Introduction: The basis of periodontal treatments is the mechanical removal of bacterial biofilm, which is often not sufficient. Therefore, laser therapy can be effective as an adjunct treatment. The aim of the present study was to evaluate the clinical efficacy of the 940-nm diode laser in the treatment of recurrent pockets of patients in the periodontal maintenance phase. Methods: The present clinical trial study was performed on 20 patients. Clinical indices, including bleeding index (BI), probing pocket depth (PPD), and clinical attachment level (CAL) of the studied teeth were recorded before the test. The different quadrants were randomly divided into two experimental (scaling and root planing (SRP)+Laser) and control groups (SRP alone). Both groups were matched in terms of plaque index (PI). Clinical indices were re-recorded using therapeutic methods 30 and 90 days after the treatment, and data analysis was carried out using the t test and LSD. Results: There were no significant differences in PI, PPD, CAL, and BI in both groups before the treatment (P>0.05). However, there were significant differences in PPD, CAL, and BI in the two groups one month after the treatment (P<0.05); it means that improvements were more significant in the experimental group than in the control group. Comparing experimental and control groups, we found that there were no significant differences in PPD and CAL indices three months after the treatment (P>0.05); however, there were significant improvements in the BI index in both groups (P<0.05), so that the improvement was better in the experimental group than the control group. Conclusion: Both SRP+Laser and SRP alone improved clinical indices in patients. In short-term follow-up, the effect of SRP+Laser treatment on BI, CAL, PPD was significantly superior to SRP treatment alone, but in long-term follow-up, SRP+laser was more effective than SRP alone in improving the BI index.

This study examines how piano-accompanied solfège reading practices of preservice music teachers ( N = 28) affect their performance on their musical hearing, reading, and writing (MHRW) classes. A pretest–posttest design with control groups was employed. The data were analyzed by 2 × 2 split-plot analysis of variance (ANOVA) and one-way ANOVA. Consequently, a significant difference was not found between the MHRW performance scores of the experimental and control groups. An analysis of mean performance scores revealed that the scores received by the control group were higher than those of the experimental group after the practice. Follow-up interviews that were held with 14 students after the experimental implementation revealed that students believed piano-accompanied courses were more useful, and they felt more comfortable with piano accompaniment. Although MHRW performance scores indicated that piano-accompanied solfège reading practices did not have a significant effect on preservice music teachers’ MHRW performances, it helped them participate in courses more enthusiastically.

Background There is a known significant risk of negative mental health consequences following traumatic injury, yet no standard approach to prevent psychiatric illness in trauma patients currently exists. Mindfulness-based psychotherapies have been shown to reduce symptoms of post-traumatic stress disorder, depression and anxiety and improve resiliency, however it is unknown whether a mindfulness intervention immediately following traumatic injury would lead to diminished mental health consequences. Methods Multi-system trauma patients at the University of Alberta Hospital (N = 63) and the Foothills Hospital (N = 60) were assigned to the experimental and control groups respectively. Patients in the experimental group were asked to use the guided mindfulness application “Stop, Breathe & Think” for 28 consecutive days. All patients completed the Depression Anxiety Stress Scale (DASS-21) and Connor-Davidson Resilience Scale (CD-RISC) 48 hours and 28 days following admission. An exit interview was conducted for patients in the experimental group. Results There was no significant difference in mean enrollment DASS-21 scores, mean enrollment CD-RISC scores, mean follow-up DASS-21 scores and mean follow-up CD-RISC scores between experimental and control groups. Paired t-tests of mean admission and mean follow-up DASS-21 and CD-RISC scores were not significantly different in the experimental group. Paired t-tests of mean admission and follow-up CD-RISC scores were not significantly different in the control group whereas mean followup DASS-21 scores were decreased in the control group relative to enrolment DASS-21 scores (p = 0.014). Patients reported improved mood after use of mindfulness, and most planned to continue using the therapy and would recommend it to others. Conclusion Our study did not demonstrate an objective benefit of mindfulness intervention immediately following traumatic injury. Exit interview data suggests that a web-based mindfulness intervention may be beneficial for certain trauma patients however further research is required to identify those most likely to realize substantial gains.

The purpose of this study was to compare the levels of Lactobacilli (LB) and Streptococcus mutans (SM) colony forming units (CFU) in the saliva of subjects before and after orthodontic appliance placement.This was a controlled, prospective two-group, two-measurement, clinical trial performed on 64 study patients, 12-15 years old. Subjects in the experimental group were sampled for LB and SM in stimulated saliva collected on the same day but prior to band and bracket placement. The subjects in the control group were sampled on their first screening appointment two months prior to band and bracket placement. The second samples of LB and SM were taken from the experimental and control groups after two months. Saliva was transferred to a selective agar carrier and incubated for 48 hours at 37°C / 99 °F. LB and SM colonies forming units were compared with standard densities.The experimental group wearing orthodontic appliances had significantly higher mean LB CFU counts than the control group at the 2 month follow- up (3.25 vs. 2.57, p =0.0036). The two groups, however, did not show any difference in mean SM CFU counts at the 2 month follow-up (3.0 vs. 3.1, p = 0.66). The results of this study showed that a higher number of CFUs of LB were associated with the group wearing orthodontic appliances after two months and may play a role in the increased levels of plaque seen in many orthodontic patients.

  The aim of this study is to build a group counseling program and investigate its effectiveness to deal with the cultural identity crisis among a sample of adolescents in Dahira Province in the Sultanate of Oman. The researcher applied a scale of the cultural identity crisis designed to suit the purpose of selected sample of the study. This scale was applied on the applicants who participated in the counseling program. They were 60 female adolescents from Fatima bint Qais School for Basic Education, particularly from Post Education classes ( 11th and 12th ). The sample was divided randomly into two groups: the experimental group which consisted of 30 adolescents who received a counseling program which was designed to achieve the objectives of the study. The second group is the control group which equally consisted of 30 adolescents who didn't receive any treatment. The study used the group counseling program based on The Logo Therapy of Frankel (1967). This program consisted of 14 counseling sessions implemented during seven weeks with a maximum of two counseling sessions per week and for about 80 minutes for each session. Arithmetic means and standard deviations for all members of experimental and control group were computed for the cultural identity crisis scale and its five dimensions on the pre, post and follow- up measurements. A T- test analysis was used to examine the statistical significance of the differences in degrees of the cultural identity crisis between members of the experimental and control groups. The results of the study showed significant differences at (0.05≥α) in degrees of crisis between experimental and control groups members in both post and follow- up measurement in favor of the experimental group. This confirms the effectiveness of the group counseling program in reducing significantly the cultural identity crisis within members of experimental group. The results also showed significant differences at (0.05≥α) between members of experimental group in both pre and post measurements in favor of the post measurement. In addition, the result showed no significant differences in the degree of the cultural identity crisis among control group members by using both post and follow- up measurements. This demonstrates clearly the effectiveness of the group counseling program in dealing with the cultural identity crisis with adolescents in Oman. Moreover, the result showed significant differences at (0.05≥α) between the degrees the cultural identity crisis of the experimental group members due to their educational level in favor of the 12th grade.

Background: High mobile-phone dependency may cause cognitive, emotional, and academic impairments among students; hence, proper therapies should be performed to prevent the risk. Objectives: The present study aimed to investigate the effectiveness of the nomophobia therapy package on self-esteem and nomophobia symptoms in high school students. Methods: The research method was quasi-experimental with a pre-test, post-test, and follow-up design and a control group. The statistical population included all the students showing nomophobia symptoms who were in high schools in Isfahan in the academic year of 2018 - 2019. Using purposive sampling, we selected 30 students willing to participate in the project and randomly divided them into experimental (n = 15) and control (n = 15) groups. The research instrument included Nomophobia Questionnaire and Self-Esteem Questionnaire. The experimental group underwent eight sessions (75-minute sessions per week) of nomophobia therapy. The follow-up was performed after two months. Data were analyzed by descriptive and inferential statistics, such as mean, standard deviation, and repeated measures ANOVA. SPSS version 23.0 was further used to analyze the data. Results: The mean ± SD of the post-test scores of self-esteem and nomophobia symptoms were (19.26 ± 3.34) and (50.60 ± 5.07) in the experimental group and (13.46 ± 2.47) and (71.63 ± 8.47) in the control groups. The difference between the scores of the experimental and control groups in the pre-test was not significant (all P-values were > 0.05). Also, the post-test scores did not have a significant difference from the follow-up scores (all P-values were > 0.05). Nomophobia therapy effectively increased self-esteem in students with nomophobia symptoms in the experimental group (P = 0.0001). The training intervention sessions decreased the nomophobia symptoms of high school students in the experimental groups compared to the control group (P = 0.0001). Conclusions: According to research findings, nomophobia therapy was an efficient therapy for improving self-esteem and reducing nomophobia symptoms in students who suffer from the syndrome.

In Bangladesh some researchers have done several studies to find the correlation of simple diffuse goiter with arsenic level but no one conducted any study to find the differences of urinary iodine, urinary arsenic, radioiodine uptake, the thyroid stimulating hormone (TSH) and free thyroxin (FT4) levels between goitrous and non goitrous. That is why, in this research an attempt has been made to compare the urinary iodine, urinary arsenic, radioiodine uptake, TSH and FT4 levels between experimental group with simple diffuse goiter and healthy control group. In this study another purpose has also been made to find the associations between different pairs of variables for both experimental and control group. In this study we have tried to find the impacts of arsenic level on simple diffuse goiter. This is a case-control analytical study. The study is carried out in the Institute of Nuclear Medicine and Ultrasound, in collaboration with the thyroid out patient department of Bangabandhu Sheikh Mujib Medical University. A total of eighty five (85) subjects are included in the study. Among the 85 subjects, a sample of forty five is considered for experimental group with simple diffuse goiter and another sample of forty is considered for healthy control group without any thyroid disease. From the experimental results it has been found that, the arsenic levels, FT4 and radioiodine uptake levels at 2 hours between the experimental and control groups are significantly different but the urinary iodine levels, TSH levels and radioiodine uptake levels at 24 hours between the experimental and control groups are not statistically different. From the experimental results it has also been found that there is significant differentiation between experimental and controls groups in respect of association between different pairs of variables. In this study, another significant finding is that iodine deficiency is not only the factor of causing simple diffuse goiter, but arsenic level is also one of the most important factor of causing simple diffuse goiter.
