Establishing a new staging system for oral submucous fibrosis and correlation of the proposed staging system to traditional histopathological grading: A clinico-histopathological study

ConclusionWith the data obtained from our study, the following clinical staging pattern can be adapted: stage I indicates that the PRMO is <30%, stage II 30–40%, and stage III>45%. Hence it may be appropriate to asses the disease severity and stage by assessing the degree of disability (i.e., mouth opening reduction considering the individual normal mouth opening ability). The determination of PRMO may be a useful tool in this direction.
