Lectures on operative dental surgery and therapeutics . ts of soft wood, shaped in such amanner that when fixed in the vice, and the jaws arefirmly closed (see Fig. 33), a generally diffused or evenpressure may be obtained over the whole surface of thetooth, and the membrane of the root protected againstaccident. The roots should then be cleansed of all extraneousmatter, and filled with oxy-chloride of zinc, after which the 115 tooth may be removed from the vice, and where de-nudation has taken place, the root excised. Then, witha flexible drill, the canal should be formed as nearly aspossible through the centre, following more or less thedirection of the nerve canal. The tube then to beintroduced into the canal, and the cap carefully adjustedto the apex, so that no projecting surface be per-ceptible, otherwise there will ensue irritation of the peri-osteum of the socket, and consequent inflammation, leading to ejection of the tooth. Other complications of astill more dangerous character may arise from this causeof neglect, as trismus. / cl. Fig. 33. Fig. 33 shows c the vice holding the tooth a by means of the woodenclamps b.

Previous to this, however, it is necessary to prepare thecavity of the crown for the reception of the gold filling, but this is now too well understood by you for me to enterinto any particulars ; nevertheless, I deem it advisable tomention that great care should be taken not to obstructthe tube while building around it.
