Abstract Introduction Circulatory system diseases are one of the leading causes of death. Periodontal health is a component of oral and general health that contributes to quality of life. Objective To analyze periodontal conditions and quality of life in patients with circulatory diseases. Material and method Cross-sectional study, with patients with circulatory diseases (n=125). The clinical periodontal examination was performed considering: biofilm, bleeding on probing, suppuration, probing depth, gingival recession, and clinical attachment level. Quality of life was assessed with the Medical Outcomes Study 36 – Item Short-Form Health Survey (SF-36) and Oral Health Impact Profile – short form (OHIP-14). Data were analyzed with parametric and nonparametric tests (α=5%). Result Elderly and men had a greater severity of periodontal disease. The Elderly had lower values in the domains of "Functional capacity" and "Physical aspects" (SF-36). The domain "Pain" had lower values in subjects with health/gingivitis. OHIP-14 did not show differences in the comparisons. There was no correlation between quality of life and the severity of periodontal disease. Conclusion Among patients with circulatory diseases, the elderly and men had greater severity of periodontal disease. The elderly had a poorer quality of life (functional capacity and physical aspects). There was no correlation between the severity of periodontal disease and quality of life.

Resumo Introdução A periodontite é uma doença infecto-inflamatória, resultante da disbiose microbiana e da resposta do hospedeiro, que leva à destruição dos tecidos de suporte dentário, inclusive das fibras colágenas periodontais, podendo culminar na perda do elemento dental. Objetivo Avaliar o comportamento das fibras colágenas periodontais durante a progressão da periodontite experimental induzida em ratos. Material e método Doze ratos Wistar foram distribuídos nos grupos: Controle (C), Periodontite Experimental 14-dias (PE-14d), Periodontite Experimental 21-dias (PE-21d) e Periodontite Experimental 42-dias (PE-42d). No dia 0, os animais do grupo C foram eutanasiados. Neste mesmo dia, os animais remanescentes foram submetidos à instalação de uma ligadura de algodão ao redor do primeiro molar inferior esquerdo para indução da periodontite experimental. Tais animais foram eutanasiados aos 14 (PE-14d), 21 (PE-21d) e 42 (PE-42d) dias após a instalação da ligadura. Executou-se o processamento histológico das hemimandíbulas e as secções foram submetidas à reação histoquímica pelo vermelho picro-sirius. A análise qualitativa descritiva foi realizada sob microscopia de luz polarizada, na região de furca dental, evidenciando as fibras do ligamento periodontal. Resultado O grupo C exibiu feixes espessos e orientados de fibras colágenas maduras, condizentes com aspecto de normalidade. Os grupos com periodontite experimental exibiram desestruturação tecidual severa, com fibras colágenas imaturas e de menor espessura, sendo tais condições mais exacerbadas nos grupos PE-14d e PE-21d. Conclusão As fases iniciais da periodontite apresentam caráter agudo e, portanto, resultam na rápida destruição dos tecidos periodontais de suporte, prejudicando potencialmente a fibrilogênese e a reestruturação do colágeno no ligamento periodontal.

Abstract Introduction with the technological advance in dentistry, light-polymerized three-dimensional (3D) printing resins had become an alternative for the manufacture of occlusal splint splints. Objective the present study aimed to analyze the flexural strength of a resin for 3D printing compared to conventional acrylic resins (chemically activated and thermally activated), under the influence of thermocycling. Material and method 60 specimens were made, which were distributed in six experimental groups (n = 10), according to the resin employed (chemically activated acrylic resin, thermally activated acrylic resin and 3D printing resin) and the treatment received (control and thermocycling). The specimens were submitted to flexural strength by the three-point flexural test. Result data analysis showed that the material factor (<0.0001) and the thermocycling factor (p = 0.0096) influenced flexural strength, however, the interaction between the two factors did not (p = 0.9728). Conclusion it was concluded that 3D printing resins presented the lowest flexural resistance to acrylic resins, especially when submitted to thermocycling.

Abstract Introduction mass contamination by the new coronavirus caused enough damage for the pandemic to extend indefinitely Objective the objective of this study was to analyze the emotional factors acquired by students from a dentistry course during the COVID-19 pandemic period and the influences related to the resumption of face-to-face activities. Material and method it is an observational, cross-sectional and analytical research conducted at a public university in the state of Pará, Brazil. A research questionnaire, prepared by the authors and validated by the ethics committee of the Federal University of Pará, was applied to the academic community for a period of three months (November 2020 to January 2021). The analysis was performed using the Excel program, Kappa statistics and the Chi-squared test, whose results were presented as frequency and percentage. Result a total of 188 dental students participated in the research. The findings proved to be in accordance with the hypothesis generated by the researchers, about 19.2% had emotional crises and 3.7% increase in the lockdown period. As for the expectations for care services, there was an increase in the oppressive state of psychic crises (anxiety, stress, anger, fear), considered influential in the cognition of behavioral traits during post-pandemic care. Conclusion the study identified that the emotional changes acquired in the pandemic outbreak had a negative impact on student performance; however, depressive symptoms were expressed in graduating students.

Abstract Introduction fluoride toothpaste is widely used by the population. Objective dentifrices with a high concentration of sodium fluoride and the presence of tricalcium phosphate were developed, providing additional protection to patients vulnerable to the development of caries. This study aimed to evaluate the influence of different dentifrices on the surface and internal hardness and enamel wear after artificial caries, pH cycling, and toothbrushing. Material and method enamel blocks (4x4 mm) were obtained from 20 bovine teeth. The specimens were submitted to artificial caries lesion and then to pH cycling and brushing according to the dentifrice: Colgate Total 12 and Clinpro + Tricalcium Phosphate. Result after this period, they were submitted to analysis of superficial and internal hardness and profilometry. Scanning Electron Microscopy (SEM) was performed. The data obtained were evaluated by one-way Analysis of Variance (ANOVA) to evaluate the mineral recovery and profilometry, and two-way repeated measures ANOVA to evaluate the superficial and internal hardness. Conclusion analyzing the surface hardness, after caries induction, there was a significant reduction in hardness that was partially recovered regardless of the dentifrice used. For internal hardness, Clinpro obtained lower values on the control side and up to 90 micrometers on the test side. As for profilometry, Colgate Total 12 showed greater wear when compared to Clinpro. It was concluded that Clinpro promoted lower internal hardness, however, Colgate Total 12 resulted in greater surface wear of tooth enamel.

Abstract Introduction Interdisciplinary investigative study of the stomatognathic-cervical complex, necessary to understand the structure and biomechanics of this system in Angle Class I and II / 2nd Division participants. Objective To evaluate alignment and position of cranial cervical structures on radiographs and their functional relationship with the stomatognathic system. Material and method Trans Oral and Profile radiographs were submitted to biomechanical analysis, considered the linear and angular measurement of Atlas and Axis through the application included in the radiogram software. Result We observed a significant difference in the angular measurements of vertical alignment between the Skull, Axis, and the Mandible (p = <0.001), and in the left joint between the Atlas and the Axis (AE: p = 0.011; SEA: p = 0.042). Among the linear measures of the distances between the Atlas and the Axis, the AOD distance presented statistics quite close to the level of significance (p = 0.0502), but above. There was no statistically significant difference in the other measures. Conclusion In this study, the alignment between the Atlas and Axis cervical vertebrae and the mandible and angles of the atlanto-occipital joints are altered in Class II / 2nd Division participants. There is no difference in the size and distance of the Atlas and the Axis between the Classes.

Abstract Introduction The coronal opening is essential, during endodontic treatment, for direct access to the root canals. Usually, in the anterior teeth, endodontic access is achieved on the palatal/lingual surface, more specifically in the cingulum region. However, the lack of observation for dental positioning can lead to some accidents and complications, such as buccal perforations, causing esthetic damage and compromising the treatment. Objective To evaluate the applicability of a new approach for performing coronal opening in anterior teeth, regarding the wear caused on the tooth crown, and to evaluate the ease of performing the new technique to minimize the risk of perforation. Material and method Ten students (n=10) from the Improvement in Endodontics program participated in the present study. Twenty artificial teeth were used, which were upper, central incisors. Each participant performed two coronal openings. First, with no guidance (Group A - Conventional Technique) and afterward, a new opening, but with guidance with the spherical diamond tip placed parallel to the long axis of the tooth (Group B - Modified Technique). Result The results showed that 90% of the participants considered the Modified Technique as having lower risk of accidents, as well as being easier for locating the pulp chamber. There was a statistical difference both in the measurement of the total area of wear and in the width, while there was no statistical difference in the height. Conclusion Preliminary data collected with the survey were satisfactory for the Modified Technique. Statistically, it showed a favorable difference in relation to the area of wear and the width. However, in height there was no statistical difference.

Abstract Introduction root canal treatment is a challenging procedure often first encountered by undergraduate dental students, leading to various difficulties and mistakes. Objective this study aimed to identify the specific difficulties encountered by undergraduate dental students during root canal treatment and the frequency of mistakes they committed in relation to these difficulties. Material and method this study employed a cross-sectional survey design. A cohort of 60 third-year students completed a self-administered questionnaire consisting of 27 questions addressing various aspects of endodontic treatment and 11 key areas of root canal procedures. The response options for each question were based on a 4-point Likert scale. Data analysis was performed using Python programming language and heatmaps were created using the seaborn library to better understand the distribution of the data. Result students encounter challenges in developing tactile sensation, accessory cone placement, and accurately reaching the apex during canal location. Dental schools should focus on improving students' tactile skills and methods to reach the apex to enhance the effectiveness of root canal treatment education. In contrast, students reported fewer mistakes in rubber dam application and safety measures during treatment. Dental educators should emphasize proper instrument use and safety precautions during root canal treatment. Interestingly, students did not perceive these areas as problematic despite committing mistakes. Conclusion this study provides valuable insights into the challenges and mistakes encountered by undergraduate dental students during root canal treatment. Dental educators should address these issues to improve students' skills and techniques and provide optimal patient care.

Abstract Introduction Dentin adhesives provide union between the dental substrate and composite resin, but this union can be influenced by the cleaning agent. Objective Evaluate the use of ozonated water as a cavity cleaning solution. Material and method 40 bovine dental crowns were selected, divided into four groups: AD (dentin cleaning with distilled water) and AO (dentin cleaning with ozonized distilled water). Each group was divided into two storage periods (24h and 30 days) kept at 37 °C. The selected universal system adhesive was employed according to the manufacturer's instructions and light cured for 20 seconds. At that time, three cylinders were made (Tygon matrix with an internal diameter of 2 mm and a height of 2 mm) of composite resin in the crowns in the cervical, médium, and incisal regions and light cured for 30 seconds. After storage, the bonding strength was tested by micro-shear, and fracture type analysis was performed. The data were submitted to statistical analysis using the Shapiro-Wilk test with a significance level of 95%, ANOVA, and Turkey. Result There was a statistically significant difference between the bond strength values, only in the intergroup analysis for the time of 24 hours, between the middle third of the groups (LDAO24 = 2.70 (± 2.39); LDAO30 = 3.82 (± 2.31)). The predominant fracture type for both groups was an adhesive fracture, except in the medium and incisal thirds of the AD, which was a cohesive dentin fracture. Conclusion The utilization of ozone did not change the bond strength adhesive.

Resumo Introdução a recomendação mais atual é de que a higiene bucal deve ser iniciada após a erupção do primeiro dente. Porém, há divergência de opiniões a respeito da necessidade ou não da higiene bucal do bebê desdentado. Objetivo avaliar as práticas maternas de higienização bucal dos bebês menores de 6 meses de idade. Material e método foi aplicado um formulário digital contendo quatro questões sobre informações sociodemográficas e quatro questões específicas. Foi realizada análise estatística descritiva, e os resultados foram comparados estatisticamente entre as crianças que receberam e não receberam higiene bucal antes dos 6 meses de idade. Resultado pode-se observar que a idade, a escolaridade e a renda familiar das mães que realizavam higiene bucal de seus filhos antes da erupção do primeiro dente foram maiores do que das mães que não realizavam esse tipo de higiene. A idade das crianças, a idade de erupção do primeiro dente, o recebimento de orientações profissionais e o tipo de aleitamento não diferiram entre os grupos. Conclusão ainda há uma grande parcela de mães que realiza higiene bucal dos bebês edêntulos.
