Estimation of age by secondary dentin deposition, root translucency, and cementum apposition: A unique modification of Gustafson’s method
نویسندگان
چکیده
Dentin is a calcified tissue of the body, and along with enamel, cementum, and pulp is one of the four major components of teeth. Usually, it is covered by enamel on the crown and cementum on the root and surrounds the entire pulp. By weight, 70% of dentin consists of the mineral hydroxylapatite, 20% is organic material and 10% is water [3]. Secondary dentin may be defined as the dentin formed continuously throughout life after the crown is fully formed [4].

Physiological Changes in Teeth as a Tool to Estimate Age
With increasing age there are many changes in teeth such as attrition, peridontal disease, deposition of secondary dentine, root translucency, cementum apposition, root resorption, color changes, and increase in root roughness. By taking into consideration these secondary changes in teeth with advancing age, various studies were done to estimate the age of an individual. Such research has resul...
متن کاملA comparative study of efficacy of single rooted and double rooted teeth in age estimation using dentin translucency.
BACKGROUND Among various methods of age estimation using dental tissues, measurement of root dentin translucency (RDT) is said to be the most accurate. Numerous studies have estimated age by measuring RDT in single and double rooted teeth and have shown conflicting results. Only few studies have compared efficacy of using single and double rooted teeth for RDT measurement in age estimation. A...
متن کاملHuman 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 کاملA modified Gustafson method of age estimation from teeth.
Modifications to the Gustafson method of age estimation from teeth are described. They are designed to minimise the subjective nature of the scoring technique and to quantify the regressive changes in the enamel, dentine and cementum. Randomly selected teeth from 25 Indians were examined by the Gustafson method and by our own modification. It was shown that our modified method resulted in more ...
متن کاملRoot surface conditioning with bone morphogenetic protein-2 facilitates cementum-like tissue deposition in beagle dogs.
BACKGROUND AND OBJECTIVE Modification of the root surface may play an important role in regenerating the periodontal attachment between the root and periodontal connective tissue. We speculated that bone morphogenetic protein (BMP) application to the root surface constructed a novel attachment by cementum-like hard tissue, although gingival connective tissue proliferated to the root surface. Th...
