Radiographic Assessment of Calcific Bridge Formation by Light Activated Calcium Silicate Versus Calcium Hydroxide for Deep Caries

sixty participants will be divided in to two groups (n=30) of patient treated by partial caries removal according to the capping material (A),where (A1)represents calcium silicate group,(A2)represent calcium hydroxide group.Apply light activated calcium silicate for group (A1) in deep occlusal caries and taking the base line image after restoring the cavity with composite restoration and apply light activated calcium hydroxide for(A2)group in deep occlusal caries and taking the base line image after restoring with composite restoration.Take follow up image after one year to measure the calcific bridge formation for both groups.
