The aim of the present study is to clinically compare the incidence of postoperative pain after root canal preparation using TruNatomy system and HyFlex Electrical Discharge Machined (EDM) rotary system in asymptomatic necrotic mandibular molars.
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.
This is a randomized, prospective, double-blind, controlled clinical trial designed to evaluate 3 distinct clinical approaches used during endodontic therapy: Group 1- Root canal treatment in single visit (RCT-SV); Group 2- Root canal treatment in two visits with intracanal dressing (RCT-TVWD); Group 3- Root canal treatment in two visits without intracanal dressing (RCT-TVWOD). A total of 210 adult patients ages 18 to 60 years, with at least one tooth diagnosed with asymptomatic apical periodontitis and periradicular lesion will be randomized and will undergo one of the types of clinical approaches during endodontic therapy. Patients' postoperative pain levels will also be recorded in periods of 24, 48, 72 hours and 7 days. Subsequently, clinical findings and long-term follow-up evaluations, with periradicular repair will be performed by periapical radiograph and computed tomography (cone-beam) at 6th, 12th and 24th months.
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.
In this observational, retro-prospective, and multicenter PMCF clinical investigation, Biodentineā¢, an active dentine substitute for professional dental use only, is evaluated at 10 years post-treatment, in its endodontic indications as followed: - Repair of root or furcation perforations. - Repair of root resorptions (internal and external). - Root-end filling in endodontic surgery (retrograde filling). - Apexification (tooth with open apex). - Revitalization procedure by means of revascularization. Evaluation is done through a 10-year post-treatment follow-up with collection of radiographic, clinical examination and safety data.
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.
