Pre-operative ultrasound enables visualization of mandibular arterial branches relevant to flap design in mucogingival surgery. This study documents the pre-and post operative course of these arteries in four CAF procedures using a CE-marked ulstrasound device within its intended purpose.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Age ≥ 18 years.
. Presence of at least one mandibular gingival recession defect (RT1 or RT2) at an anterior, canine, or premolar tooth with an indication for treatment using a coronally advanced flap (CAF).
. Good oral hygiene: full-mouth plaque score (FMPS) ≤ 20% and full-mouth bleeding score (FMBS) ≤ 20%.
. Periodontal stability: no active or untreated periodontitis; probing depths ≤ 4 mm at the study site.
. Ability to undergo pre-operative and post-operative ultrasound imaging and clinical documentation.
. No contraindication to local anaesthesia or minor periodontal surgery.
. Ability and willingness to comply with all scheduled follow-up visits (days 7, 14, 30 and 4 months).
. Provision of written informed consent prior to any study-related procedures.
Exclusion criteria
. Systemic contraindications to minor oral surgery (ASA ≥ III, uncontrolled diabetes mellitus \[HbA1c \> 7.5%\], immunosuppressive therapy, bleeding disorders, or coagulation abnormalities).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Current antithrombotic therapy that cannot be safely managed peri-operatively according to the treating clinician.
. Smoking more than 10 cigarettes per day or equivalent vaping within the previous 6 months.
. Previous mucogingival surgery, traumatic scarring, or soft-tissue grafting in the mandibular anterior or premolar region that could interfere with vascular assessment.
. Active oral infection or acute gingival inflammation at or near the study site.
. Untreated caries, endodontic pathology, or restorative defects at the involved tooth.
. Pregnancy or lactation.
. Known allergy or hypersensitivity to ultrasound gel or (if applied) indocyanine green (ICG) or iodine.
