Evaluation of the pulp response following direct pulp capping with exogenous nitric oxide and Mineral Trioxide Aggregate (MTA) a histologic study

BackgroundRecently, vital pulp therapy is widely used all over the world. It aims to maintain viability and function of injured dental tissue. Direct capping recognized as one most common techniques in this approach.Aim studywe aimed compare histopathological response following direct using two different materials; exogenous nitric oxide (NOC-18) Mineral Trioxide Aggregate (MTA) dogs’ teeth.Methods materialsThe thirty-two premolars canines from four dogs (eight teeth per each dog) was exposed treated with either MTA (four group). The were extracted prepared for histologic evaluation after month three months, respectively. study evaluated formation dentine bridge, degree pulpitis, calcification coronal tissue odontoblasts layer activity. We have ethical approval achieve research scientific committee Faculty Dentistry, Damascus University.ResultsThe results showed that active statue NOC-18 group significantly more than a recall (P: 0.003). No significant difference found between categories bridge 3 months 1.000).ConclusionExogenous maybe has positive impact on calcified efficacy directly capped dog's teeth. Exogenous NO donors might offer alternative current agents Vital Pulp Therapy endodontic.
