Summary
External tooth resorption, often caused by trauma, can be managed with calcium hydroxide. However, complex cases, especially combined internal and external resorption, may require extraction due to advanced lesions.
Area of Science:
- Dentistry
- Endodontics
- Oral Pathology
Background:
- External tooth resorption (ETR) is a pathological process often initiated by trauma to the periodontal ligament.
- ETR can be histologically and clinically classified into five distinct categories.
- The alkaline pH of calcium hydroxide has been utilized to mitigate the progression of resorption.
Observation:
- This article presents five case reports detailing the clinical presentation and management of ETR.
- Combined internal and external resorption presents unique management challenges.
- The severity of resorption lesions significantly impacts treatment outcomes.
Findings:
- Successful management of ETR was achieved in two out of the five presented cases.
- Three cases necessitated tooth extraction due to the advanced stage of the resorption process.
- The efficacy of calcium hydroxide in managing ETR was observed, though not universally successful in advanced cases.
Implications:
- Understanding ETR classification is crucial for effective treatment planning.
- Calcium hydroxide remains a valuable intracanal medicament for managing ETR.
- Early diagnosis and intervention are key to improving prognosis for external tooth resorption, with extraction being a last resort for advanced lesions.

01:15Teeth
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 and...

01:21Tooth Anatomy
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 grinding food.
