Drake MA, et al. - The efficacy of 3.14% dipotassium oxalate monohydrate-containing strip on the relief of dentinal hypersensitivity (DH) was determined. Furthermore, the authors aimed to ascertain whether there was a difference in DH levels when the strip was self-applied vs applied by a dental professional. They affirmed the short-term (4 weeks) effectiveness of a single application of 3.14% dipotassium oxalate monohydrate-containing strip. In this study, self- and professional application were not found to be different.
