Assessing the efficacy of three dentifrices in the treatment of dentinal hypersensitivity
Article Abstract:
A toothpaste containing a ratio of 5% potassium nitrate to 0.243% sodium fluoride may be effective in treating hypersensitivity of the dentinal part of the teeth, which lies just under the enamel. Generally, people with teeth that are hypersensitive to touch, temperature, and certain foods use a desensitizing toothpaste with potassium nitrate and an anti-cavity toothpaste with fluoride. For eight weeks, 230 people with dentinal hypersensitivity brushed their teeth with either a toothpaste containing potassium nitrate and sodium fluoride, potassium nitrate alone, strontium chloride, or none of these agents (placebo). Both of the toothpastes with potassium nitrate were more effective than the placebo in reducing general discomfort and sensitivity to cold air and to touch with a probe. Potassium nitrate toothpastes were also more effective than the strontium chloride toothpaste in reducing sensitivity to some stimuli. Side effects such as gum irritation occurred but were not considered serious.

Manual versus powered toothbrushes: the Cochrane review
Article Abstract:
The only powered toothbrushes that are more effective than manual tooth brushing are the rotation oscillation toothbrushes such as the Braun Oral-B from Oral-B Laboratories and the HP 735 from Philips Jordan. This was the conclusion of researchers who reviewed 29 clinical trials covering 2,500 patients. Only the rotation oscillation toothbrushes were more effective than manual tooth brushing in reducing plaque and gingivitis.

The effects of toothpastes on the residual microbial contamination of toothbrushes
Article Abstract:
Most toothpastes do not prevent the bacterial contamination of toothbrushes, even those that contain triclosan. This was the conclusion of researchers who tested toothpastes in 20 patients with periodontal disease. Patients with periodontal disease should change their toothbrushes frequently.
