Pruebas Térmicas de Sensibilidad Pulpar en Dientes Permanentes con Pulpitis: Valor Diagnóstico y Limitaciones

Abstract

Introduction: The diagnostic process in endodontics begins with the recognition of the symptoms, the dental history and the objective clinical evaluation, where thermal pulp sensitivity tests are essential in the clinical routine to have an approximation of the pulp condition. However, understanding the nature of the diagnostic tests, and the pulp pathophysiology, are essential to correctly interpret their results. Objective: To recognize the diagnostic value and limitations of thermal pulp sensitivity tests during the endodontic evaluation of the permanent tooth affected with pulpitis. Materials and Methods: The development of this narrative review was carried out through a search strategy in the electronic database, consultation in specialized web portals, and, in addition, required a search for valuable primary articles and books. Results: 34 publications were selected for their contribution and relevance. Conclusions: The sensitivity test using the cold stimulus appropriately results in a high correspondence to rule out a vital or necrotic pulp. This high correspondence is also maintained for reversible pulpitis, with a slight decrease for cases of irreversible pulpitis, although it continues to have a high diagnostic value. However, their main drawbacks continue to be that they are based on a qualitative response from the patient, loaded with subjectivity, and necessarily require experience and skill on the part of the clinician for their execution and interpretation.
