The Effects of Virtual Reality on Patients’ Anxiety Before Dental Surgery

Aims: Anxiety due to dental interventions and its complications are common in cases, like wisdom tooth surgery. Related pharmacotherapy is also associated with adverse effects and are not accepted by some patients. Virtual Reality (VR) is one of the new and non-invasive technologies proposed in this regard. This study aimed to determine the effects of VR on patients’ anxiety before dental surgery. Methods & Materials: In this clinical trial, 60 patients who were candidates for dental surgery in Dental School in Mashhad City, Iran, were randomly assigned to two groups of control and intervention (n=30/group). Initially, in addition to demographic characteristics, patients’ anxiety levels were measured using the Spielberger State-Trait Anxiety Inventory (STAI). Then, the intervention group was placed in VR space for 12 minutes using the Remax-RT-V03 audio-visual device; however, no intervention was performed in the control group. Before surgery, anxiety was re-measured by a questionnaire in two groups with the same time interval (15 minutes after the first stage). The obtained data were analyzed in SPSS by Independent Samples t-test, Paired Samples t-test, and Chi-squared test at a significant level of P≤0.05. Findings: The Mean±SD age of the examined patients was 26.5±4.9 years. In total, 53.3% and 46.7% of the study participants were female and male, respectively. The research groups were homogeneous concerning demographic characteristics. The Mean±SD scores of anxiety in the research units before the intervention were 55.56±7.08 in the experimental group and 53.70±10.53 in the control group, i.e., not significantly different. However, after the intervention, anxiety decreased in the experimental group (45.56±10.52), compared to the control group (54.53±9.83); the difference between the study groups was significant (P<0.001). Conclusion: Applying VR was effective in reducing patients’ anxiety before dental surgery; thus, its use in dental clinics is recommended after additional studies.

The aim of this study was to know the effectiveness of the use of alphabet cards game as interesting tool to explain vocabularies and it make it easier to remember their meanings. This study belongs to the quasi experimental research and presents pre-test, post test and to investigate the effect of using alphabet cards game on vocabulary mastery of commercial business administration students. The participants were the students from commercial business administration students at the third semester (N=54) of State Polytechnic Bengkalis and divided into two groups. Both groups were taught vocabulary, however, the experimental group students who are exposed to alphabet cards game and the controlled group students who received conventional method. Pre-test and post-test were given to both experimental group students and controlled group students. The score of the vocabulary tests were compared through independent sample t-test. The mean value of pre-test of experimental class was 61.35, while the control class was 52.23. After learning using alphabet card games in experimental class the mean value obtained in post-test was 78.85, while in control class was 59.04. The improved of learning outcomes can be seen from the level of significance was 0.000 and it was lower than t test 0.000<0.05. It means that the hypothesis null is not accepted. Therefore, it can be concluded that the score of the students in learning vocabulary between the experimental group and control group was significantly different. The experimental group students who learned vocabulary using alphabet cards game had increased their vocabulary mastery.

SUMMARY OBJECTIVE: This study aimed to investigate the effect of virtual reality application on experimental ischemic pain created with a blood pressure instrument in healthy volunteers. METHODS: The research sample consisted of 172 volunteer adult students who conformed to the inclusion criteria. These individuals were assigned into an experimental (n=86) and a control group (n=86) by a simple randomization method. All individuals in the experimental and control groups wereexperimentally subjected to pain for two minutes by applying 260 mmHg of pressure 3-4 cm above the antecubital region of the left arm with an aneroid adult-type blood pressure instrument. During the procedure, the volunteers in the experimental group watched virtual reality images, while those in the control group received no intervention. Immediately after the procedure, the pain levels of the individuals in both groups were assessed with a Visual Analog Scale (VAS). RESULTS: We found that the mean pain score of the individuals in the experimental group was 2.62±1.82, and that of individuals in the control group was 5.75±1.65. Results of the statistical analysis showed a statistically significant difference between the mean pain scores of the individuals in the experimental and control groups (p<0.001). CONCLUSION: This study found that the use of virtual reality was effective in reducing the level of pain in healthy individuals. This method used a smartphone with widespread availability and ease of transportation, which can be used by health professionals as a non-pharmacological method in the management of pain.

Introduction: The most common complications of the nephrotic syndrome (NS) are the frequent relapses, steroid resistance, and long-term steroid administration. Objectives: This study aimed to compare the therapeutic effect of rituximab versus cyclophosphamide in the prevention of relapses and the complications of treatment in children with steroid-resistant NS. Patients and Methods: This clinical trial study was performed on 50 patients with resistant steroidal NS referred to Masoumeh hospital in Qom, Iran. Patients were randomly divided into the two groups including intervention (n=20) and control groups (n=30). In addition to the prednisolone, the intervention group received 375 mg/m2/weekly rituximab intravenously for 4 weeks. The control group received oral doses of cyclophosphamide 2 mg/kg/d for 3 months. During treatment, the frequency of relapses, the mean dose of steroid and the complications of treatment were compared with a paired t-test, independent t-test, and chi-square test. Results: A significant decrease in the mean dose of steroids and the mean number of relapses were seen in patients after administration of rituximab and cyclophosphamide (P<0.001). However, rituximab reduced the dose of steroid administration by 12.25 mg/d, while cyclophosphamide reduced only 2.83 mg/d (P<0.001). Rituximab reduced the relapse rate two times on average, while cyclophosphamide reduced only 0.5 times (P<0.001). The incidence of complications in the cyclophosphamide group was found to be more severe than the rituximab group. Conclusion: To compare rituximab versus cyclophosphamide regarding lower the frequency of recurrence after treatment, we found rituximab is a more suitable drug for the treatment of steroid-resistant NS than cyclophosphamide.

This research was intended to investigate the effect of a culture-based approach in improving students’ reading comprehension on spoof text. For that purpose, a true experimental study was applied to the eleventh-grade students of SMAN 1 Soreang. The sample of this study was 88 students from that school. These students were divided equally into the control and experimental group. The experimental group was given the Culture-Based Approach (CBA) as the treatment in comprehending the text. The students’ scores of pre-test and post-test from both groups were statistically analyzed and compared by the T-test. The findings could be summarized that generally, students from the experimental group gained better achievement than from the control group on their post-test scores. The data analysis also showed that there was a significant difference between the mean score of the pre-test (53.45) and the post-test (58.39.). Furthermore, the result of the t-test (5.707) was relatively higher than the t- table (2.018) for a 0.5 percent level of significance. It indicated that the students’ achievement was significantly improved after the treatment of using a Culture-Based Approach. Thus, it is recommended that a Culture-Based Approach should be considered as an alternative choice for English teachers in teaching spoof text.
