Dr. G. R. Thomas, of Detroit, in the current number of the Dental Cosmos, states that this operation of "replanting" has become so common with him, and the results so uniformly satisfactory, that he does not hesitate to perform it on any tooth in the mouth, if the case demands it; and he finds the cases that demand it, and the number that he operates upon, continually multiplying. He makes it a point to examine the end of the roots of nearly all his cases of abscessed teeth; and a record of more than 150 cases, with but one loss (and that in the mouth of a man so timid that he utterly refused to bear the pain which nearly always follows for a few minutes, therefore necessitating re-extraction), convinces him that the operation is not only practical, but decidedly beneficial to both patient and operator. For one sitting is all that he has ever really found necessary to the full and complete restoration of the case. In the present article, however, Dr. Thomas states that it is his object not so much to speak of replanting as of transplanting, which he has reason to believe is just as practical, so far as the mere re-attachment is concerned, as is replanting. He details, in illustration, a case in which he successfully performed the operation; inserting in the mouth of a gentleman, who had lost a right superior cuspidate, a solid and healthy tooth that he had removed from a lady's mouth four weeks previously. He opened into canal and pulp chamber of the tooth, from the apex of the root only; cut the end off one eighth of an inch (it being that much too long), reduced the size somewhat in the center of the root (it being a trifle larger than the root extracted), filled and placed it in position. He states that the occlusion, shape, and color were perfect, so much so that several dentists who saw the case were not able to distinguish the transplanted tooth from the others. The two features in the case that he calls particular attention to are: first, that although the tooth had been in his office four weeks, there is to-day no perceptible change in color; and second, that the re-attachment is as perfect as though it had been transplanted or replanted the same day of extraction. The operation was performed about three months ago. Dr. Thomas knows of but two obstacles in the way of the perfect practicability of "transplanting:" first, the difficulty of obtaining the proper teeth at the proper time; and second, the possibility of inoculation. The latter is the more formidable of the two, and, to escape the ills that might follow, the greatest caution is necessary. The first difficulty is more easily gotten over, for it is not necessary that the tooth transplanted should correspond exactly in shape and size to the one extracted; if it is too large, it may be carefully reduced; or if too small, new osseous deposit will supply the deficiency. Neither is it necessary, as we have seen, that the transplanted tooth should be a freshly extracted one. As a demonstration of what modern dental surgery is capable of performing Dr. Thomas' statements are very interesting; it is doubtful, however, whether popular prejudice will allow this practice of "transplanting" to become of much use.
