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 .

Thus further investigations should be performed to elucidate its microscopic aspects. As its early recognition is important for preventing a future inadequate surgical intervention, the fragment was removed surgically in this patient, as in other cases 2.

ES is a sequeetrum coronally of the erupting tooth with broader borders 3. Bone and joint disease M80—M94— Views Read Edit View history.
Eruption sequestrum – case report and histopathological findings
Osteitis fibrosa cystica Brown tumor. However, when the fragments are large or the eruption speed is slow, small bone fragments on the occlusal surface remain unresorbed and exposed to the mucosa prior to molar eruption, which forms ES 1.
Signs of necrosis were found on the periphery. An unusual eruption sequestrum. Openings in this involucrum allow debris and eruptiln including pus to pass from the sequestrum via sinus tracts to the skin.

A white small fragment, 0. In addition, Maki et al.
A biopsy of the area was excised under local anesthesia. In the same case, histopathological examination showed non-vital bone, as reported elsewhere 1,2,5.
The sequestra are surrounded by sclerotic bone which is relatively avascular without a blood supply. The microscopic analysis sequeshrum non-viable bone tissue of large trabeculae with empty lacunae, evidenced by lack of osteocytes in the lacunae. 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.
Periapical radiograph did not show adequately this fragment. Received May 22, Accepted November 8, The biopsy tissue was composed of a 0.
There was neither history of oral-facial trauma nor abnormalities upon extraoral examination. How to cite this article.
There was neither history of pain nor evidence of dental caries or abnormality in other soft tissues. The pathological eguption is as follows:.

Articles lacking sources from December Sequesfrum articles lacking sources. 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.
After completion of the treatment, follow-up visits were scheduled every 6 months for monitoring dental plaque control as well as for clinical seqkestrum radiographic assessment Fig.
At the same time as this, new bone is forming known as involucrum. Osteolysis Hajdu-Cheney syndrome Ainhum. Ischaemia Avascular necrosis Osteonecrosis of the jaw Algoneurodystrophy Hypertrophic pulmonary osteoarthropathy Nonossifying fibroma Pseudarthrosis Stress fracture Fibrous dysplasia Monostotic Polyostotic Skeletal fluorosis bone cyst Aneurysmal bone cyst Hyperostosis Infantile cortical hyperostosis Osteosclerosis Melorheostosis Pycnodysostosis.
Although ES is rare, it is important to describe its clinical and histological findings eruptoon helping clinicians diagnose this condition and updating microscopic descriptions.
Unsourced material may be challenged and removed. Rarely, a sequestrum may turn out to be an osteoid osteomaa rare tumor of the bone. Intraoral examination revealed a small white fragment, approximately 0. ES is an uncommon clinical finding.
