Abstract:
The purpose of this study was to determine the prevalence of odontogenic sinus tracts in patients referred for endodontic therapy. Charts of 330 patients (393 permanent teeth) endodontically treated during a 10-month period were reviewed and data was collected. Among the 393 permanent teeth there were a total of 160 teeth with preoperative status of periradicular inflammation. Of 160 teeth with preoperative status of periradicular inflammation, 29 teeth (18.1%) had an odontogenic sinus tract, which correlates to almost one in five teeth with periradicular inflammation having a sinus tract.

Teeth
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...
Tooth Anatomy
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.
