Dental OSCE (Objective Structured Clinical Examination) Practice Exam

In the case of supernumerary teeth, which condition is associated with the presence of clavicles?

1. Cleidocranial dysplasia

2. Gardner's Syndrome

3. Osteogenesis Imperfecta

4. Hypohidrotic Ectodermal Dysplasia

The correct answer is: Gardner's Syndrome

The presence of supernumerary teeth can indeed occur in various conditions, but cleidocranial dysplasia is the specific condition most commonly associated with the presence of clavicular anomalies. This genetic disorder, which affects bone development, often presents with multiple dental anomalies, including supernumerary teeth. Individuals with cleidocranial dysplasia frequently display hypoplastic or absent clavicles, leading to characteristic changes in posture and shoulder mobility. In contrast, while Gardner's Syndrome is also associated with dental anomalies, such as supernumerary teeth and impacted teeth, it primarily involves the presence of multiple osteomas, skin tumors, and an increased risk of colorectal cancer, rather than clavicular issues. Osteogenesis Imperfecta relates to connective tissue disorders primarily impacting bone fragility, and hypohidrotic ectodermal dysplasia involves defects in sweat glands, hair, and teeth but not specifically clavicular development. Thus, cleidocranial dysplasia is the clear link between supernumerary teeth and abnormalities of the clavicles, emphasizing the dental manifestations commonly seen in this condition.
