Determining Cut-Off Points for the Dental Fear Survey

Patient-related predictors of post-operative pain following root canal treatment: A structural model analysis

AIM

The pathways to post-operative pain are complex and encompass factors that extend beyond the treatment protocol employed. This study aimed to identify patient-related predictors of post-operative pain following root canal treatment.

METHODOLOGY

A total of 154 patients received a single-visit root canal treatment for asymptomatic necrotic mandibular molars. Before treatment, dental anxiety, dental fear and sense of coherence (SOC) were measured as predictors for each patient using validated questionnaires. Other measured predictors included gender, age, previous negative experiences at the dental offices and prior root canal treatment. Post-operative pain was assessed using the Numeric Rating Scale at multiple time-points over 30 days. Structural equation analysis was employed to evaluate the direct and indirect effects of patient-related predictors on a theoretical model of post-operative pain. The irrigant solution was also included in the model, as it was the only aspect that varied in the treatment protocol (sodium hypochlorite 2.5% and 8.25%).

RESULTS

Dental anxiety (coefficient 0.028; p < .01), dental fear (coefficient 0.007; p = .02) and irrigant solution (coefficient 0.004; p = .03) exerted a direct effect on post-operative pain. SOC exerted an indirect effect on post-operative (coefficient 0.006; p = .01) through dental anxiety and dental fear. Moreover, previous negative experiences (coefficient 0.048; p = .04) exerted an indirect effect on post-operative pain through dental anxiety.

CONCLUSIONS

Dental anxiety, dental fear, previous negative experiences and SOC are patient-related predictors of post-operative pain following root canal treatment. These factors should be taken into consideration in clinical practice, as patients with these characteristics may be at an increased risk of experiencing post-operative pain.

A study protocol for a single-centred randomized trial to investigate the effect of pre-treatment communication methods on dental anxiety among adult dental patients

Objective

Optimal oral health is an essential component of good quality of life. However, this may be hindered by dental anxiety (DA), thereby, affecting the utilization of dental services. DA could be alleviated by pre-treatment information; however, the method of delivering this information is yet to be explored. It is, therefore, necessary to assess the modes of presenting pre-treatment information to ascertain the one with significant effect on DA. This will improve treatment outcomes and quality of life for individuals. Hence, the primary objective is to assess the effect of audiovisual and written forms of pre-treatment information on DA, while the secondary objective will compare the subjective and objective methods of assessing DA with psychometric anxiety scale (Index of Dental Anxiety and Fear (IDAF)-4C+) and salivary alpha-amylase respectively.

Study design

Single-centred, single-blind, parallel-group, four-arm randomized clinical trial.

Methods

The study will compare the effects of audiovisual and written forms of pre-treatment information on DA among adults. Patients 18 years and above scheduled for dental treatment will be screened for eligibility. Written informed consent will be sought before participation. Participants will be allocated randomly using block randomization, to the groups; G1: audiovisual and G2: a written form of pre-treatment information. At the visit, participants will complete the DA questionnaires (IDAF-4C+, Modified Dental Anxiety Scale and Visual Analogue Scale). Physiological anxiety-related changes of salivary alpha-amylase will be measured using a point-of-care kit (iPro oral fluid collector) at baseline, and 10 min after intervention. Furthermore, blood pressure will be taken at baseline and 20 min into the treatment. The mean changes of physiologic anxiety levels and 95% confidence intervals will be compared between the methods of pre-treatment information.

Discussion

This study hopes to establish pre-treatment information as a method for reducing DA among the populace. Also, to assess the relationship between questionnaire-based and physiologic methods of assessing DA.

Fear among Syrians: A Proposed Cutoff Score for the Arabic Fear of COVID-19 Scale

COVID-19 pandemic has led to psychological health issues one of which is fear. This study validates the Arabic version of the fear of COVID-19 scale and suggests a new cutoff score to measure fear of COVID-19 among the Syrian Population. A total of 3989 participants filled an online survey consisting of socio-demographic information, the fear of COVID-19 scale, the patient health questionnaire 9-item, and the generalized anxiety disorder 7-item. Receiver operating characteristic analysis was used to define cutoff scores for the fear of COVID-19 scale in relation to generalized anxiety disorder 7-item and the patient health questionnaire 9-item. The Cronbach α value of the Arabic fear of COVID-19 scale was 0.896, revealing good stability and internal consistency. The inter-item correlations were between [0.420–0.868] and the corrected item-total correlations were between [0.614–0.768]. A cutoff point of 17.5 was deduced from the analysis. According to the deduced cutoff point, 2111(52.9%) were categorized as extreme fear cases. This cutoff score deduced from this study can be used for screening purposes to distinguish community members that may be prone to developing extreme fear of COVID-19. Therefore, early preventive and supportive measures can then be delivered.

Reliability and Validity of the Dental Anxiety Question Used With Children

OBJECTIVE

Dental fear screening is an important part of providing a positive pediatric dental experience. To improve efficiency, the development of a single-item dental fear assessment tool for children has been desired. In this psychometric analysis, the reliability and validity of the Dental Anxiety Question (DAQ) is studied when used in children aged 7 to 18 years.

METHODS

Participants completed the DAQ (pre-tx-DAQ), the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS), and a demographic information questionnaire before treatment. Participants repeated the DAQ after treatment (post-tx-DAQ) and once more at least 2 weeks later (follow-up-DAQ). Stability reliability within the DAQ scores and criterion validity with the CFSS-DS were evaluated.

RESULTS

Stability reliability analyses between pre-tx-DAQ/post-tx-DAQ and post-tx-DAQ/follow-up-DAQ demonstrated significant positive correlations: Spearman rank correlation coefficient (rs) = 0.420, rs2 = 0.18, P &lt; .001, and rs = 0.563, rs2 = 0.32, P &lt; .001, respectively. Criterion validity analysis between the pre-tx-DAQ and CFSS-DS also demonstrated a significant correlation: Pearson correlation coefficient (r) = 0.584, r2 = 0.34, P &lt; .001.

CONCLUSION

The stability reliability and criterion validity of the DAQ was proved among children.

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 Fear and Patient Preference for Emergency Dental Treatment Among Adults in COVID-19 Quarantine Centers in Dammam, Saudi Arabia

PURPOSE

Dental fear is associated with the avoidance of dental visits and negative oral health outcomes. It is important to assess distribution of dental fear and preference for emergency dental treatment among adult population during COVID-19. Therefore, the purpose of this study was to evaluate dental fear and emergency dental treatment among adults in COVID-19 quarantine centers in Greater Dammam, Saudi Arabia.

MATERIALS AND METHODS

Male and female adults (N=606) in quarantine centers for COVID-19 participated in this cross-sectional study (June-July 2020). Dental Fear Survey was used to collect data on dental fear. The participants also provided their responses about emergency dental treatment/dental attendance patterns in addition to demographic information.

RESULTS

The mean DFS score of the sample was 39.08 ± 19.47, and 23.1% of the participants were a little fearful and 22.6% were highly fearful. About 36.8% reported that they would prefer to visit a dental office in case of dental emergency mostly for dental pain and fractured tooth during the COVID-19 pandemic. Only 10.4% of the participants reported visiting a dentist in less than 3 months, 35.8% in less than 6 months, 52.5% between 6 and 12 months and more, and 1.3% never visited the dentist. DFS scores significantly differed among participants who visited the dentist in less than 3 months (31.86 ± 14.57), less than 6 months (37.70 ± 18.57), between 6 and 12 months and more (40.78 ± 20.23), and never visited the dentist (65.75 ± 14.74) (P < 0.001). The timing of last dental visit (P < 0.001), female gender (P 0.039), and dental pain (P < 0.001) were the significant predictors of dental fear.

CONCLUSION

Dental fear was common among adults with a predilection for the female gender. Increased dental fear was significantly related to dental pain and reduced dental attendance. Only one-third of adults were willing to perform emergency dental visits.

Mental Health Screening for COVID-19: a Proposed Cutoff Score for the Greek Version of the Fear of COVID-19 Scale (FCV-19S)

The COVID-19 pandemic elicited fear. The Fear of COVID-19 Scale (FCV-19S) is a newly developed self-reported measure, originally developed in Persian to assess COVID-19-related fear. To date, the scale has been translated and validated in 19 other languages, among which Greek. This study, conducted through an online survey, aimed to further explore the validity of the Greek FCV-19S version, as well as to identify appropriate cutoff scores. A total of 538 respondents completed the sociodemographic data sheet, the Generalized Anxiety Disorder 7-item scale, the Short Health Anxiety Inventory, and the Posttraumatic Stress Disorder-8 inventory. According to the results, a cutoff point score of 16.5 or higher revealed a significant predictive power for anxiety, health anxiety, and posttraumatic stress symptoms. Altogether, although the cutoff scores of the Greek FCV-19S version were explored to further evaluate the scale's validity, they may facilitate discrimination of adults with extreme COVID-19-related fear from those with normal fear reactions.
