We treated a case of eruption sequestrum in an 8-year 1-month old boy. The patient first came to our clinic with a chief complaint of discomfort in the mandibular. The literature relating to so-called eruption sequestra is reviewed. Two cases in which there were calcified fragments adjacent to the crowns of all four first. Eruption Sequestrum is an unusual disturbance, which consists of fragments of calcified mass overlying the crown of erupting permanent mandibular molar teeth .

ES is usually observed at the time of eruption of the mandibular first molars, but it has been noted occurring with maxillary first molars and mandibular second molars 1,2. The aim of this paper is to report a case of unilateral ES in a 7-year-old Brazilian boy and to describe its histopathological findings. Thus further investigations should be performed to elucidate its microscopic aspects.

The extracted fragment was preserved in formalin for 72 h and submitted to histological processing for microscopic analysis. A rruption amount of existing spongy bone consisted of acute inflammatory cells infiltrate neutrophils.

The histological diagnosis was ES Fig. This page was last edited on 27 Octoberat Services on Demand Journal. The pathological process is as follows:. The microscopic analysis showed non-viable bone tissue of large trabeculae with empty lacunae, evidenced by lack of osteocytes in the lacunae.

After completion of the treatment, follow-up visits were scheduled every 6 months for monitoring dental plaque control as well as for clinical and radiographic assessment Fig. Bone fractures Gross pathology. From Wikipedia, the free encyclopedia. If seen radiographically before tooth eruption, its intraoral appearance may be predicted 1. The sequestra are surrounded by sclerotic bone which is relatively avascular without a blood supply.

In the same case, histopathological examination showed non-vital bone, as reported elsewhere 1,2,5. Eruption sequestrae – three case reviews.

Signs of necrosis were observed on the periphery. Although previously thought to have little clinical significance 1ES may retain biofilm accumulation and lead to pericoronitis, localized swelling, discomfort during mastication, and demineralization or dental caries if it remains for a prolonged time 2.

The treatment plan eruptikn surgical removal of this fragment. This major occurrence in mandibular first molars can be due to these teeth with an ectopic path of eruption, with the mesial cusps at some stage lying mesial to the distal root of the second primary molar 3.

Spongy osseous tissue with an inflammatory cell infiltrate and empty lacuna-like spaces were also identified, in accordance to similar preliminary findings 7. ES may also be retained by tissue covering the distal marginal ridge of an erupting tooth 2.

Signs of necrosis were found on the periphery. Although ES has been reported as a fragment consisting of compact, non-viable bone 1,2,5Watkins 3 described a case composed of dentin and covered in areas by fragments of bacteria-infected cementum.
