Personified Orthodontic Treatment of Adults with Malocclusions and Deformations in Dentition Depending on the Degree of Caries Resistance of the Dental Enamel

Background: To increase the effectiveness of orthodontic treatment in children with various degrees of dental enamel caries resistance using a personified orthodontic treatment. Materials and Methods: The present study included 108 adults (6-16 years old) with the first class of occlusion who referred for the Department of Pediatric Dentistry with orthodontics in Voronezh pediatrics’ dental clinic №2" Russian Federation. According to the study design, it can be characterized as open, prospective, and clinical. The electrometric diagnostics of dental enamel and electromyography of the masseter and temporalis were recorded. Results: Functional therapy with the proposed personified orthodontic treatment normalized the mean number of biopotential masseters and temporalis muscles and improved caries resistance of hard dental tissues. However, the examination on the group of children with a low degree caries resistance of dental enamel resulted in the decrease in the mean number of electrometric diagnostics from 4.0 (3.6; 6.0) μA-1.6 (1.5; 3.37) μA (differences are statistically significant, p˂0.05) after 18 months of replacement therapy. In turn, the mean number of bioelectric activity of masseter and temporalis muscles changed from 324.25 (303.75; 345.75) μV-332.5 (318.75; 347.25) μV, p˂0.05. Conclusion: Employing the personified orthodontic treatment depending on the degree of caries resistance of the tooth enamel, determination of the functional state of the masseter and temporalis, and electrometric diagnosis of dental hard tissues enhanced the effectiveness of orthodontic treatment.
