The full classification system based on this formula are displayed in the table below:

It is important to note that historically, there has been professional debate regarding the taurodont classification systems as to: 1) how much displacement and/or morphologic change constitutes taurodontism, 2) whether classification should be indexed stepwise or on a continuum, and 3) whether to include certain teeth in the occurrence of taurodontism. For example, as premolars are narrow mesio-distally, taurodontism is hard to identify radiographically on premolars. Therefore, some researchers exclude premolars from their classification systems. Additionally, there has been criticism over the use of landmarks that undergo changes. For example, due to trauma or wear, tertiary dentin can be deposited which can then alter some measurements; thus, caution should be employed when diagnosing taurodontism in this case. Finally, as these measurements are dimensionally quite small, they are also subject to large relative error. Clinical Considerations
The altered morphology of taurodont teeth can present challenges during dental treatment. Most notably, endodontists will have difficulty in not only removing the voluminous pulp, but also filling the large pulp chamber and complex root canal system. Prosthodontists and orthodontists should also exercise caution in using taurodont teeth as sites for dental anchorage. Due to the apical displacement of the furcation area, the taurodont tooth is not held as securely in the alveolar socket. Conversely, this may make taurodont teeth easier to extract. Finally, taurodont teeth may have favorable prognosis from a periodontal point of view, as the furcation area is apical and thus less susceptible to periodontal damage.
Refractory cytopenia with multilineage dysplasia is a form of myelodysplastic syndrome.It is abbreviated "RCMD". References
