Filter by:The goal of this randomized clinical trial is to compare immediate placement of an overlay after root canal treatment with delayed placement of the overlay leaving the tooth one week in infra occlusion. The main question it aims to answer are: type of study: clinical trial participant population/health conditions: patients more that 18 years old who need a root canal treatment in posterior teeth with antagonist teeth. question 1: postoperative pain after 6 hours question 2: postoperative pain after 12 hours question 3: postoperative pain after 24 hours question 4: postoperative pain after 48 hours question 4: postoperative pain after 72 hours If there is a comparison group: Researchers will compare immediate overlay placement and delayed (1 week) overlay placement after root canal treatment to see if there is more pain in one group than in the other.
Evalaution of clinical success of secondary treatment for total 40 permanent incisors with failed root canal treatment with apical radiolucency. Twenty of of these permanent incisors will be treated with regenerative endodontic treatment(RET) with platelets rich fibrin PRF as intervention group vs. 20 incisors control group secondary treated with (RET) with induced blood clot (BC).
Calcium hydroxide is advocated as an intracanal medication for various purposes, including prevention of post-treatment symptoms. Calcium hydroxide has a pain-controlling effect at different times when compared to non-intracanal medication . Aim: The aim of the study to compare between postoperative pain after using two formulations of calcium hydroxide intracanal medication with and without iodoform .
The primary aim of the study is to compare the outcome of one vs two visits endodontics (root canal treatments) performed in general dental practice of infected (necrotic) teeth, one and four years after treatment. Secondary aims are to compare the root filling quality and the frequency of complications for both treatment modalities. A pilot study will identify the shortcomings of the protocol, which will be revised accordingly. A multi-center study in several clinics from five counties throughout Sweden is planned. Consecutive eligible patients (see inclusion and exclusion criteria) with one tooth each will be included. The study sample size calculation was based on a judgement that a minimal worthwhile effect of less than 10% was not clinically relevant. The presumption was that successful outcomes would be of 75% and 65% for the different treatment arms, respectively. Three hundred and fifty six patients per group are thus needed to detect that difference as statistical significant with a power of 80% and an alfa-error of 5%. To compensate for around 30% drop-outs a number of 1000 patients will be recruited. Patients will be randomly enrolled in two arms: one in which the endodontic treatment (root canal treatment) is performed in one visit, and in the other arm in two visits. The allocation sequences for one vs multiple visit endodontics will be computer generated followed by a dark colored envelope concealed allocation. The patients will be contacted by telephone 5-7 days post-operatively, and a control visit at the clinic will be scheduled one month post-operatively to assess complications related to the treatment. A clinical control will be performed at the clinic one and four years after treatment. Intra-oral radiographs will be taken. The radiographs will be examined by two blinded and independent observers. A successful outcome is defined by clinical and radiographic normalcy. The statistical methods selected to analyse the primary outcome will be the Chi square test of 2x2 tables, or Fisher´s exact test when proportions are small and the expected value <5. The calculations will be two-tailed. Results will be considered statistically significant at p<0.05.
This study is to evaluate the effectiveness of regenerative endodontics therapy in single-rooted permanent teeth with pulp necrosis，and compare the clinical efficacy of platelet rich fibrin (PRF) and blood clot (BC) as scaffolds.
Sodium hypochlorite is a commonly used irrigation agent. However, the solution may extrude beyond the apex of tooth and cause pain during the treatment.The aim of this prospective observational investigation is to determinate the frequency of the extrusion of sodtium hypochlorite in endodontically treated teeth.
Endodontic management of traumatized immature permanent teeth with pulp necrosis is both a clinical challenge for the dental practitioners and a public health care problem. Even though there are feasible treatment procedures (such as apexification with calcium hydroxide and with Mineral Trioxide Aggregate (MTA), the long-term survival of these teeth is questionable because none of these techniques can provide continuation of root formation and thickening of the dentin walls. As a result, the immature tooth is weak and prone to fracture. Recently, regenerative endodontic procedures have gained much attention as biologically based treatment alternative to the techniques described above, but the scientific evidence is insufficient. These procedures aim to remove necrotic and damaged tissues and replace those with healthy functioning pulp-dentin complex. We plan to invite 120 patients to participate in this study. The inclusion criteria will be children between the ages of 7-19 years with traumatized permanent incisors with immature roots and open apices and pulp necrosis. Patients will be recruited from specialist clinics in Stockholm, Västerbotten and Norrbotten. The patients will be treated by specialists in endodontics and pediatric dentistry with regenerative endodontics. During a 5-year follow-up period the most important outcomes are continuous root development and healing of pulp necrosis. Severe traumatic dental injuries leading to severe complication that could result in early tooth loss can have a severe impact on oral health related quality of life. Therefore, regenerative endodontics can have beneficial effect treating these teeth.
Revitalization of Young Immature Permanent Teeth With Necrotic Pulps Using Autologous Stem Cells from Human Exfoliated Deciduous Teeth
Deep carious lesions will encounter the dentist with the challenge of selecting a treatment method that could avoid the pulpal exposure and maintain the pulp vitality.Conventional restorative treatments suggest complete removal of the caries in one visit which could cause pulpal exposure in 53% of the cases which in next step needs pulpotomy, pulpectomy or Root Canal Therapy (RCT). Stepwise Excavation(SE)is an old concept but has been researched recently to reduce the possibility pulpal exposure during the removal of the lesion. Contrary to Indirect Pulp Capping (IPC), in this technique only the central infected part of the caries is removed in first visit and the rest of the caries will be lined by a suitable material to suppress the remained cariogenic biomass and seal the cavity. This will help the pulp to defend and survive. After a period, the cavity is re-opened and the rest of the caries which is darker, harder and with less bacteria will be removed and the tooth is restored permanently.The aim of this study was to compare the effect of different lining materials in clinical and radiographical symptoms in stepwise excavation without re-enter after one year.
