[The evolutionary development of the jaws and dentition]
Abstract:
The development of the jaws and dentition during half a billion years of evolution is described in broad lines and two theories regarding the origin of the dentition are discussed in detail. It is highly likely our dentition developed from dermal ossification 'denticles' originally protecting, in particular, the head of primitive extinct vertebrates. Simple, at first tubercular, later conical teeth developed into complex tooth and molar forms, especially in mammals. Special attention is given to the development of molar cusps. The process of continuous replacement of the dentition is also discussed in more detail.

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...
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...

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
