The influence of preformed metal crowns versus zirconia crowns on the diagnostic quality of magnetic resonance images.

Purpose: The purpose of this study was to investigate and compare in vitro the influence of preformed metal crowns (PMC) versus zirconia crowns (ZC) on the extent of artifact formation and the diagnostic quality of magnetic resonance imaging (MRI).

Methods: Standard crown tooth preparations were performed on Typodont models. PMC and ZC were cemented on all primary molar teeth (n = 8) of the respective models.

Root canal instrumentation efficacy of non-fused and fused primary molar roots: a micro-computed tomography study.

Purpose: Pulpectomy may be indicated in restorable primary teeth exhibiting irreversible pulpitis or pulpal necrosis. The purpose of this study was to compare the cleaning and shaping efficacy of NiTi systems (Reciproc Blue and MTwo) with manual stainless-steel instrumentation in primary molars using micro-CT analysis.

Methods: Fifty-seven maxillary second primary molars were scanned using micro-CT.

Root canal morphology of primary maxillary second molars: a micro-computed tomography analysis.

Aim: Successful endodontic treatment of primary teeth requires comprehensive knowledge and understanding of root canal morphology. The purpose of this study was to investigate the root canal configurations of primary maxillary second molars using micro-computed tomography.

Methods: Extracted human primary maxillary second molars (n = 57) were scanned using micro-computed tomography and reconstructed to produce three-dimensional models.
