Dermatoglyphics: A Noninvasive Diagnostic Tool in Predicting Class III Skeletal Malocclusion in Children.

BackgroundDermatoglyphics is a scientific study that deals with the epidermal ridges and their configurations on certain body parts such as fingers, palms, and soles. In humans, during the intrauterine life (IUL) the primary palate, lip, and dermal ridges are formed during the same period, the genetic code engineered in the genome normal or abnormal is mirrored on these developing structures. Thus making dermatoglyphic a preceding tool in dental diagnosis.Aims and objectivesThe study aimed at evaluating dermatoglyphics as a tool in diagnosing malocclusion by comparing qualitative and quantitative dermal patterns in class I and class III skeletal malocclusion.Materials and methodsSixty subjects fulfilling inclusion-criteria were segregated into two groups, group I (class I skeletal malocclusion) and group II (class III skeletal malocclusion) with 30 subjects in each group. Dermatoglyphic patterns were recorded using ink method following rolling impression technique on recording sheets. The dermatoglyphic data were assessed for different finger ridge patterns, total finger ridge count, a–b ridge count, and atd angle.ResultsThe data were analyzed using Chi-square and paired t tests. In skeletal class III malocclusion, there was an increase in loop count and a decrease in the count of whorls and arches as compared to class I malocclusion (p = 0.037). However, in relation to total finger ridge count, a–b ridge count, and atd angle, there was no statistically significant difference found between the groups.ConclusionThe end of the study derived that the fingerprint patterns are valuable and ineradicable markers of malocclusion. Thus, the dermatoglyphics can be utilized as a screening tool for early prediction of skeletal class III malocclusion at a younger age-group. Further studies are suggested with the inclusion of other parameters using the inkless biometric method in different populations.How to cite this articleBelludi AC, Sridhara A, Kumar NC, et al.

Dermatoglyphic Patterns of Children with Special Educational Needs

Background: The present study aimed at finding the finger and palmar dermatoglyphic patterns of students in special school and to discover whether significant dermatoglyphic features exist in students in special school. Materials and methods: Finger and palm prints were taken from 100 students from Garden City Special School which served as the study group and 100 students from “In Him is Life School” which served as the control group. Analysis of quantitative and qualitative traits of dermatoglyphs (Total Finger Ridge Count, atd angle, pattern type, symmetry of palmprint and type of PIC) were performed. Descriptive statistics were used to determine the differences among the groups. Results: Central pocket loop whorl (CPLW) which is an indicator in people with better academic performance was significantly lower (P<0.0001) in individuals in the special school (SS). The atd angle was significantly higher (P<0.0001) in both hands in SS than in CG. The current study revealed that the prevalence of symmetrical PIC was significantly lower (P=0.012) in the SS (39%) compared to CG (67%). Conclusion: Students in special school have unique dermatoglyphic pattern. There were significant differences in certain types of dermatoglyphic pattern observed in students in special school compared to students in normal school. Further study is required to have a baseline data which can serve as a diagnostic tool for early detection of people who need special attention.

These correlations may have an essential role in the early diagnosis of reproductive dysfunction in the future.

A case-control study on relationship between dermatoglyphics and diabetes

Nowadays study of dermatoglyphics has an extraordinary significance in legal and criminal explores. Additionally, its investigation is identified with some hereditary sicknesses has an enormous application. Diabetes Mellitus is the silent killer of humanity and general medical issue. Dermatoglyphics might be viably utilized as a screening methodology in future and may help in the early recognition of instances of diabetes mellitus. In our study, total of 100 patients were selected from the out door patient department from the hospital, out 0f 100 patients 50 patients those are suffering from diabetes made the experimental group and the other those are having no systemic condition made the other group or the control group. The establishment of the connection between the two groups by examining the each group the fact of presence or absence of dermatoglyphic design. In this total finger ridge count, indian ink technique was usd for taking up the hand, along with total ridge count of finger, absolute finger ridge count, ridge count for distal as well as lateral deviation along with palmer frequency design computerised along with lateral deviation with design frequency of the c- line and angles, which represent the qualitative boundary. The result that has been obtained from our study reveals that the total finger count of the ridge along with ridge count of the finer absolute, along with a-b count of the ridge were found to be higher in all the groups of the patient but found to be insignificant statistically. Angle “atd” that is present over both the sides of the hand in the patient were found to be expanded in all the groups that involve both the experimental groups and the control group, but with an exception in males that too in left side, but still they differ on the right side that too significantly (p<0.01, overall) and on the left side i.e. in case of females with p<0.001. The angles of tad and as well as ‘tda’ which were present over the two sides of the with respect to all the groups, that include the experimental one and the control one, but with an exception with respect to males with left ‘tda’ and in other case they significantly differ in case of females with left tad with p<0.01 and in case of right side tda with p<0.001 and with respect to all the groups with reference to right ‘tda’ with value of p<.01 the arch advanced frequencies along with the circle and the whorl in case of females with respect to the over all groups with an exception with loop were found to be increased significantly with p value i.e. p<0.05. The design of the spiral along with remnant were found to be totally limited to the thenar along with the hypothenar region in the male patients when get contrasted with the controls. By the results of our study we concluded that, there is expansion in the radial variety and absence was found in case of proximal variety and the designs of the c – line in case of diabetics were reduced when it is compared to the control group. Our study results demonstrated that dermatoglyphic abnormalities can be utilized as a device which act as analytic for predicting the chance for the development of the disease known as diabetes in future.

Finger-ball dermatoglyphics and its indices among Bhil population of Udaipur, Rajasthan

Many years ago, the research on epidermal ridges was published by Cummins and Midlo (1943). Cummins and Midlo also coined the term dermatoglyphics (derma- skin, glyphe- carvings) for the scientific study of ridges. The purpose of the present study is to know various finger- ball patterns of 200 Bhil individuals (male-100 & female- 100) of tehsil Burgeon, Udaipur, Rajasthan and to compare the variations or differences among these two gender groups. The analyses were done in accordance with the method proposed by Cummins and Midlo (1943). The pattern types, total finger ridge count (TFRC) and Absolute Finger ridge count (AFRC) were calculated and analyzed among the entire sample of Bhils. Loop showed the highest frequency in both the sexes (males – 56.9%, females – 63.6%) and whorls found with the frequency of males 35.8% and females – 28.8%. arches were found 7.6% in males and 7.3% in females.

A PRELIMINARY ANTHROPOMETRIC STUDY OF THE RELATIONSHIP BETWEEN DERMATOGLYPHICS AND SICKLE CELL ANAEMIA

Dermatoglyphics have been utilized as models for the diagnosis of vast genetic conditions due to their relationship with the genetic make-up of an individual. However, little studies have been conducted worldwide trying to ascertain the relationship between dermatoglyphics and sickle cell anaemia. Therefore, the present study aimed at generating baseline data to elucidate the possible diagnostic value of dermatoglyphics for earlier detection and screening of Sickle Cell Anaemia (SCA) in Ghana. A total of 400 participants including 200 SCA patients from Komfo Anokye Teaching Hospital and 200 control group (CG) from KNUST were recruited for this study. The palmprints and fingerprints of the participants were taken and the sickling status of the control group was determined. Distribution of the three major fingerprint patterns, PIC patterns, ATD angle and total finger ridge count (TFRC) were determined. Loop dominated in both the SCA and control groups followed by whorl and arch. PIC 300 dominated in the SCA group while PIC 310 dominated in the control group, this was statistically significant. Also, the study recorded 5 unreported PIC’s (PIC 400, PIC 410, PIC 430, PIC 500 and PIC 510) in the Ghanaian population. The SCA group recorded a mean ATD angle of 43.62o while the control group recorded 41.61o, this was statistically significant. The SCA group recorded a mean TFRC of 67.17 while the control group recorded 78.49. The results of the present study have shown that, there is a relationship between dermatoglyphics and SCA and this will serve as a reliable indicator for earlier detection and screening of sickle cell anaemia especially in neonates.

Evaluation of Digital Palmar Dermatoglyphics in Oral Submucous Fibrosis and Leukoplakia: A Prospective Comparative Clinical Study.

To analyze and compare digital dermatoglyphic patterns in patients with oral leukoplakia and oral submucous fibrosis and their role as noninvasive diagnostic tool. Two hundred patients were segregated into four groups of 50 patients each with oral leukoplakia, oral submucous fibrosis, and patients with habits but no lesions were included. They were compared with 50 subjects without habits and without lesions. The study was undertaken to investigate the association of palmar dermatoglyphics with leukoplakia and oral submucous fibrosis. Palm and fingerprints were taken using digital method which were analyzed qualitatively and quantitatively. The present study found increase in frequency of whorls, palmar patterns in I2-I3 area, total finger ridge count, total triradius count and decrease in atd angle with the absence a-b ridge count in patients with oral leukoplakia and OSMF. Thus, with the study of peculiar changes in digital dermatoglyphic patterns in patients with oral leukoplakia and oral submucous fibrosis, early detection and preventive measures can be instituted in normal individuals having habit history without lesions to prevent the occurrence and progression of these potentially malignant disorders.

Exploration of digital dermatoglyphics of two ethnicities of North India- forensic and anthropological aspects

Background and aimThe unique and persistent nature of dermatoglyphic features serves as a valuable tool for the inclusion and exclusion of the suspect at a crime scene. Moreover, dermatoglyphic characteristics have been used to study variations in different population groups and ancestries by researchers. The aim is to enquire whether an individual can be identified as belonging to Rajput or Brahmin ancestry based upon digital dermatoglyphics. Besides, whether the digital dermatoglyphic features can be utilized for the identification of a living or dead. MethodologyThe study was conducted on 512 healthy young adults residing in Districts Shimla and Solan of Himachal Pradesh state of north India. The rolled and plain prints of the finger balls were taken on a specially designed ten fingerprint card. The manual analysis involved identification of the pattern types using Henry's classification. For the analysis, core, triradii, and type lines were marked on the print and further, the ridge counts and indices were calculated. Appropriate statistical tests such as Shapiro-Wilk test, Mann-Whitney U test, Wilcoxon Signed-Rank Test and Simple Correspondence Analysis (CA) were applied to the data for achieving the aim of the study. Results and conclusionThe most commonly occurring patterns are Loops followed by whorls, composites and finally arches in both the ethnic groups. Digit wise frequency is also reported in both the ethnic groups. The overall mean values of Furuhata’s Index, Dankmeijer’s Index, and Pattern Intensity Index are 140.85 and 155.20, 12.44 and 20.49, 13.74 and 13.64 for Rajputs and Brahmins respectively. All the three indices being calculated showed statistically insignificant (p > 0.05) differences for the Rajputs and Brahmins using Mann-Whitney U test Moreover, the Total Finger Ridge count and Absolute Finger Ridge count showed statistically significant bilateral differences (p < 0.05) in Rajputs using the Wilcoxon Signed-Rank test. However, for Brahmins, only TFRC showed statistically significant bilateral differences. The significant association has been observed between the pattern types and finger digits using Correspondence Analysis. It has been concluded that such dermatoglyphic characteristics seem to be confined to ancestry identification, not individual identification. The results highlighting the sex, racial affinity, and bilateral differences may be further useful in the identification of two ancestries.

Palmar Dermatoglyphic: A forecast of hereditary diseases by the cumulative and comparative data in eastern Uttar Pradesh

Background: The study of ridges in the form of different designs as Loops, Whorls and Arches, various triangle, ridge counts as Total finger ridge count (TFRC) and Absolute finger ridge count (AFRC) etc. is called as Dermatoglyphics. Aims &amp; objectives: This study is mainly focused on checking the validity and reliability of Dermatoglyphics for the prediction of various diseases which are mostly inherited like Bronchial Asthma, Essential Hypertension and Diabetes Mellitus. In this study the finger tip pattern like Loops, Whorls and Arches with Finger ridge count (FRC), TFRC and AFRC is included. Material &amp; Method: The Study has been planned in Govt. Medical College, Azamgarh on 190 healthy individual, out of those 140 were male and 50 were female. The finger tip pattern of both hands was collected in the form of Loops, Whorls and Arches with FRC, TFRC and AFRC. The created data was compared with previous case-control study. Results: It is been observed that there is no solid proof of Dermatoglyphic reliability because of unavailability of standard parameters (quality &amp; quantity) of finger tip pattern, wide range of counts of patterns and Matching of present study results with both case and control of previous studies. Some studies was found important in which the count grading (from higher to lower) was changed from most normal results as Loops-Whorls-Arches to significant results as Whorls-Loops-Arches. The variability of results can also put a question on the inheritance of these diseases as it could be environment induced. Conclusion: Our study conclude that Dermatoglyphics should not be used as a tool for prediction of disease because of high variability in results until the cytogenetic study of these inherited diseases doesn’t show any specific parameter range of finger tip patterns in both aspects quality and quantity

Digital and Palmar Dermatoglyphic Patterns of Medical Students of Bingham University, Karu, Nasarawa State Nigeria

Dermatoglyphic traits are genetically determined and most importantly remain constant before birth until death. These traits reflect prenatal developmental stability. Dermatoglyphic features of medical students of Bingham University, Nigeria who are to proceed into clinical classes were studied to know the patterns of dermatoglyphic distributions among the male and female medical students. A total number of Sixty Two (62) medical students comprising twenty seven (27) male and thirty five (35) female students were employed for this study. Finger and palm prints were obtained according to the methods of Cummins using ink. The printink was uniformly smeared on the palmer and finger surfaces to obtain complete print of the finger tips and the palmer surfaces. Dermatoglyphic parameters were analysed with the aid of magnifying lens (X 20), the finger ridge counts (FRC), total finger ridge counts (TFRC), absolute finger ridge counts (AFRC) in male students were significantly higher than in female medical students. However, insignificant differences were noticed in palmer tri-radial angles measured (&lt;ATD, &lt;DAT, &lt;ADT) and other palmer parameters such as a-b ridge counts, a-b distances and the degrees of transversality of the palmer ridges were relatively the same as shown by the main line index. Ulnar loop patterns followed by whorl patterns were found to be dominantly distributed in both male and female medical students, however, ulnar loops and spiral whorls were more prevalent (P&lt;0.05) in male compared with female medical students. Arches were noticed to be distributed more in percentage among the female students. Therefore, in this cross-sectional descriptive study, dermatoglyphic features of presumably normal male and female individuals were found to be of great importance in basic data documentation especially in this part of the Nigeria.

Quantitative dermatoglyphic study of the finger ridge count in breast carcinoma patients from Northeastеrn Bulgaria

The present study aimed to assess the relationship between the results from a quantitative dermatoglyphic analysis of the finger ridge count and the predisposition for developing breast cancer. The fingerprints of 82 breast carcinoma female patients diagnosed by histological and mammographic investigations were obtained and compared to 60 female controls from Northeastеrn Bulgaria. The fingerprints were obtained by classical ink method. The finger ridge count was determined by the method of Cummins and Midlo. The total finger ridge count (TFRC) showed statistically significant difference between the patients and the controls on the first and second finger of the right hand and on the second and third finger of the left hand. Due to statistically significant differences of TFRC on some of the fingers, we discovered differences in the descending formulas in the two observed groups. Descending formulas on the fingers of the breast carcinoma patients compared with the controls on the left hand were respectively 2>4>1>5>3 vs 2>1>4>5>3, and on the right hand 1>2>4>3>5 vs 4>1>3>2>5, respectively. Statistical significance was examined by SPSS 18.0 software. Our data indicated that a dermatoglyphic analysis could be utilized as a fast inexpensive supportive screening tool for the early diagnostics of breast cancer.

Variations in dermatoglyphic patterns in oral submucous fibrosis and leukoplakia patients with and without adverse oral habits

Introduction: The present study was conducted to determine the comparative variations in dermatoglyphic patterns in patients without oral submucous fibrosis (OSMF) and leukoplakia and those having lesions, as well as to predict the occurrence of these diseases and initiate preventive measures in these high-risk patients. Materials and Methods: Dermatoglyphic patterns were collected from randomly selected 120 patients using 3M™ CSD200i. Single-digit Optical Scanner (3M™, Canada, 2015) with automatic capture mechanism was applied to capture finger prints of all the 10 fingers of patients, who were divided in control and test group with respective subgroups of leukoplakia and OSMF. Qualitative analysis of dermatoglyphic patterns in the different groups showed loops, arches, and whorls. Results: The collected data was subjected to analysis using Chi-square test for comparison between the groups; significant difference in P value was observed on comparison between dermatoglyphic patterns in patients with leukoplakia and those with adverse oral habits but without oral lesions (P = 0.00005), patients with OSMF and individuals with adverse oral habits but without oral lesions (P = 0.03), patients with OSMF and individuals without adverse oral habits and without oral lesions (P = 0.004), leukoplakia and OSMF (P = 0.007). Quantitative analysis including total finger ridge count was done by counting the number of ridges in all 10 fingers for all the patients in all the groups. Conclusion: The present study showed weak association in the loop pattern of patients with OSMF than leukoplakia, whorl pattern with adverse oral habits, without oral lesions, and arch pattern with OSMF. More controlled prospective trials are needed to affirm the association, if any, at larger homogeneous Indian sample in future to validate the finding.

Genetic association in chronic periodontitis through dermatoglyphics: An unsolved link?

Introduction: Because dermatoglyphic features are strongly affected by genetic and environmental factors, using it as supportive evidence in the diagnosis of hereditary disorders becomes a reality. Offspring of patients suffering from chronic periodontitis have a high prevalence rate of periodontal breakdown, suggesting strong familial influence. Aims: The present study intends to evaluate and compare the dermatoglyphic patterns in controls and periodontally compromised patients. Settings and Design: A hospital based cross-sectional study was conducted, including a total of 60 individuals, divided into study and control groups of 30 each. The study group included clinically diagnosed periodontitis patients.Materials and Methods: The digital prints were collected using biometric scanner and palmer prints using digital flatbed scanner. Care was taken to ensure that full prints of ridges were obtained. The periodontal status of all 60 participants was assessed clinically for attachment level and pocket depth. Later, Russell's periodontal index was also calculated. Statistical Analysis: The data obtained was subjected to statistical analysis using chi square and Student's t-test. Results: Among the finger ridge patterns, whorl pattern was found to be the most common in the study group whereas loop pattern was the most common in the control group. Mean total finger ridge count in the study group (165.69 ± 25.30) was significantly higher (P = 0.001) than the control group (125.4 ± 16.38). Mean dat angle was significantly higher (P = 0.039) in the study group (60.60 ± 2.76) than the control group (59.20 ± 2.62). Conclusion: Dermatoglyphics may serve as an early predictor in identifying high risk group individuals of developing diseases like periodontitis.
