Conditions

Adult Periodontitis

Brief summary

Periodontal disease (commonly called gum disease) is generally treated by deep cleaning of the root surfaces of the teeth. This is also called scaling and root planing. Placing a topical antibiotic into the periodontal pocket at the time of scaling and root planing may help reduce pocket depth and thus help the periodontal disease. Periocline (minocycline HCl) 2.1% gel is a topical antibiotic approved in a number of countries for this use, and is now being tested in the US.

Interventions

DRUGminocycline HCl 2.1%

Minocycline HCl 2.1% gel as an adjunct to scaling and root planing. Dosing is by topical delivery into gingival pockets at baseline, 2 weeks, 4 weeks, 3 months and 6 months.
