Abstract Introduction Gingivitis is a gingival inflammation which can often be treated with oral hygiene such as brushing, flossing, and an antiseptic mouthwash. Objective The aim of this randomized clinical trial was to clinically evaluate the effectiveness of 0.12% chlorhexidine (CHX) solution as an anti-inflammatory agent and for reducing the presence of plaque and inflammation in young adults. Material and method Thirty patients with gingivitis aged 18 to 30 years with a probing depth ≤ 3 mm and a minimum of 20 teeth in the whole mouth were selected and evaluated at baseline and 30 days after treatment. Periodontal clinical parameters were verified: plaque index (PI), gingival index (GI), Simplified Oral Hygiene Index (OHI-S), Simplified Debris Index (DI-S), and Simplified Calculus Index (CI-S) Patients were then randomly allocated into two groups: CHX Group, received chlorhexidine 0.12% labeled as solution 1, and Placebo Group, received saline solution labeled as solution 2. Both groups were included in a hygiene program and received mouthwash. Result Statistically significant differences between CHX and Placebo groups were observed for the variables PI, GI, DI-S, CI-S, and OHI-S (p<0.05 - Paired T Test) after 30 days. The CHX group presented improved GI compared to Placebo at 30 days. Chlorhexidine 0.12% was efficient in the control of periodontium inflammation. Conclusion It can be concluded that chlorhexidine as a mouthwash is efficient in improving periodontal indices in young adults, but it is still controversial whether age can influence GI and OHI-S.

Abstract Introduction Dental practice professionals encounter several urgency cases, mainly related to endodontic problems. To attend to these, professionals need extensive prior preclinical training, being one of the main difficulties the search for models that simulate dental morphology. Aim To compare the external morphometry of multirooted artificial teeth to literature. Material and method The artificial teeth (Upper First Premolar, Upper First Molar and Lower First Molar) were donated by the manufacturers: Fábrica de Sorrisos (FS) and IM do Brasil LTDA (IM), totaling 30 teeth. The total length of the tooth and root, height and buccal-palatal and mesial-distal dimensions of the crown were measured with a digital pachymeter. The data were placed in a spreadsheet and the statistical analysis was performed [ANOVA or Kruskal-Wallis and then, Dunnett's test (α=5%)]. Result The Upper Molar samples of the company Fábrica de Sorrisos presented all variables within the morphometric patterns described in the literature. The other dental groups presented statistically significant differences, maintaining or not a certain proportionality. Conclusion Of all the dental groups analyzed, the upper molar from the company Fábrica de Sorrisos was the only one that presented all the external morphometric aspects according to literature.
摘要简介牙科专业人员遇到几个紧急病例，主要与牙髓问题有关。为了解决这些问题，专业人员需要广泛的临床前培训，这是寻找模拟牙齿形态模型的主要困难之一。目的将多根人工牙的外形形态学与文献进行比较。人工牙(上第一前磨牙、上第一磨牙和下第一磨牙)由制造商Fábrica de Sorrisos (FS)和IM do Brasil LTDA (IM)捐赠，共30颗牙。用数字测厚仪测量牙、根的总长度、冠的高度、颊腭和中远端尺寸。将数据放入电子表格中，并进行统计分析[方差分析或Kruskal-Wallis，然后进行Dunnett检验(α=5%)]。结果Fábrica de Sorrisos公司的上磨牙样品呈现了文献中描述的形态测量模式中的所有变量。其他牙组差异有统计学意义，保持或不保持一定的比例关系。结论在分析的所有牙组中，根据文献，只有Fábrica de Sorrisos公司的上磨牙具有所有外部形态计量学方面的特征。

Abstract Introduction Obtaining the result expected during tooth bleaching requires a correct diagnosis of the type of staining presented. The causes of tooth staining differ depending on the etiological factor. Objective To assess the color change caused by the immersion of bovine teeth in coffee solution during at-home tooth bleaching using a 16% carbamide peroxide gel. Material and method Thirty-three sound bovine teeth were assigned to three groups of eleven teeth each: 1 – Teeth bleached (TB) four hours per day for 21 days; 2 – TB four hours per day for 21 days and immersed in coffee solution immediately after tooth bleaching; 3 – TB four hours per day for 21 days and immersed in coffee solution four hours after the end of tooth bleaching. Immersed in coffee was performed for 15 minutes and tooth color was assessed before the start of the bleaching procedure and after 21 days with an intraoral spectrophotometer. Test Shapiro-Wilk was used to assess homoscedasticity and data were submitted to one-factor Analysis of Variance (ANOVA) and Tukey’s test (p <0.05). Result The color change observed in group 1 (5.76 ± 2.74)A was not statistically different from group 2 (8.83 ±5.11)A, which was immersed in coffee solution immediately after tooth bleaching, and from group 3, which was immersed in coffee solution four hours after tooth bleaching (8.20 ±3.71)A. Conclusion Coffee did not interfere with the tooth bleaching results, regardless of the time after the procedure. Hence, diet restrictions are not necessary during tooth bleaching.

Resumo Introdução A dor dentária, ou odontalgia, é definida como uma dor de origem orofacial, que ocorre como consequência dos problemas que afetam os dentes e as estruturas de suporte. Objetivo O objetivo do presente estudo foi analisar os fatores associados à dor dentária em indivíduos com 18 anos ou mais de idade, no município de Rio Grande-RS, ao sul do Brasil. Material e método Estudo transversal de base populacional. Foram entrevistados, no domicílio, 1.099 indivíduos, por meio de um questionário com questões fechadas. Foram obtidas informações demográficas, socioeconômicas e relativas a hábitos e comportamentos de saúde geral e bucal. O relato de dor dentária nos seis meses anteriores ao inquérito foi o desfecho do estudo. As análises foram baseadas em regressão de Poisson. Resultado A prevalência de dor dentária foi de 18,0% (IC95% 15,6; 20,4). Ao se analisar por faixa etária, a prevalência de dor dentária foi de 23,9% (IC95% 20,3; 27,4), 14,0% (IC95% 10,6; 17,5) e 10,4% (IC95% 5,8; 15,0), considerando a população adulta de 20 a 39 anos e de 40 a 59 anos, e a população idosa, acima de 60 anos, respectivamente. Maiores prevalências de dor origem dentária foram em indivíduos solteiros (RP=1,50; IC95% 1,11; 2,03), com menor escolaridade (menos de oito anos de estudo) (RP=1,62; IC95% 1,16; 2,27) e com o hábito de ranger os dentes (RP=1,67; IC95% 1,18; 2,38). Já os idosos apresentaram menores prevalências de dor origem dentária, quando comparados aos indivíduos adultos (RP=0,50; IC95% 0,32; 0,80). Conclusão Maior atenção deve ser dada aos solteiros, menos escolarizados, que rangem os dentes, e aos adultos jovens.

Resumo Introdução O clareamento dental é um procedimento amplamente realizado, levando a uma procura de informação pelos pacientes, sendo que uma dessas fontes são os vídeos do YouTube. Objetivo: Avaliar a qualidade das informações contidas nos vídeos do YouTube sobre clareamento dental no Brasil. Material e método Uma busca no YouTube foi realizada com a frase “clareamento dental”. Os primeiros 100 vídeos foram selecionados e visualizados na íntegra por dois examinadores, e parâmetros gerais foram registrados. Para avaliar a qualidade das informações, duas análises foram realizadas, avaliando a utilidade e a confiabilidade das informações. O teste de Mann-Whitney foi utilizado para avaliar e comparar a qualidade das informações. Resultado Dos 100 vídeos selecionados, 22 foram excluídos por não se adequarem aos critérios de seleção, restando 78 vídeos. Sobre a utilidade dos vídeos, 65,4% foram classificados como não úteis, 26,9% pouco úteis, 6,4% moderadamente úteis e apenas 1,3% muito útil. Sobre a confiabilidade dos vídeos, 94% não utilizaram fontes confiáveis de informação e 69% das informações não se apresentaram equilibradas e imparciais. Por outro lado, 60% dos vídeos exibiram informações claras e objetivas. Conclusão Atualmente, o YouTube não é uma fonte adequada de informações para pacientes sobre clareamento dental no Brasil. Sobre a qualidade dos vídeos, a maioria não se apresentou como satisfatória para os critérios de confiabilidade e utilidade. Os dentistas são a melhor fonte de conteúdo para clareamento dental. Entretanto os vídeos mais populares são de leigos e normalmente abordam receitas caseiras de clareamento dental.

Abstract Introduction There is no consensus about the immediate and latte follow-up effects of maxillary protraction in cleft lip and palate patients. Objective To evaluate the stability of Class III early treatment in cleft lip and palate patients through maxillary expansion and protraction. Material and method The sample consists in three lateral cephalometric radiographs of 28 patients (mean pre-treatment age of 6.7±1.8 years) who presented cleft lip and palate and were treated with maxillary expansion and Petit facial mask. The angular (SNA, SNB, ANB, SN.GoGn, FMA, Z Angle) and linear (overjet, Co-A, Co-Gn, Nperp-A, Nperp-Pg, AO-BO) cephalometric measures were evaluated through the Dolphin® software, in three moments: T0 (initial), T1 (after treatment), and T2 (follow-up). Data were submitted to the analysis of variance (ANOVA) and Tukey-Kramer test. The correlation between cephalometric measures and patient’s age was determined by Pearson’s chi-squared test. Result The SNA, ANB, and AO-BO measures increased considerably (p<0.05), and they did not present any differences compared to the initial ones after the follow-up time. The overjet measure increased (p<0.05) after treatment and, even with its decrease at the follow-up time, it was still higher than at the beginning (p<0.05). The Z angle showed improvement with treatment and remained stable at the follow-up time. Conclusion After treatment (maxillary expansion associated with protraction), there was a skeletal pattern improvement. During the follow-up period, those alterations decreased to a measure close to the beginning. There was an improvement in the dental pattern and facial profile that continued in the follow-up period.

Introduction: The sterilization and disinfection procedures should be adapted to the chemical profile of the metal alloys present in the instruments. Objective: This study aimed to perform a micrographic assessment on the surface characteristics of the widia of orthodontic pliers with two alloy compositions subjected to the action of 0.2% peracetic acid and intensive use. Material and method: Twenty distal cutting pliers were divided into two groups (n=10) according to widia composition (%wt): W185% to 87% of tungsten carbide (TC) and other components in the proportion of 13% to 15% and W2 – 87.5% to 88.5% of tungsten carbide and 11.5% to 12.5% for other components. All the pliers were assessed in a stereoscopic magnifying glass (32x) after three treatments: before use (T0); after cutting 100 segments of rectangular stainless-steel wires – intensive use (T1); and after 100 sterilization cycles in 0.2% peracetic acid and intensive use (T2). The cutting sites of all pliers were standardized. Widia regions were defined by line “A” representing T1 and line “B” representing T2. A frequency distribution table and Fisher’s exact test (α=0.05) was performed. We assessed two widia from each composition and treatment in SEM and energy-dispersive X-ray spectroscopy (EDS/SEM). Result: The results showed that W1 pliers presented Micrographic evaluation of different... Rev Odontol UNESP. 2020;49:e20200021.

There were no differences between both pliers after intensive use (p=1.000). Conclusion: The SEM images and EDS analyses showed changes in widia surfaces after the different treatments. Widia composition affected the resistance of the orthodontic pliers after sterilization cycles with 0.2% peracetic acid and intensive use. Descriptors: Sterilization; orthodontics; peracetic acid.

Abstract Introduction Although many studies are being carried out with sleep bruxism, the literature points to a lack of studies with methodological quality in children. Objective To evaluate the behavioral and clinical aspects associated with probable sleep bruxism in early childhood. Material and method A cross-sectional observational study carried out with 371 children between 4 and 6 years of age. Parents answered a questionnaire with aspects related to their children's sleep behavior. Among the clinical characteristics, the presence of lip sealing, clicking, teeth marks on the jugal mucosa, and the side of the tongue was evaluated. Tooth wear was assessed using the BEWE index criteria. Simple logistic regression models were adjusted for each independent variable, estimating the gross odds ratios with the respective 95% confidence intervals. Variables with P <0.20 in the individual analyzes were adjusted in a multiple logistic regression model, with those with P ≤ 0.05 remaining in the model. Result 42.4% of parents reported that their children gritted their teeth while sleeping. Children who showed wear on their teeth were 1.53 times more likely to grind their teeth. There was no significant association with the other variables analyzed (P > 0.05). Conclusion Behavioral aspects were not associated with probable sleep bruxism. Among the clinical characteristics evaluated, tooth wear showed an association, which may indicate the probable bruxism of sleep in early childhood.

Abstract Introduction Considering the increased search for esthetic procedures, questions emerge about the maintenance and regression of color, especially regarding the need to restrict dark foods during bleaching procedures or their influence on the stability and effectiveness of the treatment. Objective To assess the influence of staining agents on tooth enamel during immediate bleaching treatment with 35% hydrogen peroxide. Material and method Sixty bovine teeth were divided into six groups (G) (n=10): G1: distilled water (control); G2: coffee; G3: cola soft drink; G4: wine; G5: mate tea; and G6: industrialized açaí. The samples were subjected to immediate bleaching using 35% hydrogen peroxide for 21 days (three applications of 15 minutes per session, every seven days) and pigment immersion between each session for 15 minutes. The color was assessed before starting bleaching and after 21 days, using a spectrophotometer. The data obtained were subjected to one-way ANOVA and heteroscedasticity analysis by the Welch and Brown-Forsythe tests. The Tamhane test was used for group comparison. Result The color change was visible to the naked eye, considering the mean ΔE in all groups tested was higher than 3.7. However, there was no statistical difference between the control group and the groups assessed. Conclusion The contact of staining agents on bovine tooth enamel did not affect the final result of the immediate tooth bleaching.
