While the term "polishing" has been employed to refer to the expert elimination of soft deposits and stains from the surfaces of teeth, this encompasses both cleaning and polishing.
To compare invitro the surface roughness and stain Remover Ability of Prophylaxis Paste and Biochar gel for Stained Teeth Based on Cucurbita Moschata.
Materials and methods: study was carried out on 10 sound non-carious periodontally involved human premolars teeth after getting the patients’ approval (age of 20-40 years). Teeth were then immersed in black tea for 24 hrs. After staining, all specimens were stored in artificial saliva for 7 days. Then randomization by software divided in to 2 groups: Group 1: Prophylaxis paste, Group 2: Biochar Gel. Specimens were embedded in self-cure acrylic resin and allowed to set to create blocks. Specimen was divided horizontally into three thirds by permanent colour marks. Each sample were subected to Mitutoyo Surface Roughness Tester pre and post polishing in both groups. Shade Assessment of the three thirds of each sample were assessed before and after polishing per group by VITA Easyshade® V.
Results: In surface roughness, Comparison between prophylaxis paste and Biochar Gel revealed insignificant difference as P was 0.46 and 0.27 regarding pre-and post-polishing respectively. Regarding stain remover ability, comparison between Biochar gel and prophylaxis paste groups regarding post-polishing VITA SYSTEM 3D- MASTER shade guide and VITA classical shade guide showed no significant difference as P>0.05.
Conclusion: Biochar Gel Based on Cucurbita Moschata is considered a promising alternative to prophylactic pastes
