Dental pulp stem cells and growth factors incorporated in chitosan hydrogel are able to regenerate pulp- dentine like tissue and help in complete root maturation of non-vital immature permanent teeth with apical periodontitis in dogs.
BackgroundEarly recognition of dental fear is essential for the effective delivery of dental care. This study aimed to test the reliability and validity of the Arabic version of the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS).MethodsA school-based sample of 1546 children was randomly recruited. The Arabic version of the CFSS-DS was completed by children during class time. The scale was tested for internal consistency and test-retest reliability. To test criterion validity, children’s behavior was assessed using the Frankl scale during dental examination, and results were compared with children’s CFSS-DS scores. To test the scale’s construct validity, scores on “fear of going to the dentist soon” were correlated with CFSS-DS scores. Factor analysis was also used.ResultsThe Arabic version of the CFSS-DS showed high reliability regarding both test-retest reliability (intraclass correlation = 0.83, p < 0.001) and internal consistency (Cronbach’s α = 0.88). It showed good criterion validity: children with negative behavior had significantly higher fear scores (t = 13.67, p < 0.001). It also showed moderate construct validity (Spearman’s rho correlation, r = 0.53, p < 0.001). Factor analysis identified the following factors: “fear of invasive dental procedures,” “fear of less invasive dental procedures” and “fear of strangers.”ConclusionThe Arabic version of the CFSS-DS is a reliable and valid measure of dental fear in Arabic-speaking children. Pediatric dentists and researchers may use this validated version of the CFSS-DS to measure dental fear in Arabic-speaking children.
BackgroundDental fear has not only been linked to poor dental health in children but also persists across the lifespan, if unaddressed, and can continue to affect oral, systemic, and psychological health. The aim of this study was to assess the factor structure of the Arabic version of the Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS), and to assess the difference in factor structure between boys and girls.MethodsParticipants were 220 consecutive paediatric dental patients 6–12 years old seeking dental care at the Faculty of Dentistry, King Abdulaziz University, Saudi Arabia. Participants completed the 15-item Arabic version of the CFSS-DS questionnaire at the end of the visit. Internal consistency was assessed using Cronbach’s alpha. Factor analysis (principal components, varimax rotation) was employed to assess the factor structure of the scale.ResultsThe Cronbach’s alpha was 0.86. Four factors with eigenvalues above 1.00 were identified, which collectively explained 64.45% of the variance. These factors were as follows: Factor 1, ‘fear of usual dental procedures’ consisted of 8 items such as ‘drilling’ and ‘having to open the mouth’, Factor 2, ‘fear of health care personnel and injections’ consisted of three items, Factor 3, ‘fear of strangers’, consisted of 2 items. Factor 4, ‘fear of general medical aspects of treatment’, consisted of 2 items. Notably, four factors of dental fear were found in girls, while five were found in boys.ConclusionsFour factors of different strength pertaining to dental fear were identified in Arabic-speaking children, indicating a simple structure. Most items loaded high on the factor related to fear of usual dental procedures. The fear-provoking aspects of dental procedures differed in boys and girls. Use of the scale may enable dentists to determine the item/s of dental treatment that a given child finds most fear-provoking and guide the child’s behaviour accordingly.Electronic supplementary materialThe online version of this article (doi:10.1186/1472-6831-14-118) contains supplementary material, which is available to authorized users.
