Review
Hypnosis has proven a powerful method in indications such as pain control and anxiety reduction. As recently discussed, it has been yielding increased attention from medical/dental perspectives. This systematic review (PROSPERO-registration-ID-CRD42021259187) aimed to critically evaluate and discuss functional changes in brain activity using hypnosis by means of different imaging techniques. Randomized controlled trials, cohort, comparative, cross-sectional, evaluation and validation studies from three databases-Cochrane, Embase and Medline via PubMed from January 1979 to August 2021-were reviewed using an ad hoc prepared search string and following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. A total of 10,404 articles were identified, 1194 duplicates were removed and 9190 papers were discarded after consulting article titles/abstracts. Ultimately, 20 papers were assessed for eligibility, and 20 papers were included after a hand search ( = 40). Despite a broad heterogenicity of included studies, evidence of functional changes in brain activity using hypnosis was identified. Electromyography (EMG) startle amplitudes result in greater activity in the frontal brain area; amplitudes using Somatosensory Event-Related Potentials (SERPs) showed similar results. Electroencephalography (EEG) oscillations of θ activity are positively associated with response to hypnosis. EEG results showed greater amplitudes for highly hypnotizable subjects over the left hemisphere. Less activity during hypnosis was observed in the insula and anterior cingulate cortex (ACC).

Review
BACKGROUND
Ketamine has been used as a safe and effective sedative to treat adults and children exhibiting high levels of anxiety or fear during dental treatment. Pediatric dentistry often involves patients with high levels of anxiety and fear and possibly few positive dental experiences. Patient management can involve behavioral approaches, as well as the use of sedation or general anesthesia with a variety of agents, including midazolam, diazepam, hydroxyzine, meperidine, and ketamine. The aim of this study was to investigate the clinical efficacy of ketamine use in pediatric sedation dentistry through systematic review and analysis.
METHODS
A systematic review of publications between 1990 and 2015 was conducted using PubMed and MEDLINE databases maintained by the US National Library of Medicine and the National Institutes of Health. The keywords used were (ketamine) AND (dental OR dentistry) AND (sedation). The abstract and title of all potential publications were then screened for clinical trials and to remove non-English articles, non-human or animal trials, and other non-dental or non-relevant studies.
RESULTS
A total of 1,657 citations were initially identified, reviewed, and screened, eventually resulting in inclusion of 25 clinical trials in this systematic review. Nineteen studies evaluated ketamine effects in pediatric dental sedation using oral (non-invasive) administration, three involved subcutaneous or intramuscular injection, and three were completed intravenously. Evidence analysis of these trials revealed the majority (n = 22/25) provided strong, positive evidence for the use of ketamine (alone or in combination) to reduce dental anxiety and behavioral non-compliance with the remainder suggesting equivocal results. Additional endpoints evaluated in some studies involved dosage, as well as time to achieve sedation effect.
CONCLUSION
The use of ketamine (alone or in combination) can provide safe, effective, and timely sedation in pediatric patients regardless of the route of administration.

Review
BACKGROUND
Despite the increasing concern, the literature lacks a comprehensive synthesis of the prevalence of depression, anxiety, and sleep disturbances among dental students.
METHODS
We conducted a systematic review following Cochrane Manual for Systematic Reviews of Interventions and PRISMA guidelines. Our search, spanning databases like Medline, Web of Science, and Scopus, covered data until June 5, 2023. A random effect model was utilized for the meta-analysis.
RESULTS
From 508 initially identified articles, 45 studies met eligibility criteria. The pooled prevalence of depression, anxiety, and sleep disorders among dental students was estimated as follows: depression [38%, 95% confidence interval (CI): 32%-44%; I = 98%], anxiety [48%, 95% CI: 41%-55%; I = 97.7%], and sleep disorders [31%, 95% CI: 24%-38%; I = 85.7%]. Subgroup analyses based on geographical regions and assessment scales revealed significant between-subgroup differences. Meta-regression identified associations between the prevalence of depression and the year of publication and between the prevalence of anxiety and total sample size, participant age, and year of publication. Publication bias assessments demonstrated a lack of significant bias, strengthening the validity of the findings.
CONCLUSIONS
The prevalence of depression, anxiety, and sleep disturbances in dental students is significant. This study highlighted the need for targeted interventions and support systems within dental education to alleviate the mental health challenges students face, ultimately ensuring their well-being and competence as future healthcare providers. Further research should explore the effectiveness of interventions in this population.

Meta-Analysis Review
Demand for dental implants has increased in recent years and the use of conscious sedation for this type of surgery can be of great benefit. Therefore, the aim of this systematic review was to evaluate the scientific literature related to the effect of conscious sedation on the reduction of anxiety, and patient and surgeon satisfaction. The Embase, PubMed, ProQuest, Scopus, Ovid, and Cochrane databases were searched without limitations. According to the inclusion and exclusion criteria determined for the study, 10 articles were selected for the final review during several screening stages. These studies were reviewed in their full-text form by the research team and the intended data was extracted. The risk of bias was assessed for each of the selected articles. Five studies were ultimately included. Two of the them compared local anesthesia and conscious sedation, while another 2 compared the consequences of different types of conscious sedation. The anxiety reduction and patient and surgeon satisfaction data was collated. Midazolam was the most frequently used agent. After a thorough review of the final articles extracted based on the study protocol, it was concluded that the use of conscious sedation during implant surgery reduces patient anxiety, and also increases the satisfaction of the patient and surgeon.

Review
BACKGROUND
The presence of parents during the dental appointment can affect the child's behaviour and, consequently, the success of the treatment.
AIM
This systematic review aimed to evaluate whether parents' presence in the operatory room influences children's behaviour, anxiety and fear during dental treatment.
DESIGN
EMBASE, Cochrane Library, LILACS, PubMed, PsycINFO, Scopus, Web of Science, Google Scholar, OpenGrey and ProQuest Dissertations and Theses Databases were searched. Randomized and non-randomized clinical trials in which some measure assessing children's behaviour and/or anxiety and fear during dental treatment with the presence and absence of parents were included. Two reviewers assessed studies for selection, extracted data, evaluated bias (Joanna Briggs Institute) and graded the certainty of evidence (Grading of Recommendations, Assessment, Development and Evaluation). Random-effects meta-analyses using mean difference (MD) and narrative synthesis were performed.
RESULTS
A total of 2846 papers were identified, and after a 2-phase selection, sixteen studies were included (five in meta-analyses). There was no difference in children's behaviour in the presence or absence of parents (P = .23, P = .40, P = .60 and P = .89, respectively). The presence or absence of parents did not influence children's anxiety (P = .94 and P = .97) or fear (DM: -0.08; CI:-0.34-0.19, P = .24). All included studies presented a high risk of bias, and the certainty of evidence was considered to be very low.
CONCLUSION
It is concluded that parents' presence in the operation room does not influence children's (up to 12 years old) behaviour, anxiety and fear during dental treatment with very low certainty of evidence. Methodological limitations of included studies, however, suggest that better designed trials are needed to adequately understand this issue.

Review
INTRODUCTION
Bones are frequent sites of metastatic disease, observed in 30-75% of advanced cancer patients. Quality of life (QoL) is an important endpoint in studies evaluating the treatments of bone metastases (BM), and many patient-reported outcome tools are available. The primary objective of this systematic review was to compile a list of QoL issues relevant to BM and its interventions. The secondary objective was to identify common tools used to assess QoL in patients with BM, and the QoL issues they fail to address.
METHODS
A search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases between 1946 and 27 January 2023 with the keywords "bone metastases", "quality of life", and "patient reported outcomes". Specific QoL issues in original research studies and the QoL tools used were extracted.
RESULTS
The review identified the QoL issues most prevalent to BM in the literature. Physical and functional issues observed in patients included pain, interference with ambulation and daily activities, and fatigue. Psychological symptoms, such as helplessness, depression, and anxiety were also common. These issues interfered with patients' relationships and social activities. Items not mentioned in existing QoL tools were related to newer treatments of BM, such as pain flare, flu-like symptoms, and jaw pain due to osteonecrosis.
CONCLUSIONS
This systematic review highlights that QoL issues for patients with BM have expanded over time due to advances in BM-directed treatments. If they are relevant, additional treatment-related QoL issues identified need to be validated prospectively by patients and added to current assessment tools.

BACKGROUND
Oral benzodiazepines (BZDs) are useful tools for periprocedural anxiolysis. The United States Food and Drug Administration (FDA) recently issued a black-box warning of their risks of abuse and dependence. We performed a systematic review evaluating the safety and efficacy of oral BZDs for periprocedural anxiolysis in outpatient dermatologic, plastic surgery, dental, and ophthalmologic procedures performed under local anesthesia.
METHODS
A systematic review of 5 databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Oral benzodiazepine safety and efficacy data were extracted from eligible articles.
RESULTS
A total of 43 articles and 4,060 subjects were included. Oral BZDs consistently imparted a positive anxiolytic effect and demonstrated superior or equivalent scores in patient satisfaction, surgeon satisfaction, pain, and anxiety to comparator groups in most studies. Thirty-five subjects experienced transient hypoxia, and 2 experienced transient hypertension. A total of 195 mild, self-limited adverse effects were reported. None of the studies addressed the risks of abuse and dependence in this clinical setting.
CONCLUSION
Short-term use of oral BZDs for periprocedural anxiolysis seems to be safe and effective. The 2020 FDA black-box warning should not deter their appropriate use in dermatologic surgery and other low-risk outpatient procedures.

Meta-Analysis Review
BACKGROUND
Midazolam is used for sedation before diagnostic and therapeutic medical procedures. It is an imidazole benzodiazepine that has depressant effects on the central nervous system (CNS) with rapid onset of action and few adverse effects. The drug can be administered by several routes including oral, intravenous, intranasal and intramuscular.
OBJECTIVES
To determine the evidence on the effectiveness of midazolam for sedation when administered before a procedure (diagnostic or therapeutic).
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL to January 2016), MEDLINE in Ovid (1966 to January 2016) and Ovid EMBASE (1980 to January 2016). We imposed no language restrictions.
SELECTION CRITERIA
Randomized controlled trials in which midazolam, administered to participants of any age, by any route, at any dose or any time before any procedure (apart from dental procedures), was compared with placebo or other medications including sedatives and analgesics.
DATA COLLECTION AND ANALYSIS
Two authors extracted data and assessed risk of bias for each included study. We performed a separate analysis for each different drug comparison.
MAIN RESULTS
We included 30 trials (2319 participants) of midazolam for gastrointestinal endoscopy (16 trials), bronchoscopy (3), diagnostic imaging (5), cardioversion (1), minor plastic surgery (1), lumbar puncture (1), suturing (2) and Kirschner wire removal (1). Comparisons were: intravenous diazepam (14), placebo (5) etomidate (1) fentanyl (1), flunitrazepam (1) and propofol (1); oral chloral hydrate (4), diazepam (2), diazepam and clonidine (1); ketamine (1) and placebo (3); and intranasal placebo (2). There was a high risk of bias due to inadequate reporting about randomization (75% of trials). Effect estimates were imprecise due to small sample sizes. None of the trials reported on allergic or anaphylactoid reactions. Intravenous midazolam versus diazepam (14 trials; 1069 participants)There was no difference in anxiety (risk ratio (RR) 0.80, 95% confidence interval (CI) 0.39 to 1.62; 175 participants; 2 trials) or discomfort/pain (RR 0.60, 95% CI 0.24 to 1.49; 415 participants; 5 trials; I² = 67%). Midazolam produced greater anterograde amnesia (RR 0.45; 95% CI 0.30 to 0.66; 587 participants; 9 trials; low-quality evidence). Intravenous midazolam versus placebo (5 trials; 493 participants)One trial reported that fewer participants who received midazolam were anxious (3/47 versus 15/35; low-quality evidence). There was no difference in discomfort/pain identified in a further trial (3/85 in midazolam group; 4/82 in placebo group; P = 0.876; very low-quality evidence). Oral midazolam versus chloral hydrate (4 trials; 268 participants)Midazolam increased the risk of incomplete procedures (RR 4.01; 95% CI 1.92 to 8.40; moderate-quality evidence). Oral midazolam versus placebo (3 trials; 176 participants)Midazolam reduced pain (midazolam mean 2.56 (standard deviation (SD) 0.49); placebo mean 4.62 (SD 1.49); P < 0.005) and anxiety (midazolam mean 1.52 (SD 0.3); placebo mean 3.97 (SD 0.44); P < 0.0001) in one trial with 99 participants. Two other trials did not find a difference in numerical rating of anxiety (mean 1.7 (SD 2.4) for 20 participants randomized to midazolam; mean 2.6 (SD 2.9) for 22 participants randomized to placebo; P = 0.216; mean Spielberger's Trait Anxiety Inventory score 47.56 (SD 11.68) in the midazolam group; mean 52.78 (SD 9.61) in placebo group; P > 0.05). Intranasal midazolam versus placebo (2 trials; 149 participants)Midazolam induced sedation (midazolam mean 3.15 (SD 0.36); placebo mean 2.56 (SD 0.64); P < 0.001) and reduced the numerical rating of anxiety in one trial with 54 participants (midazolam mean 17.3 (SD 18.58); placebo mean 49.3 (SD 29.46); P < 0.001). There was no difference in meta-analysis of results from both trials for risk of incomplete procedures (RR 0.14, 95% CI 0.02 to 1.12; downgraded to low-quality evidence).
AUTHORS' CONCLUSIONS
We found no high-quality evidence to determine if midazolam, when administered as the sole sedative agent prior to a procedure, produces more or less effective sedation than placebo or other medications. There is low-quality evidence that intravenous midazolam reduced anxiety when compared with placebo. There is inconsistent evidence that oral midazolam decreased anxiety during procedures compared with placebo. Intranasal midazolam did not reduce the risk of incomplete procedures, although anxiolysis and sedation were observed. There is moderate-quality evidence suggesting that oral midazolam produces less effective sedation than chloral hydrate for completion of procedures for children undergoing non-invasive diagnostic procedures.

Journal of Oral Rehabilitation May 2019The purpose of this systematic review was to evaluate the association between sleep bruxism (SB) and anxiety symptoms in adults.
BACKGROUND
The purpose of this systematic review was to evaluate the association between sleep bruxism (SB) and anxiety symptoms in adults.
METHODS
A systematic review was performed and studies assessing SB by means of questionnaires, clinical examination and/or polysomnography (PSG), and validated questionnaires to assess anxiety, were included. Search strategies were developed for seven main electronic databases. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies, and confidence in cumulative evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation criteria.
RESULTS
Eight cross-sectional studies were included, of which five were judged with low and three with moderate risk of bias. No association with SB was observed in three studies that investigated generic levels of anxiety, while other two papers that evaluated generic anxiety levels through the State-Trait Anxiety Inventory (STAI) found a positive association with probable and definite SB in both STAI-1 and STAI-2 subscales. Only one study evaluated dental anxiety in particular and an association with probable SB was observed regarding very anxious or extremely anxious scores. Two studies assessed specific symptoms of anxiety using the panic-agoraphobic spectra evaluation (PAS-SR) questionnaire. Significantly higher PAS-SR total scores were observed in both studies with regard to SB. No study with definitive assessment of SB was identified.
CONCLUSION
Current literature is controversial regarding an association between SB and generic symptoms of anxiety in adults. It seems that some specific symptoms of the anxiety disorders spectrum might be associated with probable SB.

BJPsych Open Jan 2022Recent research has investigated the use of serious games as a form of therapeutic intervention for depression and anxiety in young people. (Review)
Review
BACKGROUND
Recent research has investigated the use of serious games as a form of therapeutic intervention for depression and anxiety in young people.
AIMS
To conduct a systematic review and meta-analysis into the effectiveness of gaming interventions for treating either depression or anxiety in individuals aged 12-25 years.
METHOD
An electronic search was conducted on the 30 March 2020, using PsycINFO, ISI Web of Science Core Collection, Medline and EMBASE databases. Standardised effect sizes (Hedge's g) were calculated for between-participant comparisons between experimental (therapeutic intervention) and control conditions, and within-participant comparisons between pre- and post-intervention time points for repeated measures designs.
RESULTS
Twelve studies (seven randomised controlled trials (RCTs) and five non-randomised studies) were included. For RCTs, there was a statistically significant and robust effect (g = -0.54, 95% CI -1.00 to -0.08) favouring the therapeutic intervention when treating youth depression. For non-RCTs, using a repeated measures design, the overall effect was also strong (g = -0.75, 95% CI -1.64 to 0.14) favouring therapeutic intervention, but this was not statistically significant. Interestingly, we found no statistically significant effect for treating youth anxiety.
CONCLUSIONS
There is preliminary evidence to suggest that gaming interventions are an effective treatment for youth depression, but not anxiety. Further research is warranted to establish the utility, acceptability and effectiveness of gaming interventions in treating mental health problems in young people.
