    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.

    Does the Use of a "Walking Bleaching" Technique Increase Bone Resorption Markers?
    Oper Dent 2018 May/Jun;43(3):250-260. Epub 2018 Mar 13.
    Objective: This randomized clinical trial evaluated the effect of 35% hydrogen peroxide in comparison with 37% carbamide peroxide in a nonvital bleaching technique of "walking bleaching" (four sessions of treatment) on periodontal markers: nuclear factor kappa B-ligand (RANK-L-process of root resorption marker) and interleukin 1β (IL-1β-inflammatory response marker).

    Methods And Materials: Fifty volunteers presenting with discoloration of nonvital teeth and endodontic treatment in good condition participated.

    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.

    Introduction: Two fundamental assumptions for teeth treated with regenerative endodontic procedures (REPs) are (1) that the clinical outcome is comparable with the traditional techniques of calcium hydroxide apexification and mineral trioxide aggregate apical barrier techniques and (2) that REPs will result in further root maturation.

    Methods: A systematic review of the electronic databases (Scopus, PubMed, and Web of Science) involved a search for studies that used quantitative assessments of root maturation. The search terms were "dental pulp," "regenerative endodontic therapy," "revascularization," and "revitalization. Read More

    Bovine Tooth Discoloration Induced by Endodontic Filling Materials for Primary Teeth.

    This study evaluated the discoloration potential of endodontic materials used in primary teeth. Dentine-enamel blocks were prepared from 75 bovine teeth, assorted in five experimental groups ( = 15). The tested materials included an MTA-based material; zinc oxide and eugenol cement (ZOE); Vitapex; and calcium hydroxide thickened with zinc oxide (Calen + ZO). Read More

    Functional and esthetic rehabilitation of a child with amelogenesis imperfecta: a case report.
    Gen Dent 2017 May-Jun;65(3):e18-e20
    Amelogenesis imperfecta (AI) is a tooth disorder characterized by the abnormal development of the enamel in response to mutations in the genes involved in amelogenesis. The objective of this article is to present the clinical case of a child with AI in the primary dentition phase. A 4-year-old boy was presented to a clinic by his mother, who complained that her son's smile esthetics were compromised by "weak and yellow teeth. Read More

    Rare sequelae in the permanent successor due to trauma in the primary incisor: a case report.
    Gen Dent 2017 May-Jun;65(3):62-64
    Severe dental trauma-such as intrusion or avulsion-to the primary dentition in infants and toddlers may cause developmental disturbances in the permanent successor. In this case, a 9-year-old boy was referred for treatment due to the absence of his permanent maxillary right central incisor. The mother reported avulsion of the corresponding primary tooth when the patient was 2 years old. Read More

    [Comparison of clinical effects of Co-Cr alloy cast post-core and everStick fiber post in restoration of labially or lingually inclined maxillary central incisor].

    Department of Prosthodontics, Shanghai Stomatological Disease Center, Shanghai Stomatological Hospital. Shanghai 200031, China.
    Purpose: To compare the clinical effect of Co-Cr alloy cast post-core and everStick fiber post in restoration of maxillary central incisor with labial or lingual inclination, and provide theoretical basis for clinical application.

    Methods: Ninety-seven labially or lingually inclined maxillary central incisors were treated in our hospital from March 2012 to March 2014. The patients were randomly divided into group A (n=49) and group B (n=48), and received post -core and crown restoration. Read More
