The Effect of Different Interdental Cleaning Devices on Gingival Bleeding

Objective: To compare the effectiveness of an oral irrigator (OI) with a prototype jet tip or a standard jet tip to floss as adjunct to daily toothbrushing on gingival bleeding. Methods: In this single masked, 3-group parallel, 4-week home use experiment, 108 subjects were randomly assigned to one of three groups: 1) OI with a prototype jet tip; 2) OI with a standard jet tip; 3) waxed dental floss. All groups used their assigned product once a day as adjunct to twice daily toothbrushing for...

Additive or Synergistic Antimicrobial Effects of Amoxicillin and Metronidazole on Whole Plaque Samples: A Preliminary Report
Additive or Synergistic Antimicrobial Effects of Amoxicillin and Metronidazole on Whole Plaque Samples: A Preliminary Report

Objective: In vitro data on the susceptibility of oral bacteria to the combination of metronidazole and amoxicillin is limited. The aim of this preliminary study was to determine the susceptibility of whole subgingival plaque samples to amoxicillin and metronidazole and to their combination. Methods: Prior to any treatment procedures subgingival plaque samples from patients with severe generalized periodontitis were taken. Appropriate dilutions were plated on Columbia blood agar supplemented...

Clinical and Microbiological Comparison of Three Non-surgical Protocols for the Initial Treatment of Chronic Periodontitis

Objective: To compare the clinical and microbiological effects of three protocols for nonsurgical periodontal therapy, including full-mouth scaling and root planing plus systemic antibiotics, on the treatment of chronic periodontitis patients. Methods: Twenty-nine patients diagnosed with moderate to severe chronic periodontitis, selected according to specific criteria, were randomly assigned to one of three treatment groups: quadrant scaling, full-mouth scaling, and full-mouth scaling...
