ABSTRACT
Introduction: The World Health Organization reports that tooth decay in Mexico affects 48% of children under 5 years of age and 93% of children under 15. Overall it is estimated that 99% of the population has had tooth decay and that this disease is the most important cause of tooth loss before age 35. The greatest loss is of the first permanent molars, these dental organs represent the primary dentition in the mouth of a child, transforming with its presence the primary occlusion in mixed. Therefore, the purpose of this study was to identify the prevalence and some risk factors for tooth decay in the first permanent molar in a school community in the municipality of Tultitlan, State of Mexico. Methods: An observational, prolective, transverse and descriptive study in a population of 560 students with a mean age of 9.0 (± 2.0), median of 9.0 (6-12 years), the presence of dental plaque (biofilm) was assessed with the O’Leary index and the experience of tooth decay with the DMFT and DMF indexes. Results: The prevalence of tooth decay in the first permanent molar in the study population was 25.6%, the value of the DMF index was 1.6 ± 2.7; DMFT of 1.0 ± 1.4; the most affected were the lower molars with 30.6% (n = 343) with a DMF 1.0 (± 1.7) vs. the upper ones with 20.5% (n = 226) with a DMF of 0.6 (± 1.4). Of the risks analyzed, the factor «time of exposure to PDB» measured through age showed that, schoolchildren ≥ 8 years of age are 7.1 times more likely to have tooth decay in the first molar than children under that age, this difference is clinically and statistically significant (RM = 8.1, IC95% 4.4-14.7, p ‹ 0.0001). Conclusions: Our study population shows a similarity in the tooth decay indexes in permanent dentition with the one indicated in the scientific literature; of the risks analyzed, the exposure time to dental plaque (biofilm) was the one that showed a statistically significant difference.REFERENCES
