Desirable clinical settings in general dentistry: moving towards the improvement of the educational program.

BACKGROUND: The main task of dental schools is to prepare professional dentists with a high social responsibility. This study provided some practical suggestions from experts regarding desirable clinical settings, in order to establish an infrastructure for practical studies in Endodontics, Periodontics, Oral and Maxillofacial Surgery, Restorative Dentistry, Pediatric Dentistry, Oral and Maxillofacial Medicine, Prosthodontics, Oral Health, and Social Dentistry. METHODS: This research was conducted using a modified Delphi technique in two rounds. The first round involved qualitative content analysis. Participants in interviews were selected purposeful and maximum diversity across the country. To determine the validity and reliability of the data, the four axes proposed by Lichon and Guba were utilized. The second round involved a researcher-made questionnaire, which consisted of 55 questions. This questionnaire was distributed to all dental schools across the country. The validity of the questionnaire were evaluated and by experts and then reviewed. The reliability of the tool was determined to be 0.96 using the alpha coefficient method. RESULTS: The final codes from the interviews of the first round were divided into two categories: settings and educational programs. The final results of research were placed into 2 section: educational settings and instructors, and educational infrastructures. 70% participants agreed to use the college's clinical morning sessions. More than 80% agreed to start up a main clinic with the proposed structure and professors. The use of the hospitalization area also had an agreement of more than 80%. Additionally, community areas such as health service centers, welfare centers, special patient centers, factories, schools, etc. obtained an agreement of over 70%. CONCLUSIONS: The results of this study are presented in the form of suggestions for improving the general dentistry program in relation to educational setting, educators, and educational infrastructures. The common agreement among participants regarding educational settings and their diversity, educational programs, and desired instructors reviewed in the research shows the necessity of reviewing and changing their educational programs in Endodontics, Periodontics, Oral and Maxillofacial Surgery, Restorative Dentistry, Pediatric Dentistry, Oral and Maxillofacial Medicine, Prosthodontics, Oral Health, and Social Dentistry.

Psychometric adequacy of the persian adapted version of the tilburg frailty indicator (P-TFI).

BACKGROUND: Frailty is identified as the primary goal of preventing the various consequences. The present study aimed to assess validity and reliability of the Persian adapted version of the Tilburg frailty indicator (TFI) in Iran. METHOD: This cross-sectional study included three phases of translating the indicator to Persian, assessing the face and content validity, completing the P-TFI by older people, who helped assess the reliability and construct validity. For construct validity, convergent and divergent validity were used. It was expected that the TFI domain scores would show the highest correlations with their related measures of frailty (convergent construct validity) and the lowest correlations with measures of the other domains (divergent construct validity). The study population consisted of 400 older people, selected from six health care centers. RESULTS: The mean age of the participants was 69.05 ± 7.28 years and the majority of the participants were married woman with less than a high school education. The total mean score of TFI was 8.26 ± 1.80, and 42.75% was classified as frail. The test-retest reliability was 0.88 for the total scale, 0.80 for physical, 0.65 for psychological, and 0.81 for social domains. The mean score of frailty and its dimensions (physical, psychological, and social) varied from 4.35 ± 1.78, 1.81 ± 1.33, 1.69 ± 0.73, and 0.86 ± 0.61, respectively. The total score of the TFI was correlated with each alternative measure and the convergent validity was proved. Further, the kappa values ranging from 535 to 0.967 were significant and test- retest reliability for total, physical, psychological, and social dimension were 0.88, 080, 065, and 081, respectively. Further, the convergent or divergent validity is being discussed for clarity. CONCLUSION: The Persian version of the TFI is valid and easy scored tools among Iranian's older people.

Dietary Fiber Intake and Related Factors in Community-Based Iranian's Elderly.

Background: There are considerable documents suggesting that inadequate fiber intake (FI) is a key risk factor for various chronic diseases. The aim of this study was to investigate Dietary FI in the Persian elderly. Methods: This descriptive-analytic study was performed to investigate FI in a sample of the elderly who received free services from healthcare centers in Karaj, Iran. For sampling method: at first, the names of 36 centers were written on small pieces of paper and poured into a container, then another person was asked to randomly select the names of 10 centers, then referring to each of the centers and preparing a list of elderly people, the study subjects were selected, The study was conducted between September 2018, and April 2019Several questionnaires were used to collect data regarding DF: characteristics, daily FI , knowledge, SE (self-efficacy), perceived benefits, and barriers towards FI as well as stage of readiness of FI. t-test and ANOVA were used to compare independent mean values. Data were checked for normality before analysis by using Kolmogorov-Smirnov (K-S) test to check data normality. Results: Totally of 400 elderly individuals entered the study with the average amount of fiber per day. The data analysis indicated they did not know the recommended intake of at least 25 gr each day. feeling less hungry and fiber's price was the most frequent perceived benefits and barriers towards FI , respectively. Gastrointestinal diseases ( P < 0.001), smoking (P < 0.001), and perceived barriers (P < 0.001), were statistically significant independent positive predictors of FI. Conclusion: The findings of the current study indicated that FI among elderly people in Iran was very low and varied a great by gender, education, marital status, income level, employment status, smoking, stage of change, and gastrointestinal disease.

Knowledge and Attitude of Iranian Youth Toward AIDS: A Systematic Review and Meta-Analysis in Iran.

Inadequate knowledge and negative attitudes are the major hindrances to prevent the spread of the human immunodeficiency virus. This study aims to assess the knowledge and attitude toward the human immunodeficiency virus and acquired immune deficiency syndrome among youths in Iran. We conducted a systematic review, searching online databases until July 2018, focusing on knowledge and attitudes about the human immunodeficiency virus and acquired immune deficiency syndrome in Iranian youths. We included the studies that aimed to determine the knowledge and attitudes of people from Iran and were conducted in the last 18 years. In total, 14 eligible papers (out of 300) were entered into the analysis, and the overall knowledge of Iranian youth toward the acquired immune deficiency syndrome was 57.6% (95% CI: 56.7%-58.5%). Also, the results of Cochran's test showed the heterogeneity of the studies (Q=1578.2, df=13, I2=79.4%, p<0.001). We concluded that our results would guide the development of population-focused knowledge and attitude about the human immunodeficiency virus and acquired immune deficiency syndrome in Iran, which is lacking among the general public and healthcare staff.

The Relationship between Anger Expression and Its Indices and Oral Lichen Planus.

Oral lichen planus (OLP) is a common inflammatory disease with unknown etiology. Depression, stress and anxiety are psychological factors that their influence on the expression of lichen planus by affecting the immune system's function has been confirmed. There is a probable relationship between anger and OLP expression. Therefore, the present study aimed to evaluate the association of "anger" and OLP. In this descriptive study 95 subjects were included in 3 groups. A: patients with oral lichen planus, B: positive control, C: negative control. Anger and its indices were assessed by the State-Trait Anger Expression Inventory-2 (STAXI-2) questionnaire, and pain was measured via the Visual Analogue Scale (VAS). The collected data were analyzed statistically using SPSS 18 software. The lichen planus and positive control groups bore higher total anger index (AX index) values compared with the negative control. Comparing anger expression-in (AXI) among the lichen planus and negative control groups revealed higher grades in lichen planus group. Evaluating the pain severity index (VAS) data and anger indices in lichen planus group, Spearman's Rank Correlation Test revealed a significant correlation between TAngR (reactional anger traits) and pain severity. The findings of this study indicated that there was a significant correlation between anger control and suppression of lichen planus development. On the other hand, the patients with more severe pain mostly expressed their anger physically. Based on the findings, we can make the claim that anger suppression and its control-in (gathering tension) may play a role in the development of lichen planus as a known psychosomatic disorders.

Evaluation of the Relationship between Serum Lipid Profile andOral Lichen Planus.

Background and aims. Oral lichen planus (OLP) is an immunologic disorder. A large number of studies have reported that lipid rafts have a key role in receptor signaling of lymphocytes. Here, we explore the potential of lipid rafts as targets for the development of a new class of agents to down-modulate immune responses and treat autoimmune diseases. Materials and methods. The present cross-sectional study evaluated 88 patients referring to the Department of Oral Medicine in 3 groups (Group 1: erosive OLP; Group 2: non-erosive OLP; Group 3: healthy). A total of 3 mL of blood sample was taken from each subject and the serum levels of cholesterol, triglycerides, HDL and LDL were determined. The mean outcomes of each group were compared with each other and analyzed two by two. Results. The results of statistical analyses showed no significant differences in mean HDL and LDL serum levels between the three groups. The results of post hoc LSD test showed that mean serum levels of subjects with erosive and non-erosive lichen planus were higher than those in healthy subjects. In relation to triglyceride serum levels, the mean serum levels of triglycerides were higher in erosive and non-erosive OLP patients compared to healthy subjects. Conclusion. Triglyceride and cholesterol can be considered to have a critical role in the incidence of lichen planus and in its manifestations as predisposing factors.
