Abstract

Objective: This study aims to assess the prevalence of mandibular third molar impaction among individuals with different vertical skeletal facial types and to investigate relationships with demographic factors such as age and sex.

Study Design: Cross-sectional study

Place and Duration of the Study: Orthodontics Department of Rehman College of Dentistry, Peshawar, Pakistan, from January 2023 to June 2024.

Materials and Methods: A cross-sectional study was conducted on a sample of 100 individuals categorized into norm divergent (40%), hypo divergent (30%), and hyper divergent (30%) skeletal facial types. The occurrence and classification of mandibular third molar impaction were documented. Logistic regression analysis was used to examine the association between facial type and impaction.

Results: Impaction occurred in 70% of the sample, with mesioangular impaction being the most common (50%). Individuals with a hyper divergent skeletal facial type showed a significantly higher likelihood of impaction (OR = 2.50, 95% CI: 1.00–6.25, p = 0.048). Age exhibited a trend towards significance (p = 0.065), indicating higher susceptibility among younger individuals, while sex was not significantly associated with impaction.

Conclusion: The findings suggest that individuals with a hyperdivergent skeletal profile are at an increased risk of mandibular third molar impaction. This highlights the importance of considering skeletal morphology in the assessment and management of early third molars. Further studies with larger sample sizes are recommended to validate these findings.
