Study Notes
Interim and Temporary Restorations
- Interim restorations are placed after the previous restoration or caries have been removed at the start of endodontic treatment
- They provide structural integrity to the tooth while endodontic treatment is underway.
- They are expected to remain in place until the final restoration is completed
- They often support weakened cusps, preventing fractures between appointments
- They provide a good coronal seal
Temporary Restorations
- Temporary restorations are placed within an endodontic access cavity, often after removing an interim restoration
- Temporary restorations have a shorter duration than interim restorations.
- Key properties include ease of removal at the next appointment, affordability, and less desirable aesthetics.
- Removing them should not require further removal of tooth structure.
Reasons for Pre-Endo Build Up
- Simplifies rubber dam isolation for subsequent endodontic visits
- Creates space for prolonged irrigation solutions
- Allows for effective inter-appointment temporization, avoiding bacterial microleakage and gingival ingrowth
- Prevents fractures in weakened teeth, maintaining reference points
- Enhances patient acceptance during treatment
- Facilitates post-endodontic restoration
Sequence of Clinical Steps
- History
- Clinical and radiographic examination
- Informed consent
- Local anesthetic
- Rubber dam placement
- Restorability assessment
- Decision to save or not
- Decision of clinical approach until definitive restoration is placed
- (Sequence of clinical steps)
Possible Areas of Bacterial Penetration
- Through temporary bulk material
- Interim and temporary interface
- Temporary and tooth interface
- Proximal box (tooth interim interface)
Materials
- 3M ESPE Cavit, Cavit W, Cavit G: Temporary filling materials that self-cure under humidity. Cavit G is the hardest and can be removed in one piece.
- IRM (Dentsply Sirona): Intermediate restorative material intended to remain in place for up to one year. It is useful for hypersensitive tooth pulp. Offered in powder/liquid or capsule form.
- Materials for Endodontic Access Cavities
- GC Capsule Activation Instructions Method of using GC materials involves specific steps: shaking, plunger depressing, and mixing.
- F00 (Zero Flow), F03 (Low Flow): Dental materials for various restorative applications. Likely used for restorations.
- Orthodontic Bands: Used for applying force to move teeth.
- Copper Bands: Used in restorations with a lack of coronal structure.
Materials - Other
- Caviton EX, Neodyne-a, Shofu Base Cement, Evadyne Plus, Nishika Plast Seal Quick: Various temporary stopping materials.
- Eastman UCL: A specific type of temporary restoration material.
Case Discussion / Examples of Research Experiments
- Multiple cases and studies were discussed. Information like Caries excavation, Access sealed with GP point, Pre-endodontic build up using composite resin, Rubber dam application, Initiation of root canal are included in some case presentations.
- Different types of restorations and clinical steps are demonstrated for both anterior and posterior teeth.
- Research experiments and clinical trials related to coronal bacterial penetration, thickness of restorative material at the proximal tooth-restoration interface were discussed.
Preventing Coronal Leakage in Endodontically Treated Teeth:
- Pre-endodontic tooth preparation
- Thoroughness of Root canal obturation technique
- Temporary seal of root canal system, during and after treatment
- Choice and integrity of final tooth restoration
- Timeliness in restoration and establishment of atraumatic occlusion
- Long-term follow up to evaluate integrity of definitive treatment
- Thickness of material for seal
