Erosive LP symptoms
Episodic pain to severe discomfort
Symptoms may persist weeks or longer
Symptoms result in weight loss, nutritional deficiencies and depression.

Differential Diagnosis for LP
lichenoid dysplasia
contact stomatitis
lichenoid reaction.
Treatment Goals LP
There is no cure, therefore;
Reduce length and severity of symptoms
Resolve oral mucosal lesions
Reduce risk of malignant degeneration to squamous cell carcinoma
Treatment Issues LP
Maintain good oral hygiene because meticulous oral hygiene reduces symptom severity
Oral hygiene is difficult to accomplish during active disease
Treatment options for LP (rx)
Oral anesthetic rinse (1% Dyclonine solution)
Antibiotics
Antifungals (with steroid); nystatin with triamcinolone
Corticosteroids
tx regimens LP
gel better than cream, less soluble
steroid carriers
Need to border mold the
impressions so tray extends
to mucobuccal folds for rx delivery
Intra-lesion steroid injections for LP
12 mg/week dexamethasone for 8 weeks
5 -10 mg/week triamcinolone PRN
systemic roids for LP
antiviral tx for LP
Hydroxychloroquine (Plaquenil)
- relieve inflammation, swelling, stiffness, and joint pain
Thalidomide
Bad history when used in pregnancy for anxiety, morning sickness, headache, etcc. (1950s);
Thalidomide babies had lack of appendage development (arms,
legs). Other aplasias - ears or malformed kidneys.
Contemporary use for inflammatory mucocutaneous diseases
Treatment
