Background and purpose: Osteoporosis and periodontitis are two diseases associated with bone loss and are common among postmenopausal women. There are many contradictory results on the effect of osteoporosis on periodontal tissue. This study aimed to determine the association between osteoporosis and periodontal status in postmenopausal women. Materials and methods: This cross-sectional study was part of the second phase of the Amir kola Health and Aging Project (AHAP), in which 210 postmenopausal women were randomly divided into three groups (n=70 per group); normal bone density group, osteopenic group, and osteoporotic group. Periodontal status was measured using Periodontal Disease Index (PDI), Plaque Index (PI), and Simplified Oral Hygiene Index (OHI-S). Bone mineral density (BMD) was measured by Dual-energy X-ray absorptiometry (DEXA). Data were analyzed in SPSS V17 applying ANOVA, Kruskal-Wallis, and Pearson correlation coefficient. Results: The average age of the participants was 65.24±4.36 years. There were no statistically significant differences between the mean OHI (2.26±1.40), PDI (2.76±1.42), and PI (1.23±0.87) in the osteoporotic group, and the mean OHI (2.01±1.62), PDI (2.56±1.61), and PI (1.35±0.91) in the osteopenia group, and mean OHI (1.73±1.37), PDI (2.47±1.43), and PI (1.23±0.87) in the normal group (P>0.05). The OHI, PDI, and PI had a slight but insignificant negative correlation with BMD. Conclusion: According to this study, there is no link between osteoporosis and periodontal status in postmenopausal women.

Background: Hypertension is one of the most common chronic diseases in the world. The prevalence of hypertension in the elderly is increasing. Patients with high blood pressure have to take medication throughout their lives. In this study, the relationship between antihypertensive drugs and oral health-related quality of life in the elderly was evaluated. Methods: This modified cross-sectional study, which is the part of the second phase of the Amirkola Health and Ageing Project (AHAP), was performed on 900 elderly people. Participants included 300 people with hypertension under medical treatment, 300 people with hypertension without medication and 300 people with normal blood pressure. All patients’ blood pressure was recorded, and the standard xerostomia questionnaire and GOHAI questionnaire (Geriatric Oral Health Assessment Index) was completed for all participants. Then, the obtained data were analyzed by SPSS 17, whereby student’s t-test, ANOVA and chi square, Pearson correlation coefficient and logistic regression model were used. A p

Background and purpose: Type 2 diabetes mellitus (T2DM) is the most common form of diabetes, and a metabolic disorder affecting patientschr('39') general health in various ways. The present study aimed to evaluate the oral health-related quality of life (OHRQoL) among older adults of Amirkola, Northern Iran. Materials and Methods: A case-control study was conducted with a sample of 500 elderly people (250 with T2DM and 250 healthy controls) who answered geriatric oral health assessment index (GOHAI) questionnaire and a questionnaire evaluating xerostomia. Then, all participants underwent clinical dental examinations. The obtained data were then analyzed by t-test, chi-square test, and Pearsonchr('39')s correlation coefficient, and p < 0.05 was considered significant. Results: The prevalence of xerostomia was not statistically significant between the T2DM patients and control groups (p < 0.079). Greater number of patients suffering T2DM reported xerostomia according to the records; however, the correlation between this disorder and periodontal disease index (PDI), Plaque index (PI), oral health index-simplified (OHI-S), and geriatric oral health assessment index (GOHAI) in the subjects of the two study groups was not significant (p < 0.0001). Conclusion: In the present study, there was no significant relationship between GOHAI and periodontal indices, demonstrating no difference in the OHRQoL of elderly patients with T2DM and older healthy adults.
