Comparative evaluation of changes in the ultrastructure of tooth enamel and dental implants using air-abrasive methods of surface decontamination in the process of carrying out professional oral hygiene
Relevance. To remove above-gum deposits and under-gum deposits air-abrasive methods are widely used. However, the mechanical properties of air-abrasive products are not known to ensure professional hygiene in the feld of exposure various tooth structures. In this regard more detailed studies on these issues are therefore needed. The aim of the present study was to undertake an comparative analysis of changes in the ultrastructure of the surface of tooth hard tissues when they are processed by powders consisting of sodium bicarbonate, calcium carbonate, glycine and trehalose.Materials and methods. The production of vertical teeth grinding, thickness 1-2 mm, removed by orthopedic or orthodontic indications; the processing of these sections by air-abrasive powders in compliance with the Protocol of use of these funds from the manufacturers during the professional hygiene and the study of the samples by scanning electron microscopy (SEM) by a special technique.Results. The answer to the task was the data of comparative analysis of damage to the enamel surface as a result of processing by various air-abrasive systems and the determination of the least traumatic method of conducting professional oral hygiene in relation to the enamel surface.Conclusions. Processing of enamel by air-abrasive method using powder based on trehalose, glycine and calcium carbonate, observing the recommended conditions for the use of these systems, does not lead to a signifcant change in the enamel ultrastructure, damage or deformation, unlike powders based on calcium bicarbonate. Therefore these systems can be recommended during maintenance periodontal therapy for the prevention of periodontal diseases and dental caries for a long period of time. However, the use of powder based on calcium carbonate is not desirable in the area of dental implants and orthodontic structures such as braces, since the powder remains on these surfaces unchanged and can subsequently cause an exacerbation of inflammatory processes in soft tissues.
