On extraction, with notes on the anatomy and physiology, of the teeth, for medical students . Fig. 2 2. Upper Incisor, with Acute AlveolarAbscess. The pus has raised theperiosteum from the hard palate.(After Dr. Black.) relaxed, with a consequent dilatation of the blood-flow becomes slow and increased in quantity,and the strange phenomenon takes place of the separa- DENTAL PULP AND PERIOSTEUM 39 lion of the white corpuscles from th(; red. The redcorpuscles appear to congregate in the middle; of thestream, while the white corpuscles become slower andslower in their movement, then ultimately stop, andby their amoeboid movement pass through the walls o(the vessel into the surrounding tissue. This exudation, as it increases, produces more andmore pressure on the nerve fibrils, and, being confined. Fig. 23, Upper Molar, with Acute Abscess at theBuccal Roots and Chronic Abscess atthe Palatal Root. (After Dr. Black.) Fig. 24. Alveolar Abscess at the Root of anUpper Molar, discharging into theantrum. (After Dr. Black.) within a hard structure, the pain produced is of athrobbing nature synchronous with each beat of theheart, which is accelerated when the sufferer is in arecumbent position and warm, as when in bed. This is true toothache, or pulpitis. It is easily recog-nised by the throbbing pain, which is relieved by theapplication of cold and increased by warmth. This inflammatory action ends in the death of the 4° DENTAL PULP AND PERIOSTEUM pulp by strangulation, and is followed by its decom-position, with the formation of pus and gases. Then, by continuity of structure, an inflammatoryaction is set up in the periosteal membrane. Preciselythe same phenomenon takes place here : a thickeningof the membrane occurs, due to the exudation, whichactually raises the tooth in its socket.
