Dental cosmos . It was easily extracted upon first removing the buccal plate of the process afterfinding that there was something abnormal connected with the roots. The patientcould remember no uneasiness attributable tothe tooth, in which, many years ago, two smallamalgam crown fillings had been placed, andwhich are yet perfect. Fig. 2 represents thepalatal aspect of the anomaly, and in bothfigures it will be noticed that the teeth are com-pletely formed and that the crown of the thirdmolar is unusually large. The illustrations imperfectly show the over-flow of the cemental substance on the buccalroots of both teeth (Fig. 1), and the buccal and palatal roots of the third molar(Fig. 2). The fact is indicative of a wide the dento-plastic irritationinduced by contact with the second molar in the efforts of the misplaced third molarto reach its proper place after its normally formative processes had been finished. The union of the several roots at the points of impingement is as complete as. 408 THE DENTAL COSMOS. if the junction had been congenital; yet the buccal and the palatal roots of thesecond rnolar were at their bifurcations separated from each other and from thethird molar by thin septa of the alveolar process. The integrity of the severalpulps and their branches seems in no wise to have been affected, neither was thethird molar crown in any way impaired by its long submergence, but every oneof its eight tuberances and their lines of blending are as perfect as when firstformed.—Will S. Payson, , Castine, Me. In capping pulps I employ an instrument having a cup-shaped end, likethat illustrated in the accompanying figure, for use as follows: With a hollowpunch, cut from thin tin foil a disk somewhat larger than the cup ; lay the disk on a piece of soft rubber ; place the mouthof the cup over the disk, press lightly on it,and its border will fold around the edge ofthe cup so that the tin cap thus formed willremain on the instrument.
