Determination of nicotine content in teeth submitted to prophylaxis and in-office bleaching by gas chromatography –mass spectrometry (GC-MS)

ConclusionsCigarette smoke penetrates into the dental structure. Dental prophylaxis and bleaching with 35% hydrogen peroxide can partially remove the nicotine from tobacco smoke. However, when in-office bleaching was applied, a more significant nicotine removal was achieved.Clinical significanceDental prophylaxis could remove most of the external nicotine-staining on the tooth surfaces while bleaching could further reduce the external and internal nicotine-staining of teeth.
