A pilot study on the degree of tooth staining caused by pollen water and Chlorhexidine: in vitro study

Background: Chlorhexidine oral rinse has been used as an adjuvant in the treatment of periodontal disease. However, there are draw backs of using chlorhexidine i.e. tooth staining and other side effects including allergy reaction. In light of proven therapeutic properties of pollen water as well as its relatively cheap cost in the market, pollen water has a potential to be an effective alternative to chlorhexidine oral rinse. The aim of this study is to compare the degree of tooth staining influenced by pollen water-based mouthwash to the standard Chlorhexidine mouthwash using spectrophotometer.

Materials and Methods: 24 Specimens from extracted intact human teeth were soaked into the three different solutions, Pollen water, and normal water. Color measurements were carried out by a spectrophotometer devise and recorded at 5 different time intervals. Color change (ΔE), Chroma (C*) and Hue (H*) were analyzed and compared among the three solutions.

Results: Overall mean ΔE was simi...
