Teeth trauma may bring about sequences in primary teeth and in developing permanent ones, due to a close anatomic relationship between the primary teeth apexes and the germs of permanent teeth. Current assay forwards teeth sequelae after trauma in primary teeth in a patient without any dental treatment. A ten-year old male made a visit to the UNIVERSO dentistry clinic, without any complaints. Clinical exam revealed color change and prolonged retention of element 51 which caused an eruption deviation in the permanent successor and, consequently, previous crossed bite. Tutors confirmed trauma history at element 51 when five years old, but did not remember the manner and place of accident. They did not mention any dental treatment after the trauma. After radiographic evaluation and exam, exodonty of the deciduous element was performed and the patient was forwarded to orthodental treatment. A fixed inclined plane was executed to relocate the permanent successor. Results show that trauma causes sequelae in the primary tooth and in the permanent successor. Further, lack of treatment and follow-up may have contributed towards an eruption deviation in permanent teeth. Correction of the anterior crossed bite was successful after adequate treatment.","PeriodicalId":30388,"journal":{"name":"Iniciacao Cientifica Cesumar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67827261","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}

Fifty bovine incisors were sectioned in two groups of 4X4 mm standard blocks to obtain 50 specimens in each group (n=50). In fifty blocks, the dentin (D) was analyzed and in the other 50 the enamel (E). Blocks were subjected to bleaching treatment and restored with Single Bond/z250 according to post-bleaching time intervals (0, 7, 14 and 21 days). Twenty-four hours after adhesive/resin cylinders on substrate confection, shear bond strength test (SBS) was performed in an universal test machine. Means in MPa and their respective standard deviations were: E – control: 31.89 (2.39); T0: 19.07 (2.00); T7: 24.97 (4.89); T14: 29.71 (4.89); T21: 40.91 (4.75) and D – control: 18.90 (3.64); T0: 2.22 (0.41); T7: 3.79 (0.75); T14: 5.95 (0.79); T21: 8.40 (0.87). Data were submitted to ANOVA and Tukey (p< 0.05) tests. The bond strength value for the enamel was statistically higher than the dentin, and both were lower than the control group that had similar results after 21 days post-bleaching. In dentin group, the control showed superior bond strength and was statistically different in relation to other times. It was concluded that bleaching had negative influence on adhesion. Therefore it is necessary to wait, at least, 21 days after bleaching to restore the enamel. \u0000 \u0000AVALIACAO IN VITRO DA INFLUENCIA DE DIFERENTES INTERVALOS DE TEMPO POS-CLAREAMENTO COM PEROXIDO DE CARBAMIDA 37% NA ADESAO AO SUBSTRATO DENTAL \u0000 \u0000RESUMO: O objetivo deste estudo foi avaliar a influencia do peroxido de carbamida a 37% sobre a adesao dos substratos dentarios em diferentes intervalos de tempo pos-clareamento. Cinquenta incisivos bovinos foram divididos em dois grupos de blocos padrao 4 x 4 mm para obter 50 especimes de cada grupo (n = 50). Em cinquenta blocos, a dentina (D) foi analisada e nos outros 50 o esmalte (E). Os blocos foram submetidos ao tratamento de clareamento e restaurados com Single Bond/z250 de acordo com os intervalos de tempo pos-clareamento (0, 7, 14 e 21 dias). Apos vinte e quatro horas os corpos de prova preparados com adesivo/resina foram submetidos ao teste de resistencia ao cisalhamento (SBS) em uma maquina universal de ensaio.

Due to anti-cancer treatments, survival children with cancer are prone to have dental anomalies as a delayed effect revealed by full-mouth radiography. However, examiners should have previous training, assessed by concordance tests (Kappa test) for reliable and reproducible results. Calibration is important for examiners to evaluate dental anomalies in patients with cancer so that highly reliable data may be obtained. Forty full-mouth radiographies, twenty of control group and 20 of the experimental group, were randomly selected. Examiners proved to be calibrated when Kappa test rates were between 0.61and 1.0. Intra-examiner calibration featured between least (0.61-0.80) and maximum concordance (0.81 – 1.0) for the two examiners. In the case of inter-examiner calibration, minimum Kappa featured moderate concordance (0.41 – 0.60) during the first stage; whilst a substantial concordance was reached (0.61-0.80) in the second stage, proving standardization of examiners. A careful and detailed calibration is required to evaluate dental anomalies in full-mouth radiographies, enhancing reliable and reproducible information for scientific evidence.","PeriodicalId":30388,"journal":{"name":"Iniciacao Cientifica Cesumar","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67827660","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}

Tideglusib is a GSK-3 inhibitor for the treatment of Alzheimer disease. It has been recently demonstrated that the drug may induce the natural repair of the dental pulp through the activation of stamina cells by regenerating dental material of the damaged area.
