HOW TO TELL THE AGE. 



If there is any enlargement of either jaw, more especially of the 

 upper one, with perhaps a running sore offensive to the smell ; and 

 if in addition there is offensive matter running from the nostril on 

 that side, the trouble may be suspected as arising from a carious 

 tooth, and the jaw on that side must be carefully examined.

It may be asked, How is it, if the trouble arises from a carious 

 tooth, that the matter comes from the nostrils .? 



Answer : By the imprisoned matter forming a sinus into the 

 nasal cavity. 



The treatment for all such cases is, first, in the removing of the 



offending cause, namely, the tooth it- 

 self, and also, as far as possible, the 

 dead or diseased parts, and favoring 

 a healthy condition of growth by 

 cleansing out the parts with a strong 

 solution of carbolic acid or chloride 

 of lime, or any good disinfectant. 

 Next, protect the parts from the lodg- 

 ment of particles of food, by filling 

 with a pledget of tow saturated with the tincture of myrrh, or any 

 good healing astringent, and dress once a day. If there is diseased 

 bone or fungus growth, it should be treated the same as for other 

 difficulties of the same kind.* 



* Since writing the above, my attention has been called to an article in the Journal of Com- 

 parative Medicine and Sur(/ery, of April, 1883, by Dr. Robert Jennings, of Detroit, Mich., in 

 which he refers to a large number of cases of this description.
