Background. With five years having passed since the last survey (2002), a new survey was carried out, the 4th since 1987. The aim is to determine the state of oral health of children and adolescents in Navarre and its evolution. Population and methods. The sample (n=1.397) was selected through multistage probability sampling, taking as a unit the classrooms of the 1^st and 6^th year of Primary Education and the 2^nd of Compulsory Secondary Education. The fieldwork was carried out in the months of April and May 2007 by two calibrated teams of examiners. Health variables studied: caries (measured with WHO criterion and extended criterion), periodontal state and malocclusion. The data were computerised with Access XP 2003 SP3; the statistical analysis with SPSS Windows v.15.0. Results. Ten point eight percent of the sample is of foreign origin. The prevalence of caries in temporary dentition at 6 years is 35.9% with a dft of 1.26; in permanent dentition, 28.5% and 46.4% at 12 and 14 years; the average of affected teeth 0.63 and 1.28 respectively. The index of restoration is 26.1% in temporary dentition and 68.9 and 74.1% in permanent; those of foreign origin show more caries (p <0.05) and less treatment (p <0.05) than those of Spanish origin. Sixty-two point eight percent of 14 year olds show gingival bleeding and 16.8%, calculus; 14.7% malocclusion and 19.1% wear orthodontic appliances. Conclusions. Caries are stabilised in temporary dentition in the general population, but fall significantly amongst natives (those of Spanish origin); in permanent dentition they continue their tendency to fall, although more moderately. Navarre is amongst the regions with a lower level of caries and a higher index of restoration. Immigrants show significantly more caries. The index of restoration falls slightly with respect to previous years. The periodontal health figures are poor. Malocclusion and orthodontic appliance wearers are stabilised.
