ABSTRACT
An epidemiological survey was carried out in 1992 to study the dental health status of schoolchildren aged 6, 9 and 12 in Asturias, Spain. It focused on the caries prevalence, dmtf, DMFT, restoration indices and dental treatment needs of this population. A representative sample of 1839 subjects, randomly selected and proportionally assigned by age group (6, 9 and 12) with the classroom as the sample unit, was examined. Analysis of the data showed that in 6-year-old children the caries prevalence in primary teeth was 45.8%. The mean caries indices were 2.10 dmft and 0.25 DMFT. At 9 years old the prevalence of caries in primary teeth was 62.8% and in the permanent teeth 49.1%. The mean level of caries was 2.38 dmft and 1.50 DMFT. At 12 years old the caries prevalence in permanent teeth was 71% and in first molars 64.2%. The mean caries experienced was 3.30 DMFT. In all groups the D-component constituted the major part of the caries index. The results for girls were higher than for boys in almost all age groups. Surface fillings were the treatment most required in all age groups.

The article describes a new technique for fabricating a wedge directly in the mouth during clinical procedures. It is called a passive wedge because it is kind to the soft tissues, exerting neither compression nor traction on them. A conventional rigid wedge may hurt the interdental papilla, initiating bleeding and the flow of fluids through the rubber dam. This new technique is very useful during adhesive procedures, because the wedge prevents moisture from invading the working area and the cavity, maintains the matrix in place, and causes no harm to the soft tissues, allowing the restoration to be finished properly.

An epidemiological survey was carried out in 1992 researching dental caries and treatment needs in an adult population in Oviedo, Spain. A representative sample of 261 subjects, randomly obtained and stratified by age, was examined. Results show a dental decay prevalence of 99.6%; 12.5 DMFT index with 2.9, 7.5 and 2.1 mean values for D, M and F components. Women and the lower social class showed the highest DMFT index. Treatment needs reach a mean value of 12.1 teeth per person. Pontics are the most needed treatment, the mean value increases with age while the differences among age groups and social classes are statistically significant. The next most needed dental treatment is filling of one surface which decreases with age, is the same for men and women and higher among the middle social class; the differences are statistically significant among the social classes.
