[ Ссылка ] Internal root resorption is the progressive destruction of intraradicular dentin and dentinal tubules along the middle and apical thirds of the canal walls as a result of clastic activities.
Treatment for internal resorption includes root canal therapy, followed by restoration. Considering that vital pulp tissue is necessary for resorption, root canal therapy will stop the resorption. The chemical cleaning aspect of root canal therapy typically involves using various concentrations of sodium hypochlorite.
External resorption is more common than internal resorption. Decay usually happens from the outside in. It's a natural process your body uses to degrade your primary teeth in your youth, making room for your permanent teeth. However, when it affects your permanent teeth, it may cause long-term damage.
External resorption is often caused by injuries to the mouth and teeth that cause swelling and loss of bone and tissue on and around a tooth. Such injuries may occur from prolonged use of orthodontic appliances such as braces, or from tooth grinding or tooth bleaching.
