Polymethyl methacrylate (PMMA), commonly known as bone cement, is widely used in orthopaedic surgery, mainly for prosthesis fixation, stabilizing compressive vertebral fracture or filling defects. Bone cement a potentially new repair material that has been investigated recently dentistry because of its properties like low cytotoxicity, excellent biocompatibility and resistance to moist environm...

this case report describes treatment of a necrotic immature permanent mandibular first molar with pulpal necrosis in 9-year old female with spondyloepiphyseal dysplasia. the coronal half of the root canal was debrided with a file #30 to remove necrotic tissue, and irrigated with chlorhexidine 0.12%. bleeding was evoked to form an intracanal blood clot; the wound was then dressed with calcium hy...

Root perforations may occur due to pathological processes or treatment consequences. Such perforations are severe complications and are associated with dramatically compromised endodontic treatment outcomes, especially when bacterial infection is allowed to establish and if the seal between the endodontic space and periradicular tissue is not provided. A new known material, mineral trioxide agg...

Injury to an immature permanent tooth may result in cessation of dentine deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in premature tooth loss. Postnatal stem cells, which are capable of self-renewal, proliferation and different...

Currently calcium hydroxide is often used as an intra-canal medication during root canal treatment. It has a pH of approximately 12.5, and it has antimicrobial activity, tissue-dissolving ability, inhibits tooth resorption and induces repair by hard tissue formation. It has been promoted for intra-canal placement for various endodontic conditions, including apexification, apexogenesis, after tr...
