Abstract

Introduction: Dermal ridges and craniofacial structures form from the same embryonic tissues during the same embryonic period. Thus, this might indicate a possible association between dermatoglyphics and facial skeletal disorders, such as malocclusions. Early diagnosis of skeletal malocclusions sometimes can prevent future surgical procedures. The aim of this study was to compare the dermatoglyphic characteristics of different malocclusions.

Methods:  In this cross-sectional study, 323 patients who were referred to Orthodontic Department of Mashhad Dental School were recruited. The participants were classified into three groups according to Angle´s classification, i.e., Skeletal Class 1 (n = 163), Skeletal Class 2 (n = 111), and Skeletal Class 3 (n = 49). For all participants, we recorded the total ridge counts of each finger (TRC), atd angles, a-b ridge counts, and types of fingerprint patterns. Right- and left-hand asymmetry scores were calculated. The chi-squared test was used to compare the dissimilarity of the types of patterns for each finger. Asymmetry of other parameters was analyzed statistically using the ANOVA or Kruskal-Wallis tests. P-values greater than 0.05 were considered to be significant.

Results: A significant difference was determined between Class I and Class III patients in terms of left a-b ridge count (p=0.049). Loop was the most frequent pattern in the three groups, whereas the arch pattern occurred with the lowest frequency. No significant difference was found in the other parameters that were studied.

Conclusion: Although there were some slight differences in dermatoglyphic peculiarities of different skeletal malocclusions, most of the palm and fingerprint characteristics failed to indicate any significant differences.

Volume 12, issue 1, January-March 2020


Next Editorial:

In April-June 2020 issue, the journal will publish an editorial from Morocco (Dr. Benksim, Higher Institute of Nursing Professions and Health Techniques, Morocco). The editorial talks about lessons from COVID-19 pandemic and the Morocco’s success story. The April-June issue is expected to be published by end of June 2020.


 

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.

To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here


 

The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.

The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research. Read more:
