Fig 28. Traumatic
Ulcer

The most common type of oral ulcers
found in infants and young children, traumatic ulcers
(Figure 28), are caused by mechanical, chemical, or
thermal injuries to the oral tissues. Traumatic ulcers
can be located on the peripheral borders of the tongue,
buccal mucosa, lips, or palate and can vary in appearance
depending on the source and intensity of the trauma.[6]
Burns on the palate may occur after
eating foods or drinking liquids that are too hot.
Infants and young children may develop traumatic ulcers
on the palate from sucking a pacifier or their fingers
or thumb. Nervous fingernail scratching of the gingiva
may result in a factitial injury. In most cases, following
removal of the source of the trauma, ulcers heal within
two weeks.

Ulcer
|
Herpetic ulcers (Figure 29) are usually
preceded by tingling. When the ulcers form, they are
usually a small cluster of vesicles, with no halo.
They are generally located on the hard palate, the
border of the lips, or the attached gingival tissue.
Healing typically occurs within 7 to 14 days.[6]

Ulcer

Other ulcers may be due to trauma, abuse,
the herpes simplex virus, systemic deficiencies, and/or
immune defects. They are most often located on nonkeratinized
movable tissue and have a crater surrounded by a red
halo, as in an apthous ulcer (Figure 30), except for
those caused by trauma or abuse. Ulcers can be painful.
Healing usually occurs within 7 to 10 days.
