Comparison of dermatoglyphic patterns in oral leukoplakia and oral submucous fibrosis patients

Background: Genetics plays an important role in the detection of an Oral potentially malignant lesion. A major contributor to genetic study is Dermatoglyphics or the study of fingerprints and lines of palmer and plantar surfaces. Many researchers have used dermatoglyphics to connect genetics with oral lesions and malignancies. Thus, the current study has been conducted to find out an association between dermatoglyphic patterns and oral leukoplakia, oral submucous fibrosis and healthy subjects.Methods: The present study is conducted on subjects that have been already diagnosed with oral lesions. Fingerprint patterns (whorled, loop and arch) were evaluated by utilizing fingerprints.Results: The present study showed that the loop pattern was common in all three subjects. The frequency of whorled and arch pattern is decreased in oral leukoplakia and oral submucous fibrosis that healthy subjects. Arch pattern is comparatively decreased in subjects with oral leukoplakia than oral submucous fibrosis and there is a decrease in the frequency of whorled patterns in OSMF as compared to oral leukoplakia.Conclusions: Authors conclude that simply by observing the whorled and arch patterns in a subject, authors can hypothesize that risk of occurrence of oral leukoplakia and oral submucous Fibrosis and take preventive measures against the said lesions.

Correlation of dermatoglyphics with emotional intelligence amongst medical students

Background: Dermatoglyphics is the study of patterns of epidermal ridges on the volar surfaces of the skin. Thisis said to be associated with multiple intelligences in humans based on the fact that the neocortex anddermatoglyphic prints are developing simultaneously during embryogenesis and they are both geneticallydetermined. Hence this cross-sectional observational study to correlate Emotional Intelligence and dermatoglyphicpatterns.A self-evaluating questionnaire was applied on 100 M.B.B.S students, fingerprints of whom were collected using‘Ink and Paper’ method. The subjects were then categorized into two groups- Category A including subjects withEQ>120; and Category B including subjects with EQ<120. The collected fingerprints were categorized into PlainArches, Tented Arches, Ulnar Loops, Radial Loops, Whorls and Composite. The data was then tabulated andobserved for recurrence of patterns in each category of EQ and was statistically analyzed.Results: In Category A, the most recurring pattern is Ulnar Loop. In Category B, the most recurring fingerprintpattern is Ulnar Loop in all digits except the L4 and R4 in which Whorl is the most recurring type. The chi squaretest of significance and exact test of association were applied and ‘p’ values were calculated and none of themwere <0.05.Conclusion: The results correspond with the observations made in a previous study correlating dermatoglyphicsand IQ amongst medical students. Hence, the aforementioned results may be suggestive of some correlationbetween dermatoglyphics and EQ. However, the lack of statistical significance may be attributed to the modestsample size. Further research is required in this regard to validate the results of this study.

Evaluation of dermatoglyphic patterns using digital scanner technique in skeletal malocclusion: A descriptive study

Skin is the largest human organ, which performs a dynamic role in life. The ectodermal layers of the skin found on the palm with intricate lines are stable throughout life and have grabbed scientific attention. Any disturbances during their formation might possibly have the likelihood of a person developing malocclusion. Aims and Objectives: The aims of this study were to evaluate and compare the dermatoglyphic pattern with various skeletal malocclusions. Materials and Methods: The study was carried out on 40 outpatients reported with an age group of 18–20 years divided into four groups as follows: Group: I – 10 (Class I occlusion), Group: II – 10 (skeletal Class I malocclusion), Group: III – 10 (skeletal Class II malocclusion), and Group: IV – 10 (skeletal Class III malocclusion). The fingerprints were recorded using scanner exclusively designed for diagnostic purpose of the study. The collected data were analyzed using SPSS statistics software Version 23.0 to find which groups had significant differences. Results and Conclusion: Increased frequency of arch pattern was present in participants with Class I malocclusion, and loop patterns were observed in those with Class I occlusion and Class III malocclusion and whorl patterns in Class II malocclusion with P < 0.05. Dermatoglyphic pattern remains constant throughout life and it can be used as a noninvasive aid in determining the development of malocclusion at a very early age.
