Aim to assess the sensitivity of hard dental tissues after home teeth whitening with various kits. Material and methods. The study involved 45 people aged from 20 to 35 years with enamel color A3 and darker on the Vita Classical scale arranged in chromatic order. Using the random sampling method, all patients were divided into 3 groups, 15 people in each group. The course of home whitening lasted for 14 days with the following administration of a course of remineralization therapy for 2 weeks. The presence of hypersensitivity was evaluated before the course of home teeth whitening, after 3 days, 7 days, 2 weeks and 1 month. Results. The study revealed the highest incidence of hyperesthesia during home teeth whitening in patients of the first group, who used a hydrogen peroxide content of 10%. Presumably, the high percentage of the occurrence of dental hyperesthesia of 2nd degree in patients of this group resulted from the use of hydrogen peroxide as a whitening component, which is a more aggressive agent, if compared to carbamide peroxide. Conclusion. Home teeth whitening using a system containing 22% carbamide peroxide eliminates the risk of tooth hyperesthesia, since the whitening gel is used in individual trays, carbamide peroxide is used as a whitening agent, and the introduction of amorphous calcium phosphate into the gel does not cause fluid movement in dentinal tubules, thereby not causing sensitivity of the hard tissues of the teeth.

Subject. Mineralization of hard dental tissues and its correction in patients after radiation therapy for malignant neoplasms. Objectives. To develop a method for remineralization of hard dental tissues in patients after radiation therapy for neoplasms of the maxillofacial area using Raman fluorescence spectroscopy. Methodology. The study was conducted on a group of people who had previously received radiation therapy for malignant neoplasms of the head and neck, matched by gender and age, who voluntarily agreed to take part in it. The main group consisted of 20 people who underwent the proposed remineralization complex. Comparison group – without using the proposed complex. A study of Raman fluorescence of teeth was carried out using the InSpectrum computer in three areas (neck, equator, incisal edge) in patients before and after correction. Results. Raman fluorescence diagnostics of the tooth surface made it possible to clearly see the difference in mineralization in digitized indicators. The data for patients in the main group after correction of mineralization (y = 304, x = 963 cm-1) are higher than for patients in the comparison group (y = 287, x = 963 cm-1). Conclusion. In different areas of the tooth surface, the level of mineralization of hard tissues differs: neck (216 ± 0.019, x = 963 cm-1), equator (389 ± 0.024, x = 963 cm-1), cutting edge (282 ± 0.016, x = 963 cm-1). The Raman fluorescence diagnostic method allows you to monitor changes in mineralization. The developed method of remineralization of hard dental tissues in patients after radiation therapy for neoplasms of the maxillofacial area using Raman fluorescence spectroscopy makes it possible to influence mineralization and is recommended for further research to prevent the development of radiation caries

Subject. Changes in the mineralization of hard tissues of teeth under the influence of radiation factor. Objectives. To study the effect of radiation factor on the level of mineralization of hard dental tissues by Raman fluorescence. Methodology. The study was conducted at the Department of Orthopedic Dentistry and Orthodontics of the SUSMU. The study was conducted on clinically removed teeth. All teeth were divided into three groups depending on the amount of radiation exposure (2 Gy, 70 Gy, 110 Gy). The main research method was the study of raman fluorescence of tooth sections on the hardware and software complex "InSpectr" with diagnostic sensitivity for the integral concentration of aerobic-anaerobic microbial suspension up to 109 CFU/ml. Teeth were examined in three areas (neck, equator, cutting edge) before and after radiation exposure. Results. Raman fluorescence diagnostics of the tooth surface made it possible to visually see the difference in mineralization in digitized indicators. For example, according to the indicators before and after exposure to the radiation factor, it is clear that the mineralization indicators, regardless of the dose, had no significant differences. At the same time, there are significant differences in the level of mineralization in the area of different tooth settings (equator, cervical region, cutting edge). Conclusion. In different areas of the tooth surface, the level of mineralization of hard tissues differs. The smallest is observed in the area of the neck of the teeth (incisors, y = 145 ± 1.5, x = 963 cm-1, canines, y = 141 ± 1.1, x = 963 cm-1, premolars, y = 142 ± 1.8 , x = 963 cm-1, molars, y = 143 ± 1.3, x = 963 cm-1), middle, in the area of the cutting edge and occlusal surface (incisors, y = 374 ± 1.7, x = 963 cm-1, canines, y = 377 ± 1.3, x = 963 cm-1, premolars, y = 375 ± 1.2, x = 963 cm-1, molars, y = 375 ± 1.1, x = 963 cm-1), and maximum, in the equator region (incisors, y = 413 ± 1.1, x = 963 cm-1, canines, y = 414 ± 1.9, x = 963 cm-1, premolars, y = 415 ± 1.7, x = 963 cm-1, molars, y = 419 ± 1.6, x = 963 cm-1). The method of Raman-fluorescence diagnostics makes it possible to detect changes in mineralization due to the potential difference in the areas of hard tooth tissues in various areas (neck, equator, cutting edge) of all functional groups of teeth (incisors, canines, premolars, molars) both before and after direct radiation exposure, direct radiation exposure does not significantly change the level of mineralization of hard dental tissues, regardless of the dose applied in all functional groups (incisors, canines, premolars, molars), in all areas of the teeth (equator, cutting edge, cervical region).
