Active clinical trials for "Tooth, Nonvital"

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.

To compare the incidence of post-operative pain after single-visit versus two-visit non-surgical endodontic retreatment.

To evaluate and compare the degree of tooth discoloration in tooth crowns induced by Neo MTA versus white MTA over time. Evaluation of the effectiveness of Neo MTA as coronal plug in revascularization of immature teeth with necrotic pulp.

To evaluate the incidence and severity of postoperative pain after root canal therapy of necrotic teeth in one appointment versus two appointments using Protaper next instrument.

The elimination of pathogenic microorganisms from the root canal system is one of the main points in order to have success in endodontic treatment. The objective of this study is to perform a randomized controlled clinical trial to compare the effectiveness of success in endodontic treatment of primary teeth when combined with photodynamic therapy. Will be selected 30 primary teeth of children aged between 3 and 6 years. The teeth will be divided into two groups: group I control, which will be applied the conventional endodontic treatment and group II to be held endodontic treatment with application of photodynamic therapy. In both groups will be made microbiological evaluations before and after endodontic treatment and clinical and radiographic evaluations will be conducted in the day, 1 month, 3 months and 6 months after treatment comparing the treatment performed in both groups.

The aim of this study is to compare the postoperative pain after root canal treatment following irrigation by endodontic needle, sonic and passive ultrasonic irrigation techniques.

Coronal retention of the restoration of RCT teeth is usually compromised, thus intraradicular posts combined or not with core material may be required. The drawbacks of the conventional treatment created a necessary demand to have alternative treatment options. Among these options is the endocrown restoration. The pulpal chamber cavity provides retention and stability. Its trapezoidal shape in mandibular molars and triangular shape in maxillary molars increase the restoration's stability. The saddle form of the pulpal floor increases stability. This anatomy, along with the adhesive qualities of the bonding material, make no need for additional preparation or further use of post-involving root canals.

Nowadays Endocrowns are classified as conservative treatment modality for restoration of Endodontically treated teeth in which pulp chamber is used as a retentive resource. With the advancement in technology in the field of adhesive dentistry its use is increasing day by day in clinical practice. Acid Etchable ceramics such as lithium Disilicate based ceramics are the gold standard ceramic material used for Endocrowns. The Etchable property and the translucent character of lithium Disilicate enhance strength and esthetic property. A new material CERASMART (Force Absorbing Flexible nano ceramic CAD/CAM block) contain high density of ultrafine glass particles with 71 wt% filled nano-composite. It combines high strength and unique aesthetics. full homogeneous and even distribution of nano ceramic network lead to unique physical properties for cerasmart . Uniform scuttle (very short inter-particle distance) of silanated and bonded particles is key to delivering CERASMART's™ with high strength and acceptable level of marginal adaptation. So, it can perfectly use in posterior, anterior, inlay, onlay, and implant restorations and also enables minimum tooth reduction for more conservative restoration. Awad et al (1) found that Cerasmart showed significantly higher flexural strength and modulus of elasticity, with lower flexural modulus values compared to other groups. Also, result in smoother margins compared with other types of ceramic. So, present research will evaluate patient satisfaction, bonding properties and marginal adaptation

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.
