The use of dental anxiety management techniques during one-session treatment: a study on five video-recorded patient cases.

OBJECTIVE: The aim was to examine what kinds of dental anxiety management techniques dentists use in the context of one-session treatment. MATERIAL AND METHODS: The data consisted of videotaped treatment sessions for five dentally anxious adults. The treatment was conducted by two experienced dentists without formal training in the treatment of dentally anxious patients or behavioral management techniques. Theory-driven qualitative content analysis, based on the anxiety management classification of Milgrom et al. was used to identify and classify the techniques used during the treatments. RESULTS: Altogether, diverse categories of dental anxiety management techniques were identified under the main themes of enhancing trust and control and psychological management. Techniques that fell into enhancing trust and control included the categories of 'building a trustful relationship', 'informational control', and 'behavioral control'. These techniques were used consistently throughout the sessions. Additionally, psychological management techniques were identified and classified as 'behavioral strategies: relaxing the body' and 'cognitive strategies: relaxing the mind', which were regularly used in specific situations. CONCLUSION: The results indicate that a variety of dental anxiety management techniques were used during one-session treatments. The findings provide valuable insights for dentists in managing their patients with dental anxiety and improving their overall treatment experience.

Leveraging technology to increase the disseminability of evidence-based treatment of dental fear: An uncontrolled pilot study.

OBJECTIVES: U.S. and global estimates indicate that over 30% of adults fear receiving dental care, including over 20% who have visited a dentist in the last year, leading to avoidance and degraded oral and systemic health. Although evidence-based cognitive-behavioral treatments for dental fear (CBT-DF) exist, they have little impact on the millions who seek dental care annually because they are not disseminable (6 h of in-chair time, delivered only in person at a few sites). We developed a disseminable CBT-DF stepped-care treatment comprising (Step 1) a mobile-health application and, for those who remain fearful, (Step 2) a 1-h, one-on-one psychological treatment session that allows practice during exposure to the patient's most-feared stimuli. We hypothesized that the treatment would (a) be rated highly on usability and credibility and (b) result in clinically consequential (i.e., lowering fear into the 0-3 "no/low fear" zone) and statistically significant changes in global dental fear. METHOD: Racially/ethnically diverse patients (N = 48) with moderate to severe dental fear were recruited; all completed Step 1, and n = 16 completed Step 2. RESULTS: As hypothesized, users found the stepped-care treatment highly usable, credible, and helpful. Critically, this stepped-care approach produced reductions in patients' dental fear that were both clinically consequential (with half no longer fearful) and statistically significant (d = 1.11). CONCLUSIONS: This usable, credible, stepped-care approach to dental fear treatment holds promise for liberating evidence-based CBT-DF from specialty clinics, allowing broad dissemination.

Changes in symptoms of anxiety, depression, and PTSD in an RCT-study of dentist-administered treatment of dental anxiety.

BACKGROUND: Educating dentists in treatment methods for dental anxiety would increase the patients' access to treatments that are important to their oral health. However, to avoid adverse effects on comorbid symptoms, involvement by a psychologist has been considered necessary. The objective of the present paper was to evaluate whether a dentist could implement systematized treatments for dental anxiety without an increase in comorbid symptoms of anxiety, depression or PTSD. METHODS: A two-arm parallel randomised controlled trial was set in a general dental practice. Eighty-two patients with self-reported dental anxiety either completed treatment with dentist-administered cognitive behavioural therapy (D-CBT, n = 36), or received dental treatment while sedated with midazolam combined with the systemized communication technique "The Four Habits Model" (Four Habits/midazolam, n = 41). Dental anxiety and comorbid symptoms were measured pre-treatment (n = 96), post-treatment (n = 77) and one-year after treatment (n = 52). RESULTS: An Intention-To-Treat analysis indicated reduced dental anxiety scores by the Modified Dental Anxiety Scale (median MDAS: 5.0 (-1,16)). The median scores on the Hospital Index of Anxiety and Depression (HADS-A/D) and the PTSD checklist for DSM-IV (PCL) were reduced as follows: HADS-A: 1 (-11, 11)/HADS-D: 0 (-7, 10)/PCL: 1 (-17,37). No between-group differences were found. CONCLUSIONS: The study findings support that a general dental practitioner may treat dental anxiety with Four Habits/Midazolam or D-CBT without causing adverse effects on symptoms of anxiety, depression or PTSD. Establishing a best practice for treatment of patients with dental anxiety in general dental practice should be a shared ambition for clinicians, researchers, and educators. TRIAL REGISTRATION: The trial was approved by REC (Norwegian regional committee for medical and health research ethics) with ID number 2017/97 in March 2017, and it is registered in clinicaltrials.gov 26/09/2017 with identifier: NCT03293342.

Investigation of the effect of music listened to by patients with moderate dental anxiety during restoration of posterior occlusal dental caries.

OBJECTIVE: The aim of this randomized controlled study was to investigate the effect of music therapy during restorative dental treatments on patients with moderate dental anxiety. MATERIALS AND METHODS: Seventy patients were determined to have moderate dental anxiety by the Modified Dental Anxiety Scale (MDAS) and were divided randomly into two groups (n = 35). The first group did not listen to music during their restorative treatment (control group), and the second group listened to music of their choice (experimental group). Systolic blood pressure, diastolic blood pressure, heart rate, oxygen saturation, and body temperature were measured three times for each patient: once before the treatment, once after their dental caries were removed, and once at the end of the treatment. Salivary cortisol samples were taken from each patient before and after the treatment. The MDAS was re-administered to the patients at the end of the treatment, and the data were analyzed statistically. RESULTS: Only the diastolic blood pressure (P = 0.042) and the MDAS scores of the experimental group (P = 0.001) were significantly lower than the control group at the end of the treatment. CONCLUSION: While music listening did not have an effect on the physiologic parameters of the patients during restorative treatment, it decreased the MDAS scores of the patients. CLINICAL RELEVANCE: Although music therapy did not affect the physiological parameters during the restorative dental treatment, it may help to reduce patients' self reported anxiety level.

Effect of Acupressure on Dental Anxiety in Children: a Pilot Study for a Randomized Clinical Trial.

Background: Anxiety is an important problem in children in dental clinics. Acupressure may be a useful tool to assist in dental procedures in anxious children. Objectives: This pilot study was performed to examine the effects of acupressure on dental anxiety in children undergoing restorative procedures. Methods: Fourteen children aged 7-10 years and with at least one primary molar with caries on the dentine were included in the study. The participants also needed to score at least one point on the modified Venham Picture Test (VPTm) for the determination of anxiety. The children were randomly allocated to two groups: group A - non-documented points for the reduction of anxiety and induction of relaxation; group B - documented points (EX-HN3, Shen Men of auricular acupuncture). The anxiety scale was administered on three occasions: prior to the application of acupressure; immediately after sitting in the dental chair to undergo restorative treatment; and after removal of acupressure at the end of the restorative procedure. Heart rate (HR) was measured when each child sat in the dental chair, after the removal of carious tissue, and after the removal of acupressure. Results: After the procedure, HR (as an indicator of anxiety) was statistically significantly lower in group B than group A (p = 0.02). However, there was no significant difference between the groups regarding anxiety before and during the restorative procedure (VPTm and HR: p > 0.05). Conclusion: The children who received acupressure on documented points for the reduction of anxiety had a significantly lower HR after the restorative procedure. No significant between-group difference was found regarding anxiety measured using a psychometric evaluation (VPTm).

Management strategies for adult patients with dental anxiety in the dental clinic: a systematic review.

Anxiety is an adaptive emotional response to potentially threatening or dangerous situations; moderated by the sympathetic nervous system. Dental anxiety is common and presents before, during or after dental treatment. The physiological response includes an increase in heart rate, blood pressure, respiratory rate, and cardiac output. Consequently, extensive distress leads to avoidance of dental treatment and multiple failed appointments, impacting both oral and general health. Dental anxiety can generate a variety of negative consequences for both the dentist and the patient. Evidence-based strategies are essential for mitigating and relieving anxiety in the dental clinic. Psychotherapeutic behavioural strategies can modify the patient's experience through a minimally invasive approach with nil or negligible side effects, depending on patient characteristics, anxiety level and clinical situations. These therapies involve muscle relaxation, guided imagery, physiological monitoring, utilizing biofeedback, hypnosis, acupuncture, distraction and desensitization. Pharmacological intervention utilizes either relative analgesia (nitrous oxide), conscious intravenous sedation or oral sedation, which can have undesirable side effects, risks and contraindications. These modalities increase the cost and availability of dental treatment.

Dental anxiety treatment by a dentist in primary care: A 1-year follow-up study.

In an earlier randomized controlled trial of dental anxiety treatments (n = 96) we compared the effects of dentist-administered cognitive behavioural therapy (D-CBT) and dental treatment supplemented with the Four Habits communication model plus midazolam sedation. Both treatments, applied in a general dental practice, were associated with a clinically relevant decrease in dental anxiety. In this follow-up study, 52 of the 82 treatment completers responded to an online questionnaire 1 year post-treatment. Reduction in dental anxiety persisted for both treatment groups. From baseline to 1 year post-treatment the Modified Dental Anxiety Scale was reduced by 7.8 [SD: 4.4; Cohen's d effect size: 1.2 (CI: 0.8-1.7)] and 7.8 [SD: 4.2; Cohen's d: 1.4 (0.9-1.8)] in the D-CBT and Four Habits/midazolam groups, respectively. Most patients (74% for D-CBT, 80% for Four Habits/midazolam) continued with dental treatment. Nine patients in the D-CBT and seven in the Four Habits/midazolam groups received additional CBT treatment from a psychologist/dentist team. Both methods tested should be accessible to interested dentists who receive adequate training. Effective first-line treatments for dental anxiety in general dental practice can generate more accessible care pathways for patients with dental anxiety. Evidence-based dental anxiety treatment programmes should be included in the dental curriculum and established as best practice for dentists.

The variables associated with dental anxiety and their management in primary care dental clinics in Bahrain: a cross-sectional study.

BACKGROUND: 20-80% of adults presenting to a dental clinic experience anxiety. Negative past dental experiences and environmental factors such as the waiting area of a dental clinic or sound of a drill are commonly considered triggering factors for anxiety. Anxiety management strategies are considered a part of routine dental procedure, due to increased prevalence and compromised patient care. Hence the aim of the present study is to identify the prevalence and variables associated with dental anxiety and their management in patients visiting the primary care dental clinics in Bahrain. METHOD: Four hundred and eighty participants were included. A 3-part questionnaire deciphered the demographic characteristics of the participants, the dental procedure undertaken, the level of anxiety, and the management strategy used by the dentist. The pre and post-treatment MDAS scores were recorded. Paired t test, ANOVA and Wilcoxon signed rank test was used to test the level of significance between the variables and the mean MDAS scores. The p ≤ 0.05 was considered statistically significant. RESULTS: The prevalence of dental anxiety was 23.7% with moderate anxiety, and 11.4% with high anxiety. Females presented with a higher mean MDAS both pre and post-treatment compared with males. A statistically significant difference between the pre and post-treatment MDAS scores were observed in educated patients less than 50 years of age. Those with unpleasant previous dental experience showed statistically significant difference. Analyses of anxiety management techniques showed that single techniques worked better than combination techniques. Rest and breaks combined with any other technique of choice showed significant reduction in the MDAS scores post treatment. CONCLUSION: To conclude, all patients attending the dental clinic present with some level of anxiety that necessitates the dentist to use anxiety management strategies. Non-pharmacological methods that are non-invasive must be the first choice. Rests and breaks, with any technique of choice provides the best possible anxiety management. It is possible to achieve the desired anxiety reduction in single visit to complete the planned dental intervention, other than in patients who are dental phobic.

The methods and use of questionnaires for the diagnosis of dental phobia by Japanese dental practitioners specializing in special needs dentistry and dental anesthesiology: a cross-sectional study.

BACKGROUND: Dental phobia is covered by medical insurance; however, the diagnostic methods are not standardized in Japan. Therefore, the aim of this study was to investigate the methods and use of questionnaires for the diagnosis of dental phobia by Japanese dental practitioners specializing in special needs dentistry and dental anesthesiology. METHODS: We conducted an online survey to obtain information from the members of the Japanese Society for Disability and Oral Health (JSDH, n = 5134) and the Japanese Dental Society of Anesthesiology (JDSA, n = 2759). Response items included gender, qualification, affiliation type, methods of diagnosis and management of dental phobia, use of questionnaire, need to establish standardized diagnostic method for dental phobia, and others. The chi-squared test was used to compare answers between the three groups: JSDH only, JDSA only, and both JSDH and JDSA. Multiple logistic regression analysis was conducted to identify factors associated with the use of an assessment questionnaire. RESULTS: Data were obtained from 614 practitioners (JSDH only, n = 329; JDSA only, n = 195; both JSDH and JDSA: n = 90, response rate: 7.8% [614/7,893], men: n = 364 [58.5%]). Only 9.7% of practitioners used questionnaires to quantify the level of dental anxiety. The members of both JSDH and JDSA group used questionnaires more frequently than members of the JSDH only (19% and 7.1%, respectively; Bonferroni corrected p < 0.01). Most practitioners (89.1%) diagnosed dental phobia based on patient complaints of fear of treatment. Furthermore, majority of the participants (73.3%) felt the need to establish standardized diagnostic method for "dental phobia." Multiple logistic regression analysis showed that membership of the JSDH only was negatively related (odds ratio [OR] 0.28, 95% confidence interval [CI] 0.13-0.60), and use of behavioral therapy was positively related (OR 2.34, 95% CI 1.18-4.84) to the use of a questionnaire. CONCLUSIONS: The results of this study showed that the use of questionnaires was very low, patients' subjective opinions were commonly used to diagnose dental phobia, and a standardized diagnostic criterion was thus needed among practitioners. Therefore, it is necessary to establish diagnostic criteria for dental phobia in line with the Japanese clinical system and to educate dentists about them.

Seeing the person before the teeth: A realist evaluation of a dental anxiety service in Norway.

Patients with a trauma history, whether sexual abuse or torture, or dental phobia, tend to avoid dental services due to severe dental anxiety. Subsequently, they experience poor oral health, lower quality of life, and poorer general health. In Norway, a specific service (torture, abuse, and dental anxiety [TADA]) targets these patients' dental anxiety through cognitive behavioural therapy (CBT) prior to dental restoration. By exploring patients' experiences with TADA services using a realist evaluation approach, this paper aims to increase our understanding of how this type of service addresses patients' dental anxiety in terms of its mechanisms and contextual factors. Interviews with TADA patients (n = 15) were analysed through a template analysis driven by context-mechanism-outcome heuristics. The analysis revealed that patients value a dental practitioner who provides a calm and holistic approach, positive judgements and predictability elements that lean towards a person-centred care approach. Provided this, patients felt understood and cared for, their shame was reduced, self-esteem emerged, and control was gained, which led to alleviation of dental anxiety. Therefore, our findings suggest that combining CBT with a person-centred care approach helps alleviate patients' dental anxiety. This provides insights into how dental services could be executed for these patients.

Atraumatic restorative treatments and oral health-related quality of life and dental anxiety in Australian Aboriginal children: A cluster-randomized trial.

OBJECTIVES: The management of early childhood caries is challenging and the impacts of its treatment on child oral health-related quality of life (COHRQoL) and dental anxiety among Australian Aboriginal children is relatively unknown. The aim of the study was to compare the impact on COHRQoL and dental anxiety after approximately 12 months among Aboriginal children treated for early childhood caries (ECC) using the Atraumatic Restorative Treatment and the Hall Technique (ART/HT: test) or standard care (control). METHODS: Consenting Aboriginal communities in the North-West of Western Australia were randomized into early (test) or delayed (control) intervention for the management of ECC. Children and parents/carers completed a questionnaire at baseline and at follow-up. The questionnaire sought information on COHRQoL using the proxy-reported Early Childhood Oral Health Impact Scale (ECOHIS) and the self-reported Caries Impacts and Experiences Questionnaire for Children (CARIES-QC). The test group was provided with the ART/HT care at baseline while the control group was advised to seek care through the usual care options available within the community. At follow-up, both groups were offered care using the ART/HT approach. Changes in the mean scores from baseline to follow-up within groups were evaluated using appropriate paired (t-test, Wilcoxon paired test), and between groups with unpaired tests (t-test). Multivariate regression analysis after multiple imputations of missing data used generalized estimating equation (GEE) controlling for clustering within communities. RESULTS: Twenty-five communities and 338 children (mean age = 3.6 years, sd 1.7) participated in the study (test = 177). One child was excluded from the analysis because of a missing questionnaire and clinical data at baseline and follow-up. At baseline, test group children were older (test = 3.8 years, 95% CI 3.6-4.1;control = 3.3 years, 95% CI 3.1-3.6) and had higher caries experience (test dmft = 4.4, 95% CI 3.8-5.0;control dmft = 3.1, 95% CI 2.5-3.7), but there was no significant difference in COHRQoL or anxiety levels between the groups. At follow-up, parents in the delayed intervention reported worsening of COHRQoL (70% worsening of the family impact section of the ECOHIS and 37% worsening of the total ECOHIS scale), and there was an 8% reduction in child dental anxiety among the early treatment group. CONCLUSIONS: The application of the ART/HT approaches was feasible, effective, and impacted positively on child oral health-related quality of life and child dental anxiety among Aboriginal children in remote communities. The model of care as tested in this study should be further developed for inclusion in main-stream service delivery programmes.

Laser acupuncture and intravascular laser irradiation of blood for management of pediatric dental anxiety.

The aim of this study was to assess the effectiveness of laser acupuncture and intravascular laser irradiation of blood (ILIB) for managing anxiety in pediatric dentistry. Eighty-four children recruited at a university dental clinic were randomly assigned to three groups: the Sham group (n = 27) underwent sham laser irradiation of three acupuncture points, the ILIB group (n = 25) underwent 10 min of ILIB, and the laser acupuncture group (LAC, n = 32) underwent 40 s of laser acupuncture over points VG20 (Baihui), PC6 (Neiguan), and the Oppression Point. The results suggest that ILIB and laser acupuncture are feasible alternatives for managing dental anxiety in children.

Dentist-administered cognitive behavioural therapy versus four habits/midazolam: An RCT study of dental anxiety treatment in primary dental care.

The study aimed to test the effectiveness of cognitive behavioural therapy (CBT) administered by a general dental practitioner (GDP) in a general dental practice. In a two-arm parallel randomised controlled trial, the experimental group received a short dentist-administered CBT-intervention (D-CBT). A best-practice control group (FHM) received dental treatment during sedation with midazolam combined with an evidence-based communication model (The Four Habits Model). Ninety-six patients with self-reported dental anxiety were allocated to the treatment arms at a 1:1 ratio. Modified Dental Anxiety Scale (MDAS) scores spanned from 12 to 25, and 82 patients (85%) had a score of 19 or more, indicating severe dental anxiety. In both treatment arms, scores on MDAS and Index of Dental Anxiety and Fear (IDAF-4C) decreased significantly, but no differences were found between treatment arms. Mean reductions were: MDAS scores: -6.6 (SD = 0.5); IDAF-4C scores: -1.0 (SD = 1.1). In conclusion, local GDPs in general dental practices with proper competence have the ability for early detection of dental anxiety and, with the use of a manual-based D-CBT or FHM treatment, GDPs could offer efficient first-line treatment suitable for dental anxiety of varying severities.

Genes in treatment: Polygenic risk scores for different psychopathologies, neuroticism, educational attainment and IQ and the outcome of two different exposure-based fear treatments.

OBJECTIVES: Evidence for a genetic influence on psychological treatment outcome so far has been inconsistent, likely due to the focus on candidate genes and the heterogeneity of the disorders treated. Using polygenic risk scores (PRS) in homogenous patient samples may increase the chance of detecting genetic influences. METHODS: A sample of 342 phobic patients treated either for clinically relevant dental fear (n = 189) or other (mixed) phobic fears (n = 153) underwent highly standardised exposure-based CBT. A brief five-session format was used to treat dental fear, whereas longer multi-session treatments were used with the mixed-fear cohort. PRS were calculated based on large genetic studies of Neuroticism, Educational Attainment (EA), Intelligence, and four psychopathology domains. We compared PRS of post-treatment and follow-up remitters and non-remitters and regressed PRS on fear reduction percentages. RESULTS: In the dental fear cohort, EA PRS were associated with treatment outcomes, i.e. drop-out, short- and long-term remission state, fear reduction, and attendance of subsequent dental appointments. In the mixed fear treatment cohort, no gene effects were observable. CONCLUSIONS: Results indicate the importance of EA-related traits for outcomes following brief, but not long, standardised exposure-based CBT. Such use of PRS may help inform selection and tailoring of treatments.

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.

Binaural beats or 432 Hz music? which method is more effective for reducing preoperative dental anxiety?

BACKGROUND: The aim of this prospective clinical study was to investigate the effectiveness of binaural beats and music at a frequency of 432 Hz and compare which method is more effective for reducing preoperative dental anxiety in impacted third molar surgery. MATERIAL AND METHODS: Ninety patients were randomly selected to the binaural beats group, music group and control group. Visual analog scale used to evaluate dental anxiety before the local anesthesia in the first measurement. Local anesthesia was applied to the all patients. Patients in the music group listened to 432 Hz tuned music using earphones for 10 minutes. Patients in the binaural beats group listened to binaural beats using earphones (for the right ear, 220 Hz and for the left ear 210 Hz) for 10 minutes. No special treatment was applied to the patients in control group. In the second measurement, dental anxiety was measured again in all three groups. For analysis of differences between three groups was used One way Anova and Kruskal Wallis test. RESULTS: Twenty seven male and 53 female patients included the study. In the first measurement, the same level of anxiety was recorded in all three groups. (p = 0.811) There was a significant decrease in anxiety in both the binaural beats and music group in the second measurement. (p < 0.001). CONCLUSIONS: Binaural beats and 432 Hz tuned music are a valid non pharmacological adjuvant to reduce dental anxiety in impacted third molar surgery. They have a positive effect to reduce the dental anxiety

Hipnose no controle do medo e da ansiedade em odontopediatria: revisão integrativa da literatura / Hypnosis in the control of pain and anxiety in pediatric dentistry: an integrative literature review

Objetivo: Analisar a literatura científica acerca da eficácia da hipnose como técnica de gestão comportamental para reduzir a dor e/ou a ansiedade no tratamento odontopediátrico. Metodologia: A partir da pergunta norteadora "Qual é a efetividade da hipnose no manejo comportamental de crianças durante o tratamento odontológico?", foi realizada uma busca nas bases de dados BVS, Cochrane Library, Google Acadêmico e PubMed, seguindo uma estratégia de combinação das palavras-chave "Odontopediatria" (Pediatric Dentistry), "Hipnose em Odontologia" (Hypnosis, Dental) e "Ansiedade ao tratamento odontológico" (Dental Anxiety). Não houve restrição com relação ao ano de publicação, idioma ou local em que o estudo foi realizado. A seleção dos estudos foi realizada em três etapas: por meio do processo de leitura dos títulos e resumos, exclusão de artigos duplicados e obtenção e leitura dos artigos completos selecionados. Resultados: De um total de 40 artigos encontrados, quatro foram selecionados, sendo incluídos manualmente mais dois numa busca manual nas referências dos artigos identificados e optou-se por acrescentar duas pesquisas. Desta forma, as referências dos artigos selecionados tornaram-se fontes de identificação de novos artigos, após conferência da lista de referências dos artigos incluídos, totalizando seis artigos analisados. Essas pesquisas foram conduzidas em diversos países como México, Índia, França, Turquia e Estados Unidos. Trezentas e quarenta e uma crianças foram analisadas, com idade variando de quatro a 16 anos. A hipnose, na maioria das pesquisas, foi avaliada antes e durante o procedimento odontológico anestésico local. A frequência cardíaca e a saturação de oxigênio foram medidas utilizadas para avaliar a ansiedade dos pacientes e a resistência física, entre outras ferramentas, foi utilizada para avaliar a dor em três pesquisas. Conclusão: A hipnose diminuiu significativamente a frequência cardíaca, a resistência física (principalmente o choro), a ansiedade e a dor em procedimentos de injeção anestésica local, e aumentou significativamente a cooperação dos pacientes Odontopediátricos, no entanto são necessários mais estudos randomizados sobre esse tema, com padronização metodológica, considerando o alto risco de viés encontrado nas pesquisas.

Aim: To analyze the scientific literature about the effectiveness of hypnosis as a behavior-al management technique used to reduce pain and/or anxiety in the pediatric treatment. Methods: Based on the guiding question "What is the effectiveness of hypnosis in the man-agement of children's behavior during dental treatment?", a bibliographic search was car-ried out on the BVS, Cochrane Library, Google Scholar, and PubMed databases by com-bining the keywords "Pediatric Dentistry", "Hypnosis, Dental", and "Dental Anxiety". There was no restriction concerning year of publication, language, or place. The selection of studies was carried out in three stages: through the process of reading the titles and ab-stracts, by excluding duplicate articles, and obtaining and reading the selected full articles. Results: Out of 40 articles found, we selected four. Two articles were then included manu-ally, totaling six articles.The surveys were conducted in several countries, such as Mexico, India, France, Turkey, and the United States. Three hundred and forty-one children, aged from four to 16 years old, were analyzed. Hypnosis, in most studies, was assessed before and during the local anesthetic dental procedure. Heart rate and oxygen saturation were used to assess patients' anxiety, and physical resistance, among other tools, was used to as-sess pain in three studies. Conclusion: Hypnosis significantly reduced heart rate, physical resistance (mainly crying), anxiety, and pain in local anesthetic injection procedures. Also, it significantly increased the cooperation of pediatric patients; however, more randomized studies on this topic, with methodological standardization, are necessary considering the high risk of bias found in the studies.

The effects of lavender aromatherapy on stress and pain perception in children during dental treatment: A randomized clinical trial.

BACKGROUND AND PURPOSE: Reducing dental anxiety is a major aspect of childmanagement in dental visits. This crossover randomized clinical trial was designed to determine the effect of lavender aromatherapy on anxiety level during dental treatment and pain perception during dental injection in children. MATERIALS AND METHODS: Twenty-four children aged 7-9 years received restorative treatment with lavender aromatherapy in the intervention session and without aroma in the control session. Salivary cortisol and pulse rate were measured to evaluate child's anxiety level and the Face Rating Scale (FRS) was used for assessing the pain perception during injection in both visits. RESULTS: The treatment effect on salivary cortisol, pulse rate, and FRS score was -8.01 ± 0.92 nmol/l, -11.17 ± 1.28 (in minutes), and -2.00 ± 0.41 respectively, which was statistically significant (P < 0.001). CONCLUSION: Lavender aromatherapy can decrease dental anxiety and experienced pain in dental setting.

Effect of music at 432 Hz and 440 Hz on dental anxiety and salivary cortisol levels in patients undergoing tooth extraction: a randomized clinical trial.

Objective The aim of this study was to compare the effects of music at 432 Hz, 440 Hz, and no music on the clinical perception of anxiety and salivary cortisol levels in patients undergoing tooth extraction. Methodology A parallel-group randomized clinical trial was conducted. Forty-two patients (average age: 23.8±7.8 years, 27 women) with a moderate level of anxiety were distributed in three groups: use of music for 15 minutes at a frequency of 432 Hz (n=15), at 440 Hz (n=15) and a control group without music (n=12). The CORAH Dental Anxiety Scale and salivary cortisol levels, estimated by the solid phase enzyme-linked immunosorbent assay (ELISA), were measured and compared before and after the music intervention between groups (two-way ANOVA-Tukey p<0.05, RStudio). Results Significantly lower anxiety level values were observed at 432 Hz (8.7±2.67) and 440 Hz (8.4±2.84) compared to the control group (17.2±4.60; p<0.05). The salivary cortisol level at 432 Hz (0.49±0.37 µg/dL) was significantly lower than 440 Hz (1.35±0.69 µg/dL) and the control group (1.59±0.7 µg/dL; p<0.05). Conclusion The use of music significantly decreased clinical anxiety levels, and the frequency of 432 Hz was effective in decreasing salivary cortisol levels before tooth extraction.

Can lavender oil inhalation help to overcome dental anxiety and pain in children? A randomized clinical trial.

Aromatherapy with essential oils can be used to relieve children. The aim of this study was to evaluate the correlations between psychological and physiologic findings after lavender oil inhalation among children assigned to undergo tooth extraction. A total of 126 children aged between 6 and 12 years were enrolled in the study. The groups were randomly divided into control and lavender groups. The lavender group inhaled 100% lavender oil for 3 min before the interventions, the control group received no prior application. Psychological assessments were made using face image scale (FIS), Face, Legs, Activity, Cry, Consolability (FLACC) and Wong-Baker pain rating scale (WBS). Physiologic changes were assessed using vital signs evaluations. All parameters were noted prior to applications, after inhalation, anesthesia injection, and tooth extraction. The lavender group showed significant lower anxiety and pain scores after tooth extraction (p < 0.05). Significantly lower levels of blood pressures and a significant pulse rate drop were found after inhalation in the lavender group. A statistically significant increase in heart rate was observed after anesthesia injection and tooth extraction in the control group (p < 0.05).Conclusion: Lavender oil can be preferred as a treatment of choice in routine pediatric dentistry.Trial registration number: NCT04115891 (Lavender Oil Inhalation Help to Overcome Dental Anxiety Among Children)What is Known:• Dental anxiety is the most common factor that causes children to have difficulty with the dentist and their parents during treatment.• Aromatherapy with essential oils can be used to relieve children.What is New:• Aromatherapy with lavender oil relieves the child by reducing the level of anxiety and facilitates dental treatment.• During surgical procedures such as local anesthesia and tooth extraction, lavender oil inhalation decreases pain levels of children.
