Early dental decay of first permanent molars, epidemiological study among school children
Objectives: The aims of this study were
1)To determine the prevalence of dental caries in first permanent molars among school children
2)To Evaluation the DMFT index of first permanent molars.
3)To estimate treatment needs of first permanent molars among school children.
4)To promote oral health.
Methods: 1)It is a cross-sectional study carried out among 540 school children attending public schools in the city of Monastir.
2)Subject selection was achieved using grape sampling method.
3)One lead investigator conducted the clinical examination, other investigators helped with filling the forms.
4) Inclusion criteria:
This study included 3rd, 4th and fifth grade school children aged between 8 and 11 years old
5)Non inclusion criteria:
This study didn't include:
Schoolchildren who are younger than 8 years old and those who are older than 11 years old
Results: Among the children examined during this study, 52.6% had at least one decayed FPM. The mean DMFT index of
FPM of the studied population was 1.41 ± 0.066. Dental caries prevalence was higher at the age of 9 years
with a percentage of 53.4%. Girls were more affected by dental decays than boys with a percentage of
57.9%. Mandibular FPM were more likely to develop caries than their maxillary homologues.
Conclusions: It is necessary to enhance and target the preventive measures undertaken to decrease dental caries among children and to minimize their
