A Comparative Study of Dermatoglyphics in Subjects with Hypodivergent and Hyperdivergent Growth Patterns

Correlation of palatal anatomic characteristics with dermatoglyphic heterogeneity in different growth patterns

AIM AND OBJECTIVE

The study aimed to explore the correlation between dermatoglyphic patterns and quantitative palatal anatomic variables in individuals with different growth patterns.

MATERIALS AND METHOD

A cross-sectional study was conducted involving 126 healthy patients aged 17-25 years. Participants were divided into three groups based on growth patterns: average, vertical, and horizontal. Dermatoglyphic patterns were recorded using an optical fingerprint sensor, and palatal characteristics were measured using digital software. Palatal characteristics, including intercanine width, intermolar width, and palatal depth, were measured using digital software. The results were statistically analyzed.

RESULTS

Significant differences were observed in ridge counts among the three growth patterns. The average growth pattern showed lower ridge counts compared to the vertical and horizontal growth patterns. Dermatoglyphic patterns, such as double loops and tented arches, were significantly higher in the horizontal growth pattern. Weak correlations were found between certain dermatoglyphic patterns and palatal characteristics, with simple arch patterns showing a negative correlation with inter-canine width and symmetrical whorl patterns showing a positive correlation with palatal depth. Loop patterns, spiral patterns, double loop patterns, symmetrical whorl, and simple arch patterns were significant predictors of growth patterns.

CONCLUSION

This study revealed distinct dermatoglyphic patterns and ridge counts among individuals with different growth patterns. Weak correlations were observed between dermatoglyphic patterns and palatal characteristics. However, the predictive value of dermatoglyphics for skeletal malocclusion requires further investigation. Understanding the relationships between dermatoglyphic patterns and craniofacial growth can provide valuable insights into genetic and developmental factors affecting dental and orthodontic conditions.

Assessment and Correlation of Dactyloscopy, Cheiloscopy, and Rugoscopy Among Individuals With Different Skeletal Malocclusion—A Cross-Sectional Study

Background and Objectives

A probable association between dermatoglyphics and malocclusions related to skeletal discrepancy may exist as dermal ridges, and craniofacial structures develop from the same embryonic tissues during the same embryonic period. The study aims to assess and correlate the pattern of fingerprints, lip prints, and palatal rugae in individuals with malocclusions related to skeletal discrepancy.

Materials and Methods

The 180 samples collected in the study were divided into 3 groups based on cephalometric analysis into class I, II, and III malocclusion. The fingerprints, lip prints, and palatal rugae patterns were obtained for each participant and pattern analysis was done.

Results

Class I malocclusion with no skeletal discrepancy showed a statistically significant difference in the loop fingerprint patterns on all fingers except the first finger on the right and left hand, branched lip pattern, and straight palatal rugae pattern in primary rugae 1 and 4. Class II malocclusion related to skeletal discrepancy showed a statistically significant difference in the loop pattern on all fingers except in the fourth finger of the right hand which showed a whorl pattern, branched lip pattern, and straight palatal rugae pattern in primary rugae 1, 4, and 5. Class III malocclusion related to skeletal discrepancy showed a statistically significant difference in the loop pattern on all fingers except in the fourth finger of the right hand which showed an absence of arch pattern, vertical lip print pattern, and straight palatal rugae pattern in primary rugae 1.

Conclusion

Dermatoglyphics analysis can be used to indicate developing malocclusions related to skeletal discrepancies. at an early age, thereby aiding the development of treatment aiming to establish favorable occlusion. Prospective and various ethnic and racial-based studies would be valuable for the establishment of dermatoglyphic markers of malocclusion.

Association between dermatoglyphic patterns and growth patterns of subjects with skeletal class I relation: A cross sectional study

Background: To assess the relationship between dermatoglyphic patterns and various growth patterns of the mandible.

Methods: Patients with Class I Skeletal relation were selected after clinical diagnosis followed by digitally tracing the cephalogram. The patients were subdivided into three groups of mandibular divergence patterns ie Average, Horizontal and Vertical. 90 samples ie 30 in each group were selected for the study. The fingerprints of all the selected subjects were then extracted digitally and analysed for the most dominant pattern in each hand.

Results: For the left hand, there was a statistically significant (P<0.05) association between fingerprint pattern and growth pattern when Horizontal growers were compared to Average and Vertical Growers. For the right hand, there was a statistically significant (P<0.05) association between fingerprint pattern and growth pattern when Horizontal growers were compared to Average Growers. A significant association (P<0.05) between fingerprint pattern and growth pattern was also found when average growers were compared to vertical growers.

Conclusions: Horizontal growers had 80% frequency of appearance of whorls in their left hand and 67% in their right hand. Horizontal growers could easily be differentiated from the average and vertical growers because of the dominance of whorl pattern in their hands.

Composite and arch pattern were more frequent in vertical growers when compared to horizontal and average growers.

Reliability of cheiloscopy and dermatoglyphics in hypertension and diabetes. A comparative study

Background

Both dermatoglyphic and cheiloscopic patterns are genetically determined. These patterns are known to be associated with type II diabetes or diabetes mellitus and hypertension which are also considered to have genetic influence due to their familial occurrence. Hence, the aim of this study was to compare reliability of both cheiloscopy and dermatoglyphics with hypertension and type II diabetes.

Materials and Methods

This was a prospective study conducted on 300 study participants. Both cheiloscopic and dermatoglyphic patterns were recorded using validated techniques. Obtained patterns were analyzed and assessed for statistical analysis using the SPSS version 21.0 statistical software. The Chi-square test was used for analyzing the obtained data.

Results

In the present study, no statistical correlation was obtained between either dermatoglyphic or cheiloscopic patterns and type II diabetes or hypertension.

Conclusion

The present study showed that cheiloscopy or dermatoglyphics cannot be used as a predictive tool for assessing a subject's risk of developing type II diabetes or hypertension. These are contradictory findings, thus emphasizing more research in this area so that these noninvasive techniques can be used as predictive tools for developing essential hypertension or type II diabetes.

Dermatoglyphics and Cheiloscopy patterns in hypertensive and type 2 Diabetes mellitus patients: An observational study

Background:

Essential hypertension is a type of hypertension which bears no etiological reasons. It is found to affect approximately 90 to 95 percent of hypertensive individuals. Similarly, type 2 diabetes or diabetes mellitus is a genetically determined systemic condition with a close relation to familial medical history. Both of these conditions or diseases are closely linked with the process of ageing among various other inherited and genetically determined factors. Importantly, a positive family history increases disease risk manifolds. As there is increased risk of hypertension and development of type 2 diabetes in individuals with family history because of genetic factors, the study of co-relation between dermatoglyphics and hypertension can aid in early identification of individuals with a genetic predisposition towards developing hypertension and type 2 diabetes.

Aim:

The aim and objectives were as follows: (1) Analyze dermatoglyphic finger patterns; (2) Analyze cheiloscopic patterns; (3) Comparison of cheiloscopic and dermatoglyphic patterns with hypertension and type 2 diabetes; and (4) to determine if dermatoglyphics and/or cheiloscopic patterns can be used as tool(s) for pre-identification of inherited diseases.

Materials and Methods:

Total 300 study participants age range above 40 years were selected after obtaining informed consent. Lip patterns were recorded using a dark-colored lipstick and a transparent cellophane tape while finger print patterns were recorded using stamp ink-pad and by applying uniform finger pressure on blank paper sheet.

Results and Observations:

Cheiloscopic patterns analysis showed that the branched, straight, intersected, reticular followed by undifferentiated patterns were present in decreasing frequency among male patients while among female patients, branched, intersected, straight and reticular patterns were observed. However, no undifferentiated pattern was observed in female subjects. These findings were consistent with both diabetic as well as hypertensive patients. On the other hand, finger pattern analysis showed that ulnar loop was most frequently observed in both male and female patients with either hypertension or type 2 diabetes. Also, this was followed in decreasing order by arch type pattern, radial loop pattern and whorl pattern in both genders.

Conclusion:

It can be surmised from the study that both the finger prints and lip patterns can be used to ascertain predisposition to type 2 diabetes and hypertension.
