“…The estimation of the individual age of an unknown corpse is a relatively frequent problem in forensic medicine [11] while determination of fetal age can be of significance in illegal abortions. The most reliable methods are measurements of fetal body length and body weight but these parameters are only useful in the examination of intact fetuses.…”

A total of 53 normal fetuses with a gestational age ranging from 15 up to 39 weeks was investigated and the radial alveolar count (RAC) was estimated as a parameter for lung maturation. Values lower than 2.0 could only be found in lungs of fetuses aged less than 18 weeks. Between 18 and 25 weeks of gestation, relatively constant levels of RAC were observed but with considerable interindividual variation. In fetuses with a gestational age of more than 25 and especially 30 weeks, a slight or rapid increase in RAC occurred respectively. Values lower than 3.0 were found up to a fetal age of less than 30 weeks and a RAC of more than 4.0 was only found in lungs of fetuses aged more than 30 weeks. Values exceeding 6.0 occurred only in fetuses at near full-term birth. Since the estimation of RAC overcomes the effects of varying degrees of alveolar collapse, such an analysis also seems to be useful for the determination for fetal age in cases of advanced putrefaction.

“…With this method, age determination is not suitable with extensive crown destruction in postmortem examination [110] rather than the extraction of the teeth. Ritz et al [110] suggested another less invasive way of racemization estimation by dentinal biopsy specimens taken from molars in living subjects. The extension of aspartic acid racemization is higher in deep layers, so biopsy layer had a noteworthy influence.…”

Post Mortem Examination and Autopsy - Current Issues From Death to Laboratory Analysis

Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. Visual, radiographic, chemical and histological techniques can be used for dental age estimation. Visual method is based on the sequence of eruption of the teeth and morphological changes that are caused due to function such as attrition, changes in color that are indicators of aging. Radiographs of the dentition can be used to determine the stage of dental development of the teeth from initial mineralization of a tooth, crown formation to root apex maturation. Histological methods require the preparation of the tissues for detailed microscopic examination. The chemical analysis of dental hard tissues determines alterations in ion levels with age, whereas the histological and chemical methods are invasive methods requiring extraction/sectioning of the tooth. In this chapter, the different techniques and considered studies were overviewed in conjunction with their advantages and disadvantages. It needs to be taken into consideration that rather than restricting on one age estimation technique, using the other available techniques additionally and performing repetitive measurements may be beneficial for accurate age estimation.

“…The extent of this root translucency may be determined by computer mapping of serial hard tissue sections of the tooth. Regression tables prepared from large numbers of teeth of known age have been used to show that it is possible to determine the age of an unidentified body within about 7 years of the correct at death [24].…”

Role of Dentist in Forensic Investigations

Teeth can be used as a weapon of attack or defense. Dentistry has much to offer to law enforcement agencies in the uncovering and solution of crime. The permanent teeth develop throughout the first two decades of life, and physiologic variations, pathologies, and effects of dental therapy may be recorded in the hard tissues of the remaining dentition throughout life and beyond. It is the role of the dentist to help extract this information and use it in the identification of the unknown body. Human teeth and dental restorations have proven to remain stable during a long time as well as in extreme situations such as fire. Therefore, dentist can play an important part in the identification of severe mutilated bodies of unknown persons. The teeth may also be used as weapon and, under certain circumstances may leave information as to the identity of the biter. Analysis of bite marks is the second major responsibility of the forensic dentist. The general practitioner has a major role to play in providing the accurate dental records on which much of forensic activity is based.
