NOTES ON 0D0NT0MES. 
By W. L. Williams, Professor of Surgery and Obstetrics, New 
York State Veterinary College. 
Read before the New York State Veterinary Medical Society, September, 1898. 
Literature upon tooth tumors in domesticated animals is 
scant, standard works on surgery and dentistry being well-nigh 
silent, compelling the student to rely almost wholly upon cur¬ 
rent veterinary literature. 
In the latter field J. Bland Sutton * contributes a highly in¬ 
structive article dealing chiefly with the origin and classifica¬ 
tion of these neoplasms, upon which the writer f based a some¬ 
what extended contribution dealing largely with the clinical and 
operative phases of the subject, adding later a brief case report. J 
Other case reports occur here and there throughout our litera¬ 
ture, though largely fragmentary in character. 
Desiring to avoid repetition, we confine ourselves to a few 
notes which though not directly united by logical relationship, 
may yet possess interest to the student and practitioner as related 
to the subject in chief. Phrst, let 11s remark that the horse is 
pre-eminently subject to tooth tumors. 
While odontomes have been recorded by Sutton and others 
in man, goats, bears, and other animals, we do not find them 
nearly so frequent in any other as in the horse. This tendency 
to aberration in the development of horses’ teeth is not confined 
to the production of tooth tumors within the normal alveoli, but 
very frequently evinces itself in the form of supernumerary teeth, 
such as the imperfect supernumerary molars or wolf teeth, and not 
infrequently extra molars of full or exaggerated size situated be¬ 
hind or before, outside or inside the normal molar arcade, or we 
may find a few extra incisors or a complete double set.
