Microbial aspects of preventive regimes in XXXX with overdentures.

The aim of this study was to test effects of preventive regimes using @entity1388 and @entity1216 to prevent @entity2520 in 34 @entity1 with overdentures. The @entity1 , who were treated with immediate overdentures, were distributed at random into three experimental groups. In these groups, different gels--a placebo, a @entity1388 , and a @entity1216 - @entity1388 gel--were tested by daily application. @entity527 samples from selected surfaces of two abutment teeth were taken at one week, and at one, three, and six months after initial insertion of the overdenture. The placebo and @entity1388 gel influenced neither total CFU nor @entity885 and A. viscosus/naeslundii counts. In the placebo group, but not in the @entity1388 group, @entity6586 levels increased significantly, indicating the caries risk involved in overdentures. The use of @entity1216 - @entity1388 gel resulted in a long-term suppression of total CFU. Further, @entity6586 was found to be selectively suppressed to below detection level. A. viscosus/naeslundii was initially strongly suppressed, but after three months a partial return of the population was noticed. @entity885 was relatively insensitive to the @entity1216 - @entity1388 gel. It is concluded that a daily application of a @entity1216 - @entity1388 gel is effective against plaque formation and @entity6586 on abutment teeth in overdentures.
