European Core Curriculum in Cariology for undergraduate dental students

As dental caries prevalence is still high in many populations and groups of both children and adults worldwide, and as caries continues to be responsible for significant health, social and economic impacts, there is an urgent need for dental students to receive a systematic education in cariology based upon current best evidence. Although European curriculum guidelines for undergraduate students have been prepared in other dental fields over the last decade, none exist for cariology. Thus the European Organisation for Caries Research (ORCA) formed a task force to work with the Association of Dental Education in Europe (ADEE) on a European Core Curriculum in Cariology. In 2010, a workshop to develop such a curriculum was organised in Berlin, Germany, with 75 participants from 24 European and 3 North/South American countries. The Curriculum was debated by five pre-identified working groups: I The Knowledge Base; II Risk Assessment, Diagnosis and Synthesis; III Decision-Making and Preventive Non-surgical Therapy; IV Decision-making and Surgical Therapy; and V Evidence-based Cariology in Clinical and Public Health Practice and then finalised jointly by the group chairs. According to this Curriculum, on graduation, a dentist must be competent at applying knowledge and understanding of the biological, medical, basic and applied clinical sciences in order to recognise caries and make decisions about its prevention and management in individuals and populations. This document, which presents several major and numerous supporting competences, does not confine itself to dental caries alone, but refers also to dental erosion/non-erosive wear and other dental hard tissue disorders

Intra-observer and interobserver reliability of the 'Pico' computed tomography method for quantification of glenoid bone defect in anterior shoulder instability

Objective To evaluate the intra-observer and interobserver reliability of the \u2018Pico\u2019 computed tomography (CT) method of quantifying glenoid bone defects in anterior glenohumeral instability. Materials and methods Forty patients with unilateral anterior shoulder instability underwent CT scanning of both shoulders. Images were processed in multiplanar reconstruction (MPR) to provide an en face view of the glenoid. In accordance with the Pico method, a circle was drawn on the inferior part of the healthy glenoid and transferred to the injured glenoid. The surface of the missing part of the circle was measured, and the size of the glenoid bone defect was expressed as a percentage of the entire circle. Each measurement was performed three times by one observer and once by a second observer. Intra-observer and interobserver reliability were analyzed using intraclass correlation coefficients (ICCs), 95% confidence intervals (CIs), and standard errors of measurement (SEMs). Results Analysis of intra-observer reliability showed ICC values of 0.94 (95% CI=0.89\u20130.96; SEM=1.1%) for single measurement, and 0.98 (95% CI=0.96\u20130.99; SEM=1.0%) for average measurement. Analysis of interobserver reliability showed ICC values of 0.90 (95% CI=0.82\u20130.95; SEM=1.0%) for single measurement, and 0.95 (95% CI= 0.90\u20130.97; SEM=1.0%) for average measurement. Conclusion Measurement of glenoid bone defect in anterior shoulder instability can be assessed with the Pico method, based on en face images of the glenoid processed in MPR, with a very good intra-observer and interobserver reliability

A 3D-CT scan study of the humeral and glenoid planes in 150 normal shoulders

The purpose of the study was to determine the normal three-dimensional relationship between the humeral and the glenoid plane of the individual patient. We measured the three-dimensional angle between the glenoid plane and the humeral plane (glenohumeral angle, A degrees GH) and the angle between the plane of the scapula and the plane of the glenoid (glenoscapular angle, A degrees GS) with the patient in a standardized position to the CT scan gantry. We hypothesized that a normal distribution with a small variation would exist for both angles. A total of 150 conventional CT scans of normal shoulders from patients aged between 18 and 80 years were examined and three-dimensional reconstructions were derived from it. The descriptive statistics and the variability of A degrees GH and A degrees GS were determined. The mean A degrees GH was 57.9A degrees, and the mean A degrees GS was -3.77A degrees. The overall reliability of the measurement was good. Descriptive statistics of this study confirm the normal distribution and a narrow variation of both parameters. This is the first study to determine the normal 3D relationship between the humerus and the glenoid (A degrees GH). This new three-dimensional anatomical information of the normal glenohumeral relationship and glenoid can be used to distinguish normal from pathological anatomy, as well as alternative surgical guidance especially in bony deficient glenoids
