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.

Introduction: Considering that nutrition plays a prominent role in the health of the elderly, oral health and the associated quality of life are very important for a healthy diet. The aim of this study was to investigate the association between the frequency of fruit and vegetable consumption and oral health-related quality of life (OHRQoL) among the elderly in Amirkola. Materials & Methods: This study was part of the second phase of the Amirkola elderly cohort study conducted on 750 older people who underwent a special oral and dental examination in 2016-2020 using the Oral Health Questionnaire. The frequency of fruit and vegetable consumption was assessed with the Semi-Quantitative Food Frequency Questionnaire (SQFFQ), OHRQoL was assessed with the General Oral Health Assessment Index (GOHAI), and information on age, sex, history of systemic diseases, and the number of teeth was extracted from the full data set completed by specialists for each patient. Data were analyzed with SPSS 20 using the chi-square statistical test, ANOVA, and Pearson correlation coefficient. A value of p

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.

Langerhans cell histiocytosis (LCH) is characterized by the congregation of proliferating langerhans cells (LC). Langerhans cells are a part of dendritic cell system of primary immune response that is responsible for presenting antigen to lymphocytes. Being a rare disease, the total incidence of LCH is reported to be 1 in 2 million people. LCH mainly affects children and young adults, with a slight male predilection. LCH is clinically divided into three groups namely Letter-Siwe disease (multiple multi organ affecting LCH at very young age), Hand-Schuler-Christian disease (LCH of bone involvement exophthalmos and diabetes insipidus), and Eosinophilic granuloma (LCH of bone, solitary or multiple). The extent of involvement influences the treatment planning. In this retrospective study, we survey five patients with eosinophilic granuloma in jaws (bony LCH). The diagnosis was confirmed by tissue biopsy and histopathologic examination. Surgery and curettage of the lesions were carried out under general or local anesthesia. After surgery, the patients were examined clinically every 6 month in the first year and then once in a year. The overall outcome was excellent. According to the results, it can be concluded that surgical curettage of localized eosinophilic granuloma is an appropriate and sufficient treatment.

Background: Chronic oral mucosal disease questionnaire (COMDQ) is used to evaluate the quality of life in patients with chronic conditions of the oral mucosa. The aim of the present study was to evaluate the validity and reliability of the Persian version of this questionnaire. Methods: A total of 135 subjects were selected in two groups; group 1 consisted of 95 patients with chronic oral mucosal conditions, including recurrent aphthous stomatitis, oral lichen planus and pemphigus and mucous membrane pemphigoid and group 2 consisted of 40 patients with other oral diseases. The subjects completed the demographic data sheets and COMDQ and then underwent examinations to determine disease severity. After 14 days, the questionnaire was completed again by the group 1subjects only. Results: Cronbach’s α coefficient for COMDQ was estimated at 0.969 and the interclass correlation coefficient was estimated at 0.997. There was a significant relationship between the mean COMDQ scores and disease and pain severity. There was a clear correlation between the patients’ self-report about their general health and mean COMDQ scores and also between their opinions about their oral health and the mean COMDQ scores. Conclusions: The Persian version of COMDQ exhibited proper levels of reliability and validity. It is suggested that this questionnaire be used for the evaluation of the effect of treatment on the oral health-related quality of life (OHQoL).

Background: Recurrent aphthous stomatitis (RAS) is the most common inflammatory ulcerative condition of oral cavity. The aim of this study was to compare the levels of the salivary Malondialdehyde (MDA) and total antioxidant capacity (TAC) and blood parameter in RAS versus healthy controls. Methods: This case-control study consisted of 28 patients with RAS and 28 age and sex -matched control without RAS. Cell blood count was assessed by sysmex system, serum iron and total iron binding capacity was measured by standard laboratory kit and for ferritin ELISA kit was utilized. Salivary TAC and MDA level determined using FRAP and TBARS method respectively. Statistical analysis was performed using SPSS Version 21, chi-square test was used to compare proportions, and student’s t-test and Mann Whitney U-test were used for the comparison of quantitative variables Results: Salivary MDA level was significantly higher (p

Abstract Squamous cell carcinoma (SCC) is the most common malignant tumors of oral cavity. The ratio of men to women is about 2: 1. Generally, it is admitted that 60% of carcinoma of the mandibular gingival are located in the posterior of premolars. Gingiva is one of the less common sites of oral squamous cell carcinoma (OSCC). Due to the variable clinical and behavioral presentations, it can easily be misdiagnosed as benign neoplasms or other inflammatory reactions. We encountered a 76-year-old woman with an unusual OSCC on the anterior mandibular ridge, imitating inflammatory hyperplastic (IH) lesion in May 2013. She complained that her denture was not seated suitably because of a mandibular lesion. After biopsy of the lesion, the surgeon noticed that real bone resorption was not visible in the x-ray image. Then histopathological evaluation detected the OSCC. Patient was referred to the CT-Scan and MRI. Three months later, the lesion recurred, enlarged and extended rapidly and she was emphasized the importance of a secondary surgery in a timely fashion.. She did not accept and then underwent radiotherapy and chemotherapy. In November 2013, the patient passed away because of the progress of OSCC. This case reminded us to keep the possibility of oral SCC in mind while examining every intra-oral lesion.
