ANALYSIS OF THE CLINICAL EFFICIENCY OF RESTORATIVE FILLING MATERIALS

Aim. To conduct a clinical assessment of short- and long-term surface sealing in patients having a different hygienic status of the oral cavity.

Materials and methods. For clinical trials, a group of 250 male and female patients aged 25–45 years old and diagnosed with Black’s class III and V carious lesions was selected. All patients were divided into three groups depending on the state of oral hygiene and the applied methods of aesthetic restoration: control group — defect restoration by Filtek Z-250 microhybrid composite (3M ESPE); comparison group — Filtek Z-250 restoration (3M ESPE) + Easy Glaze (Voco) surface sealing on the day of restoration; and the main group with three subgroups: 2α subgroup — Restavrin restoration + Easy Glaze sealant on the day of treatment; 2β subgroup — Restavrin restoration + Easy Glaze sealant on the day of treatment and re-sealing with a frequency of 1 time per year; 2γ subgroup — Restavrin restoration + Easy Glaze sealant on the day of treatment and re-sealing with a frequency of 1 time per 6 months. The quality of caries cavities was assessed by USPHS criteria, including anatomical shape (AS), marginal pigmentation (MP), marginal adaptation (MA), the presence of secondary caries (SC) and sensitivity (S). The evaluation was conducted on the day of the visit and following 6, 12 and 24 months.

Results. A comparison of the clinical evaluation of photocomposite restorations by the Filtek Z-250 (3M ESPE) microhybrid composite in the control group of patients, in comparison group and in the main Restavrin (Technodent) group showed that the Easy Glaze (Voco) surface sealing of the Restavrin composite restorations carried out in the 2α subgroup of the main group onе time on the day of restoration, in the 2β subgroup with re-sealing after 12 months, and in the 2γ subgroup with sealing every 6 months had allowed the maximum number of restorations to be corresponded to the “satisfactory” value according to the AS, MP, MA, SC, S evaluation criteria throughout the entire observation period.

Conclusion. The Restavrin (Technodent, Russia) polymeric nanohybrid fi lling material is shown to produce the most effective and durable restorations compared to other materials under study. The applicatiyon of Restavrin followed by the Easy Glaze (Voco) sealing protective system with a frequency dependent on the hygienic status of the oral cavity allows therapeutic methods for dentin caries treatment to be optimized.
