Abstract

Objective: This study aims to determine the prevalence of Kennedy Classification in partially dentate individuals and investigate its correlation with key sociodemographic characteristics, including age, gender, educational attainment, income, smoking habits, and diabetes status.

Study Design: This was a cross-sectional study.

Place and Duration of Study: The study was conducted in the Department of Prosthodontics, Abbottabad International Medical Institute, from April to September 2022.

Materials and Methods: A total of 400 partially dentate patients were included. Data on demographics and oral classification (Kennedy Classes I–IV) were collected. Statistical tests, including chi-square and multinomial logistic regression, were applied to determine associations.

Results: The most prevalent classification was Class I (35.0%), followed by Class III (27.5%), Class II (25.0%), and Class IV (12.5%).

Multinomial logistic regression revealed that:

Current smokers had significantly higher odds of presenting with Class IV edentulism (OR: 2.5, 95% CI: 1.5–4.1, p < 0.01).
Individuals aged 80 and above had higher odds of Class II (OR: 2.8, p < 0.01) and Class III (OR: 2.2, p < 0.01) compared to younger adults.
Diabetic individuals were more likely to exhibit Class IV edentulism (OR: 2.1, p < 0.01).

Conclusion: Sociodemographic factors, notably age, smoking, and diabetes, significantly influence the distribution of Kennedy Classification among partially dentate adults. These findings underscore the need for targeted prevention and prosthetic
