  • Esthetics/Cosmetic Dentistry Achieving highly esthetic anterior restorations with ideal assessment, communication, and technique

    Scott Finlay, DDS, FAGD, FAACD
    Nelson Rego, CDT, AAACD
    2014 Nov/Dec; 62(6):36. 

    Microesthetics are those criteria related to the subtle intricacies of shade, textures, translucencies, and surface effects that make teeth look like teeth. The utilization of a common nomenclature and quantitative means of communication between the restorative dentist and the laboratory ceramist are at the core of success. The use of cross-polarization filters eliminates spectral artifacts typically found in flash photography, and the use of a color-corrected master die system provides the ceramist a method to calibrate shades on the lab bench by capturing images that are similar to what is observed clinically.

  • The Science of Color Comparison between visual and instrumental methods for natural tooth shade matching

    Welson Pimentel, DDS, MSc
    Rodrigo Tiossi, DDS, PhD
    2014 Nov/Dec; 62(6):47. 

    This study compared the accuracy of shade matching by both visual and instrumental methods to determine whether the instrumental method would significantly improve shade matching. Shade matching by clinicians using the instrumental method presented more agreement, and was more effective, than shade matching by clinicians using the visual method.

  • Veneers Direct or indirect composite veneers in anterior teeth: which method causes higher tooth mass loss? An in vitro study


    Alessandra Nunes Machado, DDS
    Fabio Herrmann Coelho-de-Souza, DDS, MSD, PhD
    Juliana Nunes Rolla, DDS, MSD, PhD
    Maria Carolina Guilherme Erhardt, DDS, MSD, PhD
    Flavio Fernando Demarco, DDS, PhD
    2014 Nov/Dec; 62(6):55.

    This in vitro study sought to quantify the different mass loss from preparation techniques used for direct and indirect veneers. Teeth undergoing veneer preparations demonstrated a statistically significant mass loss compared to unprepared teeth. Indirect ceramic veneer preparations produced more mass loss than direct composite veneer preparations (P ≤ 0.01).

    Antiplatelet and anticoagulant agents have been extensively used for the prevention and management of arterial and venous thrombi. These medications are associated with an increase in bleeding time and risk of intraoperative and postoperative hemorrhage in the dental office. A survey of 50 cardiologists was conducted regarding suggested guidelines for dentists in the management of patients who are taking anticoagulant medication.

    Anesthesia and Pain Control Mepivacaine: a closer look at its properties and current utility

    William G. Brockmann, DDS, PhD
    2014 Nov/Dec; 62(6):70. 

    Mepivacaine is commonly used in medically compromised patients in a formulation with a vasoconstrictor, or in pediatric populations in a formulation without a vasoconstrictor. It is important to understand the unique pharmacologic characteristics of mepivacaine in order to minimize the potential for inadvertent toxicity.

All 5 materials were evaluated as severely cytotoxic on the first day. With the exception of Adper Single Bond Plus, toxicity continued to Day 28 for all compounds. The utmost care must be taken to prevent contact between dental bonding agents and adjacent tissues.

    This study used atomic force microscopy to evaluate the effects of an in-office dental bleaching protocol on the surface roughness of 3 resins: microfilled, microhybrid, and nanofilled. Based on the results, it was concluded that in-office bleaching with 35% hydrogen peroxide-based gel increased the surface roughness of microfilled, microhybrid, and nanofilled resins significantly.

    The purpose of this study was to determine the efficacy of toothbrushes that advertise self-disinfecting, antimicrobial properties due to the inclusion of silver nanoparticles or chlorhexidine in the bristles. The chlorhexidine-coated toothbrushes had significantly greater percent reduction in S. mutans compared to the control or silver nanoparticle toothbrushes. Neither the chlorhexidine-coated nor the silver nanoparticle toothbrushes had a significant reduction in C. albicans compared to the control. Neither of the antimicrobial toothbrushes delivered the advertised claim of a 99.9% reduction with either microorganism.

    This single center, randomized, small study sought to investigate whether there is a relationship between gum chewing and the presence of symptoms associated with temporomandibular disorder. Arthralgia was reported in groups that chewed gum 3 hours/day and >3 hours/day. Myofascial pain was reported in groups that chewed <1 hour/day, 1-2 hours/day, and >3 hours/day. There was a connection between chewing gum more than once a week and masseter hypertrophy.
