A Novel System for Predicting Periodontal Outcomes: Analysis of the 2017 Periodontitis Classification based on a Systematic Review
Abstract:
This study assesses the 2017 Classification of Periodontitis from a prognostic perspective, extending beyond mere tooth loss. Through a systematic review, we compare this classification to previous major systems, examining their prognostic capabilities. Additionally, we introduce a new, simpler, and more efficient prognostic system. A total of 89 articles were selected from database searches, and a color gradient scale was utilized to compare the 2017 classification with earlier prognostic systems. The prognostic capability of the 2017 classification is comparable to McGuire’s system, with various stages and grades aligning with different prognostic outcomes. We propose a novel periodontal prognostic scale (PPS) system based on 12 parameters. In conclusion, the 2017 classification offers both diagnostic and limited prognostic capacities for assessing periodontitis. Visual comparisons with major prognostic systems indicate its potential for estimating periodontal prognosis, with the best match found in Kwok and Caton’s system. The introduction of the new PPS system emphasizes convenience and simplicity, with plans for verification and updates in future studies.
