“…The technique for the measurement of the alveolar ridge resorption used was essentially the same as that described by Wical and Swoope. [22]. In a study of Wilding et al, in which the reliability of this technique was tested, it has been concluded that the use of this technique is sufficient to provide information about RRR of mandibular alveolar bone compared to a more complicated method [50].…”

“…The location of the MF relative to the inferior and superior borders of normal mandibles, as expressed by the mean ratio of total bone height to height of the foramen above the inferior border, appears to be consisted enough to justify its use as a reference point in clinical studies. Since the bone below MF constitutes a predictable proportion of the total bone height in the majority of normal subjects, and since this bone is not significantly affected by resorption until extreme atrophy occurs, its height may serve as the basis for estimating the original mandibular height in elderly subjects [22].…”

“…Mandibular RRR was assessed by using the MF and the inferior border of the mandible, as they appear in OPGs, as reference points using Wical and Swoope Analysis method; in which the original height of the mandible is assumed to be 3 times the distance between the inferior border of the mandible to the lower border of the MF [22]. The amount of resorption (R) from the original mandibular alveolar level to the measured level of the residual ridge (L) was expressed as a percentage of the original height of the mandible (Figure 1).…”

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.

Resorption of mandibular alveolar bone following loss of molar teeth and its relationship to age at death in a human skeletal population

Estimating adult age at death in skeletal remains is problematic, particularly in older adults. Molar wear is arguably the most reliable ageing technique for palaeopopulations, but many older adult skeletons have lost their molar teeth ante mortem, precluding its application. Resorption of the alveolar process occurs following tooth loss, and this appears to continue for a prolonged period. The current work investigates the relationship of this process to individual age in a nineteenth century AD European archaeological skeletal series of known age at death (N = 92 individuals), and discusses its potential as an age indicator. Mandibular corpus height was measured at the different molar positions. In females, reduction of corpus height with age was found at molar positions showing ante mortem loss. In both sexes, a relationship was found between age and a simple composite measure of corpus height in the molar region in those showing ante mortem loss of one or more mandibular molars. The correlation was stronger in females (r = -0.74) than in males (r = -0.49), appeared approximately linear, and continued into the ninth decade, the oldest age group in the study material. The results suggest that investigation of height of the posterior part of the mandibular corpus as a skeletal age indicator for individuals that have lost one or more molar teeth is merited in other palaeopopulations.
