Investigating Altered Passive Eruption: Prevalence and Correlation with Crown Dimensions of Maxillary Anterior Teeth in Punjab

Altered Passive Eruption and Crown Dimensions in Maxillary Anterior Teeth

Abstract

Objective: This study aims to explore the prevalence of Altered Passive Eruption (APE) and its relationship with the width, length, and width-to-length (W/L) ratios of maxillary anterior teeth in the Punjab population. Study Design: Cross-sectional study. Settings: Institute of Dentistry, CMH Lahore Medical College, Lahore Pakistan. Duration: June 1, 2023 to December 30, 2023. Methods: This study after the approval of the Institutional Review Board of the Institute of Dentistry, CMH Medical College, on a sample of 128 participants using a consecutive sampling technique. Inclusion criteria required participants to be over 20 years old, non-smokers, and have intact maxillary front teeth. Exclusion criteria included recent orthodontic treatment, systemic conditions, and medications affecting gingival health. Clinical assessments were performed to measure tooth dimensions, and data was analyzed using SPSS v24. Results: The study found a 30.47% prevalence of APE in the sample population. Significant gender differences were observed, with males exhibiting larger maxillary anterior teeth dimensions than females. However, age and height did not show significant associations with tooth dimensions. The W/L ratio of central incisors and other dimensional differences between genders were statistically significant (p < 0.001). Conclusion: The prevalence of APE is notably high, emphasizing the need for awareness among clinicians. Gender-specific differences in tooth dimensions should be considered in dental assessments and treatments. Future research should explore the genetic and environmental factors influencing APE and employ advanced measurement techniques to enhance diagnostic and treatment strategies.
