“…There are a number of theories regarding the pathogenesis of MRONJ, with varying levels of evidence to support the following as contributing factors: osteocyte apoptosis (Roelofs et al, ); osteoclast suppression (Allen & Burr, ); inhibition of blood vessel formation (Santini et al, ); obstruction of the vasculature (Favia, Pilolli, & Maiorano, ); suppression of soft tissue healing (Reid, Bolland, & Grey, ), impaired immunity (Pazianas, ), genetic risk factors (Choi, Lee, Lee, & Kim, ); and infection or inflammation as a result of oral biofilms (Sedghizadeh et al, ). The role of oral health, and in particular dental extractions, has been extensively reported.…”
