- Aim The objective of this study was to evaluate consistency and accuracy of the periodontitis staging and grading classification system. Methods Thirty participants (10 periodontal experts, 10 general dentists and 10 undergraduate students) and a gold-standard examiner were asked to classify 25 fully documented periodontitis cases twice. Fleiss kappa was used to estimate consistency across examiners. Intraclass correlation coefficient (ICC) was used to calculate consistency across time. Quadratic weighted kappa and percentage of complete agreement versus gold standard were computed to assess accuracy. Results Fleiss kappa for stage, extent and grade were 0.48, 0.37 and 0.45 respectively. The highest ICC was provided by students for stage (0.91), whereas the lowest ICC by general dentists for extent (0.79). Pairwise comparisons against gold standard showed mean value of kappa >0.81 for stage and >0.41 for grade and extent. Agreement with the gold standard for all three components of the case definition was achieved in 47.2% of cases. The study identified specific factors associated with lower consistency and accuracy. Conclusions Diagnosis was highly consistent across time and moderately between examiners. Accuracy was almost perfect for stage and moderate for grade and extent. Additional efforts are required to improve training of general dentists.

- AIMS: The aim of this study was to explore general dental practitioners' (GDP) attitude to periodontal furcation involvement (FI).MATERIALS AND METHODS: An online survey focused on diagnosis and management of periodontal FI was circulated to general dental practitioners in 7 different countries.RESULTS: A total of 400 responses were collected. Nearly a fifth of participants reported rarely or never taking 6-point pocket charts. 65.8% of participants had access to a Nabers probe in their practice. When shown clinical pictures and radiographs of FI-involved molars, the majority of participants correctly diagnosed it. Although 47.1% of participants were very/extremely confident in detecting FI, only 8.9% felt very-extremely confident at treating it. Differences in responses were detected according to country and year of qualification, with a trend towards less interest in periodontal diagnosis and treatment in younger generations. Lack of knowledge of management/referral pathways (reported by 22.8%) and lack of correct equipment were considered the biggest barriers to FI management. Most participants (80.9%) were interested in learning more about FI, ideally face-to-face, followed by online tutorials.CONCLUSIONS: Plans should be put in place to improve general dentists' knowledge and ability to manage FI, as this can have a significant public health impact.
