Relationship among Intercanine width, Intermolar Width and Arch Length in Upper and Lower Arch for Dentistry Students of Thi-Qar University

Author(s): Sameerah Jameel Tarfa* and Nabra F Salih


The arch dimensions are very important and useful to the clinician in all fields of dentistry. In orthodontics, intercanine width, intermolar width, and arch length are all important parameters for diagnostic and treatment planning. The goal of this study was to figure out the link between intercanine width (ICW), intermolar width (IMW), and arch length (VMD) in each upper and lower arch in a class I normal occlusion, as well as the relationship between the upper and lower arches of the same measures. 30 students (15 males and 15 females) with class I normal occlusion (20-22 years old) were chosen from Thi-Qar University/College of Dentistry in Iraq. Intercanine width (ICW), intermolar width (IMW), vertical canine distance (VCD), and vertical molar distance (VMD) were all measured. Spearman's correlation coefficient was used in order to determine the correlation among variables. Intercanine width (ICW), intermolar width (IMW), as well as vertical canine distance (VCD) and vertical molar distance (VMD) of both upper and lower arches, revealed a strong association. Upper intercanine width (UICW) and upper vertical molar distance (UVMD) as well as lower vertical molar distance (LVMD) have a modest association. The lower intercanine width (LICW), on the other hand, exhibited no significant relationships. The relationship between upper and lower vertical molar distances was extremely significant (LVMD).
