8.1 Introduction—current challenges in preventive dentistry
Dental prophylaxis based on mechanical biofilm management and fluoride application has resulted
in considerable improvement of oral health; however, caries is still a great challenge worldwide.
The caries prevalence in newly industrializing countries is still increasing, in industrialized
countries it is stagnating or decreases in some sections of the population [1,2] . Noteworthy, the dis-
tribution of caries in the population has shifted. On the one hand, many seniors of today have their
own teeth but are faced with caries especially at the neck region of the teeth due to exposed dentin
surfaces [3] . On the other hand, many children are nearly free of caries, but a significant percentage
is faced with extensive early childhood caries [2,4] . If thorough mechanical biofilm management
is performed daily on every site of the teeth, there will be no new caries lesion formation or
