The Effect of Partial Edentulism Patterns on Mandibular Radiomorphometric Indices: A Retrospective Radiological Study

Abstract

Objective: To compare mandibular cortical structure among fully dentate individuals and patients with Kennedy Class I/II partial edentulism using the Mandibular Cortical Index (MCI), Mental Index (MI) and Panoramic Mandibular Index (PMI), and to test the dentate/edentulous side difference in Kennedy Class II.Methods: A total of 167 panoramic radiographs (56 fully dentate, 58 Kennedy Class I, 53 Kennedy Class II) were retrospectively evaluated. MCI, MI and PMI were measured bilaterally. Group comparisons used one-way ANOVA/Kruskal-Wallis and Pearson's chi-square test; the paired t-test/Wilcoxon signed-rank test compared dentate and edentulous sides in Kennedy Class II cases.Results: 51.5% of patients were female; mean age was 56.86±15.04 years. Kennedy I and II groups were significantly older than the fully dentate group (p
