The Problem and Its Background
The profession of speech therapy is little more than twenty-five years old. As in any new field many beliefs are currently held without experimental corroboration. One of these concerns dentition. The claim is made by some speech therapists that missing teeth cause lisps. Other therapists and writers have doubted this belief. It is therefore the purpose of this study to determine the relationship between missing and articulation of the sibilant sounds, [s], [z], [S], , [tS], [d3], among first grade school children.
