What is a common dental consequence of hypophosphatasia?

• A. Acementosis
• B. Gingival hyperplasia
• C. Periodontal disease
• D. Malocclusion

Answer: (A)

Hypophosphatasia is a metabolic disorder characterized by a deficiency in the enzyme alkaline phosphatase, which plays a crucial role in the mineralization of bones and teeth. One of the primary dental manifestations of this condition is acementosis, which refers to the absence or deficiency of cementum, the calcified substance that covers the roots of teeth and attaches them to the periodontal ligament.

In individuals with hypophosphatasia, the lack of adequate cementum formation leads to problems such as increased tooth mobility, difficulty in tooth retention, and a higher likelihood of dental infections. This lack of cementum also contributes to the overall weakening of the tooth structure, making it susceptible to decay and loss.

While the other options may be relevant in some pediatric dental contexts, they do not directly correlate with hypophosphatasia in the same manner as acementosis, which is a specific consequence related to the enzymatic dysfunction involved in this condition. Therefore, understanding the mechanism behind hypophosphatasia and its direct effects on dentin and cementum formation is essential for recognizing the significance of acementosis in these patients.
