Summary
Hemifacial microsomia (HFM) affects tooth size and morphology. Patients with HFM exhibit smaller teeth on the affected side, with severity correlating to tooth size asymmetry.
Area of Science:
- Craniofacial biology
- Dental morphology
- Genetics
Background:
- Hemifacial microsomia (HFM) is a congenital condition affecting facial development.
- Understanding its impact on dental structures is crucial for treatment planning.
Purpose of the Study:
- To investigate the effects of HFM on tooth size and morphology.
- To correlate the severity of HFM with dental anomalies.
Main Methods:
- Mesiodistal tooth diameter was measured in 40 HFM patients using a vernier gauge.
- Measurements from affected sides were compared to contralateral sides.
Main Results:
- Teeth on the affected side of HFM patients were significantly smaller.
- Greater HFM severity correlated with increased tooth size asymmetry.
- Tooth morphology was also notably altered in HFM individuals.
Conclusions:
- HFM demonstrably impacts both tooth size and morphology.
- Dental asymmetry in HFM is linked to the condition's severity.

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.

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...

01:22Sutures 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...
