Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older with Cairo RT1 (Miller Class I-II equivalent) gingival recession and a Class V cervical defect suitable for restoration or no restoration per protocol.
✕Probably not a fit
Patients without matching defect characteristics or those not meeting oral hygiene or periodontal criteria may not benefit.

What this trial studies
This prospective randomized trial enrolled adults with Cairo RT1 gingival recession and a Class V cervical defect. Participants are assigned to receive a glass ionomer cement restoration, a resin composite restoration, or no restoration before undergoing root coverage with a subepithelial connective tissue graft. Standard periodontal therapy precedes the surgery, and follow-up visits assess root coverage, recession depth, clinical attachment, and tissue stability. The goal is to identify which restorative approach yields the best surgical outcome and gum stability.
Why it matters
Potential benefit: If successful, the study could guide clinicians on the best restorative approach to pair with root coverage surgery for improved gum healing and durability.
How similar studies have gone: Previous related work suggests restoration type may influence soft tissue healing, but data in this exact scenario are limited, making this approach relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: Adults aged 18 years or older. Patients presenting with Cairo RT1 (Miller Class I or II equivalent) gingival recession defects requiring root coverage surgery. Presence of a non-carious cervical lesion (NCCL), an existing cervical restoration, or a cervical defect requiring restoration. Cervical lesion depth of ≤1.5 mm. Patients who have completed initial periodontal therapy before enrollment. Good oral hygiene (Plaque Index ≤20% or as determined by the investigator). Indication for root coverage surgery with a subepithelial connective tissue graft. Teeth suitable for restoration with glass ionomer cement, resin composite, or flowable resin composite, or requiring no restoration according to the study protocol. Ability and willingness to provide written informed consent and comply with study visits. Exclusion Criteria: * Age younger than 18 years. Pregnancy or breastfeeding. Poor oral hygiene. Uncontrolled systemic disease or any medical condition contraindicating periodontal surgery. Bleeding disorders or current anticoagulation that contraindicates connective tissue graft harvesting. Known allergy or hypersensitivity to resin composite, flowable resin composite, glass ionomer cement, or any study materials. Patients who have not completed initial periodontal therapy. Cervical lesions deeper than 1.5 mm. Conditions that, in the investigator's opinion, could interfere with wound healing, periodontal surgery, or study outcomes.
