Summary
Tooth survival after root canal treatment is crucial. While restoration type may influence outcomes, factors beyond infection control significantly impact long-term tooth retention and function.
Area of Science:
- Endodontic Treatment Outcomes
- Dental Prognosis
- Restorative Dentistry
Background:
- Assessing endodontic treatment success involves various outcome measures, including periapical tissue health and tooth survival.
- Epidemiological data suggest a high prevalence of root-filled teeth with persistent apical periodontitis, indicating patient and dentist acceptance of retained teeth.
- Prognostic factors may differ based on the chosen outcome measure, emphasizing the importance of understanding both infection control and tooth retention.
Purpose of the Study:
- This narrative review focuses on tooth survival as the primary outcome following endodontic (root canal) treatment.
- To explore prognostic factors influencing the long-term retention of teeth that have undergone root canal therapy.
Main Methods:
- A narrative review methodology was employed.
- Literature search was conducted using the PubMed database.
Main Results:
- An estimated annual loss rate of approximately 2% for teeth undergoing root canal treatment was observed.
- Restoration of the tooth post-endodontic treatment has been the most extensively studied factor.
- While studies suggest indirect restorations may offer better survival than direct restorations, this remains inconclusive as a definitive prognostic factor.
Conclusions:
- The restoration of endodontically treated teeth is a critical area of research for improving tooth survival.
- Further investigation is needed to definitively establish the prognostic value of different restorative approaches on long-term tooth retention after root canal treatment.

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...

1.3K
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....
