“…This could make treatment outcomes more predictable and improve our ability to share findings with our patients. A few examples of cases that demonstrate the practical implementation of the BPS‐I were published recently 34,35 . More importantly, the results presented in this manuscript demonstrated that the BSP's pragmatic approach through implementing a reductionist model of the original 2017 WWC neither affected the class allocation nor the prognostic performance of the system.…”

Background:The British Society of Periodontology (BSP) implemented a simplified version of the 2017 World Workshop Classification (WWC) on staging and grading of periodontitis, for use in UK clinical practice. The aim of this study was to assess the long-term (>10 years) prognostic capability of BSP's implementation (BSP-i) compared with the 2017 WWC, using periodontal-related tooth loss (TLP) as a disease outcome. Methods: Data on medical history, smoking status, and clinical periodontal parameters were retrieved from 270 patients who received non-surgical and surgical periodontal therapy from 1966 to 2007. Each patient received a baseline diagnosis according to the 2017 WWC and the BSP-i guidelines for implementation. Univariate multilevel Cox regression frailty models were performed to analyze the association between variables with TLP. A post-hoc comparison with Bonferroni correction was performed to analyze interclass comparisons. The prognostic performance of both systems was analyzed using Harrell C index. Results:The prognostic performance of both systems was very similar (0.922 for the 2017 WWC and 0.925 for the BSP-i). The singular prognostic performance of BSP stage was slightly higher than that of 2017 WWC stage (0.9212 versus 0.9188), while the 2017 WWC grade showed a slightly better performance than BSP grade (0.9175 versus 0.9155). BSP-i's extent performed better than the 2017 WWC extent (0.9203 versus 0.9098); however, in the 2017 WWC extent, the class "localized" was associated with a better prognosis than "generalized." Conclusion:The overall prognostic performance of the two systems was excellent, with both systems having a Harrell C index score of >0.92.

With patients living longer and retaining their natural teeth for longer, dental healthcare professionals are presented with new challenges. This paper outlines considerations for dental health care professionals managing periodontal disease in an ageing population. Although age itself is not considered an independent risk factor for periodontal disease, there may be complicating factors associated with ageing that impact upon the planning and delivery of care. This paper describes current evidence for the management of periodontal disease in the context of health conditions associated with ageing. It identifies aspects to consider and provides advice on how treatment planning for this patient population may be tailored.

“…In 2018, the AAP and the European Federation of Periodontology (EFP) proposed a new classification of periodontal and peri‐implant diseases and conditions 29,30 . With an explicit case definition and sub‐classifying standards for periodontitis, the renewed system is not merely instructive for daily clinical practice, 31–38 rather also suggested for epidemiological surveys.…”

Background Based on the 2018 classification, we aimed to determine the prevalence, distribution, and progression of periodontitis in the rural Chinese population without access to dental care. Methods In all, 404 subjects (28.7 ± 8.9 years, M:F = 182:222) were randomly enrolled in 1992 and re‐called in 1996. With the new classification, the prevalence and distribution of stage, grade, and extent were characterized. Stage progression was compared with the progression of clinical attachment loss (CAL) and radiographic bone loss (RBL). Results At baseline, 94.1% villagers suffered from periodontitis, of whom 53.7% were in Stage III/IV. The prevalence of Stage III/IV increased from 18.2% in the age group of 15 to 24 years to 60.9% in 25 to 34‐year‐old group and 88.7% in the 35 to 44‐year‐old group. Significantly more Stage III/IV, generalized, and Grade C periodontitis were found in male villagers than female villagers. In 1996, the prevalence rate of periodontitis increased to 98.5%, with 80.0% in Stage III/IV. Further, 84.2% villagers presented with Grade C periodontitis based on longitudinal ΔCAL. The rate of progression (≥1 site with ΔCAL ≥3 mm) was 63.7%. Stage progression correlated significantly with CAL and RBL progression in Stage I/II, but this association was not found in Stage III/IV. Among subjects with disease progression in Stage III/IV, 90.4% shifted from localized to generalized cases. Furthermore, ceiling effects were observed in Stage III/IV. Conclusions In villagers without access to dental care, 94.1% suffered from periodontitis, with more than half having Stage III/IV disease based on the 2018 classification. The majority cases presented with rapid periodontal progression. Although stage progression correlated significantly with CAL and RBL progression in Stage I/II, ceiling effects existed in Stage III/IV.
