The incisive papilla is an oval [1] [2] midline mucosal [2] prominence of the anterior hard palate [1] overlying the incisive fossa. [1] [3] [2] It is situated posteriorly to the central incisors, [2] and represents the anterior extremity of the palatine raphe. [1] The incisive papilla marks the position of the foetal nasopalatine canal. [1]
Historically, the cause of nasopalatine duct cysts has been somewhat of an enigma. Although it was originally postulated that the cyst formed from trapped epithelial cells during embryonic fusion of the palatal bones, [3] it is now thought that it forms from oronasal ducts present within the incisive canals.
The cyst needs to be located behind the palatine papilla. [7] The cyst needs to be grossly symmetrical in the palate's midline. [7] A cyst cannot be connected to a non-vital tooth or have any communication with an incisive canal. [7] It should be ovoid or round radiographically. [7]
The origin of the lesion is unclear. This condition appears to be of an inflammatory nature. [7]An excessive denture palatal relief area, creating a void between the denture base and the tissue of the palate, encourages food entrapment and so encouraging bacterial and fungal growth between the two surfaces.
The palatine raphe (also median palatine raphe [1]) is a raphe of the oral cavity. It is a narrow, slight midline ridge extending anteroposteriorly across the palate, from the incisive papilla anteriorly to the palatine uvula posteriorly. [2]
The treatment of a submasseteric space infection is usually by surgical incision and drainage, and the incision is placed intra-orally (inside the mouth) or both intra and extra-orally if other parts of the masticator space are involved.
This larger white, rough, raised lesion needs to be recorded so that changes may be made in the dental treatment plan regarding the patient's parafunctional habits. [10] [11] Even keratinized tissue can undergo further level of hyperkeratinization; an increase in the amount of keratin is produced as a result of chronic physical trauma to the ...
Incisive bone, the portion of maxilla adjacent to the incisors. Incisive foramen or anterior palatine foramen, a funnel-shaped opening in the bone of hard palate immediately behind incisor teeth. Incisive canals or foramina of Stensen. Incisive papilla, projection on the palate near the incisors.
