Replacement resorption is the most frequent complication after delayed replantation of avulsed teeth. The resorption can interfere with the development of the alveolar ridge and lead to tilt of the adjacent teeth in growing patients. However, there is no means of arresting or reversing the process. Recently decoronation is recommended by International Assocaition of Dental Traumatology as the optimal choice to manage it. This paper demonstrates the procedure and effectiveness of the decoronation by literature review and a case report with 4-year follow-up...

Decades of collecting from exposures of the Upper Cretaceous Tombigbee Sand Member of the Eutaw Formation and Mooreville Chalk in Alabama, USA has produced large numbers of isolated Cretalamna (sensu stricto) teeth. Many of these teeth had formerly been assigned to the extinct Late Cretaceous shark Cretalamna appendiculata (Agassiz, 1843), a taxon that is now considered largely restricted to the Turonian of Europe. Recent studies have shed light on the diversity of Late Cretaceous Cretalamna (s.s.) taxa, and here we recognize a new species from Alabama, Cretalamna bryanti...

This issue of the Anatomical Record is the first of a two-volume set that focuses on new investigations into behavioral correlates of muscle functional morphology. Much of the research on functional morphology and adaptation to specific functional niches focuses on the shapes of hard-tissues-bones and teeth. Investigations into soft-tissue anatomy tend to be predominantly descriptive with only brief allusion to ontogenetic or evolutionary origins of structures. When muscles are included in analyses of functional systems, their function tends to be oversimplified-usually considered a simple force vector connecting two osteological points, with the force treated as a constant derived from some simple calculation of muscle size...

BACKGROUND: Traumatic tooth avulsion requires an urgent intervention to replant the tooth. Prolonged post-injury dry extra-oral conditions worsen the prognosis and increase the risk of root resorption. Fluoride has the potential to delay replacement resorption. Calcium silicate cements (CSC) are used to seal the root canal system and to stimulate periapical regeneration in immature open apex teeth (apexification). This report suggests the application of a novel fast-setting CSC with fluoride for apexification in an attempt to hinder root resorption...

Atherosclerosis, a chronic inflammatory disease in arterial blood vessels, is one of the major causes of death in worldwide. Meanwhile, periodontal disease is a chronic inflammatory disease caused by infection with periodontal pathogens such as P. gingivalis (Porphyromonas gingivalis). Several studies have reported association between periodontal infection and atherosclerosis, but direct investigation about the effects of periodontal treatment on atherosclerosis has not been reported. We have planned Japanese local clinics to determine the relationship between periodontal disease and atherosclerosis under collaborative with medical and dental care...
