Conservation of Bone Homografts in Cialit: 5 Years Clinical Experience
The technique that we use for conserving bone homografts requires the chemical substance 2-(ethyl 1-mercuro-mercapto)-5-benzoxazole-carbonate-sodium, known commercially as Cialit. This white powder carbonizes when heated, without melting; it is used in water solution with bidistilled water in various dilutions. Bone segments are placed into air-tight glass containers filled with a solution of Cialit (1: 5000) stored at +4 °C and sheltered from light. After 15 days the bone can be used for grafts. The solution must be changed regulary every 15–20 days. The maximum period of conservation advised by its manufacturers is about 12 months. The only caution necessary when using segments in Cialit is that they should be thoroughly washed in a physiological solution before clinical use so as to eliminate completely the conversation solution.
