Physical Injuries
Dr.zameer pasha
• Injuries : harm or damage
• classification of physical injuries
Chronic Cheek Chewing
• Chronic nibbling produces lesions that are
white, shredded
• affects labial mucosa
• affects lateral border of tongue
• No treatment required
Traumatic Ulcerations
• Surface ulcerations occur as a result of acute or chronic irritation or
trauma
• Occurs most often on tongue, lips, buccal mucosa.
• Areas of erythema (red halo) that surrounds central yellow
pseudomembrane (ulcer) or focal red ulcerated area without fibrin
covering; smaller, uncomplicated lesions heal within days
• Complicated ones need local anesthetics, antibiotics and analgesics
Thermal Burns
• Caused by hot foods or
beverages
• Zones of erythema and
ulceration, on palate or
posterior buccal mucosa
• No treatment required
Electrical Burns
• Contact burns
• Electrical arc flows between electrical source and
mouth; saliva is conductor
• Most occur in young children, involve lips and
commissure
• Initial appearance is painless, charred yellow area
with little bleeding; edema develops, then sloughing
• Tetanus shot required
• Primary problem is contracture of mouth opening
during healing (microstomia, prevents eating and
hygiene)
Noninfectious Oral Complications of
Antineoplastic Therapy
• Mouth is common site for complications related to cancer therapy
• Mucositis - areas of ulceration; pain, burning, and discomfort
• Dermatitis - varies according to intensity of therapy
• Intraoral hemorrhage, oral petechiae and ecchymosis
• Xerostomia
Noninfectious Oral Complications of
Antineoplastic Therapy
• When portion of salivary glands included in fields of radiation, remaining
glands undergo hyperplasia to compensate.
• When all salivary glands involved, loss of saliva is progressive, persistent,
and irreversible
• Xerostomia-related caries - diminished saliva leads to decrease of
bactericidal action and self-cleaning properties
• Hypogeusia - loss of all 4 tastes (sense returns for most patients)
• Some may have dysgeusia (altered sense of taste)
Osteoradionecrosis
• Result of non-healing, dead bone
• Dead bone separates from residual vital areas
• Postradiation dental extractions are known risk
