“…Our study included more participants who reported a minimal frequency of gagging in the clinic and a lower level of dental anxiety. The mean level of DFS among the Japanese population is estimated to be 37.4 ± 14.1 . However, the mean scores of the female and male participants in our study were 33.0 ± 14.5 and 28.6 ± 7.8, respectively.…”

A reliable assessment method is required to manage the gag reflex. We tested the inter- and intra-examiner reliability and validity of a quantitative measurement method and evaluated the differences between sexes. This study included 21 healthy adults (10 women, 11 men; mean age, 27.1 ± 9.9 years). An examiner inserted a standard saliva ejector slowly down the participant's throat to determine the maximum tolerance of the gag reflex; the insertion depth was used as an index of gag reflex. The reflex was measured by one examiner during two sessions (S1 and S3) and by a second examiner during one session (S2) under the same conditions. The galvanic skin response (GSR) and heart rate (HR) were recorded during each session to test the method validity. Data were analysed using the intraclass correlation coefficient (ICC), paired t test, and two-way repeated-measures analysis of variance. The ICC of the gag reflex measurements was 0.91 between S1 and S2, and 0.93 between S1 and S3. The GSR and HR increased significantly after the maximum tolerance of the reflex in S1, S2, and S3 (GSR: P < 0.001, P = 0.004, P = 0.001, respectively; HR: all, P < 0.001). Differences in the measurements according to sex and session were not significant. Our method exhibited excellent inter- and intra-examiner reliability and was unaffected by the participants' sex. Measurement revealed significant autonomic reactivity, which is common for this reflex. Consequently, this method may be used in clinical and laboratory-based applications.

“…The level of dental fear was assessed using the dental fear survey (DFS), which consists of 20 questions that address anxiety‐provoking situations associated with dental treatment. The Japanese versions of the psychometric tests were used in this study; the validity and reliability of these tests have been previously verified …”

Objective. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the Dental Fear Survey (DFS), previously translated to the Brazilian Portuguese language and validated. Methods. A cross-sectional study with 1,256 undergraduates from the city of Belo Horizonte, Brazil, was carried out. The DFS and a questionnaire about previous dental experiences were self-administered. Data analysis involved descriptive statistics, principal components analysis (PCA), confirmatory factor analysis (CFA), internal consistency and test-retest reliability, and construct, discriminant, and convergent validity. Results. PCA identified a three-factor structure. CFA confirmed the multidimensionality of the Brazilian version of the DFS. A modified model of the Brazilian version of the DFS fits better than the hypothesized model. The Cronbach's alpha coefficient for the total DFS scale was 0.95. Conclusion. The DFS demonstrated acceptable construct validity, convergent validity, and discriminant validity. These results supported the reliability and validity of the DFS among Brazilian undergraduates.

“…The DFS was cross-culturally adapted and validated among Brazilian psychology undergraduates [19] with higher DFS scores associated with longer intervals between dental visits. The DFS has been translated and validated for application in a range of different countries [10,16,20,21,22,23,24]. Furthermore, the DFS has been used to assess dental fear before dental treatment under sedation, and in the study of dental phobias [10,24].…”

The aim of the present study was to evaluate the association between childhood dental experiences and dental fear in adulthood among dentistry, psychology and mathematics undergraduate students. A cross-sectional study of 1,256 students from the city of Belo Horizonte, Brazil, was performed. Students responded to the Brazilian version of the Dental Fear Survey (DFS) and a questionnaire regarding previous dental experiences. Both the DFS and the questionnaire were self-administered. Association was tested using descriptive, bivariate and multivariate linear regression analysis, with a 5% significance level. Dentistry undergraduates reported lower scores than psychology (p < 0.001) and mathematics undergraduates (p < 0.05) for all three dimensions of the DFS. Negative dental experiences in childhood was associated with dimensions of Avoidance (B = 2.70, p < 0.001), Physiological arousal (B = 1.42, p < 0.001) and Fears of specific stimuli/situations (B = 3.44, p < 0.001). The reason for first visit to dentist was associated with dimensions of Physiological arousal (B = 0.76, p < 0.01) and Fears of specific stimuli/situations (B = 1.29, p < 0.01). Dentists should be encouraged to evaluate the dental fear of their patients before treatment. The DFS has been found to be an effective instrument for this purpose.
