The use of micro-CT with image segmentation to quantify leakage in dental restorations [PDF]

Dental Materials, 2015
To develop a method for quantifying leakage in composite resin restorations after curing, using non-destructive X-ray micro-computed tomography (micro-CT) and image segmentation.Class-I cavity preparations were made in 20 human third molars, which were divided into 2 groups. Group I was restored with Z100 and Group II with Filtek LS.

Evaluation of dental composite shrinkage and leakage in extracted teeth using X-ray microcomputed tomography [PDF]

Dental Materials, 2009
Use X-ray microcomputed tomography (microCT), to test the hypothesis that composite shrinkage and sites of potential leakage in human teeth are non-uniformly distributed and depend on cavity geometry and C-factor.Two holes of equal volume but different dimensions were drilled into the exposed dentin of extracted human molars.
