Definitions

  • the present invention relates to an oral care composition comprising an invertase, use of said composition as medicaments, use of said composition in treatment of oral disease, methods of treatment comprising administering said composition to a human subject, methods of preventing or removing oral biofilm comprising contacting an oral biofilm with said composition, methods for reducing the risk of oral biofilm formation, and kits of parts comprising said composition.
  • Biofilms are communities of bacteria that are found on solid surfaces in many different environments, including surfaces of the oral cavity.
  • Oral biofilm, or dental plaque contains many of the bacteria that are associated with oral health issues such as oral malodor, demineralization, dental caries, tooth decay, potential loss of teeth and gum disease (gingivitis and periodontitis).
  • the formation of oral biofilm occurs in three stages known as the lag phase, growth phase, and steady state, respectively.
  • the lag phase glycoproteins from saliva bind to an oral surface such as teeth and create a structure termed the pellicle that functions as attachment site for bacteria.
  • the growth phase co-aggregation occurs, i.e., secondary bacterial colonizers attach to the primary bacterial colonizers, causing the diversity of the biofilm to increase and the biofilm to grow and mature.
  • the biofilm growth slows down and eventually stops. This stage-based formation cycle causes biofilms to exist in several consecutive layers, which makes physical abrasion of biofilm more difficult.
  • the residing bacterial cells are distributed in an extracellular polymeric matrix that consists primarily of water, proteins, exopolysaccharides, lipopolysaccharides, lipids, surfactants, and extracellular DNA, with exopolysaccharides occupying a major fraction of the dry weight of biofilm (H. C. Flemming, and J. Wingender (2010), Nat. Rev. Microbiol. 8, 623-633).
  • the exopolysaccharides are mainly glucose and fructose homopolymers, including (1-3)-a-D-glu- cans, (1-4)-a-D-glucans, (1-6)-a-D-glucans and (2-6)-p-D-fructans.
  • Mutans and dextrans are particularly important glucans in the formation of dental plaque. Mutans have a highly branched structure with main chains composed of glucose molecules linked with (1-3)-a bonds and (1-6)-a-glycosidic linkages in their side chains. Dextrans are also high molecular weight polymers of glucose containing numerous consecutive (1-6)-a-linkages in their backbone and side chains, which begin from the (1-3)-a-linkage (M.
  • Fructans are primarily linear polysaccharides and consist mainly of p-(2,6)-linked fructosyl residues and some
  • biofilm removal has been on mechanical abrasion.
  • mechanical removal of biofilm e.g., by brushing the teeth, expands and deepens the areas in the oral cavity where biofilms attach and expand, thus potentially increasing the severity of the problem rather than reducing it.
  • WO 1997/38669 describes oral care compositions comprising a mutanase and a dextranase
  • WO 1998/57653 provides oral care compositions comprising a dextranase and a pullulanase

  • Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241 : 53-57; Bowie and Sauer, 1989, Proc.

Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using standard methods in the art. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide.
