Abstract

This case series highlights four clinical cases which presented at a dental hospital with atypical features of primary eruption failure. These patients demonstrate the heterogeneous nature of cases that can present with features of primary eruption failure. These cases are presented with a view to introducing a new classification system as an alternative to the encompassing term ‘primary failure of eruption’.

Clinical Relevance: The aetiology of primary eruption failure is poorly understood and can present the clinician with a diagnostic challenge, being based mainly on a diagnosis of exclusion. This case series presents four cases of primary eruption failure that do not conform to the classical clinical description. A new classification system is proposed that groups cases with common clinical features and may aid diagnosis and management.

Tooth eruption is defined as a process whereby the forming tooth migrates from its intra-osseous location in the jaw to its functional position within the oral cavity.1 A tooth may have undergone successful growth and calcification, however, if it fails to erupt it is functionless. There are many theories of eruption as tooth eruption is a complex process which relies on poorly understood timed interactions between cells of the dental follicle and the surrounding alveolus.2 The different theories of tooth eruption include:1

Although many theories of eruption exist, there is little evidence to support these theories and the eruption process is still an intriguing process which requires further research.

Disturbances in tooth eruption have a multifactorial aetiology, including failure as a result of a mechanical obstruction, syndromes, pathology or disruption of the eruptive mechanism. There are a number of syndromes that demonstrate eruption failure as part of their clinical presentation. There is therefore a clear, known genetic origin to eruption failure related to a small number of syndromes including:
