Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
A cyst may become acutely infected, and discharge into the oral cavity via a sinus. Adjacent teeth may be loosened, tilted or even moved bodily. [6] Rarely, roots of teeth are resorbed, depending upon the type of cyst. The inferior alveolar nerve runs through the mandible and supplies sensation to the lower lip and chin.
Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection. Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [ 1 ]
Examples of the most common tissues examined by means of a biopsy include oral and sinus mucosa, bone, soft tissue, skin and lymph nodes. [6] Types of biopsies typically used for diagnosing oral and maxillofacial pathology are: Excisional biopsy: A small lesion is totally excised. This method is preferred if the lesions are approximately 1 cm ...
Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose. The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth.

In addition to periapical abscesses, periapical periodontitis can give rise to various related lesions, including periapical granulomas and cysts. [11] A periapical granuloma (also referred to as an 'apical granuloma' or 'radicular granuloma') is a mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital ...
Classic symptoms of sinus disease such as headache, facial pain, purulent nasal discharge or nasolacrimal obstruction [12] may occur when maxillary sinus is involved. According to a study, 45.7 percent of dentigerous cysts involved mandibular third molar. [8] On the other hand, only 2.7 percent of dentigerous cysts involved the maxillary premolar.
