Orthognathic Speech Pathology: Phonetic Contrasts of Patients With Dental Discrepancies Pre- and Post-Treatment Analyses
NCT04117360 · View on ClinicalTrials.gov ↗
Study Summary
The investigators are studying how speech is effected by jaw and tooth position in jaw surgery patients. Eighty percent of our jaw surgery patients have speech pathologies, compared to five percent of the general population, but speech pathologists do not understand why. The investigators hypothesize that open bites and underbites prevent most patients from being able to pronounce words normally and surgical correction will lead to improvement in speech. Patients will be audio recorded speaking and patients' tongue gestures ultrasound recorded before and after their jaw surgeries to observe what changes occur in their speech and tongue movements.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04117360
The ClinicalTrials.gov registry entry for NCT04117360 describes a study currently listed as recruiting. It is categorized as an unspecified phase, 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 180 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of North Carolina, Chapel Hill, which has 725 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 10 conditions, with Speech Sound Disorder appearing as the primary indexed condition, and to 1 intervention — of which Orthognathic surgery and Orthodontics 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: NCT04117360 reports 1 study location spanning 1 distinct geographic area — top geographies include North Carolina. 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.
