Study Notes
Chemical Plaque Control
- Adjunctive aids for subgingival plaque include subgingival irrigation, controlled-release devices, and systemic antibiotics.
Subgingival Irrigation
- Delivers solutions deep into periodontal pockets via mechanized handpieces, irrigators, ultrasonic devices, and syringes.
- Techniques using needles and cannulas for irrigation are effective.
- Chlorhexidine, stannous fluoride, and phenols, as well as antibiotics, are used in irrigation solutions.
- Tetracycline is absorbed by root surfaces, with therapeutic levels maintained for up to a week after irrigation with a 100mg/ml solution for 5 minutes.
- Weak performances of chemotherapeutic agents are due to inability to maintain adequate concentration and rapid clearance by crevicular fluids.
Controlled-Release Devices
- Site-specific, controlled-release delivery systems allow administration of drugs to infection sites for extended periods.
- Active ingredients are incorporated into fibers, gels, chips, collagen film, acrylic strips, and polymers, which then release the drug over days.
- Sufficient reservoir size is necessary to offset flushing action of crevicular fluid.
Systemic Antibiotics
-
Antibiotics reach widely distributed microorganisms in the body.
-
Only a small portion of the total dose reaches subgingival microflora.
-
Systemic antibiotics pose a higher risk of side effects compared to local delivery.
-
Metronidazole is used for severe cases of ANUG.
-
Various commercial preparations of antibiotics are available, e.g., Actisite, PerioChip, Atridox, Arestin, Dentomycin, and Elyzol.
