression. For GR, was significantly associated with occlusal contact, dentin hypersensitivity, alcohol consumption, and smoking. For OTW, unilateral mastication, long-term orthodontic treatment, and smoking were positively correlated with wear progression.
CONCLUSIONS: Mechanical and behavioral factors-particularly vigorous toothbrushing, occlusal interferences, and lifestyle habits such as smoking and alcohol consumption-significantly influenced the long-term progression of NCCLs, GR, and OTW. Mandibular molars and premolars were the most frequently affected teeth.
CLINICAL SIGNIFICANCE: The use of digital three-dimensional analysis allows accurate monitoring of NCCLs, GR, and OTW. Preventive measures should prioritize controllable risk factors, including brushing habits, smoking, alcohol consumption, and occlusal imbalances.
