Dental radiation dosimetric maps from intensity-modulated radiation therapy planning for head and neck cancers.

Background: The purpose of this study was to create dental radiation maps to calculate the mean dose to individual teeth, maxilla and mandible using intensity-modulated radiation therapy (IMRT).

Methods: Eighteen common clinical settings were chosen. Radiation plans were extracted, and each tooth was contoured at its junction with the gingiva and labeled based on the Universal/American numbering system.

Congenital granular cell lesion of the tongue: a report of two cases and review of the literature.

The congenital granular cell lesion most commonly occurs on the maxillary or mandibular alveolus of neonates. Extra-alveolar congenital granular cell lesion is exceptionally rare, with only 10 cases reported. Two additional cases occurring on the tongue are presented with a description of the clinical, histopathologic, and immunohistochemical features.
