Persistent Idiopathic Dentoalveolar Pain: An Educational Overview for Dental Students

Persistent idiopathic dentoalveolar pain (PIDAP) is a chronic orofacial pain condition characterized by persistent pain in the absence of detectable dental pathology.Due to its ambiguous clinical presentation, PIDAP is frequently overlooked or misdiagnosed, leading to prolonged patient suffering and unnecessary dental treatments.This review provides a structured educational overview of PIDAP for dental students and early-career clinicians, covering its definition, taxonomy, differential diagnosis, pathophysiology, clinical significance, and management principles.A narrative literature review was conducted using PubMed and Scopus databases with the following search terms: "persistent dentoalveolar pain," "atypical odontalgia," "PIDAP," "orofacial pain," and "chronic overlapping pain conditions."The search covered publications up to December 2024, limited to English-language articles.Priority was given to relevant classification guidelines, epidemiological data, and studies addressing diagnostic challenges, nomenclature changes, pathophysiology, and the relationship between PIDAP and chronic overlapping pain conditions (COPCs).Thirty-four key references were included after screening.Current diagnostic criteria, the historical evolution of PIDAP taxonomy, and major pathophysiological hypotheses-including peripheral sensitization, central sensitization, and nociplastic pain mechanisms-are summarized.The high rate of comorbidity with COPCs and the frequent misdiagnosis of PIDAP highlight its clinical importance, as epidemiological data indicate that diagnostic delays may range from several months to years.Improving awareness and understanding of PIDAP among dental students and clinicians can facilitate early recognition, reduce misdiagnosis, and contribute to more effective management.Incorporating PIDAP-related education into undergraduate dental curricula and continuing education programs may further bridge current knowledge gaps and improve patient outcomes.
