Tooth eruption and migration theories: can they account for the presence of a 13,000-year-old mesiodens in the vault of the palate?

A case of a mesiodens in the vault of the palate of a skull estimated to be approximately 13,000 years old is presented. The currently cited theories of tooth eruption were considered, and it was concluded that only the newly formulated BVT (blood vessel thrust) theory of tooth eruption can account for the migration of this mesiodens into that position.

Oral-dental findings in a case of Maffucci's syndrome.

A case of Maffucci's syndrome (MS) in a 17-year-old Caucasian female is presented with a thorough intraoral examination. The prominent finding was recurrent gingival hyperplasia affecting both the free and attached gingiva with deep periodontal pockets, tooth mobility, pathological tooth migration, and severe alveolar bone loss. Furthermore, the pattern of alveolar bone destruction, in many ways, resembled that of localized juvenile periodontitis. Although there is always the possibility that these oral features may not be related with the syndrome, we suggest a careful dental and periodontal examination in future cases, which we believe will help develop a better description of oral findings in MS.

Tooth eruption: theories and facts.

The mechanisms of tooth eruption (i.e., the answer to the question of how and why teeth erupt) has been a matter of long historical debate. This review focuses on human and other mammalian teeth with a time- and spacewise limited period of eruption and analyzes recent observations and experimental data on dogs, rats, primates, and humans in a framework of basic biological parameters to formulate a guiding theory of tooth eruption. Acknowledging basic parameters (i.e., that teeth move in three-dimensional space, erupt with varying speed, and arrive at a functional position that in inheritable) eliminates a number of previously held theories and favors those that accommodate basic parameters, such as alveolar bone remodeling in association with root elongation, with possible correction factors in the form of cementum apposition and periodontal ligament formation. We have critically analyzed, summarized, and integrated recent findings associated with preeruptive movements of developing teeth, the intraosseous stage of premolar eruption in dogs, molar eruption in rodents, and premolar and molar eruption in primates. The variable speeds of eruption are particularly important. We conclude with basic principles of tooth eruption--that is, the type of signals generated by the dental follicle proper, the conditions under which teeth are moved and the clinical understanding to be derived from this knowledge.

[Experiences with Burstone's segmented arch technic in the adult dentition].

In comparison to the straight wire technique the segmental arch approach offers numerous biomechanical and clinical advantages. Three typical examples: controlled tooth movement, en masse space closure and deep overbite correction serve to show the spectrum and the efficiency of the segmented arch technique.

[Early deciduous tooth loss--the mature or immature eruption of their permanent successors].

On the basis of 147 panoramic radiographs of 49 patients, this study investigated the influence of the premature loss of deciduous teeth on the formation of their permanent successors at the time of their eruption. Furthermore the study investigated the eruptive movement of the successor teeth at the time of eruption. In addition to detecting the accelerated emergence of still immature successor premolars, the study also determined that the extraction ot the deciduous molars before the age of eight years delayed the eruption of the permanent successors given the absence of an infected deciduous tooth with abscess formation. In relation to the eruptive movement of the permanent molars due to the premature loss of the second deciduous molar, the study ascertained a mesial movement of the first permanent molars and an accelerated eruption of the second permanent molars.
