Clinical Performance of Four Restorative Materials in Primary Molars

Clinical Evaluation of an Alkasite Restoration Material (Cention N) and Self-cure Composite (Stela; SDI) Compared to Conventional Composite and Resin-modified Glass Ionomer in Primary Molars: A Randomized Clinical Trial

This randomized clinical trial aims to compare the clinical and radiographic performance of four direct restorative materials used for restoring carious primary molars in children. Eligible children aged 4-8 years with posterior primary molars requiring direct restoration will be randomly allocated (1:1:1:1) to receive one of the following materials: an alkasite restorative material (Cention N), a self-cure bulk-fill resin composite (Stela; SDI), a conventional light-cured nanohybrid resin composite (Beautifil II), or a resin-modified glass ionomer cement (Riva Light Cure). Restorations will be evaluated using the Fédération Dentaire Internationale (FDI) World Dental Federation criteria. Postoperative sensitivity will be assessed at 48 hours using a 0-10 visual analogue scale (VAS). Clinical and radiographic follow-up assessments will be conducted at baseline and at scheduled recall visits

Inclusion Criteria:

1. Age 4-8 years old.
2. Primary molars indicated for restorative treatment.
3. No pulp involvement or history of dental pain.
4. Cooperative children (Frankl: +ve or ++ve).

Exclusion Criteria:

1. Pulp exposure after caries removal or clinical signs of irreversible pulpitis/necrosis.
2. Severe developmental enamel defects or insufficient enamel for bonding.
