CHAPTER XI. 

 DENTAL CYSTS. 



One of the most interesting features in connec- 

 tion with the study of the teeth is the fact that they 

 may be developed in almost any portion of the body. 

 They are found in connection with the sinuses of 

 the head; the temporal bones; the frontal bones; the 

 base of the ear; the space between the angles of the 

 lower jaw; the lumbar region; the testicles and 

 ovaries and near the kidneys. These teeth may 

 exist singly, in pairs or in clusters. 



Dentigenous cysts contain fully developed teeth 

 which closely resemble a molar tooth in all its parts. 

 They are made up of the different structures entering 

 into the formation of teeth which occupy their 

 natural position. 



The most common situation of these dental cysts 

 is the temporal region at the base of the ear. They 

 produce a fistulous opening from which there is a 

 constant discharge of pus with no tendency to heal. 



C. C. Grice, a veterinary surgeon of New York, 

 reports a very interesting case of the development 

 of a tooth at the base of the ear. He says: * u At
