  author={K Manjunath and Gopu Sriram and T. R. Saraswathi},
Dental enamel is the highly mineralized tissue in the human body and resists post mortem degradation. Tooth prints are the enamel rod end patterns on tooth surface. In this study, acetate peal technique is used to record enamel rod end patterns on tooth surface. Microphotograph of the acetate peel imprint is subjected to biometric analysis using Verifinger standard SDK 5.0 to obtain the pattern of enamel rod ends (tooth prints). 30 extracted tooth were selected, and tooth prints were obtained…

Analysis of Enamel Rod End Patterns on Tooth Surface for Personal Identification—Ameloglyphics
Visual analysis showed that wavy branched subpattern was the predominant subpattern observed among examined teeth, and ameloglyphics is a reliable technique for personal identification.
Analysis of enamel rod end pattern for personal identification
Wavy branched pattern was found to be the most predominant pattern in incisors, canines and first premolars in the authors' study and can be used as a valuable inexpensive tool in forensic odontology for personal identification.
Analysis of Enamel Rod End Pattern at Different Levels of Enamel and itsSignificance in Ameloglyphics
It is revealed that each enamel rod end pattern takes approximately 4-6 years to change into the subsequent pattern due to in vivo brushing, so the enamel rods end pattern should record for at least every 4 years during its practical application.
Efficacy of various materials in recording enamel rod endings on tooth surface for personal identification
Cellulose acetate film is a reliable material for recording enamel rod endings on tooth surface for personal identification compared with cellophane tape and light body rubber-base impression material.
Ameloglyphics: A possible forensic tool for person identification following high temperature and acid exposure
The tooth prints from the same tooth after it was exposed to acid or heat were reproducible and showed high to very high similarity with the original tooth print of that particular tooth stored in the database.
Enamel print pattern in Deutero-Malay sub race based on extracted female permanent maxillary central incisors
The enamel print pattern in every central incisor has no similarity; hence can be a possible tool for personal identification.
Scanning Electron Microscope Corroboration of Ameloglyphics – A New Tool in Forensic Odontology
Ameloglyphics is a sensitive and reproducible scientific tool that can be utilized for the management, examination, and evaluation of dental evidence for identification at crime scene and disaster sites and its importance vis-a-vis fingerprints cannot be understated.
Can dead man tooth do tell tales? Tooth prints in forensic identification
It is observed that comparing two tooth prints taken from an individual at two intervals exhibited similarity in many cases, with wavy pattern tooth print being the predominant type, however, the same prints showed dissimilarity when compared with other individuals.
Ameloglyphics: A Novel Appraisal of the Enamel Structure in Identification of an individual
The carious teeth and deciduous dentition showed predominance of wavy and straight pattern which is in accordance with their softer nature and increased susceptibility to bacterial invasion.

Quick preparation of peel-prints for sedimentary petrography
ABSTRACT Acetate peels made from sheets of commercial acetate film are quicker, easier, and less expensive to prepare than peels made by the old acetate solution method. Textural details of polished
The autodegradation of deoxyribonucleic acid (DNA) in human rib bone and its relationship to the time interval since death.
The DNA degradation rate may vary with temperature and humidity more than it varies between individuals, and when the samples were incubated under identical conditions, the degradation rate of DNA in samples from different individuals appeared very similar.
