Classificação Internacional de Dor Orofacial, Primeira Edição (ICOP) - versão Português Brasileiro




Preface of the Brazilian version of the ICOP

It is with great satisfaction and enthusiasm that we present the Portuguese version of the ICOP (International Classification of Orofacial Pain, in English). ICOP is the result of an effort by several world representative entities in the area of Orofacial Pain. That initiative culminated in a comprehensive document that aims to standardize the classification of Orofacial Pain.

Originally published in 2020 by the International Headache Society (IHS), we now have our version in Portuguese, to be applied in research and clinical activities, also providing subsidies to discuss future steps. The ICOP is formatted in such a way that it provides a logical and coherent flow of reasoning for determining the diagnosis.

We must also remember that this document is part of the initiative of the World Health Organization (WHO), through the International Classification of Diseases (ICD), and should be part of the entity's official document from 2022, which makes it even more important as a tool for “conversation” with other health specialties involved in the diagnosis and treatment of pain.

We would like to say a huge thank you to all the members of the Committee involved in the translation process and especially the Brazilian Headache Society (SBCe) for their support for the materialization of this project. We also thank Cephalalgia for allowing the translation of the ICOP originally published by them, and the publication of the Brazilian version.

We also emphasize that this is a “beta” version of the ICOP, which means that it must undergo adjustments and improvements after a period of use. Thus, we invite all of you to use, discuss, apply the criteria and, above all, give your opinion so that we can always take another step forward in the difficult but fundamental task of classifying Orofacial Pain.

Good reading!
