31 Clinical Trials for Various Conditions
Pressure Pain Threshold (PPT) is defined as the minimum force applied to an area that is perceived as pain. PPT is considered an objective measurement tool to assess pain levels. Studies have assessed the difference in pain levels between clear aligners and fixed appliances using subjective pain scales. No study has utilized PPT to evaluate the difference in pain between aligners and fixed braces at different time points. This study will aim to compare the self- reported and experimental pain perception between the clear aligner and fixed appliance therapies during the phase of crown alignment and to assess how long pain is perceived in the following five days from the adjustment of the appliance.
Comparison of orthodontic patients treated with aligners and traditional (clear braces)
During Orthodontic tooth movement, teeth are moved through alveolar bone under applied forces. The applied mechanical loading force must be transferred to the alveolar bone via periodontal ligament (PDL). This process of mechanotransduction stimulates bone remodeling during which osteoblasts produce bone on the tension side and osteoclasts resorb bone on the compression side of the PDL. Complex interactions between osteoblasts and osteoclasts involve numerous biologic molecules including cytokines and growth factors. During the tooth movement, the expression of cytokines such as interleukin (IL)-1β, IL-6, IL-8, prostaglandin E2, RANKL and MMP1 in PDL will be up-regulated. The sequence of events from the mechanotransduction commanding the tightly controlled accomplishment of osteogenesis attention sides and osteoclastogenesis at compressive sides is not completely understood. The gingival crevicular fluid (GCF) is a transudate of interstitial tissues that is produced by an osmotic gradient and it is released into the crevicular crevices at a flow rate of about 3 ul/h. Orthodontic treatment is triggered by an inflammatory process and it has been hypothesized that the quantification of specific biomarkers within the GCF can be determined using Periotron. However contrasting results have been reported in the literature, which studies showing both increased or unchanged GCF volumes incident to orthodontic treatment. Given that the orthodontic treatment is triggered by a set of inflammatory cytokines that are released into the crevicular fluid during the mechanical loading, and its homeostasis is dependent on mechanical stimulation. An understanding of the biological response of crevicular fluid to mechanical loading could further advance the knowledge of orthodontic treatment. In this study, the investigators will investigate the biological response of gingival crevicular fluid before and after the initial wire placement of orthodontic treatment to determine the differentially expressed genes and proteins related to mechanotransduction.
This study investigates how often cavities develop on the permanent teeth of patients with braces (orthodontic treatment). The hypothesis is that there is no difference in the number of cavities on the permanent teeth of patients with braces compared to similar patients without braces.
This study is designed to determine if the preemptive use of a combination of acetaminophen and ibuprofen is more effective in reducing pain following orthodontic tooth movement when compared to the use of acetaminophen and ibuprofen alone.
The study design of this research project involves orthodontic patients registered at the Harvard School of Dental Medicine who are deemed eligible to undergo orthodontic treatment and who have been provided with sufficient information to make informed consent to join the sleep study. These patients will be provided with the Medibyte sleep monitor and instructed on the proper manner in which it should be set up and worn for the one night study period. This process will be carried out twice throughout the course of the study, once before any orthodontic appliance has been cemented and once after the required amount of tooth movement has been attained with the orthodontic appliance still in place. The de-identified data from the Medibyte monitor will be downloaded using the Braebon software and analyzed.
Orthodontic treatment has been traditionally carried out with fixed appliances involving the use of stainless steel brackets and archwires. The challenge has been to move teeth and their roots effectively while minimizing iatrogenic damage such as root resorption and gingival inflammation. In recent years, with the development of new appliances and brackets such as self-ligating brackets and clear aligners there have been reports of improved periodontal status, less iatrogenic root damage and improved hygiene during treatment. Although these treatment modalities have been rapidly accepted in clinical practice, both clinical and basic science research data regarding their overall biological compatibility to support higher levels of evidence based dentistry (e.g, randomized clinical trials) is lacking. In other words, their advantages and disadvantages in this regard have not yet been scientifically evaluated. Such quantification will provide invaluable information for improvements in these treatment modalities. A randomized controlled clinical trial will be conducted with strict inclusion and exclusion criteria to test the following hypothesis (H) up to 18 months into treatment: H-1: There is no difference in the amount of root resorption caused by the three different appliances. H-2: Gingival health is not affected by the 'type of appliance' being used to correct the malocclusion. H-3: There is no difference in the amount of bacterial count and the type of appliance being used for orthodontic treatment. The hypothesis will be tested with the following specific aims (SA): SA-1: To investigate the amount of orthodontically induced inflammatory root resorption generated by treatment. SA-2: To evaluate the periodontal health of the patients with the different appliance systems. SA-3: To determine the changes in Streptococcus mutans and total bacterial counts contained in the plaque of orthodontic patients. SA-4: To ascertain whether there is an association between the microbial count and the type of appliance being used for orthodontic treatment
The aim of this study is to determine the effect of OrthoPulse™, an intra-oral LED (Light Emitting Diode) photobiomodulation device, on orthodontic treatment time. This is a double-blinded RCT with half the patients receiving treatment from a sham non-functional device, serving as controls, and the other half receiving light therapy treatment from a functional OrthoPulse™. Orthodontic treatment time for the sham-control patients are compared to that of the OrthoPulse™ patients.
The purpose of this research study is to assess the clinical effectiveness of the procedure of a minimally invasive alveolar microperforation procedure to achieve accelerated tooth movement in patients undergoing orthodontic treatment. "Accelerated tooth movement" means that using the PROPEL™ device may help complete your treatment with braces on one side of your mouth sooner than would be expected if the device were not to be used.
The purpose of this study is to learn more about the management of white spot lesions that occur after orthodontic treatment. White spot lesions generally improve slightly with time. To date, there is no proven method to help white spot lesions improve faster. Two treatments, called MI Paste Plus and fluoride varnish, have shown some potential benefits in a laboratory setting but have not undergone testing in a clinical setting. Approximately 240 subjects are to be enrolled in this study. The study will take place in approximately 30 dental and orthodontic offices across Idaho, Montana, Oregon, Utah, and Washington as part of Northwest PRECEDENT, a five-state research network that was created to study the practical issues facing dentists/orthodontists and their patients, and to provide information that will improve the quality of oral health care as a whole. Researchers at the University of Washington and Oregon Health \& Science University share management and oversight of the network and research projects.
The purpose of this study is to evaluate the efficacy of the Aerodentis System for orthodontic tooth movement in an open label, two-arms, non-inferiority clinical study. This open-label, two-arm study will follow 45 patients for up to fifteen months. Thirty participants will wear the Aerodentis device, and fifteen participants will wear Invisalign, a commonly used clear appliance. Patients will be assigned to participate in the treatment group using the Aerodentis device at home for 10 hours daily or in the control group using clear correctors for the duration of up to 15 months. Outcome assessments will be performed every 4 weeks. Assessments will include tooth movement and quality of life assessments.
This description observational research is comparative in design, that is comparing existing standard clinical dental images, not obtained in this study, to test (i.e., ddMRI) images. The standard clinical dental images consist of radiographs, such as bitewings, periapical, panoramic, cone-beam CT, and medical CT, as well medical MRIs of the temporomandibular joints (TMJ).The conceptualization of research questions, study designing, and interpretation of imaging data has and will involve content expertise in all ddMRI research.
The purpose of the study is to determine if Clinpro™ 5000, Clinpro™ Tooth Crème, or MI-Paste Plus has an effect on the formation and resolution of white spot lesions for patients undergoing orthodontic treatment. This study will include 90 patients in the UAB Orthodontic Clinic.
The purpose of this study is to quantitatively investigate the radiographic changes of alveolar bone, and gingival tissue changes of the mandibular anterior teeth in experimental group A receiving SFOT using freeze-dried allograft with a collagen membrane, experimental group B receiving SFOT using particulate xenograft covered by a collagen membrane and control group receiving only orthodontics therapy.
The goal of this clinical trial is to learn if topical application on the all surface of 10% Povidone Iodine (Povi-One) in healthy participants in transitional or permanent dentition (10-17 y) prevents new white spot lesions in the maxillary anterior teeth at 1 year of follow-up. Researchers will compare Povi-One to a placebo to see if Povi-One works to prevent new white spot lesions. It will also learn about the safety of topical 10% Povidone Iodine. The main questions it aims to answer are: 1. Does Povi-One prevent the development of any white spot lesion on the surface of maxillary anterior teeth? 2. Does Povi-One lower the probability of any International Caries Detection and Assessment System (ICDAS) score greater than 0 and mean modified Löe-Silness Gingival Index (GI) in the intervention group? Researchers will 1. Score GI without cleaning participants teeth, then score ICDAS of maxillary and mandibular incisors after participants brush and floss their teeth and take a photograph of maxillary 6 anterior teeth 2. Apply Povi-one (or control) at the consultation appointment before placing fixed orthodontic appliances and 3, 6, and 9 months after appliance placement Researchers will 1. Recall using Zoom 24-48 hours after the first application of Povi-One and examine the participant's mouth for oral lesions using a structured paper checklist 2. Interview the caregiver to complete a paper questionnaire on adverse effects Researchers will 1. Score GI, and then score ICDAS of maxillary and mandibular incisors in 6, 12 months after appliance placement 2. Evaluate the development of white spot lesions on maxillary central and lateral incisors in 6, and 12 months after appliance placement
This study aims to investigate the impact of a bromelain pre-rinse adjunct on oral plaque removal in orthodontic subjects. The study's null hypothesis states that there is no statistically significant difference in visual plaque scores among orthodontic subjects with or without proteolytic enzyme rinse aid.
The aim of this study is to determine efficacy of OrthoPulse photobiomodulation on the rate of tooth movement during alignment for Subjects receiving fixed appliance orthodontic treatment.
The aim of the study is to determine if, and to what degree photobiomodulation treatment with OrthoPulse has an effect on the rate of tooth movement during alignment for patients receiving Invisalign orthodontic aligner treatment.
The AcceleDent® device has been introduced to the specialty of orthodontics in order to reduce treatment time. The theory behind AcceleDent® is that high frequency vibratory forces (30Hz) delivered to the teeth will stimulate the bone remodeling that is necessary for tooth movement to occur more quickly. Additionally, one claim of the AcceleDent® product is that it may reduce pain and discomfort during orthodontic treatment. This study will be a parallel group, triple-blind randomized clinical trial comparing two groups of subjects with 12 participants in each group. Subjects will be randomized to receive one of two vibrational units, which will differ in frequency and/or amplitude of vibration. The subjects will be asked to change their aligners every week instead of every 2 weeks, which is common with Invisalign.
To demonstrate that growing teenagers which present up to full cusp Class II malocclusions can be treated using the Invisalign System.
The aim of this study is to determine the effect of OrthoPulse™, an intra-oral LED (Light Emitting Diode) photobiomodulation device, on the rate of anterior orthodontic alignment.
The aim of this study is to determine if extraoral OrthoPulse®, which emits extraoral LED (Light Emitting Diode) photobiomodulation (PBM), reduces the time it takes to complete orthodontic alignment.
This open label study is designed to evaluate the ability of OrthoPulse™ to safely and effectively increase the rate of orthodontic tooth movement with fixed appliances.
Technological advances have made computer aided orthodontic treatment planning possible. 3D dental scanners and software make it possible to design and approve the outcome before treatment begins. Manufacturers have provided different customized appliance systems that would help practitioners achieve those computer-designed outcomes. The purpose of this study is to determine the accuracy of computer-guided indirect bonding of orthodontic brackets at achieving the predicted alignment and comparing that to the accuracy of conventional orthodontic bracket placement at achieving a predetermined goal. The results of this study will help orthodontists and patients know if there is an advantage to using custom appliances. The study will be a prospective clinical study and will include a total of 60 arches from 30 patients enrolled at the Harvard School of Dental Medicine. 15 patients will be assigned to each of the two study groups (Motion View or control). Both groups will have a 3D intra-oral scan to measure the initial discrepancy and determine the computer-simulated design that the orthodontist believes is the optimized outcome. At the end of each patient's participation, a 3D intraoral scan will be taken and used to assess intra-arch leveling and alignment using ABO's objective grading system's criteria for alignment, marginal ridges and buccolingual inclination. Each arch will then be superimposed on the predicted outcome to determine how accurate each system was at achieving the planned movements in all 3 dimensions. We hypothesize that the accuracy of computer-guided indirect bonding (Motion View) at achieving the predicted outcomes will differ in comparison to the accuracy of conventional orthodontic bracket placement at achieving a predetermined goal.
The purpose of this study is to examine the amount of tooth movement achieved over time between subjects undergoing aligner treatment using a pulsation device known as AcceleDent® Aura with those not using the device.
The investigators are evaluating the effectiveness of custom-made 3D-printed ceramic (tooth-colored) brackets (braces) compared to conventional tooth-colored brackets (braces). Participants will be expected to come in for regularly scheduled appointments. They will be treated with tooth-colored braces and will need to come in every 4-6 weeks and will be randomly assigned to one of three groups. "Randomly" means by chance, like a coin toss. Neither participants nor the researchers may choose group assignments. Group 1 patients will have tooth-colored braces placed directly on each tooth by the clinician. Group 2 patients will have the braces placed on the teeth by using trays to fit them on. Group 3 patients will have customized 3D printed tooth-colored braces placed on their teeth, using trays to fit them on. If a participant is selected to be part of group 3, it may take up to two additional weeks for these 3D brackets to be printed and shipped and so this might delay treatment onset. Information on gender, age, and medical history of participants will also be obtained from the electronic health record.
The primary goal of the study is to determine if there is a difference in pain levels following the use of low level laser therapy versus placebo and control after placement of elastomeric orthodontic separators in pediatric patients. To test this, the investigators will assess the patient's pain levels immediately following separator placement and 24 hours post-operatively but having patients rate their pain on a 10 cm Visual Analog Scale (VAS). Patients will be randomly assigned to one of three groups: treatment, placebo, and control. The aim of this study is to establish whether or not low level laser therapy can be used to reduce pain in pediatric patients following separator placement.
Currently, orthodontic treatment typically lasts approximately 2 years. There are a number of advantages for reducing the duration of treatment, including reducing the potential risk of caries, root resorption and for minimizing patient "burn out" from prolonged treatment. While some evidence does exist that vibration may accelerate the speed of tooth movement, the biological mechanism is still unknown. Identification of specific factors involved in tooth movement that are further stimulated by vibration would help to understand the mechanisms involved as well as discover possible biologic targets which could be utilized or modified to maximize the benefits of vibration treatment. The purpose of this study is to identify novel biological factors that are expressed in patients undergoing orthodontic tooth movement in conjunction with vibration appliance therapy.
Study will look at ability of fluoride varnish to remineralize white spot enamel lesions that can occur around the edge of fixed orthodontic brackets.
The goal of this clinical trial is to determine whether an intraoral Transcutaneous Electrical Nerve Stimulation (TENS) device can reduce pain during orthodontic alignment and leveling in adolescents and adults. The study aims to compare the effectiveness of the TENS device in reducing pain on one side of the mouth, where the device is used, to the other side, where a non-functioning (placebo) device is applied. The primary questions this study aims to answer are: Does the TENS device effectively reduce pain during orthodontic treatment compared to the placebo? How do patients pain levels differ between the treated and untreated sides of the mouth? Participants will: Have an orthodontic appliance placed on their teeth. Experience the TENS device being applied to one side of their mouth for 2.5 minutes immediately after the appliance placement (brackets and wires). Report their pain levels at various intervals after the procedure (immediately, 2 hours, 6 hours, 12 hours, 24 hours, 48 hours, and 72 hours). This study includes up to 150 participants who are undergoing routine orthodontic treatment. The findings will help researchers understand whether the TENS device can effectively reduce discomfort during orthodontic procedures, potentially leading to better patient care and comfort.
