Abstract

This manuscript introduces a new method for teeth numbering system. The primary rationale of lunching this system was to solve previous numbering systems' drawbacks. Furthermore, to keep simplicity and ease of reading and inputting data. The outcome of a questionnaire disseminated among 66 personnel showed the confusion existing among currently used tooth numbering systems. The 'qpdb' system divided the oral cavity into four quadrants, each quadrant represented by alphabetical English letter (q, p, d & b). In spite of being a promising system, this new system lacks the real usage and application, and need more future studies to prove its validity.

Keywords: FDI; Palmer notation system; Teeth numbering system; Universal.
