Introduction: Dermatoglyphics is focused on studying the fine-patterned dermal ridges on volar surfaces of soles, palms, and ridges. It has drawn attention in the field of dentistry. The diagnosis of many diseases that are genetically or nongenetically determined can now be aided by dermatoglyphic analysis, as these patterns have polygenic inheritance. Millions of people consume tobacco, but all of them do not suffer from potentially malignant disorders (PMDs) of the oral cavity. It seems likely that a genetic predisposition could be an underlying mechanism. Aim: The present study aims at determining the relationship between dermatoglyphics and oral leukoplakia (OL). Materials and Methods: Fingertip prints were studied on 30 subjects who were divided into three groups: Group 1 consisted of 10 patients with leukoplakia; Group 2 had 10 patients with habit without lesion; and Group 3 had 10 patients without any habit and any lesion as control. Fingertip prints were taken by the ink method. Results: It was observed that the loops pattern was predominant in patients with OL and in patients with habit but without lesion.

| Introduction|| |
Dermatoglyphics is an old science and it was established by Galton in the year 1892. It was Cummins and Midlo who coined the term “Dermatoglyphics” in 1926; which is a branch of genetics dealing with the skin ridge system. These patterns of the hand are no longer restricted to palmistry. Through constant effort by eminent researchers, these patterns now play an important role in the diagnosis of several medical and genetic disorders. Dermal ridge patterns are formed embryologically between the 10th and 17th weeks of life; hence, the dermatoglyphic traits may reflect prenatal developmental stability. Most importantly, they remain constant from before birth until death and they are unaffected by any constitutional or environmental disturbances during the remaining gestative period. Carter and Matsunaga have postulated that abnormalities in dermal ridges can only appear when a combination of hereditary and environmental factors exceeds a certain level and leads to changes in the local environment, including an inadequate blood/oxygen supply and alterations in the epithelial growth patterns.
OL is one among the important potentially malignant disorders of the oral mucosa. It has been defined as “a predominant white lesion of the oral mucosa that cannot be characterized as any other definable lesion.” The etiology of OL is considered multifactorial, but smoking is appreciated as being a frequently involved factor. OL is much more common among smokers than among nonsmokers. Alcohol is believed to be an independent risk factor, but definitive data are still lacking.
Epidemiological and experimental evidence indicates a causal relationship between tobacco (smoking and nonsmoking) and OL. Only a fraction of people exposed to these agents develop OL. Genetically determined differences among these individuals would explain their susceptibility. Hence, the present study was conducted to analyze the qualitative variations among tobacco users without any lesion and the ones having OL.
| Materials and Methods|| |
The present study comprised total 30 patients, and they were divided into the following groups. The clinically diagnosed cases of OL were included in the study.
Group I: 10 patients with clinically diagnosed oral leukoplakia.
Group II: 10 patients with habit without lesion
Group III: 10 individuals without any habit and lesion as control group
Materials used for obtaining fingerprints
- - Blue duplicating ink (Camel Ink)
- - Good quality A4 sheet white paper
- - Soap, water, and towel
Procedure for obtaining prints
Patients’ hands were cleaned and dried before printing. A thin layer of blue printing ink was applied to the fingers of these patients. Imprints of five fingertips were taken on the middle of an A4 sheet. The same procedure was repeated for other hand. Prints were dried and studied by using a magnifying lens to identify the fingertip pattern. After taking the fingerprints, ink was removed by using oil, soap, and water. Then, the fingerprints were analyzed qualitatively.
| Results|| |
In patients with leukoplakia, habitual patients without lesion, and control patients, total 300 fingerprint patterns were assessed. In group 1, 100 fingerprint patterns were assessed. Among them, 57 (57%), 40 (40%), and 3 (3%) were loops, whorls, and arches, respectively. In group 2, 100 fingerprint patterns were assessed. Among them, 66 (66%), 28 (28%), and 6 (6%) were loops, whorls, and arches, respectively. In group 3, 100 fingerprint patterns were assessed. Among them, 34 (34%), 62 (62%), and 4 (4%) were loops, whorls, and arches, respectively [Table 1]. In group 1 and group 2, loops were predominant; in group, 3 whorls were predominant. Thus, in the present study, loops were predominantly seen in group 1 and group 2 compared with group 3 and whorls were predominantly seen in the control group compared with group 1 and group 2. There was no significant difference seen in all three groups related to arches.
| Discussion|| |
In 1936, Dr. Harold Cummins proved certain unique, consistent dermatoglyphic changes in several children with trisomy 21 (Down’s syndrome) that were absent among controls. This unique discovery helped to move the budding science of dermatoglyphics from a place of obscurity to being acceptable as a diagnostic tool among medical personnel. Since then, widespread interest in epidermal ridges developed in the medical field since it became apparent that many patients with chromosomal aberrations had unusual ridge formations. The inspection of skin ridges, therefore, seemed a promising, simple, and inexpensive means for determining whether a given patient had a particular chromosomal defect. With an ever-growing population, it becomes important that methods be developed, to identify individuals either at risk for or already having a given illness in the most cost-efficient manner without sacrificing quality of care. The use of dermatoglyphics is rather a unique and extremely useful tool for preliminary investigations into conditions with a suspected genetic base.
In the present study, loops were increased in patients with OL compared with control, which are in agreement with the findings of Lakshanika et al., David et al., Singh et al., Venkatesh et al., and Awasthy et al. but not in agreement with the findings of Darna et al. and Patil et al. Whorls were increased in the control group as compared with patients with OL, which is similar to observations made by David et al., Singh et al., Venkatesh et al., and Awasthy et al. but not in agreement with the findings of Lakshmana et al. and Patil et al. Loops were also increased in patients with habit without lesion as compared with the control. These findings correlate with the findings of Awasthy et al. and Aditya et al.
Tobacco in any form is a known risk factor for OL. Substantial evidence also suggests that the carcinogenic process is driven by the interaction between exposure to exogenous carcinogens and inherent genetic susceptibility. In response to environmental exposure, genetic damage accumulates more quickly in individuals with genetic susceptibility to DNA damage than in those without such instability but with a similar exposure. Consequently, individuals with genetic instability might be at a greater risk for developing these lesions. It is also suggested that many genes that take part in the control of finger and palmar dermatoglyphic development can also give indication to the development of premalignancy and malignancy. Hence, identifying people at high risk for OL could be of great value to decrease the incidence of the future risk of oral cancer.
| Conclusion|| |
In the present study, loops were a predominant pattern in patients with leukoplakia. Thus, it can be said that dermatoglyphics has shown promising results in determining the individuals with genetic susceptibility to develop OL. This may help us to identify individuals with or at risk for developing OL and oral cancer, so that preventive measures can be taken as early as possible to prevent their occurrence.
