Evaluation of Postoperative Pain and Success Rate Between Lateral Condensation and Warm Vertical Obturation Techniques

Brief Summary Postoperative pain is a common complication following root canal treatment, particularly in necrotic teeth with asymptomatic apical periodontitis. Although obturation technique has been suggested as a contributing factor to postoperative discomfort, direct clinical comparisons between commonly used methods remain limited. Cold lateral condensation has traditionally been considered the standard obturation technique, while warm vertical obturation systems such as Obtura II have gained popularity due to their potential for improved adaptation of gutta-percha. This randomized controlled clinical trial aims to compare postoperative pain experience and treatment outcomes following cold lateral condensation and warm vertical obturation in single-rooted necrotic teeth. Postoperative pain will be assessed during the early healing period, along with patient-reported outcomes and short-term clinical and radiographic healing. The results of this study are expected to provide clinically relevant evidence to support evidence-based obturation technique selection and improve patient comfort in endodontic practice.

Evaluation of Pain Relief and Bacterial Reduction After Using Calcium Hydroxide With Mesoporous Silica Nanoparticles as an Intracanal Medicament in Necrotic Mandibular Molars: A Randomized Controlled Clinical Trial

This study compares how well different root canal medications reduce pain and bacteria after treatment of lower molar teeth with necrotic pulp. It tests whether adding mesoporous silica nanoparticles-antibacterial particles-to calcium hydroxide makes the treatment more effective. Forty-two adult patients will be randomly assigned to receive either calcium hydroxide alone, nanoparticles alone, or a mix of both for one week during root canal therapy. measure patients' pain levels after 6h,12h,24,48h and 72 hours from treatment and the number of bacteria before and after treatment to see which method gives the best results. The goal is to make root canal treatments more comfortable and successful for future patients.

Evaluation of Different Medicaments in the Management of Necrotic Primary Molars by Lesion Sterilization and Tissue Repair

Management of non-vital primary molars is challenging due to the natural anatomy of primary teeth, patients' young age, and their behavior toward dental treatment. A simple and effective technique such as Lesion Sterilization and Tissue Repair offers a solution to cases with poor prognosis; however, the medicaments used in this technique have some limitations. This study will evaluate three different medicaments regarding the clinical success, radiographic success, and antibacterial activity.

Maximum Occlusal Bite Force of Necrotic Permanent Teeth Treated by Regenerative Technique: Randomized Clinical Trial

Further investigation is warranted to ascertain whether the regaining of sensibility and nerve function in regenerated teeth leads to the re-establishment of the proprioceptive protective mechanism inherent in vital teeth. Hence, the primary objective of this prospective randomized clinical trial is to conduct a comparative analysis of the potential effects of pulp revascularization in comparison to conventional endodontic treatments, either RCT or apexification on the Maximum occlusal bite force (MBF) in both immature and mature necrotic permanent teeth. Methods: Upon satisfying the predetermined criteria for inclusion, a total of 184 patients will be recruited for this prospective clinical trial. The study will consist of two groups, specifically Group I: Mature teeth and Group II: Immature teeth, with a sample size of 92 participants in each group. The participants will be assigned randomly to one of the two treatment modalities per group. Group I: will undergo treatment with RCT/revascularization, while Group II will receive MTA plug/revascularization encompassing both mature (n=92) and immature teeth (n=92). MBF will be measured on the selected necrotic teeth prior to clinical intervention, this measurement will be conducted using a portable occlusal force gauge (GM10). Following the completion of therapy, MBF measurements will be repeated at 6 and 12 months to assess long-term outcomes. Subsequently, the collected data will undergo comprehensive analysis.

Efficacy of Integrated Nano-technology in Revascularization of Immature Necrotic Teeth

This trial aims to study the effect of photoactivated disinfection using Diod laser (810 nm) to activate photosensitive nanoparticle chitosan as an endodontic irrigant versus sodium hypochlorite followed by saline and then EDTA 17% on 1) postoperative pain and 2) the success of revascularization in patients with necrotic immature maxillary anterior teeth using a randomized clinical trial design.
