Background:The aim of the present study was to determine the most effective oral hygiene method in fixed orthodontic patients. Methods: A total of 125 patients who had recently started their orthodontic treatment and had not received oral hygiene instructions were randomly assigned to 5 groups (n = 25): verbal instructions (V), verbal instructions plus pamphlet (V + P), verbal instructions plus video film (V + F), verbal instructions plus the use of disclosing agents (V + D), and pamphlet plus the use of disclosing agents (P + D). One week after the installation of orthodontic appliance, plaque index (PI) and gingival index (GI) were recorded and oral hygiene instructions were provided. One week and 4 weeks after oral hygiene instructions, PI and GI were recorded again. Results: PI and GI showed significant decreases in 5 groups after 1 week and 4 weeks (P ˂ 0.05). No statistically significant differences were detected between the 5 study groups in terms of plaque reduction after one week. However, after 4 weeks PI values were significantly lower in V + D group compared to P + D group. Regarding GI, V + D method resulted in a significantly lower GI than P + D after 1 week and 4 weeks. Conclusions: To sum up, all the oral hygiene motivation methods applied in this study can be effective in decreasing PI and GI. However, it appears that the best way is the verbal oral hygiene instruction plus the use of disclosing agents.

Background The purpose of the present study was to evaluate sexual and marital satisfaction in couples with polycystic ovary syndrome (PCOS). A case-control study was conducted on 90 couples with PCOS and 90 healthy couples as a control group. Three measures were used to evaluate sexual function and marital satisfaction: the female sexual function index (FSFI), the Larson sexual satisfaction, and the ENRICH marital satisfaction measures. Results The results of this study show that the mean scores of sexual function, sexual satisfaction, and marital satisfaction were significantly lower in PCOS couples compared with the control group (P < 0.05). Infertility was reported as the strongest predictive factor for sexual function and marital satisfaction in couples with PCOS (P < 0.05). Compared to the control group, sexual and marital satisfaction was lower in patients with PCOS and their partners. Conclusion Since infertility is the strongest predictive factor for the sexual health of couples with PCOS and sexual health is important in family health and marital life, sexual counseling may prove beneficial for these patients.

Recently, there has been great interest in the community over heterogeneous wireless networks in order to support services with high quality. The integration of Wimax and Wi-Fi technologies in communication systems such as Voice ,FTP,Video conducted heterogeneous system and reveal that the proposed network selection technique can effectively decide the optimum network through making trade-offs among network condition, user preference while avoiding frequent handoffs. We identify vertical handover decision algorithm suitable for multimode mobile devices based on the Analytic Hierarchy Process (AHP) and evaluate its performance through simulation by Opnet. This paper gives a comparative analysis of two queuing systems FIFO and WFQ by showing the advantages of using suitable weight which was calculated by AHP. The simulation results show that WFQ technique has a superior quality than FIFO. It could be opportunity to network designers and suppliers are providing the resources to servers more efficient use.
