Background: The theory of mind acts as an umbrella which covers the perception of children of others’ mental conditions under its banner and paves the way for child’s social cognition. This study was designed to compare the effects of different variables such as intelligence quotient (IQ), sex, age, and mental maintenance on the theory of mind development levels in autistic and normal children. Materials and Methods: In this case-control study, 19 autistic and 19 normal children were selected based on the in-reach sampling procedure and were also matched by age. The participants completed Wechksler intelligence scale for children, Stimman theory of mind task, and mental maintenance task. Results: In comparison to normal children, autistic children showed a clear deficiency in their theory of mind development levels however, age did not have a significant effect in this regard. Conversely, IQ and sex had significant impacts on the development of theory of mind. In addition, mental maintenance, alone, had a significant effect on the theory of mind. Conclusion: Noticing the existence of some primary levels of theory of mind in autistic children, some aspects of theory of mind can be compensated for through the provision of basic instructions and guidelines for development of intellectual and cognitive abilities in early childhood and primary stages of diagnosis.

Background & Aim: Infertility is defined as inability to become pregnant with regular sexual intercourse for more than one year without using preventive methods. Infertility has negative effects on the quality of life of infertile couples. this thesis was done with the purpose of investigating the effecte of infertility counseling to improve the quality of life among infertile couples
Materials and Methods: This randomized clinical trial was carried out on sixty infertile couples with primary infertility in2017. Samples were allocated to an intervention (30 couples) and a control group (30 couples) by simple randomization. Even days of the first week, the intervention group and in the odd days, control group samples were selected, and the opposite was done in the following week. The intervention group received infertility counseling for six forty-five-minute sessions twice a week. However, control group received routine care. FertiQoL questionnaire was completed before and after intervention. For data analysis SPSS 19 software and Paired T-Test statistical tests , Mann-Whitney and Chi-Square Test, were used.
Ethical Considerations: Ethical code is IR.KMU.REC.1395.678  in Kerman University of Medical Sciences
Findings: Comparison of the differences between the mean of quality of life in the intervention and control groups before counseling and after counseling indicated  that infertility counseling increased Meaningful quality of life in the intervention group (p <0.0001) 
Conclusion: The results indicated infertility counseling can improve the quality of life among infertile couples. Therefore, it can lead to more satisfaction and cooperation in infertility treatment.

Background and Aim: Different implant angulation, which is unavoidable in clinical situations, can affect the accuracy of impression. The aim of this study was to investigate the effect of fixture position on the accuracy of connecting impression coping to implants with internal hex.
Materials and Methods: A gypsum model with 4 implants with internal hex connection was prepared. The implants were installed in different mesiodistal angles of 0, 15, 25 and 35 degrees to the longitudinal axis in the gypsum model. To simulate the gums, a gingival mask was injected around the implants to a height of 2 mm. After a training session for senior dental students on how to close the impression coping, forty students were asked to close the impression copings on four implants. The correctness of the impression coping was evaluated by an expert prosthodontist. Data were statistically analyzed using Cochran Q test. Significance level was considered 0.05.
Ethical Considerations: this article is approved by ethics committee of Arak University of Medical Sciences.
Findings: The correct performance of students in connecting the impression coping to the implant at angles of 0, 15, 25 and 35 degrees was equal to 85%, 72%, 52%, 35%, respectively. With the exception of 0 and 15 degree groups, a statistically significant difference was observed between different study groups.
Conclusion: The fixture position has a significant effect on the accuracy of connecting impression coping to the implants with the internal hex and by increasing the implant angulation, the accurate connection the impression coping to the implant decreases.
