Comparison of Oral Hygiene & Root Resorption During Orthodontic Treatment
NCT02745626 · View on ClinicalTrials.gov ↗
Study Summary
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 betw

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02745626
The ClinicalTrials.gov registry entry for NCT02745626 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 68 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is UConn Health, which has 176 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Orthodontic Pathological Resorption of External Root appearing as the primary indexed condition, and to 1 intervention — of which Appliance is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02745626 reports 1 study location spanning 1 distinct geographic area — top geographies include Connecticut. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
