On the lingual side, the mean for all teeth (central, lateral, and canine) was 1.7 mm. The study demonstrated a significant difference in distance across age groups (< 30 and ≥ 30 years) for all teeth on both the buccal and lingual sides, except for the canine on the buccal side.Conclusion: The distance from the CEJ to the bone crest on both the buccal and lingual sides varies significantly by age group. This data is essential for developing orthodontic, implant, and periodontal therapies.Keywords: alveolar bone crest, canines, cementoenamel junction, central incisors, cone-beam computed tomography, lateral incisors
