“…Authors stated HVID of the eyes can be used to estimate the mesio distal width of the maxillary central incisor tooth. The result of table 3, 4, 5 and 6 is supportive to the previous studies done by Hemalatha et al [12] Jogeswar B, Sangama S evaluated the relationship between the interpupillary distance (IPD) and the combined mesio distal width of maxillary central incisors ( MDW of MCIs) to establish their morpho metric criterion and there significance in two ethnic group of north east India. The mesiodistal width of maxillary central incisors and IPD of all the sample revealed high degree of statistical significance regardless of ethnicity and sex .…”

“…Reliability of digital measurements have been found comparable to manual measurements. [11,12,13] The results of table 1 and 2 is supportive to the previous studies done by Habbu et al [1],Anitha et al [12],Ellakwa et al [14], Sharma et al [15],Al-Kaisy and Garib [16] and Jogeswar et al [17] and contradict to the findings by Wazzan and colleague [18] and Hussain MW et al [19] who found no significant correlation. Hemalatha K, Chander NG, Anitha KV did a study to determine the correlation between the horizontal visible iris diameter (HVID) of the eye and the mesio distal width of the maxillary central incisor tooth in dentate Indian population.…”

Aim - The purposefulness of this study was to establish if a correlation existed between interpupillary distance, corneal diameter, and the width of the maxillary central incisor in selection of teeth .Materials and methods - A total of 120 subjects-60 males and 60 females in the age group 18-26 years were selected based on predetermined selection criteria. On smiling the digital facial image constituting the teeth and the eyes were captured using standardized digital camera. The digital measurements of the interpupillary distance, corneal diameter (medial aperture height, tangential to cornea) and mesiodistal width of maxillary right central incisor in millimeters were analysed using Adobe Photoshop creative cloud software. The data was tabulated , to assess the association between the variables a Karl Pearson’s Coefficient of Correlation was used.Result –Although the Pearson correlation coefficient(PC) was relatively weak (r<0.39) a significant relationship existed between interpupillary distance and (right, left) maxillary central incisor width with p-value <0.01. A negligible positive correlation (r< 0.27) existed between right corneal diameter and (right, left) maxillary central incisor width with p value <0.01. A negligible positive correlation (r< 0.28) existed between left corneal diameter and (right, left) maxillary central incisor width with p value <0.01.Conclusion - The correlations between interpupillary distance, right and left corneal diameter with maxillary central incisor were unable to produce a strong positive statistical association.

“…The latter becomes possible due to the use of various cranial values and their further comparison with human orthodontic indicators [12,14]. Thus, a group of Indian authors [10] found a positive correlation between the size of the human iris and the mesiodistal width of the central incisor of the upper jaw for men and women.…”

Expanding the theoretical knowledge of medical anthropology in the modern field of dental services is one of the main drivers of progress in the orthodontic field. The only way to successfully develop the relationship of these disciplines is to create and fill a database of normative data and search for correlations between various, both obviously related and, at first glance, completely unrelated structures of the human body. The purpose of the study was to determine the features of the relationship between the linear dimensions of molars with the cephalometric parameters of practically healthy men of the first mature age, residents of the western region of Ukraine. Cone-beam computed tomography was performed in 36 practically healthy men of the first mature age, residents of the western region of Ukraine (from Rivne, Volyn, Chernivtsi, Lviv, Ternopil, Khmelnytsky, Ivano-Frankivsk and Zakarpattia regions) followed by odontometry research and cephalometry. Statistical processing of the results was performed in the license package “Statistica 6.1” using non-parametric Spearman’s statistics. As a result of quantitative analysis of reliable and average strength of unreliable correlations of linear computed tomographic sizes of molars with cephalometric indicators and indices of practically healthy men of the western region of Ukraine it is established that the percentage, mainly direct, reliable and average strength of unreliable correlations of linear sizes of molars with cephalometric indices and with indicators of the cerebral or facial skull is almost no different. The largest number of reliable and medium-strength unreliable correlations of linear molars sizes with cranial indices was found with vestibular-lingual and mesio-distal tooth sizes (20.5% with upper molars and 25.0% with lower molars). The highest number of reliable and medium-strength unreliable correlations of linear molars sizes with facial skull indices was found for upper molars with tooth height, crowns and root length (10.8%) and vestibular-lingual and mesio-distal dimensions (12.8%), and for lower molars – only with vestibular-lingual and mesio-distal dimensions (19.4%). The obtained data testify to the prospects of the chosen scientific direction of research, which will further improve the work of physicians in various fields of medicine, including preventive.

“…No intuito de estabelecer uma correlação entre o diâmetro da íris e a medida mésiodistal do incisivo central, Hemalatha et al (2018) avaliaram uma amostra de cem voluntários. Observaram que o diâmetro médio da íris de seus voluntários era de 11,9 mm.…”

“…A íris humana é um diafragma muscular pigmentado situado anteriormente ao cristalino de aproximadamente 12 milímetros de diâmetro em média (Spence, 1991;Hemalatha et al, 2018). Olhos castanho são de caráter dominante em seres humanos Mohr, 1996), e, apesar de mais frequentes entre a população geral, eles apresentam uma pequena faixa no espectro de cores de íris.…”
