PREVENTION OF DENTAL CARIES IN CHILDREN WITH DIFFERENT LEVELS OF ENAMEL RESISTANCE

Abstract

Purpose of the study. To evaluate the effectiveness of prevention of dental caries in children with different levels of enamel resistance. Research methods. There were 154 children aged 6–7 years under observation, from them 78 children of the main group (25 children with caries-resistant enamel, 27 – with conditionally resistant and 26 – with cariesresistant enamel) and 76 children of the comparison group (25 children – with caries-resistant enamel, 25 – with conditionally resistant and 26 – with caries-resistant). The set of caries-preventive measures, received by the children of the main group included: hygienic education of children and their parents; professional oral hygiene with covering of teeth enamel with fluoride varnish; quality control of oral hygiene state using Mira-2-Tone liquid or tablets to visualize plaque at home and during a visit to the dentist; differentiated use of exogenous prophylaxis. The children of the comparison group underwent professional oral hygiene twice a year, hygienic training and education, and were recommended to use fluoride-containing toothpastes. Research results. Carrying out preventive measures for 12 months contributed to a significant reduction in TER values in children of the main group with enamel resistant to caries by 17.26%, with conditionally resistant – by 6.41% and caries-resistant enamel – by 38.46%. After 24 months, children with caries-resistant enamel TER decreased by 28.63%, with conditionally resistant – by 26.75%. The largest increase in enamel resistance was achieved in children with caries-susceptible enamel (by 61.70%). The mineralizing potential of oral fluid in children of the main group after 12 months of follow-up increased by 6.82%, and after 24 months – by 11.80%. The most pronounced changes in the MPRR of oral fluid under the influence of preventive measures were found in persons with caries-susceptible enamel. Thus, for 12 months the observation of children of the Ministry of Regional Development and Public Works increases by 38.99%, and for 24 months – by 45.13%. Instead, in children of the comparison group, the value of this indicator does not change. Conclusion. The results of the study both after 12 months and after 24 months confirmed the effectiveness of the proposed preventive measures by increasing the level of enamel resistance: reducing the TER in children with caries-sensitive enamel from 6.84±0.21 points to 4.23±0.19 points, increasing MPRD and reduction of the increase in caries intensity by 57.89% for the period of 12 months and 62.80% for the period of 24 months of observation, improvement of the hygienic condition of the oral cavity.
