Aim:The aim of this study is to compare and to evaluate sealing ability of newly introduced C-point system, cold lateral condensation, and thermoplasticized gutta-percha obturating technique using a dye extraction method.Materials and Methodology:Sixty extracted maxillary central incisors were decoronated below the cementoenamel junction. Working length was established, and biomechanical preparation was done using K3 rotary files with standard irrigation protocol. Teeth were divided into three groups according to the obturation protocol; Group I-Cold lateral condensation, Group II-Thermoplasticized gutta-percha, and Group III-C-Point obturating system. After obturation all samples were subjected to microleakage assessment using dye extraction method. Obtained scores will be statistical analyzed using ANOVA test and post hoc Tukey's test.Results:One-way analysis of variance revealed that there is significant difference among the three groups with P value (0.000 < 0.05). Tukey's HSD post hoc tests for multiple comparisons test shows that the Group II and III perform significantly better than Group I. Group III performs better than Group II with no significant difference.Conclusion:All the obturating technique showed some degree of microleakage. Root canals filled with C-point system showed least microleakage followed by thermoplasticized obturating technique with no significant difference among them. C-point obturation system could be an alternative to the cold lateral condensation technique.

There were 5800 OPGs examined, out of which 2576 were of women and 3224 were of men. Bifid mandibular canals were observed in 135 (2.3%) out of 5800 digital panoramic images. There was no statistically significant correlation found with regard to age. Bifid mandibular canals were found with a female-to-male ratio of 1:1.2. The most frequently encountered type of BMC was type II (1.34%) followed by type I (0.72%), type IV (0.15%), and type III (0.1%).

Aim:This study aimed to evaluate the efficacy of intermaxillary fixation (IMF) screws and modified arch bar.Materials and Methods:This study is a randomized clinical trial in which all participants were divided into two groups of ten in each group and designated as Group A and Group B. In Group A, IMF was achieved by the use of four to six 2×8mm stainless steel IMF screws. In Group B, IMF was achieved by modified screw arch bar.Results:In the present study, a total of twenty patients were analyzed. The average working time for Group A and Group B was 16 min and 29 min, respectively. Oral hygiene scores through modified Turesky Gilmore plaque index were calculated at immediate postoperative period and after 15 days, 30 days, and 45 days. Maximum hygiene was maintained in IMF screw group than modified arch bar group, but maximum stability was observed in the modified arch bar group than IMF screw group.Conclusion:This study emphasizes the use of IMF screws as a quick and easy method than modified arch bar. Oral hygiene maintenance was comparatively better in patients with IMF screws than those with modified arch bar. Modified arch bar was significantly stable when compared with IMF screws; therefore, for patients who require long-term IMF, modified arch bars can be a viable option, but the perforation in the original arch bar may lead to the weakening of the arch bar, and therefore the prefabricated modified arch bar would be a better option.
