Tooth Loss Observation in Patients with Periodontitis in Recall Period based on the Staging and Grading System of a World Classification 2017

Periodontitis is a disease revolving around inflammation and result in destruction of gingiva, periodontal tissue, and alveolar bone which function as anchorage of teeth. Past studies tried to use periodontal risk assessment tools to predict tooth loss. The new classification of periodontal disease, World Classification 2017, categorized periodontitis into stages and grades based on parameter such as bone loss, which also a risk factor of tooth loss. so it was considered to be potential periodontal tooth loss predictor. To investigate relationship between diagnosed periodontitis stages and grades on baseline to tooth loss on 1-3 months, 4-6 months, 7-9 months, 10-12 months, and 13-24 months recall. This study is done retrospectively using secondary data from 2018-2021 at Dental Teaching Hospital Universitas Indonesia. One hundred sixty six samples collected for the study. Data is analyzed by comparative test using IBM SPSS Statistics 26 Program. There is significant difference of tooth loss by periodontitis stage IV between 1-3 months to 13-24 months recalls from baseline, grade A between 1-3 months to 13-24 months, grade C between 13-24 months to 1-3 months, 4-6 months, and 10-12 months recalls from baseline. Conclusions: Tooth loss due to periodontitis is differ based on stages and grades between recalls.
