Abstract

OBJECTIVES:

Idiopathic bone cavity (IBC), also named simple or traumatic bone cyst, is a common lesion of unknown cause. The mandible is a very common location, although it may occur in any bone of the body. The authors performed a retrospective analysis of 44 cases in order to assess the causation of this entity.

METHODS:

Each case was analysed by two of the authors (IV and SM) for medical and dental history, history of mandibular/maxillary trauma, clinical presentation, radiographic appearance, surgical findings and histopathology.

RESULTS:

This retrospective study suggested a possible relationship between IBCs and orthodontic treatment. This association was noted in 10/44 cases (22.73%). All of these cases were located in the mandible and were well-circumscribed radiolucencies. Evaluation of these cases disclosed that 6/44 (13.64%) demonstrated scalloping, and 3/44 (6.82%) revealed bony expansion. The age range of the patients evaluated was 9-74 years. None of these cases had a history of trauma or extractions in the area.

CONCLUSIONS:

The findings of this retrospective study suggest an association between orthodontic treatment and the development of this IBC. This occurrence may be multifactorial; further research in the dental science is required.
