Dermatoglyphic Analysis Of Finger Tip Patterns In Children With Hearing And Speech Disorder

Abstract

Dermatoglyphics, the study of dermal ridge patterns is the gold standard reliable means of personal identification as they are unique and lifelong markers of human identification. Various studies have found a positive correlation between dermal patterns and caries in children, but very little researches have been done on special children.

Aim:

This study aims to assess the dermal patterns and its correlation with the caries and gingival status among 6 to 12 years old hearing and speech-impaired children.

Methodology:

One hundred students attending special school for hearing and speech impaired children participated in the study. Using the Cumin and Mildo method, the thumb impressions of both thumbs were taken with the help of an ink pad and paper. This was then divided into the three basic fingerprint patterns i.e., Arch, Loops and Whorl. A thorough oral screening was conducted. Data such as the children’s oral hygiene index simplified and DMFT were recorded and statistically analyzed using the chi-square test.

Conclusion:

Loop pattern was the most predominant followed by the whorl pattern among the study participants but it was statistically insignificant. The arch pattern was the frequently seen pattern in children with a high caries value when compared to loop and whorl though it wasn’t statistically significant. Oral hygiene status was almost similar for all the patterns.
