Summary
This case study highlights a rare instance of 16 supernumerary teeth in a young female patient with congenital heart disease. Genetic factors are suggested as a significant influence on this dental anomaly, supported by family history.
Area of Science:
- Dentistry
- Genetics
- Pediatrics
Background:
- Supernumerary teeth, also known as hyperdontia, are a relatively common dental anomaly.
- Congenital cardiopathy is a structural defect of the heart present at birth.
- The etiology of supernumerary teeth is often multifactorial, involving genetic and environmental influences.
Observation:
- An 11-year-old Chinese female patient presented with 16 supernumerary teeth.
- The patient also had a diagnosis of congenital cardiopathy.
- The patient's mother exhibited the same clinical manifestation of supernumerary teeth.
Findings:
- A detailed family history investigation was conducted.
- The presence of multiple supernumerary teeth in a patient with congenital cardiopathy is a notable clinical observation.
- A familial pattern of supernumerary teeth was identified.
Implications:
- This case underscores the potential genetic basis for supernumerary teeth, particularly in syndromic cases.
- Further research into the genetic underpinnings of dental anomalies and their association with systemic conditions is warranted.
- Understanding genetic factors can aid in early diagnosis and management of dental anomalies.

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...

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...
01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

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.
