Smile makeover with direct composite veneers: A two-year follow-up report.

ABSTRACT: Direct composite veneers have gained an important role in dental clinical applications following recently developed materials and techniques in adhesive and restorative dentistry. Direct application on prepared tooth surfaces or even without any preparation, with an adhesive agent and a composite resin material in a single visit is the main procedure as well as the advantage of these restorations. The main aim of this direct procedure is to create minimally invasive and long lasting restorations. As the dental materials and techniques develop, the clinicians also had the chance to mimic the natural dental tissues to create very natural alike restorations in a single appointment. But like all the other dental procedures, direct composite veneers have some indications and contra-indications. These musts have to be understood very well by the clinician before the treatment planning. But this way direct composite veneers would no longer named as 'day savior fillings' and called as minimally invasive, functional and long lasting 'direct aesthetic restorations' that perfectly emulate the natural dental tissues. This article discusses the necessities of direct composite veneers for the ultimate success and illustrates how to perform a minimally invasive, long lasting, functional and natural alike smile makeover with these restorations in a single visit.

Project description:ObjectivesTo investigate both cross-sectional and time-related changes of striatal and whole-brain microstructural properties in different stages of Huntington's disease (HD) using diffusion tensor imaging.Experimental designFrom the TRACK-HD study, premanifest gene carriers (preHD), early manifest HD and controls were scanned at baseline and 2-year follow-up. Stratification of the preHD group into a far (preHD-A) and near (preHD-B) to predicted disease onset was performed. Age-corrected histograms of whole-brain white matter (WM), gray matter (GM) and striatal diffusion measures were computed and normalised by the number of voxels in each subject's data set.Principle observationsHigher cross-sectional mean, axial and radial diffusivities were found in both WM (P ? 0.001) and GM (P ? 0.001) of the manifest HD compared to the preHD and control groups. In preHD, only WM axial diffusivity (AD) was higher than in controls (P ? 0.01). This finding remained valid only in preHD-B (P ? 0.001). AD was also higher in the striatum of preHD-B compared to controls and preHD-A (P ? 0.01). Fractional anisotropy (FA) lacked sensitivity in differentiating between the groups. Histogram peak heights were generally lower in manifest HD compared to the preHD and control groups. No longitudinal differences were found in the degree of diffusivity change between the groups in the two year follow-up. There was a significant relationship between diffusivity and neurocognitive measures.ConclusionsAlterations in cross-sectional diffusion profiles between manifest HD subjects and controls were evident, both in whole-brain and striatum. In the preHD stage, only AD alterations were found, a finding suggesting that this metric is a sensitive marker for early change in HD prior to disease manifestation. The individual diffusivities were superior to FA in revealing pathologic microstructural brain alterations. Diffusion measures were well related to clinical functioning and disease stage.
