24 Clinical Trials for Various Conditions
The goal of this clinical trial is to compare the effect of CBD candy versus sugar free candy on reducing the number of bacteria causing tooth decay, in adults The main question is to see whether CBD have any effect on reducing the number of Streptococcus mutans, in the oral cavity the main bacteria causing tooth decay. Participants will be randomly placed in a group, and assigned to take either CBD-infused lozenge (if in the experimental group) or a sugar-free candy (if in the control group) once a day for 15 days. A sample of saliva will be collected and analyzed in a lab before and after consumption of the candy to see whether either product could reduce the harmful bacteria in the mouth.
Fluoride is very effective in preventing dental decay (cavities) when applied in the form of a varnish on tooth surfaces. The purpose of this study is to verify if fluoride-releasing primer (OpalSeal) offers more protection against early dental decay (cavity) compared to conventional primer (Transbond XT) during treatment with braces.
This prospective study compares the use of indirect pulp therapy and mineral trioxide aggregate pulpotomy for pulp therapy of the primary molar with dental caries approaching the pulp.
The proposed test is intended to enable dentists to differentiate between cavitated and non-cavitated tooth decay in the areas where teeth are in contact (interproximal surfaces). In these areas, dentists cannot visually inspect for caries, and currently bitewing X-rays (BWs) only correctly detect the presence of enamel decay 15-25% of the time. This low sensitivity can lead to late treatment resulting in unnecessarily large fillings, crowns, pain, root canals, and possible later loss of teeth.
The purpose of this study is to determine whether lesion infiltration is an effective management strategy to arrest early tooth decay.
The purpose of this study is to determine whether a two-week course of disulfiram will reduce the HIV-1 latent reservoir in patients on highly active antiretroviral therapy (HAART).
The HIV integrase inhibitor, raltegravir (RAL), which was recently approved by the FDA, has been shown in several trials to be highly effective. The purpose of this trial is to estimate the viral load decay rate in treatment-naive HIV infected participants receiving RAL and emtricitabine/tenofovir disoproxil fumarate (FTC/TDF).
Study aim is to compare Lava Computer Aided Design / Computer Aided Milling Computer Aided Machining (CAD/CAM)crowns that are veneered (covered) with porcelain that has been milled using CAD/CAM, with similar CAD/CAM Lava crowns that have been veneered with a hand fabricated porcelain covering.
The purpose of this research study is to test the effectiveness of two different crowns/caps on teeth for restoration of primary anterior teeth. The two different materials of crowns are esthetic crowns with retentive grooves and without retentive crowns. These crowns are placed on the teeth to restore function, esthetics and prevent further caries and infection.
The purpose of this research study is to test the effectiveness of two different crowns/caps on teeth for restoration of primary molar teeth. The two different materials of crowns are resin polymer and stainless steel crowns. These crowns are placed on the teeth to restore function and prevent further caries and infection.
This research study is looking at a new bond-promoting substance (a dental adhesive called 3M™ Scotchbond™ Universal Plus Adhesive) used between the tooth and dental restoration (filling). This study will evaluate whether Scotchbond™ Universal Plus Adhesive (SBU+) is as effective at bonding dental fillings as Scotchbond™ Universal Adhesive (SBU) for preparation of posterior Class I and Class II restorations in adult patients. Participants must have at least two (2) back teeth that need a filling either on the chewing surface alone (Class I) and/or on the chewing surface and between your teeth (Class II). One tooth will be restored using SBU+ and the other tooth will be restored using SBU adhesive, both filled using Filtek™ Universal Restorative as the filling material.
This study will compare the post sedation events from three different multi-drug oral sedation regimens in order to help pediatric dentists determine the best course of action for their patients and prepare parents appropriately and caution them about the expected effects. Patients will be evaluated for adverse effects within two time periods at 8 and 24 hours post oral sedation procedure using surveys.
To evaluate a novel technique of bone regeneration and simultaneous implant placement in severely damaged sockets.
This investigation will be a clinical trial to study the performance of a newly developed high strength ceramic material for crowns. The ceramic has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. Two adhesive resin cement techniques will be used to hold the crown to the tooth and they will be evaluated for creating sensitivity to the tooth. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.

This study investigated if computer games can be effective at changing the way children take care of their teeth. We a museum exhibit with 3D virtual reality games called "Attack of the S. Mutans!" Our hypothesis was that children who played the games and visited the exhibit would show improved attitudes about oral health, which would translate into improved brushing and self-care habits. In this randomized controlled study with school children aged 8-12, we compared the outcomes for three groups: Group 1) Visited Attack of the S. Mutans!; Group 2) Experienced a hands-on classroom presentation about virtual reality being used for healthcare; Group 3) Received no-treatment.
Funded by the Ohio Department of Job and Family Services - Medicaid Technical Assistance and Policy Program (MEDTAPP), the "Child Health Excellence Center - a University-Practice-Public Partnership" (CHEC-UPPP) focuses on improving the health of Ohio's children in 3 target areas: 1) prevention of dental decay; 2) detection and management of overweight and obesity; and 3) lead screening. These topics represent critical public health issues for Ohio's children. The study is based on strong evidence that interventions are needed to improve practice in the target areas and that achieving these goals represents fundamental improvements in child health care that would reduce morbidity and costs. The approach for the study involves a trained Practice Facilitator (PF) working with multiple pediatric and family medicine practices to create change tailored to individual practice preferences and methods of operation. Our overall hypothesis is that a university-community consortium, utilizing evidence-based methods (involving education plus a facilitated, practice-tailored approach) will increase the rates of targeted services in primary care practices.
The purpose of this study is to determine if regular rinsing with chlorhexidine is effective as a long-term preventive method for reducing the incidence of tooth loss in low income older adults. The true end-point of the study is tooth loss after five years of regular rinsing with chlorhexidine or a placebo; surrogate endpoints are periodontal disease, root and coronal decay.
This study focuses on assessing dental caries, erosive tooth wear, and fluorosis in primary teeth using a 3D intraoral digital scanner. The investigator will validate findings using three key indices: ICDAS (for caries), BEWE (for erosive wear), and TF (for fluorosis). Teeth will be cleaned and examined visually using dental tools and light. After visual checks, teeth will be scanned with a 3D intraoral scanner. Children aged 3-12 years with fully erupted primary teeth, seeking dental treatment at the Department of Pediatric Dentistry, Indiana University School of Dentistry. The visual examination and digital scanning will be performed just once and during the dental appointment at the clinic of Pediatric Dentistry following the protocols used in the clinical routine. It is expected to complete the visual examination and the digital scanning in 30 minutes.
The goal of this clinical research study is to find out if 1% chlorhexidine gluconate gel will decrease the amount of bacteria that causes tooth decay. Whether the gel is acceptable to patients will also be studied.
This research aims to facilitate the successful implementation of the new Heart and Stroke Foundation of Ontario dysphagia screening model for acute stroke patients. The objectives will be 1) to determine the natural history of dysphagia screening skill decay, and 2) to assess the benefit of independent web-based practice and periodic feedback on screening skill maintenance. We will enrol a convenience sample of nurses who currently work with stroke patients but who have had no prior formal training with dysphagia screening. The study will consist of 2 phases: A) an initial pilot phase followed by B) a prospective randomized controlled study. During Phase A, three new web-based, self-instructed skill refresher courses will be developed to help nurses maintain the skills they will learn in an 8-hour workshop on dysphagia screening. During Phase B, nurses will receive the 8-hour workshop and one-on-one evaluation by a speech-language pathologist (SLP). Following training, competent screeners will be randomized into one of two groups: Group A - Control group with no refresher course or periodic feedback from SLP; Group B - Web-based skill refresher courses only. Nurses will be evaluated at several timepoints throughout Phase B to assess theoretical dysphagia screening knowledge and skills.
The primary purpose of the study is to investigate the safety and efficacy of KP-1461 given every 12 hours for 124 days to HIV+ patients who have failed multiple antiretroviral regimens.
The goal of this proposal is to test the overall hypothesis that subjects with chronic or recurrent low back pain have an abnormal soft tissue response to acupuncture needling, and that this altered response is associated with abnormal perimuscular connective tissue structure and biomechanics. We will also test whether or not altered needling responses in low back pain are generalized, or localized to specific locations as predicted by traditional acupuncture theory. This proposal is part of a series of projects investigating the role of connective tissue in the mechanism of acupuncture and, in addition, constitutes a first step in examining the role of connective tissue in low back pain. Acupuncturists describe qualitatively different needling responses at locations believed to be "involved" in the patient's disease process. Although assessing abnormalities in the needling response is a fundamental aspect of acupuncture therapy, what constitutes a normal vs. abnormal needling response has never been studied quantitatively. Thus the nature of tissue changes underlying these phenomena remains unknown. We have recently developed a new in vivo technique based on ultrasound elastography that allows visualization and quantification of tissue displacement and strain patterns developed in tissues during needle manipulation in humans \[1\] (Appendix A). In this proposal, we will use ultrasound elastography, ultrasound image analysis and biomechanical modeling to perform 1) quantitative measurement of soft tissue behavior during needling and 2) detailed analysis of perimuscular connective tissue structure and biomechanics in human subjects with and without low back pain.
