Aim: This was to create a new easy-to-use index for the treatment of MIH.
Methods: An international MIH working group developed a new MIH index as an epidemiological screening procedure for assessing MIH treatment needs (MIH-TNI), and also for the screening and monitoring of individuals by dental practitioners.
Results: The MIH TNI assesses in particular the extent of the destruction of tooth structure in combination with any hypersensitivity occurring in MIH. The MIH-TNI is suggested as a basis for individual dental examinations covering all MIH typical problems or treatment planning. In addition, this index shall be the basis for decision-making in any MIH therapy studies already planned.
Conclusion: After the validation of the MIH TNI it may be possible to create a standardised approach for dental treatment for MIH.
