Unveiling the Science of Fingerprints in Forensic Medicine

Dr. Krup Vasavada introduces the topic of dactylography, explaining its significance in forensic science as a method of identification. The video covers the principles of fingerprint formation, the constancy of patterns, and the uniqueness of fingerprints. It details methods for recording fingerprints, including plain and rolled methods, and discusses types of evidentiary fingerprints: patent, plastic, and latent. The video concludes with a classification of fingerprint patterns, highlighting the commonality of loops, rolls, arches, and composites.

What is the primary principle behind the uniqueness of fingerprints?

• The arrangement of papillary ridges is unique and constant.

• Fingerprints are identical for everyone.

• Fingerprints are formed by random patterns.

• Fingerprints change over time.

Which method of fingerprint recording is quicker but provides a smaller surface area for comparison?

• Rolled method

• Plain method

• Digital method

• Laser method

What is the main disadvantage of the plain method of fingerprint recording?

• It requires special equipment.

• It is difficult to perform.

• It is time-consuming.

• It does not capture a large surface area.

What type of fingerprint is visible without any processing and is often made from substances like grease or blood?

• Latent print

• Patent print

• Digital print

• Plastic print

Which type of fingerprint requires additional processing to be made visible?

• Patent print

• Plastic print

• Visible print

• Latent print

Which type of fingerprint is an indentation in a soft surface like butter or soap?

• Patent print

What percentage of fingerprints are classified as loops?

• 25%

• 65%

• 0.7%

• 2-3%
