RESUMO
A clinical study was performed to determine if placement of an amalgam retroseal resulted in elevated blood mercury levels. Ten subjects had blood drawn 7 days before and immediately before placement of an amalgam retroseal. Postoperative blood draws occurred at 7 and 30 days. Blood samples were analyzed for mercury content by Cold-Vapor Atomic Absorption Spectrophotometry. No statistically significant increase in blood mercury levels was detected at 7 and 30 days after placement of an amalgam retroseal as compared with preoperative levels (p = 0.97). Findings support the hypothesis that placement of an amalgam retroseal does not result in significant elevations of blood mercury levels.

Dens invaginatus is an anomaly which has numerous and complex forms. Whenever endodontic therapy involving such a tooth becomes necessary, the clinician must be aware of the various treatment modalities available to facilitate proper care. Presented in this case report is a maxillary lateral incisor having the anomaly dens invaginatus in which both surgical and nonsurgical treatment was required. The surgical phase was facilitated through the use of ultrasonic instrumentation.
