Aim: Among various dental ailments, periodontitis has always had a towering popularity. The inauguration of new classification scheme for periodontal diseases and conditions in 2017 World Workshop has a remarkable impact on the diagnosis of periodontal diseases worldwide. This study is based on comparison between the two classifications by American Academy of Periodontology for diagnosing periodontitis. Materials and Methods: This study focuses on the prevalence estimates of periodontitis by diagnosing the periodontal diseases using two different criteria simultaneously: the first criterion was based on the classification approved in 1999 World Workshop and the other criterion was based on the new classification scheme of periodontal diseases and conditions in 2017 World Workshop. Results: It was found that there was significant reduction in the prevalence estimates (P < 0.001) of periodontitis following the new classification scheme. Conclusion: The new classification scheme recognizes the clinical salience of periodontitis and is more likely to influence the treatment modality of long sufferings of the patients having periodontal problems across the globe. The new classification will also lay the base for future research in the field of dentistry. More future studies are required to assess the prevalence of periodontitis following new classification scheme on a larger scale.
