Introduction: The effectiveness of
caries treatment depends on many factors, such as the condition of
dental tissues, the stage of root development, the period of dentition,
the quality of preparation and isolation, the optimal choice of material
for restoration. The problem of choosing the filling material is acute
in each treatment of caries in children with mixed and permanent
dentition.
The aim: Todetermine and statistically substantiate parameters
for choosing restorative material for permanent teeth in children with
different stages of root development.
Materials and methods: 248 children aged 7 to 11 (122 boys and 126
girls) and 246 children aged 12 to 17 (120 boys and 126 girls),students
of Uzhhorod Secondary School №20 were examined. Restoration materials -
"Polofil Supra" (VOCO, Germany) and "DyracteXtra" (Densply, USA). The
following criteria were investigated: saliva pH, area of destruction of
the occlusal surface of masticatory teeth, stage of root development,
depth of the lesion and cavity topography, the acid resistance of the
enamel. For the purpose of statistical justification of the selected
parameters that pointed as significant in the choice of restorative
materials, and for the analysis of the interrelations of the parameters
studied, the Spearman correlation coefficient (r) was determined. The
correlation coefficient was considered statistically significant when p
<0.05.
Results: For children aged 7-17 years to restore permanent teeth
during the period of mixed and permanent dentition, the best materials
in use were: "Polofil Supra" (VOCO, Germany) and "DyracteXtra" (Dentsply,
USA).
Conclusion: To restore permanent teeth in any stage of root
development, it is rational to use a compomer material "DyracteXtra" (r
= 0.80), and a composite material "Polofil Supra" - under the conditions
of the formed root, at a pH level of more than 6.2, a high degree acid
resistance of the enamel and the area of destruction of the occlusal
surface less than 0.55 (r = 0.72).
