23 Clinical Trials for Various Conditions
The purpose of this study is to understand the effect that 3 different types of root canal procedures have on bacteria.
The purpose of this study is to develop a protocol for biofilms disinfection with a FDA cleared, clinically approved and commercially available Er,Cr:YSGG laser treatments. This protocol will be testing local single topical application of Lasers within the canal system in patients going through routine endodontic treatment, evaluate its potential as anti-biofilm treatment and compare it to other currently used antibacterial protocols.
The goal of this study is to evaluate non-drug approaches to reducing dental anxiety prior to non-surgical root canal treatment. This will be done by comparing two relaxation methods which will be performed immediately prior to scheduled, clinical non-surgical root canal treatment. Measures of anxiety will be evaluated prior to, and after, the relaxation intervention, as well as after the non-surgical root canal treatment is completed. Participation in the study is completed in a single study visit.
The purpose of this study is to understand and learn better the efficacy of GentleWave and obtain histological evidence of the efficacy of this new technology done in-vivo
The purpose of this study is to to compare root canal therapy success between two root canal filler materials: 1) gutta percha (GP), 2) gutta percha modified with nanodiamonds and amoxicillin (NDGX). Gutta percha is the current standard root canal filler material used during non-surgical root canal therapy (RCT). Gutta percha modified with nanodiamonds and amoxicillin is an investigational root canal filler material, not yet FDA approved for use as described in this study. The safety and usefulness of NDGX is being tested in this study in comparison to the current standard of care, gutta percha (GP).
This study is looking into two different ways to perform a root canal treatment. The study will look at differences and compare the two different treatment options over a 2-year period.More specifically, this study evaluates a small "skinny" root canal shape compared to a larger "broad" root canal shape and if this affects the success of the root canal treatment. Both types of treatment are standard of care and aim to treat the infection inside your tooth. When a tooth is infected with bacteria, we can see a dark area on the radiograph around the roots of the infected tooth. If this dark area becomes smaller or goes away completely after root canal treatment and you do not feel any pain or other symptoms, then we know that the treatment was successful and there is no need for further treatment on this tooth. To measure the size of the dark area around the tooth (i.e. volume) before and after the treatment we will need to take two limited volume three-dimensional radiographs (cone beam computed tomography-CBCT), one prior to treatment and one at two years after the root canal treatment is completed. These radiographs are more accurate in detecting changes in lesion size than the regular periapical radiographs. We will assess the changes in lesion volume for all teeth included in the study and that will help us find differences in success between the two root canal treatment protocols, We are specifically looking for persons that have been diagnosed with a necrotic permanent mandibular molar with an evident radiographic lesion (i.e. dark area around the tooth) that can be retained in the mouth with root canal treatment and permanent restoration. This study place participants in different treatment groups after randomization. Randomization means that you are placed by chance (like flipping a coin) into a treatment group. For this study, there are two treatment groups (protocol) and they are listed below. Protocol 1: Group S: Root canal treatment will be performed in 2-visits using hand files and rotary instruments to a final canal shape of size #25. Protocol 2: Group L: Root canal treatment will be performed in 2-visits using hand files and rotary instruments to a final canal shape of size #35
Non-surgical root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection while preserving the tooth for the patient for mainly cosmetic purposes. RCT is offered as the better cosmetic, cheaper, and less time intensive treatment option for a patient compared to those of dental implantation. Dental implantation is the alternative to RCT, and they are both originally offered at the time of the initial consultation. RCT involves non-surgically removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue, and using a filler material to replace the non-surgically created space where the pulp was removed. Currently, standard of care treatment for RCT utilizes gutta-percha as the root canal filling material. Our research group has previously demonstrated NDGP's improvement in tensile strength compared to those of gutta-percha. This research studies a new type of filler, gutta-percha modified by the addition of nanodiamond material (NDGP). This is an equivalence study of NDGP and standard gutta-percha administration.
A prospective, literature controlled, clinical study evaluating healing rates for the Sonendo GentleWave System in the treatment of 1st and 2nd molars indicated for root canal therapy.
The purpose of this study is to evaluate patients with emergency pain and a sore (infected) tooth to determine if immediate root canal therapy is better at reducing pain, when compared to initial treatment with antibiotic and pain medication followed by root canal therapy. Each participant will be randomly assigned a number, which will determine if they will receive initial endodontic treatment that day or at a later date. Each participant will receive an anesthetic injection, pain medication and a prescription for an antibiotic. They will be asked to keep a diary to record their pain level after the injection and their pain levels and the amount and type of pain medication taken each day for the next 5 days. Participants who did not receive root canal therapy at the initial appointment will receive it after the 5 day postoperative period. The pain levels and medication use will be compared between the treatment and nontreatment groups.
The purpose of this study is to identify pre-operative factors that put patients at greater risk of developing severe tooth pain following root canal therapy, thereby providing evidence that will allow dentists to act preventively to lessen this risk, improve pain control, increase their patients' quality of life, and decrease the number of dental emergency interactions. A parallel goal of this study is to assess the feasibility of recruiting dentists that provide root canal therapy and patients using the DPBRN.
The purpose of this study is to document by survey the occurence of tooth pain present 3 months and 6 months after root canal therapy in the patients recruited for the DPBRN "Peri-operative tooth pain" study. This study will access the feasibility of obtaining 3 month and 6 month follow-up data on the patient enrolled in the DPBRN "Peri-operative tooth pain" study.
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.
The purpose of this investigation is to assess the use of a novel scaffold (an FDA-approved collagen-hydroxyapatite material called Syn-Oss) for regeneration of pulp tissues versus the use of a traditional scaffold (blood clot).
The aim of the present study is to assess with PA x-rays and CBCT scans the volumetric changes in periapical radiolucencies in endodontically treated teeth 1 year after endodontic treatment and evaluate how well the lateral canals are filled after irrigation with the new generation of negative irrigation pressure unit with and without the ultrasonic irrigation.
The purpose of this registry is to gain a real world perspective for the use and outcomes associated with the Sonendo® GentleWave System usage. The registry population includes up to 500 subjects that have been treated with the Sonendo GentleWave System at up to 25 clinical sites in the United States.
A post market, observational study evaluating the treatment of 1st and 2nd molars indicated for root canal therapy and treated with the Sonendo GentleWave System and obturated with CPoint and BC Sealer in at least one canal.
This study aims to evaluate the efficacy of the GentleWave® System compared to conventional methods in reducing postoperative pain in patients with necrotic pulp or requiring endodontic retreatment.
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.
The study will investigate the impact of an additional injection of long-acting anesthetic on pain level, quality of life, and use of pain medication after a nonsurgical endodontic treatment. The long-acting anesthetic will be compared to a mock injection group and a group with no additional anesthetic to determine any differences in effects.
The purpose of this study is to compare the efficacy of GentleWave versus EdgePro irrigation in the disinfection of infected root canals of human permanent teeth with necrotic pulp.
This study will assess the efficacy of two local anesthetics (2% lidocaine 1:100,000 epinephrine and 0.5% bupivicaine 1:200,000 epinephrine) in reducing post-operative pain in patients receiving endodontic treatment.
The purpose of this study is to compare the accuracy of different apex locators. Before root canal therapy, dentists use a device called an electronic apex locator (EAL) to measure the root canal and to locate its opening at the tip of the tooth's root (called the apical foramen). A root canal is the space inside the root of a tooth. If the tissue within the root canal becomes infected, dentists may perform root canal therapy.
This protocol is for a clinical trial evaluating the clinical success of root canal therapy performed on teeth with chronic apical periodontitis of pulpal origin with either large or small apical root canal preparation techniques.
