Case report of an internal XXXX investigated by light and scanning electron microscopy.

@entity1 @entity174 @entity738 @entity2521 @entity130
There is no doubt that the main reason for an internal grauloma is a traumatic event. The @entity130 may be physical or chemical as in the case of caries or coronal pulpectomy. In most of the cases it is diagnosed by hazard or, when in case of @entity174 or mobility, extraction is the only therapy to be performed. If diagnosed in time root canal treatment may be adequate.In the presented case no single specific event could be determined being the cause of this large internal @entity738 extending from the coronal third of the root canal to the whole crown just leaving an eggshell of enamel that fractured and mimicked mobility of the whole tooth to the @entity1 finally causing him to attend the clinic. As the @entity1 presented severe aggressive @entity2521 and mobility of all teeth it first was assumed that @entity2521 was the ethiological reason in this case. Due to secondary @entity130 the front teeth were labially positioned thus probably being exposed to traumatic insults more frequently. Clinically the upper right medial incisor appeared discoloured darkly not showing the typical pink spot. Without any force the coronal part of the right medial incisor could be removed manually and the root was extracted using a periostal extractor. As it was not suitable to leave the @entity1 with a missing tooth in the front the wound was sutured and as a temporary solution the tooth was reconstructed with composite intraorally and fixed to the neighbour teeth adhesively. The histopathology of the internal @entity738 and the crown was investigated.
