Abstract
Background: Mandibular asymmetries are considered morphological variations, which may be imperceptible or linked to malocclusions, temporomandibular disorders, and facial asymmetries. Purpose: To determine the prevalence of mandibular vertical asymmetries through panoramic radiographs of patients treated at the surgical center of the Universidad Central del Ecuador using Habets analysis. Methods: A descriptive and retrospective was conducted to analyze panoramic radiographies of older-than-15-year-old patients who presented complete permanent dentition and were seen within the last 3 years. The sample consisted of 680 radiographs of 309 men and 371 women, with an average age of 22.02 years. Chi-square test was used to analyze the association between asymmetries found for each dependent variable and patients’ age and sex. Mann-Whitney and Kruskal Wallis tests were performed to analyze variable distribution (confidence interval of 95 %. p<0.05). Results: The prevalence of vertical condylar asymmetry was 70.3 %, followed by ramus (38.7 %), and condyle- ramus (30.7 %). There was a larger tendency towards the left side. Conclusion: The Habets asymmetry index with a 3 % cut showed a prevalence of condylar asymmetry to a greater degree, followed by ramus asymmetry and condylar-ramus asymmetry. These values did not show statistical significance regarding age and sex.
