    Notes: Abstract –  Objectives:  The aim of this study was to explore differences in behaviour (characteristics and opinions) among general dental practitioners (GDPs), using either a fixed (Fx) or an individualized recall interval (Iv) between successive routine oral examinations (ROEs).Methods:  In the year 2000, data were collected by means of a written questionnaire sent to a random stratified sample of 610 dentists of whom 521 responded, of which 508 (83%) were used for analysis.Results:  Two groups of GDPs were distinguished based on their answer to the question: ‘Do you apply for all patients a fixed recall interval between two successive ROEs?’ Fifty-one per cent of the GDPs (n = 257) applied Fxs for all patients, generally for a period of 6 months. Ivs were applied by 49% (n = 251) of GDPs, depending on the determination of specific patient characteristics. Logistic regression analysis showed that GDPs applying Fxs also used fixed periods between successive bitewing radiographs for all patients. Furthermore, dentists applying Ivs required more time to conduct an ROE, partly because of a more extensive periodontal screening. GDPs applying Fxs, adhered more to the opinion that a fixed recall regime (every 6 months, as existed before 1995) should be re-introduced, whereas the GDPs in support of Ivs were more in favour to support the opinion that the ROE is ‘an excellent instrument for effective, individualized oral care’.Conclusions:  Dutch GDPs differ in the way they deal with the determination of recall interval frequency. These are also specific differences in performance and opinions regarding ROE. With the changing prevalence of oral diseases and the skewed distribution within populations, further research is advocated on consistent decision making to determine the most appropriate recall policy in preventing oral disease.

    Development of clinical practice guidelines for dentists: methods for topic selection (2002)

    Notes: Abstract –Objectives: The aim of this study was to compare four methods for assessing the preferences of the dental profession for topics to be considered for the development of clinical practice guidelines.Methods:  The methods were: (1) a survey among dentists, (2) an analysis of topics discussed in dental peer groups, and (3) screening of dental journals. A fourth method was obtained from method number 3. The frequencies of the reported topics were calculated for each of the methods. For the fourth method, the number of publications per topic were plotted against the year of publication, and the slope of the linear regression line was used as an indicator. Within each of the four methods, the topics were ranked according to the frequency in which they were reported, and to the slope value. The reliability of the methods was tested by the “item-rest sum correlation”, which is the correlation of the rank positions of one method with the sum of the rank positions obtained by the remaining three methods.Results:  In using all methods, a total of 1027 topics were obtained. Reclassification resulted in 34 topics. Moderate item-rest sum correlations ranging from 0.34 to 0.48 were found for all methods, indicating that the rank order of every method moderately predicts the sum of the rank orders obtained by all other methods. The topic ‘prevention of cross-infection’ had the highest overall rank position.Conclusion:  It is concluded that the four applied methods appeared to provide a consistent ranking of potential topics. In view of the fact that the questionnaire method is generally applicable, this method should be preferred for assessing dentists' preferences for topics to be considered for the development of clinical practice guidelines.

    Assessment of diagnostic accuracy in caries detection: an analysis of two methods (1993)

    Notes: Abstract – The quality of a diagnostic tool for caries detection is usually evaluated by quantification of observer performance using sensitivity and specificity values calculated from data obtained from ordinal caries depth rating scales. The application of Receiver Operating Characteristic (ROC) analysis has been restricted to the use of confidence rating scales. The aim of this investigation was to study the appropriateness of ROC analysis using caries depth ratings by comparing sensitivity and specificity values to parameters of diagnostic performance obtained by ROC analysis. In two recent reports, sensitivity and specificity values were utilized to express diagnostic accuracy of observer performance from specified caries diagnostic systems. The raw data from these investigations were subjected to ROC analysis in the current study. The results illustrated that ROC analysis, producing estimates of sensitivities for all specificities, yielded more comprehensive measures of diagnostic performance than single values for sensitivity and specificity. In particular, the area under the ROC curve constituted a clearly interpretable parameter representing the quality of diagnostic performance.
