- Biologiska markörer som baserar sig på egenskaper och aktivitet hos bakterier i dentala biofilmer skulle kunna användas för att identifiera patienter med hög risk för karies och parodontit. Genom att studera hur tandläkare gör riskbedömningar och tar beslut om åtgärder kan man få ett bra underlag för att förbättra praxis.

- BACKGROUND: Multivariable prediction models are used in oral health care to identify individuals with an increased likelihood of caries increment. The outcomes of the models should help to manage individualized interventions and to determine the periodicity of service. The objective was to review and critically appraise studies of multivariable prediction models of caries increment.METHODS: Longitudinal studies that developed or validated prediction models of caries and expressed caries increment as a function of at least three predictors were included. PubMed, Cochrane Library, and Web of Science supplemented with reference lists of included studies were searched. Two reviewers independently extracted data using CHARMS (Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies) and assessed risk of bias and concern regarding applicability using PROBAST (Prediction model Risk Of Bias ASessment Tool). Predictors were analysed and model performance was recalculated as estimated positive (LR +) and negative likelihood ratios (LR -) based on sensitivity and specificity presented in the studies included.RESULTS: Among the 765 reports identified, 21 studies providing 66 prediction models fulfilled the inclusion criteria. Over 150 candidate predictors were considered, and 31 predictors remained in studies of final developmental models: caries experience, mutans streptococci in saliva, fluoride supplements, and visible dental plaque being the most common predictors. Predictive performances varied, providing LR + and LR - ranges of 0.78-10.3 and 0.0-1.1, respectively. Only four models of coronal caries and one root caries model scored LR + values of at least 5. All studies were assessed as having high risk of bias, generally due to insufficient number of outcomes in relation to candidate predictors and considerable uncertainty regarding predictor thresholds and measurements. Concern regarding applicability was low overall.CONCLUSIONS: The review calls attention to several methodological deficiencies and the significant heterogeneity observed across the studies ruled out meta-analyses. Flawed or distorted study estimates lead to uncertainty about the prediction, which limits the models' usefulness in clinical decision-making. The modest performance of most models implies that alternative predictors should be considered, such as bacteria with acid tolerant properties.TRIAL REGISTRATION: PROSPERO CRD#152,467 April 28, 2020.

Caries risk assessment : a comparison between the computer program 'Cariogram', dental hygienists and dentists

- The 'Cariogram', which is an interactive PC-program for caries risk evaluation, illustrates the interaction between caries related factors and expresses the caries risk graphically. It also demonstrates a weighted impact of the different etiological factors on the risk. The aim of this paper was to use the Cariogram program on a set of patients, and to compare the outcome of its risk evaluation with those made by dental hygienists and dentists. A questionnaire, containing the descriptions of five patients with detailed information on nine factors generally associated with caries, was given to the participants. They were asked to rank the patients according to their 'chance to avoid dental caries' during the coming year. The results were compared with the assessments obtained from the Cariogram. Results: 73.5% of the dental hygienists and 78.5% of the dentists ranked the patients for caries risk either identically or with only one deviation when compared to the Cariogram. It was concluded that the 'opinion' of the Cariogram on caries risk was in agreement with that of the majority of the participants. In addition, the Cariogram program induced discussions about the relative impact of etiological factors of caries. It is envisaged that the Cariogram can serve as one further tool in the teaching of caries risk.

- This paper reviews some common methods for the assessment of caries risk. It also describes a new way of illustrating the caries risk profile of an individual, the Cariogram. Past caries experience and socioeconomic factors are often used for prediction of caries. As prediction models, the methods are simple, inexpensive and fast. However, they are not risk models, as they do not specify which particular risk factors are operating. Various biological factors can be used for risk assessment. Common ones are bacteria, diet and host factors. Taken separately, these biological factors often have limited predictive values. Socioeconomic factors often have a heavy impact on the biological factors as they can explain why an individual, for example, has a cariogenic diet or neglects oral hygiene. The biological factors are the immediate cause of the cavities. Caries experience is an illustration of how the host copes up with the biological activity. To facilitate the interpretation of biological data, the Cariogram was developed. It is a computer program showing a graphical picture that illustrates a possible overall caries risk scenario. The program contains an algorithm that presents a 'weighted' analysis of the input data, mainly biological factors. It expresses as to what extent different etiological factors of caries affect caries risk. The Cariogram identifies the caries risk factors for the individual and provides examples of preventive and treatment strategies to the clinician.

- This study evaluated whether variations in education level and experience among dental staff influence the diagnostic accuracy of carious lesions on digital radiographs. Three student groups and a fourth group of general practitioners (Dentists) with more than five years of clinical experience participated in this study.The student groups were (i) dental students in their final (tenth) semester (DS-10), (ii) dental students in the sixth semester (DS-6) who just finished dental radiology training, and (iii) dental hygiene students (DHS) in their final (fourth) semester. Seven observers from each group participated. Standard radiographs of 100 extracted teeth (premolars and molars) were taken. The 28 observers evaluated the images for approximal carious lesions on a standard monitor. All evaluations were made in ambient light below 50 lux. Receiver operating characteristic curves were plotted to assess results. The standard criterion for healthy or carious lesions was a histological examination of sliced teeth. Kappa statistics evaluated intra-observer agreement. For carious lesions that had extended into the dentine, significant differences were found between (i) Dentists and all other groups, (ii) Dentists and DS-10 (p < 0.01), and (iii) Dentists and DS-6 and DHS (p < 0.001). Differences between DS-10 and DHS (p < or = 0.05) were also significant. In this study, education level and experience clearly influenced the diagnostic accuracy of approximal carious lesions that had extended into the dentine on digital radiographs.

- An interactive educational PC-program for caries risk evaluation, the ‘Cariogram’, was developed. It illustrates the interaction between caries related factors and expresses the caries risk graphically. It also expresses a weighted impact of different aetiological factors on the risk. The aim of this paper was to use the Cariogram program on a set of patients, and to compare the outcome of its risk evaluation with those made by dental students and faculty teachers. A questionnaire was given to the participants, containing descriptions of 5 patients with detailed information on 9 factors generally associated with caries. The participants were asked to rank the patients according to their ‘chance to avoid dental caries’ during the coming year. The results were compared with the assessments obtained from the Cariogram and the similarity calculated by group average cluster analysis. Results: 86% of the respondents ranked the patients for caries risk either identical or with only 1 deviation compared to the program. No difference was seen between students and teachers. The cluster analysis identified 5 distinct patterns of ranking the patients with a maximum distance of 0.6 compared to the program. It was concluded that the ‘opinion’ on caries risk of the Cariogram was in agreement with that of the majority of the responders. In addition, the use of the program induced discussions about the relative impact of caries aetiological factors, and it is believed that the Cariogram can serve as one further option in the teaching of caries risk.
