Prevalence and severity of periodontitis among adults in Côte d'Ivoire according to the new EFP/AAP periodontal disease classification.

Abstract

Background: To describe the prevalence and severity of periodontitis in patients attending the Periodontics Service of the Cocody University Hospital at Abidjan.

Methods: This retrospective observational study reviewed records of patients aged 20-80 years who attended the Periodontics Service between January 2014 and December 2018. Periodontitis was diagnosed, according to the 2018 EFP/AAP new classification of Periodontal and Peri-Implant Diseases and Conditions. Chi-square test, 1-factor Anova test, and logistic regression were performed for analysis.

Results: A total number of 596 patients were included. The mean age was 44.94 ± 14.34 years and 59.20% of were males. 2 (0.40%) patients were classified as Stage I, 221 (37.08%) as Stage II, and 373 (62.58%) as Stage III/V; the extent of periodontitis was generalized in 39.77% of patients. PD ≥ 6 mm, missing teeth ≥ 5 and mobile teeth were present in 47.15%, 26.35% and 25.50% of the sample, respectively.Severity of periodontitis were associated with age (p < 0.001), socio-economic status (p=0.001), diabetes (p < 0.001), missing teeth (p < 0.001) and smoking (p=0.009). Age (OR= 1.59, 95% CI: 1.11-2.26) and missing teeth (OR= 2.31, 95% CI: 1.08-4.89) were identified as independent risks indicators.

Conclusion: The prevalence and severity of periodontitis were high. Risks indicators identified may allow early detection and management of groups at high risk in Côte d'Ivoire.
