Impact of hypomineralized teeth and sociobehavioral aspects on caries development: a prospective cohort study|
Silva, Cristiane Maria da Costa; Ambrosano, Glaucia Maria Bovi & Mialhe, Fábio Luiz
Aim: This prospective cohort study was to evaluate the independent and mutual effects of
socioeconomic, oral health behaviors and individual clinical factors, including enamel
hypomineralization, as possible risk factors for increase in caries experience in second primary
molar (SPM) over a period of 2-years.
Methods: Children (n=216) aged 4-6 years were
examined for hypomineralized second primary molar (HSPM) and dental caries in school settings
and were recalled every 6 months. The caregivers filled out a semi-structured questionnaire
about their socio-demographic and oral health-related behaviors. Data analysis was performed
using a hierarchical model with three levels. Multiple analyses were performed at each level and
variables with p<0.20 were tested by stepwise multiple Generalized Estimating Equation.
At final examination, 33.3% of the children had developed new caries lesions in SPM. The model
showed that the number of years of mother’s schooling and the caregiver´s perception about their
children’s caries experience played a protective role in the incidence of dental caries. Children
who had white spot lesions were more likely to develop new carious lesions in SPM. Children
with HSPM showed no higher incidence of caries in their SPM than those without HSPM.
Conclusions: Clinical, socioeconomic and behavioral factors impacted on caries development
in primary second molars. However, further studies are required to better understand the role of
HSPM in caries development in other age groups.
