Study Notes
Understanding Dental Anomalies: A Multifactorial and Multilevel Aetiology
- Dental anomalies can occur during tooth development or post-development and are classified based on shape, size, number, location, and structure.
- Dental anomalies have a multifactorial aetiology, including genetic, epigenetic, environmental, and unknown causes.
- More than 300 genes are involved in dental development, regulating key transcription factors that determine the number, type, size, shape, and tissue formation of teeth, as well as the mineralisation of enamel and dentin.
- Alterations in gene expression during the initiation and morphogenesis phases of tooth development can lead to anomalies in tooth number, size, and shape.
- Differentiation of enamel and dentin occurs in the bell stage of tooth formation, and defects in enamel and dentin can result from genetic mutations.
- Amelogenesis imperfecta is a genetic condition that affects enamel formation, causing alterations in enamel formation in the hypoplastic, hypocalcified, or hypomature phases.
- Environmental factors can also contribute to the formation of dental anomalies, with the severity and duration of the insult, stage of development, and host susceptibility affecting the clinical expression.
- Some dental anomalies, such as regional odontodysplasia, have an uncertain aetiology, affecting one region of the oral cavity where some or all dental structures are missing or irregularly formed.
- The incidence of dental anomalies is high in the population, with impaction being the most common, followed by root dilaceration and hypodontia.
- Dental anomalies are less common in primary dentition than in permanent dentition.
- Some dental conditions can present in both primary and permanent dentitions.
- Understanding the complex aetiology of dental anomalies, including genetic, epigenetic, environmental, and unknown factors, is essential for accurate diagnosis and effective treatment.
