Oral Health Literacy and COVID-19 Pandemic Anxiety and Concerns Among Iranian Orthodontic Patients.

OBJECTIVE: This study aims to evaluate the impact of the COVID-19 pandemic on orthodontic appointments, and the concerns and anxiety levels of orthodontic patients in Iran. METHODS: An anonymous 40-question questionnaire was sent online to the patients of private orthodontic clinics in 2 cities of Birjand, and Mashhad, capitals of Eastern provinces of Iran. Orthodontic patients of Mashhad dental school received the questionnaire as well. Descriptive statistics were reported, and the association between gender, oral health literacy (OHL), and adherence to orthodontic appointments and attendance, along with data on feeling, concern, and level of anxiety regarding quarantine/coronavirus pandemic were evaluated using the chi-square analysis. RESULTS: Three hundred twenty-four patients, with a mean age of 32.43 years, answered the questionnaire. Fifty-seven percent of participants said that they only left home for their daily requirements. Seventy-two percent of the participants reported feeling calm about the COVID-19 pandemic and its consequences. Most of the patients (74%) said that they would attend their orthodontic appointment in case of urgency, and 41% of patients declared that their greatest concern was the probability of a delay in completion of treatment. Forty-five percent of patients had adequate OHL. There was a significant association between OHL and willingness to attend orthodontic treatment, concerns regarding the impact of the pandemic on orthodontic treatment, and the frequency of daily teeth brushing. CONCLUSION: Women respected the quarantine more than men. Patients with higher OHL were more willing to attend their appointments, but only in case of an emergency, due to the outbreak of COVID-19. Women were more concerned and had better oral hygiene behaviors.

Evaluation of Divine Proportions in Face and Smile of Patients With Unilateral Cleft Lip and Palate.

INTRODUCTION AND AIM: The facial view of patients with cleft lip and palate greatly affects their psychological well-being and usually leads to introspection. The aim of this study was to compare the face and smile of cleft lip and palate patients and normal population with divine proportion. METHOD: In this retrospective study, 20 female patients (14-25 years) with unilateral cleft lip and palate, who referred to Orthodontic Department of Mashhad School of Dentistry, were selected. The control group consisted of 10 normal female persons with ideal face and normal occlusion. After scanning photographs of full face, profile, and smile views of them, the divine proportions were measured by Photoshop software. Then the data were entered into SPSS software version 22 and analyzed using 2 sample independent t test. P value less than 0.05 were considered as significant. RESULTS: In the study group all proportions were significantly less than the golden proportion. Ls-Rcus/Rch-Rcus and Ls-Lcus/Lch-Lcus had the least difference and Sn-Sm/N-Sn and Sn-Sm/Sm-Me had the most. In the control group, all proportions except Ls-Lcus/Lch-Lcus and Ls-Rcus/Rch-Rcus, were less than the golden proportion. Sn-Sm/N-Sn had the most difference and N-Sn/Sm-Me had the least.Approximately all proportions in cleft patients were significantly different from normal population. Ls-Lcus/Lch-Lcus had the highest difference between study and control group; however, Tr-Sn/Tr-Me in both groups were equal. CONCLUSIONS: The differences between facial indices in cleft lip and palate patients, normal people and golden proportion were significant. As facial proportions of normal people in the authors' study were also different from divine proportions, the authors can conclude that to reach acceptable esthetic results, the authors can approximate patients to normal populations. Unfortunately, the patients with large bone defects, cannot reach to the "esthetic" divine proportion even after reconstructive surgery.

[Effect of Topiramate on Drug Associated Weight Gain of Patients with Schizophrenia and Bipolar I Disorders: A Dose Ranging Randomized Trial]. / Topiramatin Sizofreni ve Iki Uçlu Duygudurum I Bozuklugu Olan Hastalarda Ilaca Bagli Kilo Alimina Etkileri: Doz Ayarlarinin Seçkisiz Klinik Çalismasi.

INTRODUCTION: The aim of this study was to explore the probable prophylactic effects and evaluate different doses of topiramate on body weight in patients treated with olanzapine. MATERIALS AND METHODS: This was a 12 week, double-blind, placebo-controlled clinical trial (Iranian Clinical Trial Registration Code: 201402085280N15) to assess the preventative effects and estimate the optimal dosage of topiramate in drug-induced weight gain. Sixty eight patients aged 18 to 60 that were hospitalized and treated with olanzapine between 2009-2011due to the onset of an acute episode of schizophrenia or a manic episode of bipolar I disorder were selected in Mashhad, the second largest city in the northeast of Iran. Patients were randomly assigned to 4 groups, including 1- placebo; 2- 50 mg/day; 3- 100 mg/day; and 4- 200 mg/day topiramate. Two psychiatrists assigned participants to an intervention group and followed up the treatment process. Raters weighed patients at baseline and also at weeks 1, 2, 4, 6, 8, and 12, respectively. Waist and wrist circumferences were measured at baseline and weeks 4, 8, and 12. Body weight, BMI, wrist, and waist circumference changes were outcome measures of the study. Collected data were analyzed by ANOVA, post hoc Tukey test, Kruskal-Wallis, Mann-Whitney U, and Cohen's d with SPSS version 14. A p-value of less than 0.05 was considered significant. RESULTS: All outcome measures were significantly less than the placebo group compared to the topiramate groups at the end of the fourth week and continued to twelfth week. Nevertheless, there was no statistically significant difference in the measures of any of the topiramate groups with each other at any interval. CONCLUSION: All doses of 50, 100, and 200mg were shown effective in preventing olanzapine-related obesity in schizophrenic and/or bipolar patients.
