A comparative assessment of the occurrence of hyperesthesia after a course of home teeth whitening with various kits

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.
