Use of distraction techniques for the management of anxiety and fear in paediatric dental practice: A systematic review of randomized controlled trials

Procedural sedation and analgesia in pediatric diagnostic and interventional radiology: An expert DELPHI consensus document developed by the ITALIAN scientific society of anesthesia, analgesia, resuscitation and intensive care (SIAARTI)

BACKGROUND

Children undergoing diagnostic and interventional radiology procedures often require sedation to achieve immobility and analgesia if the procedure is painful. In the past decades, leading scientific organizations have developed evidence-based guidelines for procedural sedation and analgesia in children outside of the operating room. Their recommendations are being applied to procedural sedation in radiology. However, some questions remain open regarding specific aspects contextualized to the radiology setting, such as elective prone sedation, the urgency of the procedure, when venous access or airway protection is required, and others.

AIMS

To address the unresolved issues of procedural sedation and analgesia in pediatric diagnostic and interventional radiology.

METHODS

An expert panel of pediatricians, pediatric anesthesiologists, intensivists, and neuroradiologists selected topics representative of current controversies and formulated research questions. Statements were developed by reviewing the literature for new evidence, comparing expertise and experience, and expressing opinions. Panelists' agreement with the statements was collected anonymously using the DELPHI method.

RESULTS

Twelve evidence-based or expert opinion incorporate are presented, considering risks, benefits, and applicability.

CONCLUSIONS

This consensus document, developed by a multidisciplinary panel of experts involved in the field, provides statements to improve the quality of decision-making practice in procedural sedation and analgesia in pediatric radiology.

Effect of audio and virtual reality distraction on the dental anxiety of children with mild intellectual disability

BACKGROUND AND AIM

Intellectual disability, is a neurodevelopmental disorder that typically manifests early in childhood and consists of both intellectual and adaptive functioning deficits in conceptual, social, and practical domains. It can be categorized into mild, moderate, severe, and profound based on its severity. Cognitive impairment may be observed predominantly in children with intellectual disabilities. Marked deficits in areas of learning, planning, communication, social participation, and personal independence in children with mild intellectual disabilities make behavior guidance and communication a challenge during dental treatments. The aim was to evaluate and compare the use of two different distraction tools, audio, and virtual reality (VR) on the dental anxiety of children with mild intellectual disability during dental treatment.

METHODS

Twenty children diagnosed with mild intellectual disability were equally divided into two groups. A cross-over study design consisting of two appointments 1 month apart was employed. In the first appointment, audio and VR distractions were provided to participants in Groups 1 and 2, respectively, and the distraction tools provided to the participants were interchanged in the second appointment. A trained observer recorded physiological parameters (pulse rate and oxygen saturation) and observational parameters (Venham's anxiety rating scale) during both appointments at three-time intervals. Statistical intra-group and inter-group comparison analyses were performed using Friedman's and Mann-Whitney U tests.

RESULTS

A decrease in pulse, increase in oxygen saturation levels, and a decrease in Venham's Anxiety Rating Scores (statistically significant p < .05 / highly significant p < .01) was observed on introducing the distraction techniques in Groups 1 and 2 in both appointments. A statistically non-significant difference (p > .05) in physiological and observational parameters was observed between Groups 1 and 2 in both appointments.

CONCLUSION

Audio and VR distraction techniques can be employed for behavior guidance in children with mild intellectual disability during restorative dental procedures.

The effect of virtual reality glasses on dental anxiety during scaling and root planing in patients with periodontitis: A randomized controlled clinical trial

OBJECTIVES

This study aimed to evaluate the effect of virtual reality distraction (VRD) on dental anxiety during scaling and root planing (SRP) in periodontitis patients.

MATERIALS AND METHODS

This randomized controlled split-mouth study included 60 patients who scored 9 or above on the dental anxiety scale (DAS) and required SRP in at least two quadrants with at least five teeth and two sites with a probing depth of ≥4 mm. Randomly chosen quadrants were treated using virtual reality glasses, and other quadrants were treated without glasses at the same visit. During VRD, a video of nature scenes was projected onto the screen in front of the patient's eyes. DAS and a visual analogue scale about patient feelings were applied at the end of the procedure.

RESULTS

With VRD, the scale value of pain and discomfort level (VASP) was significantly reduced (p = 0.01, d = 0.57). Starting treatment without glasses significantly decreased VASP in both control and test sides (p = 0.00, d = 0.85; p = 0.00, d = 0.80, respectively) and increased the sensation of immersion and realism (p = 0.03, d = 0.45; p = 0.02, d = 0.46, respectively). Intraoperative and postoperative DAS values were significantly lower in patients who started treatment without VRD (p = 0.04, d = 0.34; p = 0.02, d = 0.44, respectively). Of the patients, 63.3% preferred VRD in the subsequent treatment. While patient preference did not correlate with sex, it correlated with age (r = -0.48, p = 0.01).

CONCLUSIONS

The VRD and initiating SRP procedure with VRD affected the pain and discomfort level in anxious periodontitis patients. In addition, the anxiety level was also affected by starting the procedure with glasses.

Efficacy of Virtual Reality Distraction in Reduction of Pain and Anxiety of Pediatric Dental Patients in an Iranian Population: A Split-Mouth Randomized Crossover Clinical Trial

Materials and Methods

This crossover clinical trial was conducted with eligible 6-8-year-old children requiring bilateral mandibular molar pulpotomy. At the first treatment visit, pulpotomy was performed for 15 children using VR glasses distraction while the other 15 children received a pulpotomy without any VR glasses; this trend was reversed at the second session and pulpotomy was performed for the contralateral tooth. Pulse rate (PR) and Modified Child Dental Anxiety Scale (MCDAS) measured the anxiety levels. Wong-Baker Faces Pain Scale (WBFP) assessed the pain perception before and after the intervention. Data were analyzed by Statistical Package for the Social Sciences version 25 using the Mann-Whitney and χ2 tests.

Results

The mean PR was not significantly different between the two groups. However, the test group showed significantly lower scores of MCDAS (P value = 0.02) and WBFP (P value = 0.001) compared with the control group.

Conclusion

The present results suggest that VR headsets can decrease the level of pain and anxiety of patients during primary mandibular pulpotomy. This trial is registered with IRCT20200315046782N1.

Assessment of Medical Clowning in Influencing the Anxiety and Behavior Scores of Children Undergoing Various Dental Treatments and the Stress Levels of the Operator

Aim

To investigate the potential effectiveness of "medical clowns" on preoperative, intraoperative, and postoperative anxiety of children undergoing various dental treatments and also its effect on the operator's stress levels in a dental setup.

Materials and methods

A total of 170 pediatric patients, aged 4-8 years, indicated for preventive therapy, extractions, restorative, and endodontics were included and divided into two groups [group I-audiovisual (A-V) aids; group II-medical clowns], group of 85 patients each after recording Modified yale preoperative scale. Both pre- and postoperatively, Frankl's behavior score was recorded for each patient. During treatment, the face, legs, activity, cry, consolability (FLACC) pain scale, and dental operator's stress level were recorded.

Results

Intervention of medical clowns positively influenced children during dental treatment by increasing their pain threshold. The majority of children showed positive Frankl rating scales after dental treatment. Also, the operator's stress was significantly reduced, which led to enhanced treatment outcomes.

Conclusion

Humor yields the power of healing, distracts pediatric patients, reduces their anxiety, and alleviates their pain, conferring the patients with a sense of laughter, creativity, and care.Therefore, medical clowns in pediatric dentistry can prove to be serviceable and valuable as a nonpharmacological approach to behavior management.

A systematic review and network meta-analysis of virtual reality, audiovisuals and music interventions for reducing dental anxiety related to tooth extraction

BACKGROUND

Tooth extraction is a common procedure performed by oral and maxillofacial surgeons or dentists, often resulting in dental fear and anxiety. The use of relaxing music, audiovisuals, and virtual reality (VR) technologies has been employed to reduce dental anxiety. This network meta-analysis (NMA) aimed to assess the comparative effectiveness of relaxing music, audiovisuals, and VR in reducing dental anxiety associated with tooth extraction.

METHODS

Four electronic databases were searched up to March 8, 2023, to identify randomized controlled trials (RCTs) evaluating different multimedia interventions, including the application of using relaxing music, audiovisuals, and VR technologies for dental anxiety. Studies utilizing various anxiety scales for tooth extraction were considered eligible. The pooled standard mean difference (SMD) and 95% confidence interval (CI) of anxiety scale scores were analyzed using Bayesian NMA.

RESULTS

A total of 11 RCTs were included in this NMA. The Bayesian NMA results demonstrated that relaxing music (SMD = -0.64, 95% CI: -1.04, -0.25) and VR (SMD = -0.54, 95% CI: -1.08, -0.02) were associated with a reduction in dental anxiety, while audiovisuals (SMD = -0.34, 95% CI: -0.97, 0.33) required further consideration. Ranking probabilities indicated that relaxing music might be the most acceptable method for individuals with dental anxiety. The frequentist NMA yielded consistent rankings in a sensitivity analysis.

CONCLUSIONS

Relaxing music shows the greatest potential for reducing dental anxiety related to tooth extraction when compared to other multimedia interventions.

Assessment of Different Distraction Behavioral Methods in Pediatric Dental Clinic: A Systematic Review

Dental anxiety is one of the main problems dentists may face during the treatment of pediatric dental patients; therefore, clinicians tend to perform different behavior management techniques to reduce dental anxiety in children. This review aimed to systematically compare and evaluate the published literature regarding the effects of distraction techniques on anxiety, pain perception, and patient experience during dental practice. A detailed electronic search was conducted on 3 databases including PubMed, Google Scholar, and Cochrane Library. The databases were searched for articles published in the English language between 2015 and 2022. Among 102 studies, 27 studies fulfilled the criteria of eligibility and were included in this study to be analyzed. Numerous approaches have been proposed for the reduction of dental anxiety, out of which the use of audio-visual aids and instruments, active distraction such as tablets, smartphones, and virtual reality glasses showed governance in decreasing the children's anxiety followed by cognitive and behavioral methods.

Effectiveness of Audiovisual Distraction Technique and Filmed Modeling on Anxiety and Fear in Pediatric Dental Patients

Aim

To evaluate the effectiveness of the audiovisual distraction (AVD) technique and filmed modeling (FM) on anxiety and fear in pediatric dental patients.

Materials and methods

This experimental in vivo study was conducted on 80 subjects of age-groups 5-8 years coming to the Department of Pediatric and Preventive Dentistry for their first dental visit. Study subjects were subjected to noninvasive restorative treatment under AVD in group I, FM in group II, and a combination of AVD and FM in groups III and IV (control 0). To assess the level of pre and postoperative anxiety and fear, various biological parameters like pulse rate, oxygen saturation, body temperature, respiratory rate, and salivary cortisol estimation along with facial image scale (FIS), and fear assessment picture scale (FAPS) were used.

Results

Group III (a combination of AVD and FM) came out to be better than other experimental groups and control groups in reducing dental anxiety and fear in pediatric dental patients.

Conclusion

A combination of AVD and FM techniques can be recommended to be used as an effective behavior management technique.

Clinical significance

A child's disruptive behavior due to dental anxiety causes difficulty in delivering effective dental treatment. Thus, a child's behavior management is of paramount importance in the pediatric dental setup. Nonpharmacological behavior management techniques, that is, a combination of AVD and FM techniques can be recommended to be used as an effective behavior management technique to reduce dental anxiety and fear in pediatric dental patients.

Tooth wear prevalence in individuals with Down syndrome: a systematic review

OBJECTIVES

This systematic review investigated the prevalence of tooth wear between patients with and without Down syndrome.

METHODS

Six databases (Embase, LILACS, Livivo, PubMed, Scopus and Web of Science) and grey literature (Google Scholar, OpenGrey and ProQuest) were searched until March 7, 2022. Observational studies were included to assess the differences in tooth wear prevalence and/or severity in Down syndrome and non-syndromic controls. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) recommendations were followed. Three reviewers independently screened studies, extracted data, assessed the methodological quality (Joanna Briggs Institute) and graded the certainty of evidence through the Grading of Recommendations, Assessment, Development, Evaluation (GRADE) approach. Results were summarized through meta-analyses using a random-effects model. The protocol was registered at PROSPERO (CRD42021266997).

RESULTS

Of the 1382 records identified, six cross-sectional studies were included. Individuals with Down syndrome had a higher prevalence and were more likely to have tooth wear than individuals without Down syndrome (44% × 15%; OR = 4.43; 95% CI 3.17-6.18; p < 0.00001; I² = 8%). Also, the severity of tooth wear was higher in the Down syndrome group (n = 275) compared with the controls (n = 294). The certainty of evidence analysis was very low.

CONCLUSIONS

Based on very low certainty of the evidence, patients with Down syndrome had a higher prevalence and likelihood and severity of tooth wear when compared to those without Down syndrome.

CLINICAL RELEVANCE

Screening early tooth wear lesions should be carefully done in the Down syndrome population since its occurrence is remarkable compared to the general population.

Dentophobia and dental treatment: An umbrella review of the published literature

AIMS

Dentophobia is a well-know kind of phobia and psychological problem in dentistry. Although patients might suffer from severe oral pain and have serious health complications, dentophobia is still posing a threat to oral healthcare and remains an unresolved worldwide phenomenon. According to estimates, up to 80% of the general population are affected by this condition. Dentophobia is an unpleasant problem with serious consequences not only for patients but also for dentists and the public health system in general. This umbrella review provides a comprehensive overview of the various aspects of dentophoia as addressed in the published literature, and the current level of knowledge concerning their treatment.

METHODS AND RESULTS

Based on 35 reviews of the published literature, addressing various aspects of dentophobia and published between 2008 and 2021, this umbrella review was written. The search was based on the PubMed and PsycINFO databases. The extraction was structured by open coding and each aspect of the subject analyzed according to Ritchie and Lewis.

CONCLUSION

We conclude that the evidence concerning the efficacy of the various interventions is still rather weak and there is an obvious need for further research, because of the yet and unresolved challenges and the lack of standardised guidelines to deal with patients with dentophobia.

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.

Intraoral clinical examinations of pediatric patients with anticipatory anxiety and situational fear facilitated by therapy dog assistance: A pilot RCT

OBJECTIVE

To evaluate whether the presence of a certified therapy dog specially trained for working in a dental setting may facilitate dental care of anxious pediatric patients.

METHODS

The Norwegian Regional Committee for Medical and Health Research Ethics approved a randomized cross-over trial with a study sample of n = 16 children aged between 6 and 12 years. The trial was registered on clinicaltrials.gov. Pediatric patients referred to specialist care at the Public Dental Service Competence Center of Northern Norway (TkNN) because of anxiety were invited to partake in the trial. Study participants met twice for an intraoral examination by a specialist pediatric dentist. Per random allocation, a therapy dog team was present in the clinic operatory during the clinical examination on the first or the second visit. The primary outcome was the assessment of patient compliance during the intraoral examination (yes/no). Secondary outcomes were measurements of child satisfaction and anxiety using the CFSS-DS scale (Dental subscale of Children's Fear Survey Schedule) completed by a parent/guardian. Supplementary outcomes were salivary cortisol level, heart rate variability, and skin conductance.

RESULTS

Ten boys and six girls (mean age 8.5) were recruited. All completed both clinical visits and demonstrated full compliance while undergoing a dental examination. All study participants and guardians reported great satisfaction. The salivary cortisol level reduction during the clinical examination on the first visit decreased by 30% in the presence of the therapy dog and 20% without, while the decrease during the clinical examination on the second visit was 29% in the presence of the therapy dog and 3% without. Within the limitations of the experimental setup, the electrophysiological measurements were unreliable in the current study population.

CONCLUSION

Dog-assisted therapy in a dental care setting appears to have a positive effect on children with dental anxiety or children that avoid dental care.

Comparative evaluation of the effect of audio and virtual reality distraction on the dental anxiety of healthy and mild intellectually disabled children

Context

Dental environment is one of the most anxiety-provoking stimuli for children, which makes patient management a constant challenge in both typically growing and intellectually disabled children. Distraction is a nonpharmacological technique to manage anxiety in children during dental treatment.

Aim

This study compares the effect of audio and virtual reality (VR) distraction on the dental anxiety of healthy and mild intellectually disabled children.

Methods

Forty children aged 6-14 years were divided into two groups (Group I: children with mild intellectual disability and Group II: healthy children). Groups I and II were further subdivided into two subgroups of 10 children each, based on the distraction technique given to them during the first appointment. After 1 month, we carried out a cross-over of the subgroups. Anxiety levels were measured using physiological and observational parameters at three-time intervals.

Statistical Analysis

Performed using paired t-test for the intergroup comparison and Wilcoxon Signed Rank test for the intra-group comparison.

Results

A decrease in the pulse rate, improvement in oxygen saturation levels, and lower Venham's anxiety rating scores were observed on introducing audio and VR distraction in all the subgroups. The inter-group comparison revealed that audio and VR were more effective in healthy children than children with mild intellectual disabilities.

Conclusions

Audio and VR distraction techniques can be employed successfully to reduce anxiety in children with mild intellectual disability and healthy children undergoing dental restorative treatment.

Assessing an active distracting technique during primary mandibular molar pulpotomy (randomized controlled trial)

OBJECTIVES

This study aims to evaluate the effectiveness of two different distraction techniques (Audio Video Distraction/Video Game Distraction) in the management of anxious pediatric patients during dental treatment.

MATERIALS AND METHODS

One hundred and five children were randomly divided into three groups; Group A: active distraction using video games on a tablet device and wireless joystick (VG). Group B: passive distraction using video on tablet, and wireless headphones (AV). Group C (Control group): basic behavior guidance technique Tell Show Do was used (C). The children were selected from the department of pediatric dentistry at the Faculty of Dentistry, Damascus University, who required pulpotomy in primary mandibular molars. All children were assessed by: Simplified Wong-Baker FACES for pain scale (self-report), and "HOUPT" Behavior Rating Scale for Overall Behavior (non-self-report), at the end of treatment.

RESULTS

One hundred and five children completed the study (57 boys and 48 girls) aged between 6 and 10 years (mean age of 7.4 years). The active distraction (VG) group was superior to the passive distraction (AV) group and the control group (C) on the pain scale with statistically significant differences as appeared in Simplified Wong-Baker Scale (p = .000), The active distraction (VG) group was superior to the control group (C) in overall behavior as appeared in HOUPT scale (p = .041), but it was no statistically significant differences between (VG) group and (AV) group in overall behavior (p = .605). With the use of Bluetooth technology and wireless devices, the workspace was comfortable for the dentist and did not interfere with the movement of his hands.

CONCLUSION

Positive distraction with video games by wireless joystick displayed on the portable tablet on the dental chair was the best technique for reducing dental anxiety and reported pain in school children (6-10 years) and was better than negative distraction by video cartoons on the tablet device.

Basic behavioral management techniques in paediatric dentistry: A systematic review and meta-analysis

OBJECTIVE

To systematically retrieve and assess studies regarding the effectiveness of basic behavioral management techniques (BMTs) in paediatric patients.

DATA SOURCES

Electronic and hand searches were conducted to locate Randomized Controlled Trials (RCTs) reporting on objective and subjective evaluation of anxiety and behavior of children up to 12 years of age. Data extraction and risk of bias evaluation, using the Cochrane risk of bias tool (RoB 2.0 Tool), were performed independently and in duplicate for all included studies. Mean differences and standard deviations were used to summarize the data from each study and meta-analyses were conducted with studies of limited heterogeneity.

STUDY SELECTION

A total of 708 papers were identified and screened, 122 retrieved for full text appraisal and 62 finally included. Results suggested that all basic BMTs have acceptable effectiveness on paediatric patients' anxiety, fear and behavior during dental treatment. Meta-analysis showed a statistically significant difference in favor of distraction for subjective anxiety using facial scale (Mean diff.: 2.78; 95% CI: -3.08, -0.53; p=0.005) and Modified Child Dental Anxiety Scale (Mean diff.: 12.76; 95% CI: -6.09, -4.47; p=0.001) and a non-significant difference for heart rate (Mean diff.: 1.70; 95% CI: -6.54, 0.46; p=0.09). Music significantly reduced heart rate when compared to a control comparator, underlining the superiority of the BMT (Mean diff.: 2.71; 95% CI: -3.70, -0.59; p=0.007).

CONCLUSIONS

Limited evidence about efficacy of one technique over another raises important issues on the topic for future research regarding the management of the child patient in the dental setting of the 21^st century.

CLINICAL SIGNIFICANCE

Behavioral management comprises a challenge for clinicians, who need to be familiar with a range of techniques to meet patients' needs at individual level and be flexible in their implementation. Appropriate technique should incorporate patients' personality and parents' active involvement, within the contents of the changes in modern societies.

Effect of active and passive distraction techniques while administering local anaesthesia on the dental anxiety, behaviour and pain levels of children: a randomised controlled trial

Purpose

The aim of the study was to compare the effect of a stress ball, an active distraction technique with audio-visual eyeglasses, a passive distraction technique during local anaesthesia administration, on dental anxiety (primary outcome), behaviour and pain levels of children (secondary outcomes).

Methods

In this randomised controlled parallel arm trial involving 123 children aged 8–12 years, who required dental treatment under inferior alveolar nerve block, children were randomly allocated into the following three groups: Group 1: Stress ball, Group 2: Audio-visual eyeglasses, Group 3: Control group (basic behaviour guidance without distraction). Dental anxiety was measured using modified child dental anxiety scale and pulse rate, behaviour was rated using Venham’s scale and pain was measured by both self-reporting and observational scales.

Results

No significant difference between the groups was observed for dental anxiety, but a significant decrease was seen in dental anxiety scores within all groups. No significant differences were seen between the groups for behaviour ratings and pain scores.

Conclusion

Use of active stress ball distraction or passive audio-visual eyeglasses during local anaesthesia administration decreased dental anxiety but did not result in a significant improvement in the dental anxiety, behaviour and pain levels when compared to basic behaviour guidance without distraction.

Clinical trial registration

The clinical trial was registered at Clinical Trials Registry–India (CTRI Reg no: CTRI/2019/04/018768, Dated 24 April 2019).

The Relationship between Dental Fear and Anxiety, General Anxiety/Fear, Sensory Over-Responsivity, and Oral Health Behaviors and Outcomes: A Conceptual Model

Dental fear and anxiety (DFA) is common across the lifespan and represents a barrier to proper oral health behaviors and outcomes. The aim of this study is to present a conceptual model of the relationships between DFA, general anxiety/fear, sensory over-responsivity (SOR), and/or oral health behaviors and outcomes. Two rounds of literature searches were performed using the PubMed database. Included articles examined DFA, general anxiety/fear, SOR, catastrophizing, and/or oral health behaviors and outcomes in typically developing populations across the lifespan. The relationships between the constructs were recorded and organized into a conceptual model. A total of 188 articles were included. The results provided supporting evidence for relationships between DFA and all other constructs included in the model (general anxiety/fear, SOR, poor oral health, irregular dental attendance, dental behavior management problems [DBMP], and need for treatment with pharmacological methods). Additionally, SOR was associated with general anxiety/fear and DBMP; general anxiety/fear was linked to poor oral health, irregular attendance, and DBMP. This model provides a comprehensive view of the relationships between person factors (e.g., general anxiety/fear, SOR, and DFA) and oral health behaviors and outcomes. This is valuable in order to highlight connections between constructs that may be targeted in the development of new interventions to improve oral health behaviors and outcomes as well as the experience of DFA.

The Effect of Breathing Exercise Using Bubble Blower on Anxiety and Pain during Inferior Alveolar Nerve Block in Children Aged 7 to 10 Years: A Crossover Randomized Clinical Trial

Introduction. The aim of this study was to evaluate the effect of breathing exercise using bubble blower on anxiety and pain during inferior alveolar nerve block (IANB) in children aged 7 to 10 years. Materials and Methods. In this randomized crossover clinical trial, thirty-five children with moderate to severe anxiety requiring bilateral pulp therapy of mandibular primary molars were enrolled. Based on random lists, 18 children received the BE + IANB and 17 children received a routine IANB at the first session. This trend became reverse at the second visit for each child. Anxiety was measured using Facial Image Scale (FIS), blood pressure, and pulse rate. Face Leg Activity Cry Consolability (FLACC) scale and Wong–Baker Facial Pain Scale (WBFPS) were used for pain measurement. The Paired Samples Test, Wilcoxon Signed Rank Test, and Interclass Correlation Coefficient were used for data analysis. Results. The means of FLACC, WBFPS, FIS, blood pressure, and pulse rate were higher at the control visit. However, these differences were statistically significant only for FLACC scale and WBFPS ( $P$ value <0.05). In subgroup analysis, only girls and children without any previous dental treatment showed significant differences in FLACC scale and WBFPS between the control and bubble blower side ( $P$ value <0.05). Conclusion. Breathing exercise using a bubble blower may be an efficient distraction and relaxation method to decrease pain of 7- to 10-year-old children with moderate to severe anxiety during inferior alveolar nerve block. However, anxiety levels were lower when applying BE, and the differences were not statistically significant.

Adolescent Dental Fear and Anxiety: Background, Assessment, and Nonpharmacologic Behavior Guidance

Adolescence, the period from 11 to 21 years of age, bridges the chasm between childhood and adulthood. Adolescence can be challenging as bodies, cognition, and personality go through major transformations, but it is also a time of great joy as confident adults with a clear identity develop. Dentists need to be knowledgeable about the developmental characteristics of this group because some of the cognitive and emotional changes make adolescents vulnerable to new fears. Dentists must tailor behavior guidance to this developing psyche in a way that respects independence and promotes confidence to foster lifelong positive views of dentistry.

Efficacy of audiovisual distraction using eyeglasses during dental care: a randomized clinical trial

This randomized parallel-group control trial tested the efficacy of distraction using audiovisual eyeglasses (AVE) during dental procedures [NCT03902158]. Forty-four 6-9 year-old children with low/moderate anxiety and who needed restorative treatment or exodontia of the primary molars were randomly allocated into two groups: the AVE (experimental) and the conventional behavior management techniques (control) groups. Motion sensors were used to measure the participants' body movements. Dental visits were video recorded, and their pain levels and behavior were assessed using the Faces, Legs, Activity, Cry, and Consolability Behavioral Pain Assessment Scale and the Venham Behavioral Scale, respectively. Anxiety was assessed via heart rate measurements. After treatment, the children scored their pain using the Faces Pain Scale. Mann-Whitney U and chi-square tests were used to compare the groups. The mean score on the behavioral scale was 0.59 in the experimental group and 0.72 in the control group under local anesthesia (p = 0.73). During the procedure, the mean score was 0.41 in the experimental group and 1.32 in the control group (p = 0.07). The mean heart rate was similar in both groups (p = 0.47), but a significant increase during treatment was observed in the control group. There was no difference between the groups in terms of pain, behavior, and self-reported pain scores (p = 0.08). Children aged 6-7 who used the AVE had fewer wrist movements (435.6) than that of children in the control group (1170.4) (p = 0.04). The AVE achieved similar results to the basic behavior management techniques, with good acceptance by the children.

The Effect of Transcutaneous Electric Nerve Stimulation (TENS) on Anxiety and Fear in Children Aged 9-14 Years

Introduction

Dental fear or dental phobia is caused by previous unpleasant dental experiences and pain. It can result in delaying or avoiding dental visits. Most often it leads to individuals avoiding visiting the dentist until physical pain completely impairs the quality of life.

Objectives

Transcutaneous electrical nerve stimulation (TENS) is a method of pain relief involving the use of a mild electrical current. The main aim of this study was to examine whether the TENS device affects the reduction of anxiety and fear during dental procedures.

Material and Methods

The study was conducted on a sample of 125 respondents, aged 9-14 years. Statistical significance of differences between pre- and post-treatment results on all applied measuring instruments was verified by the t-test for dependent samples. The calculation was performed for all respondents and individually for the three observed groups. The Children`s Fear Survey Schedule – Dental Subscale test was used to assess anxiety and fear.

Results

The results on the CFSS-DS scale in all subjects did not differ statistically significantly before and after treatment (p > 0.05). The results on the CFSS-DS scale in subjects who received TENS were statistically significantly different before and after treatment (p < 0.01). The results on the CFSS-DS scale in subjects who received local anesthesia were statistically significantly different before and after treatment (p < 0.05).

Conclusion

The TENS device had an anxiolytic effect after the first visit.

Effects of music listening to reduce preprocedural dental anxiety in special needs patients

BACKGROUND AND PURPOSE

Dental anxiety is particularly problematic for individuals with Intellectual and Developmental Disabilities (IDD), resulting in a greater reluctance to undergo dental procedures and exacerbating poor oral health. Drugs commonly used for dental anxiety have undesirable side effects and may not be preferred by patients and guardians. Alternative methods for managing dental anxiety are needed. The purpose of this study was to evaluate the effects of music listening on anxiety levels of patients with IDD awaiting dental procedures.

MATERIALS AND METHODS

A convenience sample of 15 patients with IDD listened to piano music for 10 min before scheduled outpatient dental procedures. Preprocedural dental anxiety levels as measured by Revised ADAMS scores, pulse rates, and blood pressures were compared pre and post music listening. Participants' premedication requirements for the procedure with music listening was compared to their respective previously scheduled procedure with no music listening.

RESULTS

Post music listening, patients demonstrated reduced anxiety levels as evidenced by lower Revised ADAMS scores (p = 0.001), mean arterial pressures (p = 0.09), pulse rates (p = 0.02), and reduced premedication requirements.

CONCLUSION

Study results suggest that music listening offers an effective, nonpharmacologic alternative to reducing preprocedural dental anxiety in patients with IDD.

"Mom Let's Go to the Dentist!" Preliminary Feasibility of a Tailored Dental Intervention for Children with Autism Spectrum Disorder in the Italian Public Health Service

Children with autism spectrum disorder (ASD) show worse oral health than their peers. Their access to health services is, at present, inadequate: few high-quality interventions have been designed and implemented to improve their care procedures so far. The purpose of this study is to describe an experience of dental care supported by Information and Communication Technologies (ICT), for children with ASD in a public health service. In our study, 59 children (mean age 9.9 years; SD = 5.43) participated in the MyDentist project. It integrates classic dental care techniques with new practices for desensitization and fear control, delivered through an enhanced customized ICT-based intervention aiming at familiarizing the child with ASD with the medical setting and procedures. Two questionnaires were filled out by parents to describe the acceptability of the MyDentist experience for their children. Significant results were shown from T0 (before initiating MyDentist) to T1 (after 6 months of the MyDentist experience) regarding improved oral hygiene and cooperation during dental treatments. Families positively assessed the use of ICT support. In conclusion, the project demonstrated acceptability by parents, suggesting that public health dental care and prevention can be successfully implemented without resorting to costly pharmacological interventions (with potential side effects), taking better care of children's health.

Dog-assisted therapy in the dental clinic. Part B. Hazards and assessment of potential risks to the health and safety of the dental therapy dog

Background

A dental therapy dog may help anxious patients in the dental clinic overcome their fear and facilitate the completion of necessary dental care. Dental clinic activities are associated with hazards that may pose potential risks to the health and safety of the dental therapy dog.

Objectives

To describe potential hazards associated with risks to health and safety to therapy dogs in dental clinics and to present suggestions for risk minimisation by adopting best practices in dental clinic settings.

Materials and method

Literature searches in Medline, http://Clinicaltrials.gov, and Google Scholar for qualitative and quantitative assessments of occupational hazards and risks in dental clinics, in combination with a review of the reference list of the included studies. Identified hazards and risks were analysed relative to their relevance for the health and welfare of a therapy dog present in a dental clinic setting.

Results

Workplace hazards in the dental clinic that apply to both humans and therapy dogs are allergies, sharps injury, eye injury, stress, rhinitis, hearing impairment, and other hazards. Additional concerns associated with risks for the dental therapy dog are situations involving erratic patient behaviour and threats if the patient is an undisclosed disease carrier. Risks to the health and safety of the dental therapy dog in the clinics are present but are low if the dental clinical staff and dog handlers comply with best practices.

Conclusions

Best practice includes awareness amongst the clinic staff and the dog handler of all potential hazards in the dental clinic and on how to reduce these hazards as well as adverse events that may scare the dental therapy dog. The dental therapy dog team must be specially trained to work in a dental clinic. Each treatment session has to be exclusively tailored to that specific appointment and the individual patient.

'Message to Dentist': Facilitating Communication with Dentally Anxious Children

Dental anxiety affects children worldwide and can have negative consequences on oral health. This study aimed to evaluate a novel communication aid ‘message to dentist’ (MTD), as part of a wider cognitive behavioural therapy approach to reduce dental anxiety in young patients. Dentally anxious children, aged 9–16 years, were invited to complete the MTD proforma, before and following their course of treatment. They scored how worried they were and their anticipated pain levels on a scale of 1–10 (10 being the worst outcome). They also wrote down their coping plans and post-treatment reflections. One hundred and five children, from a UK general dental practice and a hospital clinic, were included. They had a mean age of 11.6 years, and 65% were female. There was a significant reduction in self-report worry (from 4.9 to 2.1) and anticipated pain (from 5.1 to 2.0) scores (p < 0.05, paired t-test). Many children (30%) used listening to music/audiobook as a coping strategy. Thematic analysis revealed concerns around pain, uncertainty, errors and specific procedures. The MTD proforma proved an effective means of facilitating communication between anxious children and the dental team, allowing them to identify their worries and make personalised coping plans.
