CORRELATION BETWEEN INNERCANTHAL DISTANCE AND THE MESIODISTAL WIDTH OF THE MAXILLARY CENTRAL INCISORS

NASEER AHMED, MUHAMMAD ABBAS, ASMA NAZ, AFSHEEN MAQSOOD.

Abstract
OBJECTIVE: To establish whether a correlation exists between the innercanthal width and maxillary central incisors.
STUDY DESIGN: A Descriptive cross sectional study
PLACE AND DURATION: Department of Prosthodontics, Dr Ishrat ul Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences Karachi and from 15th October 2012 to 25th March 2014.
METHODOLOGY: One hundred and seventy five dentate individuals with intact maxillary anterior teeth were investigated. The innercanthal space was calculated among the inner canthal angles utilizing computer software. The mean dimension of the two central incisors was determined extra orally at their widest dimension. Teeth measurement and inner canthal distance association in respect to gender was evaluated by paired t test. Pearson correlation coefficients test was premeditated to establish any association amongst innercanthal space and central incisors width, significance was set at a = 0.05.
RESULTS: The mean value for male and female subjects was 33.243.4 mm and 34.903.8 mm correspondingly. The mean width of maxillary central incisors for male and female subjects was recorded 15.84 1.4 mm and 15.921.3 mm. The value (P = 0.000) for both estimations were significant. The Pearson correlation coefficient were positive (r = 0.202) and highly significant (P = 0 .008) between innercanthal dimension and the maxillary central incisors. The results indicated that innercanthal ratio ratio of 1:0.462 may be used to calculate the combined width of maxillary central incisor teeth.
CONCLUSION: Mean of maxillary central incisor width and inner canthal distance were higher in females significantly. The results proposed that innercanthal distance is a good prognostic factor for determining the maxillary central incisors mesiodistal width.

Key words: Innercanthal Distance, Maxillary Central Incisors, Mesiodistal Width, Correlation/Association
