Vertical root fracture: a case report.
A case report involving vertical root fracture in an endodontically treated mandibular left first molar is presented. Pain and extensive tissue damage occurred in the area 2 years after root canal therapy. The periapical radiograph suggested endodontic failure, and re-treatment was initially considered. However, the problem was related to a complete vertical root fracture in the distal root, which was only visible after removal of the gold crown. The tooth was extracted because severe periodontal destruction had been caused by the root fracture.

Histology and lysosomal cytochemistry of the postsurgically inflamed dental pulp after topical application of steroids. I. Histological study.
The purpose of this study was to histologically investigate steroid effects on the dental pulp. Three steroid preparations, hydrocortisone, betamethasone and triamcinolone, were locally applied to the exposed pulp tissue in rat incisor after pulpectomy. After 24 h, the effects on the tissues were assessed by light microscopy. The results showed that topical application of corticosteroids as an intracanal medicament reduced inflammatory changes in the pulp as compared with controls. Furthermore, triamcinolone and betamethasone demonstrated more potent anti-inflammatory effects than did hydrocortisone.
