Correlation of inter canine width with vertical facial morphology in patients seeking orthodontic treatment

ABSTRACT

It is generally accepted that an important relationship exists between the arch width and vertical facial morphology. The size and form of the dental arches can have considerable implications on or-thodontic diagnosis and treatment planning. The objective of this study was to determine relationship between inter canine width and vertical facial morphology in a sample of patients seeking orthodontic treatment. This cross sectional comparative study was conducted at out patients department of Orthodontics, KRL Hospital, Islamabad from 11-03-2010 to 11-09-2010. 100 subjects were included in the study. 100 lateral cephalometric radiographs and dental casts were obtained, and traced. On lateral cephalograph, SN-MP angle was measured. On dental casts inter-canine widths were measured. When comparison was made between Inter-canine width with SN-MP angle, the p-value for all the results was significant with a p value <0.05. It was concluded from this study that there is a statistically significant relationship between inter canine widths and vertical facial morphology
