Modified Triadan-Simplified Tooth Identification in Veterinary Dentistry
All of veterinary dentistry centers on communication. Comprehensive oral care involves excellent Problem Oriented Oral Medical Records; detailed oral exams; precise oral radiology; and thorough identification of all pathology.
The Modified Triadan Numbering System is the key that unlocks a unique nomenclature that allows for an exchange of medical information from............... practitioner to client and....... in referral cases....... to the animal dentist. We live in an age of telemedicine. To communicate in medicine standards must be utilized that are universally accepted.
Over a quarter of a century ago, Michael R. Floyd, DVM, FAVD wrote a paper in The Journal of Veterinary Dentistry: "The Modified Triadan System: Nomenclature for Veterinary Dentistry" [JVetDent 81991]. With Dr. Floyd's permission his paper became an important Appendix to An Atlas of Veterinary Dental Radiology-Edited by Donald H DeForge, VMD-Fellow of the Academy of Veterinary Dentistry and Ben H Colmery III, DVM-Diplomate of the American Veterinary Dental College.
The rest is history. In the MTS, all canine teeth end in "4" and all first molars end in "9"-[the Rule of 4 and 9]. This system applies equally well to all domestic species. As Dr. Floyd wrote: "The Modified Triadan System has a distinct advantage of anatomical notation in that it is equally easy to write, type, speak, print, store, and retrieve. It leaves no room for confusion about left and right; upper and lower; or comparative evaluations between species even when one species has a reduced dentition."
It is the responsibility of every veterinarian and technician to understand and utilize this system in their veterinary hospital or clinic. It is impossible to communicate without a consistent vocabulary. Veterinary dentistry continues to grow. Technology and products change on a weekly basis. To grow, we must never forget the words complete and accurate.
This author thanks Dr. Michael Floyd for his contribution to veterinary dentistry in the arena of nomenclature and exchange of oral information. Comprehensive Oral Diagnostics and Treatment [CODAT] is based on the Modified Triadan System [MTS]. Once you review this simple system of nomenclature, you will see how simple it is to incorporate it into your computer Problem Oriented Oral Medical Records.
