This randomized controlled clinical trial aims to compare the 12-month clinical performance of two HEMA-free universal adhesive systems for restoring anterior cervical carious lesions. Participants will be randomly allocated (1:1) to receive restorations using either a two-bottle HEMA-free universal adhesive (G2-Bond Universal) or a one-bottle HEMA-free universal adhesive (BeautiBond Xtreme), both applied in self-etch mode. The primary outcome is restoration retention, while secondary outcomes include marginal adaptation, marginal discoloration, and postoperative sensitivity, evaluated at baseline (24 hours), 6 months, and 12 months using the modified USPHS criteria.
Inclusion Criteria:
. Patients aged from 18 to 55 years.
Exclusion Criteria:
Patients with severe or chronic periodontal disease.
Participants and outcome assessors will be blinded to the allocated adhesive system. The operator cannot be blinded because the two adhesive systems require different clinical application protocols.
Restoration of anterior cervical carious lesions using G2-Bond Universal (GC Corporation) in self-etch mode followed by Beautifil II LS composite resin.
Restoration of anterior cervical carious lesions using BeautiBond Xtreme Universal Adhesive (Shofu) in self-etch mode followed by Beautifil II LS composite resin.
