# Occlusal Dysesthesia (Phantom Bite Syndrome): A Scoping Review

## TL;DR

This review explores phantom bite syndrome, a condition where people feel a wrong bite without physical cause, highlighting its complex nature and need for better research.

## Contribution

The study provides a comprehensive synthesis of OD's characteristics and management, emphasizing the need for high-quality research.

## Key findings

- OD mainly affects middle-aged women with long symptom durations and psychiatric comorbidities.
- Conservative multidisciplinary management is recommended, avoiding irreversible dental interventions.
- Current evidence is low-quality, mostly from case reports and series.

## Abstract

Background: Occlusal dysesthesia (OD), also known as phantom bite syndrome, is characterized by the subjective sensation of an uncomfortable or “wrong” bite despite the absence of objective occlusal pathology. This scoping review aimed to synthesize the current evidence on the epidemiology, etiology, clinical presentation, diagnosis, and management of OD. Methods: The PubMed, Google Scholar, Scopus, Web of Science, ScienceDirect, and Cochrane Library databases were systematically searched using the terms “phantom bite,” “occlusal dysesthesia,” “occlusal hyperawareness,” “occlusal hypervigilance,” “uncomfortable occlusion,” and “oral cenestopathy.” Studies were screened according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria (2020), and evidence quality was assessed using the Oxford Center for Evidence-Based Medicine levels of evidence. Results: A total of 20 studies were included. OD predominantly affected middle-aged women, with symptom durations often exceeding several years, and was believed to be caused by disorderly central sensory processing or maladaptive signal processing rather than by a primary occlusal abnormality, with high rates of psychiatric comorbidities reported. Current evidence supports conservative multidisciplinary management, including patient education, cognitive behavioral therapy, and supportive pharmacotherapy, and irreversible dental interventions are contraindicated. Conclusions: OD is a complex biopsychosocial condition requiring multidisciplinary care. The current low-quality evidence is primarily obtained from case reports and case series. Therefore, high-quality controlled trials are urgently required to establish evidence-based diagnostic criteria and treatment protocols.
