A Comparison of Side Access Mucosal Releasing Incision (SAMRI) and Sulcular Tunnel Access to Treat Gingival Recession.
NCT04179448 · View on ClinicalTrials.gov ↗
Study Summary
This study will compare two incision designs to allow for coronal gingival/mucosal flap advancement and tissue augmentation with acellular dermal matrix (ADM) graft around teeth with gingival recession and a lack of adequate keratinized gingiva. The SAMRI technique described is a novel technique involving a simplified incision and suturing technique and to the investigators' knowledge, this is the first study that seeks to compare this technique to other techniques for differences in clinical outcomes (percentage root coverage, resultant tissue thickness, and width of keratinized tissue) and patient-centered outcomes (post-operative pain, swelling, changes in daily activities, and patient-assessed esthetics) in a controlled study.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04179448
The ClinicalTrials.gov registry entry for NCT04179448 describes a study currently listed as active not recruiting. 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 22 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Alabama at Birmingham, which has 1,315 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 Gingival Recession appearing as the primary indexed condition, and to 2 interventions — of which SAMRI 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: NCT04179448 reports 1 study location spanning 1 distinct geographic area — top geographies include Alabama. 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.
