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.

“…DFS was initially established in the English language and authors have revealed good psychometric properties supporting its validity and reliability among adults in the USA [ 4 , 5 ]. Due to the influence of linguistic and cultural differences, DFS was translated and adapted to several languages including Indian [ 6 ], Greek [ 7 ], Japanese [ 4 , 8 , 9 ], Korean [ 10 ], Norwegian [ 11 ], Hungarian [ 12 , 13 ], Brazilian [ 14 , 15 ], Turkish [ 16 ], Chinese [ 17 ], and Malay [ 18 ]. The DFS was also translated and validated in the Arabic language by Alamri et al and its psychometric properties were assessed in a sample of 12–15 year Saudi school students in Riyadh [ 19 ].…”

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.

“…The relationship between dental pain and dental fear was studied using Japanese DFS scale in 1988 [ 11 ]. The Korean version of the Dental Fear Scale (K-DFS) was translated and evaluated by Kim et al [ 12 13 14 15 ]. According to Shim et al [ 16 ], the dental fear anxiety scale, a tool used to measure dental fear, was used to distinguish dental fear as dental associative fear and dental fear secondary to age and indirect pain [ 17 ].…”

BackgroundThis study is aimed to evaluate the level of fear and to reduce the overall fear, thereby enabling patients to receive treatment via timely visits.MethodsIn a survey conducted by 460 South Korean middle school students, we used 453 data that faithfully responded to the survey. Multiple regression analysis was conducted to investigate the factors influencing subjective oral health and dental fear. The significance level used for statistical significance was α = 0.05.ResultsThe level of fear was higher for upper grade, female students. The factors affecting dental fear were higher for gingival bleeding and dental pain. Regarding factors for dental fear affecting subjective oral health, lower fear of puncture needle and tooth removal tool resulted in higher subjective oral health.ConclusionThe study found that adolescents had higher fear of dental care when they had gingival bleeding and tooth pain. Gingival bleeding is a symptom of early gingival disease and dental pain is likely due to advanced dental caries. These results suggested that it is necessary to have a program to reduce dental fear and anxiety as well as a program to prevent dental diseases through regular periodic screening and education.
