Replicating a discolored tooth preparation: A technique for effective laboratory communication.

J Prosthet Dent 2018 Apr 5. Epub 2018 Apr 5.

Associate Professor, Department of Prosthodontics, University of Tennessee Health Science Center, College of Dentistry, Memphis, Tenn.

Fabricating a ceramic restoration for a discolored anterior tooth presents a clinical challenge. The dental technician is often hampered by being unaware of the shade of the discolored tooth preparation, which influences the color of the overlying ceramic restoration. A definitive cast that replicates the shade of the prepared tooth helps the ceramist to fabricate a restoration that masks the discoloration appropriately and still achieves the desired optical properties.

Caries detection and quantification around stained pits and fissures in occlusal tooth surfaces with fluorescence.

J Biomed Opt 2018 Mar;23(9):1-7

Yonsei University College of Dentistry, Oral Science Research Institute, Department of Preventive De, Republic of Korea.

Occlusal discoloration due to staining frequently occurs on the pits and fissures of teeth. Noncariogenic discoloration (non-CD) refers to the attachment of staining chromogens to sound surfaces, whereas cariogenic discoloration (CD) represents the discoloration of porous structures due to bacterial metabolites and mineral loss from the enamel surface. This study evaluated whether it is possible to distinguish between non-CD and CD on stained occlusal surfaces with fluorescence assessed by the quantitative light-induced fluorescence (QLF) technology.

Int Endod J 2018 Feb 26. Epub 2018 Feb 26.

Endodontics Section, Department of Stomatology, School of Dentistry, University of Sevilla, Sevilla, Spain.

Regenerative endodontic procedures (REPs) are biologically based procedures planned to replace damaged tissues, including dentinee and root structures, as well as cells of the pulp-dentine complex. Effective sterilization of the root canal is essential in REPs, and antibiotics have been widely used to disinfect root canals. The aim of this paper was to review the scientific literature on (i) Effectiveness of antibiotics used in REPs against bacteria implicated in endodontic disease; (ii) Scientific evidence supporting the use of topical antibiotics in REPs; (iii) Clinical implications of the use of antibiotics in REPs and the possible side effects; (iv) Effect of antibiotics on dental pulp stem cells; and (v) Ongoing research on the use of antibiotics in REPs.

Background: Tooth discoloration may be caused by intrinsic or extrinsic stains or a combination of both. There are 2 major approaches to removing the stains, including the chemical mechanism using peroxides for tooth bleaching and the mechanical mechanism using abrasives in prophylactic pastes and dentifrices to remove stains, resulting in a whitening effect. Attempts have also been made to add a low concentration of peroxides to dentifrices to enhance their abrasive cleaning to remove tooth stains. Read More
