| dc.description.abstract | ECC (Early Childhood Caries) is a major global problem affecting millions of preschool
children worldwide. ECC not only affects the teeth but also the consequences of this
disease can cause more problems in the health of the child. One of the issues that has been
less addressed in the field of ECC is the study of the effect and relationship between early
childhood caries and its different intensities on the development rate of lower permanent
tooth buds (and consequently the child's dental age). And since understanding this
relationship can further highlight the importance of oral health of the child even during
milk dentition, and the awareness of parents and medical staff about the impact of
premature caries on the child's dental development, help them maintain better oral health
and Prompt treatment of dental caries In addition, the importance of this issue for
orthodontists in terms of determining the treatment plan and time to start orthodontic
treatment in children with ECC, studying this study can be very useful.
materials and methods:
In this study, first 45 children with severe ECC scientific definitions were selected. Then,
for each child who had severe ECC, two more children, one with mild to moderate ECC
and the other with moderate to severe ECC, and at the same time in terms of study
parameters (child gender, time frame of first tooth eruption and child's chronological age
and life Rot) were matched with each other, were selected. Thus, 45 groups were formed,
each with 3 members. As mentioned, in each group, the members are match in terms of
the parameters considered in the study and differ only in the degree and severity of ECC.
Their teeth were determined by Demirjian method and the mean differences of dental age
between different intensities of ECC were calculated.
Results:
In the present study, there was a significant relationship between early childhood caries
and the rate of development of lower permanent tooth buds (or dental age). It was
significantly reduced in children with lower caries severity and at the same time matched
in other factors affecting dental age, and this was true for both girls and boys, indicating
that The slowing down of the permanent lower bud development is due to the increase in
ECC intensity in both sexes.
Conclusion:
With the gradual increase in the severity of ECC and the progression of its clinical stage
in children, dental age is significantly reduced compared to children who have lower
caries severity and at the same time are matched in other factors affecting dental age.
