Management of an avulsed primary incisor.

The case describes the management of an avulsed maxillary central primary incisor of a 3 1/2-year-old girl. The tooth was retained in the oral cavity for 30 min. After replantation it was splinted for 17 days.

Adhesion of a glass ionomer cement to human radicular dentine.

The adhesion of cements to root canal surfaces is a crucial factor for strengthening non-vital teeth--weakened due to extensive loss of tooth structure--by cemented posts. The aim of this study was to determine the tensile strength of a glass ionomer cement (Ketac-Cem) on root canal walls following pretreatment with conditioners. Upon cleaning and shaping, 56 straight root canals--divided into seven groups--were conditioned with one of the following solutions: NaOCl (1%) + EDTA (20%), H3PO4 (37%), HNO3 (2.

Detection of infection in postoperative orthopedic patients with technetium-99m-labeled monoclonal antibodies against granulocytes.

A prospective study of 106 orthopedic patients was performed for the detection of infection in the early postoperative stage using 99mTc-labeled murine Mabs directed against epitopes on granulocytes. Accuracy was 81% in the hips (n = 26), 81% in the thigh (n = 21), 84% in the knee (n = 19), and 100% in the tibia (n = 27). The technique did not work well in the spine where false-negative results were observed in the three patients studied.
