Evaluation of the effectiveness of polishing pastes used in teeth whitening

Abstract

INTRODUCTION. To increase the effectiveness of preventive procedures, it is important to choose the right professional hygiene products. The most common complaint after professional oral hygiene is hypersensitivity of the teeth.
AIM. To study the effectiveness of various polishing pastes.
MATERIALS AND METHODS. The research was conducted on the basis of the Department of Therapeutic Dentistry of the Research Medical University, Nizhny Novgorod, the cytological laboratory, Dental Polyclinic No. 1 (Ryazan). A dental examination was performed on 39 patients of both sexes aged 18 to 45 years with discoloritis of hard tissues, who were exposed to harmful industrial factors and did not have dental hyperesthesia. The control consisted of 13 practically healthy people who do not work in hazardous industries from Ryazan. The patients underwent professional hygiene using 3 types of polishing pastes (based on corundum, perlite, R.O.C.S. PRO POLISHING toothpaste), depending on which the patients were divided into 3 groups of 13 people each.
RESULTS. In all 3 groups, there was a significant difference in the values of IGZ, IRGZ, Schiff and VAS samples from the initial ones (p < 0.05), i. e. hyperesthesia of varying degrees appeared after professional hygiene. The most significant differences between IIGZ, IRGZ, Schiff’s sample and VAS were revealed in groups 1 and 3, the Schiff sample revealed significant differences between groups 1 and 2, differences in the values of IIGZ, IRGZ and VAS were also recorded in groups 1 and 2 of observation. The most pronounced hyperesthesia was observed when using Corundum–based polishing paste, and the minimum was R.O.C.S. paste PRO POLISHING.
CONCLUSION. The existing harmful production factors in workers lead to structural changes in the enamel. When carrying out occupational hygiene for people working in hazardous industries, the most preferable is the use of a paste based on ultrafine silicon dioxide.
