Abstract     Background. Occlusal indices are methods for quantitative objective malocclusion assessment based on measurements of occlusal traits on study casts. The recording and measuring of a malocclusion index score intraorally, however, is for children more pleasant, less time-consuming and also less costly. After the preliminary findings of a study in eight-year-old children stating that malocclusion assessment score, recorded and measured intraorally, is as reliable as the assessment, made on study casts, we aim to assess its reliability taking into account the characteristics of permanent dentition also in fourteen-year-old children. Subjects and methods. The research was a part of the longitudinal study in Slovenia on a sample of 530 three-year-old children. At 14 years of age (mean 14,8 years; SD 0,18), a cohort of 92 children (53 girls, 39 boys) were randomly selected in a cross-sectional study. Quantitative registrations of space and occlusal anomalies were performed intraorally as well as on study casts. To evaluate agreement between clinical and study cast malocclusion assessment Kappa (K) statistics was used. Systematic bias of measurements was tested using Wilcoxon's signed sum ranks test. Intra- and inter- examiner reliability was tested using the intra-class correlation coefficient (ICC). Malocclusion traits, significant for total malocclusion severity score, were determined by regression analysis. Results. Complete agreement between intraoral and study cast measurements was found for anterior crossbite, transverse buccal occlusion, open bite and crowding (kappa = 0,81 - 1,00). Excellemt agreement was found for rotation of incisors and canines, for buccal segment relationship, overjet and axial inclination of teeth (kappa = 0,61 - 0,80). For the remainder of the traits the agreement was mo-derate: vestibular eruption of canine (kappa = 0,54), overbite (kappa = 0,48) and midline discrepancy (kapp = 0,41).
