Can Dermatoglyphics Be Used as a Marker for Predicting Future Malocclusions?

Area of Science:

• Orthodontics
• Genetics
• Forensic Science

Background:

• Dermal ridges and craniofacial structures originate from shared embryonic tissues.
• This shared origin suggests a potential link between dermatoglyphics and skeletal malocclusions.
• Early detection of malocclusions can potentially avert surgical interventions.

Purpose of the Study:

• To investigate and compare dermatoglyphic characteristics among different skeletal malocclusion classifications.
• To explore potential associations between fingerprint patterns and facial skeletal anomalies.

Main Methods:

• A cross-sectional study involving 323 orthodontic patients.
• Participants categorized into Skeletal Class 1 (n=163), Skeletal Class 2 (n=111), and Skeletal Class 3 (n=49) based on Angle's classification.
• Analysis included total ridge counts (TRC), atd angles, a-b ridge counts, fingerprint patterns, and hand asymmetry, using chi-squared, ANOVA, or Kruskal-Wallis tests.

Main Results:

• A statistically significant difference was observed in the left a-b ridge count between Skeletal Class I and Skeletal Class III patients (p=0.049).
• The loop pattern was most prevalent across all groups, while arch patterns were least frequent.
• No significant differences were found for other analyzed dermatoglyphic parameters.

Conclusions:

• Minor dermatoglyphic variations were noted among different skeletal malocclusions.
• However, most palm and fingerprint characteristics did not demonstrate significant differences to reliably distinguish between malocclusion types.
