Dental Fear: One Single Clinical Question for Measurement

A new dental fear measurement instrument, the Short Dental Fear Question (SDFQ), was developed and tested for clinical practice purposes. The correlations of the SDFQ with the Dental Anxiety Scale (DAS) and the Dental Fear Survey (DFS) were tested in 15-16-year-old adolescents. The Spearman correlations (rs) between the dental fear measurement instruments were: SDFQ – DFS: rs = 0.79, n = 26; DFS – DAS: rs = 0.72, n = 26; SDFQ– DAS: rs = 0.69, n = 27. DAS and DFS mean scores were clearly higher in the SDFQ fear group than SDFQ in the relaxed group. The SDFQ is a short and compact instrument which might be convenient for the measurement of dental fear in clinical practice

Are people with dental fear under-represented in oral epidemiological surveys?

Background/: Dental phobia is associated with poorer dental attendance so epidemiological surveys requiring participants to undertake a dental examination may result in an under-representation of participants with high dental fear. Method: We compared the dental fear distribution of participants and non-participants in an oral examination component of a national epidemiological survey of oral health. Of 12,606 in-scope dentate people aged 15+ who completed a structured computer-assisted telephone interview (CATI) survey, 5,505 (43.7%) participated in the oral examination. Dental fear was assessed with a single-item measure in the CATI. Results There was a significant difference between the percentages of participants and non-participants who rated themselves as “extremely” afraid, although the absolute difference (1.9%) was small. The association between extreme dental fear and participation was significant (OR = 0.66, 95% CI = 0.56–0.77) in multivariate analyses after controlling for possible confounders. Females with extreme dental fear were also significantly less likely to undertake an oral examination. Conclusion: Even though people with dental fear and phobia may delay or avoid dental visits, they do not appear to be appreciably under-represented in oral epidemiological surveys.Jason M.

Early probiotic supplementation and the risk of celiac disease in children at genetic risk

Abstract Probiotics are linked to positive regulatory effects on the immune system. The aim of the study was to examine the association between the exposure of probiotics via dietary supplements or via infant formula by the age of 1 year and the development of celiac disease autoimmunity (CDA) and celiac disease among a cohort of 6520 genetically susceptible children. Use of probiotics during the first year of life was reported by 1460 children. Time-to-event analysis was used to examine the associations. Overall exposure of probiotics during the first year of life was not associated with either CDA (n = 1212) (HR 1.15; 95%CI 0.99, 1.35; p = 0.07) or celiac disease (n = 455) (HR 1.11; 95%CI 0.86, 1.43; p = 0.43) when adjusting for known risk factors. Intake of probiotic dietary supplements, however, was associated with a slightly increased risk of CDA (HR 1.18; 95%CI 1.00, 1.40; p = 0.043) compared to children who did not get probiotics. It was concluded that the overall exposure of probiotics during the first year of life was not associated with CDA or celiac disease in children at genetic risk
