Abstract

Objective: To evaluate gender-based variations in the width, length, and width–length (W/L) ratio of maxillary central incisors (MCIs) among adult patients.

Study Design: Cross-sectional study

Place and Duration of Study: Department of Prosthodontics, Islamabad Medical & Dental College, Islamabad, Pakistan; from January 2023 to July 2023.

Materials and Methods: A total of 150 participants (75 males, 75 females) were recruited through purposive sampling. Width and length of right and left MCIs were measured with digital calipers, and W/L ratios were calculated. Data were analyzed in SPSS v26 using descriptive statistics and independent samples t-tests, with significance set at p < 0.05.

Results: Participants were mostly 26–45 years old, with oval arch form (40%), Class I occlusion (60%), and intact MCIs (93.3%). Males exhibited significantly larger MCIs than females on both sides. For the right incisor, males showed greater mean width (8.95 ± 0.42 mm) and length (10.10 ± 0.51 mm) than females (8.60 ± 0.38 mm; 9.72 ± 0.48 mm), p < 0.001. The left incisor showed similar differences (males: 8.92 ± 0.40 mm width, 10.08 ± 0.49 mm length; females: 8.58 ± 0.36 mm, 9.70 ± 0.46 mm; p < 0.001). No significant gender difference was observed in W/L ratios (p = 0.437 right, p = 0.512 left), indicating consistent proportional morphology.

Conclusion: While males have larger maxillary central incisors than females, the W/L ratio is comparable between genders. These findings have implications for dental aesthetics, prosthodontic rehabilitation, and forensic identification.
