Introduction

Oral Lichen Planus (OLP/LP)
 A chronic
inflammatory disease that causes bilateral
papules, striations or plaques
 May cause erythema, erosions and blisters
 Found on buccal mucosa, tongue and gingiva
 Female: Male ratio: 1.4:1
 Mainly seen in adults over 40 years.
Etiopathogenesis

Purely T lymphocyte mediated inflammatory response.

T lymphocytes cause destruction of keratinocyte cells.

Reticular lichen planus
Papular lichen planus
Plaque type lichen planus
Erosive lichen planus
Atrophic lichen planus
Bullous lichen planus
Clinical Presentation

Reticular lesions
 Most
common type
 Interlacing white keratotic lines called
Wickham’s striae
 Typically bilaterally on buccal mucosa,
mucobuccal fold and gingiva
 Less common on tongue, palate and lips
 Assymptomatic
Clinical Presentation

Erosive lesions





2nd most common type
Mix of erythematous and
ulcerated areas surrounded
by radiating keratotic striae
Similar appearance to
candidiasis.
Mostly buccal mucosa and
vestibule and tongue
Symptomatic:


Sore mouth sensitive to
heat, cold and spices
Pain and bleeding on
touch
2 Plaque lesions :
Resemble focal
leukoplakias
 Vary from smooth flat
areas to raised
irregular plaques
 Often multifocal
 Dorsum of tongue and
buccal mucosa

INVESTIGATIONS
Clinical examination: for reticular LP with
characteristic appearance of Wickham’s
striae or annular pattern on erythematous
background
 Histological and Direct Immunofluorescent
examinations: for plaque and erosive LP
because they can resemble other mucosal
lesions including malignancy

Treatment of OLP

Goal:




Eliminate exacerbating factors



Repair defective restorations or prosthesis
Remove offending material causing allergy
Diet



Reduce painful symptoms
Resolution of oral mucosal lesions
Reduce risk of oral squamous cell carcinoma
Eliminate smoking and alcohol consumption
Eat fresh fruit and vegetables
Reduce Stress
Treatment of OLP

Medication
 Topical
corticosteroids
0.05% clobetasol proprionate gel
 0.1% or 0.05% betamethasone valerate gel
 0.05% fluocinonide gel
 0.05% clobetasol butyrate ointment
 0.1% triamcinolone acetonide ointment

 Can
be applied directly or mixed with Orabase
Treatment of OLP

Medication
 Systemic

Prednisone (for 70kg adult)





1mg/kg/d for 6-8 weeks
Methylprednisolone


10-20mg/day for moderately severe cases
As high as 35 mg/day for severe cases
Should be taken in the morning to avoid insomnia
Should be taken with food to avoid peptic ulceration
Azathioprine – Inhibits synthesis of DNA


Steroid Therapy
to reduce pain and inflammation
Prophylactic use of 0.12% chlorhexidine gluconate may help
reduce fungal infection during corticosteroid therapy
Alternative Treatment of OLP
0.1% topical tacrolimus ointment 2
times/day
 Tacrolimus: immunosuppresive macrolide

 Suppresses
T-cell activation
Intraoral ulceration resolved after 3
months of daily application
 Remission for 1 year without maintenance
