Filter by:The clinical use of a flowable premixed calcium-silicate bioceramic sealer used in association with warm carrier-based/single-cone technique will be compared with epoxy resin-based sealer with carrier-based technique.
The study compares the prognosis of cases of Separated Instruments in Canals With Type II Vertucci's Classification treated with conservative approach
The purpose of this study is the assessment of vertical root fracture resistance of roots prepared with three different single endodontic rotary files in extracted human mandibular premolar roots.
It has been demonstrated that a great amount of tooth structure is lost during the prosthetic preparations of abutments for full-coverage FDPs with tooth substance removal of 63% of 73%, this aggressive loss of tooth structure usually accompanied with pain and post-operative sensitivity. In comparison with the vertical preparation technique, there is less amount of tooth substance loss. this clinical study will provide benefits for practitioners and clinicians by guiding them to choose a more conservative treatment plan with the better marginal fit, clinical performance and satisfaction for the patients on the long term. rather than other benefits like less chair time, less risk for pulp injury, less time and cost
The purpose of this study was to evaluate the clinical results produced by a manual therapy treatment combined with dry needling (MT+DN) and a manual therapy treatment (TM) versus a control (C), to normalize the altered cervico-mandibular variables after a session of root canal therapy.
The aim of this study will be to evaluate the clinical performance of polyethylene fiber reinforced resin composite restorations versus bulk fill resin composite restorations in endodontically treated teeth.
The aims of this retrospective analysis are (1) to evaluate the success rate of a non-surgical retreatment of teeth with broken file instrument into the canal using ultrasounds, microscope and a modified spinal needle, (2) to assess the outcome of the treatment if the remaining fragment was left, bypassed or removed from the root canal in terms of survival rate of the treated teeth after a 5-years follow up period.
Endodontic treatment is performed frequently which often results in weakening of tooth structure. Coronal restoration is done to restore these endodontically treated teeth. Posts have been used to retain the coronal restoration and reinforce these teeth but unfortunately posts placement results in further weakening of tooth structure. Newer contemporary core buildup materials will be used to restore coronal part of tooth without using endodontic posts and then the fracture resistance of these teeth will be evaluated. This study will be performed to evaluate the fracture resistance of endodontically treated teeth restored with newer contemporary core buildup materials. 80 recently extracted single rooted caries-free and unrestored premolars will be taken and mounted in acrylic resin blocks. Roots of teeth will be covered with light bodies of condensation silicone impression material to simulate periodontal ligaments. Class 1 and class 2 cavities will be prepared and endodontic treatment will be performed in these teeth specimens. Coronal restoration will be done with three core buildup materials (Cention-N, Zirconomer and Aristaloy Amalgam). Teeth specimens are then divided into group 1 and group 2 (class 1 cavity preparation and class 2 cavity preparation respectively) and each group is further divided into four subgroups: Subgroup A: Control group Subgroup B: Cavities restored with Zirconomer (Shofu) Subgroup C: Cavities restored with Cention-N (Ivoclar vivodent) Subgroup D: Cavities restored with Aristaloy Amalgam (Cookson) Fracture resistance of endodontically treated teeth restored with different core buildup materials will be tested by the Universal testing machine.
This randomized clinical trial compares the effects of intracanal medicaments on the incidence of postoperative pain and flare-up in asymptomatic retreatment cases.
Objectives: The aim of this study was to assess postoperative pain in prospective randomized clinical trial comparing Reciproc or hand instrument and also different obturation techniques in one visit of endodontic retreatment. Conventional root canal treatment was done to 45 patients who needed retreatment. All instruments used in this study are routinely used instrument in endodontic therapy. After completed root canal treatment, the patients asked the intense of post operative pain.
