Antioxidant capsules vs Topical aloe vera gel

Maximal mouth opening (interincisal distance) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)
1 finding from 1 review
  • Sudarshan 2012 (topical aloe vera 10 vs antioxidant capsules 10): reported improvement in interincisal distance but no baseline data, so change could not be determined; excluded from meta-analysis.

Pentoxifylline vs multivitamin and mineral supplement

Severity of oral/mucosal burning pain/sensation · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)
1 finding from 1 review
  • Rajendran 2006 concluded the intervention reduced pain, but pain intensity evaluations were inadequately defined and from interview data, making mean scores difficult to interpret.

Pentoxifylline vs Placebo or no active treatment

Burning sensation (VAS 0-100) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

It is very uncertain whether pentoxifylline changes burning sensation (VAS 0-100) compared with placebo or no active treatment (very low certainty).

Oxitard (antioxidant) vs Topical aloe vera gel

Difficulty in swallowing (participant-reported proxy) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

Oxitard (antioxidant) led to lower difficulty in swallowing (participant-reported proxy) compared with aloe vera gel; GRADE not reported.

Pentoxifylline vs Spirulina

Maximal mouth opening (interincisal distance) · People of any age with a confirmed diagnosis, by clinical examination and biopsy, of oral submucous fibrosis (OSF)

Pentoxifylline may leads to lower maximal mouth opening (interincisal distance) compared with spirulina (low certainty).
