Active clinical trials for "Dental Pulp Diseases"

The purpose of this study is to compare the clinical and radiographic success of a new injectable, fast setting bioceramic root repair material (BC RRM) putty with mineral trioxide aggregate (MTA) in pulpotomy procedures of primary teeth. The null hypothesis (H0) is that there is no difference in the clinical and radiographic success between the TotalFill® BC RRM™ Fast Set Putty and Produits Dentaires™ (PD™) MTA WHITE when used as a pulp dressing in pulpotomies of primary molars.

As part of root canal treatment, canals should be sealed to prevent further contaminations. There are multiple accepted techniques to fill-obturate canals. In the past, different obturation techniques have been compared. The most current technique used, a single cone with bioceramic sealer, has not been compared. This clinical investigation will compare the postoperative pain of this technique to another common technique used in our clinic. Postoperative pain after one-visit root-canal treatment on teeth with vital pulps: Comparison of three different obturation techniques.

The purpose of this randomized clinical trial was to evaluate the incidence of postoperative pain after retreatment using different techniques. Patients whom need retreatment were included. The presence of postoperative pain was assessed after retreatment cases at 1, 6, 12, 24 and 48 hrs.

Endodontic therapy is to achieve the eviction of the inflamed or infected pulp and fill the canal opening with a hermetic sealing material. The analysis of the literature on intracanal therapeutic shows great variability of the results obtained, the reported success rate is 53 to 95%. This is explained by the difficulty of the surgical procedure, but also by the multiplicity of possible factors of failure, related practitioner, canal anatomy, the operating procedures, the preparation techniques and root canal filling. This success rate is variable depending on the presence or absence of periapical pathology before treatment: more than 85% for teeth treated without initial periapical pathology against only 62% for teeth with pathology before treatment. Furthermore, the literature review revealed two contradictory assumptions about the dominant factor failure in endodontics: the failure of the sealing canal system (bad level shutter) against the failure of the endovascular disinfection. Main hypothesis of the research objectives: The probability of success in a year endodontic treatments carried out according to the recommendations and the operating standards on teeth with periapical pathology is approximately 60%. The primary prognostic factors would be the existence of intracanal obstacles (stop calcification ...) responsible for a sub-obturation of the canal, factors inherent to the tooth (situation ductal anatomy and complexity), the operating techniques used, the practitioner ( skill level), the quality of the restoration.

This study was conducted to evaluate clinical and radiographical outcome of using a standardized platelet-rich plasma (PRP) biomembrane following endodontic surgery and its correlation with the growth factors content in this concentrate.

The aim of this study is to evaluate the quality of obturation and the time efficiency of rotary versus manual instrumentation in roots of deciduous molars clinically where the: Primary objective Is to evaluate the time efficiency Secondary objective Is to evaluate the quality of obturation Clinical and radiographical follow up will be performed for 18 months to investigate the clinical and the radiographic success for the Conventional and Rotary groups.

Aim of the study: To compare Formocresol and Biodentine clinically and radiographically when used for pulpotomy of primary molars Study Design : A randomized control clinical trial (split mouth and double blind) was conducted on 43 (4-6 years-old) children with decayed vital mandibular primary molars which were treated by pulpotomy using both medicaments . All treated teeth were followed for one year (at 3, 6, 9 and 12 months clinically and at 6 and 9 radiographically).

Restoration of endodontically treated teeth requires a means to protect the cusps from the wedging forces of occlusion. When there is extensive loss of tooth structure, cuspal coverage is warranted. Usually this is in the form of indirect restoration. Traditionally, full coverage crowns have been used which would require further removal of sound tooth structure. Recently, adhesive alternatives have been introduced which allow for conservation of tooth structure. Different materials can be used for this purpose. The evidence on the long-term survival of these materials is scarce. This study aims to investigate the short and medium-long term survival rate of these prostheses.

Trial is designed to allow revascularization and tissue engineering in necrotic teeth with peripical lesion in a single visit approach. different disinfection protocols is used to ensure that adequate disinfection of root canals is achieved to allow stem cells to differentiate and proliferate generating pulp like tissue and turning back tooth to live with periapical healing of resorbed bone.

The aim of this clinical study was to compare the radiographic outcome of a root canal treatment with or without use of MTAD after 24 months recall. This in vivo study was a prospective, single-center; single blinded, parallel, and randomized clinical trial. The study protocol was approved by the Ethics Committee of Cukurova University Faculty of Medicine. One hundred patients with a noncontributory medical history presented to the Department of Endodontics of the University of Cukurova Faculty of Dentistry between October 2019 and February 2020 were selected according to inclusion and exclusion criteria. All selected teeth were single-rooted, maxillary and mandibular incisors, canines or premolars that were asymptomatic (no preoperative pain, swelling or acute endodontic or periodontal abscess). All pulps were nonvital and did not respond to cold testing. All patients were aged between 18 and 65 years, had no systemic diseases or allergies tolocal anaesthetic agents, had not previously received any endodontic treatment and had no radiographic evidence of periapical bone loss. Pregnant and breast-feeding women and patients taking analgesic, anti-inflammatory or antibiotic medications during the 7 days prior to the beginning of treatment were also excluded. All patients were informed that they were to be included in a clinical trial and their consent was obtained.The initial periapical radiographs of the patients were taken with the digital imaging system Digora Optime (Soredex, Tuusula, Finland) by long-cone paralleling technique with a film holder (Endo Rh plus; Indusbello, Londrina, PR, Brazil), the vitality of the pulp was evaluated by an electronic vitalometer (Analytic Technology Corp., Redmond, WA, USA) and confirmed by the absence of bleeding from the endodontic access cavity. For both maxillary and mandibular teeth, local infil-tration anaesthesia was achieved using 2 mL articaine hydrochloride with 1:200 000 adrenaline (Maxicaine; VEM Ilac, Istanbul, Turkey). Endodontic access preparations were performed using diamond round burs. After the canals were visible, patency was checked with a K-file (VDW GmbH, Munich, Germany), and a dental dam was placed to isolate the tooth. The working length (WL) was determined with an electronic apex locator (Raypex 6,VDW) and accepted when all 3 green bars were reached. In addition, the canal length was confirmed by a periapical radiograph, and the apex locator was accepted as correct in situations where the two did not match. Root canal instrumentation was performed using the Reciproc Blue (VDW, Munich) #50/0.5 file. During instrumentation of the root canals, irrigation was applied with 10 mL 2.5% NaOCl using side-vented needles (NaviTips, 30 gauge; Ultradent, South Jordan, UT, USA). The final irrigation in Control group was applied with 5 ml of 17% EDTA solution and 5 ml of distilled water. In the MTAD group, final irrigation was done with 5 mL of MTAD and 5 mL of distilled water. Side-vented needles were placed 1 mm shorter than the working length, and 5 ml of solution was given in 2 minutes. The root canals were dried with sterile paper points and were filled with cold lateral condensation technique using AH Plus root canal sealer (Dentsply Maillefer, Cologne, Germany) and gutta percha (President Dental, Duisburg, Germany). Then the cavity entry was restored with composite (Solarex, GC Corparation, Tokyo, Japan) and radiography was taken. Patients were invited to follow-up sessions at 6, 12, 18, and 24 months and were radiographically and clinically assessed. Many patients missed their follow-up appointments due to the covid 19 pandemic. The follow-up radiographs performed by long-cone paralleling technique with a film holder. The pre-treatment and 24-month follow-up radiographs of teeth, were prepared as a Power Point presentation (Microsoft ® Corporation, Redmond, WA) and the change in periapical radiolucency was assessed according to PAI scores of five categories; 1. Normal apical periodontium 2. Small changes in bone structures 3. Change in bone structure with mineral loss 4. Periodontitis with well-defined radiolucent area 5. Severe periodontitis with exacerbating features. Teeth with a PAI≤ 2 score and clinically asymptomatic were considered 'healthy' in the radiographic evaluation, while teeth with a PAI≥ 3 and/or clinically symptomatic were considered 'failure'.
