“…A study performed by Dutra et al suggested that mean MCW values are higher in men, especially in old age; they observed a significant difference in the mean values of MCW between the genders in patients older than 75 years. 16 In the present study none of the patients were in this age range, and this may be the reason that no gender difference was noted. However, a study of Polish patients aged 20 to 95 years by Kalinowski and Różyło-Kalinowska concluded that MCW is higher in males in all age groups.…”

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.

“…The results in the current study for the mean values of MCW demonstrate an agerelated decrease in women which was in agreement with the results reported by previous studies. 38,44,54 The results by Knezovic Z et al 39 suggested a general decrease of MCW for both genders until the age of 75, when the values begin to decrease sharply for women compared to men. No differences with dental status were assessed.…”

“…In another study by Robert et al 59 there was pattern of decrease in mandibular cortical width in women after the age of 42.5 years and in men there was slow linear decrease in MCW after age of 36 years. Only a few studies 39,44,52 have evaluated the changes in MCW for men. The present study revealed that men showed a stable profile concerning MCW values, irrespective of an increase in age.…”

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,.
