Eruption sequestrum - case report and histopathological findings
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. This paper reports a case of unilateral eruption sequestrum in a 7-year-old Brazilian boy and describes its histopathological findings. A white small fragment, 0.5 cm in diameter, with hard consistency, irregular shape and located on the occlusal surface of the erupting mandibular left first molar was excised. Microscopic examination revealed large trabeculae with empty lacunae and a minimal amount of existing spongy bone consisting of acute inflammatory cells (neutrophils). Signs of necrosis were found on the periphery. The histological analysis was consistent with non-vital bone and the diagnosis of eruption sequestrum was established. Clinical and radiographic follow-up visits scheduled at short intervals and then every 6 months revealed normal postoperative conditions.
