ERUPTION SEQUESTRUM PDF

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 .

Eruption sequestrum ES is an uncommon condition first reported as an osseous fragment overlying the crown of an erupting permanent molar prior to or immediately after the emergence of the cuspal tips through the oral mucosa 1.

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. An unusual eruption sequestrum. 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.

Articles lacking sources from December All articles lacking sources. Microscopic examination revealed large trabeculae with empty lacunae and a minimal amount of existing spongy bone consisting of acute inflammatory cells neutrophils. Clinical and radiographic follow-up visits scheduled at short intervals and then every 6 months revealed normal postoperative conditions.

Openings in this involucrum allow debris and exudates including pus to pass from the sequestrum via sinus tracts to the skin. Unsourced material may be challenged and removed.

The extracted fragment was preserved in formalin for 72 h and submitted to histological processing for microscopic analysis.

Ann Acad Med Singapore ; The histological diagnosis was ES Fig. There was neither history of oral-facial trauma nor abnormalities upon extraoral examination. ES may also be retained by tissue covering the distal marginal ridge of an erupting tooth 2. From Wikipedia, the free encyclopedia.

December Learn how and when to remove this template message. In most cases, the small bone fragments are absorbed completely prior to eruption of the molar. 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. If seen radiographically before tooth eruption, its intraoral appearance may be predicted 1. 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.

In the same case, histopathological examination showed non-vital bone, as reported elsewhere 1,2,5. Thus, a small osseous fragment can occasionally separate from the contiguous bone and emerge through the alveolar bone. This article does not cite any sources.

Thus further investigations should be performed to elucidate its microscopic aspects.

Eruption sequestrae – three case eru;tion. It is a complication sequela of osteomyelitis. A biopsy of the area was excised under local anesthesia. The histological analysis was consistent with non-vital bone and the diagnosis of eruption sequestrum was established.

Rarely, a sequestrum may turn out to be an osteoid osteomaa rare tumor of the bone. The sequestra are surrounded by sclerotic bone which is relatively avascular without a erption supply.

Although ES is rare, it is important to describe its clinical and histological findings for helping clinicians diagnose this condition and updating microscopic descriptions.

ES consists of a small irregular bone spicule, but it can also correspond to the occlusal anatomy of teeth 2. Although ES has been reported as a fragment consisting sewuestrum compact, non-viable bone 1,2,5Watkins 3 described a case composed of dentin and covered in areas by fragments of bacteria-infected cementum.

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.

There was neither history of pain nor evidence of dental caries or abnormality in other soft tissues. Eruption sequestrum – case report and histopathological findings. Views Read Edit View history.

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. Intraoral examination revealed a small white fragment, approximately 0.

A minimal amount of existing spongy bone consisted of acute inflammatory cells infiltrate neutrophils. ES is a mass coronally of the erupting tooth with broader borders 3.
