Filter by:The aim of this study is through a randomized clinical trial, double blind, splithmouth, evaluate the success rate (post or dental crown displacement; fracture of the core/post/crown; marginal integrity and absence of endotontic alterations) of definitive indirect crowns un endodontically treated teeth. The composition of the resin cement (with and without mineral trioxide aggregate) will be evaluated. Data will be collected, tabulated and submitted to statistical analysis.
Caries disease is still the leading cause of severe tooth decay. Since this can lead to tooth loss, it is important that appropriate treatment is advised to help prevent damage and maintain tooth health. Faced with major coronary destruction, several times it becomes necessary to perform the endodontic treatment, aiming to maintain the element in the buccal cavity for longer. It is known that an excellent restorative treatment with poor endodontic treatment and vice versa has a direct impact on the (in) success of the treatment. In this context, the proper cleaning of the root canals is highlighted, aiming the removal of bacteria and toxins. There are several cleaning methods described in the literature, but it is not yet known which would be the most effective in the removal of these contaminants. In this double-blind randomized clinical trial, patients who need and meet the inclusion criteria will undergo endodontic treatment in two different root canal cleansing techniques (passive ultrasonic cleaning and cleaning with the XP Endo device). Patients will be monitored annually after finish your endodontic treatment to evaluate the periradicular repair and the quality of endodontic treatment.
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.
In this study the effect of different engine-driven nickel titanium (Ni-Ti) instrumentation systems (OneShape, Revo S and WaveOne) on postoperative dental pain in patients with asymptomatic teeth after a single-appointment root canal retreatment was evaluated.
Caries disease is still the leading cause of severe tooth decay. Since this can lead to tooth loss, it is important that appropriate treatment is advised to help prevent damage and maintain tooth health. Faced with major coronary destruction, several times it becomes necessary to perform the endodontic treatment, aiming to maintain the element in the buccal cavity for longer. It is known that an excellent restorative treatment with poor endodontic treatment and the inverse has a direct impact on the (in) success of the treatment. In this context, the proper cleaning of the root canals is highlighted, aiming the removal of bacteria and toxins. Acceptable restorations are those that provide adequate reestablishment of anatomy, function, proximal contacts, and occlusal stability. Traditionally, indirect restorations would be indicated in cases of extensive coronary destruction, because it was believed that they would present greater resistance and longevity when compared to direct restorations. However, contemporary dentistry admits that, thanks to adhesive and conservative principles, this difference between direct and indirect procedures in terms of longevity is not significant. The classic restorative procedure in cases of endodontically treated teeth with great loss of coronary structure involves the use of intraradicular retainers, followed by the creation of core and restoration through total crowns. Removal of healthy tissue for the use of posts can weaken the remaining dental structure and increase the risk of root perforations. In this sense, endocrown restorations show superiority when compared to those made with intraradicular retainers. Although the indications are favorable for the use of endocrown restorations, the clinical evidence available on the subject is still scarce. In this double-blind randomized clinical trial, patients who need and meet the inclusion criteria will will be allocated to one of the three restorative groups available, being endocrown restoration in semi-direct composite resin, direct restoration in composite resin retained on the post and ceramic crown retained in the post. Patients will be monitored annually after completion of restorative treatment outcome. In addition to treatment longevity, other secondary outcomes will be evaluated, such as patient satisfaction, impact on quality of life and cost-effectiveness of the proposed treatments.
This study will be a controlled, randomized, parallel group trial where the survival rate of direct and indirect restorations on removable partial denture abutment teeth will be assessed. For this, individuals with widely destroyed teeth and need for endodontic treatment, with at least one remaining dentin wall, adjacent to edentulous spaces in Kennedy Classes I and II will be selected. After the minimum period of one year the teeth will be reassessed through clinical and radiographic examination annually. All patients will receive oral hygiene instructions, caries disease control and endodontic treatment according to the need of each case. Prior to post cementation, patients will receive endodontic treatment through routine techniques that include use of rubber dam, mechanized instrumentation with NaOCl 2%, gutta percha and endodontic cement filling and condensation by the McSpadden technique. The preparation for post space will be done with a specific bur compatible with the diameter of root canal, and the same preparation cast post and cores. The glass-fiber posts (will be cleaned with 70% alcohol and receive silane application. The clinical protocol for direct restoration and confection of the composite resin core will occur in the same way, using the same materials: the dental structure will be etched with 37% phosphoric acid and rinsed, followed by the adhesive system and fabrication of the restoration by incremental technique according to the manufacturer's recommendations. It is important to emphasize that the direct restorative procedure will be carried out in the same consultation of the glass-fiber post cementation. In order to make the cast metal cores, the indirect impression technique will be done with prefabricated pins associated with addition silicone. In this technique, the lightweight material will be inserted into root canal and then, the pin will be introduced into the canal. Next, a prefabricated tray with the heavy and light material will be positioned for removal of the assembly, being removed after the setting time determined by the manufacturer. The mold obtained will be sent to the dental technician for cast post and core fabrication. All posts will be cemented under rubber-dam isolation using self-adhesive resin cement. In teeth where randomization is a metalceramic crown, first the composite resin or metal core will be prepared with a 3216 drill, in order to obtain 1.5mm wear on the proximal and free faces and 2mm on the occlusal surface. The margin design in form of a chamfer, preferably at the gingival level whenever possible. The impression procedure will be carried out using a molding cap and polyether, which will be removed in a tray with irreversible hydrocolloid. A temporary crown will also be made for the patient. The metallic infrastructure will be tested in order to verify its adaptation and transferred in irreversible hydrocolloid molding for later ceramic application. After application of the ceramic, the laying and adaptation of the prosthetic piece will be conferred, being the crown luted with self-adhesive resin cement. Once the restoration / crown of the abutment tooth has been made, the treatment will continue with the preparation of the removable partial denture. The teeth will always be prepared in the mesial proximal area. The delivery of the removable partial denture will be considered the baseline of the study. At this moment, the necessary adjustments and subsequent control of the prosthesis will be made after 24, 72 hours, a week and 15 days in order to check for possible flaws. After 6 months and 1 year of delivery of the removable partial denture, all patients will be recalled for clinical and radiographic evaluation of prostheses / restorations and oral hygiene conditions. This monitoring will be conducted by two evaluators until the end of the trial. All clinical procedures will follow pre-established protocols and the data of each patient and intervention will be recorded in the individual patient file.
Maintaining Apical patency during root canal treatment is a widely followed methodology in modern endodontic treatment protocols. It involves passing of a small #08 or #10 K file through the apical foramen during root canal shaping without widening it. it is done to keep the foramen and apical thirds of root canal free of debris. proponents of the procedure claim it to improve irrigation; provide better tactile feedback; reduce the chances of procedural errors; reduce transportation and reduce pain following root canal procedures. however, there is no clinical trial which specifically evaluates the effect of apical patency on outcome of root canal procedure. hence this study was designed to evaluate the effect of apical patency on outcome of root canal treatment.
In this clinical trial the investigators will evaluate an alternate treatment option, which was developed for teeth with incomplete roots, called Regenerative Endodontic Procedure (REP). This treatment works by harnessing the blood clot formed within the root canal from tissues surrounding the root as a scaffold for stem cells. These cells could help to increase the thickness and length of the root canal walls resulting in root end maturation. Results from the 50 participants who will receive the REP treatment will be compared with findings with historical data.
1. RATIONALE All-ceramic endocrowns are bonded to the tooth using adhesive resins creating strong bonds to the tooth structure resulting in strengthening effect and reducing the need for post and core. various CAD/CAM materials can be used for the fabrication of endocrowns including lithium-disilicate reinforced glass-ceramics, feldspathic ceramics, in ceram alumina and in ceram spinell as well as hybrid ceramics and composites. Fewer data are available on the clinical performance of the different materials used for endocrowns. With the rapid innovation in the dental restorative materials clinicians are sometimes confused when selecting the best restorative material to restore an endodontically treated tooth with an endocrown. This is due to lack of data with regard to clinical performance of these restorations as well as the degree of patient satisfaction. 2.
