AIM This was to investigate the incidence of dental caries on the occlusal surface of the first permanent molars of schoolchildren, and also the associated sociodemographic, behavioural and biological risk factors. MATERIALS AND METHODS A three-year longitudinal study on dental caries of the occlusal surface of the first permanent molars was carried out in 224 children between 9 and 11 years ...

Concurrent with the decline in dental caries has been an increase in the prevalence of dental fluorosis, a side-effect of exposure to greater than optimal levels of fluoride during amelogenesis. The mechanisms that underlie the pathogenesis of dental fluorosis are not known. We hypothesize that genetic determinants influence an individual's susceptibility or resistance to develop dental fluoros...

It is generally accepted that three conditions are essential in the oral cavity for dental caries to occur: a suitable microbe, a substrate for the microbe, and a susceptible tooth. Susceptibility or resistance to dental caries is usually thought of in terms of structure, which is determined, for the most part, during calcification. However, it is also plausible that susceptibility to dental ca...

Mrs. Mellanby's work on dental caries, first published in 1918, in which she demonstrated that a sufficient supply of vitamin D was necessary in a child's diet to ensure the metabolism of calcium and phosphorus for the proper formation of the teeth, has had a revolutionary effect on the study of dental caries throughout the world. Her two previous reports, published in 1929 and 1930 respectivel...

The aim of this study was to determine the prevalence of hypoplasia, demarcated opacity and dental fluorosis among schoolchildren with deciduous and permanent dentition. The association between enamel defects and dental caries was also verified. The sample consisted of 624 schoolchildren aged 5 and 309 aged 12. The dmft and DMFT indexes were used to assess dental caries prevalence, DDE to asses...

1. Low-income children experience more dental caries and more complications of caries, such as dental abscesses. Beginning fluoride toothpaste and fluoride varnish during the first year of life can reduce low-income children’s risk of getting dental caries. 2. Pediatricians and other primary care clinicians for children have an important role to play in implementing a dental caries primary prev...

We assessed the inequality in the distribution of dental caries and the association between indicators of socioeconomic status and caries experience in a representative sample of schoolchildren. This study followed a cross-sectional design, with a sample of 792 schoolchildren aged 12 years, representative of this age group in Santa Maria, RS, Brazil. Guardians answered questions on socioeconomi...

This work correlated the presence of oral streptococci in dental biofilm with clinical indexes of caries and oral hygiene in caries-active and caries-free children. S. mutans and/or S. sobrinus in the dental biofilm does not indicate a direct risk for developing dental caries.

It has been suggested that laser fluorescence close to the dental pulp shows higher values than more distant measurements. The aim of this study was to assess fluorescence on the cavity floor and to correlate these measurements with electrical resistance as a measure of residual dentine thickness. Thirty carious lesions were excavated with a bur. The endpoint of caries removal was determined by...

OBJECTIVES To determine the prevalence of dental caries, and associated social risk factors among preschool children in Riyadh, Saudi Arabia. METHODS The study consisted of a random sample of 3 to 5 years- old preschool children who were examined in Riyadh, Saudi Arabia; 388 children (184 boys and 204 girls) were examined from 10 different preschools. Each surface of their teeth was examined ...
