    Objective: This descriptive cross-sectional study aimed to characterize the morphological and periodontal features of altered passive eruption maxillary anterior teeth to better target the treatment method for individual patients. Methods: 38 patients (27 females and 11 males) with altered passive eruption (APE) type 1 were included. Teeth and periodontal parameters were measured on study casts and cone-beam computed tomographic images. Results: The width/length ratios of the central incisors, lateral incisors, and canines were 1.06, 1.02, and 1.03 mm, respectively. The mean distance between the cement–enamel junction and the alveolar bone crest was <1.5 mm. Thick gingival tissue was observed in 68.4% of the sample, and the buccal alveolar bone thickness was >1 mm. P values of less than 0.05 were considered statistically significant. Conclusion: No association between ging.. Read More»
