Staging and grading without data: rethinking periodontal classification in low-resource settings — a critical mini-review
Year: 2026
Type: review
Abstract: The 2017 World Workshop introduced a staging and grading framework intended to improve diagnostic consistency and support individualized periodontal care. Although conceptually robust, its practical application depends on clinical, radiographic, and systemic data that are not consistently available in many healthcare environments. Reports from both high‑income and resource‑limited settings indicate that implementation challenges may arise even when adequate infrastructure exists. To critically examine the feasibility of applying the grading component of the 2017 periodontal classification in settings with limited diagnostic resources and to contextualize broader implementation challenges described in the literature. A narrative review of publications from 2017 to 2026 was conducted using PubMed, Scopus, and Web of Science. Professional society documents and selected grey literature were also consulted. Sources addressing data availability, radiographic limitations, inter‑examiner variability, educational barriers, and equity‑related aspects of periodontal diagnosis were included. Evidence shows that grading may be difficult to apply consistently when longitudinal radiographs, historical documentation, or systemic biomarkers—such as HbA1c in patients with diabetes—are unavailable, although indirect indicators of progression remain permissible. Studies from various regions report diagnostic uncertainty associated with incomplete examination protocols, radiographic overlap, difficulty assessing furcation involvement, and limited calibration. These factors may contribute to misclassification, with potential implications for treatment decisions and epidemiologic estimates. Literature also highlights the disproportionate burden of periodontal disease among disadvantaged populations and its associations with systemic conditions. Feasibility constraints reflect a broader mismatch between complex diagnostic requirements and real‑world system capacity. Context‑appropriate simplified grading approaches based on accessible clinical and behavioral indicators may offer pragmatic support in constrained environments, but require further evaluation before routine adoption.
