Primary outcomes were the change in the width of the zone of keratinized tissue and the amount of root coverage achieved 3\u00a0months postoperatively at the recipient site. Secondary outcomes included change in the thickness of keratinized tissue at 3\u00a0months and patient\u2010reported outcomes, such as pain, bleeding, and swelling at both the recipient and donor sites at 1\u00a0week, 2\u00a0weeks, 1\u00a0month, and 3\u00a0months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>No significant differences were found between the two groups for any of the primary or secondary outcomes.
