Advanced Dental Admission Test (ADAT)

Which of the following describes a typical oral sign of Paget's disease?

1. Megaesophagus

2. Enlarged maxilla or mandible

3. Oral fibromas

4. Periodontal disease

The correct answer is: Enlarged maxilla or mandible

Paget's disease, also known as osteitis deformans, primarily affects the bone remodeling process, leading to abnormal and excessive bone formation. In the context of oral health, a typical manifestation of Paget's disease is the enlargement of the maxilla or mandible. This occurs due to the excessive bone turnover that characterizes this condition, resulting in an enlargement of the jawbones. Patients may present with expansion of the facial skeleton, which can be visually evident, and this can also affect occlusion and result in dental complications. Enlarged maxilla or mandible is not only a direct physical change but can also lead to misalignment of teeth, issues with dentures for those who wear them, and discomfort due to the altered structure of the jaw. This characteristic presentation can help clinicians identify Paget's disease during a dental examination, making it a crucial aspect of the disease's oral signs.
