- 12. Fluoride in periodontal therapy Plaque related disease. Stannous Fluoride: - Reduce plaque (gingivitis). - Reduce enamel solubility. - Antibacterial (specific). - Reduce dental hyper sensitivity.
- 13. Types of Patients Type I : (periodontally healthy patient) Treatments: 1- Decrease of dental sensitivity. 2- Reduce plaque volume and age. 3- Reduce deleterious effects of pathogen. 4- Increase retention of fluoride in dental plaque. Long term high conc. Of fluoride (dentifrices, mouth rinses, gels)
- 14. Type II patients Periodontal treatments. Control of plaque pathogens. Reduce plaque volume. Reduce post operative sensitivity. Prevents of root caries.
