Radiomorphometric Indices and Their Relation to Alveolar Bone Loss in Completely Edentulouspatients: A Prospective Study”

Abstract

Statement of problem:In edentulous patients, alveolar bone loss is a critical factor that affects denture retention, stability, and masticatory function. Purpose: To investigate the influence of age and gender on the mandibular cortical index, panoramic mandibular index, and mandibular cortical width, as well as alveolar bone loss and bone heights in the first premolar and molar region using panoramic radiographs of edentulous patients. Material and methods: Panoramic radiographs of 75 edentulous patients were assessed. In addition to gender and age, the mandibular cortical index, panoramic mandibular index, mandibular cortical width at the mental foramen region, alveolar bone loss, and bone heights of the premolar and molar regions of the mandible were recorded. Statistical comparisons were performed using chi-square and 2-way ANOVA tests. Results: Of the 75 patients, 32 (42%) were men and 43 (57.3%) were women. The association between MCI and age group was not statistically significant in males (P>0.05). In females, the association between MCI and age group was found to be statistically significant (P<0.01). The difference between males and females with respect to mean MCW is found to be statistically significant (P<0.001) indicating that gender is a significant factor influencing MCW. Conclusions:The values of mean cortical width (MCW) at the mental foramen region decreased significantly with age in women (P<0.001). The ratio of the thickness of the mandibular cortex to the distance between the mental foramen and the inferior mandibular cortex (PMI) was not affected by gender or age.Copy Right, IJAR, 2016,.
