It may seem strange that operativeprocedures should be listed as a cause ofpyorrhea, but one need not go far in thetreatment of such conditions without Fig. Radiograph showing loss of lower first molarand destruction of process about the secondmolar as a result of malocclusion. learning that such procedures are a mostimportant cause. A perception of theimportance of proper restorations of cari-ous or missing teeth will help many adentist to develop the skill and patienceso essential in such restorations, for hewill see that much more than the mererestoration of a tooth has been committedto him, and that by observing certainphenomena he will be able to conservethe health of the mouth, while by neglect,conditions much more serious than thosehe undertook to remedy may be induced. A it cnl ion has been called to the beauti-ful exhibition of mechanics which naturegives in Hie occlusal planes of the teethand their inter-relations. We have alsoseen that, by ;i faulty restoration of theseplanes, ;i tooth is placed in malocclusion,and inflammation of flic peridental mem-brane is induced. The mechanics of theapproximal surface
