Estimation of Innercanthal Distance(ICD) of An Individual Using The Incisal width of Maxillary Central Incisor -A Pilot Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 9
Abstract
Introduction: Dental evidence is a valuable tool in identifying inividuals. This study is based on the fact that the ICD is attained by the age of 1 year, after which the growth in this area is slow in contrast to outer orbital dimension. Objectives: To ascertain whether the incisal width of the maxillary central incisor can be used to detect the inner canthal distance. To derive at an equation ICD=CIWX2/0.618 from the previously proven FORMULA CCIW=ICDX0.618/2. This study attempts to emphasize the practicality of applying Inner-canthal Distance as an adjuvant to support and aid in sketching of an individual. Materials and Methods: 30 subjects between 18 and 35 years of age, free from facial and dental deformities were examined; Inner Canthal Distance (ICD) and Incisal width of Central Incisor measured from Wax bite (IWWB) were recorded and ICD was calculated using the formula ICD=CIWX2/0.618. Pearson’s Correlation Coefficient test was used to evaluate the ICD and the IWWB. Results: The ICD and Incisal width of Central Incisor measured from Wax bite was found to be highly correlated (r=0.54). Conclusion: Based on these results we propose the use of incisal width of maxillary central incisor to calculate the ICD and vice-versa as, to supplement the evidence provided for individual identification/sketch and increase its value as a forensic tool.
