Foreign-body (silica) granuloma of the lip.

A foreign-body granuloma may occur in the lip secondary to traumatic implantation of dirt and sand. Several recommendations for the clinician encountering such contaminated wounds follow. Debridement of the wound and copious flushing are of primary importance as a preventive measure. The patient should be informed of possible sequelae and advised to seek treatment if nodules occur in later years. The development of a granulomatous response necessitates initial surgical intervention to establish the histologic diagnosis; however, repeated surgical procedures are not indicated unless subsequent enlargements cannot be resolved by intralesional injection of steroids. Last, it must be emphasized that a histologic diagnosis of a granulomatous lesion obligates the oral and maxillofacial surgeon to request additional studies to rule out a systemic involvement.

[A comparative study of 2 capacitor discharge X-ray units].

Two capacitor discharge X-ray units of different make were compared. The same radiological examinations were carried out with both units and the radiation exposure for every examination was measured on a Rando phantom with calibrated LiF-TLD Teflon discs. A large difference in radiation exposure for the same image quality was found between the two units. Factors such as the use of rare earth intensifying screens with capacitor discharge X-ray units, independent tube current settings and automatic charge replenishment are stressed.
