OBJECTIVE: Dental aesthetics is one of the areas of dentistry that has most advanced in terms of procedures, techniques and materials. 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.

OBJECTIVE: Unerupted tooth, also called impacted tooth by some authors, is a dental organ that, even when fully developed did not erupt at the regular time, lying inside the bone completely surrounded by bone tissue or bone and mucosal tissue. The unerupted canines study is very important in dentistry, since successful results depend on early diagnosis for proper treatment management, however, despite the importance of this issue, few studies were found in the literature.CASE DESCRPTION: This paper reported a clinical case of a 14-year-old female patient who had four canines in the mentonian region of the mandible surrounded by a dentigerous cyst. The patient underwent a surgical procedure under general anesthesia for the teeth and dentigerous cyst removal.

OBJECTIVE: To investigate the pulpal response to direct pulp capping in healthy human teeth with Portland cement (PC) as against mineral trioxide aggregate (MTA) as control.METHODS: Forty healthy human third molars indicated for extraction were randomly divided into two groups: PC and MTA. The teeth had iatrogenic pulp exposed and direct pulp capping with PC or MTA. After 1, 7, 14 and 21 days, the teeth were extracted and prepared for histological examination and bacterial detection. The Mann-Whitney test was applied for statistical analysis (p < 0.05).RESULTS: The MTA presented higher capacity to form of dentin bridges at 14- and 21-day intervals (p < 0.05). However, no significant statistical difference was found between the groups at all evaluated intervals (p > 0.05) for the response variables of inflammatory cells, soft tissue organization and bacterial staining.CONCLUSION: The PC has a biocompatibility equivalent to the MTA but with a lower capacity to form of dentin bridges. Therefore, MTA should be the material of choice for direct pulp capping.

OBJECTIVE: Caries is a multifactorial infectious disease and the main etiological agent is the bacteria Streptococcus mutans due to its virulence factors, which enable the adherence to dental enamel and favours the formation of dental biofilm through the production of extracellular polysaccharides. 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.

OBJECTIVE: Effect size (ES) is the statistical measure which quantifies the strength of a phenomenon and is commonly applied to observational and interventional studies. 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.

OBJECTIVE: Survival rates of mandibular overdentures on two implants retained by bar-clip system with immediate loading and the factors related to fractures was analyzed.METHODS: Twenty-three subjects were followed for 32 months. Fracture occurrence was the outcome variable, while the thickness of denture base, maxillomandibular space and masticatory efficiency comprised the independent variables.RESULTS: The survival rate was 49.5%, with 34.7% of fractures. There was no association between the independent variables and fractures.CONCLUSION: So, the risk of mandibular overdenture fractures with immediate loading is high. Furthermore, masticatory efficiency, thickness of the denture base and maxillomandibular space did not influence the incidence of fractures.

OBJECTIVE: Mandibular Cortical Index (MCI) is useful in osteoporosis screening. This study aim was to verify the impact of different expertise levels in the observers’ performances of MCI evaluation in panoramic radiographs (PR).METHODS: Six participants were recruited: one Oral Radiology professor with previous experience (#1), one master’s degree student and radiologist with previous experience (#2), one PhD student and non-radiologist with previous experience (#3), one PhD student and radiologist with no prior experience (#4) and two master’s degree students with no prior experience (#5 and #6). 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.

OBJECTIVE: This in vitro study aimed to evaluate preparation time, wear, transportation, and centering ability of two manual instruments, namely Flexofile and Prodesign® M, in curved root canal preparation.METHODS: Forty mesiobuccal and mesiolingual canals of the first or second lower molars were used, with standard length, degree, and radius of curvature among all samples. 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.

OBJECTIVE: This study aimed at investigating the relationships between health and work-related musculoskeletal disorders (WMSDs) in dentists, and the relationship with socio-demographic, work and health variables.METHODS: We conducted a cross-sectional study of 204 dentists who work in public clinics in the state of São Paulo, Brazil. We used a self-administered survey that included questions on sociodemographic and health aspects, work-related factors, and the Nordic questionnaire.RESULTS: WMSDs were often reported in the neck, shoulder, lower back, and hand/wrists. Logistic regression analysis revealed that there was a correlation between reports of WMSD in the neck and age (OR = 9.48) and health problems (OR = 6.71). Moreover, strong associations were found between MSDs in the shoulders, gender (OR = 5.88) and breaks between appointments (OR = 4.17).CONCLUSION: We concluded that the health problems diagnosed, work-related activities and gender contributed to musculoskeletal disorders in dentists in this clinic.

Logistic regression analysis revealed that there was a correlation between reports of WMSD in the neck and age (OR = 9.48) and health problems (OR = 6.71). Moreover, strong associations were found between MSDs in the shoulders, gender (OR = 5.88) and breaks between appointments (OR = 4.17).CONCLUSION: We concluded that the health problems diagnosed, work-related activities and gender contributed to musculoskeletal disorders in dentists in this clinic.","PeriodicalId":38878,"journal":{"name":"Revista Odonto Ciencia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.15448/1980-6523.2018.1.29699","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48919200","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}
