DENTSPLY DeTrey SmartLite PS Manual page 15

SmartLite™ PS
The other half of the restorations is light-cured with SmartLite PS. The curing time for each
2mm increment of composite is 10 seconds.
The investigators monitor the performance of the restorations with regard to any report of
post-operative sensitivity or other side effects received from the patient and/or when the
respective restorations become available for inspection during routine examinations.
Patient/Case Selection
Routine patients in need for direct tooth-coloured posterior restorations (Class I and II
cavities in molars and premolars). Tooth to be vital on the day of treatment, with no
symptoms of pulp inflammation/irritation, and not in need of direct pulp capping or endodontic
treatment. There should be no hypersensitivity or sensitivity to percussion.
For inclusion into the study, the following additional requirements have to be met:
Successful cavity isolation (no contamination)
Patient was expressly asked to report back if any sensitivity occurs
Light output was measured immediately after treatment and exceeded 300mW/cm²
for the halogen curing light and 720 mW/cm² for SmartLite PS.
Reporting
Reports to DENTSPLY are provided by the investigators by means of a set of forms for each
restoration to be monitored.
Interim report August 2003:
First data from 4 investigators were analysed and prove that for all criteria measured there is
no difference in safety and efficacy between a standard halogen light with a curing time of 20
seconds per increment and SmartLite PS with a curing time of 10 seconds per increment for
the curing of posterior composite restorations. Data on post-operative sensitivity are provided
in Figure 11.
