Retention of knowledge after the electronic distance course after 12 months is close to 67%. Other results indicate that we can expect better retention of knowledge from independent, responsible, and positively motivated students who can easily operate information technologies.

Effects of covariates responding significantly differently on different scales should not be summarized using an overall univariate analysis, using paired score differences averaged over all items. Such effect summary would be misleading. In the present study, significant implant-related improvements in OHRQoL were observed on both the aesthetic and FS in patients with at least one implant in the front dental area.

AbstractOral health-related quality of life (OHRQoL) is multifaceted and involves many factors. One of them is the use of dental implants. It was the aim of our study to assess whether implant therapy might improve OHRQoL. We consulted patients with at least one Astra Tech implant. Each patient completed oral health questionnaires, which were then statistically evaluated using the Wilcoxon signed-ranks test and Analysis of Covariance from a functional and aesthetic point of view. Differential response on individual scales was assessed using multivariate approach. All twelve marginal Wilcoxon tests showed an overall improvement in OHQoL (α = 0.05). On the aesthetic scale, OHRQoL was found to be associated with marital status, aesthetic reasons for undergoing surgery and number of front teeth replaced by implants. On the functional scale, three covariates were statistically significantly and appeared to have affected the levels of OHRQoL. The most significant explanatory effect was observed for the number of front teeth replaced via implantation, followed by the presence of chewing problems. Marital status was also found to have significantly affected the OHRQoL functional scale. Significant implant-related improvements in both scales were observed in patients with at least one implant in the front dental area.

Abstract:Objectives:The palatal angle is an important angle of the craniofacial complex. It is signifi cant for the diagnosis of craniofacial disorders mainly for nasopharyngeal soft-tissue patterns. Background The dentists and otorhinolaryngologists use this relationship to establish proper treatment mechanics and evaluate facial profi le. The aims of this study were to provide comparative cephalometric analyses of historical and contemporary skulls. Materials and method:A total of 190 cephalograms of 2 groups of subjects were evaluated. Dolphin Imaging 11.0 -Cephalometric Tracing Analysis was used for the analysis. Unpaired two-tailed t-test assuming equality of variances was used for all variables (at the signifi cance level p = 0.0001). Results: The modern forensic skulls had larger palatal angle at average value of 8.60 degrees ± 4.35, than that of archeological ones, the average value of which was 6.50 degrees ± 3.92. The difference was found significant. Unpaired two-tailed t-test assuming equality of variances showed that historical and contemporary skulls had statistically signifi cant results. The difference was -2.09 with standard error of 0.60 (95% confi dence interval from -3.29 to -0.89). Two-tailed probability attained value of P was less than 0.0001. Conclusion:The difference between both groups was found signifi cant. An increase in the palatal angle can be directly connected with anterior rotation of upper jaw (Tab. 2, Fig. 5, Ref. 19).Text in PDF www.elis.sk.
