Differences between dental practices were visible, but they were mainly explained by differences in the way tooth wear was assessed. The GDPs experienced difficulties in the use of the assessment instrument and used it differently because the definition of the instrument was not clear enough. Therefore the results of the statistical tests are not reported. | |||||
Specifications of the measure | |||||
Data source | Clinical assessment by the GDP during consultation | ||||
Clinical assessment based on | Vertical tooth wear: score per sextant the amount of lost tooth material on the occlusal/incisal surfaces [27] 0 – no (visible) tooth wear 1 – visible tooth wear only in enamel 2 – exposed dentin and loss of clinical crown height < 1/3 3 – loss of clinical crown height > 1/3, but <2/3 4 – loss of clinical crown height > 2/3 Horizontal tooth wear: score per sextant the amount of lost tooth material on the not occlusal/not incisal surfaces [27] 0 – no (visible) tooth wear 1 – visible tooth wear only in enamel 2 – exposed dentin | ||||
Numerator/denominator | To be defined. Due to the limited time of the study only baseline measures were conducted. | ||||
Inclusion criteria | • at least one oral health examination a year • at least 2 years registered in the dental practice • permanent teeth | ||||
