Abstract:Objective To explore the effectiveness of application of low-dose multi-spiral CT in dental
examinations for children with embedded teeth. Methods A total of 84 children with suspected
embedded teeth were selected and divided randomly into three groups with 28 cases in each group.Then,
all the groups were scanned by a multi-slice spiral CT with a tube voltage of 120 kV, 100 kV and 80 kV
respectively. Additionally, all the other parameters were same so as to compare the CTDIvol (CT Dose
Index Volume), DLP (Dose-Length Product) and imaging quality between each two groups.Results
The CTDvol of the groups scanned with the tube voltage of 80 kV and 100 kV were 33% and 59% of
that of the other group respectively. The imaging quality of the three groups was up to standard and can
meet the diagnostic requirement.Conclusion CT Scanning with the tube voltage of 80 kV has proven
its effectiveness indental examinations for children with embedded teeth, which can ensure excellent
imaging quality and is worthwhile to be promoted.
