Comparison of 1999 and 2018 Periodontal Disease Classifications in Diabetic and Smoker Groups: A Retrospective Study

Objective: This study aims to evaluate whether the 2018 classification is more successful in reflecting severity, prevalence, and progression of disease by evaluating risk factors compared 1999. Material Methods: The 202 periodontitis patients (120 men, 82 woman; mean age: 43.23±9.81 years) demographic data, medical history periodontal clinical examinations were used assign classifications according 1999 [localized generalized aggressive/chronic (CP)] (localized Stage I-IV Grade A-C periodontitis) systems, retrospectively. Three groups established based on [diabetes mellitus (Group D), smoking S), systemic healthy H)]. Results: Statistically significant difference was detected between distributions D, S, H (p<0.001). 41.7% severe CP reclassified as Stage-3 Grade-C D group. In S group, 71.9% periodontitis. 94.7% localized mild CP, 76.9% moderate Stage-1 Grade-A periodontitis, Stage- 2 Grade-B Conclusion: provides clinicians with information about patients' current clinical-medical status prognosis (NCT04815772).
