A CLINICAL STUDY OF ODONTOMES. 
73 
Our prognosis in case of odontomes is almost without ex¬ 
ception, very favorable. No class of surgical operations can 
well offer safer or more satisfactory results if the operation 
be properly performed, the errors we have pointed out obvia¬ 
ted, and the after-treatment properly carried out. 
One point of importance should not be overlooked—the 
operation should always be made on the veterinarian’s 
premises, where all needed instruments and appliances will be 
at hand, as it can never be told just what will be needed until 
the work is done. Then the patient should by all means be 
left in the immediate care of the operator until the wound is 
granulating at every part, as it is next to impossible in many 
cases, to find and remove, at the time of operating, all the de¬ 
tached or diseased fragments, so that they need to be searched 
for daily for three to six days. A reflecting lamp, by throw¬ 
ing a strong light into the affected cavity, will greatly aid in 
detecting these overlooked fragments. 
EXPLANATION OF PLATES. 
Fig 1.—Multilocular cyst, from a two-year-old colt. 
a. Fourth superior molar recently erupted, and 
b. Fifth superior molar, not yet erupted, both showing by wires inserted, open¬ 
ings from table to fang between the layers of central inversion of enamel. 
c. d. e. and /. Cyst walls from the fang of fourth molar. 
Figs. 2, and 3. Second superior pre-molars from two-year-old colts, which had 
small follicular cysts in connection with their fangs. 
Wires passed through the teeth show openings from table to fang between 
central inverted plates of enamel, as in Fig. 1. 
Fig. 5. Cementoma of corner incisor (inferior). 
a. table surface of tooth. 
Fig. 4. Cementoma of third superior molar from four year-old-mare, affected 
two years. 
a. Cementum tumor on inner side of tooth. 
Fig. G. Compound Follicular Odontome (suppurating) . 
a. Antero-posterior view of tooth, showing its beveled condition from unilat¬ 
eral mastication, also the greatly enlarged condition of the fang. 
b. View of the inner side of tooth (wearing surface) showing wire passed be- 
ween the inverted enamel plates, constituting a free communication between 
the abscess and the table surface. 
Fig. 7. Detached pieces of dental tissue from the abscess of Fig. 6. 
a. Irregular masses of enamel and dentine. 
b. Piece of cementum from same.
