Aging An Ancient Maya Population From Actuncan, Belize Using Dental X-Rays, Kaitlyn Nicole Cash
Aging An Ancient Maya Population From Actuncan, Belize Using Dental X-Rays, Kaitlyn Nicole Cash
Honors Theses
My goal is to determine an accurate age at death estimation of an ancient Maya population from the archaeological site of Actuncan, Belize. This was done by measuring the lengths of the coronal pulp cavities in the individuals’ teeth. I used X-Ray images to measure the coronal pulp cavities of the teeth and estimated age using multiple regression formulae for premolars, molars, and incisors to make age estimations. The formulae came from two studies, Ikeda et al. (1985) and Drusini (2008), that form the basis of my research. Ikeda et al. (1985) was the first to use this aging method, …
Development Of A Non-Invasive Dna Extraction Method From Teeth, Monalisa Heng
Development Of A Non-Invasive Dna Extraction Method From Teeth, Monalisa Heng
Honors Theses
Forensic dentistry has evolved from simple morphological investigations to genetic and molecular analysis. One of the most important techniques is DNA analysis which requires viable samples from an individual or crime site. The orofacial region can be a good source for DNA samples because the tissues can resist environmental, thermal, electrical, and mechanical challenges. Teeth are especially useful as a source of genetic material because the DNA located in the pulp is surrounded by protective mineral tissue. The DNA in the pulp tissue is currently accessed through destructive methods involving crushing, pulverization, and splitting the tooth. Unfortunately, destructive methods destroy …
A Nondestructive Procedure For The Extraction Of Dna From Human Teeth, Mark Reliquias, Ann-Elodie Black
A Nondestructive Procedure For The Extraction Of Dna From Human Teeth, Mark Reliquias, Ann-Elodie Black
Honors Theses
This research focuses on constructing a procedure that allows for the nondestructive extraction of mtDNA from teeth for forensic DNA analysis. Currently, only a destructive method for extracting DNA from teeth is used in the forensic laboratory to identify an individual. A disadvantage of extracting DNA through a destructive method is the complete or partial loss of the tooth. To extract DNA through a destructive method, the tooth must either be cut horizontally or vertically to access the pulp, or the root ground into a powder to extract DNA from the dentine-cementum. With the destruction of the tooth, additional forensic …
Analysis Of Dental Management Of Those With Physical And Mental Disabilities, Ashley M. Fleck
Analysis Of Dental Management Of Those With Physical And Mental Disabilities, Ashley M. Fleck
Honors Theses
Those with physical and mental disabilities are at an increased risk of oral complications such as gingivitis and periodontal disease. In comparison with this risk, this population struggles to access appropriate dental care that accommodates those with disabilities. This thesis reviews the demographics of those with special needs, dental education barriers to working with this population and financial barriers that hinder access to care. An overview of the oral health problems of common disabilities is presented as well as behavioral management techniques that could be easily implemented in the dental office. A general review of good oral hygiene for those …
