Abstract
Purpose: This study examined the width of keratinized gingiva and attached gingiva after an apically repositioned flap (APF group), APF combined with free gingival grafts (FGG group), and APF combined with collagen wound dressing (Collatape® group), both clinically and histomorphometrically.
Materials and Methods: The right and left maxillary canine areas of eight mongrel dogs were used (16 surgical sites). In the maxilla, the canine areas were used as experimental sites. Three different surgical techniques were performed on the sixteen canine areas(apically repositioned flap; APF group, APF combined with free gingival grafts; FGG group, and APF combined with collagen wound dressing; Collatape® group). After 6 weeks, clinical and histomorphometric evaluation were done.
Results: The FGG group showed more attached gingiva and a more favorable physiological appearance than the other groups. However, there was no significant difference in keratinized gingiva and attached gingiva among the three groups. According to the results of the histomorphometric examination, keratinized gingiva were formed in all groups. The FGG group showed thicker epithelium and connective tissue than the APF group. Collatape® group showed thicker connective tissue than the APF group.
Conclusion: The clinical and histomorphometric results suggested that APF combined with collagen wound dressing promotes more favorable healing of the keratinized and attached gingiva.
