Summary
Odontogenic sinus tract stoma locations are misleading in 80% of cases, often shifting between teeth. Patient age correlates with shift distance, necessitating careful radiographic evaluation.
Area of Science:
- Dentistry
- Radiology
- Oral Surgery
Background:
- Odontogenic sinus tracts present a diagnostic challenge.
- Accurate localization of the radiographic source is crucial for effective treatment.
Purpose of the Study:
- To evaluate the spatial relationship between clinical stoma site and radiographic source of odontogenic sinus tracts.
- To determine the distribution of stoma locations and patient factors predicting shift.
Main Methods:
- Prospective study of 100 patients with draining intraoral sinus tracts.
- Gutta-percha (GP) cone tracing into tracts followed by periapical radiography.
- Statistical analysis using non-parametric and chi-square tests.
Main Results:
- 80% of patients exhibited stoma shift from the radiographic source.
- The most common shift was 0.5 units (between adjacent teeth) in 61.3% of shifted cases.
- Patient age showed a moderate correlation with shift distance (P < .05).
Conclusions:
- Sinus tract stoma location is frequently misleading, requiring radiographic confirmation.
- A 0.5-unit shift is the most common displacement pattern.
- Clinicians should consider patient age and utilize GP cone tracing for accurate diagnosis.

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.
