A localized stage 3 periodontitis was classified as a moderate SPT diagnosis, and a generalized stage 3 or stage 4 periodontitis and a molar‐incisor pattern with CAL‐V ≥ 5 mm were categorized as a severe baseline diagnosis. These authors assessed BOP in a different way from the present study: “An individual BOP‐index basing on the %s of the dichotomous scores was calculated. In multi‐rooted teeth, only the root with the apparently largest bone loss was measured (S.A.). Cohen's weighted kappa, as a measure of agreement between categorical scores, is subject to the classification used. Patients were diagnosed according to the 1999 classification of periodontal diseases valid at the time of the respective re‐examination (SPT) (Armitage, 1999). Percentage of residual pockets and BOP were assessed for six sites per tooth (mesiobuccal, buccal, distobuccal, distooral, oral, mesiooral) (PRA6) (standard measurements at the Dept. Influence of interleukin-1 gene polymorphism on the outcome of supportive periodontal therapy explored by a multi-factorial periodontal risk assessment model (PRA). Using periodontal charts documented at the respective SPT visit analysed for this study, all patients were assigned to stages according to the 2018 classification based on inter‐proximal CAL‐V, teeth missing due to periodontal reasons and complexity (Tonetti et al., 2018). A type 1 error below 5% was accepted for statistical significance. The patient was considered as statistical unit. Recording more sites will inevitably result in the same but, more likely, in higher frequencies and particularly higher absolute counts. 2: Tooth‐related factors, Die Parodontalbetreuung. As certain levels of BOP are associated with certain risk categories we would expect respective thresholds regarding, for example a plaque index. In contrast, calculation of the PRA is based on only six factors. Crossref. A total of 185 teeth (49%) showed no FI (Hamp, Nyman, & Lindhe, 1975). Following publication of that article, Page and Martin20 introduced the Oral Health Information Suite (OHIS), which provides a disease score on scale of 1 (health) to 100 (seve… In four patients (8%), the PRA6 was one risk category lower than PRCred (Figure 3a). In addition, there are other risk assessment tools that are not discussed here (Chandra, 2007; Dhulipalla et al., 2015; Lindskog et al., 2010a, 2010b; Trombelli et al., 2017). BMC Oral Health.

Unfortunately, PRC does not explain which criteria may be used to decide whether “oral hygiene (is) in need for improvement,” “previous recall intervals (were) irregular,” or “scaling and root planing (are) complete” or not. Descriptive data were presented with respect to the scale level and distribution of the data. In clinical routine, BOP is scored after PPD assessment (Eickholz et al., 2008). Furthermore, the authors did not specify at how many sites per tooth PPD and BOP were recorded. However, the evaluated methods for the calculation of the patient´s individual risk may provide inconsistent allocation to different risk categories.

Finally, a classification of low, moderate or high risk was assigned. Crossref.

Thus, many publications assess risk factors for tooth loss as result of progressing attachment loss (Baumer et al., 2011; Dannewitz et al., 2016; Eickholz, Kaltschmitt, Berbig, Reitmeir, & Pretzl, 2008; Graetz, Plaumann, et al., 2017; Graetz, Salzer, et al., 2017; Kocher et al., 2005; Muller, Eickholz, Reitmeir, & Eger, 2013; Pretzl, Kaltschmitt, Kim, Reitmeir, & Eickholz, 2008; Pretzl, El Sayed, Weber, Eickholz, & Baumer, 2018). This leads to an assignment of a moderate risk category instead of the high category Periodontol 2000. To be able to relate a SPT interval to the PRC categories and to directly compare the two risk classifications, the five categories of the PRC were summarized into three categories (Sai Sujai et al., 2015): the categories “very low” and “low risk” as well as the categories “moderate” and “high risk” were each merged into one category “low” or “moderate risk” (reduced PRC = PRCred).

While several tools have been proposed, the implications of patient stratification using these tools in terms of clinical decision‐making are unclear, and their efficacy/effectiveness in terms of improvement of periodontal care and clinical outcomes has not been evaluated. Maria Emanuel Ryan, Ying Gu, Host Modulation, Carranza's Clinical Periodontology, 10.1016/B978-1-4377-0416-7.00048-2, (492-501), (2012). Over the past 10 years, the American Academy of Periodontology (AAP) has offered guidelines that incorporate risk assessment in patient management, noting that without risk assessment, comprehensive dental and periodontal evaluations are incomplete. A recommendation for or against one of the two systems cannot be made, even if the classification of the degrees of progression in the currently valid classification for periodontal diseases is much closer to PRA than to PRC (Tonetti et al., 2018). In addition, it must be considered that, besides the division of kappa scores chosen here, there are other categorization options (Cicchetti & Sparrow, 1981; Fleiss, 1981; Landis & Koch, 1977; Viera & Garrett, 2005) that may allow for other interpretations. For example, if the patient is a smoker, the smoking cessation protocol should be included in the tr… The online periodontal chart cannot be saved on the hard drive similar to a text document.

The statistical analysis was carried out using a statistics program (IBM® SPSS® Statistics version 22 software package: IBM Corp., Armonk, NY, USA). It consists of an assessment of the level of infection (full mouth bleeding scores), the prevalence of residual periodontal pockets, tooth loss, an estimation of the loss of periodontal support in relation to the patient's This probability of something happening (e.g., suffering from disease/‐progression) is known as risk.
