Root Canal Treatment

A prospective, parallel-group, randomised, post-market clinical follow-up investigation evaluating the performance and safety of the modified formula of the AH Plus Jet® Endodontic Sealer (also referred to as ES) and the predicate AH Plus Jet® Root Canal Sealing material (also referred to as RCS). Around 150 teeth will be randomly assigned to receive either ES or RCS root canal treatment using the single-cone technique. A maximum of 2 teeth per participant will be included and "tooth" will be considered the statistical unit and hence considered independent even if the teeth are in the same participant. Participants will be followed up for a period of 24 months to assess the outcomes.

To evaluate and compare postoperative pain and extrusion of sealers following root canal treatment using NeoSealer Flo and CeraSeal bioceramic sealers

The goal of this clinical trail is to compare the analgesic effect of endo-ice and ice-sticks in reducing intra-operative pain during pulpectomy in molars with Symptomatic Irreversible Pulpitis. Principal Investigator will perform the procedure and outcome assessor will interview the participants as well as fill the pre-operative questionnaire. The patient will be instructed beforehand on how to score their pre-operative, intra-operative and post-operative intensity of pain according to Visual Analogue Scale.The Anxiety level of patient will also be recorded according to the Corah's Dental Anxiety Scale questionnaire and their level of anxiety before and after the intervention will be recorded by the outcome assessor. The principal investigator will perform all endodontic procedures, with the outcome assessor blinded to the cryotherapy method. Prior to administering IANB, a topical anesthetic gel will be applied. A 27-gauge needle will deliver 1.8 ml of 2% lidocaine with 1:100,000 epinephrine at a rate of 1 ml/min. After a 5-minute wait, anesthesia effectiveness will be confirmed through electric pulp testing (EPT) on a neighboring tooth, with two consecutive negative responses confirming success. Once adequate anesthesia is confirmed, an access opening will be made under rubber dam isolation for the procedure. 1. CONTROL GROUP: After access opening and complete de-roofing of the pulp chamber, pulpectomy of the inflamed pulp will be performed under the given effective IANB with no additional intervention to control intra-operative pain. 2. ENDO-ICE GROUP: After access opening, pulp will be exposed and de-roofing will be performed. Endo-ice with the help of cotton pellet will be applied inside the pulp chamber for 2min (8 consecutive applications, 15sec each) and pulpectomy of the inflammed pulp will be performed immediately. 3. ICE-STICKS GROUP: Following the access opening and complete de-roofing of pulp chamber, four ice sticks will be placed inside the pulp chamber for 2 minutes (30 seconds each, using tweezer). Subsequently, pulpectomy of the inflamed pulp will be performed immediately. Patients will be asked to rate their level of pain to the outcome assessor at four specific intervals during the trial, i.e., pre-operative (before local anesthesia), pre-operative (after local anesthesia), during pulpectomy and immediately after pulp extirpation and it will be recorded in a proforma by the blinded outcome assessor. Pain and Anxiety Scores will be compared to asses either cryotherapy or which method of cryotherapy found to be effective in reducing intra-operative pain.

The purpose of this study is to understand and learn better the efficacy of GentleWave and obtain histological evidence of the efficacy of this new technology done in-vivo
