1. Oral submucous fibrosis (OSF) is a chronic disease characterized by inflammation and fibrosis of the oral cavity that causes mouth opening restriction. It is associated with chewing betel nut and is considered a precancerous condition.
2. OSF has multiple treatment approaches including medication, physiotherapy, surgery, and lifestyle changes. Medications include steroids, hyaluronidase, and pentoxifylline to reduce inflammation. Surgeries such as fibrotomy and grafts help improve mouth opening.
3. While various treatments provide temporary relief, recurrence of fibrosis is common. The disease has no definitive cure, though early diagnosis and lifestyle changes may help prevent progression. Close monitoring is also
3. • Diffuse firm whitish areas of submucosal scarring and
fibrosis usually associated with frequent and prolonged
contact with betel nut quid, tobacco, hot peppers.
• Lesions have a higher than normal risk of developing
squamous cell carcinoma.
5. HISTORY:
Sushruta ( 600 B.C) : described in his book
“ Sushruta Samhita” , a condition affecting the mouth with symptoms
and signs similar to those of OSMF. He labeled this condition as
“VIDARI”
“Schwartz” in 1952 was the first person to bring this condition
again into the lime light. He described this condition under the
heading “ Atropica Idiopathica Mucosa Oris “
“Joshi” ( 1953), who introduced the term “ OSMF of palate
and pillar” first time in India. He was the first who has thrown
light on etiology as well clinical picture of disease.

Lubrication of Inflamed Mucosa
Modification of Local Anesthesia Technique- The
Vazirani-Akinosi closed-mouth mandibular block is
chosen
Modification of Surgical Technique- For extraction of
mandibular third molars using a transalveolar
technique, the flap design must be conservative
without overextension of distal releasing incision.
Tearing or shredding of flap, lingual gingiva,
pterygomandibular raphe must be avoided.

76. • Numerous treatment modalities that have been implicated
• Most stable results was achieved by tongue flap.
• BFP grafting is suitable alternative to tongue flap
• “There are chancesof recurrence in the process of increasing fibrosis. Thus a close follow-up of these
patients should be done”.
• “In well established cases, allavailablemodalities of treatment fail to give lastingrelief. The
expectancy of life is not reduced unless the OSMF is associated with malignancy“ .
• A more extensive clinicaltrials involving a greater number of casesand including more parameters
are necessary
