Summary
This study traces the evolution of the human stomatognathic apparatus, specifically dental arch shape, across different historical periods in Romania. Genetic factors and dietary habits influenced these changes, leading to the modern paraboloid dental arch form.
Area of Science:
- Paleoanthropology
- Craniometry
- Dental Anthropology
Context:
- Investigates the morphological evolution of the stomatognathic apparatus.
- Examines changes in skull and dental arch morphology over time.
- Utilizes historical skull samples from Romanian territory.
Purpose:
- To assess the possibility of prognostication regarding the morphologic aspect of the passive component of the stomatognathic apparatus.
- To analyze changes in maxilla, mandible, and facial morphology across different historical periods.
- To compare findings with existing literature data.
Summary:
- Analyzed 20 skulls from the 1st century AD, Middle Ages, and 20th century found in Romania.
- Observed a transition from prognathic, narrow dental arches in Neolithic skulls to rounded skulls with upsiloid and later paraboloid dental arches.
- Modern dental arches are semielliptical (maxilla) and parabolic (mandible).
Impact:
- Demonstrates the influence of genetic factors and dietary habits on masticator apparatus evolution.
- Explains the development of paraboloid dental arches due to gene flow between local and migratory populations.
- Provides insights into the long-term adaptation and changes in human craniofacial morphology.

The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...

Teeth
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...
