Last year we looked at a number of studies that looked at the effectiveness of various toothpastes in reducing dentine hypersensitivity (Dental Elf 30th October 2012). The aim of this review was to assess the effectiveness of arginine-containing desensitising toothpastes in comparison to control agents in reducing dentine hypersensitivity (DH). The aetiology of DH is usually reported as multifactorial and while this review focuses on the use of arginine containing pastes it also provides a useful table of the various desensitizing agent together with the mechanism of action.
The reviewers searched the Medline, Cochrane Central, Embase and Lilacs databases for randomised and controlled clinical trials. The primary outcome considered was change in pain/sensitivity reported by tactile and air-blast stimuli. Study selection, data extraction, quality assessment and risk of bias assessment was conducted independently in duplicate.
- Only two studies involving 243 patients in total were included.
- Both studies were conducted by the same team.
- One study was of 3 days duration the other of 8 weeks.
- Both studies reported greater improvement in DH with the arginine paste.
The authors concluded
Data identified indicates a potential role for arginine-containing toothpastes in managing dentine hypersensitivity. However, this conclusion is based on small sample sizes and the studies identified did not follow patients up in the medium to long term. The authors recommend that there is a need for well-designed RCTs to be conducted prior to any definitive recommendations being made.
