Emphasis has shifted from the "doomed" organ concept of an exposed pulp to one of hope and recovery. The era of vital-pulp therapy has been greatly enhanced with the introduction of various pulp capping materials. The aim of this article is to summarize and discuss about the various and newer pulp capping materials used for protection of the dentin-pulp complex.

The present study aims to evaluate and analyze the efficacy of Platelet Rich Plasma (PRP) with hydroxyapatite crystals for maxillary sinus augmentation procedures. A comparative study of 10 patients with a mean average age of 35 years with less than 5 mm of residual alveolar bone was conducted. Six patients underwent Lateral sinus lift procedure with allografts (platelet rich plasma and hydroxyappatite crystals) and four patients underwent the same procedure but with autografts (symphyseal). Follow-up for a period of 3 years was done. The patients were assessed for postoperative pain, sinusitis, oroantral communication, epistaxis, graft rejection, infection and potential loss of bone and teeth. During the 3 years period of follow-up there were no complications recorded. A mean post-operative augmented height of 15 mm was achieved in all the patients. Maxillary sinus lift procedure using a mixture of hydroxyapatite crystals and platelet rich plasma was found to be very effective in increasing the height of residual alveolar bone when compared to the use of autografts alone.

Schwannoma (neurilemmoma) is a benign neoplasm originated from the neural sheath and occurring most frequently in maxillofacial region. Intraosseous schwannomas are rare. The mandible is the most common site of occurrence for these lesions. We report a rare case of Intraosseous neurilemmoma of the mandible, with an emphasis on clinical, radiographic and pathological findings. The tumor, located mainly in the ramus region, presented as a soft tissue mass in the oral cavity, Multilocular, well-defined, and radiolucent lesion on plain radiography. Dilatation of the mandibular canal was identified. Plain radiography partly helped to identify the solid nature of the tumor. A biopsy was necessary to make the final diagnosis because of the relatively nonspecific nature of the lesion. The lesion was surgically removed and no evidence of recurrence was observed after 6 months.
