Abstract

A novel glucanhydrolase from Lipomyces starkeyi KSM 22 has been suggested as a promising anti-plaque agent because it has been shown to have additional amylase activity and mutanase activity besides dextranase activity and to strongly bind to hydroxyapatite. Mouthrinsing with Lipomyces starkeyi KSM 22 glucanhydrolase solution was comparable to 0.12% chlorhexidine mouthwash in inhibition of plaque accumulation and gingival inflammation and local side effects were less frequent and less intense in human experimental gingivitis. In this study, Lipomyces starkeyi KSM 22 glucanhydrolase mouthrinses (1 and 2 unit/ml) were compared with a control mouthrinse (commercial 0.01% benzethonium chloride mouthrinse, Caregargle®, Hanmi Pharmaceuticals) in the ability to inhibit plaque formation.
A 3-replicate clinical trial using 4-day plaque regrowth model was used. Fifteen volunteers were rendered plaque-free on the 1st day of each study period, ceased toothcleansing, and rinsed 2X daily with allocated mouthrinse thereafter. On day 5, plaque accumulation was scored and the washout periods was 9 days for the next trial.
Lipomyces starkeyi KSM 22 glucanhydrolase(1 unit and 2 unit)- containing mouthrinse resulted in significantly lower plaque formation in plaque area and thickness, compared to the control mouthrinse. There was no significant difference in plaque inhibition between enzyme-mouthrinses at 2 different concentrations used. This glucanhydrolase- containing mouthwash resulted in significantly lower plaque area severity index score and tended to have lower plaque thickness severity index score than those of control mouthrinse. But there was no significant difference according to the enzyme concentration.
From these results, Lipomyces starkeyi KSM 22 glucanhydrolase-containing benzethonium chloride mouthrinse has greater anti-plaque effect than the commercial mouthrinse alone. Therefore this glucanhydrolase preparation is a promising agent for new mouthwash formulation in the near future.
