The results of brushing for children aged 8–12 years could benefit from

increasing tooth-brushing time. Children could be given an increasing responsibility from 7 to 8 year of age but parental help is motivated up to 10 years of age. “
“International Journal of Paediatric Dentistry 2013; 23: 101–109 Background.  Malnutrition has been consistently associated with caries in primary teeth, although an effect on permanent teeth has not been established because of the few longitudinal studies. Aim.  To explore the association between stunting and caries increment in permanent teeth over 3.5 years. Design.  In 2003, 121 children aged 7–9 years were randomly selected from nine underserved communities in Lima (Peru). Parents provided demographic information and a food diary for Ibrutinib chemical structure their children. Clinical examinations included assessments of height, weight, oral hygiene, learn more and dental caries. Stunting was defined using the 2000 CDC and 2007 WHO standards. In 2006, 83 children were re-examined, and the 3.5-year net DMFS increment was calculated. The association between stunting and net DMFS increment was assessed using negative binomial regression. Results.  Stunting was related to net DMFS increment after adjustment

for sex and age, oral hygiene, sugary snacks between meals, and caries experience in primary and permanent teeth. Consistent results were found when using either the 2000 CDC (incidence rate ratio: 1.61; 95%CI: 1.07, 2.44) or 2007 WHO standards (IRR: 1.79; 95%CI: 1.28, 2.51). Conclusion.  Stunting was a significant risk factor for caries increment in permanent teeth over a 3.5-year period, independent of other well-known risk factors for caries development. “
“International Journal of Paediatric Dentistry 2013; 23: 39–47 Background.  Caries in preschool children remains an important public health issue. Aim.  To determine (i) which teeth and tooth surfaces are most susceptible to dental caries by age 3, (ii) where do caries lesions Liothyronine Sodium develop during 2-year follow-up, and (iii) to

evaluate the impact of caries onset on the distribution of new caries experience. Design.  One thousand and fifty seven consecutively born children were recruited in Flanders (Belgium). Parents completed validated questionnaires on oral health-related behaviour and trained dentists examined the children at ages 3 and 5. Results.  Children with visible caries experience at age 3 were significantly more vulnerable in developing additional caries during follow-up. In this group, new caries experience developed primarily in the occlusal and distal surfaces of the mandibular first molars and the occlusal surfaces of the maxillary second and first molars, whereas in the caries-free group, the occlusal surfaces of both mandibular and maxillary second molars ranked first. Conclusions.  This paper confirms the higher vulnerability for further caries development in those children with caries experience at age 3.
