Comparative Evaluation of an Alkasite-based Restorative Material and Two Different Resin Composites

Comparative Evaluation of an Alkasite-based Restorative Material and Two Different Resin Composites in Non-carious Cervical Lesions

The clinical performance of an an alkasite-based restorative material and two different resin composites will be evaluated and compared in non-carious cervical lesions. After recruiting participants with at least three non-carious cervical lesions, all restorations will be placed by a single clinician. Lesions will be divided in three groups: an alkasite-based restorative material (Cention N, Ivoclar Vivadent, Schaan, Liechtenstein (CN)), hybrid resin composite (Gradia Direct Anterior, GC, Tokyo, Japan (GD)) and a highly filled flowable resin composite ((G-aenial Universal Flo, GC, Tokyo, Japan (GF)). All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using FDI criteria. Descriptive statistics will be performed using chi-square tests.

Inclusion Criteria:

• Age range will be 18 to 65.
• They will be required to have at least three NCCLs needed restoration in different teeth.
• All the NCCLs selected will be in similar sizes.

Exclusion Criteria:

• Patients with severe periodontal disease
• Patients with rampant, uncontrolled caries
• Patients with xerostomia
• Patients with serious medical problems preventing them from attending review visits
• Patients with poor gingival health
• Patients with heavy bruxism
• Patients with removable partial dentures
• Patients undergoing bleaching treatment or orthodontic treatment
