Behavioral changes, unbalanced diet, various medical conditions and medications inducing acid regurgitation or influencing saliva composition and flow rate, trigger tooth erosion. Awake and sleep bruxism, which are widespread nowadays with functional disorders, induce attrition. It has become increasingly important to diagnose early signs of tooth wear so that proper preventive, and if needed, restorative measures are taken. Such disorders have biological, functional, and also esthetic consequences. Following a comprehensive clinical evaluation, treatment objectives, such as a proper occlusal and anatomical scheme as well as a pleasing smile line, are usually set on models with an anterior teeth full-mouth waxup, depending on the severity of tissue loss. Based on the new vertical dimension of occlusion (VDO), combinations of direct and indirect restorations can then help to reestablish anatomy and function. The use of adhesive techniques and resin composites has demonstrated its potential, in particular for the treatment of moderate tooth wear. Part I of this article reviews recent knowledge and clinical concepts dealing with the various forms of early restorative interventions and their potential to restrict ongoing tissue destruction.","PeriodicalId":88322,"journal":{"name":"The European journal of esthetic dentistry : official journal of the European Academy of Esthetic Dentistry","volume":"6 1","pages":"20-33"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29740206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also in fixed prosthesis, discolorations represent an esthetic limit, particularly in the case of all-ceramic restorations. In fact, the final esthetic result can be compromised by the grey radiated through the coping and soft tissue.Purpose: The aim of the study was to evaluate the masking ability of Procera alumina restorations.Materials and methods: Clinical evaluation was investigated by using tests of discolored teeth. Each abutment, classified with Natural Die Material (Ivoclar Vivadent), were manufactured three alumina copings with thickness of 0.4, 0.6, and 0.8 mm, respectively. Masking ability for each coping was evaluated in relation to the degree of discoloration. On the basis of the results obtained, seventeen discolored teeth, treated with Procera alumina restorations, were evaluated. Color match, porcelain surface, marginal discoloration, and marginal integrity were clinically examined following modified CDA/Ryge criteria.Conclusion: The Procera AllCeram alumina system seems to be a reliable and excellent technology for the prosthetic treatment of moderate and serious discolored anterior teeth with an exceptionally natural look.","PeriodicalId":88322,"journal":{"name":"The European journal of esthetic dentistry : official journal of the European Academy of Esthetic Dentistry","volume":"6 1","pages":"76-86"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29740103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CIE Lab values were determined for all maxillary anterior teeth. Intraclass correlation coefficients (ICCs) were used to statistically analyze intra-and inter-device repeatability for different tooth regions. Color differences (ΔE) between measurements were also computed to evaluate the clinical acceptability of repeatability values. The data were evaluated using analysis of variance and Bonferroni's adjustment to control for multiple testing. Differences were deemed significant when P < 0.016.Results: The three color-measuring devices generally exhibited high repeatability of color coordinates for all tooth regions (ICC > 0.516-0.986, ΔE < 3.03). In contrast, inter-device repeatability was lower for all tooth regions (ICC = 0.010-0.922, ΔE = 4.06-16.04).Conclusions: High intra-device repeatability of color coordinates could be achieved for all tooth regions when the same color-measuring device was used. However, because of low inter-device repeatability, results using different color-measuring devices are not comparable.","PeriodicalId":88322,"journal":{"name":"The European journal of esthetic dentistry : official journal of the European Academy of Esthetic Dentistry","volume":"6 4","pages":"428-35"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30380728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 231 extracted anterior teeth were randomly divided into three groups (n = 77 in each group) with comparable mean baseline L*-values (68.24 ± 0.8): a non-bleached control group A, a 15% carbamide peroxide group B (5 bleaching intervals of 8 hours), and a 38% hydrogen peroxide group C (3 intervals of 15 minutes). Durability of bleaching was assessed by comparing CIE-L*a*b* data after intervals of 2, 4, 12, and 26 weeks from baseline. Both bleaching regimes initially produced a highly significant increase in lightness parameter L*, with no significant difference between the respective bleaching regimes (B: 68.23 / 72.48; C: 68.32 / 73.25). Six months after starting the trial, L*-values for group B yielded no significant differences compared to baseline (69.55), whereas L*-values for group C were still significantly raised (69.91), despite a highly significant decrease when compared to initial bleaching results. In both treatment groups, there was a lasting response to bleaching in terms of CIE-a* and -b* value decreases. Results for both home- and in-practice regimes were found to be similar for about 12 weeks. However, in-office results were longer lasting, despite the shorter treatment intervals. Summarized bleaching effects, in terms of delta E values, revealed no significant differences between treatment groups and the control group after 6 months, indicating an abatement of the bleaching results achieved.","PeriodicalId":88322,"journal":{"name":"The European journal of esthetic dentistry : official journal of the European Academy of Esthetic Dentistry","volume":"6 3","pages":"342-56"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30107690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
