Conditions
Summary
This prospective randomized controlled clinical trial aims to evaluate the influence of different restorative materials placed in Class V cervical lesions on the clinical outcomes of root coverage surgery using a subepithelial connective tissue graft. Patients with Cairo RT1 (Miller Class I-II equivalent) gingival recession associated with non-carious cervical lesions or existing cervical restorations will receive one of the restorative approaches according to the study protocol. Clinical parameters, including the percentage of root coverage and soft tissue stability, will be evaluated during follow-up to determine which restorative approach provides the most favorable clinical outcome.
Eligibility
Inclusion Criteria5
- 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 Criteria4
- 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.

Interventions
No restorative material will be placed in the Class V cervical lesion before root coverage surgery. Participants will undergo root coverage surgery using a coronally advanced flap with a subepithelial connective tissue graft according to the study protocol.
A conventional glass ionomer cement was used to restore the Class V cervical lesion before root coverage surgery with a subepithelial connective tissue graft.
A resin composite material was used to restore the Class V cervical lesion before root coverage surgery with a subepithelial connective tissue graft.
