Mucocutaneous disorders:
1) Lichen planus
2) Pemphigoid
3) Pemphigus vulgaris
4) Erythema multiforme
5) Lupus erythematosus
Dental restorative materials as
1)mercury, nickel, acrylic.
2) Toothpastes
3) Month rinses
4) Food
6. Traumatic lesions (iatrogenic, accidental)
Chemical injury ( aspirin burn)
Physical Injury
Malocclusion, removable partial
dentures/retainers, and oral piercings;
improper flossing; toothbrush trauma are
common causes of physical injury to the
oral tissues.
Thermal Injury
The most common cause of thermal injury
to the oral region is hot foods/liquids such
as pizza, coffee or soup.
7- Foreign-Body Reactions
Common examples are the introduction of amalgam into the gingiva
during the placement of a restoration, the extraction of a tooth, or an
endodontic apicoectomy with retrofill leaving an amalgam tattoo.
