Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate. Extension of the lesion to the mucosa of the residual ridges have also been observed. 11% to 13.9% of patients who wear maxillary complete dentures with complete palatal coverage has been reported to have IPH.

Site – gingiva, buccal mucosa, alveolar mucosa, hard palate, floor of the mouth, larynx, oesophagus, penis, vagina, scrotum. Clinical presentation: It is a slow growing, diffuse, exophytic lesion usually covered by leukoplakic patches. Invasive lesions quickly invade bones.
Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause nasal regurgitation during feeding. Following surgery, there may remain a residual orinasal opening on the palate, alveolar ridge, or vestibule of the larynx. A palatal obturator may be used to ...
Acinic cell carcinoma is a malignant tumor representing 2% of all salivary tumors. 90% of the time found in the parotid gland, 10% intraorally on buccal mucosa or palate. The disease presents as a slow growing mass, associated with pain or tenderness in 50% of the cases. Often appears pseudoencapsulated.
Oral cancer affects the areas of the mouth, including the inner lip, tongue, floor of the mouth, gums, and hard palate. Cancers of the mouth are strongly associated with tobacco use, especially the use of chewing tobacco or dipping tobacco, as well as heavy alcohol use.
The chance of cancer formation depends on the type, with between 3–15% of localized leukoplakia and 70–100% of proliferative leukoplakia developing into squamous cell carcinoma. [ 4 ] Leukoplakia is a descriptive term that should only be applied after other possible causes are ruled out . [ 6 ]
It is most commonly found in the palate. [2] The name of the tumor derives from the fact that: It has a varied microscopic architectural appearance, i.e. it is polymorphous. It is non-aggressive when compared to other oral cavity tumors, i.e. it is a low-grade tumor. [1] It forms glands, i.e. it is an adenocarcinoma.
The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
