Summary
Dental agenesis, the congenital absence of teeth, is common in individuals with Crouzon syndrome. This study found a high prevalence and varied patterns of missing teeth in this population.
Area of Science:
- Dentistry
- Medical Genetics
- Oral and Maxillofacial Surgery
Background:
- Dental agenesis can be isolated or part of a syndrome.
- Crouzon syndrome is a craniosynostosis disorder.
- Dental agenesis patterns in Crouzon syndrome are understudied.
Purpose of the Study:
- To investigate dental agenesis prevalence.
- To analyze dental agenesis patterns in Swedish individuals with Crouzon syndrome.
Main Methods:
- Examined panoramic radiographs of 26 individuals with Crouzon syndrome.
- Excluded third molars from analysis.
- Classified agenesis patterns using the tooth agenesis code (TAC).
Main Results:
- 42.3% of individuals had at least one congenitally missing tooth.
- Second premolars were the most frequently absent teeth.
- Identified 11 unique, mostly asymmetric, dental agenesis patterns.
Conclusions:
- Individuals with Crouzon syndrome exhibit a high prevalence of dental agenesis.
- A significant variability in dental agenesis patterns exists.
- Awareness is crucial for orthodontic treatment planning in mixed dentition.

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...

01:23Cystic Fibrosis: Pathogenesis
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

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...

02:20Cohesins
Cohesin protein complexes are a molecular glue that holds two sister chromatids together. They play an important role both in mitosis and meiosis. In mitosis, all cohesin complexes present on the chromosomes are removed before the start of the anaphase stage.
Cohesin complexes in Meiotic Division
Meiosis involves two distinct rounds of chromosomal segregation and cell divisions— Meiosis I followed by Meiosis II – producing four daughter cells. Meiosis I includes the separation of homologous...
