Introduction: The aim of this study is to evaluate the fluidity characteristics of the root channel patch (epoxic and bioseramic-based) with two different content in three different temperature values (0, 25 and 140 oC). Method: Bioseramic and epoxy resin-based root channel paths are placed on the glass layer with the help of insulin (tuberculin) spray that will be 0.05 ml. A second glass layer of 20 gr weighing 180±5 seconds after the application was placed in a way that mediates the shell (50x50x3,2 mm). Then a weight of 100 grams was placed on the glass, the pot was applied with a total weight of 120 grams. For the measurement of the fluidity of the spread patch, the minimum and maximum diameter of the patch spread to the glass surface was measured with the help of the digital patch. The average of the data received. Results: Epoxy resin-based root channels show fluidity at 0 oC, while bioseramic-based fluidity show at 140 oC. Epoxy resin-based root channel patch shows a high fluidity value at 140 °C; bioseramic patch shows at 25 °C. According to the data obtained in our study, at 0 °C and at 25 °C, the epoxy-based root channel shell, the bioseramic-based root channel shell, has similar fluidity properties (p>0,05). But at high temperatures (140°C) the fluidity of epoxy-based root channels is increased, while the fluidity of bioseramic-based root channels is significantly decreased (p<0,05). The result: Epoxy resin-based pipe increases the fluidity at 140 oC, while bioseramic-based pipe fluidity decreases at 140 oC. According to this, in cases where high heat root channel filling techniques are used, we believe that it would be more suitable not to prefer bioseramic-based patches.

Method: Bioceramic and epoxy resin based root canals were placed on the glass layer with the insulin (tubercule) syringe in an amount of 0.05 ml. After 180 ± 5 seconds from the application, a second glass layer (50x50x3. 2 mm) weighing 20 g was placed on top of the sealer. Then a weight of 100 gr was placed on the glass. Thus, a total weight of 120 gr was applied to the sealer. The minimum and maximum diameter of the sealer that spread on the glass surface was measured with a digital caliper to measure the flow of the sealer. Results: The epoxy resin-based root channel sealer showed the lowest flow value at 0 oC, and the bioceramic-based root channel sealer showed the lowest flow value at 140 oC. According to the results in our study, flow values showed no statistical difference between groups at 0 oC and 25 °C (p> 0.05). However, when the temperature was increased (140° C), the flow of epoxy resin-based root channel sealer increased, while the flow of bioceramic-based root channel sealer decreased significantly (p <0.05). Epoxy resin-based root channel sealer showed the highest flow value at 140 °C. Conclusion: Epoxy resin-based root channel sealer has increased flow value at 140 oC, whereas bioceramic based root channel sealer flow value has decreased to 140 oC. Accordingly, in cases where high-temperature root channel filling techniques are used, it is advisable to consider the results of our study Key Words: Bioceramic based root channel sealer, epoxy resin based root channel sealer
