Figure 1: Facial measurement points Click here to view Morphological facial height (FH) is the distance between nasion and gnathion.Materials and Methods: The research was conducted on 1000 randomly selected subjects of Indo-Aryan North Indian population (563 males and 437 females), aged 1840 years.The parameters were morphological facial height and morphological facial width.The standard, spreading caliper with its scale was used for the measurement of facial parameters.
Canine relationship was observed intra-orally with the subjects seated on the dental chair. Results: Euryprosopic facial type (53.2) was most common in majority of the subjects followed by mesoprosopic (21.6), hypereuryprosopic (19), and leptoprosopic (5.6), and the least common was hyperleptoprosopic (0.6). The canine relation was mostly class I in both the genders, but females showed a higher value of class II and class III canine relations. Conclusion: The overall majority owned the euryprosopic facial type, and there was no significant association between facial morphologic types and canine relationship in both the genders in different age groups at either side. The canine relationship association with facial morphologic type was significant only for the left side. Keywords: Canine relationship, facial height, facial width, morphological facial index. Correlation between morphological facial index and canine relationship in adults An anthropometric study. The prosopic index (PI) classifies individuals into hypereuryprosopic (very broad face), euryprosopic (broad face), mesoprosopic (round face), leptoprosopic (long face), and hyperleptoprosopic (very long face) shapes based upon the ratio of the length of the face to the facial width (FW). Variations in facial types are encountered in every population. Studies indicate ethnic variations in the face type among individuals. Because malocclusion affects a large number of the populations, it is by definition a public health problem. Malocclusion is endemic and wide spread throughout the world; however, it is found widely in different communities, and knowledge of the nature of malocclusion is an essential step in planning orthodontic services on community. Angles classification system was introduced by Edward Angle, an American orthodontist, in 1899. The prevalence of canine asymmetries is also very limited; such information may be more relevant in determining the morphological facial index, because the aim of everyday clinical practice is to achieve a perfect class I canine relationship, with the accompanying molar relationship being a consequence of the extraction alternative. It is widely accepted that maxillary and mandibular canines constitute an integral part of facial and dental esthetics, important for canine guidance, and important for occlusal stability. This study aims in correlating the morphological facial index and Angles canine relationship in adults. Materials and Methods Ethical approval for this study was taken from the Institutional Human Ethics Committee of Saraswati Dental College and Hospital Lucknow (SDCIHEC2013MDS-P18) on 28th November 2013. The study was conducted on 1000 subjects Indo-Aryan North Indian population (563 males and 437 females), aged 1840 years, who were selected randomly. The subjects were asked to sit on a dental chair in a relaxed manner yet with upright position. All measurements were repeated three times, and the mean value of the measurements was taken for further analysis. The measurements were connived with a permissible error of 1 mm. A standard, spreading caliper with scale was used for the measurement of facial parameters. Landmark points used in measuring the parameters were listed as follows Figure 1: N nasion: the midpoint of the nasofrontal suture. Zy zygion: zygomatic prominences, the most lateral point on the zygomatic arch.
