Using a surgical microscope to improve gum flap healing

The Effect of Microsurgical Approach to Periodontal Flap Healing: A Randomized Controlled Trial

Not applicable Interventional The University of Texas Health Science Center at San Antonio · NCT07054008

This study will test whether using a digital surgical microscope helps adults needing periodontal flap surgery heal better than using dental loupes.

What this trial studies

This is a randomized, two-arm split-mouth trial comparing a microsurgical approach with a digital microscope to the standard surgical approach using dental loupes. Each participant receives both approaches on different sites, so they serve as their own control. The trial uses standardized vertical releasing incisions and random allocation of which side receives the microscope versus loupes. Post-operative wound healing of the incision sites will be measured and compared between the two approaches.

Who should consider this trial

Good fit: Adults aged 18–89 who require surgical periodontal flap treatment (maxillary or mandibular), are ASA I–II, can provide informed consent, and can attend all study visits are ideal candidates.

Not a fit: People who are pregnant, have poorly controlled diabetes (HbA1c > 7.1), require hard-tissue augmentation, are not eligible for periodontal surgery, or are non-English speaking are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the microsurgical approach could lead to faster or stronger healing of periodontal flap incisions and fewer surgical complications.

How similar studies have performed: Prior studies show dental loupes improve surgical outcomes over no magnification, but evidence that higher-magnification surgical microscopes improve periodontal incision healing is limited.
