Background Endodontic treatment of young permanent teeth with necrotic pulp presents a clinical challenge for the dentist, and conventional endodontic treatment will result in tooth fracture along with a poor prognosis. Regenerative endodontics is a new protocol that has been advanced in the last decades for managing immature permanent teeth. Rare successful management of immature permanent incisors using platelet-rich fibrin is a technique-sensitive procedure. Case presentation A 08 years 04 months old female reported the chief complaint of pain in the upper front tooth region for one week. A blunderbuss canal was identified on radiographic examination, and revascularization using platelet-rich fibrin was planned and adopted. After the treatment, apical closure and root lengthening were noted without complications during subsequent follow-ups. Complete periapical healing with greater than 1.5 cm of dentinal thickness was noted. Conclusion Revascularization can be considered a viable treatment option for immature nonvital permanent teeth; with advancements in regenerative medicine and clinical practices, revascularization therapies could be developed as a novel mode of treatment in non-vital and dental traumatic cases.

Objective:The objective of the study was to evaluate and compare the residual dentin surface after chemo-mechanical caries excavation with Carie-careTM and Brix-3000 by scanning electron microscopy in primary molars. Materials and Methods:Extracted sixty deciduous molars with occlusal caries were collected and randomly assigned into two groups with thirty each. Group 1; samples were treated with Carie-careTM, Group 2; samples were treated with Brix-3000. Following caries excavation, the tooth specimens were subjected to scanning electron microscopic evaluation.Results: Scanning electron microscopic evaluation showed that the two agents were equally effective in removing the infected dentin and smear layer in primary teeth. However, on statistical comparison using Chi square test and Mann Whitney showed no significant differences in two groups. Conclusion:Both the chemo-mechanical caries removal agents were effective in caries removal in primary molars. Hence, Brix-3000 can be effectively used in primary teeth in clinical practice.
