Resumo Introdução O conceito de qualidade de vida é multidimensional, apresenta uma organização complexa e dinâmica dos seus componentes, difere de pessoa para pessoa de acordo com seu ambiente/contexto e mesmo entre duas pessoas inseridas em um contexto similar. Em dezembro de 2019 surgiu na China uma epidemia pelo coronavírus, surgindo a necessidade de mudanças, incluindo isolamento social e ensino a distância. Objetivo Avaliar o impacto do isolamento social e ensino a distância na qualidade de vida dos graduandos da área da saúde da Universidade Federal de Sergipe. Material e método Foi aplicado aos estudantes de graduação da área de saúde da Universidade Federal de Sergipe, no período de janeiro de 2021, o questionário de qualidade de vida, Short-Form Health Survey. O questionário foi aplicado via o sistema online. Resultado Foram aplicados 678 questionários, sendo 672 concordando em participar do estudo. Dos estudantes avaliados, 58% eram do sexo feminino e 50% com idade de 21 a 25 anos. Ao se analisar o questionário, verifica-se que para capacidade funcional os valores variaram de 80 a 89, ou seja, com bom escore de qualidade de vida. Os aspectos emocionais apresentaram os menores escores e 21 a 37,3, sendo o pior resultado encontrado nos estudantes do curso de fonoaudiologia. Não houve diferença estatisticamente significativa entre os diferentes cursos de saúde estudados. Conclusão Verifica-se que o aspecto emocional tem sido o mais afetado entre os estudantes de saúde da Universidade Federal de Sergipe.

Abstract Introduction the Covid-19 pandemic impacted elderly persons with Parkinson’s Disease (PD), influencing their daily activities and quality of life. Objective to evaluate the impact on the oral health in people with Parkinson’s Disease during the Covid-19 isolation. Material and method the present analytical, quantitative, cross-sectional study uses secondary data sources from 115 health records used in a study carried out from August to December in 2020 through telemonitoring. Sociodemographic aspects and self-perception of quality of life were evaluated using the Oral Health Impact Profile (OHIP-14) questionnaire. The variables studied in the association were: sex, age, duration of PD, civil status, Covid-19 diagnosis and the use of dental prostheses. The software Statistica 13.2 and the Chi-square (X2) test with a significance level of p<0.05 were used. Result after analyzing the database, the final sample consisted of 64 health records that responded to the OHIP-14. 61% were male, with a mean age of 66.6 years, 64% were using dental prostheses, and 74% indicated on the OHIP-14 that they had good oral health self-perception. No significant associations were found among the variables: Age, Sex, Civil Status, Covid diagnosis, Duration of illness, Use of dental prostheses and the OHIP-14 (p>0.05). Conclusion it was found that people with Parkinson’s Disease showed a good quality of life, as evaluated using the OHIP-14, and that the Covid-19 isolation did not impact negatively on the oral health.

Abstract Introduction The elderly are among those most affected by Covid-19, and among them are people with Parkinson's disease. Social distancing, due to the coronavirus, has led to new strategies and tools for health monitoring. Objective To describe the oral health conditions, using telemonitoring, of people with Parkinson's disease during the Covid-19 pandemic. Material and method This is an analytical, quantitative, cross-sectional study. The tool used was the video call. The telephone contacts (n=154) were obtained from lists of patients in the Pro-Parkinson Extension Program at the Federal University of Pernambuco. A semi-structured questionnaire was used to gather sociodemographic data and daily oral hygiene practices for teeth and dentures, and whether or not the participant needed dental treatment, during the Covid-19 pandemic. Result The final sample consisted of 64 Parkinsonian patients. Regarding oral health care, the frequency of hygiene in this period was three times a day among 48.44% of participants, with toothbrush and toothpaste being the items most used for this task. More than half of the sample used dental prostheses. The most common oral health problems during this isolation period were pain, mouth sores and the need for tooth extraction. Conclusion Telemonitoring was essential because it was noted that these patients were deficient in their knowledge of basic hygiene practices and in information on oral health, as well as in the care of dental prostheses.

Abstract Introduction Periodontitis control helps to prevent and control diabetes mellitus and understanding of this relationship can lead to changes in health policy. Objective The purpose of this study was to investigate the association between periodontitis, knowledge, and glycemic control. Material and method This is a cross-sectional analytical epidemiological survey with 216 Type 2 diabetic patients, non-smokers, who had current blood screenings with glycated hemoglobin (HbA1c). Result Overall, 93.51% of the patients reported brushing their teeth at least twice a day, 62.5% visited the dentist last year, 81.58% have already undergone treatment for periodontal disease, 43.52% reported having periodontitis and 59.72% had controlled diabetes. No significant (p=0.603) association between HbA1c control and the presence of periodontitis was found. Among the patients with periodontitis, no association between HbA1c control and information on the periodontal disease was found (p=0.996), and know/believe in its relationship with diabetes (p=0.659; p=0.973). Conclusion No relationship between periodontitis and diabetes was found in the sample, as well as in patients with periodontitis, those with knowledge on periodontal disease and knowledge/belief in its relationship with diabetes, which could be justified by the care by a multi-professional health team.

Abstract Introduction Interdisciplinary investigative study of the stomatognathic-cervical complex, necessary to understand the structure and biomechanics of the hyoid bone and cervical spine in Class I and II / 2nd Division participants. Objective To analyze the position of the hyoid bone and the curvature of the cervical spine on lateral radiographs of participants with Class I and II/2nd Division Angle malocclusion. Material and method We evaluated the position of the hyoid bone from its alignment with the corresponding cervical vertebra. The presentation of curvature of the cervical spine was evaluated from the fourth cervical vertebra. Result There was a statistically significant difference in the position of the hyoid bone (p=0.027) between the classes, which was located at C3 in Class I and further down, between C3 and C5, in Class II/2nd Division. The cervical spine showed alterations in both classes, with an increase, rectification, and inversion of the curvature with no statistical difference between them (p=0.533). Conclusion In this study, the hyoid bone showed different positions in the malocclusions studied, however, poor posture of the cervical spine was common in both classes.

Abstract Introduction Endodontically treated teeth are usually affected by extensive structure loss requiring the use of intraradicular posts to provide retention and restoration. Objective An in vitro assessment was performed on the bonding of glass fiber posts to the root dentin. Material and method Ninety (n = 10) single bovine roots were used in a 3 x 3 x 3 factorial study with subdivided plots: post customization varying the presence and type of resin (without customization, conventional resin, and Bulk Fill resin), light-curing device (Valo, Radii-Cal, Rainbow), and root third (cervical, middle, and apical). Result For the customization factor, Tukey’s test (5%) showed the superiority of the Bulk Fill (8.16 MPa) and Z350 (7.40 MPa) groups compared to the control group (4.92 MPa), without differing from each other. All light-curing devices differed, showing the superiority of Valo (9.36 MPa), Radii (6.96 MPa) as an intermediate, and the inferiority of Rainbow (4.17 MPa). The cervical root third (7.81 MPa) was superior, the apical third was inferior (5.80 MPa), and the middle third (6.88 MPa) was an intermediate without differing from the others. Conclusion The customization of glass fiber posts increases the bond strength to the root dentin, regardless of the resin used. There was a compromise in the apical third and when using light-curing devices with lower light intensity.

Resumo Introdução É importante saber se o hipoclorito de sódio (NaOCl) influencia a resistência à fadiga cíclica das limas de níquel-titânio (NiTi). Objetivo Avaliar a influência de NaOCl 2,5% na resistência à fadiga cíclica de dois sistemas de NiTi. Material e método: 40 instrumentos rotatórios – 20 TruNatomy® (TRU, Dentsply Sirona, Maillefer, Ballaigues, Suíça) e 20 Prodesing Logic2® (PDL2, Bassi, Belo Horizonte, Minas Gerais, Brasil) – foram aleatoriamente distribuídos em 4 grupos experimentais (n = 10) imersos em água destilada (H2O) e NaOCl 2,5% em temperatura a 37°C. Foram submetidos a testes de fadiga cíclica mensurando o número de ciclos para fratura (NCF) e análise dessas superfícies pós-teste em microscópio eletrônico por varredura. Para a análise estatística entre os grupos, foi aplicada a análise de variância (ANOVA), complementada com o pós-teste de Tukey. Resultado Houve diferença estatística em todos os grupos (P < 0,05). Os instrumentos PDL2 obtiveram maior resistência à fratura nas condições em H2O e em NaOCl 2,5% comparados aos instrumentos TRU. Na análise de grupos de instrumentos nas soluções de NaOCl e H2O, foi observado que o NaOCl 2,5% diminuiu o NCF. Conclusão A resistência à fadiga cíclica dos instrumentos TRU e PDL2 diminuiu com NaOCl 2,5%. Os instrumentos PDL2 foram mais resistentes à fratura em relação aos instrumentos TRU.

Abstract Introduction Platelet-rich fibrin (PRF) is formed by an autologous blood concentrate, with properties that promote cell proliferation and regenerationof bone, gingival and epithelial tissue. Objective To compare four different procedures for processing as well as obtaining PRF, and analyzing their formation through laboratory techniques. The purpose of the study is to validate a method that produces higher quality PRF for oral surgery use in different branches of dentistry. Material and method The experiment consisted of collecting blood from 12 volunteers, and processing each patient’s sample in 4 different ways. In the following two-stage process analysis, the first, quantitative, step was to analyze the samples' platelet-poor plasma (PPP),with a Neubauer Hemocytometer to count blood components. In the second, qualitative step, the sample’s PRF were analyzed under microscopy using histological slides. Result The statistical analysis of the leukocyte, red blood cell and platelet count did not show any significant distinction when comparing different processes. Histological analysis of the PRF showed fibrin network with platelet aggregation, several leukocytes and presence of red blood cells, with double centrifuged samples presenting more white blood cells than the others. Conclusion: Among the analyzed procedures, the sample centrifuged once at 3000 RPM (1900 G) for 10 min showed the best quality PRF.

Abstract Introduction Temporomandibular disorder (TMD) involves the mastication and temporomandibular articulation muscles. Completely toothless patients with prostheses should be thoroughly assessed since edentulism causes damage that can lead to TMD onset. Objective This study aims to assess the effect of the technical quality of total prostheses (TPs) on TMD occurrence in patients with bimaxillary TPs. Material and method 154 patients responded to a questionnaire to obtain personal data, information regarding prostheses, anamnestic index for TMD, and the prosthesis quality index. Result Of the 154 patients examined, 64 (41.6%) had no TMD, 61 (39.6%) had mild TMD, 23 (14.9%) moderate, and only 6 (3.9%) showed severe TMD. As for the quality of total prosthesis, 78 (50.6%) completely toothless individuals had satisfactory TPs while 76 (49.4) presented unsatisfactory prostheses. Regarding the time using total prosthesis, around 50% of individuals with up to 10 years use presented some degree of TMD and 70% of individuals with over 10 years presented TMD. Conclusion Considering the methodology used and the population studied, we conclude that the quality of the TPs did not influence the incidence of TMD.
