Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Following a thorough introduction of the procedure to the patients, including addressing all inquiries and obtaining informed consent, we will proceed with the restoration of occlusal caries in two teeth for each patient—one on each side. One tooth will be restored using Ivoclar Tetric N-Ceram composite, while the other will be treated with Ivoclar Cention N bioactive fluoride-releasing filling material, the bioactive fluoride-releasing Cention N is provided as a powder and liquid that must be mixed immediately prior to application.
Both restorations will be performed in a single appointment at the Faculty of Dentistry Clinics, Damascus University, by the researcher.
The procedure will encompass the administration of local anesthesia, cavity preparation, and the complete removal of carious tissue, followed by restoration of the tooth under rubber dam isolation. The quality of the procedure and the final restorations will be evaluated by two independent dentists utilizing the modified United States Public Health Service (USPHS) criteria.
Intervention code [1] 331096 0
Treatment: Other
Comparator / control treatment
The occlusal surface caries in the control group will be restored using Ivoclar Vivadent Tetric N-Ceram composite, a light-cured, premixed, non-bioactive filling material.
The clinical performance of these restorations will subsequently be evaluated in the oral environment according to modified United States Public Health Service (USPHS) criteria.
