Features of the Process of Maturation of Enamel Cusps and Fissures of Premolars After Their Eruption in Children

Objectives: The study of the timing and features of the maturation process of tooth enamel in
children is important for the prevention of dental caries in children. Teeth erupt
with low salinity. The possibility of further regulation of maturation of tooth
enamel in the mouth to a state of stable full maturity is the basis for the planning of
preventive measures.

The aim of this study was to determine characteristics of process of maturation of
enamel cusps and fissures of premolars after their eruption in children with
controlled and uncontrolled hygiene.
Methods: Materials and methods. Clinical group of 50 children 9 – 12 years old (25 of
uncontrollable hygiene, 25 of controlled hygiene) was studied during two years.
Time of enamel maturation of first upper permanent premolars since their eruption
was studied in dynamics by electrometry. Fissures were investigated since the
possibility of electrometry as tooth eruption observed. Electrometer was carried out
in terms of: 3 days, 1 week, 2 weeks, 1 month, 3 months, 6 months, 1 year, 1.5
years and 2 years.
Results: Results of the study showed that maturation of the buccal and lingual cusps occurs
equally and completed the first year after the eruption. The most active maturation
process occurs between 3 months and 1 year after the eruption. Differences in the
process of maturation of the buccal and lingual cusps of permanent premolars were
not identified.
Conclusions: Conclusion. The process of maturation in the cusps and fissures varies. Baseline
mineralization in the cusps is 2 times higher than in the fissures, the growth is
gradual mineralization and ends at 1 year. Mineralization of fissure significantly
lower after 1 year indicated demineralization process that dictates the need for
active prevention during this period.
