Summary
Severe incisor root resorption (SIRR) linked to impacted canines is rare. Female patients with enlarged dental follicles and normal lateral incisors face a significantly higher risk, necessitating careful screening.
Area of Science:
- Dentistry
- Orthodontics
- Oral Surgery
Background:
- Severe incisor root resorption (SIRR) associated with impacted maxillary canines is an uncommon but significant clinical concern.
- Early identification and management of SIRR are crucial for preserving dental health.
Purpose of the Study:
- To investigate and identify predisposing factors for SIRR specifically linked to impacted maxillary canines.
Main Methods:
- A comparative analysis of clinical and radiographic data from 55 patients with SIRR and 96 impacted canines against 57 control subjects.
- Variables assessed included patient age and sex, canine impaction position, dental follicle size, and lateral incisor anomalies.
Main Results:
- SIRR predominantly affected lateral incisors, with bilateral occurrences being frequent.
- Significant associations for SIRR included female sex, canine displacement in the middle third of incisor roots, enlarged dental follicles (>2 mm), and normal lateral incisors.
- Multivariate analysis revealed increased SIRR risk in females (4.2x), those with enlarged follicles (8.3x), and normal lateral incisors (5.8x).
Conclusions:
- Female patients with enlarged dental follicles and normal lateral incisors require vigilant screening for SIRR.
- The degree of canine displacement may also correlate with the risk of developing SIRR.

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...
