Pulp and Periodontal Regeneration of an Avulsed Permanent Mature Incisor Using Platelet-rich Plasma after Delayed Replantation: A 12-month Clinical Case Study.

Numerous publications have reported revascularization of necrotic immature permanent teeth, but the regenerative potential of pulp in mature teeth has rarely been considered. Platelet-rich plasma (PRP) meets many requirements of a scaffold for regenerative endodontics. To the best of our knowledge, no clinical study has evaluated PRP for endodontic regeneration in a mature avulsed tooth.

Comparative evaluation of bactericidal potential of four root canal filling materials against microflora of infected non-vital primary teeth.

Background And Objectives: Since complete debridement of the root canals of the primary teeth is not practically possible due to the highly variable root canal anatomy, success of the endodontic therapy depends partly on the use ofantibacterial irrigating agents and root canal filling materials. Recent literature indicates that anaerobes comprise a majority of the bacteria in necrotic root canals ofprimary teeth. The study determined the antibacterial effectiveness of four root canal filling materials namely Calcium hydroxide, Zinc oxide eugenol, Vitapex and Metapex against microbial specimens obtained directly from necrotic root canals of primary teeth.
