ABSTRACT
Objective. To determine the experience, prevalence and severity
of dental caries, as well as the Significant Caries Index
(SiC) and the treatment needs (TN) in schoolchildren aged six
to twelve years. Equally, to estimate the effect of caries in primary
dentition on caries in permanent dentition.
Material
and methods. A cross-sectional study was realized in 3865
schoolchildren from San Luis Potosí City, Mexico. Subjects
were clinically evaluated by three standardized examiners
(kappa › 0.85). For detection of caries was employed the
WHO’s criteria for primary (dmft) and permanent (DMFT)
dentitions. In the statistical analyzes non-parametric test and
logistic regression were used.
Results. Mean of age was 8.69
± 1.79 and 51.3% were women. In the primary dentition: dmft
index was 1.88 ± 2.34 and the caries prevalence (dmft › 0) of
56.8%. In account to severity 22.0% and 5.6% have dmft › 3
and dmft › 6, respectively. In children of six years, the caries
prevalence was 56.0% and the SiC of 5.45. In the permanent
dentition: DMFT index was 1.11 ± 2.03 and the caries prevalence
(DMFT › 0) of 36.8%. In account to severity 11.8% and
2.8% have DMFT › 3 and DMFT › 6, respectively. In children
of twelve years, the DMFT index caries 4.14 ± 4.15 and
the SiC of 9.15. The TN index was of 88.5% for primary dentition
and 93.6% for the permanent. In logistic regression we
observed associated to caries prevalence in permanent dentition;
presence of caries in primary dentition (OR = 6.37; p ‹
0.001), female sex (OR = 1.33; p ‹ 0.001) and higher age (OR
= 1.69; p ‹ 0.001).
Conclusions. Caries prevalence to six
years old and DMFT index to twelve years old were highest to
values established by WHO. Caries severity in the primary
dentition was two times than observed in the permanent den-
tition. High TN in both dentitions was observed. Presence of
caries in primary dentition was a strong risk indicator for to
present caries in permanent dentition.
