The dentist's office of the 1930s was quite different from that at the turn of the century. Like the doctor's office of the 1930s, the choice of color was quite important. Shades of yellows were used on the walls and moldings because of its calming and cheerful effects. Dental equipment had also advanced since the turn of the century. The dental chair in this office, made by the S. S. White Dental Manufacturing Company, is hydraulic. The dental unit (produced by the Ritter Dental Manufacturing Company), which combined many elements in a single piece of equipment-drill, lamp, and cuspidor-marked a great step forward in efficiency. The X-ray machine was also found in just about every dental office since the 1920s. The X-ray machine seen here, patented in 1921 and 1925, was made by the Ritter Company of Rochester, New York and was the newest in design. Also of note is the dentist's stool. In earlier days dentists stood while working, but in the 1930s dentists sat, as did the dental hygienist. While this dental office seems somewhat remote and rudimentary compared to the modern dental offices of today, it was at the cutting edge for its time.
