Changes in color, shape, and texture are commonly cited as grounds for complaint, which are sometimes characterized by details, making the work challenging. The objective of this work is to report the planning and execution of a clinical case of smile harmonization with ceramic laminates for remodeling smile.CASE DESCRITION: A male patient consulted a specialist to refine the appearance of his smile that already had a satisfactory pattern of color and texture. The planning was started using digital smile planning, followed by diagnostic waxing of the elements involved. The planning approval took place through the Mock up. The dental grinding performed was minimal and followed a silicone wear guide. The pieces were made in lithium disilicate and installed under absolute isolation according to the cementing protocol of the material. The finishing and polishing completed the installation of the pieces, removing excesses and guaranteeing periodontal compatibility.CONCLUSION: We conclude that indirect aesthetic treatments currently have a minimally invasive character and are highly accepted due to their ability to remodel the smile with perfection and naturalness.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15448/1980-6523.2018.1.28767","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49426202","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}

The transmission of S. mutans can occur between people, often within families. The present study aimed to evaluate the intrafamily genetic pattern of S. mutans through partial sequencing of the gene that encodes the glucosyltransferase β (gtfB) enzyme.METHODS: We previously analyzed saliva samples from 40 individuals from nine families, and it was obtained 64 isolates biochemically characterized as S. mutans. The isolates were evaluated by random amplification of polymorphic DNA (RAPD). Those with greater similarity were characterized by partial sequence 16S rRNA gene and the gtfB gene sequencing.RESULTS: It was observed genetic similarity among strains isolated from individuals with caries activity; while isolates from individual without caries showed that they are genetically distinct, suggesting a different virulence pattern.CONCLUSION: The present results demonstrated that partial sequencing of the gtfB gene showed to be a potential marker to investigate genetic pattern and virulence of S. mutans, deserving further investigation in order to identify families at risk of caries.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44191814","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}

The aim of this review was to describe the conceptual basis of this measure, including its application, calculation and interpretation.RESULTS: As well as being used to detect the magnitude of the difference between groups, to verify the strength of association between predictor and outcome variables, to calculate sample size and power, ES is also used in meta-analysis. ES formulas can be divided into these categories: I – Difference between groups, II – Strength of association, III – Risk estimation, and IV – Multivariate data. The d value was originally considered small (0.20 > d ≤ 0.49), medium (0.50 > d≤ 0.79) or large (d ≥ 0.80); however, these cut-off limits are not consensual and could be contextualized according to a specific field of knowledge. In general, a larger score implies that a larger difference was detected.CONCLUSION: The ES report, in conjunction with the confidence interval and P value, aims to strengthen interpretation and prevent the misinterpretation of data, and thus leads to clinical decisions being based on scientific evidence studies.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15448/1980-6523.2018.1.29437","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67079676","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}

Observers were trained to use the MCI before analyzing 150 PRs of patients with dual energy X-ray absorptiometry (DXA) examination.RESULTS: The Spearman’s Correlation test showed inverse and weak to moderate correlation between MCI and T-scores, and it varied was according to the observe that performed the evaluation. Observers #2 and #3 (with previous MCI experience) showed the highest agreement with the professor, followed by students #4, #5 and #6.CONCLUSION: Students’ expertise using the MCI increased the agreement with the professor regardless of whether the student was an oral radiology specialist; the MCI was correlated with the DXA in all the observer’s evaluations, which indicates that previous training for the MCI can enable any dentist to apply it in osteoporosis screening.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41382888","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}

The canals were randomly divided into two experimental groups (n=20) according to the preparation instrument analyzed. The preparations were performed by a single operator. The preparation time was controlled, and the values obtained were analyzed. To verify the wear, transportation, and centering ability of the instruments, tomography images were taken before and after instrumentation. The analysis was performed using axial sections previously identified at 2 mm below the tooth apex with the aid of the OnDemand3DTM Dental program. For statistical analysis, Student’s t-test was used, with a significance level of 5%.RESULTS: The time required to prepare root canals was lesser using Prodesign® M instruments than using Flexofile instruments. Regarding tooth wear, no statistical difference was observed. However, Flexofile instruments had a low centralization capacity in root canal preparation, and there is a trend of transport in the mesial direction of the root canal.CONCLUSION: Although no statistical difference was observed between the two instruments, the Prodesign® M instruments had a better cantering ability in the preparation. As well as, the time required to prepare the root canals was inferior when Prodesign® M was used.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15448/1980-6523.2018.1.29468","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47698030","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}
