Retention of posts in teeth with nonvital pulps
The Journal of Prosthetic Dentistry
|April 1, 1983
Abstract:
The results of this study indicate that: 1. Cast posts without grooves are more retentive when cemented with zinc phosphate than with composite resin. 2. Cast posts with grooves in the posts and adjacent grooves in the teeth are more retentive than cast posts without grooves. 3. Cast posts with grooves and with adjacent grooves in the teeth have equal or greater retention than Paraposts with grooves in the teeth when both are placed with composite resin.

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.
