evaluation of patient morbidity and root coverage outcomes of vista versus caf in treating gingival recession

Conditions: Esthetic Zone

Summary: to evaluate and compare vestibular incision subperiosteal tunnel access (vista) technique,with connective tissue graft; versus coronally advanced flap (caf) technique;with connective tissue graft, in treating gingival recession in esthetic zone. patients and methods: thirty patients, with miller class i or class ii gingival recession, were included in the current study, with age range from 18 to 55 years. defects were treated using either vista combined with connective tissue graft technique, or caf combined with connective tissue technique. post-operative discomfort was evaluated using the visual analog scale (vas) to assess patient morbidity. at baseline, 3, 6 and 9 months, clinical parameters were assessed; probing depth (pd), clinical attachment level (cal), gingival recession height (gh), keratinized tissue height (kth), while complete and mean root coverage (crc, mrc) were recorded after nine months. results: the present study revealed that vista showed higher significant difference in pain.vista also showed a more reduction in pd, cal, gh as well as kth than that of caf with no significant difference between either of the groups.
