Summary
External root resorption (ERR) caused by embedded teeth (et-ERR) in asymptomatic teeth can often be managed without root canal therapy. Prompt extraction of the embedded tooth may preserve pulp vitality, allowing for follow-up observation.
Area of Science:
- Endodontics
- Oral Surgery
- Periodontology
Background:
- No established guidelines exist for managing asymptomatic teeth with external root resorption (ERR) caused by embedded teeth (et-ERR).
- Current practice often involves prophylactic or concomitant root canal therapy (RCT) with embedded tooth extraction.
Purpose of the Study:
- To report the prognosis of external root resorption (ERR) in asymptomatic teeth.
- To investigate the possibility of preserving the vital pulp of teeth with ERR.
Main Methods:
- Retrospective case series of patients with asymptomatic et-ERR.
- Included extraction of the embedded tooth.
- Follow-up included clinical and radiographic examinations to assess symptoms, vitality, and adverse events.
Main Results:
- Three out of four cases preserved pulp vitality after embedded tooth extraction without additional intervention.
- Radiographic evidence showed bone and periodontal tissue regeneration.
- One case required intentional replantation due to loss of pulp vitality.
Conclusions:
- Prompt, minimally invasive extraction of embedded teeth with effective infection control can preserve pulp vitality in et-ERR teeth.
- Observation without prophylactic RCT is a viable management strategy for asymptomatic et-ERR teeth.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
