“…These results suggest that in males, the effect of age was cumulative loss, whereas in females a second factor may be involved-namely, the effect of bone loss associated with menopausal cessation of ovarian function. Studies by Ortman et al 79 found a statistically significantly higher percentage of women with severe alveolar ridge resorption than men. Recently, Hirai et al 80 found that the presence of skeletal osteoporosis strongly affects the reduction of the residual ridge in edentulous patients.…”

“…The present study revealed that men showed a stable profile concerning MCW values, irrespective of an increase in age. 37 have shown that the panoramic mandibular index can be used for evaluation of osteoporosis status however, he also suggested that the PMI has no significant advantage over the MCW whereas, Drozdzowska et al 64 concluded that the PMI might be used as an indicator of bone mineral changes when PMI values deviate markedly from the mean.…”

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,.

“…Post menopausal women comprise most of the female edentulous population with severe RRR. The effect of menopause on the mandible was thought to be similar to the effect on the rest of the skeleton and therefore places the post menopausal women at a higher risk of becoming complete denture patients with severe RRR [10,11].…”

Objective: To evaluate the association between type 2 diabetes mellitus and the reduction of mandibular residual ridge in completely edentulous patients wearing complete dentures and to investigate the effect of gender, age and years of edentulousness/ denture wearing on ridge resorption on both groups. Methods: Seventy-two (36 men and 36 women) with a mean age 63.5 years (range of 52 to 73 years) completely edentulous denture-wearing patients were included in this study. Of these, there were 40 patients with type 2 diabetes mellitus and 32 control subjects participated in the study. Resorption in the mandibular residual ridges was assessed by using the mental foramen and the inferior border of the mandible, as they appear in panoramic radiographs, as reference points using Wical and Swoope Analysis method. Measurements were performed using "Dijite" Digital Caliper. The amount of mandibular ridge resorption was calculated and correlated with type 2 diabetes mellitus and the results were compared with control group. Differences in gender, age and years of edentulousness were investigated. Statistical analysis was performed using SPSS (V11.0). A 2-sample t-test was used to evaluate the differences in mean values of mandibular ridge resorption between diabetics and controls. Level of significance was set at 0.05. Results: The mean mandibular residual ridge resorption of all participants is 8.0 mm (26.9%), diabetic group significantly (P < 0.01) had two times more resorption compared with control group (35.8% versus 18.0%). Females recorded greater amount of resorption in diabetics 49.7% versus 21.8% (P < 0.001) and in controls 22.3% versus 13.7%, (P < 0.05) compared to males, respectively. There were no differences in both groups regarding the age of subjects and the length of time they have been edentulous and years of denture wearing. The amount of mandibular residual ridge resorption was directly related to the number of years of edentulousness. Conclusion: Completely edentulous, denture-wearing diabetics, women in particular, are at more risk to have ridge resorption than "nondiabetic" subjects. Reduced mandibular height is directly related to years of edentulousness and denture wearing with greater amount of resorption among diabetics.
