Study Notes
Dental Lecture on Class One and Class Two Composite Restoration
- Importance of good isolation for class one or class two composite restoration
- Contamination control crucial after etching with phosphoric acid and before applying primer
- Benefits of good isolation: visibility, access, patient safety, and minimizing aerosol
- Use of non-latex rubber dam for patients allergic to latex
- Ideal isolation involves 2-3 teeth anterior and 1-2 teeth posterior to the tooth being worked on
- Wax floss ligature and clamp used for safety in case the clamp falls back in the mouth
- Emphasis on isolating enough teeth for good access and visibility without overdoing it
- Properly inverted rubber dam with material snapped through all contacts for effective isolation
- Minimally invasive dentistry means never removing healthy tooth structure without a good reason
- Convenience form necessary for accessing proximal lesions while preserving healthy tooth structure
- Importance of having a good reason for removing healthy tooth structure during crown preparation
- Reflection on the first experience of removing healthy tooth structure for a crown preparation
Extension for Prevention in Dental Restorations
- Webb first published the term "extension for prevention" in the 1870s
- Extension for prevention aims to place restoration margins in easy-to-clean areas to prevent secondary caries
- The most vulnerable part of any restoration is the margin, particularly the gingival margin of a class two restoration
- Dirty places in the mouth, such as non-coalesced fissures and plaque niches, are likely sites for caries to develop
- In high caries risk patients, the entire mouth is considered a dirty place
- Enamel bonding for class one or class two composites is highly effective and durable
- Enamel bonding is rated as outstanding, with restorations lasting 30-40 years
- The decision to follow extension for prevention depends on the caries risk of the patient
- High caries risk patients may require more aggressive preparation to place margins in easy-to-clean areas
- Low caries risk patients may not need to break contact or remove healthy tooth structure for extension for prevention
- Customizing extension for prevention based on the patient's caries risk is a minimally invasive approach
- The depth of preparation in pits and fissures for class one or occlusal portion of class two restorations depends on the caries depth and the determination of the pulpal floor
