Human age estimation from tooth cementum and dentin.
BACKGROUND Age estimation is an important factor in the identification of an individual in forensic science. The hard tissues of the human dentition are able to resist decay and degradation, long after other tissues are lost. This resistance has made teeth useful indicators for age calculation. Recent research has indicated that Tooth Cementum Annulations (TCA) may be used more reliably than an...
متن کاملThe hydrolysis of dentin and cementum glycosaminoglycans following fluoride immersion.
The roots of human premolar teeth were analyzed biochemically for total glycosaminoglycan after fluoride treatment and enzymatic digestion. Base levels of dentin and cement~Jm fluoride (780 +_ 105 ppm) and controls showed a statistically significant difference from the fluoride-treated teeth (1250 +__ 120, 1675 +_ 105, 2150 +_ 145 ppm) for the 1-, 8-, and 24-hour periods respectivel.v. The amou...
متن کاملCoronal displacement of cementum: correlation between age and coronal movement of cementum in impacted teeth.
This study was conducted on 48 impacted and 51 erupted maxillary permanent canine teeth extracted from healthy patients aged 13-73 years. Longitudinal buccolingual ground sections were prepared. The distance between the edges of cementum and enamel in each specimen was measured with an eyepiece micrometer. A correlation test was applied between age and the distance between enamel and cementum m...

متن کاملStructure, chemical composition and mechanical properties of human and rat cementum and its interface with root dentin.
This work seeks to establish comparisons of the physical properties of rat and human cementum, root dentin and their interface, including the cementum-dentin junction (CDJ), as a basis for future studies of the entire periodontal complex using rats as animal models. In this study the structure, site-specific chemical composition and mechanical properties of cementum and its interface with root ...
