Stomatitis nicotina is a diffuse white patch on the hard palate, usually caused by tobacco smoking, usually pipe or cigar smoking. [2] It is painless, [ 4 ] and it is caused by a response of the palatal oral mucosa to chronic heat.
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.

Aphthous stomatitis, [2] or recurrent aphthous stomatitis (RAS), commonly referred to as a canker sore or salt blister, is a common condition characterized by the repeated formation of benign and non-contagious mouth ulcers (aphthae) in otherwise healthy individuals.
In addition to sores, blisters and ulcers, stomatitis can cause discoloration of the inner lips, inner cheeks, and tongue, adds Brynna Connor, MD, a family medicine specialist in Austin, TX, and ...
Nicotinic stomatitis is whitening of the hard palate by hyperkeratosis caused by the heat from smoking or from drinking hot liquids. This irritation also causes inflammation of the duct openings of the minor salivary glands of the palate, and they become dilated. This manifests as red patches or spots on a white background. [12]
Migratory stomatitis (or geographic stomatitis) is an atypical presentation of a condition which normally presents on the tongue, termed geographic tongue. Geographic tongue is so named because there are atrophic , erythematous areas of depapillation that migrate over time, giving a map-like appearance.
Hyperkeratinized tissue is also associated with the heat from smoking or hot fluids on the hard palate in the form of nicotinic stomatitis. [10] The lamina propria is a fibrous connective tissue layer that consists of a network of type I and III collagen and elastin fibers in some regions.
To check the uvula, a tongue blade is pressed down on the patient's tongue and the patient is asked to say "ah"; the uvula should look like a pendant in the midline and rise along the soft palate. Abnormal findings include deviation of the uvula from the midline, an asymmetrical rise of the soft palate or uvula and redness of either.
