ET ?i-E it-5 r I gi E i s s PHOST HODOIN 'I IA Irrmsov HILLYER, D DS It is not many years ago that Prosthetic Dentistry was unknown 'is such. Dentistry wis either Operative -dealing in iinlv with the tre itment 'md filling of teeth-'md Mechlnical -covering restorations of lost parts Text books issued in the last part of the nineteenth century were devoted to Mech inical Den- tistry 'ind dealt with the subject along purely mechfinical lines. Impression methods were crude and consideration of the mouth prior to the taking of in impression was exceedingly limited. Relief of hard maxillary areas was given but little thought and atmospheric pressure retention of edentulous restorations was almost wholly depended upon. The s ereotyped air-chamber was prevalent in such cases Restoration by means of crowns and bridge-work was confined to but few types and little or no consider ition was paid to pulp canal treatment Except in the practice of '1 limited number focal infection --'is we now know it-was either unknown or but little regarded. 'Mummificationi' of pulps, a method by which the pulpal contents were removed and a paste inserted which was intended to so affect the canal contents as to render them inert, was but a poor attempt to co'pe with the infection problem. The final years of the last century showed a marked awakening in every branch of dental practice. Improvements began in both operative and prosthetic departments. The realization of the importance of oral health conditions as related to that of the general system became ever-increasingly apparent.

One of the greatest aids in the art of healing is the X-ray. It has unquestion- Q ably proven itself indispensable. I p I 2 The teeth as factors in focal infection have received considerable attention. E E N 5 That diseased teeth are likely to produce infection elsewhere in the body, is uni- 5 5 E E :I ?AE5 X-RAY DEPARTMENT ggi 5 :Eg versally accepted. The radiogram is the best means at our disposal in detecting 5'-3'-E such diseased teeth. With the increase in popularity of the theory that diseased E E teeth are among the causative factors in the production of disease in remote por- img tions of the bod , came the increased use of X-ra s. As a result, thousands of .3 2-is y y at?- E E X-ray machines are now in the hands of dentists. The manufacturers' great work 5 2 ' in simplifying X-ray machines, has made this condition possible.
