True or false: Posterior composites are excellent for small to medium-sized restorations but extremely difficult to get a good result with very large restorations.
True
True or false: The biggest single contraindication for posterior composites is when good access, visibility, and isolation cannot be achieved.
True
True or false: Every textbook in operative dentistry will say that the number one contraindication for using composite is when good access, visibility, and isolation cannot be achieved.
True
True or false: If composite isn't indicated, other alternatives such as amalgam, ceramic inlays, or on laser crowns should be considered.
True
True or false: Some people believe that if a rubber dam cannot be placed, composites should not be used.
True
True or false: The speaker works at a private practice one day a week and had to take care of a restoration on the distal of tooth number two for their last patient.
True
Composite restorations are less time-consuming and technique-sensitive compared to amalgam restorations.
False
Amalgam restorations are quicker to perform and less technique-sensitive than composite restorations.
True
Amalgam has ongoing improvements and developments, unlike composite materials.
False
Composite materials, including matrix systems and bonding agents, have not evolved or improved over time.
False
The initial posterior composites, like P10 from 3M, were of high quality and did not require improvement.
False
The lecturer discusses isolation using a rubber dam before addressing diagnosis and treatment planning.
False
Proper isolation for class one or class two composite restoration involves 4-5 teeth anterior and 3-4 teeth posterior to the tooth being worked on.
False
Non-latex rubber dam should be used for patients allergic to latex during composite restoration.
True
The use of wax floss ligature and clamp is not necessary for safety during composite restoration.
False
Minimally invasive dentistry means never removing any healthy tooth structure.
False
Convenience form is not necessary for accessing proximal lesions while preserving healthy tooth structure.
False
It is important to have a good reason for removing healthy tooth structure during crown preparation.
True
GV Black was a revolutionary in dentistry during the early 1900s.
True
Enamel can regenerate and grow back.
False
GV Black believed that caries would have been eliminated by now.
False
Webb first published the term extension for prevention in the 1870s.
True
An ideal Mo prep for composite restorations is the same for all teeth.
False
The most vulnerable part of any restoration is the occlusal surface.
False
The only requirement for prepping pits and fissures for composite is if there is a problem such as caries or old restorations.
True
Enamel bonding is graded as a ten on a scale of 1 to 10.
True
The concept of extension for prevention in composite preparation was historically introduced by a person named Webb.
True
Extension for prevention always requires breaking gingival contact for composite restorations.
False
Extension for prevention should be tailored based on the patient's caries risk.
True
The palpable floor depth determines the depth of the pits and fissures for a class one or the occlusal portion of a class two restoration.

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
