Background: This study explores the intricate relationship between gingival parameters of mandibular incisors and craniofacial morphology. The research seeks to shed light on how craniofacial characteristics influence smile aesthetics and the positioning of mandibular incisors, providing valuable insights for orthodontic and periodontal treatment planning.
Methods: A total of 130 participants were meticulously selected from Bacha Khan College of Dentistry, spanning an age range of 18 to 40 years. Gingival parameters, including gingival display (mean ± SD: 3.5 ± 1.2 mm) and incisal edge position (mean ± SD: 4.7 ± 1.1 mm), were assessed using a periodontal probe, while craniofacial morphology was evaluated using cephalometric measurements. Statistical analysis, including correlation tests, was employed to examine the relationships between these parameters.
Results: The study revealed a significant negative correlation (p < 0.05) between gingival display and mandibular position (SNB), indicating that individuals with a more prominent mandibular position tend to display less gum tissue during smiling. Moreover, a strong positive correlation (p < 0.001) was found between incisal edge position and both maxillary position (SNA) and mandibular position (SNB), suggesting that craniofacial morphology significantly influences the positioning of mandibular incisors.
Conclusion: This research offers valuable insights into the relationships between gingival parameters of mandibular incisors and craniofacial morphology, with specific measurements highlighting the impact of craniofacial characteristics on smile aesthetics. These findings have important implications for orthodontic and periodontal treatment planning, contributing to the art of smile design in aesthetic dentistry.
