# Clinical Incorporation of the 2017 Classification of Periodontal Diseased Conditions: Part I (Diagnosis of Periodontitis Involving Data From 4,993 Patients)

## TL;DR

This study evaluates how well the 2017 periodontal disease classification system works in real-world dental practice using data from nearly 5,000 patients.

## Contribution

The study demonstrates the practical application of the 2017 classification system in routine dental care.

## Key findings

- Most patients with gingivitis showed bleeding on probing and calculus buildup.
- Stage II grade B periodontitis patients showed varying levels of disease progression.
- The new classification system was well-received and useful for assessing disease severity and progression.

## Abstract

Background

The new classification system for periodontal and peri-implant diseases mentioned a few key points, including (1) “clinical gingival health," which was defined for the first time, and (2) staging and grading system. Thus, the present study defines the practicability of using the current classification system in day-to-day practice.

Aim

The primary aim of this study is to determine the effectiveness of the new classification system for periodontal and peri-implant diseases and its application in routine dental practices.

Materials and methods

This is a cross-sectional retrospective, non-interventional study consisting of 4,993 patients who were under active periodontal therapy as well as supportive periodontal therapy.

Results

Among patients diagnosed with dental biofilm-induced gingivitis with no underlying risk factors, 1105 (73.3%) exhibited bleeding on probing and 897 (45%) showed supragingival or subgingival calculus. Among the stage II grade B periodontitis group, 488 (28.9%) showed beginning destructive periodontal disease and 197 (50.4%) showed established destructive periodontal disease.

Conclusion

The implementation of the new classification system in routine dental practice has been readily accepted by clinicians. Staging and grading system of classification helps in assessing the severity, extent, and progression of disease.
