NCT05555043
Introduction: In the US, 15 million root canal treatments (RCTs) are carried out annually. Success rates decrease with conventional chemo-mechanical root canal preparation techniques used on teeth with periapical radiolucencies associated with bacterial presence. New irrigation modalities, such as the GentleWave® System (GWS) and Waterlase iPlus® (WL), have been developed to overcome limitations and improve RCT success rates. Hypotheses: (1) GWS and WL provide superior clinical outcomes compared to conventional RCT using passive ultrasonic activation (PUI). (2) GWS and WL are acceptable treatment modalities for clinicians and patients. Aims: (1) Estimate probability of success of GWS, WL, and conventional RCT with PUI. (2) Evaluate clinician and patient experiences of the different techniques.
NCT06207253
The goal of this randomized clinical trial is to evaluate the capability of the material to exert bacterial reduction of diclofenac sodium versus of that calcium hydroxide paste when these materials are used as intracanal medications in permanent molar teeth with chronic apical periodontitis. The main question\[s\] it aims to answer are: • Will the diclofenac sodium (NSAIDs) possess antimicrobial efficacy to be used effectively as an intracanal medicament similar to that of calcium hydroxide in primary endodontic treatment? Participants will be allocated randomly into three equal groups by using computer generated randomization, according to the type of intracanal medication.
NCT05935306
The objective of this study will be to evaluate if photobiomodulation (FBM) can reduce postoperative pain in patients who will undergo endodontic surgery. For this randomized, controlled and double-blind clinical study, 34 patients without comorbidities who need endodontic surgery in the upper jaw (15 to 25 teeth) will be recruited. They will be randomly divided into an experimental group (n = 17) photobiomodulation (808nm, 100 mW, and 4J/cm2 with 5 points per vestibular). Applications will be made in the immediate postoperative period and 24 hours after surgery. Control group (n = 17) a FBM simulation will be performed in the same way as in the experimental group. In this group, the required analgesia will be administered within the standard with ibuprofen. Both groups will perform the necessary conventional procedures considered the gold standard in the literature. Both the patient and the evaluator will be blinded to the intervention performed. The primary outcome variable of the study will be postoperative pain, which will be assessed using the visual analog scale at all postoperative control visits (baseline, 24 hours and 7 days). As for the secondary outcome variables, the amount of systemic medication received according to the patient's need (will be provided by the investigator).. Radiographic images will be obtained after 1 and 2 months for evaluation of the repair (dimensions of the lesion, radiopacity). These radiographs will be taken digitally with the positioners implemented. Edema, ecchymosis, and evaluation of soft tissues in the anterior portion of the intra and extra-oral maxilla will also be evaluated. In addition, a digital thermometer. These parameters will be evaluated 24 hours and 7 days after the intervention. The X-rays will be taken in the 1st and 3rd month respectively.
NCT06913673
This study aims to compare the postoperative pain and incidence of extrusion of two intracanal medications in the retreatment of single-rooted teeth. The main question it aims to answer is: Does the injection of intra-canal medication into the shaped root canal after complete removal of the old obturating material lead to post-operative pain and paste extrusion to periapical tissues or not?
NCT05984940
The use of bioceramics materials as root canal fillings in endodontics is gaining traction due to their excellent biocompatibility, antibacterial and sealing abilities. They are dispensed in the form of sealers and cements to be used with gutta-percha or mixed with liquids to form a paste. Recently, Ortho MTA (BioMTA®) cement is clinically available as a root filling material, without the need for gutta-percha. The purpose of this randomized controlled clinical trial is to compare clinical outcome between the novel Ortho MTA (BioMTA®) and the conventional gutta-percha with bioceramic sealer, when used as obturating materials in root canal treatment. This research aims to compare the healing outcome of infected teeth treated by root canal treatment and root-filled using MTA cement (Ortho MTA, BioMTA® Seoul Korea) or bioceramic sealer (AH Plus® Bioceramic Sealer (Dentsply). The sealer can be used alone or in combination with gutta-percha obturating cones, injected gutta-percha material or core-carriers master cones. In vitro studies have demonstrated the capability of MTA to generate hydroxyapatite precipitates that penetrate into dentinal tubules.
NCT06386991
In this study researchers plan to conduct, three different irrigation solutions that are responsible for the release of growth factors necessary for the success of regenerative endodontic treatments will be used. These solutions; Ethylene Diamine Tetra Acetic Acid (EDTA), Etidronic Acid and Citric Acid. The aim of this study is to evaluate the effect of different irrigation solutions used in regenerative endodontic treatment of necrotic open apex molar teeth on postoperative pain. Additionally, the healing of these teeth will be monitored for 1 year.
NCT06035185
The goal of this observational study is to define the role of apical shaping and irrigation activation on root canal cleanliness. The main questions it aims to answer are: * does the effectiveness of irrigation activation depends on apical shaping? * can a similar success be achieved by increasing apical shaping without irrigation activation Participants will \[describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items\].
NCT03635515
This is a clinical study that will investigate the occurrence of post-operative discomfort following the use of the Gentlewave System for root canal disinfection and irrigation. Assessment of discomfort level will be via a visualized analog pain scale.
NCT04481945
Successful endodontic treatment depends primarily on the elimination of infecting microorganisms. This is done by chemo-mechanical preparation of root canals, which is not enough and microorganisms might still survive. Thus, from the main requirements of sealers is to have antibacterial properties and adaptability. Those requirements are needed to kill persisting bacteria after obturation and provide effective seal. Therefore, nanosilver and chitosan inserted to BC sealer and so the antibacterial activity will be assessed on E. faecalis using direct contact test after the setting of the sealer, and the results will be reported using percentage reduction of the colony forming units. Besides, adaptability will be assessed using scanning electron microscope.
NCT04527705
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.
NCT04133181
This study is to compare the clinical and radiographic outcomes after guided periapical endodontic surgery versus conventional endodontic surgery.
NCT04109417
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.
NCT03853200
This study was conducted to determine the antibacterial affect of three different solutions used as final irrigant during endodontic therapy. The investigator's objective was to compare the antibacterial affect of relatively new final irrigant QMix with EDTA and Qmix with EDTA+CHX by evaluating the bacteriological status of the root canal before and after use of the final irrigant.
