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

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.
