2 Cheek chewing Morsicatio buccarum, chronic chewing of cheek, DDx: idiopathic leukoplakia, lichen planus, linea alba, chemical (aspirin) or thermal burn, toothpaste reaction, cheek chewing Description-large ulcerated hyperkeratotic macule, ragged, appears to be pealing off, white and red, may or may not wipe off Common locations- anterior buccal mucosa, labial mucosa, lateral boarder of tongue, along plane of occlusion

3

4 Aspirin burn -habit of placing aspirin on gums, very painful, obtain hx from pt. -D Dx: Chemical burn, cheek chewing, leukoplakia, toothpaste or mouthwash reaction, candidiasis, lichen planus, erythema migrans -Large, white, may or may not be rubbed off, erythematous macule. painful -On gingiva, buccal mucosa

5

6 Peroxide burn caused by pt rinsing with peroxide. (tx for ANUG), obtain hx from pt. D Dx: Chemical burn, cheek chewing, leukoplakia, toothpaste or mouthwash reaction, candidiasis, lichen planus, erythema migrans Large, white, may or may not be rubbed off, erythematous macule. painful Generalized in oral cavity

7

8 Thermal burns Thermal most often caused by pizza, obtain hx from pt. Erythematous macule, may have pseudomembranous covering, may be ulcerated, painful. D Dx: Chemical burn, cheek chewing, leukoplakia, toothpaste or mouthwash reaction, candidiasis, lichen planus, erythema migrans Located on vermillion boarder, tongue, hard palate.

9

10 Cotton roll stomatitis -iatrogenic, sizing (paste) sticks to tissue. Obtain hx from pt. -Tx: Wet cotton before removing. -Sloughing traumatic lesion, erythematous macule, may have pseudomembranous covering, may be ulcerated. -D Dx: Chemical burn, cheek chewing, leukoplakia, toothpaste or mouthwash reaction, candidiasis, lichen planus, erythema migrans

11

12 Riga Fide early erupted tooth, infant w/ ulcer on undersurface of tongue D dx: riga fide, aphthous lesion Age of pt will make dx.

13

14 Toothbrush abrasion horizontal pattern of erosion on attached gingival, erythematous, coalescing ulcers. D Dx: recurrent intraoral herpes simplex, tooth brush abrasion

15

16 Ionizing radiation damage skin damage: telangectasia, hair loss, mucositis, (serous glands), xerostomia (prevention with good oral hygiene is key!) Osteoradionecrosis: Damage to blood vessels, microorganisms can’t be controlled by body’s defenses, bone death results D Dx: burn, ionizing radiation damage, xerostomia due to medications
