ABSTRACT
Background: Several Medicaments Have Been Used In Pulpotomy Procedures Of Primary And Young Permanent Teeth With The Objective To Maintain Pulp Vitality And Promote Healing Of The Pulp Remnants. Aim Of Study The Aim Of This Study Was To Evaluate The Histological Response Of Pulpotomized Dental Pulp In Dogs To Biodentine And Portland Cement.

Materials and Methods: The Study Included 72 Teeth On 3 Apparently Healthy Adult Mongrel Dogs, It Was Classified Into 2 Groups According To The Tested Material. Group 1: Included 36 Teeth Capped By Biodentine, Group 2: Include 36 Teeth Capped By Portland Cement. The Hard Tissue Formation Over 1, 2, 3 Months Periods Were Recorded.

Results: Histopathological Analysis Showed Complete Dentinal Bridge Formation. Layers Of Well-arranged Odontoblast And Odontoblast-like Cells Were Found To Form Tubular Dentin Under The Osteodentin. Statistical Analysis Showed No Significant Differences Between The Biodentine And Portland Cement Experimental Groups During The Observation Period. Although All Specimens Of Both Groups Showed Formation Of Dentine Bridge, The Dentine Bridge Formed By Biodentine Was Of Better Quality Than Portland Cement Conclusion: Within The Limitation Of The Current Study Biodentine Was Superior To Portland Cement In Terms Of Better Quality Of Dentine Bridge.
