Root resorption is a common squeal of traumatic injury to the dentition. Its progression can be minimized by early diagnosis and appropriate treatment. This case report presents the diagnosis and management of a case of trauma induced trio of apical root resorption, intraradicular root resorption and infrabony defect in maxillary central incisor. The main aim in treating such cases of resorptio...
Background and purpose: Root therapy will be successful if it is done based on a correct diagnosis and appropriate treatment plan with the knowledge of morphology and tooth anatomy, debridement, disinfection, and obturation of the entire root canal system. This study aimed to investigate the number and morphology of canals in root canals mandibular anterior using cone beam computed tomography (...
Effects of spreader penetration depth on the quality of apical seal Dr. M. Alaeddini* - Dr. M. Parirokh** * - Oral and Maxillofacial pathologist – Dental Research Centre – Tehran University of Medical Sciences. **- Associate professor of Endodontics Dept. – Faculty of Dentistry – Kerman University of Medical Sciences. Background and Aim: A proper root canal filling is accomplished by complete o...
Abstract Background and aim: Maintaining the original geometry of canal is an important parameter in successful root canal treatment. The aim of this original study was evaluation of apical root canal transportation and centering ability of SafeSider and K-Flexofile using cone beam computed tomography. Materials and Methods: Mesiobuccal root canals of maxillary first molars, with 20-40° curvatu...
A time course analysis using (110m)Ag, (24)Na(+), and (36)Cl(-) examined gill silver accumulation and the mechanism by which waterborne silver (4.0 x 10(-8) M; 4.3 microg/l) inhibits Na(+) and Cl(-) uptake in gills of freshwater rainbow trout. Analyses of gill and body fluxes allowed calculation of apical uptake and basolateral export rates for silver, Na(+), and Cl(-). To avoid changes in silv...
The invasion of erythrocytes by Plasmodium merozoites requires specific interactions between host receptors and parasite ligands. Parasite proteins that bind erythrocyte receptors during invasion are localized in apical organelles called micronemes and rhoptries. The regulated secretion of microneme and rhoptry proteins to the merozoite surface to enable receptor binding is a critical step in t...
BACKGROUND Takotsubo cardiomyopathy is an acute heart failure syndrome characterized by myocardial hypocontractility from the mid left ventricle to the apex. It is precipitated by extreme stress and can be triggered by intravenous catecholamine administration, particularly epinephrine. Despite its grave presentation, Takotsubo cardiomyopathy is rapidly reversible, with generally good prognosis....
