Tooth replantation as an alternative to tooth extraction of periapically infected teeth

Abstract EN

The goal of this research is to collect data from previous researches to determine if the periodontal ligaments are able to regenerate on the surface of the root in a root canal treated tooth in the presence of periapical infection after replantation.

Previous researchers have shown that periodontal ligaments can regenerate on the root surface of non-infected avulsed teeth under specific conditions (e.g., time and mineralization) (Andreasen, 1995) (Ferrazzano, 2010).

Antibiotics or other antimicrobial drugs kill anaerobic bacteria or arrest their multiplication can be used in RCT to assist the natural defense process to combat infection and promote healing.

Some examples for these antibiotics are: metronidazole tablets, amoxycillin caps, and erythromycin tablets (Lewis MAO, 1986) (Hamanaka, 2015).

The hypothesis rests on the fact that the first part of healing in periapical abscess depends on removing the cause and the second part of healing depends on the immune system and tissue repair.

using treatment of wide-spread periapical infection so can utilize the natural tooth instead of implanting an artificial tooth.

In future researches, I advise using further investigation methods like histological biopsies from the surface of root in periapically infected teeth to verify periodontal ligament regeneration instead of depending on radiographic pictures only.
