A revitalization protocol lead to different outcomes in adjacent teeth

Regenerative Endodontic Procedures can be defined as biologically based procedures designed to replace damaged structures including dentin and cells of the pulp – dentin complex. The term revascularization is more commonly employed with regenerative procedures and describes reintroduction of vasculature in the root canal system. This case report describes the treatment of two nonvital immature teeth with infected pulp. Revitalization was attempted in two adjacent teeth by the same operator following similar protocol. In one of the teeth, revitalization was successful with continued root wall thickening, root lengthening and closure of the apex whereas in the adjacent tooth though root lengthening could not be achieved, a definite apical closure with irregular root wall thickening could be obtained.
