    Abstract

    [Truncated] The sequential process of dental development and the progressive degenerative changes in teeth form the basis of numerous forensic age estimation methods. The positive correlation between the deposition of secondary dentin along the walls of the pulp chamber and age has been previously researched and yielded promising results. The pioneering work by Kvaal et al. (1995) and Drusini et al. (1997) has developed age estimation techniques for adults that are simple and non-invasive, thus suitable for application in living individuals and dry skeletal remains. Similarly Moorrees et al. (1963a,b) developed a non-invasive approach to estimate age in subadults by scoring dental development in permanent and deciduous dentition. Previous research has indicated that the accuracy of age estimation techniques increases with the use of population specific standards. This study, therefore, aimed to apply the aforementioned techniques to Western Australian and Central Indian populations and develop population specific age estimation standards. The thesis is presented in five parts comprising literature reviews (Part I) and three independent studies (Parts II to IV) that focus on age estimation methods based on secondary dentin deposition and dental development; Part V summarises the projects and concludes the thesis.

    Part I introduces the thesis and included chapters on basic dental anatomy and histology. This was followed by a review of the significant rulings regarding expert evidence testimony, which emphasized the need for quality assurance in forensic research. Lastly, literature relevant to the age estimation methods based on secondary dentin deposition and dental development was reviewed, including the validation studies of the Kvaal et al. (1995) and Moorrees et al. (1963) methods in other populations.
