The relationship among bite force with facial dimensions and dental arches widths in a sample of Iraqi adults with Class I skeletal and dental relations

Abstract

Background: This study aimed to determine whether there is a relationship among the bite force with facialdimensions and dental arches in a sample of Iraqi adults with Class I skeletal and dental relations.Materials and methods: Forty dental students (20 males and 20 females) were selected under certain criteria. Forthose individuals, dental impressions, frontal facial photographs and maximum bite force at molar and incisor regionswere taken. The dental arches widths and facial dimensions were measured using the AutoCAD program 2007, whilethe bite force was determined using special device. Descriptive statistics for the measured variables were performedand gender difference was determined using independent sample t-test, while the relation among bite force andfacial dimensions and dental arches widths was determined by Pearson’s correlation coefficient test.Results: The results indicated that bite force, facial dimensions and dental arches widths were higher in males thanfemales with a non-significant genders difference for the bite force and upper inter-canine width, while with a highsignificant genders difference for the other measurements. Pearson’s correlation coefficient revealed non-significantcorrelation among the bite force and facial dimensions and dental arches widths.Conclusion: This study proved that there was no relationship among the bite force with facial dimensions and dentalarches widths
