Background. Caries is a multifactorial disease and is considered a public health problem because 95% of children worldwide suffer from it. It is intimately associated with oral hygiene quality. The objective of this work was to determine the relationship between the experience of dental caries and oral hygiene in school-age children living in Yautepec, Morelos, Mexico. Methods. A cross-sectional study of 771 school-age children with mixed dentition in Yautepec, Morelos, Mexico was undertaken. An oral exam was used to collect data on oral hygiene and dental caries in primary and permanent teeth. This evaluation was developed by two dentists using standardized DMFT/dmft index to determine dental caries according to the criteria established by the WHO (Cr =0.03, Ca =0.89, k =0.942). Results. The average experience of dental caries was a trend of approximately two primary teeth with some experience of caries and in secondary dentition the average was almost zero. In both cases these differences were found to be statistically significant ( p <0.0001). It was also noted that the disease had no relationship with gender ( p >0.05) but was related with the quality of oral hygiene ( p =0.0001). Conclusions. The average experience of dental caries in both dentitions was low. The condition most frequently observed in terms of quality of oral hygiene was good. The average experience of dental caries was shown to be associated with age and quality of oral hygiene.
