Idiopathic failure of eruption of permanent molar teeth
Oral Surgery, Oral Medicine, and Oral Pathology
|August 1, 1976
Abstract:
Failure of permanent teeth to erupt without any known cause is a seldom occurring phenomenon. However, it brings to light our ignorance of the basic physiologic mechanism of tooth eruption. In this article we present five patients with unerupted permanent molar teeth. In all instances, no obvious cause exists. Indications for operative intervention and management are discussed, but the cases are also presented to focus attention on our lack of knowledge of the physiology of tooth eruption.

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.
