Wellness is defined as physical, psychological and social well-being, not just the lack of disease and physical handicap. This study aimed at comparing the effects of two intergenerational programs and yoga exercises on the mental health of the elderly. The research was based on a quasi-experimental approach with control group and posttest design. The statistical population consisted of Young and old people living. 175 elders were selected using a randomized cluster sampling method and then randomly assigned to two experimental groups and one control group. Demographic questionnaires, socio-economic status and general health (GHQ-28) were used as research tools. Data were analyzed in two stages before and three months after intervention. The elderly included 95 males, 80 females aged 71.89 ± 8.38 years and 60 youth aged 21.45 ± 0.35 years on mean. The results showed that the intergenerational program and yoga exercises significantly improved scores for mental health and all its subscales. The intergenerational program with a substantial reduction in scores in two sub-scales of social dysfunction and depression had the same effect as yoga exercises. But it had less impact on somatic symptoms and anxiety-sleep disorders. Considering the research findings in confirming the effectiveness of intergenerational programs and yoga exercises on elderly people's mental health, it is suggested that these programs be considered by planners in health and welfare organizations and institutions.

Imprisoned people have usually a poor health status in comparison with the general population. The aim is to exploring. The current study is an applied research and aimed to exploring the relationship between mental health and resilience of 99 women prisoners who participated in recreational sport classes. The data were collected through goldberg's general health questionnaire, with reliability (0.93) and connor-davidson resilience scale with reliability (0.97). Results showed that 59.6% of participants were aged between 20-25 years old and 67.7% of them were between 12 and 36 months in prison. Furthermore, the mental health status of female inmates was as great as possible, but their resilience was insufficient and low. No relation existed between prisoners' age and mental status but was observed a significant correlation between the resilience and age of them. On the other hand, significant difference was noted between mental health status and resilience of female inmates by type of crime, and a negative significant relation was also found between mental health status and resilience due to the amount of conviction. However we didn’t found significant relationship between prisoners' mental health status and resilience in this study but many women prisoners suffer from mental disturbances and physical activity and sport recreational facilities along with psychological and psychiatric care in prisons can be a shortcut to managing these illnesses.

Fluoride is currently accessible in various forms, including water, toothpaste, mouth rinses, and professional fluoride therapy at dental clinics. A body of data supports the use of systemic and topical fluoride from various sources to prevent dental caries. Fluoride ions are absorbed by the enamel before tooth eruption and produce fluorohydroxyapatite, which is more resistant to acid attack than hydroxyapatite crystals [1]. Fluoride ions also aid in the early caries lesion remineralization process. As a result of the two mechanisms outlined above, fluoride strengthens enamel teeth against organic acids and dental caries.
