Study Notes

Isolation in Endodontics

Rubber dam application is considered the standard of care.
Advantages of rubber dam include:
- protection for the patient
- creating an aseptic environment improving vision
- making treatment more efficient
- protecting soft tissues from laceration
- preventing swallowing or aspiration of instruments and materials
Important considerations with isolation include protection for the dentist and assistant from aerosols.
Isolation limits transmission of systemic diseases, such as COVID-19, AIDS, hepatitis, and tuberculosis.
Dental healthcare personnel should wear eye protection and N95 respirators during patient encounters to protect from exposure to potentially contagious substances.
Proper use of dental dam kit includes:
- different clamps
- forceps
- puncher
- frame

Rubber Dam Retainers

Various styles and shapes of retainers exist.
Recommended retainer selection:
- Anterior teeth: Ivory #9, #212
- Premolars: #0, #2
- Molars: #14, #14A, #56
Winged clamps are preferred for their ability to be used as a single unit during single tooth isolation to create broader buccal-lingual deflection from the isolated tooth for better access. A disadvantage is that they can interfere with radiographic interpretation of files/cones
Universal clamp designs include
- Ivory "Butterfly" #9: small beaks, deep reaching, can be applied to most teeth
- Ivory #56: used for isolating molars
Additional designs include:
- Deep reaching clamps
- Serrated clamps for cases with minimal coronal structure

Preparation for Rubber Dam Placement

Identify the tooth requiring treatment.
Remove any caries or defective restorations.
Perform any additional procedures needed for rubber dam placement.

Isolation of Teeth with Inadequate Coronal Structures

Ligation: appropriate for young patients with unerupted teeth.
Deep reaching clamps are used when tooth structure extends below the gingival tissues but there is adequate structure above the crestal bone.
Bonding: missing tooth structure, including the natural height of contour, may necessitate bonding resin to increase retention on lingual or facial surfaces.
Clamping the Gingiva: is needed when loss of tooth structure extends below the gingival tissues, even below the crestal bone.

Application Techniques

Single motion techniques involve placing the clamp, rubber dam, and frame together.
Double motion involves first placing the clamp and rubber dam then the frame.

Techniques for Special Situations

Multiple adjacent teeth may require treatment with multiple clamps.
Insufficient tooth structure or porcelain crowns may require split dam techniques.
Bridge abutments, splints, orthodontics often need specialized approaches involving punching a larger-than-normal hole in the dam and use of liquidam for extra isolation.

Disinfection of The Operating Field

Remove plaque using rubber cup and pumice.
Place rubber dam.
Scrub tooth surfaces and surrounding rubber dam with 30% hydrogen peroxide.
Swab surfaces with 5% tincture of iodine or sodium hypochlorite.

Replacement of Coronal Structure

Temporary restorations use restorative materials like IRMs, GIC, and resins.
Bands can cemented, replacing missing tooth structure with IRMs.
Provisional crowns may need to be removed for treatment to improve visibility then replaced later.

Corrective Surgery

Gingivectomy: loss of tooth structure extends below the gingival tissues but crestal bone is adequate.
Crown lengthening procedures may involve making intrasulcular incisions to allow for osseous recontouring.
Orthodontic extrusion may be necessary for cases of inadequate tooth structure to allow for proper isolation.

Conclusion

Emphasize the need for patient and provider eye protection when working with calcium hydroxide to prevent eye contamination which can potentially cause blindness and other eye-related complications.
If calcium hydroxide is splashed into the eye, immediate eyelid flushing with copious water followed by a prompt ophthalmologic consultation are vital.
Always use a rubber dam in endodontics to prevent contamination.

Additional Considerations

Alkali burns are typically more serious than acid burns in endodontics .
Proper technique in using the rubber dam is needed to maintain 4-point contact with the tooth. Using clamps that are too large or too small may result in tissue damage.
