Developmental disorders of the dentition: an update
Summary
Genetic factors cause common dental anomalies, affecting tooth development, formation, and eruption. This review explores isolated and syndromic causes, guiding clinical care for conditions like ectodermal dysplasias and Van der Woude syndrome.
Area of Science:
- Developmental biology
- Genetics
- Oral medicine
Background:
- Dental anomalies are frequent congenital malformations.
- These can manifest as isolated issues or part of broader genetic syndromes.
- Understanding genetic influences is crucial for clinical management.
Purpose of the Study:
- To review the genetic causes of abnormal tooth development.
- To discuss the clinical implications of these dental anomalies.
- To cover a range of conditions from tooth agenesis to supernumerary teeth.
Main Methods:
- Literature review focusing on genetic causes of tooth development.
- Analysis of findings from mouse and zebrafish models.
- Discussion of specific isolated and syndromic conditions.
Main Results:
- Genetic factors underlie various dental anomalies, including tooth agenesis, delayed formation/eruption, and abnormal size/shape.
- Syndromic causes discussed include Van der Woude syndrome, ectodermal dysplasias, and others.
- Supernumerary teeth causes, like cleidocranial dysplasia, are also reviewed.
Conclusions:
- Genetic insights into tooth development are essential for understanding and managing dental anomalies.
- This review provides a framework for diagnosing and treating patients with genetic dental malformations.
- Further research into genetic pathways can improve clinical care strategies.

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...

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...

01:28Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

01:16Psychosexual Stages of Personality: Oral
3.9K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:26Assessment of the Mouth
1.6K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
