Congenitally missing maxillary primary canines: report of three cases
International Journal of Paediatric Dentistry
|October 4, 2006
Summary
Congenital missing maxillary canines in primary teeth are rare. Permanent dentitions in these children may exhibit varied anomalies, including hypodontia and hyperdontia.
Area of Science:
- Pediatric Dentistry
- Dental Genetics
- Oral and Maxillofacial Surgery
Background:
- Hypodontia, the congenital absence of teeth, is infrequent in primary dentition.
- Lateral incisors are the most commonly missing primary teeth.
- Primary canine hypodontia is exceptionally rare.
Observation:
- Presents three cases of primary dentition hypodontia exclusively affecting maxillary canines.
- Two cases also exhibited hypodontia and hyperdontia in permanent dentitions.
- All three cases showed normal development of permanent canines.
Findings:
- Congenital maxillary canine absence in primary teeth is a rare condition.
- Associated permanent dentition anomalies can range from missing teeth (hypodontia) to extra teeth (hyperdontia).
- Normal development of permanent canines can occur despite primary canine absence.
Implications:
- Highlights the diverse range of dental anomalies associated with primary maxillary canine hypodontia.
- Suggests careful monitoring of permanent dentition development in children with primary canine hypodontia.
- Informs diagnostic and treatment planning for dental anomalies involving canine development.

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...

Tooth 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.

Incomplete 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.
