Abstract:
Stainless steel crowns (SSC) have been extensively used for the restoration of posterior teeth in pediatric dentistry. Nickel is considered an essential trace element and a constituent of stainless steel crowns. There are no pertinent details found on the biodegradation of nickel from the new generation crowns. Therefore, the purpose of the study was to compare the release of nickel from three groups of stainless steel crowns produced by different manufacturers.
Aims And Background:
To evaluate and compare the amount of nickel released from three groups of stainless steel crowns produced by different manufacturers (3M, DNTOTM and KIDS crownTM).
Materials And Methods:
In total, 30 crowns were divided into three groups. Each group consisted of 10 stainless steel crowns. They were further subdivided into four subgroups, each comprising one, two, three, and four crowns respectively. Each subgroup's test materials were placed in separate glass beakers containing 100 mL of artificial saliva at 37°C in an incubator for 4 weeks. The required amount of salivary sample was drawn out of each beaker, and nickel release was analyzed independently on days 1, 7, 14, 21, and 28 by using an Inductively Coupled Plasma-Optical Emission Spectrophotometer (ICP-OES).
Results:
3MTM crowns revealed a comparatively higher nickel release than KIDS crownTM and DNTOTM crowns.
Conclusion:
The study concluded that both DNTOTM and KIDS crownTM showed measurable nickel release in comparison to 3MTM crowns, and the nickel release from 3MTM crowns was greater compared to the experimental groups.
Clinical Significance:
In terms of nickel release, KIDS crown and DNTO crowns are better compared to the standard 3M crowns.
