Palmistry: a tool for dental caries prediction!

Area of Science:

• Genetics and Human Biology
• Pediatric Dentistry
• Forensic Odontology

Background:

• Dermatoglyphics offers a valuable preliminary tool for investigating genetic conditions.
• Dental caries is a multifactorial disease with genetic influences, necessitating early risk prediction in children.
• Identifying high-risk children allows for timely and effective preventive dental care.

Purpose of the Study:

• To investigate the genetic component of dental caries using dermatoglyphics.
• To establish a cost-effective method for assessing caries risk in field studies.
• To correlate dermatoglyphic patterns with the incidence of dental caries in young children.

Main Methods:

• Examined 336 kindergarten children (3-6 years old) divided into caries-free and caries groups.
• Recorded dermatoglyphic patterns (ulnar loops, whorls) on fingertips and df scores.
• Utilized SPSS software and test of proportions for statistical analysis.

Main Results:

• Caries-free children, particularly females, predominantly displayed ulnar loops.
• Children with dental caries showed a higher prevalence of whorls (2:1 ratio), more common in females on the left 3rd digit and males on the right 3rd digit.
• A low total ridge count was observed in the caries group, especially in males.

Conclusions:

• Dermatoglyphic patterns can serve as an indicator for dental caries susceptibility.
• Ulnar loops are associated with caries-free status, while whorls indicate a higher risk.
• These findings support the use of dermatoglyphics for early caries risk assessment in pediatric populations.
