Effect of Pulpotomy Using TheraCal Versus MTA on Survival Rate of Cariously-Exposed Vital Permanent Molars

Preoperative records will be taken (photos, conventional periapical radiographs, and impression to construct acrylic stent to help standardization on follow up apical radiographs). Administration of inferior alveolar nerve block then using rubber dam isolation one of the investigators will remove the caries using large round but under copious amount of coolant and if carious exposure occur, part of the pulp chamber will be removed using sharp spoon excavator. Then the pulp status will be assessed if bleeding is controlled with direct irrigation with distilled water for 2 minutes then next step will be taken but if not continue excavation of the pulp till bleeding is controlled. if bleeding is not controlled after performing complete pulpotomy, tooth will be excluded from the study Then direct application of capping materials (TheraCal or MTA) according to manufacturer instructions, then Riva self-cure glass-ionomer base and composite resin final restoration. One of the investigators will take immediate standardized postoperative periapical radiographs. Follow-up will be for 12 months. Pre-calibrated blinded dentists will assess out comes separately.

Inclusion criteria

• Restorable permanent molars with deep caries and pain could be relieved with analgesics

Exclusion criteria

• criteria of exclusion of teeth were:

• pathological mobility, swelling or tenderness to percussion/palpation;
• pathology is shown in the pre-operative radiographic as resorption periradicular or furcation radiolucency, or a widened periodontal ligament space;
• at the operative procedure, hemorrhage control is unachievable
