These results suggest that the increased prostaglandin E2 concentration, caused by endodontic treatment of teeth with large restorations, is well correlated with the intensity of postoperative pain.

Under the conditions of our study, it may be concluded that the Acroseal sealer presented the behaviour more like epoxy-based material, AH Plus, than calcium hydroxide sealer, Apexit.

Introduction: Asymmetrical activity of brain hemispheres is projected through laterality e.g. the dominance of one of the paired organs. A very important way of laterality manifestation is left-handedness. The lef-handed must solve various conflicts with their environment, so mild left-handedness usually shifts into dominant right-handedness in the early childhood, fortunately with no difficulties. Aim: The purpose of this study was to determine the number and distribution of left-handed dental students, check the possibilities and propose measures for solving the problem in their education. Material and methods: The study was conducted at Belgrade University School of Dentistry, dept. of restorative dentistry and endodontics. During two academic years, six generations of senior dental students (III, IV and V year students) completed a questionnaire, i.e. 1385 individuals were included in the survey. Results: The questionnaire revealed that out of the total number or students involved in the study 62 (4.48%) students were left-handed. The distribution of left-handed students is relatively uniform and concentrated between 4-6% of the sample. Conclusion: Even though the number of left-handed students is small, it is necessary to change conditions for their education and enable their proper development

The aim of the present study was to investigate the effects of caffeic acid phenethyl ester (CAPE) on wound healing capacity and repair of the pulp dentin complex on an experimental model. Eight young male pigs were used in this study. Arteficially preformed pulp lesions were treated either with calcium hydroxide (control group) or with CAPE powder (experimental group). The material for histological analysis was 4 and 14 weeks after pulp capping. Results of the histological analysis revealed that inflammatory reactions occurred in both groups. In the control group inflammation could be scored as mild to moderate, with a tendency to decrease during the observed period, while in the experimental group it was scored as severe in most of the specimens. Dentin bridge formation and complete reparation of the dentin-pulp complex was observed in most of the specimens of the control group, while the repair process in the experimental group was characterized by fibrous tissue proliferation. In the experimental group severe haemorrhagia, tissue oedema and dentin resorption were also observed. Based on reported results it could be concluded that capping material containing CAPE could not enhance the repair of the dentin-pulp complex, and healing of the dentin-pulp complex was characterized by scar tissue formation, rather than dentin bridge formation
