Comparative evaluation of clinical efficiency of different generations of air-polishing powders during professional oral hygiene

Relevance. Currently, a preventive system based on organic matter - carbohydrate trehalose has appeared on the dental market. The relevance of the research topic is determined by the need to study its properties and conduct a comparative assessment of different generations of air-polishing powders . The purpose of the study is to conduct a comparative assessment of the clinical efficiency of different generations of air-polishing powders during the professional oral hygiene.

Materials and methods. The study involved 38 patients who underwent professional oral hygiene using prophylactic systems of various generations. The oral cavity was preliminarily divided into two sides, depending on the airabrasive agent - based on calcium carbonate (65-70 µm) and trehalose (65 µm). During professional oral hygiene, the time required to remove soft dental deposits was evaluated, and after the procedure, the state of the oral cavity was measured using dental indices. In addition, a questionnaire was used for patients and dentists.

Results. The average time for the removal of the soft dental deposits using an air-abrasive agent based on calcium carbonate was 4.5 ± 3.6 min and 4.4 ± 3.8 min based on trehalose. The difference in the average time between the two groups was insignificant (P = 0.461); there was also no significant difference in the average values of the dental indices. The opinion of the dentists and patients about the two preventive systems was comparable.

Conclusions. Trehalose-based air-abrasive product is effective, safe, ergonomic and can be recommended for the use of dentists and dental hygienists.
