Evaluation of Nickel and Titanium Releasing from Titanium-coated Stainless Steel Crowns Regarding Trimming: An In Vitro Study.

Introduction: Stainless steel crowns (SSCs) are the most durable and effective restorations for primary teeth. Titanium-coated SSCs are newer on the market, and this study was conducted to assess the amount of nickel (Ni) and titanium ions released from titanium-coated SSCs, with and without trim, in artificial saliva.

Materials and methods: A total of 60 titanium-coated SSCs were divided into two groups-group I (n = 30, without trim) and group II (n = 30, with trim) and were immersed in 5 mL artificial saliva. The amount of Ni and titanium released in each group was measured by inductively coupled plasma-mass spectrometry on days 1, 7, and 21.

Results: The amount of Ni ion released in group I on day 1 was 0.0096 ppm and reduced on day 7 (0.0091 ppm) and day 21 (0.0088 ppm). Whereas the amount of Ni ion released in group II was the same for all 3 days (0.0096 ppm). The amount of titanium ion released in both groups was the same on all 3 days (0.00108 ppm).

Conclusion: There was no significant difference seen in the mean Ni and titanium ion release between the two groups on all 3 days. The cumulative release of metals from titanium-coated SSCs in each of the groups was significantly lower than the level required to produce any harmful effects. Any of the groups of commercially available SSCs can be used in pediatric dentistry.
