Comparison of Palatal Wound Healing in Diabetic and Non-diabetic Patients: Controlled Clinical Trial and in Vitro Study

Not applicable Interventional Universidade Estadual Paulista Júlio de Mesquita Filho · NCT06540690

This study is testing how well wounds in the mouth heal in people with diabetes compared to those without diabetes after surgery to fix gum issues.

What this trial studies

This study aims to compare the healing of open wounds in the palatal mucosa between diabetic and non-diabetic patients. It will evaluate clinical outcomes, patient-centered measures, inflammatory biomarkers, and the composition of the wound microbiome. A total of 50 patients will be divided into two groups: one consisting of diabetic patients and the other of normoglycemic patients, both undergoing surgery for mucogingival defect correction with free gingival grafts. The study will assess various parameters over a three-month period to understand the impact of diabetes on wound healing.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older, both diabetic patients with controlled type 2 diabetes and non-diabetic patients with good oral hygiene.

Not a fit: Patients with uncontrolled diabetes, significant periodontal disease, or other systemic health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into improved wound healing strategies for diabetic patients.

How similar studies have performed: Other studies have shown varying results in wound healing among diabetic and non-diabetic patients, making this approach both relevant and necessary.
