NCT ID: NCT05084742 Recruiting - Clinical trials for Endodontically Treated Teeth

Long-term Performance and Safety of Biodentine™ in Patients Treated for Endodontic Indications

Start date: November 8, 2021
Phase:
Study type: Observational

In this observational, retro-prospective, and multicenter PMCF clinical investigation, Biodentine™, 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.

NCT ID: NCT05079646 Completed - Fracture Resistance Clinical Trials

An In Vitro Evaluation of Fracture Resistance of Endodontically Treated Teeth Restored With New Contemporary Core Build-up Materials

Start date: November 16, 2020
Phase: N/A
Study type: Interventional

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.

The Effect of Root-canal Medicaments on Post-operative Pain in Re-treatment Cases

Start date: March 23, 2019
Phase: N/A
Study type: Interventional

This randomized clinical trial compares the effects of intracanal medicaments on the incidence of postoperative pain and flare-up in asymptomatic retreatment cases.

NCT ID: NCT04892355 Not yet recruiting - Clinical trials for Endodontically Treated Teeth

Postoperative Pain After İntracanal Procedures

Start date: August 6, 2022
Phase: N/A
Study type: Interventional

Aim: The aim of this study is to investigate the effects of different irrigation activation systems on pain after endodontic treatment in molar teeth with irreversible pulpitis.Post-operative pain values of the participants will be recorded and evaluated with the VAS scale. Postoperative pain values of the techniques will be compared with statistical evaluation.

NCT ID: NCT04838483 Recruiting - Dental Caries Clinical Trials

Clinical Performance of Posterior Indirect Adhesive Restorations

Start date: March 1, 2021
Phase: N/A
Study type: Interventional

Clinical performance of indirect adhesive restorations - onlays, overlays- luted with light-cured composite resin will be evaluated.

NCT ID: NCT04817579 Recruiting - Clinical trials for Discoloration, Tooth

Dental Photography and Numeric Shade Quantification as a Substitute to Conventional and Instrumental Shade Matching Techniques in the Esthetic Zone

Start date: August 2022
Phase: N/A
Study type: Interventional

Visual shade matching is the most common method, in which a color standard from a commercially available dental shade guide is compared to and matched with the target tooth. However, several factors can contribute to perception errors including: different lighting variables, multiple shade systems available in the market with lack of standardization in color systems and corresponding porcelain systems, individual human variables in color perception and lack of understanding of color science. Therefore, in order to eliminate the uncontrolled variables during the color matching process, instrumental methods have been developed. Spectrophotometric measurement methods employing computer calculations, based on color science and theories, allow quantitative evaluation which is objective and appears to be more accurate. However, extremely high costs, relatively low performance with respect to agreements of the computer-aided devices, and edge loss error make it less acceptable. One of the most powerful tools in communicating with both patients and dental ceramists is digital photography. Hence, this study is designed to explore the possibilities of a novel approach to shade management (eLABor_aid) utilizing a photocolorimetric (PCM) method and subsequent shade formulation without the use of stock shade guides in comparison to well-known visual and instrumental methods. The aim of the study is to evaluate the accuracy of digital photography combined with shade analyzing software (eLAB) in optimizing shade matching when compared to conventional and instrumental methods of shade selection. A Null Hypothesis is suggested where no significant difference regarding shade selection between eLAB protocol, conventional and instrumental methods will be found.

NCT ID: NCT04805281 Recruiting - Clinical trials for Endodontically Treated Teeth

Wear Behavior of Milled Posterior Crowns Fabricated From the New Monolithic Zirconia 5Y-TZP/3Y-TZP Compared to Lithium Disilicate

Start date: August 1, 2021
Phase: N/A
Study type: Interventional

In-vitro studies do not represent the actual masticatory environment and cannot simulate the intricate chewing pattern. Hence, there is a need for an in vivo study evaluating the wear potential of the newly introduced strength - color gradient multilayered zirconia IPS e.max ZirCAD Prime (5Y-TZP/3Y-TZP) and compare it to Lithium Disilicate IPS e.max CAD which has proven to have favorable wear patterns.

NCT ID: NCT04789343 Completed - Post Operative Pain Clinical Trials

The Effect of Instrumentation and Obturation on Postoperative Pain in Retreatment

Start date: March 10, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT04738526 Not yet recruiting - Clinical trials for Endodontically Treated Teeth

One Year Clinical Evaluation of Shade Matching and Patient Satisfaction of New Gradient Technology Monolithic Zirconia (5Y-TZP\3Y-TZP) Compared to Lithium Disilicate Crowns in Dental Esthetic Zone

Start date: March 1, 2021
Phase: N/A
Study type: Interventional

Although zirconia is widely used for fabrication of restorations, the 3Y-TZP zirconia where limited for posterior region for its high strength and bad esthetic. While the 5Y-TZP zirconia is limited for the anterior region due to its good esthetic and low strength. For that reason, the introduction of the new gradient technology zirconia (5Y-TZP\3Y-TZP) (IPS e.max Zircad Prime) has offered a solution to solve this problem be combining the esthetic of 5Y-TZP and the high strength of 3Y-TZP. The aim of the present study is to evaluate shade matching to natural tooth and patient satisfaction of the new gradient technology zirconia (5Y-TZP\3Y-TZP) and lithium disilicate ceramic crowns.
