Relationship Between Malocclusion and Body Mass Index: A Cross-sectional Study in the Tikrit Dentistry Collage

Abstract

Objective: To determine the effects of obesity and overweight on malocclusion.

Study Design: Cross-sectional study

Place and Duration of Study: This study was conducted at the Tikrit Dentistry Collage from 1st February 2024 to 31st July 2024.

Methods: A total of 103 adults, aged between 19-24 years were part of this study. The following adult subjects were excluded from this work: Subjects who had undergone, previous orthodontic treatment, subject with habits such as atypical swallowing and lip sucking, systemically compromised students, craniofacially abnormal students (clefts and syndromes). Sample was divided into 3 groups based on their body mass index level, G1 normal weight adults, G2 overweight or obese adults and G3 underweight adults.

Results: There was a significant relationship between body mass index and face height. However malocclusion and crowding were not substantially linked with body mass index.

Conclusion: Dietary status may impact craniofacial development and there was no significant link between body mass index and malocclusion or dental crowding.
