Details and patient eligibility

About

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.

Full description

Management of deep carious lesion may constitute a real challenge for the operator.The basic idea for treating deep caries is to enhance calcific reparative capacity.Calcium hydroxide has been the gold standard as a capping material but there are some drawbacks like solubility,gaps formation and mechanical instability so a need for a capping material such as calcium silicate has shown several advantages.

Sixty participants will be divided in to two groups (n=30) of patient treated by partial caries removal.The first group(A1) will be treated by light activated calcium silicate and the second group(A2) will be treated by light activated calcium hydroxide after partial caries removal of deep occlusal caries then restore by composite restoration.Paralleling technique using film holders and custom made bite blocks will be used to standardize the serial radiographs and to prevent the distortion of the radiographic image.An increase in dentin thickness will be measured through sequential imaging by soft ware named Digora (Digora Optime,Soredex,Helsinki,Finland) will be used for measurements by digitalizing the scanned image.All images will be studied carefully for an increase in dentin thickness keeping the reference point constant from the furcation area.
