[Microbiological study on subgingival dental plaque in children with chronic catarrhal gingivitis after metronidazole effect].

Clinical and bacteriological studies on sublingual dental plaque have been carried out on 60 juveniles (from 13 to 16 years of age) with chronic catarrhal gingivitis. The therapeutic schedule covers local metronidazol treatment, combined with oral hygiene (OH) and instructions and control for maintenance of OH at home. The results reveal that metronidazol had an excellent antianaerobic action, though the mechanical removal and optimal OH are particularly important for the good clinical results.
