Laboratory evaluations of three dentifrices with polishing or brushing.
The purpose of this study was to determine the depth of deposit removal of three dentifrices using a dental felt polishing tip or an Oral-B P 35 toothbrush. The dentifrices were compared using a laboratory method which simulates clinical tooth polishing or toothbrushing procedures, and utilizes a pressure-sensitive paper that records the depth of deposit removal. Each polishing time was conducted for five seconds; toothbrushing time was 15 seconds. Both polishing and toothbrushing were performed at a weight of 250 grams. Depth of Deposit Removal (DDR) was recorded using a 0-4 scale from a comparative color chart. The dentifrices evaluated were Arm & Hammer Dental Care, Colgate Regular, and Crest Regular. Twenty-four replicates of each dentifrice, tested undiluted, were performed. Results indicated that dentifrice efficacy was ranked numerically as Arm & Hammer Dental Care > Colgate Regular > Crest Regular. In all of the assays the Arm & Hammer Dental Care dentifrice had significantly (p < 0.01-0.001) higher DDR mean values compared to the Colgate Regular and Crest Regular dentifrices. The Colgate Regular dentifrice was significantly (p < 0.01-0.001) superior to the Crest Regular dentifrice in the assays conducted.
