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 …
