BACKGROUND: The importance of keratinized tissue is a controversial subject. However, in some situations most clinicians would agree that surgical procedures to increase the amount of keratinized tissue without root coverage are indicated. In this study, 3 surgical procedures were compared in their ability to increase the width of keratinized tissue. They are: the epithelized autogenous masticatory mucosa graft (free gingival graft), autogenous predominately connective tissue graft (connective tissue graft), and acellular dermal matrix.
METHODS: Forty-five patients referred for treatment of areas with inadequate keratinized tissue were randomly assigned into 1 of 3 groups of 15 each. Each group was treated with 1 of the 3 surgical procedures to increase the width of keratinized tissue. The width of keratinized tissue pre- and postsurgery was evaluated.
RESULTS: All 3 groups started with a similar width of keratinized tissue. All of the surgical procedures resulted in a statistically significant increase in the width of keratinized tissue: free gingival graft, 4.1 mm; connective tissue graft, 3.6 mm; and acellular dermal matrix, 4.1 mm.
CONCLUSION: A statistically significant increase in the amount of keratinized tissue was obtained with all 3 surgical procedures evaluated.
