• Gingiva only 20.6%• Buccal Mucosa only 12.4%

Lichen PlanusClinical Sites (BCD, July 2010)

Desquamative Gingivitis

• Lichen planus• Pemphigus• Pemphigoid• Allergy–Toothpaste –Cinnamon–Preservatives

Lichen Planus• Diagnosis

– Clinical Appearance• Presence of white striae bilaterally on posterior buccal mucosa

– Histopathologic examination• Erosive cases• Isolated lichenoid lesions (in order to rule out premalignancy or

malignancy– Immunofluorescence

• In order to rule out Pemphigus and Pemphigoid, lupus erythematosus and chronic ulcerative stomatitis

Lichen Planus• Treatment–Only for symptomatic patients• Topical corticosteroids • Systemic corticosteroids• Retinoids• Cyclosporine• Tacrolimus and Pimecrolimus

–Patients should be evaluated at least once a year

(Lodi et al 2005) (Al-Hashimi et al 2007)

Lichen Planus• High Potency Topical Corticosteroid

Rx: Fluocinonide gel 0.05% (Lidex)Disp: 15gm tubeSig: Apply to affected area 4x/day. Do not eat or drink for 45 minutes after application

• Highest Potency Topical Corticosteroid Rx Clobetasol 0.05% gel (Temovate)Disp: 15 gram tubeSig: Dry the area and apply a small amount 3-4x/day. Do not eat or drink for 45 minutes after application.

• Widespread gingival involvement:– “suck-down” tray filled with gel and used 2x/day for 15-20

min

• Systemic CorticosteroidRx Prednisone 10 mg tabletDisp: 40 tabsSig: Two tabs bid x 7 days, then 1 tab bid X 4 days, the 1 tab daily until gone

Lichen Planus

Lichen Planus

• Side-effects of topical corticosteroid therapy:–Candidiasis

Lichen Planus

• Combined Topical Therapy–Topical corticosteroid

+Clotrimazole 10 mg Troche 1-3xs daily

orNystatin Oral Suspension 1 tsp 2xs daily

• Pre-malignant potential??– Controversial issue– Clinical studies and case reports suggest that OLP

patients are at a greater risk of developing OSCC• Great variation in source of data, inclusion criteria, length of

follow-up and design– Lichenoid dysplasia vs. lichen planus– Large independent controlled retrospective studies have

shown a significant risk• 1% over a 5 year period

– A minimum of one follow-up visit per year is recommended

Lichen Planus

(Markopoilos et al 1997) ( Lo Muzio et al 1998 ) (Fang et al 2009) (Gandolfo et al 2004) (van der Meij et al 1999)(Al-Hashimi et al 2007)

Be suspicious of a lesion that looks like lichen planus but is localized to the lateral border of the tongue

agEarly dysplastic changes, when the epithelium starts to become atypical or dysplastic but is not invasive yet, can evoke a lichenoid reponse of the body’s immune system

Lichenoid Reactions

• Most common lichenoid reactions:–Non-steroidal anti-inflammatory drugs

(NSAIDs)–Antihypertensives–Cinnamic aldehyde flavoring –Mercury

(Miller et al 1992) (Allen & Blozis 1988) (Issa et al 2005) (Moller 2002)

Lichenoid Reactions

• NSAIDs 19• Cardiovascular drugs 10• Mercury (amalgams) 10• Cinnamic aldehyde 9• Antidiabetics 9• Anti-lipemic 4• Gold salts 2

– Newborns’ immature immune system

– Advanced malignancy– Xerostomia– Immunocompromised

states• HIV/AIDS• Transplant patients

Candidiasis• Pseudomembranous candidiasis– “Thrush”–White material that can be wiped off– Erythematous mucosa underneath– Burning sensation–Metallic taste

Candidiasis

• Erythematous “acute atrophic” candidiasis– Often associated with antibiotics

• Very common: 20%– Affects children and young adults more frequently

• Unknown etiology– The cause appears to be “different things in

different people”

• Immune mediated, self-limiting ulceration– CD8 T-cells produce cytokines which lyse

epithelial cells

Diagnosis of Xerostomia

• A positive response to any of the following questions has been associated with reduced saliva:– Does the amount of saliva in your mouth seem to be

too little?– Does your mouth feel dry when eating a meal?– Do you sip liquids to aid in swallowing dry food?– Do you have difficulty swallowing?

(Plemons et al 2014)

Clinical Signs and Symptoms of Xerostomia

incisal)– Enamel demineralization (chalky spots at the cervical

regions of the teeth)– Increased plaque accumulation– Enamel erosion and attrition– Increased tooth hypersensitivity


• Oral mucosa:– Mucositis– Mucosal desquamation– Atrophic mucosa– Allergic or contact stomatitis and lichenoid lesions

(mostly opposing metal restoration)– Recurrent oral candidiasis– Traumatic ulcerations on the lateral border of the

tongue and buccal mucosa– Painful or burning mouth




• Tongue– Dryness, fissuring, lobulation– Atrophy– Erythema– Loss of papillae– Crenations on tongue (scalloped borders)


• Lips– Dryness, chapping– Peeling– Fissuring– Angular cheilitis

along gingival margins• Other– Dry eye accompanied by dry mouth (Sjogren syndrome)

consumption–Maintaining adequate hydration

gland enlargement should be evaluated for Sjogren’s syndrome– 16-fold increased risk of developing lymphoma
