Use of Virtual Reality for the Management of Anxiety and Pain in Dental Treatments: Systematic Review and Meta-Analysis

The Effectiveness of Virtual Reality in Controlling Pain and Anxiety Levels in Four-to-Six-Year-Old Children During Dental Treatment

Background and objective Oral health is critical for children's overall well-being; however, dental anxiety often leads to the avoidance of necessary dental care among children. Virtual reality (VR) has emerged as a successful adjunctive tool in various clinical settings, including pain management. This cohort study explores the use of VR technology in reducing anxiety and pain perception during dental procedures for children. The primary objective of this study was to assess the efficacy of VR distraction in managing pain and anxiety levels in children aged four to six years during dental procedures. Additionally, the study aimed to compare children's anxiety levels with and without VR eyeglasses. Methodology This single-blind, crossover clinical trial was conducted at the Dental Complex of King Faisal University, Al Ahsa, Kingdom of Saudi Arabia. Of the 200 children screened initially, 20 aged four to six years who met the inclusion criteria were selected, and ethical approval for the study was obtained. The study comprised two groups: a control group and an experimental group. Dental procedures were conducted both with and without the use of VR, employing a split-mouth design. Results Our findings provide important insights into the clinical impact of using VR technology to alleviate children's anxiety during dental clinic visits. In our study, we used ANOVA and Tukey's post hoc test to evaluate the effect of VR glasses on vital metrics in children during dental procedures. Our results showed no significant differences before and after using the VR glasses, indicating limited effectiveness in reducing anxiety in this context. Conclusion Based on our findings, we reject the assumption that VR devices are highly effective in diverting children's attention and reducing their anxiety and pain during dental procedures; we recommend further investigations to identify potential confounding factors that could modulate the utility of VR in medical settings.

Effectiveness of virtual reality in reducing preoperative anxiety in adults: A systematic review and meta-analysis

AIM

To evaluate the impact of a virtual reality (VR) intervention on adult patients' preoperative anxiety, heart rate, respiration rate and blood pressure.

DESIGN

A systematic review and meta-analysis of randomized controlled trials (RCTs).

DATA SOURCES

A librarian-designed search of the Cochrane Library, PubMed, Web of Science, EMBASE, CINAHL, CBM, CNKI and Wanfang databases was conducted to identify research studies in English or Chinese on RCTs from their inception to 31 May 2022. Detailed search strategies and the checklist are provieded in Supplementary files S1 and S2.

REVIEW METHODS

Two researchers independently screened eligible studies. The Cochrane Handbook for Systematic Reviews of Interventions was used to assess the risk of bias in the included studies. A fixed- or random-effects meta-analysis model was used to determine the pooled mean difference based on the results of the heterogeneity test.

RESULTS

This study included 11 articles with a total of 892 participants. VR distraction comprised five studies, and VR exposure consisted of six studies. The results indicated that VR could reduce preoperative anxiety in adult patients and VR exposure seems to be more effective. The results also indicated that VR intervention can effectively reduce patients' heart rate and blood pressure compared to traditional intervention methods, but had no significant effect on respiration rate.

CONCLUSION

VR technology could relieve preoperative anxiety in adult patients through distraction or exposure. More well-designed RCTs containing a wider range of surgical types are needed to verify our findings before we can make strong recommendations.

IMPACT

Our systematic review and meta-analysis show a positive effect of VR distraction and exposure interventions in reducing preoperative anxiety in adult patients. We suggest incorporating VR into preoperative procedures as an auxiliary way to reduce negative emotions in eligible patients.

Virtual reality-assisted distraction during transcatheter aortic valve implantation under local anaesthesia: A randomised study

BACKGROUND

A minimal approach, using local anaesthesia alone, has been advocated to promote faster transcatheter aortic valve replacement (TAVR) procedures in intermediate-risk patients. Pre- and periprocedural anxiety and pain remain a concern. Virtual reality (VR) is a form of non-pharmacological distraction that can potentially modulate pain and anxiety. This randomised study explored whether VR reduces pain and anxiety during TAVR without sedation and compared the effects of VR with those of standard care.

METHODS AND RESULTS

Between June 2022 and March 2023, 207 patients underwent transfemoral TAVR (TF-TAVR). Of these, 117 (56.5%) patients were willing to participate in the study and met the educational background and mental status criteria for assessment. Fifty-nine patients underwent TF-TAVR with VR glasses (VR group). Fifty-eight patients underwent standard TF-TAVR without VR (control group; CG). Post-interventional anxiety scores (STAI-S) (31.5 ± 13.4 vs. 38.5 ± 19.2, p = 0.02) and the perceived duration of the procedure (60.1 ± 32.3 vs. 73.0 ± 32.4, p = 0.04) were lower in the VR than in the CG. Procedure time, pain, and anxiety scores (visual analogue scale) were similar between the groups. The complication rate was low and not associated with VR. Post-interventional delirium occurred in nine patients, and was similar between the groups (VR: 4 [6.8%] vs. CG: 5 [8.6%], p = 0.71). No periprocedural strokes were observed.

CONCLUSION

VR for TAVR is feasible and safe and expands the non-drug spectrum of therapy for anxiety and pain in patients undergoing TAVR with a minimalistic approach.

Sensory stimulations potentializing digital therapeutics pain control

For the past two decades, using Digital Therapeutics (DTx) to counter painful symptoms has emerged as a novel pain relief strategy. Several studies report that DTx significantly diminish pain while compensating for the limitations of pharmacological analgesics (e.g., addiction, side effects). Virtual reality (VR) is a major component of the most effective DTx for pain reduction. Notably, various stimuli (e.g., auditory, visual) appear to be frequently associated with VR in DTx. This review aims to compare the hypoalgesic power of specific stimuli with or without a VR environment. First, this review will briefly describe VR technology and known elements related to its hypoalgesic effect. Second, it will non-exhaustively list various stimuli known to have a hypoalgesic effect on pain independent of the immersive environment. Finally, this review will focus on studies that investigate a possible potentialized effect on pain reduction of these stimuli in a VR environment.

Effectiveness of virtual reality distraction interventions to reduce dental anxiety in paediatric patients: A systematic review and meta-analysis

OBJECTIVES

To analyse the effectiveness of virtual reality (VR) distraction intervention for the management of dental anxiety in paediatric patients.

DATA

Randomised controlled trials (RCTs) of VR distraction interventions for reducing anxiety in paediatric patients, published in English were included.

SOURCES

Seven databases, including PubMed, Web of Science, Scopus, MEDLINE via ProQuest, EMBASE, CINAHL and Cochrane Central Register of Controlled Trials, covering the period between January 2000 and September 2022 were searched.

STUDY SELECTION

A total of 12 RCTs involving 818 participants were included. Quality appraisal was undertaken using the Cochrane risk-of-bias tool for randomised trials by two authors independently. Random-effects model was used to summarise the effects of the interventions and pool data.

CONCLUSIONS

Results showed that VR distraction interventions were effective in reducing the dental anxiety of paediatric patients. In meta-analysis, the VR distraction interventions had a significant effect on reducing paediatric patients' anxiety (SMD = -1.74, 95%CI = -2.46, -1.02, p < 0.001, I² = 95%), pain (SMD = -1.57, 95%CI = -2.22, -0.91, p < 0.001, I² = 91%) and heart rate (MD = -10.54, 95%CI = -20.26, -0.81, p = 0.03, I² = 99%) during dental treatment. However, the evidence of VR in managing dental anxiety would become weak because of the publication bias.

CLINICAL SIGNIFICANCE

VR distraction interventions could be an effective approach to alleviate the dental anxiety of paediatric patients. Additional well-designed and high-quality RCTs with larger sample sizes are needed to determine the optimal way to deliver VR interventions in paediatric dental clinics.

Investigate the role of positive and negative memories from dentistry in the anxiety of dental patients in Kerman, Iran

BACKGROUND AND AIM

Several research works show that anxiety is more common in women, low-income classes, and middle-aged and elderly populations. The present study aimed to investigate the role of positive and negative memories in patients' anxiety referred to the dental clinics, offices, and schools of Kerman, Iran, in 2018-2019.

MATERIALS AND METHODS

In this cross-sectional, descriptive, analytical study, the participants were selected among individuals referred to the dental offices, schools, and clinics of Kerman, Iran. In this study, 500 questionnaires were distributed among the participants (based on census method), and of these, 482 of which were reviewed (response rate = 96.4%). The questionnaire used in this study contained four categories of questions, including demographic information, general questions about dentistry, Corah's Dental Anxiety Scale, and Autobiographical Memory Questionnaire. Analysis of variance, t-test, and Chi-square test were used to analyze.

RESULTS

Overall, 281 participants were female, and 201 were male. Based on the findings, dental visits were enjoyable and pleasant experiences for 154 participants, and 165 patients were anxious while the dentist prepared for a restorative treatment. This study showed that people with negative memories had more anxiety. Anxiety was also significantly associated with positive memories, higher education, and gender (female) (P < 0.05). Also, the most negative memories of dental treatments were associated with increased anxiety about dental treatments in adults (P < 0.05), while positive memories did not have a relationship any with decreased anxiety (P > 0.05).

CONCLUSION

The most negative memories of dental treatments were associated with increased anxiety about dental treatments in adults, while positive memories did not have any expected inverse relationship with anxiety.

Effects of Virtual Reality-Based Distraction of Pain, Fear, and Anxiety During Needle-Related Procedures in Children and Adolescents

Background

Needle-related pain, fear, and anxiety can be a deterrent to treatments in children and adolescents. Virtual reality (VR) can be used to manage the poor experience of needle procedures.

Objective

This meta-analysis aimed to examine the effects of VR on pain, fear, and anxiety related to needle procedures in children and adolescents.

Methods

PubMed, EMBASE, and the Cochrane Library were searched for potentially eligible studies published up to June 2021. The outcomes were pain assessed by the Wong-Baker Faces Pain Scale (WBS) or Faces Pain Scale-Revised (FPS-R), and Visual Analog Scale (VAS), fear assessed by Children's Fear Scale (CFS), and anxiety assessed by Children's Anxiety Meter (CAM), VAS, or CFS. Because of expected heterogeneity among studies, all analyses were conducted using the random-effects model.

Results

Ten studies were included (571 children in the VR group and 575 in the control group). Based on the WBS, VR reduced pain, either self-reported (WMD = −2.17, 95%CI: −3.37, −0.97), parent-reported (WMD = −3.52, 95%CI: −4.62, −2.42), nurse-reported (WMD = −3.29, 95%CI: −5.59, −0.99), and physician/investigator-reported (WMD = −3.48, 95%CI: −5.93, −1.04). Using the FPS-R, VR reduced needle-related pain compared with controls (WMD = −0.85, 95%CI: −1.64, −0.06). Similar results were observed for fear (children/adolescents: WMD = −1.52, 95%CI: −2.18, −0.86; parents: WMD = −1.71, 95%CI: −2.30, −1.13; nurses: WMD = −1.55, 95%CI: −2.47, −0.63; physicians/investigators: WMD = −0.59, 95%CI: −1.00, −0.18) and anxiety (self-reported: WMD = −2.79, 95%CI: −4.07, −1.54; parent-reported: WMD = −3.87, 95%CI: −5.58, −2.15; nurse-reported: WMD = −4.64, 95%CI: −6.56, −2.71; physician/investigator-reported: WMD = −2.06, 95%CI: −4.13, −0.00).

Conclusion

A VR-based intervention could reduce needle-related pain, fear, and anxiety in children and adolescents.

The Use of Virtual Reality in Back Pain Rehabilitation: A Systematic Review and Meta-Analysis

This systematic review aimed to synthesize the existing evidence of extended reality (XR) on pain and motor function outcomes in patients with back pain. Following the Cochrane guidelines, relevant articles of any language were selected by 2 independent reviewers from CINAHL, Cochrane, Embase, Medline and Web of Knowledge databases. Of 2,050 unique citations, 24 articles were included in our review. These studies included a total of 900 back pain patients. Despite broader XR search, all interventions were virtual reality (VR) based and involved physical exercises (n = 17, 71%), hippotherapy (n = 4, 17%), motor imagery (n = 1, 4%), distraction (n = 1, 4%), and cognitive-behavior therapy (n = 1, 4%). Sixteen controlled studies were included in a meta-analysis which suggested that VR provides a significant improvement in terms of back pain intensity over control interventions (Mean Difference: -0.67; 95% CI: -1.12 to -0.23; I² = 85%). Almost all included studies presented high risk of bias, highlighting the need to improve methodology in the examination of VR interventions. While the specific set of studies showed high heterogeneity across several methodological factors, a tentative conclusion could be drawn that VR was effective improving back pain intensity and tends to have a positive effect on improving other pain outcomes and motion function. PERSPECTIVE: Extended reality technologies have appeared as interesting nonpharmacological options for the treatment of back pain, with the potential to minimise the need for opioid medications. Our systematic review summarised existing applications of extended reality for back pain and proposed a few recommendations to direct further studies in the field.

Virtual Reality Interventions for Needle-Related Procedural Pain, Fear and Anxiety-A Systematic Review and Meta-Analysis

Needle-related procedures are often a source of pain, anxiety and fear in young patients. This systematic review aimed to investigate the effectiveness of virtual reality (VR) on reducing pain, fear and anxiety in pediatric patients undergoing needle-related procedures. Pain, anxiety, fear, changes in blood pressure and heart rate as well as satisfaction were evaluated as outcomes during needle-related procedures in VR compared with standard care conditions. A meta-analysis was performed, taking into account online databases. Two authors independently conducted literature searches in December 2020. The last search was conducted in March 2021 from a total of 106 records, 7 met our inclusion criteria. One study was excluded from the meta-analysis due to insufficient data. VR was applied as a distractor during venous access. Statistically significant benefits of using VR were shown in children’s pain scores, where VR significantly decreased symptoms (n = 3204 patients, MD = −2.85; 95% CI −3.57, −2.14, for the Wong–Baker Faces Pain Rating Scale and n = 2240 patients, MD = −0.19; 95% CI −0.58, 0.20, for the Faces Pain Scale—Revised). The analysis of fear, anxiety and satisfaction scores revealed no significant differences between the conditions, as the studies were too heterogeneous to be pooled. Distraction using virtual reality may be an effective intervention for reducing pain in children undergoing needle-related medical procedures. However, further research in the implementation of VR as a distractor for children and adolescents is required, due to the limited research into this field.

Virtual Reality in the Assessment, Understanding and Treatment of Mental Health Disorders

Computer scientists usually describe virtual reality (VR) as a set of fancy hardware and software technologies. However, psychology and neuroscience are starting to consider VR as the most advanced form of human-computer interaction allowing individuals to act, communicate and become present in a computer-generated environment. In this view, the feeling of “being there” experienced during a VR experience can become a powerful tool for personal change: it offers a dynamic and social world where individuals can live and share a specific experience. For this reason, the use of VR in mental health shows promise: different researches support its clinical efficacy for conditions including anxiety disorders, stress-related disorders, obesity and eating disorders, pain management, addiction and schizophrenia. However, more research is needed to transform the promises of VR in a real clinical tool for mental health. This Special Issue aims to present the most recent advances in the mental health applications of VR, as well as their implications for future patient care.
