ABSTRACT

Most dental consultations are related to intraoral pain disorders affecting dental, periodontal and mucosal structures. Although the originating cause of pain and the anatomical structure frequently co-localise, orofacial pain and particularly oral pain are sometimes referred. That is, pain may be caused by extraoral processes out of the maxillofacial territory. Likely, some intraoral conditions such as an occlusal imbalance may also affect extraoral structures, leading to tension and pain on the neck, head, and back. Orofacial pain research is however an emerging discipline in comparison to other anatomical regions. This may be due, in part, to the fact that oral pain tends to recede over time or after tissue healing –in case there was an injury–. Notwithstanding, half of the patients reporting any sort of orofacial pain suffers chronically. And unlike acute receding pain, chronic pain is no longer a symptom, but a diffi cult-to-manage pathology, with scarce or none relation to the mechanisms that caused it. Moreover, the lack of appropriate anamnesis and clinical examinations, inaccurate pain syndrome nomenclatures or difficulty in diagnosis hamper sometimes an optimal therapeutic approach. Most oral pain classifications are still based on the affected anatomical structure rather than on the nociceptive mechanism itself. On the other hand, the precise aetiology of most of the so-called atypical algiae or the burning mouth syndrome is still unknown. The present review article aims to describe the main reasons for pain consultation at the dental clinic, with particular emphasis on the type of pain from a mechanistically point of view: nociceptive, inflammatory, neuropathic, psychogenic or mixed.



RESUMEN

La mayor parte de las consultas odontológicas están relacionadas con dolores intraorales que afectan a estructuras dentarias, periodontales y mucosas. Aunque generalmente la causa originaria del dolor y la estructura afectada coinciden en la localización, en ocasiones el dolor orofacial y, particularmente, el dolor oral, es referido. Esto es, el dolor puede deberse a procesos de origen extraoral localizados fuera del territorio maxilofacial. De igual manera, determinados trastornos orales, como un desequilibrio oclusivo, pueden afectar también estructuras extraorales, ocasionando tensión y dolor en cuello, cabeza y espalda. La investigación en dolor orofacial es, sin embargo, una disciplina emergente en comparación con otras áreas anatómicas, quizás debido, en parte, a que el dolor tiende a remitir con el tiempo o con la sanación del tejido afectado (si hubiera una lesión). Sin embargo, la mitad de los pacientes con algún tipo de dolor orofacial lo sufre de manera crónica y, a diferencia del dolor agudo, remitente, el dolor crónico no es ya un síntoma, sino una patología de difícil manejo, con escasa o ninguna relación con los mecanismos que lo originaron. Además, la falta de una adecuada anamnesis y exploración clínica, nomenclaturas inapropiadas o la dificultad de diagnóstico, hacen complicado en ocasiones un óptimo abordaje terapéutico. La mayoría de las clasificaciones de dolor oral siguen atendiendo a la estructura anatómica afectada más que al propio mecanismo nociceptivo. Por otra parte, la etiología exacta de muchas algias denominadas atípicas o del síndrome de boca ardiente sigue siendo desconocida. Esta revisión pretende describir los principales motivos de consulta por dolor en la clínica dental, poniendo particular énfasis en el tipo de dolor desde el punto de vista de su mecanismo: nociceptivo, inflamatorio, neuropático, psicogénico o mixto.
