Abstract

Aim To evaluate the potential of two whitening toothpastes on stain removal, using two different spectrophotometeric devices. Design In a randomised, double-blind clinical trial, 150 participants with tooth discolouration were assigned to use one of three toothpastes containing: hydroxyapatite, calcium peroxide and no active ingredient (placebo). They were examined at baseline and after 4, 8 and 12 weeks. Measures Two methods of colour measurement were used: Vita Easyshade (Vita 3D-master scale) and Degudent Shadepilot (Classical Vitashade scale). Results No significant improvement was observed after using the two spectrophotometeric methods. However, a subjective lighter tooth colour and less staining were perceived by the participants in all three groups (not significant). Moreover, there was a significant improvement in the gingival and plaque index in all three groups after the 12 weeks. Conclusions The toothpaste containing hydroxyapatite or calcium peroxide did not produce any reduction in tooth staining compared with a placebo fluoride toothpaste.

  • The systematic search for in vivo evidence resulted in six studies ranging in quality from very low to moderate.

    “The results of the systematic search for in vivo evidence resulted in six studies [42,49,50,51,52,53] ranging in quality from very low to moderate (Table 3).”

  • Two in vivo studies were claimed to be double blinded, randomized clinical trials, but details were not provided.

  • For Raoufi and Birkhed 2010, the GRADE assignment is LOW because only a very small amount of HAP was used (0.1% HAP or less; no exact amount was given), while other studies tested concentrations up to 20-30% HAP.

    “LOW-only a very small amount of HAP was used (0.1% HAP or less; no exact amount was given); other studies tested concentrations up to 20–30% HAP; -interestingly, even the peroxide group was not superior to a control toothpaste.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
