Pulpectomy and RCT in Primary Teeth (easy)

Conditions that make root canal treatment (RCT) on a primary molar unsuitable.

A primary molar crown that cannot be effectively repaired or filled.

Opening the pulp chamber to reach the root canals during RCT.

Process of cleaning and shaping the root canals in primary teeth.

An accidental hole in the root during RCT.

Small canals in addition to the primary canals in a tooth's root.

The Tip of the root, visible on X-rays.

Root canal treatment completed in a single appointment.

Endodontic files used for cleaning root canals range from file number 30 to 35, generally 21mm long.

Initial working length of the root canal is determined by x-ray, then verified by feeling the apical stop.

Root canals are cleaned with solutions like chlorhexidine or sodium hypochlorite, followed by normal saline.

Sodium Hypochlorite is a strong tissue irritant and should be used carefully, especially in children, and kept from extruding beyond the apical portion of the canal.

Root canals are dried with sterile paper points after irrigation with normal saline.

Common irrigating solutions include chlorhexidine and sodium hypochlorite (with caution), followed by normal saline.

Filling materials and their corresponding instruments are used to fill the canals after cleaning.

Avoid extra shaping of the canal to prevent tooth damage and perforations.

An antiseptic compound used in endodontic pastes (for root canal treatments). It helps to kill bacteria and prevent infection.

A material used in endodontic pastes. It helps to stimulate the formation of dentin (the hard tissue of the tooth) and can aid in healing.

An ingredient found in some endodontic pastes. It provides a sealing effect and can help to protect the root canal.

A key ingredient in many endodontic pastes. It has antibacterial properties and can help to soothe the tooth after treatment.

A special brush-like instrument used to introduce endodontic paste into a root canal.

Common materials for primary teeth's root canal filling include zinc oxide-eugenol paste, calcium hydroxide-iodoform mix, and materials like Metapex and Maisto's paste.

Thick root canal filling pastes, like ZOE, are inserted and condensed using root canal pluggers.

Thinner pastes, like iodoform or calcium hydroxide, are inserted with a spiral Lentulo attached to a slow-speed engine.

Certain root canal filling materials are inserted using plastic syringes and tips provided by the manufacturer.

The ideal root canal filling material should resorb at the same rate as the root, be safe for tissues, readily resorbs if misplaced, is antiseptic, easy to use, non-shrinking, and removable.

A combination of Calcium Hydroxide and Iodoform is considered a good material for primary root canals because it provides a high pH environment and has bacteriostatic effects.

Calcium Hydroxide creates a high pH environment (above 10) in the root canal which helps in killing bacteria.

Iodoform, combined with Calcium Hydroxide, contributes to the bacteriostatic effect by preventing bacterial growth in the root canal.

Root canal treatment in primary teeth is generally successful, with rates ranging from 80% to 95% depending on the technique and filling material used.

Zinc Oxide Eugenol (ZOE) is a common filling material used in primary tooth root canal treatments, contributing to high success rates.

Kri Paste is a special filling material used in primary tooth root canal treatments, resulting in high success rates (over 80% to 95.6%).

Root canal treatments in primary anterior teeth are generally successful, with rates ranging from 76% to 82.8%.

Earlier techniques for primary tooth RCT had lower success rates (around 53%) compared to modern techniques using ZOE or Kri Paste, which achieve much higher success rates.

A white, creamy paste used in root canal treatment. It has antibacterial properties and helps promote healing. It is often used as a temporary filling until the root canal is permanently sealed.

A specialized instrument used in root canal treatment to place calcium hydroxide paste or other medications into the root canal. It is made of a helix-shaped wire that helps distribute the paste evenly.

A needle-like instrument used to precisely inject dental materials like calcium hydroxide paste into the root canal. It allows for controlled delivery and placement.

The vehicles used to carry calcium hydroxide paste can be Aqueous, Viscous, or Oily. Aqueous leads to rapid depletion, viscous provides lower solubility, and Oily has the lowest solubility and diffusion.

Kri paste demonstrates stronger antibacterial effectiveness compared to ZOE (Zinc Oxide Eugenol)

Filling materials like calcium hydroxide paste or Kri paste are used to seal the root canal and prevent bacteria from entering. They also help promote healing and prevent the formation of an abscess.

The speed at which root canal filling material dissolves or breaks down over time.

It's essential to consider the rate of tooth resorption when choosing root canal filling materials, especially in primary teeth, as they will eventually be replaced by adult teeth.
