[Prevalence of dental caries: comparison between immigrant and autochthonous children].
INTRODUCTION: Immigration to Spain has been high in recent years, especially in some autonomous communities. In both deciduous and permanent teeth, immigrant children have a higher number of dental caries and a lower number of restored teeth than autochthonous schoolchildren. Few studies have compared the prevalence of dental caries between immigrant and autochthonous children. OBJECTIVE: To determine the prevalence of dental caries in two groups of children: an immigrant group and an autochthonous group. MATERIAL AND METHOD: The study sample consisted of 600 children (235 immigrant children and 365 autochthonous children) aged between 6 and 10 years old who were living in the autonomous community of Valencia. The children were examined by two specialists, an odontologist and a pediatrician. RESULTS: The prevalence of dental caries was higher in immigrant children than in autochthonous children. In deciduous dentition, the prevalence of caries was 47.23 % and 32.05 % in immigrants and autochthonous children, respectively. In permanent dentition, the prevalence was 53.19 % and 35.34 %, respectively. CONCLUSIONS: The prevalence of dental caries was higher in immigrant children than in autochthonous children. Pediatricians and/or odontologists should aim to improve knowledge of good dental health care and habits among immigrant children and their parents.
