The present invention relates to new chemical compounds which can be used as inhibitors of dental plaque, and orally-acceptable compositions thereof, combinations thereof with known compounds having an inhibitory action on the formation of dental plaque, such as biguanidines, and method of treating therewith for the prevention of dental plaque or tartar and dental caries. The new compounds have the general formula ##STR1## in which R.sub.1 = H or alkyl R.sub.2 = ch.sub.2 oh, alkyl carboxylate, ##STR2## and R.sub.2 is in 2 or 3 position. Compositions containing these active principles are useful in particular in the preventive treatment of periodontopathies and odontopathies and in the field of oral-dental hygiene.
本发明涉及新的化合物,可用作口腔菌斑的
抑制剂及其口服可接受的组合物,与已知的具有抑制口腔菌斑形成作用的化合物(如双胍类)的组合物,以及使用它们进行预防牙菌斑或牙石和龋齿的方法。新化合物具有一般式##STR1##其中R.sub.1= H或烷基R.sub.2= ch.sub.2 oh,烷基
羧酸酯,##STR2##且R.sub.2在2或3位置。含有这些活性成分的组合物在预防牙周病和口腔病方面特别有用,以及在口腔-牙齿卫生领域。
