objective : tooth eruption has been a subject of extensive scientific studies; and literature is replete with different mechanisms of migration of a tooth from its bony crypt into the oral cavity. however, there is no common ground on the nature and source of the propelling force among the proponents of these theories. the purpose of this study was to explore the possibility of unifying the cur...

Chronic periodontitis, along with associated clinical findings such as pathologic tooth migration, diastema, functional and aesthetic aberrations, poses an immense challenge to a dental professional. These findings convert clinical decision making into a daunting task and adversely affect the prognosis and the treatment plan for the presenting clinical problem. An interdisciplinary approach aim...

Disturbances involving abnormalities in tooth eruption are named ectopia. Transmigration is the name assigned to ectopia in the presence of teeth in areas distant from the alveolar process. Initial angulation of the tooth bud of the second premolar and premature loss of permanent mandibular 1st molars can influence the distal migration of the second premolar. Some studies have observed that ect...

PURPOSE Pathologic tooth migration (PTM) is a tooth displacement which is derived from imbalance of tooth retention force and is dominantly found out in maxillary anterior area. PTM in maxillary anterior area was tried to corrected with periodontal treatment and a clear aligner in this study and the result was evaluated clinically and radiographically. METHODS For the treatment of a patient w...

The application of an external electric field has been shown to enhance the impregnation of resin monomers used in restorative dentistry. Further to experimental investigations that have related the migration of monomers to their electrical properties, additional insight into the conduction mechanism within the tooth can be gained by numerical modelling of the current conduction through the too...

There have been reports on the migration of teeth or implants into the maxillary sinus. We know of only one report on the migration of a gutta-percha point that had been used to fill a root canal into the ethmoid sinus. We report such a case treated with an endoscopically assisted procedure for removal of the foreign body and contemporary endodontic surgical treatment of the tooth.

or those patients with moderate-tosevere periodontal disease, tooth mobility can contribute to discomfort when eating and decreased masticatory and occlusal function. Tarnow and Fletcher described the indications and contraindications for splinting periodontally involved teeth.1 They stated that the rationale for splinting teeth should include the severity of periodontal disease as determined b...

Worn, flat occlusal surfaces and anterior edge-to-edge occlusion are ubiquitous among the dentitions of prehistoric humans. The concept of attritional occlusion was proposed in the 1950s as a hypothesis to explain these characteristics. The main aspects of this hypothesis are: 1) the dentitions of ancient populations in heavy-wear environments were continuously and dynamically changing owing to...

We present an evaluation of the laser ablation Sr isotope data reported by Richards et al. (2008) for a Neanderthal tooth recovered from a site in Greece. Based on an alternative and analytically more robust method of correcting for isobaric interferences present during the analysis the tooth appears to be isotopically homogenous and within uncertainty of the value for modern seawater. If this ...
