Description
Eruption disturbance indicates abnormal eruption of a tooth due to a specific reason. These disturbances are classified on the basis of abnormal eruption time (retarded eruption), quantity (infraoccluded deciduous teeth, impacted tooth), or direction (ectopic eruption). In pediatric dentistry, the frequency of involvement of maxillary incisors is the highest, followed by maxillary canines. Causes of eruption disturbance consist of general and local factors. Examples of general factors are cleidocranial dysostosis, osteopetrosis, hypothyroidism, rickets, and Down syndrome, and those of local factors are apical periodontitis, supernumerary teeth, odontoma, fused primary maxillary incisors, thickened gingival tissue, cyst, prolonged retention, and dental ankylosis. Eruption disturbance is suspected if eruption or exchange is delayed compared with the identical contralateral tooth. This is also applicable in radiographic examination. Treatment options include removal of the cause, creating space for eruption, fenestration, and traction.
It is important that eruption disturbance is detected at an early stage and treated at the optimal time.
