ABSTRACT Thirty per cent of hip fractures occur in men. Nevertheless, the determinants of osteoporosis in men are unclear. Masticatory dysfunction is associated with malnutrition, and might represent an emergent cause of osteoporosis. The aim of this study was to assess the association of bone mineral density and self-assessed masticatory dysfunction in a general older population.
We assessed the association of masticatory dysfunction with standard parameters of bone mineral density (T-score, Z-score and the stiffness index) in all 310 subjects aged 75+ living in Tuscania (Italy).
Among men, self-assessed masticatory dysfunction was associated with T-score [beta=0.86, confidence intervals (CI)=0.15-1.57; p=0.019], Z-score (beta=0.86, CI=0.16-1.56; p=0.017) and the stiffness index (beta=9.12, CI=0.47-17.77; p=0.039) in linear regression modeling, after adjusting. No significant associations were observed in women.
Masticatory dysfunction is independently associated with osteoporosis in elderly men. Evaluation of masticatory function should enter the routine assessment of older men with osteoporosis.

    ABSTRACT: Because of the ageing of populations, disability has become an emergent problem from the clinical, social, and economic perspectives. Nevertheless, the determinants of disability in older subjects are still unclear. We assessed the association between self-assessed masticatory dysfunction (MD) and functional ability in older subjects. We analysed data of all 350 subjects aged 75+ living in Tuscania (Italy). Functional ability was estimated using the Katz' activities of daily living (ADLs), and the Lawton and Brody instrumental activities of daily living (IADLs) scales. MD was reported by 145 (41%) participants. Disability in the ADLs and IADLs was found in 37 (25%) and 53 (37%) of participants with MD, respectively, but only in 11 (5%) and 30 (15%) of the other participants (p<0.001). MD was associated with disability in the ADLs [odds ratio (OR)=2.40, 95% confidence interval (CI)=1.05-5.51], and IADLs (OR=2.77, 95% CI=1.07-7.16) in logistic regression, after adjusting. The association of MD with disability was stronger among subjects aged 80+. MD is independently associated with disability in community-dwelling elderly. Further studies are needed to evaluate the impact of early detection and correction of MD on the preservation of functional status in older populations.

    ABSTRACT: Depression is increasingly recognized in older populations and associated with undernutrition, disability, and increased mortality. Chewing problems (CPs) share with depression these associations. The aim of the study was to evaluate the association, if any, between CPs and depression in older subjects. We assessed 927 participants aged 65 years and older, derived from the 'InCHIANTI' study. Mood was evaluated using the CES-D scale and defined depressed by a CES-D score ≥20. CPs were self-reported. Logistic regression was performed to assess the adjusted association between depression and CPs. The adjusted model was analyzed after stratifying for use of complete, partial dentures and edentulism. Chewing problems were reported by 293/927 (31.6%) participants. Depression was present in 188/927(20.3%) participants. In multivariable logistic regression, CPs were associated with depression (OR = 1.81, 95% CI = 1.26-2.58; p = 0.001). No significant association was found among subjects who used complete dentures (OR = 1.12, 95% CI = 0.80-1.58, p = 0.515). Up to 27.8% of prevalent depression might be attributed to CPs. Chewing problems are associated with depression in elderly population. Use of complete dentures hinder this association. Older depressed subjects should be screened for the presence of CPs; further studies are needed to evaluate the impact of early detection and correction of CPs on the development of depression.

    ABSTRACT: To compare masticatory performance, masticatory efficiency and residual ridge resorption (RRR) in osteoporotic and non-osteoporotic edentulous subjects after rehabilitation with complete dentures. Thirty subjects fulfilling the inclusion criteria were enrolled from the patients visiting the Department of Prosthodontics for complete denture fabrication. Two groups consisting of control subjects (group I; N = 15) and osteoporotic subjects (group II; N = 15) were formed. Complete dentures satisfying certain criteria were fabricated for both groups. Masticatory performance and efficiency were measured 6 months after denture insertion. Areal measurements were taken on lateral cephalograms before and 6 months after denture fabrication. The data were then computed to analyse differences between groups I and II using SPSS statistical software version 15.0. Six months after denture fabrication, the masticatory performance and efficiency were significantly higher (p < 0.001) for group I, with a significant decrease in maxillary and mandibular sagittal area seen in both groups. The rate of bone loss was more in group II compared with group I. Greater masticatory function was demonstrated by the non-osteoporotic group, and the rate of RRR was more in the osteoporotic group compared with the normal group. In this pilot study, osteoporosis leads to greater RRR, decreased masticatory performance and efficiency in edentulous subjects 6 months after denture insertion. Screening for osteoporosis is suggested as a routine procedure for all edentulous subjects undergoing rehabilitation. Recall check-ups for osteoporotic patients should be more frequent, and these patients may require more frequent denture remakes.
