What is meant by oro-antral communication in dentistry?

• A. A separation of the gum from the tooth
• B. A hole between the maxillary sinus and the mouth
• C. A lateral deviation of the jaw
• D. A complication from orthodontic treatment

Answer: (B)

Oro-antral communication refers specifically to an opening or pathological connection that develops between the oral cavity, particularly the maxillary sinus, and the mouth. This situation often arises following certain dental procedures, particularly the extraction of upper molars, where the roots of the teeth may extend into the maxillary sinus. In this context, the presence of an oro-antral communication can lead to complications such as sinus infections and issues with healing. The other options are related to different dental or oral conditions but do not accurately define oro-antral communication. The separation of the gum from the tooth pertains to a different condition known as gum recession or attachment loss. A lateral deviation of the jaw typically refers to issues related to jaw alignment or temporomandibular joint dysfunction. A complication from orthodontic treatment could encompass various issues but is not specifically tied to the concept of oro-antral communication. Thus, defining oro-antral communication as the hole between the maxillary sinus and the mouth provides a clear understanding of this phenomenon in dentistry.
