Differences in anxiety, depression, and oral health-related quality of life among dental anxiety patients with and without reported abuse experience.

This study aimed to explore the differences in anxiety, depression, and oral health-related quality of life between people with dental anxiety who reported abuse experience (n = 60) and people with dental anxiety who did not report abuse experience (n = 97). Both groups attended a dental service focused on the treatment of dental anxiety intended for people with a history of physiological or psychological trauma, or odontophobia. The participants responded to a questionnaire that included the Hospital Anxiety and Depression Scale (HADS), Oral Impacts on Daily Performance (OIDP), and the Index of Dental Anxiety and Fear (IDAF-4C+ ). The differences between groups were tested for statistical significance using Welch's T-tests, and linear regression was used to adjust for gender. The participants with reported abuse experience expressed greater psychological symptoms of anxiety and poorer oral health-related quality of life. The participants with reported abuse experience also expressed a higher fear of losing control, as well as feeling shame and disgust. This study shows that individuals with dental anxiety and a history of abuse may face more complex challenges than those with dental anxiety and no history of abuse.

The Abeer Children Dental Anxiety Scale (ACDAS) cross-cultural adaptation and validity of self-report measures in the Malaysian Children Context (MY-ACDAS).

BACKGROUND: The Abeer Children Dental Anxiety Scale (ACDAS) source language was developed and validated in an English-speaking country in the UK to measure dental anxiety among children. The ACDAS also included the child's cognitive assessment, as well as feedback from the parent or the legal guardian and a dental health professional (DHP). This is the first study to validate the application of the ACDAS in Malay or Bahasa Melayu for children aged 6-16 years. AIM: To assess the Malay-translated version of the ACDAS, postadaptation into the local context and validation by the content and construct experts. DESIGN: The English ACDAS was translated into Malay first through forward translation and then through backward translation. The prefinal translated version of the instrument was designed, with the participation of 61 children and 61 parents or legal guardians. Subsequently, a final cross-cultural adaptation of the instrument was then made for another group of participants and evaluated for validity and test-retest reliability among 144 children and 144 parents or legal guardians participating in the self-report feedback process at the Paediatric Dental Clinic, Faculty of Dentistry, Universiti Malaya, Kuala Lumpur, Malaysia. The cross-cultural adaptation of the instrument considered translating to Malaysian national language and adapting to its culture. RESULTS: The Malay-translated ACDAS consisted of 19 items. The translated version of Malaysian-ACDAS (MY-ACDAS) achieved an acceptable agreement between six expert committee members with an internal consistency (Cronbach's alpha value, αconsistency) of 0.839. The test-retest reliability results of all participants support semantic and conceptual equivalence as an accepted construct validity between the children, parents and DHPs across the multicultural Malaysian population. CONCLUSION: The MY-ACDAS is a valid and reliable scale for measuring dental anxiety among Malaysian children.

A study on related factors affecting dental fear in preschool children.

This study aims to examine the manifestations of dental anxiety (DA) and its influencing factors during dental visits among preschool children. The data of 166 preschool children who visited the Department of Dentistry of our hospital from April 2021 to April 2023 with oral problems were retrieved. Their DA performance was investigated using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). In addition, based on their general data and potential risk factor information, we performed logistic regression analysis to identify the factors influencing DA. Of the 166 questionnaires distributed, a total of 160 valid questionnaires were retrieved. The average CFSS-DS score was 35.57 ± 3.51 points. Sixty-six children had DA, resulting in an incidence rate of 41.25%. The top 5 items with the highest CFSS-DS scores were fear of needles, dentists, tooth extraction, drilling and oral anesthesia. When the 66 children with DA were classified into a DA group and a non-DA group, we observed significant differences in age distribution, dental experience, only child status, general anxiety symptoms, dental condition, family income and specific dental treatment procedures, particularly tooth extraction, between them (p < 0.05). Multivariate logistic regression analysis revealed that preschool children aged ≤4 years, those with prior dental experiences, single-child status, general anxiety symptoms, suboptimal dental health, family incomes below 100,000 yuan/year, and those undergoing specific dental procedures, such as tooth extractions, were independently associated with a higher risk of DA (p < 0.05). The incidence of DA in preschool children is high, and they exhibit substantial fear of needles, dentists, tooth extraction, drilling and oral anesthesia. Preschool children aged ≤4 years, with prior dental experiences, single-child status, the presence of general anxiety symptoms, suboptimal dental health, family incomes below 100,000 yuan/year, and those undergoing dental procedures, particularly tooth extraction, could be more predisposed to DA.

Dental clinicians recognizing signs of dental anxiety: a grounded theory study.

INTRODUCTION AND OBJECTIVE: There is a knowledge gap in how dental clinicians recognise dental anxiety. The aim of this study was to identify, describe and generate concepts regarding this process. MATERIALS AND METHODS: Eleven semi-structured interviews were conducted with dental clinicians from the public dental service of Östergötland, Sweden. Purposive and theoretical sampling was used. Theoretical saturation was reached after eight interviews. The interviews were audio-recorded and transcribed verbatim. Classical grounded theory was used to inductively analyse data by constant comparative analysis. RESULTS: The core category was identified as; 'the clinical eye', clinicians noticing behaviours possibly due to dental anxiety based on their knowledge, experiences, or intuition. The core category comprises the five categories: Sympathetic activation, Patient-reported anxiety, Controlling behaviours, Avoidance and Accomplishment. Initially there is usually uncertainty about whether a behaviour is due to dental anxiety or part of a patient's normal behaviour. To gain additional certainty, clinicians need to recognise a stressor as something in the dental setting by observing a change in behaviour, for better or for worse, in the anticipation, presence or removal of the stressor. CONCLUSIONS: Clinicians identify patients as dentally anxious if their behaviour changes with exposure to a stressor.

Turkish version of the faces version of the Modified Child Dental Anxiety Scale (MCDASf): translation, reliability, and validity.

OBJECTIVES: To cross-culturally adapt of MCDASf into Turkish and to evaluate reliability and validity of the Turkish version of MCDASf using explorative factor analysis (EFA), confirmatory factor analysis (CFA), and receiver operating characteristic (ROC) analysis to form a less time consuming and easy to understand tool for measuring dental anxiety. MATERIALS AND METHODS: A total of 300 children (174 females, 126 males) aged 6-12 years who were recruited at the Department of Paediatric Dentistry in RTEU at the first visit participated in the present study. For the internal consistency reliability, Cronbach's alpha was calculated. Intraclass correlation coefficients (ICCs) were calculated for test-retest reliability (n=67). Construct validity was determined by comparing with the Venham Picture Test (VPT). The factor structure was examined using EFA. CFA was used for dimensionality. The cut-off points of the Turkish version of MCDASf were plotted using a ROC curve. RESULTS: The Turkish version of MCDASf showed high internal consistency (0.703) and an excellent ICC value (0.827). Good correlations were found between the global scores of MCDASf and VPT (r=0.632). Three factors were identified from EFA and verified with CFA. Discriminant validity was supported by high scores of females and younger children (p<0.05). The cut-off point was assigned as >24.50. The area under the ROC curve (AUC) was 0.921 (95% CI: 0.873-0.969). CONCLUSIONS: The Turkish version of the MCDASf is a reliable and valid scale that satisfied psychometric properties. CLINICAL RELEVANCE: The Turkish version of MCDASf is a usable tool for the measurement of dental anxiety among Turkish speaking children.

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.

[Diagnosis and treatment of dental anxiety]. / Diagnostiek en behandeling van angst voor de tandheelkundige behandeling.

Fear of dental treatment is a common phenomenon. Every oral health care provider will have to treat a patient with this fear one day. Adequate diagnostics are essential for a correct assessment of the level of fear and how an anxious patient can best be helped. In cases of mild fear, lowering the state anxiety by teaching the patient coping skills, will suffice. In cases of extreme fear, reducing disposition anxiety (the core of the anxiety disorder) comes first, since this will not only reduce fear during the treatment, but will also halt avoidance behavior, which in the end will have a positive effect on the oral health care of the patient.

Patients' multifaceted views of dental fear in a diagnostic interview.

OBJECTIVES: The aim was to examine how patients describe and perceive their dental fear (DF) in diagnostic interviews. MATERIAL AND METHODS: The sample consisted of dentally anxious patients according to the Modified Dental Anxiety Scale (MDAS), who had problems coping with conventional dental treatment. The voluntary participants (n = 7, aged 31-62 years) attended a diagnostic interview aiming to map their DF before dental treatment. The data were analysed by theory-driven qualitative content analysis. The themes consisted of the four components of DF: emotional, behavioural, cognitional, and physiological, derived from the Index of Dental Anxiety and Fear. RESULTS: Within these four themes, treated as the main categories, 27 additional categories related to the patients' interpretations of DF were identified in three contexts: before, during and after dental treatment. 10 categories depicted difficult, uncontrollable, or ambivalent emotions; nine depicted behavioural patterns, strategies, or means; five depicted disturbing, strong, or long-lasting physiological reactions, including panic and anxiety symptoms. The remaining three categories related to cognitive components. CONCLUSIONS: The results indicate that dental care professionals may gain comprehensive information about their patients' DF by means of four component-based diagnostic interviews. This helps them to better identify and encounter patients in need of fear-sensitive dental care. TRIAL REGISTRATION NUMBER: NCT02919241.

Translation and validation of modified dental anxiety scale based on adult Taiwan population.

BACKGROUND: Dental anxiety is associated with negative experiences of dental treatment and dental-visiting behavior. The Modified Dental Anxiety Scale (MDAS) is widely used for assessing dental anxiety. The study aims to establish the psychometric properties of a Chinese version of the MDAS based on the Taiwan sample (i.e., T-MDAS). METHODS: The T-MDAS and dental-visiting behavior and experience were assessed for 402 adult subjects recruited from community and clinical sites. The following psychometric properties were assessed: (a) internal consistency, (b) temporal stability, (c) criterion-related validity (i.e., the association with the score of Index of Dental Anxiety and Fear, IDAF-4C), (d) discrimination validity (i.e., the difference in scores between the subjects with and without a habit of a regular dental visit, and (e) the construct validity from a confirmatory factor analysis (CFA). RESULTS: The T-MDAS showed good internal consistency (Cronbach's α = 0.88) and temporal stability (ρ = 0.69, p < 0.001). The score was significantly correlated with the score of the IDAF-4C (ρ = 0.76, p < 0.001) and differed between subjects who regularly visited a dentist or not, supporting good criterion-related validity and discrimination validity. Results from CFA supports good construct validity. Furthermore, higher dental anxiety was related to the lack of a regular dental visit, feeling pain during treatment, and feeling insufficient skills and empathy of dentists. A higher proportion of high-dental anxiety subjects in female subjects (8.5%), compared to male subjects (5.0%), was noted. CONCLUSIONS: The T-MDAS is a valid tool for assessing adult dental anxiety. The score is highly associated with dental-visiting behavior and experience of dental patients.

Pain perception and dental anxiety during periodontal probing in patients visiting community oral health programme: a cross sectional study.

BACKGROUND: Periodontal probing is one of the basic clinical oral examination procedures. It is carried out to assess the severity of gingival and periodontal disease. The experience of pain during probing may discourage patients. So, this study was conducted to estimate the pain perception and dental anxiety experienced during periodontal probing in patients visiting the community oral health programmes of B. P. Koirala Institute of Health Sciences (BPKIHS). METHODS: A cross-sectional study was conducted among 100 participants of community oral health programmes of BPKIHS. Demographic profile, WHO modified Community Periodontal Index (CPI) 2013, Pain perception via Visual Analogue Scale (VAS Scores) and Short Version of Spielberger State-Trait Anxiety Inventory (STAI) Self-evaluation Questionnaire (Y-6 item) were assessed. Mean ± SD and Spearman correlation for pain and anxiety were computed. RESULTS: Only 10% of the study participants had healthy gingiva and 12% had periodontal pockets. Pain perception and dental anxiety was present in the participants. The participants experienced very little pain (6.75 ± 10.65) during periodontal probing. The overall anxiety score was 13.37 ± 1.81. There was a very weak correlation between the VAS Scores and the anxiety scores of the participants. CONCLUSION: This study concludes that pain perception and anxiety are low during periodontal probing. There was no correlation between bleeding on probing with pain and anxiety among the people visiting community oral health programmes of BPKIHS.

Assessment of dental anxiety and dental phobia among adults in Lebanon.

BACKGROUND: Dental anxiety continues to be a widespread problem affecting adult populations. The primary aim of our study was to evaluate the psychometric properties of the Lebanese Arabic version of the Modified Dental Anxiety Scale (MDAS-A) and to identify the optimal cut-off for assessing dental anxiety and dental phobia among adults in Lebanon. In addition, we sought to assess dental anxiety and phobia as well as their correlates among Lebanese adult patients. METHODS: A cross-sectional study was carried out on a sample of 451 dental adult patients aged between 18 and 65 years old. Information about demographic characteristics, previous bad dental experience, trauma's experience period, perception of a periodontal problem, sensation of nausea during dental treatment, the MDAS-A scale, and the Visual Analogue Scale for anxiety (VAS-A) were collected. RESULTS: MDAS-A exhibited evidence of adequate psychometric properties. The optimal cut-off was 12 for dental anxiety and 14 for dental phobia. Out of the total sample, 31.5% suffered from dental anxiety while 22.4% had a dental phobia. Multivariable analysis showed that the odds of dental anxiety and phobia were higher among females compared to males. Also, patients suffering from periodontal problem perceptions, bad dental experiences during childhood and adolescence, and the sensation of nausea during dental treatment were at a higher risk of developing dental anxiety and phobia compared to their counterparts. However, a higher level of education was found to be a protective factor against dental phobia among Lebanese adult patients. CONCLUSION: The MDAS-A scale is a suitable tool for the routine assessment of dental anxiety and phobia among Lebanese adult patients. Identifying patients with dental anxiety at the earliest opportunity is of utmost importance for delivering successful dental care.

Psychometric evaluation of the Lebanese Arabic version of the Dental Fear Survey: a cross-sectional study.

BACKGROUND: Dental fear is a prevalent problem that can lead to poor dental health. The Kleinknecht's Dental Fear Survey (DFS) is one of the used scales to assess dental fear. The present study aims to evaluate the psychometric properties of the Lebanese Arabic version of the DFS (DFS-A) and to determine the optimal cut-off to identify dental fear as well as the correlates of dental fear in a group of Lebanese adults dental patients. METHODS: A cross-sectional study was conducted among a group of 442 dental patients (18-65 years) recruited at 29 dental clinics from March to June 2019. Patients completed a questionnaire including questions about demographic characteristics, previous bad dental experience, trauma's experience period, the sensation of nausea during dental treatment, the DFS-A scale, the Lebanese Arabic version of the Modified Dental Anxiety Scale (MDAS-A), and a general question about dental fear. RESULTS: DFS-A revealed evidence of adequate psychometric properties. DFS-A scale demonstrated high internal consistency (cronbach's alpha = 0.93). Test-retest reliability assessment demonstrated strong reproducibility of the DFS-A scale score (ICC = 0.92 with 95% CI (0.83-0.96), p value < 0.0001 (N = 30). Confirmatory factor analysis revealed a three-factor structure of the DFS-A reflecting fear associated with specific dental stimuli and procedures, patterns of dental avoidance and anticipatory anxiety, and physiologic arousal during dental treatment. A significant correlation was found between DFS-A and the MDAS-A indicating a good convergent validity. The optimal cut-off point to identify patients with and without dental fear is 41. Considering this cut-off score, the prevalence of dental fear in our sample was reported at 33.8%. Multivariable analysis showed that having previous scary and painful dental experiences, a sensation of nausea during treatment, and having dental anxiety were identified as predictors of dental fear. CONCLUSION: The adapted Arabic version of the DFS (DFS-A) is a valid tool to evaluate dental fear among Lebanese adult patients.

Dental Anxiety Scales Used in Pediatric Dentistry: A Systematic Review and Meta-analysis.

AIM: To assess various dental anxiety scales used in children and to know the effectiveness of different projective dental anxiety scales used in pediatric dentistry. BACKGROUND: Dental anxiety poses a significant problem in child patient management and is considered to be the main barrier for successful completion of the dental treatment. REVIEW RESULTS: This systematic review and meta-analysis has been registered at the International prospective register of systematic reviews-PROSPERO-CRD42021247586. The systematic review was conducted in accordance with the Preferred Reporting Items in Systematic Review and Meta-Analysis (PRISMA) guidelines. Electronic databases [PubMed (MEDLINE), COCHRANE Library, EMBASE, EBSCO host, and Google Scholar database] were searched for corresponding references up to 2021. Observational cross-sectional studies comparing two different dental anxiety scales were selected for this systematic review. Search strategy generated 500 articles out of which 13 studies included in qualitative synthesis and only 7 studies were taken for quantitative synthesis. Among these seven studies, five studies compared FIS and VPT scales, two studies compared RMS, FIS, and VPT scales. Results of meta-analysis showed that an overall mean difference of dental anxiety between VPT and FIS scales was 0.11 (95% CI: 0.26-0.48), RMS and FIS scales was 0.05 (95% CI: 0.40-0.50), RMS and VPT was 0.27 (95% CI: 0.80-0.27) in the investigated population. CONCLUSION: No statistically significant difference was noted in all comparisons suggesting that all these scales are at par in assessing anxiety levels in pediatric population. CLINICAL SIGNIFICANCE: The projective scales Raghavendra, madhuriu, sujata pictorial scale (RMS), Facial image scale (FIS), and Venham's picture test (VPT) can be a pragmatic tool in assessing children's dental anxiety.

Evaluating the validity of the Index of Dental Anxiety and Fear (IDAF-4C+) in adults with severe dental anxiety.

Dental anxiety is a common condition with severe consequences for oral health and health-related quality of life. The aim of this study was to evaluate the recently developed self-report scale Index of Dental Anxiety and Fear (IDAF-4C+) in adults with severe dental anxiety. A sample of 147 adults (age 20-71 yr) with severe dental anxiety completed a questionnaire including the IDAF-4C+ and three other dental anxiety scales. In a clinically assessed subgroup (n = 93), 95% had an International classification of diseases and related health problems 10th version (ICD-10) diagnosis of specific phobia for dentistry. Agreement between the scales was analysed using Spearman's correlation, the Kappa measure of agreement and the intraclass correlation coefficient. The agreement of dental phobia according to the IDAF-4C+ phobia module and the ICD-10 was very low (ĸ = 0.02). The anxiety and fear module of the IDAF-4C+ showed acceptable agreement with the other scales (rs 0.69-0.75; ICC 0.90, 95% CI 0.87-0.93). We conclude that the IDAF-4C+ offers more information to clinicians and researchers than the older dental anxiety scales, but the phobia module needs further development.

The Reliability and Validity of the Japanese Version of the Modified Dental Anxiety Scale among Dental Outpatients.

INTRODUCTION: A careful assessment of dental anxiety is necessary for its management. The Modified Dental Anxiety Scale (MDAS) is one of the most commonly used questionnaires to measure dental anxiety in the world. The reliability and validity of the Japanese version of MDAS have been demonstrated using undergraduates and a few patients with dental anxiety. The aim of the present study was to examine the reliability and validity of the Japanese version of the MDAS using a wide range of age samples in dental clinics. METHODS: A total of 275 outpatients (145 men and 130 women; 21-87 years) from two dental clinics participated in the present study. Dental anxiety was assessed using the Japanese version of the MDAS and the Dental Fear Survey (DFS). The psychometric evaluation included exploratory factor analysis, and Cronbach's α was used to evaluate for internal consistency. Criterion validity was assessed by correlating the MDAS and DFS scores using Spearman's correlation coefficient. validity was evaluated by examining related factors' differences in the MDAS score (e.g., sex and negative dental experiences). RESULTS: Six patients (2.2%) reported high levels of dental anxiety (MDAS score ≥ 19). The internal consistency of the MDAS score was high (Cronbach's α = 0.88). Dental anxiety was significantly higher among women (P=0.007), in patients with previous negative dental experiences (P < 0.001), and among those with lower frequencies of dental visits (P < 0.001). The MDAS score was significant and related to age (r = 0.48) and the DFS score (r = 0.87). Factor analysis revealed all items measured only one construct. CONCLUSIONS: The Japanese version of the MDAS score was found to be a reliable and valid measure of dental anxiety among dental outpatients. It could be useful for the Japanese dental practitioner to measure dental anxiety in a clinical setting.

Children's drawing as a measurement of dental anxiety in paediatric dentistry.

BACKGROUND: Drawings can be used as a method of communication that represents an individual's self-concept, anxiety, attitude or conflict. AIM: The purpose of this study was to evaluate children's drawing as a measure of dental anxiety in a dental setting. DESIGN: Seventy-eight children, aged 6-12 years, were enrolled in this study. Pulp therapy and/or restorative treatment was performed during the first therapeutic session for all participants. Sound, Eye and Motor (SEM) and Frankl scales were used as an objective assessment of behaviour during treatment. After the treatment session, the children were instructed to draw a picture of a person at a dental clinic. Children's drawings were scored by a paediatric dentist and a psychologist using Child Drawing: Hospital (CD: H) scale and emotional indicators of Human Figure Drawings (HFD). The findings were compared with Frankl and SEM scores. RESULTS: There was a significant negative correlation between Frankl and CD: H scores (P = .017), and a significant negative correlation was found between HFD and Frankl scores (P = .048). CONCLUSION: Drawings can reveal a considerable amount of information about children's emotional status, and children's drawing can be a useful non-verbal self-report measure to evaluate anxiety in a paediatric dental setting.

Evaluation of the ability of dental clinicians to rate dental anxiety.

The aim of this study was to evaluate the ability of dental clinicians to rate dental anxiety. A total of 104 clinicians from 24 public dental clinics in the Region of Östergötland, Sweden, examined 1,128 adult patients undergoing their regular dental examination. The patients rated their dental anxiety using the Modified Dental Anxiety Scale and a Visual Analogue Scale. After the examination, the clinicians rated the patients' levels of dental anxiety on a Visual Analogue Scale. The correlation (rs ) between the clinicians' and patients' ratings of dental anxiety was 0.45. Among highly dentally anxious patients, there was no correlation between clinicians' and patients' ratings. Dental clinicians rated dental anxiety lower than their patients did, especially if the patients were highly anxious. The ability of clinicians to rate dental anxiety was better when the clinician was older and the patient was older. There was an inverse association between clinicians' confidence and their ability to rate a patient's dental anxiety. In conclusion, clinicians are unsuccessful in identifying a dentally anxious patient without the concurrent use of patient self-assessment tools. A Visual Analogue Scale is a suitable screening tool in general practice for detection of dental anxiety.

Association of temperament with dental anxiety and behaviour of the preschool child during the initial dental visit.

The aim of this study was to investigate whether there is an association between temperament characteristics of preschool children, dental anxiety, and their dental behaviour. A total of 100 children, aged 3-5 yr, who were attending their initial dental visit accompanied by a parent, were included in this cross-sectional study. Dental anxiety of children was measured using the Facial Image Scale. The behaviour of children during the initial oral examination and oral prophylaxis was assessed using Frankl's behaviour rating scale. Temperament was assessed using Emotionality, Activity, Shyness Temperament Survey for Children (parental ratings). Statistically significant weak linear positive correlations were seen between the following: the percentage duration of definitely negative behaviour and shyness scores (rs  = 0.28); anxiety level and emotionality scores (rs  = 0.28); and anxiety level and shyness scores (rs  = 0.26). Multinomial logistic regression analysis revealed that children with higher anxiety had higher odds of showing definitely negative behaviour, which decreased with increasing age of the child. Emotionality and shyness temperaments may be weakly associated with dental anxiety, and shyness may be weakly associated with the dental behaviour of the preschool child. Definitely negative dental behaviour is associated with dental anxiety and age of the child.

The effect of the waiting room's environment on level of anxiety experienced by children prior to dental treatment: a case control study.

BACKGROUND: In addition to visit purpose, one of the environmental factors that can cause anxiety prior to dental treatment includes the waiting room experience, specifically the amount of time spent awaiting treatment and the waiting room environment. The purpose of this study was to compare the effect of the waiting room's environment on the level of anxiety experienced by children in multisensory and traditional waiting rooms. METHODS: Case control study. Test group waited for treatment in a multisensory waiting room, which consisted of a lighting column that children could touch and climb; as well as, rhythmic music played on loudspeakers. Control group waited for treatment in a traditional waiting room. Study participants were asked to answer the "Venham Picture Test", a dental anxiety scale, while in the waiting room prior to entering the treatment room. Chi-squared, Fisher's Exact tests, and linear regression were utilized. A p-value less than 0.05 was considered statistically significant. RESULTS: No significant difference in dental anxiety scores was found between the test and control groups according to waiting room type (p > .05). Dental anxiety was significantly higher in patients who had longer waiting time prior to treatment (p = 0.019). In addition, dental anxiety was significantly associated with visit purpose (p < .001): children waiting for dental examination or those scheduled for dental treatment with conscious sedation were less anxious than children waiting for emergency treatment. CONCLUSIONS: A sensory adapted waiting room environment may be less important in reducing children's anxiety prior to dental treatment. Children's dental anxiety can be reduced by preventing emergency treatments, scheduling routine dental visits and decreasing waiting time. TRIAL REGISTRATION: TRN NCT03197129, date of registration June 20, 2017.

Single tooth anesthesia versus conventional anesthesia: a cross-over study.

OBJECTIVES: The aim of the present study was to compare an electronic device, the Wand Injection System (Milestone Scientific Livingstone), with conventional anesthesia in terms of the following: pain sensation during anesthetic injection; effectiveness in achieving adequate anesthesia for a complete painless dental treatment; post-operative discomfort; and patient's anxiety toward dental treatment. MATERIALS AND METHODS: Eighty adults from 18 to 70 years were enrolled in this cross-over study. Each patient served as his/her own control being subject to two anesthesia techniques: conventional and Single Tooth Anesthesia (STA) performed with the Wand. A split-mouth design was adopted in which each tooth undergoing conservative restorative or endodontic treatment received anesthesia with both techniques at 1-week interval. Before anesthetic administration, the patients' anxiety levels were determined. Physiological parameteres were measured before, during, and after the two injection procedures, and the Visual Analogue Scale (VAS) was used to assess pain of injection, discomfort, and anesthetic efficacy. Differences in assessment of pain's injection, discomfort, anesthetic efficacy, vital parameters (heart rate, blood pressure, and oxygen saturation), and state anxiety levels were analyzed using Student's t test (p value < 0.001). RESULTS: The mean injection pain and post-operative discomfort ratings with Wand were lower than those with conventional syringe (p = 0.022 and p < 0.001, respectively). No differences were found in the assessment of anesthetic efficacy. Blood pressure and heart rate mean values were lower during the anesthesia performed with the Wand than with the conventional syringe (p < 0.001). The anxiety level was higher during the first appointment, independently from the device used for the injections. CONCLUSION: The STA technique resulted in lower pain, discomfort, and lower intensity of physiological parameters. CLINICAL RELEVANCE: Single Tooth Anesthesia could be an efficacious alternative to conventional procedures.
