Animal studies have shown that a periodontal ligament may be produced around a titanium implant when it is in contact with fractured and retained roots. Formation of cementum and attachment connective tissue around titanium implants confirms that cementum progenitor cells are located in the periodontal ligament, since cementum and periodontal ligament are present at the implant-root interface, ...

Concrescence signifies a rare developmental alteration, most commonly in maxillary molars,where two fully formed teeth with separate root canal structures are fused with cementum. Clinical detection is difficult due to lack of enamel involvement and radiographic detection may be challenging, as two dimensional images may be misdiagnosed as overlap, superimposition or close proximity of roots. S...

BACKGROUND Equine incisors are subjected to continuous occlusal wear causing multiple, age related changes of the extragingival crown. It is assumed that the occlusal wear is compensated by continued tooth elongation at the apical ends of the teeth. In this study, μCT-datasets offered the opportunity to analyze the three-dimensional appearance of the extra- and intraalveolar parts of the enamel...

That Paget's disease of bone may affect the jaws has been known since Moore's (1923) report of a case in which there was a bony tumour of the maxilla together with osteoporosis circumscripta of the frontal region, though until quite recently the disease in this site has been considered rare. Osteoporosis circumscripta itself has now been identified with an early phase of Paget's disease (Sosman...

This investigation studied the effect of the sulcular and periodontal ligament injection techniques on certain periodontal tissues. Eleven monkeys (Macaca nemistrina) were given injections of local anesthetic into the sulcular tissue or the periodontal ligament on the lingual side of maxillary molars. Contralateral teeth served as controls. After three months biopsies were taken and made into h...

Rostral mandibular and maxillary factures are the most common type of fractures sustained to the head of the horse. They are most often seen in younger animals with deciduous or mixed deciduous and permanent dentition. These injuries are frequently seen to arise from falls or kicks, biting behavior with tie-up chains, or involvement with window bars or mangers. Rare cases are iatrogenic from de...

Gardner’s syndrome is characterized by a triad of intestinal polyposis, which ultimately become malignant, soft-tissue neoplasms such as desmoid tumors and fibromas, and osteomas, particularly of the skull and facial bones. A case report of bilateral osteomas of the coronoid process resulting in limited incisal opening in a 12-year-old girl and review of the pertinent literature is presented. G...

The many risks and considerations involved when performing an extraction can present a particular challenge to the dental professional, especially regarding management of bleeding. Many factors can increase the potential difficulty of an extraction, including difficult root morphology and some inflammatory disorders, but with a thorough medical history, a complete pre-operative examination, and...
