Bioceramic Putty Versus MTA in Pulpotomized Primary Teeth to be Covered With 3D Printed Resin Crowns Versus Stainless Steel Crown

Effectiveness of Bioceramic Calcium Silicate-based Pulpotomy Medicament on Primary Molars Restored With 3d Printed Resin Crowns (a Randomized Controlled Clinical Trial)

children aged 5 to 7 years with deep carious second primary molars that require vital pulp therapy will be treated using either MTA or bioceramic putty, then will be fully covered using either stainless steel crowns or 3D printed resin crowns.

removal of caries from second primary molars reaching the pulp, pulpotomy will be done by controlling the bleeding after that pulp chamber will be covered with either MTA or endosequence bioceramic putty.

resin modified glass ionomer will be placed, crown preparation will be done to receive full coverage either stainless steel crowns or 3D printed resin crowns
