Early childhood caries: current evidence for aetiology and prevention

Background: Despite the fact that it is largely preventable, dental caries (decay) remains one of the most common chronic diseases of early childhood. Dental decay in young children frequently leads to pain and infection necessitating hospitalization for dental extractions under general anaesthesia. Dental problems in early childhood have been shown to be predictive of not only future dental problems but also on growth and cognitive development by interfering with comfort nutrition, concentration and school participation. Objective: To review the current evidence base in relation to the aetiology and prevention of dental caries in preschool-aged children. Methods: A search of MEDLINE, CINALH and Cochrane electronic databases was conducted using a search strategy which restricted the search to randomized controlled trials, meta-analyses, clinical trials, systematic reviews and other quasi-experimental designs. The retrieved studies were then limited to articles including children aged 5 years and under and published in English. The evidence of effectiveness was then summarized by the authors. Conclusions: The review highlighted the complex aetiology of early childhood caries (ECC). Contemporary evidence suggests that potentially effective interventions should occur in the first 2 years of a child's life. Dental attendance before the age of 2 years is uncommon; however, contact with other health professionals is high. Primary care providers who have contact with children well before the age of the first dental visit may be well placed to offer anticipatory advice to reduce the incidence of ECC.

Body mass index and dental caries in children and adolescents : a systematic review of literature published 2004 to 2011

The objective
The authors undertook an updated systematic review of the relationship between body mass index and dental caries in children and adolescents.
Method
The authors searched Medline, ISI, Cochrane, Scopus, Global Health and CINAHL databases and conducted lateral searches from reference lists for papers published from 2004 to 2011, inclusive. All empirical papers that tested associations between body mass index and dental caries in child and adolescent populations (aged 0 to 18 years) were included.
Results
Dental caries is associated with both high and low body mass index.
Conclusion
A non-linear association between body mass index and dental caries may account for inconsistent findings in previous research. We recommend future research investigate the nature of the association between body mass index and dental caries in samples that include a full range of body mass index scores, and explore how factors such as socioeconomic status mediate the association between body mass index and dental caries.

Protocol for the Hall Technique study: A trial to measure clinical effectiveness and cost-effectiveness of stainless steel crowns for dental caries restoration in primary molars in young children

BACKGROUND: The Hall Technique (HT) is a carious primary molar treatment that does not require local analgesia, carious tissue removal or tooth preparation. The carious lesions in carefully selected teeth are sealed with a stainless steel crown (preformed metal crown). The study aims are to determine the clinical effectiveness, acceptability and cost-effectiveness of the HT for management of carious lesions in young dental patients. METHODS/DESIGN: Children, aged 3-7years, with a primary molar tooth with a carious lesion extending no further than the middle third of dentine, with no signs or symptoms of pulp inflammation or infection, and attending one of three community agencies are recruited. Target sample size is 220. A control tooth with an intra-coronal restoration is sourced from the same mouth. The primary outcome is the period of time free from further treatment. The assessments are scheduled at 6, 12 and 24months. In addition to the clinical assessment, acceptability of the HT will be assessed via questionnaires among patients and their primary carers at baseline, 6, 12 and 24months. Cost-outcome description and cost-effectiveness analysis from healthcare provider and societal perspective will be conducted. DISCUSSION: The clinical effectiveness, acceptability and cost-effectiveness of the HT in the community dental setting will be evaluated. The results of this study will determine the implementation of HT in the management of dental caries in young children.
