Abstract

Abstract The present study evaluates the healing of an experimental standardized full thickness excisional wound in the palate of a sialadenectomized rat model. Experimental rats underwent sialadenectomy of the submandibular and sub‐lingual glands and ligation of the parotid ducts. A full thickness circular wound, 3 mm in diameter, was produced in the palate. Wound diameter was measured clinically and the area of inflammation and area of new connective tissue formation were determined histologically at 3, 7, 14, 21 and 28 days post‐surgery. Wound diameter was similar in both the experimental and the control groups. The area of inflammation, however, was larger (p<0.05) in experimental rats at days 3, 7 and 14. New connective tissue formation was less (p<0.05) in sialadenectomized rats at days 14 and 21. The present results indicate that palatal wound healing is altered and delayed in sialadenectomized rats.
