Abstract

Introduction: Arch width is an essential component of dentition and occlusion but it receives little attention during treatment planning. The objective of this study was to evaluate a relationship between intercanine width and sagittal skeletal pattern in orthodontic patients.
Material and Methods: This cross-sectional study was conducted at Orthodontics department, Khyber College of Dentistry, Peshawar, from January to June 2018. After the proposed,study was approved by institutional review board, a total of 150 subjects for the sample were recruited based on convenient sampling technique. Dental casts and lateral cephalograms of patients (75 males and 75 females) between 18 and 23 years of age were evaluated. Intercanine widths including upper intercanine widths (UICW) and lower intercanine widths (LICW) were measured by a digital caliper. Sagittal parameters including SNA and SNB angle were obtained from lateral cephalograms.
Results: The correlation of intercanine width with SNA and SNB angles was evaluated applying Pearson correlation coefficients. According to statistical analysis a significant weak negative correlation of UICW with SNA(-0.254) and SNB angles(-0.209) was present. LICW had significant weak positive correlation with SNA (0.260) and SNB angles(0.293).
Conclusions: It was concluded from this study that there is a statistically significant relationship between intercanine width and sagittal skeletal pattern.
