Abstract:

The purpose of this study was to evaluate the effect of camera sleeve decontamination protocols and compare their accuracy to single-use alternatives. Five extracted human teeth were set into a gypsum stone model and prepared for various indirect restorations. A baseline optical impression was completed with a bench-top scanner. One hundred sixty optical impressions were completed using a calibrated or uncalibrated intraroral scanner (CEREC PrimeScan, Dentsply Sirona) and a sterilizable, autoclavable with single-use glass or disposable plastic camera sleeve (n equals 10). Decontamination protocols included dry heat sterilization or high-level disinfection with scans at baseline, and after 25 and 50 cycles. Individual optical impressions were compared to baseline using the prepared teeth surfaces as references and overlayed using 3-dimensional best fit superimposition. Data were analyzed with Kruskal-Wallis and Mann-Whitney U tests (alpha equals 0.05). No significant differences in median linear distance were found regardless of sleeve type, decontamination protocol, or calibration status (p greater than 0.05). All groups demonstrated statistically similar linear disparities ranging from 11.78-14.00 microns. The most precise sleeves were single-use, although not statistically different than the multi-use sleeve. Camera sleeve type, decontamination protocol, and calibration status of the intraoral scanner did not significantly impact the accuracy of the optical impressions, Any of the currently available camera sleeves can provide similar accuracy in a clinical setting.
