Cleidocranial dysplasia is characterized by delayed dentition with multiple supernumerary teeth, often impacted. This condition also shows delayed closure of fontanelles, absent or hypoplastic clavicles, and multiple dental anomalies. Hypoparathyroidism, Pierre Robin syndrome, and Down syndrome do not typically present with multiple supernumerary teeth as a characteristic feature.
Square collimators are not commonly used in dentistry.
Myositis ossificans commonly involves the masseter muscle in the head and neck region. The masseter is the most frequently affected masticatory muscle, often following trauma or injury. This condition involves heterotopic bone and cartilage formation within muscle tissue. Hyoglossus, stylohyoid, and lateral pterygoid muscles are less commonly affected by myositis ossificans.
