Background: Biofilm removal is the central part of the etiotropic and maintenance phase of periodontal therapy. Commercially available injection water jets such as Prophy-Jet allows an efficient and convenient biofilm removal as an adjunct to mechanical periodontal therapy. But, due to the abrasive nature of traditionally used air polishing powders such as sodium bicarbonate, there is a continuous research going on for less abrasive materials. Aims: To compare the effectiveness of air polishing using glycine powder and chlorhexidine acetate powder on tooth surface as compared to ultrasonic scaling and also to evaluate the time taken for stain removal. Materials and Methods: Thirty fully erupted, single rooted teeth extracted due to poor periodontal prognosis were used in this in-vitro study. The sample teeth were divided into 3 equal groups and stained in coffee solution. The test Groups A and B underwent air-polishing with glycine powder and chlorhexidine acetate powder respectively. Group C was control group and underwent ultrasonic scaling. Time taken for stain removal was recorded. The sample teeth were also evaluated under a stereo-microscope and digital micrometer preprocedurally and post-procedurally to measure surface changes. Results: The study showed statistically significant results (p<0.05) when measurements of changes in surface roughness of samples treated with glycine powder air-polishing were compared with ultrasonic scaling and chlorhexidine acetate powder air-polishing were compared with ultrasonic scaling. Surface texture loss as well as time taken for stain removal was minimum with glycine powder and maximum with ultrasonic scaling. Conclusion: Air-polishing with glycine powder was least abrasive on root surface followed by chlorhexidine acetate powder air-polishing. This is because of the lower particle size of glycine which also covers larger area in lesser time.

Abstract Introduction The staining of artificial teeth can be related to the acrylic resin abrasion caused by brushing, resulting in higher deposition of dyes from the beverage, and consequently higher aesthetic damage. Objective The aim of this in vitro study was to evaluate methods for removal of stains from acrylic denture teeth using spectrophotometric analysis. Material and method Artificial teeth were divided into twelve groups (n=10) according to the type of treatment (re-polishing - Re or immersion in Corega Tabs - Sp), staining solutions, coffee (Cf) and Coca-Cola® (Cc) or water (W) and with/without toothbrushing (B). The Sp specimens were submitted to seven immersion cycles (5 min each). The Re specimens were polished with pumice stone followed by Spain white paste. Color differences (ΔE) were captured by a spectrophotometer: T0 (baseline), T1 (after brushing/immersion in solutions) and T2 (after Re or Sp). Result Statistically significant color change between T1 and T2 (paired T-test; α =.05) was observed for the group CfSp (p=.032); and for the groups BWRe (p=.000), BCfRe (p=.049) and CcRe (p=.042). Higher color changes were observed for the specimens submitted to toothbrushing (ANOVA two way; p<.001). Conclusion It could be concluded that the immersion in sodium perborate (Corega Tabs) can be used for removal of coffee stains from denture teeth, and re-polishing for removal of Coca-Cola® stains. Still, toothbrushing produced greater color changes on denture teeth, regardless of the immersion solution.
