Lecluse treated in a succinct but correct manner the anatomy of the mouth; invented some and perfected other instruments, the most important of which is the elevator that still bears his name, and . . . he frequently performed the operation of replantation, warmly recommended by him as an excellent means of cure in certain cases of caries" (Guerini, History of Dentistry, p. 305). "Louis Lecluse . . . was a scintillating personality, whose activity was divided his entire life between dentistry, the theater, and poetry. . . . This book contains an anatomical section, a practical section, and a section devoted to the deciduous teeth. The special oral anatomy . . . is divided, just as our modern textbooks, into osteological, myological, angiological, neurological, and sarcological parts. . . . On the practical side. Lecluse mentions some new tooth removers. . . . Mainly he mentions his own specialized instrument for luxation of the mandibular third molar (he also used it for the maxillary counterparts). This instrument which is adjusted with a bayonet-shaped bending joint is still used today as the 'Lecluse', and numerous modern levers operate on its principle. Point A is applied diagonally between the last two molars, and levers the third molar out when turned with the next-to-last tooth as a fulcrum. . . . The third section . . . concerns itself with generalities . . . with a wide variety of good suggestions for preservation of the primary teeth" (Hoffmann-Axthelm, History of Dentistry, p. 210).
