Schematic of maxillary lateral incisors in the human mouth for both permanent and primary teeth. Maxillary lateral incisor agenesis (MLIA) is lack of development of one or both of the maxillary lateral incisor teeth. In normal human dentition, this would be the second tooth on either side from the center of the top row of teeth. The condition ...
The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [ 1 ] [ 2 ] through the semilunar hiatus .
Salivary gland aplasia (also termed salivary gland agenesis) is the congenital absence of salivary glands. Usually the term relates to the absence of some or all of the major salivary glands. It is a rare condition, and most known cases have been in association with syndromes of the ectodermal tissues, [1] particularly the lacrimal apparatus. [2]
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation.Hyposalivation often results in a dry mouth condition called xerostomia, and this can cause tooth decay due to the loss of the protective properties of saliva.
Recent studies have classified two types of maxillary sinus septa: primary and secondary. Primary septa are those initially described by Underwood and that form as a result of the floor of the sinus sinking along with the roots of erupting teeth; these primary septa are thus generally found in the sinus corresponding to the space between teeth, as explained by Underwood.
In anatomy, the Schneiderian membrane is the membranous lining of the maxillary sinus cavity. [1] Microscopically there is a bilaminar membrane with pseudostratified ciliated columnar epithelial cells on the internal (or cavernous) side and periosteum on the osseous side.
The maxillary sinus is known for its thin floor and close proximity to the posterior maxillary (upper) teeth. [ 1 ] [ 6 ] The extraction of a maxillary tooth (typically a maxillary first molar which lies close to the lowest point of antral floor although any premolar or molar can be affected) is the most common cause of an OAC (which can then ...
Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus, which is in close proximity to the upper teeth. [2]
