Supernumerary teeth are commonly associated with which condition?

• A. Marfan syndrome
• B. Cleidocranial dysplasia
• C. Dentinogenesis imperfecta
• D. Ectodermal dysplasia

Answer: (B)

Supernumerary teeth, which are additional teeth that develop beyond the normal count, are most commonly associated with cleidocranial dysplasia. This genetic condition is characterized by the underdevelopment or absence of the clavicles, which can lead to various dental anomalies, including the formation of supernumerary teeth. Individuals with cleidocranial dysplasia often exhibit a range of dental issues due to the altered development of the jaws and maxillary structures, leading to more widespread occurrence of extra teeth.

In contrast, while other conditions like Marfan syndrome, dentinogenesis imperfecta, and ectodermal dysplasia have unique dental manifestations, they are not primarily associated with the presence of supernumerary teeth. Marfan syndrome is more related to connective tissue abnormalities and has less of a direct impact on dental eruption patterns. Dentinogenesis imperfecta affects the quality of dentin and results in discolored teeth and increased fragility, but it does not typically lead to supernumerary teeth. Ectodermal dysplasia is associated with abnormal development of ectodermal structures, which can result in missing teeth or hypodontia, rather than the development of excess teeth. Hence, the link between supernumerary teeth and cleidocr
