Efficacy evaluation of rubber cup and air polishing techniques using glycine in plaque and stain removal - A clinical trial

Abstract

Background: Researchers have proved Glycine to be safe, less abrasive, sweet and comfortable for patients. It is beneficial in removing plaque as well as stains. The present study aims to compare the plaque and extrinsic stain removal efficacy of the air-polishing device and rubber cup prophylaxis technique along with a comparative evaluation of the gingival trauma caused by both the techniques. Method: This split-mouth randomized clinical trial was conducted on a total of 60 subjects in half of whom, left side was assigned to Glycine powder air polishing and the right side to rubber cup prophylaxis with (Glycine powder) and vice versa in the other half. All the subjects had their calculus removed one month prior to the intervention. Plaque index, Stain index and Trauma index were recorded and statistical analysis was done. Results: Both the techniques (RCP and AP) demonstrated a significant reduction in plaque and stains within their respective groups, but revealed non-significant differences between the study groups. Gingival trauma was found to be significantly higher in case of AP group. Rubber cup technique was preferred over air polishing by the subjects. Conclusion The data indicates that both the techniques were equally beneficial for plaque and stain removal, but rubber cup polishing technique has an advantage over the air polishing technique.

Evaluation of the Efficacy of Low-Particle-Size Toothpastes against Extrinsic Pigmentations: A Randomized Controlled Clinical Trial

“…Extrinsic pigmentations are related to the bacterial biofilm [ 11 ] and can be removed during professional oral hygiene sessions with mechanical debridement, polishing (using pastes with variable relative dentin abrasivity index—RDA) and air-polishing system techniques (using powders of different abrasiveness, such as glycine, bicarbonate, or calcium carbonate), in order to disrupt the bacterial biofilm and remove the stains [ 12 ].…”

“…In vitro and in vivo studies evaluating the effects of toothpaste have been reported in the literature, using different ingredients, such as surfactants, peroxide, enzymes, citrate, pyrophosphates and hexametaphosphate [ 10 , 12 ]. The primary stain removal ingredient tested in whitening toothpaste is the abrasive molecule.…”
