Objective: In this study, researchers used two different adhesives to determine which ones had the strongest push-out connection between resin composite posts and primary teeth's intracanal dentin. Methods: Fifty primary lateral incisors were split into two groups (n = 25) and treated with either Adper Single Bond 2 (ASB group) or Clearfil SE Bond 2 (CSE). Resin composite was used to fill the canal in the root's coronal one-third. A universal testing equipment was used to conduct the push-out evaluation. The data was analyzed using t-test. Results: Strengths of push-out bonds were found to be significantly different amongst the two groups using t-test (p=0.000). The mean±S.D push-out bond strength of the samples in ASB group was 8.41±4.83 Mpa, while mean±S.D push-out bond strength of the samples in CSE group was 14.21±4.03 Mpa. Most failures were adhesive, and there was no difference (p=0.327) in the fracture mode distribution between bonding agents. Conclusion: In terms of push-out bond strength, CSE group was clearly superior to ASB group. When placing resin composite posts in primary anterior teeth, it is advised to utilize a universal adhesive system and self-etch adhesives from the sixth generation. Due to their simplicity of use, reduced technical sensitivity, and reduced number of required clinical processes, bonding agents may be a desirable choice for repairing primary teeth with short resin composite posts.

Objective: The purpose of this research was to evaluate the effectiveness of various root canal sealers in reducing postoperative pain and the need for analgesics. Methods: The asymptomatic necrosis and apical periodontitis of 60 single-rooted teeth were studied by randomly assigning them to 2experimental groups (n=30) according to the root canal sealer: AH Plus and MTA Fillapex. Two appointments were needed to complete the endodontic treatment, and calcium hydroxide was employed as the intracanal dressing. The patients were asked to assess the severity of their discomfort as no pain, slight and moderate pain. After 24 hours, 48 hours, and 7 days, patients rated their discomfort on a scale from 1 to 4. The use of pain relievers was also documented. Postoperative pain and the requirement for analgesia were compared using the t-test. Results: The Mean±S.D of the participants age in AH plus and MTA Fillapex group was 39.1±9.4 and 43±9.2 years. Overall, 62% were female and 38% were males were included in the present research. Overall, 37% of the cases (22 patients) had postoperative discomfort after 24 hours, with the number decreasing to 18% (11 patients) after 48 hours. After 7 days, no one in either of the groups had any discomfort. There were no statistically significant differences between groups in the occurrence or severity of postoperative pain or in the use of analgesics at any of the assessment points. Conclusion: Similar rates of postoperative discomfort and the requirement for analgesics were seen with the use of either AH Plus or MTA Fillapex for root canal filling.
