Half of the children were involved in a supervised toothbrushing programme...

Objective: The objective of this study was to compare the ICDAS-II caries status and caries-related factors among children from rural and urban schools in Pasto, Colombia. Materials and Methods: The study included 120 children (4 - 6 year- old children) from rural (privileged) and urban (unprivileged) schools. Caries was evaluated using the ICDAS-II criteria. A survey about the factors related to the presence of caries was applied. Chi-square and Fisher's tests were used to assess the differences in each study variable between the two groups...

BACKGROUND: While associations between salivary characteristics and dental caries have been well studied, we are not aware of this being assessed in a remote Indigenous child population, where lifestyles may be different from urban children. Our aim was to assess associations between caries experience and putative biomarkers in saliva, accounting for oral hygiene and dietary habits. METHODS: Children attending schools in an Indigenous community in remote north Queensland, Australia were invited to an oral examination by qualified and calibrated examiners...

BACKGROUND: The shortage of food based feedstocks has been one of the stumbling blocks in industrial biomanufacturing. The acetone bioproduction from the traditional acetone-butanol-ethanol fermentation is limited by the non-specificity of products and competitive utilization of food-based substrates. Using genetically modified Escherichia coli to produce acetone as sole product from the cost-effective non-food based substrates showed great potential to overcome these problems. RESULTS: A novel acetone biosynthetic pathway were constructed based on genes from Clostridium acetobutylicum (thlA encoding for thiolase, adc encoding for acetoacetate decarboxylase, ctfAB encoding for coenzyme A transferase) and Escherichia coli MG1655 (atoB encoding acetyl-CoA acetyltransferase, atoDA encoding for acetyl-CoA: acetoacetyl-CoA transferase subunit α and β)...

OBJECTIVES: Decamarcated hypomineralised lesions of enamel include those developmental defects that are related to MIH, HSPM or any other demarcated opacities of systemic origin. The present study's aims are to determine MIH/HSPM prevalence, caries lesion severity and their association in a sample of 6-12-year-old schoolchildren from Talca, Chile. METHODS: The sample (N = 577) was derived from selected primary schools in urban Talca. A full dental examination was performed at the school by one calibrated examiner...

OBJECTIVES: Discriminating non-cavitated from cavitated proximal lesions without tooth separation is only limitedly possible using visual-radiographic assessment alone. We evaluated how additional tactile assessment might increase the accuracy of this discrimination in vitro. METHODS: Surface integrity of 46 primary molars with proximal lesions extending radiographically into outer third of dentin (ICDAS-codes: 2 n = 34, 3 n = 8 and 5 n = 4) were mounted in groups of two in manikin heads and independently assessed by three examiners using visual-radiographic and additional tactile assessment using a cow-horn-ended explorer with or without gingival displacement...

Data sourcesPubMed, Scopus and Embase were searched from 2000 to 2016.Study selectionA search strategy was developed to identify randomised clinical trials, cross-sectional studies, cohort studies, comparative studies, validation studies and evaluation studies that tested standardised caries risk assessment (CRA) models. There was no restriction with respect to patients' age, but caries data should have been recorded using the Decayed, Missing, Filled Tooth/Surface (DMFT/S) or the International Caries Detection and Assessment System (ICDAS) indices...

OBJECTIVE: Tdescribe the bacterial profile of the supragingival biofilm of children with temporary dentition (CTD) and early mixed dentition (CEMD), with the next-generation sequencing (HOMINGS) technique.
