Introduction: There are several studies in relation to DERMATOGLYPHICS with some fields in dentistry. The objective of this study is evaluation of relation between DERMATOGLYPHICS and hypodontia in cases with congenital hypodontia.Materials & Methods: In this case-control study, 20 cases with hypodontia and 20 cases as control group were selected from those referred to Mashhad Dental School. Ink method was used in this study. Data analyzed with SPSS, and T-test with significancy of 0.05 was used for statistical analyses.Results: T-test showed no significant difference between the mean number of ridge count in the left and right hands of the subjects..T-test showed significant difference between both groups in frequency of loop pattern type of the finger tips. (P=0.01). Also there is no significant difference between both study groups in frequency of types of arch and whorl patterns of the finger tips.Conclusion: DERMATOGLYPHICS may be considered in diagnosis of hypodontia; however further researches in large groups especially according to DERMATOGLYPHICS' qualitative characteristics in cases with congenital hypodontia is needed.

BACKGROUND: There are controversial evidences on the association between fingerprint traits and schizophrenia. We compared fingerprint traits of patients with schizophrenia and normal individuals in Iranian population.METHODS: Finger tip dermal ridge of 290 patients with schizophrenia and 290 normal subjects were studied for four dermal traits. Data was analyzed with Pearson correlation and student's tests.RESULTS: Finger print patterns and secondary creases were not significantly different between the two groups (p>0.05).Although mean ridge counts of left and right index fingers of the case group were greater than the control group (p<0.05), these differences were not significant in females.CONCLUSIONS: Probably the left index ridge counts and fluctuating asymmetry in schizophrenic patients are different from those of the normal population. This difference may serve as a diagnostic biological marker for screening people susceptible to schizophrenia. Further studies are needed to determine predictive value of fingerprint trait as a biomarker for the schizophrenia.

The study of patterns of fingerprints is important in anthropology and medical genetics, chiefly because of their diagnostic usefulness. In the present work, we studied the frequencies of various types of skin ridges of the first phalanx in patients with sever oligospermia or azospermia. In a double-blind case-control study, we determined the frequencies of fingerprints in 880 first phalanxes belonging to 48 men with sever oligospermia and 40 men with azospermia. We determined the types of fingerprints based on Galton classification. Also their FRC, TFRC and AFRC were calculated. Then the results were compared with each other and general population as control group. The most frequent type of fingerprint in both case groups was "Loop". Frequencies of different types among two groups of cases were statistically different (P<0.005). Also they were statistically different with general population (P<0.005). The largest mean of FRC in men with oligospermia was belonging to the left ring fingers (23.1) and the second to the right thumbs (21.91). The largest mean of FRC in men with azospermia was belonging to the right thumbs (23.6) and the second to the right ring fingers (22.6). The mean of TFRCs in men with oligosoermia and azospermia were 106.8 and 114.39, respectively, and the mean of AFRCs in those two groups were 14 and 11, respectively; their differences were not statistically significant. It can be concluded that qualitative feathers of the fingerprints of men with oligospermia and azospermia were different with each other and with general population. And quantitative feathers of the fingerprints in those two case groups were statistically different as well.

Systemic arterial hypertension is a clinical condition of great risk in the development of cardiovascular diseases and it has a high impact on public health. The disease is influenced by modifiable and non-modifiable factors. In that context, DERMATOGLYPHICS is a method of analysis of fingerprints as a mark of biological individuality and that can be related to health, sports, and the prognosis of diseases due to being able to point out the individual with the potential to develop certain diseases. This study aimed to investigate the characteristics of the fingerprints of women with systemic arterial hypertension by comparing them with a control group, which does not present the disease. Thus, we intend to find a dermatoglyphic pattern for Brazilian women with systemic arterial hypertension. The sample in the study consisted of 732 women, 366 with a positive clinical diagnosis for systemic arterial hypertension, and 366 individuals forming a control group, which did not present systemic arterial hypertension. All individuals in the sample are of equivalent age and the fingerprints were collected from all fingers. The method used to determine the profile of the individuals is the computerized dermatoglyphic. It was used, for the collection of fingerprints, of the Dermatoglyphic Reader®, which presents results of 400% more precision. There was a statistically significant difference between the groups, and when the Adjusted Residue Analysis was performed, the Ulnar Loop figure on fingers 4 and 5 of the left hand, and fingers 1 and 5 of the right hand, was predominant in the group of women with hypertension. These results demonstrate the existence of a dermatoglyphic mark, characteristic of patients with systemic arterial hypertension. Therefore, it can be concluded that the analysis of fingerprints of the hands by the Dermatoglyphic method can demonstrate the potential that women could have developing systemic arterial hypertension.

Although fingerprints and handprints are widely used in criminology, it is only recently that this approach has been applied to the field of medical and genetic diagnosis. In order to investigate DERMATOGLYPHICS in Insulin Dependent Diabetes Mellitus (IDDM), quantitative and qualitative characteristics were analyzed in 30 diabetic patients and 30 normal subjects. The X 2 test was used for quantitative and t - test for qualitative data analysis. The results showed finger line counts (ab count) in the males and females of diabetic patients compared to control subjects decreases but this reduction was not significant. The forms of Loop and Whrols are heterogenous and compared to control group were significant (P= 0/001, P= 0/004). In conclusion, DERMATOGLYPHICS seem to be an interesting tool for genetic studies related to IDDM.      

Aims Dermatoglyphic is the study of skin patterns on hands and feet. It has been shown in some studies that specific finger patterns could be a risk factor for breast cancer. Thus, this study aims to evaluate fingerprint patterns and other easy-to-obtain features in the risk of breast cancer. Instrument & Methods This descriptive study was conducted in 2020. A dataset containing 462 records included female patients in Imam Khomeini Hospital Complex, Tehran, Iran. The factors’ weight was determined by the Information Gain index. Predictive models were built once without fingerprint features and once with fingerprint features using Naï ve Bayes, Decision Tree, Random Forest, Support Vector Machine, and Deep Learning classifiers. RapidMiner 9. 7. 1 Software was used. Findings The most important factor determining breast cancer were age, having a child, menopause situation, and menopause age. The best performance was the Random Forest model with accuracy and Area under Curve of a Receiver operating characteristic of 84. 43% and 0. 923, respectively. The fingerprint patterns feature increased the RF accuracy from 79. 44% to 84. 43%. Conclusion An early breast cancer screening model could be built with the use of data mining methods. The fingerprint patterns could increase the performance of these models. The Random Forest model could be used. The results of such models could be used in designing apps for self-screening breast cancer.

Introduction: Insulin-dependent diabetes mellitus (IDDM) or type 1 diabetes is an organ-specific autoimmune disease that caused by destruction of insulin - producing beta cells of the pancreas. Etiology of this disease is still unknown. It is seen that genetic and environmental factors play an important role for susceptibility to develop type 1 diabetes. The relationship between HLA associated factors and susceptibility to IDDM disease, was reported by several investigators. Also, some studies show that DERMATOGLYPHICS is associated with type 1 diabetes. However, it is maybe there is an association between HLA and DERMATOGLYPHICS inpatients'with type 1 diabetes and these characteristics could be applied for diagnosis of disease.Materials and Methods: In this study, the prevalence of HLA (with using standard microlymphocytotoxicity method) and DERMATOGLYPHICS determined in 30 Iranian patients with IDDM and 30 normal healthy controls with similar ethnic background and the same geographical area.Results: A significantly higher frequency of HLA-DQ, A2, DR3 and DQ2 were found in IDDM cases compared to the controls. The results obtain from DERMATOGLYPHICS showed that line ab was reduced in male and female type 1 diabetes. The reciever operating chractristics curve showed that the positive point for lines ab in right and left hands were 34.7 and 35.25, respectively.Discussion: There is no association between HLA and DERMATOGLYPHICS.With considering of genes encoding of HLA separated from genes determining DERMATOGLYPHICS, HLA typing and DERMATOGLYPHICS seem to be interesting tools for genetic studies related to type 1 diabetes. Further studies are recommended in order to provide more insight into the susceptibility to this disorder.
