ABSTRACT
Multiple macrodontia is a rare finding and is defined as a condition in which a tooth is significantly larger than normal. Macrodontia may occur as an isolated finding, part of a group of dental anomalies, or as a component of a syndrome with multiple oral and systemic manifestations. The purpose of this paper was to report a case of macrodontia affecting all permanent teeth and exhibiting shovel-shaped maxillary and mandibular incisors and multituberculate molars and premolars. Some or all of this patient's characteristics have been reported in both males and females, with a ratio of 5:2. No inheritance pattern has been established, as these traits have generally occurred spontaneously. As more individuals are identified and as molecular techniques continue to advance, it is probable that a gene or genes responsible for macrodontia and the associated traits will be identified.

PURPOSE: The objective was to directly compare the strength of 6 different resorbable implant plating systems using an in vitro model before and after heating. MATERIALS AND METHODS: Red oak wood was cut and fixated using various resorbable plates and screws. Vertical load was applied and the specimens fractured, while a test machine gathered data. This was repeated after heating of the specimens. RESULTS: Several parameters were analyzed, and force versus displacement curves were plotted for each specimen. CONCLUSIONS: There were no statistically significant differences for total maximum loads between heat-treated and non heat-treated specimens. There were differences in strengths amongst the various systems.
