These aetiological factors associated with childhood

dental caries need to be investigated further in longitudinal clinical trials. “
“The aim of this retrospective study was to quantify the level of dental developmental delay in a group of patients with Aperts syndrome when compared to matched controls. Twenty-six Dental Panoramic Tomographic (DPT) radiographs of patients with Apert syndrome attending Great Ormond Street Hospital were compared to controls (n = 29) from the Eastman Dental Hospital, UK. Dental development was assessed using the staging systems of Demirjian and Haavikko, and dental age (DA) was estimated using the weighted averages method. Dental age, as estimated using the 12 stages of Haavikko and eight stages of Demirjian, suggested no statistical evidence of developmental delay between the Aperts and control group. The hypothesis AZD6244 ‘that there is no difference in the dental development of subjects with Apert syndrome, when compared to a group of matched controls’, was accepted. “
“The Children’s Fear Survey Schedule-Dental Subscale (CFSS-DS)

is a commonly used questionnaire that measures children’s dental fears. This study aimed to examine GSK126 the reliability and validity of the Chinese version of the CFSS-DS. The CFSS-DS was translated into Chinese and administered to children in a dental office. The sample comprised 206 child patients aged 6–10 years, 42 of whom were selected for test–retest analysis. The behaviors of all

206 children were rated during their dental appointments and compared to their questionnaire results. The internal consistency (Cronbach’s α) was 0.85, and the test–retest reliability (intraclass correlation) was 0.71. The Chinese version of the CFSS-DS showed good criterion validity; children who were uncooperative on the Frankl Scale had higher mean CFSS-DS scores (Z = 5.79). Through factorization, three factors emerged: (1) dental treatment, (2) hospital personnel, and (3) invasive dental procedures. Girls reported more fear than boys (21.79 vs 19.91), and children who had painful Thiamine-diphosphate kinase dental experiences reported more fear (30.87 vs 20.00). These results suggest that the CFSS-DS is reliable and valid and operates in China as it does in other cultures. Further studies should include school samples to evaluate children who may not go to the dentist. “
“International Journal of Paediatric Dentistry 2013; 23: 173–179 Background:  Studies on the prevalence of enamel defects in the primary dentition as a whole are scarce, as most investigations examine specific population groups. Objectives:  The aim of this study was to evaluate the prevalence of enamel defects in primary teeth and determine whether prematurity, birthweight, and socio-demographic variables are associated with such defects. Design:  A cross-sectional study was carried out with 381 children aged 3–5 years.
