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 .

Informed written consent was obtained from the patient’s mother and this report was approved by the institutional Ethics Committee Protocol Spongy osseous tissue with an inflammatory cell infiltrate and empty lacuna-like spaces were also identified, in accordance to similar preliminary findings 7.
ES is an uncommon clinical finding. From Wikipedia, the free encyclopedia. Views Read Edit View history. Br Dent J ; Please help improve this article by adding citations to reliable sources.
The position of this spicule overlies directly the central occlusal fossa, but within the soft tissue 3. In addition, Maki et al.
Eruption sequestrum – case report and histopathological findings
A biopsy of the area was excised under local anesthesia. This paper reports a case of unilateral eruption sequestrum in a 7-year-old Brazilian boy and describes its histopathological findings.
The sequestra are surrounded by sclerotic bone which is relatively avascular without a blood supply. Within the bone itself, the dequestrum canals become blocked with scar tissue, and the bone becomes surrounded by thickened periosteum.
Eruption sequestrum | definition of eruption sequestrum by Medical dictionary
ES consists of a small irregular bone spicule, but it can also correspond to the eruptiion anatomy of teeth 2. The pathological sequestdum is as follows:. In an unusual case of ES, the specimen consisted of a small irregular calcified mass, composed of dentin and covered in areas by fragments of bacteria-infected cementum 3. The extracted fragment was preserved in formalin for 72 h eduption submitted to histological processing for microscopic analysis.
The histological diagnosis was ES Fig. No significant medical condition was reported. Received May 22, Accepted November 8, All the contents of this journal, except where otherwise noted, is licensed under a Creative Commons Attribution License. A white small fragment, 0. At the 1-week postoperative appointment, the patient was evaluated clinically, although no significant signs and symptoms were revealed.
Na periferia, sinais de necrose foram evidenciados.
This page was last edited on 27 Octoberat Thus further investigations sequfstrum be performed to elucidate its microscopic aspects. The treatment plan included surgical removal of this fragment.
As its early recognition is erjption for preventing a future inadequate surgical intervention, the fragment was removed surgically in this patient, as in other cases 2. 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.
At the same time as this, new bone is forming known as involucrum.
Eruption sequestrum–case report and histopathological findings.
How to cite this article. ES may also be retained by tissue covering the distal marginal ridge of an erupting tooth 2. The microscopic analysis showed non-viable bone tissue of large trabeculae with empty lacunae, evidenced by lack of osteocytes in the lacunae.
An unusual eruption sequestrum. ES is a mass coronally of the erupting tooth with broader borders 3.
Intraoral examination revealed a small white fragment, approximately 0. Eruption sequestrum is an uncommon disturbance in eruption and consists of small fragments of calcified tissue overlying the crowns of erupting permanent molar teeth, especially at the time of eruption of the mandibular first molars.
Due eeruption the avascular nature of this bone, antibiotics which travel to sites of infection via the bloodstream poorly penetrate these tissues, hence the difficulty in treating chronic osteomyelitis. The so-called eruption sequestrum.
Signs of necrosis were observed on the periphery. It is a complication sequela of osteomyelitis. 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.
