Objective: To determine the mucogingival parameters of the maxillary anterior teeth in Peruvian dental students, including the width of keratinized gingiva, gingival phenotype, interdental papilla height, and gingival zenith position. Materials and Methods: A cross-sectional study was conducted among 128 randomly selected dental students from a private university in Lima, Peru. Prior to data collection, a pilot study and examiner calibration were performed. Mucogingival parameters were clinically assessed using a North Carolina periodontal probe. Measurements were analyzed by tooth type, sex, and age using the Chi-square test, Mann–Whitney U test, Friedman test, and Dunn’s post hoc test (α = 0.05). Results: The mean width of keratinized gingiva ranged from 4.99 mm to 5.29 mm, and the height of the interdental papilla ranged from 3.99 mm to 4.41 mm. A thick gingival phenotype was obs...
