Background: Age may be estimated using tooth eruption sequence and/or calcification stage. Because many factors affect the time of eruption, stage shows higher accuracy than eruption. Demirjian’s and Willems’ methods have been most commonly used for dental age estimation. Both Willems Demirjian use as an indicator. Studies comparing these shown varied results, they performed on different popula...

Vascular calcification, long thought to result from passive degeneration, involves a complex, regulated process of biomineralization resembling osteogenesis. Evidence indicates that proteins controlling bone mineralization are also involved in the regulation of vascular calcification. Artery wall cells grown in culture are induced to become osteogenic by inflammatory and atherogenic stimuli. Fu...

purpose : to report clinical and pathological features of three cases of opacification with hydrophilic acrylic intraocular lenses (iols) case reports : in this interventional case report, we introduce the surgical and laboratory information about three hydrophilic acrylic iols which calcified after implantation for these patients with cataract. these lenses were explanted and analyzed with opt...

This study was undertaken on human and Rhesus monkey enamel using three methods of analysis to gain information concerning the pattern of enamel calcification: (1) microhardness pattern of enamel mineralization; (2) microradiography; and (3) plastic substitution studies. Halves of teeth were selected and tested on a Tukon Microhardness Tester with a Knoop Diamond Indentor. The other half of eac...

COHEN[1] ascribes a statement to TOMES to the effect that the interglobular spaces are caused by an imperfect calcification of dentin. In 1850, CZERMAK[2] of Germany coined the term Interglobularraume and, later on, these interglobular spaces were assumed or interpreted by KOLLIKER[3], MCQUILLEN[4] and KOLLMANN[5] to be that portion of hypocalcified area occured by an imperfect union of calcosp...

Coralline algae are important components in a large variety of ecosystems. Among them, rhodoliths group free-living coralline red that cover extensive coastal areas, from tropical to polar regions. In contrast other ecosystem engineers, limited research efforts preclude our understanding their physiology, underlying mechanisms, drivers and potential differences related species under varying env...

Calcification is a marked pathological component in carotid artery plaque. Studies have suggested that calcification may induce regions of high stress concentrations therefore increasing the potential for rupture. However, the mechanical behaviour of the plaque under the influence of calcification is not fully understood. A method of accurately characterising the calcification coupled with the ...

Calcification in vitro of the hypertrophic epiphyseal cartilage has served as a useful indicator in the study of the “local factors” involved in calcification (12, 13, 25, 29-31, 34, 37, 38, 40, 44, 54). The appearance of new calcification depends on the functioning of the complete system essential for mineralization. The histological appearance of calcification in vitro of the hypertrophic epi...
