“…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.

“…To treat congenital or post-traumatic facial disfigurements in members of these groups successfully, surgeons require access to craniofacial databases based on accurate anthropometric measurements. [7] Photoshop and other computer programs were used by different researchers to obtain measurements from digital photos like Barman J et.al [8] , AL-Kaisy N et.al [9] , Isa ZM et.al [10] but the photos from which the measurements were obtained, were not standardized to obtain the same measurements at different .…”

Clinical facial analysis (CFA) is the method utilized by physicians for evaluating and judging the patient's face, to define its proportions, volume, appearance, symmetry, and visible deformities. It is based on direct examination, clinical photographs, and conventional and computerized X-ray imaging [1]. Clinical facial analysis is essential for many specialists, such as plastic surgeons plastic surgeons, maxillofacial surgeons, otorhinolaryngologists, ophthalmic plastic surgeons, head and neck surgeons, cosmetic surgeons, orthodontists, rehabilitative dentists, and dermatologists, and, generally, for any physicians dealing with facial aesthetics and functions. Clinical facial analysis is not a particular phase of clinical practice or a moment during a patient consultation. It is the largest part of a professional life and a never-ending process. Furthermore, CFA is not separable from everyday activities and we should be able to analyze the face of the patient and, at the same time, answer his or her questions, or illustrate a procedure [1]. Also obtaining accurate measurements is essential for achieving proper diagnosis, putting accurate treatment plans and following up the clinical outcome of the performed procedures.

Aims: To compare the width of the central incisor obtained by the given formulae with the actual width of the central incisor in males and females and assess whether the interpupillary , interalar ,intercommisural and interlateral canthus widths are reliable anthropometric measurements to give an accurate value of the width of the central incisor in local population. Study Design: Original Research. Place and Duration of Study: Department Of Prosthodontics and Crown and Bridge, Dr. D. Y. Patil Dental College and Hospital, Pimpri, Pune. Dr. D. Y. Patil Vidyapeeth, Pune – 411018, between June 2009 and July 2010. Methodology: A total of 160 participants [Males=80; Females=80] were selected in the age group of 18-25 yrs which fulfilled the selection criteria. Informed consent was obtained from each student before participation. The following anthropometric measurements were performed: CW which is the mesiodistal width of the maxillary central incisor, interpupillary width (IPW) and the interalar width (IAW), intercommisural width (ICW) and interlateral canthus width (LCW) which were calculated using a digital vernier calliper. The differences and variables were studied by sex and the differences in the expected mesiodistal width of the central incisor by IPW/CW=6.6 and CW=IAW/4 with the real value was evaluated. The values were evaluated and the differences helped in determining whether these anthropometric measurements can be used as a guide for selection of artificial teeth in males and females in local population. Results: As per this study conducted, in males & females there was statistically significant correlation between the width of the central incisors (CI) and the interalar width IAW (P value =0.043) and the interpupillary width IPW (P value =0.003) when calculated by formula CI=IAW/4 and CI=IPW/6.6. There was no statistically significant correlation between the width of the central incisor and the interlateral canthus width (LCW) and the intercommisural width (ICW). Conclusion: There was significant correlation between the interalar width and interpupillary width and the width of the central incisor. Thus, interalar width, when divided by 4, and the interpupillary width when divided by 6.6 was a reliable predictor of the selection of the maxillary central incisor width in females and males in local population.
