Abstract

Aim: This study aimed to spectrophotometrically analyze saliva for metal ion release in patients prior to and post cementation of either cobalt chromium or nickel-chromium alloy crowns–In vivo. Materials and methods: Twenty participants selected, divided into two groups, each group having 10 participants, Group 1—Cobalt chromium crown fabrica ted and cemented and Group 2—Nickel-chromium crown fabricated and cemented. Saliva was collected before cementation of the crown and 1st day, 7th day and 15th day after cementation of the crown and subjected to spectrophotometric analysis by atomic absorption spectrophotometer. Results: The statistical analysis showed that there were no traces found of cobalt and chromium ions in the sample of Group 1 participants before cementation of the crown. After cementation of cobalt chromium crown traces of cobalt and chromium were found on Days 1, 7 and 15. The traces were found on 1st day which increased on Day 7 and then a decline was observed in the number of ions on Day 15. In Group 2, no traces were found of nickel and chromium ions in samples of participants before cementation of the crown. After cementation of nickel chromium crown traces of nickel and chromium were found on Days 1, 7 and 15. The traces of ions were found on Day 1 which increased by Day 7 and then a decline was observed in the number of ions on day 15. Conclusion: The results showed that compared to Group 1 the release of metal ions was found to be more in Group 2.
