Immediate autotransplantation of a mandibular premolar with complete roots to a fractured tooth site, using platelet ‑rich fibrin in an orthodontic patient, report of a case
This study reports the treatment results of a16 ‑year‑old female with severe crowding in upper and lower arches and a fractured mandibularpremolar with a poor prognosis. The crowding of the lower left quadrant was relieved by theextraction of the first premolar. This extracted tooth with a complete root was transplanted to theright quadrant with the fractured tooth. Platelet ‑rich fibrin can stimulate and accelerate periodontalhealing. The platelet concentrate of this patient was prepared and applied to the socket wall at thetime of surgery. The acceptable occlusion and the excellent 4 ‑year prognosis of the transp...

Treatment of strip perforation using cold ceramic
Root perforation may occur at any stage of endodontic treatment and is mostly due to iatrogenicinjury and may compromise the outcome of endodontic treatment. Repairing a perforation isdifficult and the prognosis depends on various factors such as time, site and size of perforation, andthe patient ’s overall health status. Hence, choosing the most appropriate material can be criticalfor the dentist. In this case report of a strip ‑perforation repair, an mineral trioxide aggregate‑likematerial (cold ceramic) that has been shown in previous studies to have favorable properties, wassuccessfully used.Key Words: Canal ther...
