Dental students have generally positive attitudes towards e-learning. Teachers should adopt strategies to change negative attitudes by introducing more e-learning courses in lower study years and should encourage students to use the Internet in their education and communication with teachers and colleagues.
Patients' and parents' perception of malocclusion are important in determining orthodontic treatment demand, motivation, and cooperation. The aim of this study was to investigate differences in perception of treatment need in currently orthodontically treated, previously treated, and untreated subjects. The sample comprised 3196 children and adolescents (1593 males and 1603 females) aged 8-19 years (mean age 13.0 +/- 3.6 years) from 24 randomly selected public schools in Zagreb, Croatia. Objective treatment need was assessed clinically using the Dental Aesthetic Index (DAI). Subjective treatment need was estimated separately by an orthodontic resident, the child/adolescent and his/her parent using the Standardized Continuum of Aesthetic Need (SCAN) procedure. The children/adolescents completed a questionnaire that had five questions with five-point Likert-type scale answers concerning satisfaction with dental appearance, importance of teeth for facial appearance, and malocclusion-related quality of life. Spearman correlation and logistic regression were used for statistical analysis. Associations between objective and subjective orthodontic treatment need were weak but statistically significant (Rho from 0.20 to 0.50; P < 0.05). Malocclusion-related quality of life was poorly associated with treatment need. Satisfaction with tooth appearance showed the most frequent statistically significant correlation (Rho from -0.14 to -0.35; P < 0.05), while importance of aligned teeth for facial appearance and social contacts had the weakest correlation with treatment need. Perception of treatment need was greater in previously treated subjects. Parents' perception had a low predictive value. The findings of this study show that malocclusion has more impact on emotional well-being than on function or social contacts.
An appropriate relationship of the mesiodistal (MD) widths of the maxillary and mandibular teeth favours optimal post-treatment results. The aims of this study were to determine whether there is a difference in the incidence of tooth size discrepancies among different skeletal malocclusion groups and if gender dimorphism exists. The dental casts and lateral cephalometric radiographs of 301 Croatian subjects (127 males and 174 females, mean age 16.86 +/- 2.93 years) were selected from a larger sample of records of the archives of the Orthodontic Department, School of Dental Medicine, University of Zagreb, Croatia. The subjects were from malocclusion groups according to Angle classification, with the corresponding skeletal characteristics. The MD dimensions of all teeth from first molar to first molar were measured on the dental casts using digital callipers. Statistical analysis was undertaken using Kolmogorov-Smirnov, t, and Scheffé's tests and one-way analysis of variance. A statistically significant gender difference was found in anterior ratio (P = 0.017). A significant difference in the overall and posterior ratio was observed between Class II and Class III subjects. There was a tendency for mandibular tooth size excess in subjects with an Angle Class III malocclusion and for maxillary tooth size excess in those with an Angle Class II malocclusion. The percentage of subjects more than 2 standard deviations from Bolton's means for anterior and overall ratios was 16.28 and 4.32, respectively.
This case report describes the management of a crown-root fractured maxillary right central incisor and a crown fractured maxillary left central incisor using two different techniques.A complex procedure was designed to manage this case including orthodontic extrusion to move the fracture line above the alveolar bone and surgical recontouring of the altered gingival margin. Finally, the right incisor was restored prosthodontically. Prosthetic treatment was based on performing a post and core, and all-ceramic crown on the extruded tooth. The left, less-damaged incisor was restored directly using composite resin.The treatment resulted in good esthetics and secured periodontal health. This case report demonstrates that a multidisciplinary treatment approach is a reliable and predictable option to save a tooth.How to cite this article: Ortolan SM, Strujic M, Aurer A, Viskic J, Bergman L, Mehulic K.
