Preservation therapy for vertically fractured teeth with periodontal tissue regeneration using FGF‐2

Clinical Advances in Periodontics, EarlyView.
Abstract Background Vertically fractured teeth often have a poor prognosis, and extraction is considered the most predictable treatment. Conventional management has consisted of preservation therapy involving extraction, bonding, root restoration, and replantation of fractured teeth.

Effectiveness of a rock phosphate solubilizing fungus to increase soil solution phosphate impaired by the soil phosphate sorption capacity

Revista Facultad Nacional de Agronomía Medellín, 2015
Available phosphate (P) deficiency in tropical soils has been recognized as a major factor that limits soil quality and plant performance. To overcome this, it is necessary to add high amounts of soluble P-fertilizers; however, this is inefficient and ...

Amorphous calcium phosphates: synthesis, properties and uses in biomaterials [PDF]

, 2010
This review paper on amorphous calcium phosphates (ACPs) provides an update on several aspects of these compounds which have led to many studies and some controversy since the 1970s, particularly because of the lack of irrefutable proof of the occurrence

Perigraftitis treatment and histology: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Currently, the two diagnoses of inflammatory peri‐implant diseases are peri‐implant mucositis and peri‐implantitis. The etiology of peri‐implant mucositis and peri‐implantitis is bacterial colonization of the implant. Thus, removal of the implant should eliminate the infection and allow the inflammation to resolve. However, at least

Perigraftitis, an independent biologic complication associated with implants placed in grafted bone

Clinical Advances in Periodontics, EarlyView.
Abstract Background Perigraftitis is a recently introduced concept describing biologic complications specifically associated with implants placed in grafted bone. It is characterized by inflammation resulting from bacterial colonization of grafted bone and/or residual graft particulates.

Age and origin of fluorapatite-rich dyke from Baranec Mt. (Tatra Mts., Western Carpathians): a key to understanding of the post-orogenic processes and element mobility

Geologica Carpathica, 2016
On the southeastern slope of the Baranec Mount in the Western Tatra Mountains (Slovakia) an apatite-rich pegmatite-like segregation was found in the subvertical fault zone cutting metapelitic rocks.
