Transcript of Cheek chewing
Cheek chewingMorsicatio 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
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
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
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.
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
Riga Fide
• early erupted tooth, infant w/ ulcer on undersurface of tongue
• D dx: riga fide, aphthous lesion• Age of pt will make dx.
Toothbrush abrasion
• horizontal pattern of erosion on attached gingival, erythematous, coalescing ulcers.
• D Dx: recurrent intraoral herpes simplex, tooth brush abrasion
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
Acid erosion of enamel
• caused by stomach acid (reflux or bulimia), lemons, tomato juice.
• Teeth concave, cupped out cusps, unusual wear pattern, exposed dentin
• D Dx: acid erosion, attrition
