Aim.  The aim of this study was to evaluate soda, juice, sugared-beverage intake, brushing habits, and community water source availability as they relate to the prevalence of both noncavitated and cavitated caries lesions

in small rural villages in Mexico. Design.  The International Caries Detection and Assessment System (ICDAS) was used in children from small, isolated, villages in Mexico. Risk factors were assessed via questionnaires. Results.  Caries prevalence in the villages was very high, ranging from 94.7% to 100% of the children studied. The mean number of surfaces with lesions per child (D1MFS + d1mfs) having scores ≥1 (noncavitated and cavitated) ranged from 15.4 ± 11.1 to 26.6 ± 15.2. Many of the children reported drinking beverages check details containing

sugar. Conclusions.  Drinking sugared beverages, poor oral hygiene habits, and lack of access to tap water were identified as risk factor for caries in this sample of residents of rural Mexico. “
“International Journal of Paediatric Dentistry RGFP966 nmr 2011; 21: 241–248 Objective.  The aim of this study was to clinically assess the effectiveness of masking white spot enamel lesions using a resin infiltration technique that was recently developed to arrest incipient caries in a micro-invasive concept. Methods.  Twenty teeth with a Developmental Defect of Enamel (DDE) and 18 teeth with Post-orthodontic Decalcification (POD) were selected and treated with resin infiltration. Standardized photographs were taken before, immediately after, and 1 week after treatment and were analysed using image analysing software to calculate the ΔE values. The results were classified into three groups: completely masked, partially masked, and unchanged. Results.  Among the 20 teeth with DDE, five teeth (25%) were classified as completely masked, whereas seven

(35%) and eight teeth (40%) were partially masked and unchanged, respectively. Among the 18 teeth with POD, 11 teeth (61%) were completely masked, six teeth (33%) were partially Methisazone masked, and one tooth (6%) was unchanged. In some teeth, the result was more improved after 1 week than immediately after infiltration. Conclusion.  The masking effect was dramatic in some cases but not in others. The long-term colour stability of the result should be followed up through continuous clinical and scientific studies. “
“International Journal of Paediatric Dentistry 2013; 23: 125–130 Background.  Few prospective studies on the anxiety of children in the dental office have been published. Aims.  To monitor dental anxiety levels in children with and without previous experience with toothache over a period of six consecutive visits. Design.  A longitudinal study was carried out involving 167 children treated at a public dental service.
