Different Treatment Modality in Necrotic Primary Molars

Clinical and Radiographic Evaluation of Triple Antibiotic Paste and Calcium Hydroxide With Iodoform as Intra-canal Medications in Regenerative Treatment of Necrotic Primary Teeth Randomized Clinical Trial

Necrotic primary molars in preschool children will be treated with the regeneration concept to provide a healthy biological environment within the root canal system and regression in clinical signs and symptoms which are the primary outcomes of regeneration treatment.

A convenient sample of preschool children have a necrotic primary second molar randomly allocated to one of the 3 study groups which are: group A (control) treated by the conventional treatment ( pulpectomy followed by stainless steel crown SSC), group B: treated by regeneration using triple antibiotic paste followed by SSC), group 3:(treated by regeneration using calcium hydroxide with iodoform(metapex) followed by SSC.

the 3 groups were evaluated at baseline, 6 months and 12 months for clinical and radiographic success.
