What is the pH for demineralization?
What is the pH for demineralization?
Demineralization is the process of tooth enamel losing minerals, making it weaker and more susceptible to cavities. This occurs when the pH of the mouth drops below 5.5.

What are the advantages of pre-endo buildup?
What are the advantages of pre-endo buildup?
Pre-endo buildup is a procedure where a filling material is placed on the tooth before root canal treatment. It strengthens the tooth, improves access for the procedure, and protects the root canal space.

What would you use for anesthesia for MB 36 moderate caries?
What would you use for anesthesia for MB 36 moderate caries?
A patient with moderate caries on the mesiobuccal surface of tooth 36 (lower right first molar) will require anesthesia to numb the area. The technique involves using a local anesthetic injection to block the inferior alveolar nerve, which supplies sensation to that tooth.

How to prevent coronal microleakage in endodontic treatment?
How to prevent coronal microleakage in endodontic treatment?
To prevent coronal microleakage, several measures are crucial during endodontic treatment:**
- Caries Removal: Thorough removal of any defective restorations or caries along with any remaining carious lesions.
- Temporary Filling Thickness: Keeping the temporary filling thin (no more than 2mm) to minimize space for leakage.
- Accurate Placement: Using a well-condensed temporary filling material, with a close adaptation to the tooth surface.
- Proper Restoration: Placing a permanent filling or crown after the endodontic treatment to ensure a tight seal.
Study Notes
Temporary vs. Interim Materials
- Temporary materials are quicker, cheaper, but have inferior aesthetics compared to interim materials.
- Interim materials last longer and provide a better seal for weakened teeth.
Radiographic Report
- The provided X-ray images are not visible to me.
- The report mentions various restorations, including Class I and Class II restorations and locations of caries lesions.
- Key structures like #17, #16, #46, #45 feature restorations and caries.
- Areas of concern include interproximal caries between teeth #16, #11, #150, and #14, as well as various other localized caries
Explorer Use in Dental Clinics
- Explorers evaluate proximal margins of restorations, removing excess cement and material.
- They check for caries lesions and any damage to the tooth structure.
- Also used for removing excess rubber material.
- Important in periodontal exams, examining furcation and root surfaces.
Teeth Requiring Extraction
- Impacted teeth need extraction to remove bone/tissue impediment.
- Accidents can cause needed teeth extraction.
- Fractured or broken teeth often mandate extraction.
- Periodontal diseases can cause need for extraction.
- Severe decay/damage reaching the pulp may necessitate extraction.
- Wisdom teeth, crowding can be reasons for extraction.

- Abrasion
- Abfraction
- Erosion
Final Restoration Options After Root Canal Treatment
- Full crown with a direct post
- Full crowning with an indirect post
- Direct composite restoration
- Full crown without a post.
Radiolucency in Dentin
- Radiolucency in outer 1/3 of dentin is often related to advanced stages of dental disease but not necessarily an aggressive dental stage.

- Amalgam promotes microleakage.
- Amalgam does not bond to tooth structure
- Amalgam preparation design requirements are minimal
- Amalgam is not an insulator
- Amalgam is associated with allergies for some.
