Root canal filling material may be extruded during retreatment\u0000 through the apical foramen and cause flare-up or chronic infection. The aim\u0000 of this study was to compare the apical extrusion of gutta-percha and\u0000 resilon filling materials during retreatment using hand and rotary\u0000 instruments. Methods. Sixty extracted single-rooted teeth with single,\u0000 straight canal were selected. Canals were prepared with ProTaper Universal\u0000 rotary system to a size F2. Two groups (30 teeth in each) were filled with\u0000 gutta-percha or resilon points, respectively. In both groups teeth were\u0000 randomly divided into the three subgroups (10 teeth in each), based on the\u0000 instruments used for retreatment: Hedstrom hand files and two rotary groups-\u0000 ProTaper and Twisted File instruments. Apical extrusion was detected\u0000 visually, using a 4-degree scoring system. Mean scores were calculated and\u0000 analyzed statistically (t-test and ANOVA).

Under tested experimental conditions, the type of\u0000 canal filling material did not have significant effect on the results of\u0000 apical extrusion during retreatment. Significantly more material was\u0000 extruded in the resilon group when manual, Hedstrom file was used (1.80 ?\u0000 1.13) than rotary ProTaper (0.60 ? 0.70) and Twisted File (0.50 ? 0.71).\u0000 Conclusions.

Good physicochemical properties of endodontic materials are one\u0000 of the main preconditions for successful endodontic treatment. Modern\u0000 endodontic materials are expected to have good adhesiveness, stability and\u0000 low solubility in order to enable high-quality and permanent obturation of\u0000 the root canal. The aim of this study was to test in vitro the stability and\u0000 degree of solubility of two endodontic materials: Mineral Trioxide Aggregate\u0000 (MTA) and Gutta Flow. Materials and methods. The solubility of endodontic\u0000 materials Mineral Trioxide Aggregate - MTA (Angelus) and Gutta Flow\u0000 (Colthane) was tested by the aging method using artificial saliva according\u0000 to the prescription of Ira and Shannon. Twelve samples of single-rooted\u0000 teeth (6 MTA, 6 Gutta Flow) were used. The samples were analyzed after 7,\u0000 14, 21, 28 and 35 days.

Endodontic instruments during root canal treatment come into\u0000 contact with dentinal debris, irrigation solutions and medication agents,\u0000 which reminants should be eliminated before sterilization. The aim of the\u0000 study was to verify the effectiveness of different cleaning methods for\u0000 removing calcium hydroxide paste residues from the surfaces of the working\u0000 parts of hand instruments, as well as to propose an effective protocol for\u0000 cleaning endodontic instruments before sterilization. Material and methods.\u0000 Forty-two new hand endodontic instruments were used to remove calcium\u0000 hydroxide paste from the filled canals of extracted teeth. After\u0000 contamination with medication, they were divided into the four groups and\u0000 subjected to individual decontamination methods - mechanical, chemical and\u0000 ultrasonic, as well as a combined protocol.
