Study Notes
Dental Caries and Bacteria
- Prevalent Bacteria: Actinomyces, Streptococcus mutans, and Lactobacilli are key bacteria involved in the development of dental caries.
Embrasures
- Definition: Embrasures are the spaces between adjacent teeth.
-
Classes of Embrasures: There are three classes of embrasures which differ in shape and characteristics.
- Class 1: Normal embrasure space; best cleaned with floss.
- Class 2: Characterized by loss of papillae without bone loss; interdental brushes are the most effective cleaning aid.
- Class 3: Larger spaces with recession and bone loss present.
Interdental Aids
- General Guidance: Interdental aids should fill the embrasure space and be slightly larger.
- Best Aids: Water pic is ideal for bridges and implants, while superfloss is suggested specifically for bridges.
Furcations
-
Classes of Furcations: Four classes indicating the extent of probe accessibility and recession presence.
- Class 1: Small indentation detectable with an instrument.
- Class 2: Probe partially enters the furcation.
- Class 3: Probe completely enters the furcation.
- Class 4: Probe completely passes through the furcation with visible recession.
Implants and Biological Considerations
- Biological Seal: It refers to soft tissue sealing around the implant, which is essential for implant health.
- Osseointegration: Describes the successful union between bone and an implant without mobility, indicating a successful integration.
Fluoride Usage
- Inhibition of Bacterial Activity: Fluoride inhibits bacterial activity immediately upon application.
- Topical vs. Systemic: Systemic fluoride promotes mineralization of developing teeth through dietary sources, while topical fluoride aids in enamel maturation after eruption.
- Surface Preferences: Fluoride bonds more effectively to smooth surfaces than to rough surfaces.
Emergency Procedures
- Treatment for Acute Toxic Fluoride: Induce vomiting, contact emergency services, use fluoride bonding agents like milk, and follow basic life support procedures.
Oral Health Assessments
- Productivity: Effectiveness in oral health can be gauged by the efficiency of biofilm removal.
Interdental Space Considerations
- Selecting Interdental Aids: Factors include furcations, embrasures, and user dexterity.
Volatile Sulfur Compounds (VSC)
- Cause of Halitosis: VSCs, which form as oral microorganisms degrade proteins, are the primary contributors to bad breath.
Oral Hygiene Tools
- Stim-U-Dent: Effective for cleaning interdental areas with exposed root surfaces.
- End Tuft Brush: Suitable for hard-to-reach areas, such as crowded teeth and open embrasures.
- Charters Method: Beneficial for cleaning around orthodontics and for various restorations.
Fluoride Regulation and Sources
- Regulatory Bodies: Bottled water regulation is handled by the FDA, while tap water is regulated by the EPA.
- Fluoride Sources: Obtained through food, fluoridated water, and processed foods.
Fluoride Benefits and Risks
- Fluorosis: Results from excessive fluoride absorption during tooth development, resulting in enamel defects such as white flecks and pitting.
- Fluoride Forms: Includes sodium fluoride, acidulated phosphate fluoride, and stannous fluoride, each with distinct applications and effectiveness.
Conclusion on Fluoride
- Fluoride's Role: Facilitates remineralization by attracting calcium and phosphate into the tooth structure, boosting resistance to decay.
Special Techniques and Aids
- Fluoride Treatments: Professional treatments can utilize gels, foams, and varnishes, each with varying ppm levels to maximize efficacy.
- Substantivity: Describes fluoride’s ability to bind to the pellicle, biofilm, and tooth structure, allowing gradual release over time for sustained benefit.
