Abstract
Objectives: The coronally advanced flap (CAF) is a set of techniques that combines surgery with the inclusion of different regenerative materials and biologic factors to achieve both functional attachment apparatus regeneration and root coverage. The tensile strength of granulation tissue is dramatically increased by HA, which also stimulates blood clot formation and causes angiogenesis. The purpose of this study was to see how well coronally advanced flap operations combined with hyaluronic acid treatment worked for miller class I single gingival recession.
Supjects and methods: The two contralateral locations at the split mouth were randomized so that a patient might function as his or her own control. One side was treated with coronally advanced flap with hyaluronic acid application (CAF + HA; test group), whereas the other was treated with coronally advanced flap alone (control group) . Keratinized tissue was assessed for recession depth, probing pocket depth, and clinical attachment level.
Results: CAF/HA sides showed a lower Recession depth than CAF sides. The decrease in probing depth was higher in CAF/HA sides than CAF sides.CAF/HA sides showed a lower clinical attachment loss than CAF sides. The decrease in CAL was higher in CAF/HA sides than CAF sides. The increase in Keratinized tissue was non-significantly higher in CAF/HA sides than CAF sides.
Conclusion: In Miller Class I single gingival recession, combining hyaluronic acid with the CAF treatment increases the likelihood of obtaining root coverage and improving recession reduction.
