Incidence of Postoperative Pain After Single- and Multiple-Visit Root Canal Treatment in Patients Reporting in the Conservative Dentistry and Endodontics Outpatient Department of a Tertiary Care Hospital: A Cross-Sectional Study.

This study aimed to conduct a human study to determine the incidence of postobturation pain using different parameters. In this cross-sectional study, 240 patients were included, which were equally allocated into two groups: single visit and multiple visit, 120 in each. Patients in both the single and multiple visits were further categorized into two subgroups, subgroup 1-no occlusal reduction and subgroup 2-occlusion reduction each having 60 patients. Corresponding to the type of visit, patients were followed by the role of medication into two groups, subgroup 1-both analgesics and antibiotics, subgroup 2-only analgesics, and subgroup 3-no medication. Following this approach and the criteria of the study, patients' performa was made, and based on this performa, the intensity of subjective symptoms, particularly postobturation pain, was determined using the visual analog scale (VAS). The data were then analyzed using the Chi-square test. Results were such that a single visit, no occlusal reduction, and only analgesics will be better for patients with irreversible pulpitis as chosen in the present study. Within the limitations of the present study, it can be concluded that single-sitting root canal treatment should be preferred over multiple sitting where there is no periapical inflammation; also, the occlusal reduction could be exempted from the same. To relieve the patient from postoperative pain where complete debridement is possible, antibiotics can be excluded from the regimen and only analgesics could be prescribed.

Comparative evaluation of the quality and homogeneity of different obturating systems using cone-beam computed tomography - An in vitro study.

Aim: The aim of this study was to evaluate the homogeneity and quality of different obturating systems using cone-beam computed tomography (CBCT). Materials and Methods: One hundred and twenty extracted maxillary and mandibular molars were included in this study which was decoronated first and then dissected into palatal and distal roots. After working length determination, all the roots were biomechanically prepared with ProTaper universal system. The prepared roots were evaluated using CBCT, and volumetric analysis was done. Samples were then randomly divided into three groups corresponding to the obturation method used - cold lateral compaction technique, single-cone technique, and BeeFill 2 in 1 system. After obturation, CBCT imaging and volumetric analyses were performed again to compare and analyze the amount of volume of obturation in different obturating techniques. To standardize the volume, pre-and postobturation images were superimposed. To avoid errors, for each section, measurements were repeated three times and the means were calculated. Statistical Analysis Used: The data were statistically analyzed using one-way analysis of variance, followed by post hoc test. Results: Results showed a statistically significant difference of the single cone with lateral compaction and the BeeFill system (P < 0.001). Maximum volume of obturating material was found in BeeFill at all levels - Coronal, middle, and apical, followed by cold lateral compaction and single-cone technique (P < 0.001). Conclusion: It could be concluded that the thermoplasticized obturating technique can be a better choice for obturation rather than the single cone and lateral compaction technique.
