Introduction and purpose: Retirement and old age are often interrelated phenomena that happiness and life's satisfaction of elderly decrease Because of social changes such as the loss of job and friends. Considering the role of spirituality in better cognition of life's meaning and adapting to elderly age changes, the aim of this study was to determine the relationship between daily spiritual experience and happiness and life's satisfaction of the retried elderly members of Isfahan retirement center in 2014 Materials and Method: This descriptive-analytic study was done among 190 retired elderly who were referred to Isfahan retirement center and were selected by simple sampling. The information collected via demographic variables, oxford happiness scale and daily spiritual experiences scale. Data analysis by software SPSS 21 and Descriptive Statistical tests, Pearson correlation coefficient, t-test and ANOVA.

Objective: The present study aimed at estimating the case fatality rates of suicide acts in different marital status subgroups and to find interrelation with a population living in Bushehr province along the coastal region of the Persian Gulf coast in southwest of Iran. Method: In this analytical and observational study, suicidal data were gathered in 5 successive years (2008–2012) in the population of Bushehr. Data were extracted from suicide registration forms provided by the Psychiatric Health Unit of Ministry of Health. Questions mainly focused on demographic characteristics, including age, sex, literacy, residency, marital status, birth rank, the number of previous suicide attempts, and probable reasons of suicide, such as family conflicts or/and psychiatric complications. Fatality rates in different subgroups (male/female; married/unmarried; etc.) were compared and odds ratios were computed. The main limitation of this study was the lack of a specific grouping for those who cohabited together (Those who live together and have a sexual relationship without being married). The logistic regression model was used in data analysis. Results: Case mortality rates of suicides were found to be 3.5% for both sexes, 5.2% in males and 2.7% in females. However, among the single population, either divorced or widowed, the probability of death due to suicide was 3.5 times higher (95% CI: 1.5–2.9) as compared to the unmarried. Age as a confounding factor in fatality rates made a significant difference between married and unmarried people, and differences disappeared after adjusting for age. However, fatality rate was still higher in the widowed /divorced group compared to other groups even after adjusting for age. Conclusion: Fatality rate was higher in married people compared to the unmarried, however, after adjusting for age as a determinant factor, no significant difference was observed between the 2 groups. The highest death rate belonged to the age-specific widowed /divorced individuals as compared to all other marital status subgroups.

Background: The present research aimed to assess the effects of oral health intervention programs at school level on students’ oral hygiene in developing countries. To this aim, a systematic review and meta-analysis approach was employed. Methods: The present research was done by surfing electronic databases with MEDLINE Ovid (Embase Ovid, Scopus), Web of Science from 2000 to Mar 2020. The data were collected using a standard type of data collection including specific studies to observational ones, and the data entered RevMan 2014. The eligibility criteria were individually randomized controlled trials (RCTs) or cluster-RCTs including quasi- experimental papers with oral health interventions. The RevMan 2014 package was used for a meta-analysis done through random-effects models. Results: Meta-analyses revealed statistically significant divergences in terms of knowledge (SMD 3.31, 95% CI 2.52 to 4.11; I2 = 98; P<0.001), attitude (SMD 1.99, 95% CI 0. 43 to 3.54; I2 = 99; P<0.001), behavior (SMD 4.74, 95% CI 3.70 to 5.77; I2 = 99; P<0.001), plaque index (SMD -1.01, 95% CI -1.50 to -0. 51; I2 = 97; P<0.001) and Gingival index (SMD 0. 33, 95% CI -0. 36 to 1. 02; I2 = 98; P=0.34) in the case of students who received educational interventions versus those with ordinary care. Conclusion: The present findings attested to the effectiveness of the educational interventions in improving oral health knowledge, attitudes, behaviors, and so on which can presumably contribute to a better oral hygiene, lower incidence of oral diseases, and lower costs of the treatments imposed by oral diseases.

Objective: The present study aimed to assess the morphology of symphysis and alveolar bone thickness (ABT) surrounding mandibular incisors in thalassemic patients, as compared to unaffected individuals. Methods: This case-control study was conducted on lateral cephalograms of 60 thalassemic and 60 unaffected patients with Class II malocclusion seeking orthodontic treatment at Dental School, Shiraz University of Medical Sciences. The sample was divided into three subgroups including hyperdivergent, normodivergent, and hypodivergent, according to the Jarabak index. Symphysis dimensions and alveolar bone thickness surrounding mandibular incisors were measured using AutoCad software. Finally, the correlation between alveolar bone thickness and symphysis morphology was assessed. Results: In general, chin dimensions and bone thickness at different levels of mandibular incisor roots (cervical, middle, apical) were smaller in thalassemic adolescents than controls. Concerning the total sample as well as the normodivergent subgroup, significantly lower values were observed in thalassemic patients for symphysis width, total ABT at the cervical, and lingual ABT at the apical root area compared to controls (p < 0.05). The hypodivergent growth pattern was not associated with any statistical differences between the groups (p> 0.05). In both thalassemic and control subjects, symphysis width showed a weak to moderate positive correlation with ABT of lower incisors (p< 0.05), whereas symphysis height showed a moderate positive correlation with cervical ABT in only ß‐thalassemia patients (p< 0.05). Conclusions: Compared to controls, ß-thalassemia patients showed thinner alveolar bone at different levels of lower incisor roots and smaller symphysis dimensions. There were significant correlations between symphysis dimensions and alveolar bone thickness of mandibular incisors in the sample.
