This research poster addresses the question “What differences exist between erythritol, glycine, and sodium bicarbonate powders in air polishing?” The use of air polishers in the dental field is highly recommended; however, the ability to determine the correct powder and grit for each patient can be vital. The three types of powders have different pros and cons related to their function; though most studies show significant advantages of using air polishing in general. One study compared erythritol powder and the ultrasonic. In the results, pocket depths were decreased but there was no difference in effectiveness between the two; however, a decreased pain perception was observed in the air polisher. Another study compared the effects of erythritol, glycine (GPAP) and the ultrasonic, finding a significant difference between the air polishers and the ultrasonic in lowering bacteria count. Results of many of these studies favored erythritol and glycine powders over sodium bicarbonate (SBAP) due to the increased coarseness of sodium. The selectivity of these types of powders can increase individualized patient care. In conclusion, the usage of air polishing in dentistry, regardless of type of powder, shows remarkable improvements in oral health.
