Filter by: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.
Clinical performance of indirect adhesive restorations - onlays, overlays- luted with light-cured composite resin will be evaluated.
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.
The aim of this study is to evaluate the clinical behavior of zirconia crowns in dental esthetic zone with vertical versus conventional preparation techniques using a new gradient technology monolithic zirconia (5Y-TZP/3Y-TZP).
This study is a prospective randomized controlled study of patients who come to the University. The aim is to evaluate the success rate of treatment and retreatment of canals using BioRoot ™ RCS cement compared with AH Plus up to 6 years of follow-up. The null hypothesis is that there will be no statistically significant differences in rates of successful treatment of root canals filled with BioRoot ™ RCS compared to gutta-percha and AH Plus sealer.
This study is a prospective randomized controlled study of patients who come to the University and non-surgical root canal retreatment is considered as the election of choice in presence of periapical disease. The aim is to evaluate the success rate of non-surgical retreatment performed in one compared to two visit treatment up to 10 years of follow-up. The null hypothesis is that there will be no statistically significant differences in rates of success, when performing root canal non-surgical retreatment in one or two visits.
Clinical performance of indirect adhesive restorations - onlays, overlays- luted with light-cured composite resin will be evaluated over three years.
In fixed prosthodontic treatment, deflection of gingival tissues for diagnosis or making an impression is one of the important phases. Gingival displacement is defined as "displacement of gingival tissues both in vertical and lateral dimensions". Lateral retraction displaces the tissues so that an adequate bulk of impression material can be interfaced with the prepared tooth. Vertical retraction exposes the uncut portion of the tooth apical to the finish line Conventional gingival retraction cord technique may injure the healthy epithelial lining and result in postoperative gingival recession The diode laser has been used for displacing gingiva to make a definitive impression. Rather than displacing gingival tissue, it removes the epithelial lining from the sulcus. The aim of the Study is to compare between the Ultrapak retraction cord and diode laser regarding the amount of vertical and lateral retraction and patient comfort.
Objective: The objective of this study will be to evaluate the effectiveness of different endodontic treatment techniques in postoperative symptoms, apical repair, longevity of rehabilitations, and oral health-related quality of life. Methods: This prospective, randomized, double-blind clinical study was approved at the Research Ethics Committee (nº 2.353.996) and will consist of a sample of 350 patients who will be attended in the clinics of the Federal University of Fluminense/Institute of Health of Nova Friburgo (UFF/ISNF), in which they will be selected based on eligibility criteria. Patients aged up to 18 years, with teeth with necrotic pulps and radiographic evidence of periapical lesion will be included. These patients will be randomly divided into 8 groups: I (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, lateral condensation filling with MTA Fillapex; II (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, photobiomodulation (aPDT and LLLT), lateral condensation filling with MTA Fillapex; III (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, chlorhexidine as irrigant, lateral condensation filling with MTA fillapex; IV (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, lateral condensation filling with AH Plus; V (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, cryotherapy with saline solution, lateral condensation filling with MTA Fillapex; VI (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, cryotherapy with saline solution, lateral condensation filling with AH Plus; VII (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, ozone therapy, lateral condensation filling with MTA Fillapex; VIII (35 patients): unirradicular teeth will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, sodium hypochlorite as irrigant, ozone therapy, lateral condensation filling with AH Plus; IX (35 patients): molars will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, conventional irrigation with sodium hypochlorite, lateral condensation filling with MTA fillapex; X (35 patients): molars will be submitted to endodontic treatment with foraminal enlargement, instrumentation with reciprocating rotation, passive ultrasonic irrigation with sodium hypochlorite, lateral condensation filling with MTA fillapex. The analysis of the postoperative symptoms will be performed by the visual analog pain scale at 1th, 2th, 3th, 4th, 5th, 6th, 7th, 14th and 30th days and by the clinical evaluation of edema in 48 and 72 hours. The periapical lesion repair will be evaluated clinically and radiographically at 3, 6, 12, 18 and 24 months. The longevity of rehabilitations will be performed clinically and radiographically for 24 months. In addition, patients will respond a quality of life questionnaire (OHIP-14) on the day of endodontic treatment, on the 7th day and on the 30th day. Data analysis: The data will be inserted into a statistical program (SPSS), obtaining the frequencies of the characterization variables of the sample. The appropriate tests will be used to compare the means of the groups.
extrusion of infected dentin into the periapical tissue has been suggested as a major source of pain after endodontic treatment. Although debris extrusion is an inevitable finding even when instrumentation is limited to the confines of the canal, different armamentarium seem to be associated with different amounts of debris extrusion. Studies on the effect of various rotary files on post-endodontic pain are very few and have yielded conflicting results with some favoring full-sequence and others leaning towards reciprocal rotary systems. This study aims at assessing the intensity of post-endodontic pain following two different rotary systems, Reciproc and race. Methods: in this single-blind, parallel-grouped randomized clinical trial a total of 150 otherwise healthy patients aged between 20 to 50 years old with a pulpal status of irreversible pulpitis for one tooth in the upper or lower molar region were analyzed. A clinician performed the endodontic treatment in two groups, a group instrumented using race and a third group with instrumentation performed using Reciproc rotary systems.
