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<0.05 was considered significant. Results: Non-smokers and people with a higher level of education had a better OHRQoL (P=0.022 and P=0.036, respectively). There was no significant relationship between the frequency of fruit and vegetable consumption and OHRQoL, but a significant relationship was found between the frequency of fresh herb consumption and OHRQoL (p=0.005). In men, there was a significant relationship between the number of teeth and frequency of vegetable consumption as well as between OHRQoL and frequency of fresh herb consumption in men (P=0.048, r=0.096).In women, a significant relationship was observed between the frequency of total vegetable consumption and OHRQoL (p=0.021, r=0.129). Conclusion: According to the results of the present study, it was found that the amount of fruit and vegetable consumption has no effect on improving the OHRQoL among the elderly of Amirkola city.

Introduction: Coronavirus disease 2019 (COVID-19) broke out in December 2019 and was declared a pandemic by the World Health Organization in March 2020. The anxiety caused by COVID-19 is extremely critical as it causes delays in dental visits. The aim of this study was to determine dental anxiety during COVID-19. Materials & Methods: This descriptive study was conducted online in February 2022 using a self-designed questionnaire consisting of three sections: questions about dental anxiety, questions about fear of COVID-19, and questions about dental anxiety during COVID-19. The content validity and reliability of the questionnaire were confirmed among the studied subjects. The forms were filled out by all 502 patients. Data were analyzed using SPSS 27. The Chi-square test was used to determine the significance levels of the number of positive responses for each question. A p-value of 0.05 was considered significant. Results: Due to the present pandemic, this study found that patients had a great fear of visiting the dentist because they were afraid that they might contract the disease at the dentist or in a dental office. These results showed that the dentist's explanation of the dental work process was critical in reducing the fear of contracting COVID-19 from the dentist or dental team (p-value < 0.05) and may increase the number of patient visits for dental problems. Conclusion: This study illustrates that people's complaints from COVID-19 and other similar conditions are serious. We must always define how we can better serve patients and protect staff because this disease is not the first pandemic and cannot be the last.

Introduction: The outcome of orthodontic treatment depends on the malocclusion and the ratio of the size of the upper and lower teeth. The aim of this study was to evaluate the discrepancy of tooth crown size in different groups of malocclusions. Materials & Methods: In this cross-sectional study, 165 patients referred to the Orthodontic Department of Babol School of Dentistry were randomly selected. The samples were divided into three skeletal malocclusion groups (55 in each group) according to the ANB angle. The level of anterior and total Bolton ratio in the cases was calculated, and the deviation from normal value of anterior and posterior Bolton was calculated. The results were analyzed using the ANOVA and chi-square test. The significance level was set at p <0.05. Results: The sample consists of 80 males and 85 females aged 12 to 25 years. The mean and standard deviation of the anterior tooth ratio were 79.06 ± 2.87 in Cl I, 79.23 ± 3.18 in Cl II, and 80.16 ± 3.71 in Cl III, and there was no significant difference between the mean anterior ratio between the malocclusion groups. The mean and standard deviation of the total Bolton ratio (TBI) were 91.3 ± 2.39 in Cl I, 91.6 ± 2.49 in Cl II, and 92.49 ± 2.64 in Cl III and the difference between the mean total ratio among the groups was statistically significant. Conclusion: Based on the results of this study between different groups of malocclusion, clinicians should consider the detailed examination of dental proportions in the diagnosis and treatment planning stage.
