Clinical Investigation of Effectiveness of a Calcium Silicate Cement

The aim of this clinical study is to investigate the clinical performance of a calcium silicate used in the treatment of deep caries lesions. Individuals participating in the research will be selected from patients with at least one deep dentin caries (D3) who apply to the Restorative Dentistry Clinic of Hacettepe University Faculty of Dentistry. The age range will be range 18-45. The teeth to be restored will be evaluated clinically and radiographically. A rubber dam will be used during the treatment. After the removal of enamel, carious tissue at the lateral walls of cavities will be removed to hard dentin using round and single-use round steel burs operating at low speed in all groups. A reasonable amount of soft carious tissue will be left over the pulp. In test (Calcium silicate) and control(calcium hydroxide) groups, after caries removal, respective material will be applied on the pulpal floor. Then, materials will be sealed by resin-modified glass ionomer cement and permanent restoration will be performed. Evaluation will be conducted after 6, 12, and 18 months.

Inclusion Criteria: * The age of the patient should be ranged between 18-45. * The score of the caries lesion should be D3. * Absence of a history of spontaneous pain in the teeth to be included. * Absence of periapical pathology * No displacement or mobility of the teeth. * Caries should not have reached the pulp tissue, and there should be no root fractures. * Restorable by direct restoration and functional Exclusion Criteria: * Poor oral hygiene of the participant. * Parafunctional habits such as teeth clenching or grinding. * Caries extending to the underneath of gingival margin * Severe periodontal pathology * Previous restored teeth * Teeth undergoing orthodontic treatment
