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]
Cysts of the jaws are cysts—pathological epithelial-lined cavities filled with fluid or soft material—occurring on the bones of the jaws, the mandible and maxilla.Those are the bones with the highest prevalence of cysts in the human body, due to the abundant amount of epithelial remnants that can be left in the bones of the jaws.
For example, the drape of the upper lip can mask the maxillary deficiency to such an extent that it presents as a normal soft tissue profile (REF). Para-nasal hollowing is a key indicator of underlying maxillary deficiency. It is most common in class III patients, but can also present in some class II cases, with bilateral maxillary retrusion.

Typically, clinical signs and symptoms present with bony expansion, or infection. However, bony expansion is uncommon as odontogenic keratocysts grow due to increased epithelial turnover rather than osmotic pressure. When symptoms are present they usually take the form of pain, swelling and discharge due to secondary infection.
The scientific definition of hyperdontia is "any tooth or odontogenic structure that is formed from tooth germ in excess of usual number for any given region of the dental arch." [2] The additional teeth, which may be few or many, can occur on any place in the dental arch. Their arrangement may be symmetrical or non-symmetrical.
The sores may last anywhere from 3–10 days and are very infectious. Some people have recurrences either in the same location or at a nearby site. Unless the individual has an impaired immune system , e.g., owing to HIV or cancer -related immune suppression, [ 22 ] recurrent infections tend to be mild in nature and may be brought on by stress ...
Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone. [11] The mass is generally smooth although in some cases a sharp, bony prominence may be present resulting in tenderness beneath the mucosa. [ 12 ]
Sialolithiasis (also termed salivary calculi, [1] or salivary stones) [1] is a crystallopathy where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct"). Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop ...
