Dentifrices--an update.

OBJECTIVES

The objective of this paper was to review the published evidence concerning the efficacy and potential for adverse reactions of modern dentifrices toothpastes.

DATA SOURCES

Publications cited on MEDLINE since 1990. Some further pre-1990 publications are also referenced.

DATA SELECTION

Studies concerning the efficacy of dentifrices and their components and any related putative adverse incidents.

DATA EXTRACTION

Papers were scrutinised for scientific and trial data.

DATA SYNTHESIS

Data concerning the efficacy of dentifrice components were summarised.

CONCLUSIONS

The efficacy of fluoride salts in dentifrices in reducing dental caries is well established. Toothpastes, containing triclosan, are effective in improving plaque control, gingivitis and periodontal health. Other toothpaste formulations are effective in reducing the formation of calculus, extrinsic tooth stain, dentine sensitivity and oral malodour. The consumer now has available a range of toothpastes which deliver oral health benefits. Adverse reactions to toothpastes are rare but should be considered in unexplained skin or respiratory allergies and gingival or lip lesions.
