A total of 24 lower first molars and 24 lower second premolars were included in this study. The distal canal of all molars received endodontic treatment. After root canal treatment, the teeth were dissected, and only the distal halves were kept. Standardized class II occluso-distal (OD) (premolars) and mesio-occlusal (MO) (dissected molars) cavities were prepared in all teeth, and premolar–molar units were created. The units were randomly distributed among four groups (n = six/group). With the aid of a transparent silicone index, direct inlay-retained composite bridges were fabricated. In Groups 1 and 2, both discontinuous (everX Flow) and continuous (everStick C&B) fibers were used for reinforcement, while in Groups 3 and 4, only discontinuous fibers (everX Flow) were used. The restored units were embedded in methacrylate resin, simulating either physiological periodontal conditions or furcation involvement. Subsequently, all units underwent fatigue survival testing in a cyclic loading machine until fracture, or a total of 40,000 cycles. Kaplan–Meyer survival analyses were conducted, followed by pairwise log-rank post hoc comparisons. Fracture patterns were evaluated visually and with scanning electron microscopy. In terms of survival, Group 2 performed significantly better than Groups 3 and 4 (p < 0.05), while there was no significant difference between the other groups. In the case of impaired periodontal support, a combination of both continuous and discontinuous short FRC systems increased the fatigue resistance of direct inlay-retained composite bridges compared to bridges that only contained short fibers. Such a difference was not found in the case of sound periodontal support between the two different bridges.}, year = {2023}, eissn = {2073-4360}, orcid-numbers = {Braunitzer, Gábor/0000-0001-8983-5175; Garoushi, Sufyan/0000-0001-9457-2314; Fráter, Márk Tibor/0000-0002-0365-1613} } @article{MTMT:32722731, title = {The biomechanical effect of root amputation and degree of furcation involvement on intracoronally splinted upper molar teeth – An in vitro study}, url = {https://m2.mtmt.hu/api/publication/32722731}, author = {T.

I. restorations or class II. mesio-occluso-distal (MOD) indirect overlay restorations with cuspal coverage. Methods Sixty sound maxillary first molars were collected and randomly divided into four groups. In Groups 1 and 2, MOD cavities were prepared and all cusps were reduced by 2 mm, whereas in Group 3 and 4, only a conservative Class I. cavity was prepared. Subsequently, root canal treatment was performed and the mesio-buccal roots were amputated. Groups 1 and 2 were restored with indirect composite overlay, while Groups 3 and 4 received direct composite fillings. After restoration, teeth were embedded as follows: Groups 1 and 3: normal bone level, Groups 2 and 4: furcation involvement. The specimens were submitted to static fracture resistance testing. Fracture thresholds and fracture patterns were measured and evaluated. Results Group 1 had the highest fracture resistance (2311,6 N) among the restored groups and showed statistically significant difference compared to Group 2 (p = 0.038) and Group 4 (p = 0.011). There was no statistically significant difference in terms of fracture resistance between the rest of the groups. In terms of the fracture patterns, Group 3 was characterized by the highest percentage (60%) of mostly favorable fractures, while the rest of the groups showed predominantly unfavorable ones. Conclusions The amount of periodontal support seems to influence the fracture resistance of root-amputated and restored maxillary molars.}, keywords = {Overlay; Fracture resistance; Furcation; Short fibre-reinforced composite; Bone support}, year = {2019}, eissn = {1472-6831}, orcid-numbers = {Braunitzer, Gábor/0000-0001-8983-5175; Baráth, Zoltán Lajos/0000-0003-0636-6313; Fráter, Márk Tibor/0000-0002-0365-1613} } @article{MTMT:31132533, title = {The key elements of conducting load-to-fracture mechanical testing on restoration-tooth units in restorative dentistry}, url = {https://m2.mtmt.hu/api/publication/31132533}, author = {Szabó, P.
