Summary
Root-filled teeth restored with posts showed a higher risk of developing apical pathology compared to those with composite restorations. Longer delays between endodontic and prosthetic treatment also increased disease progression risk.
Area of Science:
- Endodontics
- Restorative Dentistry
- Oral Radiology
Background:
- Post-endodontic restorations aim to protect root-filled teeth.
- Periapical status evaluation is crucial for assessing treatment outcomes.
- Understanding the impact of different restoration types on periapical health is important.
Purpose of the Study:
- To compare periapical status transitions in root-filled teeth after post placement versus other post-endodontic treatments.
- To evaluate the long-term radiographic outcomes of different restorative approaches following root canal therapy.
Main Methods:
- Retrospective longitudinal radiographic study of 284 patients.
- Teeth were categorized into Endo-fill, Endo-crown, and Endo-post groups.
- Periapical status assessed using the periapical index (PAI) and analyzed with multi-state Markov models.
Main Results:
- 7.7% of teeth developed apical pathology within 8 months.
- The Endo-post group showed a higher transition rate from healthy to diseased periapical status (10.78%) compared to Endo-crown (9.75%) and Endo-fill (4%).
- A delay exceeding 8 months between endodontic and prosthetic treatment significantly increased disease progression risk (HR 3.16).
Conclusions:
- Teeth restored with posts exhibited a higher risk of periapical disease progression compared to composite restorations.
- Timely prosthetic restoration after endodontic treatment is crucial for maintaining periapical health.
- Further controlled clinical trials with extended follow-up are recommended.

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...

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...
