Idiopathic multiple unerupted permanent teeth: A rare case report

Oral medicine

A disturbed eruption process creates a clinical situation that is challenging to diagnose and treat.

The clinical spectrum of tooth eruption disorders includes both syndromic and nonsyndromic problems ranging from delayed eruption to a complete failure of eruption.

Failure of permanent teeth to erupt without obvious etiology is a rare dental anomaly. Various local and systemic factors have been implicated in failure of eruption of multiple permanent teeth.

The present case report discusses the clinical and radiographic details of a 21-year-old asymptomatic and nonsyndromic patient with multiple unerupted permanent teeth.

Introduction : Tooth eruption has been defined as the movement of a tooth in an axial and occlusal direction from its developmental position within the jaw to its final functional position in the occlusal plane.

The eruption pattern of deciduous and permanent teeth is usually comprehensive and takes place at different chronological age levels. A significant deviation in eruption of tooth, premature eruption and delayed tooth eruption are commonly noted in a clinical practice.

Possible etiologies for failure of eruption of teeth fall into two broad categories: systemic and local factors. Some of the systemic conditions that can lead to delayed or failed eruption are genetic disorders such as cleidocranial dysplasia, Gardner syndrome and osteopetrosis.
