Besides discussing the osteomyelitis of the jaws, this particular chapter highlights the analysis of classification system as well as analysis of certain older terms regarding osteomyelitis which have been used in the literature. As it is well understood that Zurich system of classification has various advantages as compared to other different classification systems used in the literature, there still exist certain older terms for osteomyelitis which are actually misnomers. These include Condensing Osteitis and Focal sclerosing Osteomyelitis. Further, there are certain other rare types of osteomyelitis in which it is very difficult to trace the actual reason or causative agent. Those kinds of osteomyelitis may have a separate position in the classification system. One such example is tuberculous osteomyelitis in which sometimes it becomes difficult to trace the cause.
