The Prevalence of Partial Edentulism and Associated Factors: A Cross-Sectional Study

Abstract

Objective: The current study aimed to determine the prevalence of partial edentulism according to Kennedy’s classification and its association to arch, age and gender.

Methods: Data were collected from 358 patients aged 18 to 80 years. Selected patients were grouped according to gender and age (<45, =>45). Intra oral examination for each patient was done. The pattern of partial edentulism according to Kennedy’s classification was determined. Statistical analysis was done using the SPSS V26 statistical program. Chi-square test was used to test for differences in frequency at p-value<0.05.

Results and Conclusion: The rate of class III pattern in maxillary arch was significantly higher than that of mandibular arch. Class I pattern in mandibular arch was significantly higher than that of maxillary arch (25.1% vs 14%, P=0.001). No differences in frequency were found between class II and IV pattern and affected arch. Class IV was the least frequent in both dental arches. Frequency of class I and class II partial edentulism increased with age, while class III was more frequent at young age. Class IV pattern was more frequent among males than females.
