Confocal microscopy investigation of enamel subsurface structure following bleaching
Prof Daniel C. N. Chan, Prof William D. Browning, Prof Albert Kwok-Hung Chung & Prof So-Ran Kwon, USA & Korea
Tooth-whitening procedures have been associated with morphological changes in the enamel surface. As early as 1993, Shannon et al. reported significant surface topographic alterations in enamel slabs that had been treated with bleaching solutions for four weeks.1 These findings were confirmed in another study with 30 % H2O2 mixed with PBS.2 Teeth that were bleached in vivo with 35 % carbamide peroxide lost the aprismatic enamel layer and the damage was not repaired after 90 days.3 A confocal laser scanning microscopic study evaluating the micro-roughness of enamel surfaces after bleaching procedures with 10 and 16 % carbamide peroxide found roughness to be significantly higher than in control surfaces.4

Besides the physical and mechanical properties of dental amalgam, one of the main reasons for its success is its clinical simplicity and forgiving technique. The derisory “drill and fill” slogan associated with dental treatment pertinently describes the provision of an amalgam restoration. The usual protocol for amalgam restorations is a single-stage procedure. Following decay excavation and tooth preparation, amalgam is placed directly into the cavity and anatomically curved and burnished. In addition, amalgam restorations are relatively technique insensitive, have favourable wear resistance and high strength, are inexpensive and the post--operative expansion of the material helps “seal” cavity margins.

One step closer to nature: Imitating natural optical properties using lithium-disilicate restorations
Dr Bradley L. Jones, USA
The dental laboratory industry has searched for a material that is structurally sound and highly aesthetic. This material is now available in lithium-disilicate glass ceramic (IPS e.max Press, Ivoclar Vivadent), which is a material like no other in dentistry. The IPS e.max Press lithium disilicate is the first structural (long-lasting) material that is aesthetic, even without layering, when its High Translucency ingots are used.
