| Summary: | Introduction: Dermatoglyphics is the study on edpidermal
ridges on the palmar and plantar surfaces of the feet and hand.
Embryological development of orodental structures and these
dermal patterns occur during the same period. The environmentally
influenced genetic predisposition is found in different types of
malocclusions. This malocclusion should also exhibit different
dermal patterns which are unique for each class.
Aim of the Study: The present study was conducted to compare the Dermatoglyphics parameters of individuals with normal
occlusions and various classes of malocclusions.
Methodology: The participants were divided into four groups;
Group 1: class I ideal; Group 2: class I malocclusionl; Group
3: class II Div 1 and Div 2; Group IV: class III. The finger and
palmar prints were obtained and they were analyzed for each
type of pattern. The Total Finger Fridge Count (TFRC), a-b ridge
count and the angle “atd” (angle formed by connecting lines from
digital triradius ‘a’ to the axial triradius and from this triradius to
the digital triradius ‘d’) were associated with particular groups.
Results: The data was entered and analyzed by using Students
t-test and ANOVA.
Conclusion: Particular predictive occurrence of patterns was
not found to be associated with each group. However, some
of the finger patterns, such as increase in twinned loops in
class II malocclusions and absence of radial loops in class III
malocclusions were found to be statistically significant (p<0.001).
The parameters associated with palmar prints had no statistical
significance. Further studies with more samples in each group
should be carried out. |
