Progesterone receptors in extratesticular ducts of the Amazonian stingray Potamotrygon wallacei: A potential role in sperm maturation and aggregate formation.

In cururu stingray (Potamotrygon wallacei Carvalho, Rosa and Araújo 2016) males, plasma progesterone (P4) levels appear to be associated with spermiation events. However, the specific contribution of P4 in sperm maturation via extratesticular ducts in this stingray species is unknown. With the aim of filling this knowledge gap, this study examined the morphology and the presence of progesterone receptors (PR) in the ducts, and analyzed the relationship of progesterone (P4) with sperm maturation and formation of aggregates. Morphological analysis showed that a columnar pseudostratified epithelium with stereocilia lined all the attached ducts. In active males, the secretory cells of the epididymis and the Leydig glands presented PR; however, these receptors were not found in the distal region of the epididymis (essential for nurturing and capacitation events) of regressing males. In the seminal vesicles of active males, the spermatozoa are parallelly aligned and embedded in a matrix to form the spermatozeugmata. The matrixes are formed by proteins secreted by the ducts and Sertoli cell cytoplasts. These structures presented PR, which suggests that P4 engages in sperm metabolism during storage. Our findings allude to the potential role of P4 in regulating the development and function of the attached ducts in different reproductive phases. Furthermore, P4 seems to be an essential component for regulating sperm progress, protein secretion, aggregate formation, and maintenance of sperm during storage in this freshwater stingray.

Characterization of education, technical practices and attitudes of Portuguese pharmacy technicians towards manipulation of cytotoxic drugs.

Pharmacy professionals that manipulate cytotoxic drugs need to undergo educational programs, adopt the most convenient practices, and use appropriate equipment to avoid, as far as possible, occupational exposure to cytotoxic drugs. The main goal of this work is to characterize the education, technical practices, and attitudes towards cytotoxic drugs, of Portuguese pharmacy technicians. A questionnaire comprising eleven questions deemed pertinent was elaborated and subsequently validated by a pilot test. The anonymous, web-based survey was conducted between December 2022 and January 2023, by graduated pharmacy technicians that had manipulated cytotoxic drugs between 2017 and 2022. A total of 77 pharmacy technicians responded to the survey. Although sixty-six pharmacy technicians (86%) had been trained before beginning to manipulate cytotoxic drugs, the promotion of regular post-admission training by the institutions is sparse - only assumed by 53% of the pharmacy technicians (n = 41). All participants reported using gloves and gown during manipulation and the use of double gloves was common (99%; n = 76). Compliances with the recommended limit time for uninterrupted manipulation activity (82%; n = 63) and systematic double-checking (86%; n = 66) were high, but the regular use of sterile gauze around syringe connection sites 58% (n = 45), was less frequent. None of the surveyed pharmacy technicians used closed-system transfer devices (CSTD) and 41 (53%) of those who used spikes did not thoughtfully use these devices. The implementation of regular training programs in manipulating cytotoxic drugs should be fostered, to promote the more judicious use of engineering controls and transversal adoption of the safest technical practices.

Sexual selection and the evolution of sperm morphology in sharks.

Post-copulatory sexual selection, and sperm competition in particular, is a powerful selective force shaping the evolution of sperm morphology. Although mounting evidence suggests that post-copulatory sexual selection influences the evolution of sperm morphology among species, recent evidence also suggests that sperm competition influences variation in sperm morphology at the intraspecific level. However, contradictory empirical results and limited taxonomic scope have led to difficulty in assessing the generality of sperm morphological responses to variation in the strength of sperm competition. Here, we use phylogenetically controlled analyses to explore the effects of sperm competition on sperm morphology and variance in sharks, a basal vertebrate group characterized by wide variation in rates of multiple mating by females, and consequently sperm competition risk. Our analyses reveal that shark species experiencing greater levels of sperm competition produce sperm with longer flagella and that sperm flagellum length is less variable in species under higher sperm competition risk. In contrast, neither the length of the sperm head and midpiece nor variation in sperm head and midpiece length was associated with sperm competition risk. Our findings demonstrate that selection influences both the inter- and intraspecific variation in sperm morphology and suggest that the flagellum is an important target of sexual selection in sharks. These findings provide important insight into patterns of selection on the ejaculate in a basal vertebrate lineage.

Bacterial Profile and Radiographic Analysis Around Osseointegrated Implants With Morse Taper and External Hexagon Connections: Split-Mouth Model.

The aim of this clinical study was to evaluate bacterial colonization, marginal bone loss, and optical alveolar density in implants with Morse taper (MT) and external hexagon (EH) connections. Thirty-five implants were installed in 7 patients (mean age: 65.8 ± 6.7 years). Implants were divided into 2 groups, according to platform design: G1 - MT, installed 2mm infra-osseous and G2 - EH, positioned according to Branemark protocol. Patients were evaluated at baseline (T0), 21 days (T1), 3 months (T2), 6 months (T3), and 12 months (T4) after installations. Bone loss and alveolar density were evaluated by standardized periapical radiographs and bacterial profile with checkerboard DNA-DNA hybridization. Statistical analyses were performed using SPSS 23.0. To present the results, boxplots and a line graph of mean were used. P-values ≤ .05 were statistically significant. After 3 months, alveolar bone loss was significantly higher in the G2 (T2-T0: P = .006; T3-T0: P = .003; and T4-T0: P = .005). No significant differences between G1 and G2 groups were observed for optical alveolar density. Microbiological analysis showed similar profiles between studied groups; however, there were significantly higher counts of Tannerella forsythia (P = .048), Campylobacter showae (P = .038), and Actinomyces naeslundii (P = .027) in G1 after 12 months. Based on the results of this study, it can be concluded that there was less peri-implant bone loss in MT compared to EH connections, but microbiological profile did not seem to influence bone changes.

Facial Pain: RCT between Conventional Treatment and Fascial Manipulation® for Temporomandibular Disorders.

Background: To investigate the effectiveness of a specific manual therapy, Fascial Manipulation® (FM), in comparison with conventional treatments in temporomandibular disorders (TMD) patients using a two-arm randomized controlled trial. Methods: The study consisted of 28 patients that were divided in two groups (Group 1: Fascial Manipulation® vs. Group 2: conventional TMD treatment). The Verbal Rating Scale (VRS), RDC/TMD, electromyography (EMG) and Pression/Pain Evaluation on Masseter and Temporalis Muscle were assessed with different times. Results: In both groups, the improvement in pain was evident on the VRS scale (p < 0.0001) and pain-free opening (p < 0.001). In Group 1, the recovery of the function was faster; maximum unassisted opening T0 vs. T1 (p = 0.001). Conclusions: FM® can be used as an effective method for facial pain, being a rapid, safe and cost-effective approach to reduce pain, gain function and mouth opening that can be used prior to occlusion stabilization appliances.

A case report of a sub-clinical necrotising lower limb infection secondary to pelvic anastomotic leak and chronic corticosteroid use.

Anabolic steroids have attracted attention from the media with regard to misuse, but overuse of medically prescribed steroids also has a propensity to cause harm. Gluteal necrotising soft tissue infections are an uncommon presentation for plastic surgeons, and therefore, abdominal sources may be overlooked. We report a rare case of a 57-year-old male who presented with a necrotising lower limb infection on a background of long-term corticosteroid overuse and recurrent pelvic anastomotic leaks.

Bilateral Low-Dose Computed Tomography Assessment for Post-Operative Rotational Malalignment After Intramedullary Nailing for Tibial Shaft Fractures: Reliability of a Practical Imaging Technique.

INTRODUCTION: The purpose of this study is to evaluate the intra- and inter-observer reliability of low-dose protocolled bilateral postoperative Computed Tomography (CT)-assessment of rotational malalignment after intramedullary nailing (IMN) of tibial shaft fractures. MATERIALS AND METHODS: 156 patients were prospectively included with tibial shaft fractures that were treated with IMN in a Level-I Trauma Centre. All patients underwent post-operative bilateral low-dose CT-assessment (effective dose of 0.03784 - 0.05768 mGy) as per hospital protocol. Four observers performed the validated reproducible measurements of tibial torsion in degrees, based on standardized techniques. The Intra-Class Coefficient (ICC) was calculated to evaluate intra- and inter-observer reliability. The intra- and inter-observer reliability was categorized according to Landis and Koch. RESULTS: Intra-observer reliability for quantification of rotational malalignment on post-operative CT after IMN of tibial shaft fractures was excellent with 0.95 (95% CI = 0.92-0.97). The overall inter-observer reliability was 0.90 (95% CI = 0.87-0.92), also excellent according Landis and Koch. CONCLUSION: Firstly, bilateral post-operative low-dose -similar radiation exposure as plain chest radiographs- CT assessment of tibial rotational alignment is a reliable diagnostic imaging modality to assess rotational malalignment in patients following IMN of tibial shaft fractures and it allows for early revision surgery. Secondly, it may contribute to our understanding of the incidence-, predictors- and clinical relevance of post-operative tibial rotational malalignment in patients treated with IMN for a tibial shaft fracture, and facilitates future studies on this topic.

Comparison of the Morphology and Histomorphometry of Spermatogenic Cyst of Three Sharks Species With Diametric Testes.

Characterization of the reproductive anatomy of elasmobranchs (sharks, skates, rays, and sawfish) offers unique insights into the evolution of reproductive traits in animals due to their phylogenetic position at the base of the vertebrate tree of life. Yet, despite advances in our understanding of male elasmobranch reproductive physiology and testes histology, very little is known about how testes histomorphometrics varies with male maturation. In this study, we characterize and contrast testes morphology and histomorphology of males at different maturation stages in three shark species with diametric testes development: Prionaceglauca, Rhizoprionodon lalandii, and Mustelus canis. All stages of spermatogenesis were observed in P. glauca and R. lalandii, while for M. canis, only males at early stages of maturation were examined and therefore all the spermatogenesis cells lineage were not present. The number of Sertoli cells increased with cell development by six times in R. lalandii and roughly four times in P. glauca, and were statistically different among stages of spermatogenesis cysts in both species. Statistical differences in cyst diameter and Sertoli cell numbers were observed between P. glauca and R. lalandii. The increase of spermatocyte II cell diameter described for R. Lalandii in this study was not usual to elasmobranch species as compared, for example, to P. glauca. This information proves the importance of studying the testicular development and the process of spermatogenesis is necessary for understanding the reproductive biology of the species, including life cycles and history, variation of reproductive morphology.

Reproduction aspects of cobia caught in Pernambuco Coast, northeastern Brazil / Aspectos da reprodução do beijupirá capturado na costa de Pernambuco, nordeste do Brasil

Aspects of the reproduction of cobia (Rachycentron canadum) population from the coast of Pernambuco State, Northeastern Brazil, were studied from February 2004 to August 2006. One hundred eleven individuals were analyzed: 54 females with fork length (FL) ranging from 40 to 137 cm (mean ± standard deviation: 90.7 ± 18.1 cm) and 57 males with FL from 43 to 114.5 cm (82.4 ± 17.0 cm). Histological analysis was used to identify maturational phases. Spawning capable females were found from August to May, except in December, while mature males were present throughout the year, except in July. Size at first maturity (L50) obtained by Bayesian analysis was 72.51 cm FL for females and 60.69 cm FL for males. Overall batch fecundity ranged from 192,063 to 1,600,513 oocytes (722,398 ± 430,911) and mean relative batch fecundity ranged from 32.9 to 104.8 (71.1 ± 29.8) oocytes per gram of female body weight. The data indicate that the reproduction of cobia off the coast of Pernambuco occurs throughout the year, but with peaks between February and April, period in which gonadosomatic indices reach the maximum values and then decrease until May for females and males.

Innovation in justice: co-production, competence and user satisfaction in judicial mediation / Innovación en el Poder Judicial: coproducción, competencias y satisfacción del usuario en la mediación judicial / Inovação no Judiciário: coprodução, competências e satisfação do usuário na mediação judicial

Abstract This study evaluated the effects of co-production and the mediator's competence on the results of Judicial Mediation in the Court of Justice of the Brazilian Federal District and Territories. Data was collected using satisfaction surveys applied to the parties using the court's judicial mediation services. The sample refers to the period from January 2013 to July 2015, totaling 312 participants and 107 discursive answers. The evaluation adopted techniques of descriptive statistics, exploratory factor analysis, and logistic regression as well as content analysis. The results showed that the only statistically significant variable was the mediator's competence, which increases the likelihood of positive perception about the outcomes of judicial mediation both for citizens and the justice system. Both parties using the services did not perceive that co-production affects the outcomes. This result was due to the complexity of the cases mediated, which makes it hard to observe the role of cooperation in achieving the outcomes. For the citizen, the mediator is primarily responsible for directing the judicial mediation procedure as well as the outcomes achieved through the procedure. We provide recommendations and a research agenda aimed at strengthening research in the area.

Resumen Este estudio evaluó los efectos de la coproducción y las competencias de los mediadores en los resultados de la mediación judicial en el Tribunal de Justicia del Distrito Federal y Territorios. Los datos se recopilaron a través de encuestas de satisfacción de los usuarios realizadas por el Tribunal a los usuarios de los servicios de mediación judicial. La muestra se refiere al período comprendido entre enero de 2013 y julio de 2015, con un total de 312 participantes y 107 respuestas discursivas. La evaluación se realizó mediante técnicas de estadística descriptiva, análisis factorial exploratorio y regresión logística, así como análisis de contenido. Se constató que la única variable estadísticamente significativa era la competencia del mediador, lo que aumenta la probabilidad de una percepción positiva de los resultados de la mediación judicial para el usuario del servicio y el Poder Judicial. También se observó que la coproducción no se percibe como un factor que afecta los resultados del servicio para los ciudadanos o el Poder Judicial. Este resultado se debió a la complejidad de los casos mediados, lo que hizo que la percepción de cooperación para llegar a un resultado sea difícil de observar. Consiguientemente, para el ciudadano, el mediador es el principal responsable de dirigir el procedimiento de mediación judicial, así como de los resultados logrados a través del procedimiento. Finalmente, se enumeran recomendaciones y una agenda de investigación para fortalecer la investigación en el área.

Resumo O presente estudo teve por objetivo testar os efeitos da coprodução e das competências do mediador nos resultados da mediação Judicial no Tribunal de Justiça do Distrito Federal e Territórios - TJDFT, com base na Pesquisa de Satisfação do Usuário - PSU, aplicada pelo TJDFT às partes usuárias dos serviços de mediação judicial. Os dados analisados correspondem à amostra tabulada no período de janeiro de 2013 a julho de 2015, totalizando 312 participantes e 107 respostas discursivas. Os objetivos propostos foram alcançados a partir de técnicas de estatística descritiva, análise fatorial exploratória e regressão logística, além de análise de conteúdo. Por meio dos testes realizados foi constatado que a única variável que apresentou significância estatística foi a de competências do mediador, comprovando-se que as competências do mediador aumentam a probabilidade de percepção positiva dos resultados da Mediação Judicial para o usuário do serviço e para o Judiciário. Tem-se ainda, que a coprodução não pode ser percebida como um fator que impacta nos resultados do serviço para o cidadão e para o judiciário. Esse resultado se deu devido à complexidade dos casos mediados, o que faz com que a percepção de cooperação para se chegar a um resultado seja de difícil observação. Por conseguinte, observa-se que para o cidadão, o mediador é o principal responsável pelo direcionamento do procedimento de mediação judicial, bem como pelos resultados alcançados com o procedimento. Ao final do estudo foram elencadas recomendações e agenda de pesquisa, com vistas ao fortalecimento de pesquisas na área.

Osseointegrated implants placed at supracrestal level may harbour higher counts of A. gerencseriae and S. constellatus - a randomized, controlled pilot study.

PURPOSE: This study aimed at evaluating the bacterial colonization in dental implants inserted in the crestal or supracrestal position and correlated it to radiographic bone measurements. METHODS: Thirty-five implants with regular platform in nine patients (mean age 62.4±11.2 years) were inserted either at the bone crest level (control group) or at a suprecrestal level (test group). Radiographic examination was performed at baseline (implant installation) and after 6 months. Clinical and microbiological data were collected after 6 months. Digital radiography was used to assess bone remodeling (marginal bone loss and optical alveolar density). Bacterial profile was analyzed by checkerboard DNA-DNA hybridization, including a panel of 40 bacterial species. RESULTS: After 6 months, there were significantly higher counts of Actinomyces gerencseriae (p=0.009) and Streptococcus constellatus (p=0.05) in the test group. No significant differences between test and control groups were observed for marginal bone loss (p=0.725) and optical alveolar density (p=0.975). Probing depth was similar in both groups. CONCLUSION: Significantly higher counts of A. gerencseriae and S. constellatus were found in implants placed at the supracrestal level compared to the ones placed at the bone level. No relation was found between the installation level of dental implants and peri-implant bone remodeling.

Resumo Este estudo examinou os efeitos da coprodução e das competências do prestador de serviços nos resultados da conciliação judicial no Tribunal de Justiça do Distrito Federal e Territórios (TJDFT), a partir da percepção de satisfação das partes litigantes e dos advogados usuários do serviço. A conciliação judicial é uma inovação do Poder Judiciário que visa a aumentar a eficiência e o valor gerado pelos serviços de Justiça e trata-se de um processo coproduzido, no qual os usuários participam da prestação dos serviços públicos. Para alcançar o objetivo proposto, utilizaram-se dados secundários provenientes da pesquisa de satisfação do usuário elaborada e aplicada pela equipe técnica do TJDFT e a amostra final, após o tratamento dos dados, consistiu em 1.735 partes litigantes e 764 advogados. Para análise dos dados, aplicaram-se as técnicas de análise fatorial exploratória e de regressão logística e os resultados sugerem que a coprodução é a variável com maior poder preditivo dos resultados do serviço, tanto para o cidadão como para a imagem do Poder Judiciário, na perspectiva das partes. Por fim, os resultados do serviço para o cidadão, se positivos, aumentam a probabilidade da imagem do Poder Judiciário também ser positiva, na percepção dos dois grupos investigados.

Abstract This study examined the effects of coproduction and the competencies of the service provider on the results of the Judicial Conciliation at the State Courthouse of Distrito Federal, based on the satisfaction of the litigants and lawyers who used the service. The Judicial Conciliation is an innovation to increase efficiency and results for the general public and is a coproduced process, in which the users play an essential role in the provision of public services. The study used secondary data obtained from a customer satisfaction survey designed by the TJDFT. The final research sample consisted of 1,735 litigants and 764 lawyers. For the data analysis, exploratory factor analysis and logistic regression were used, and the results of the regressions suggest that coproduction is the variable that best explains the results of the service for the customers as well as for the reputation of the Judiciary, from the perception of the litigants. Finally, the perception that the service was beneficial to citizens increases the likelihood of the customer to develop a positive image of the Judiciary, according to the results obtained both in the litigants' and lawyers' samples.

Morphological description of ovary and uterus of the nurse shark (Ginglymostoma cirratum) caught off at the Fortaleza coast, Northeast Brazil / Descrição morfológica de ovário e útero de Tubarões-lixa (Ginglymostoma cirratum) capturados na costa de Fortaleza, Nordeste do Brasil

The nurse shark, Ginglymostoma cirratum (Bonnaterre, 1778) is one of the most studied species of elasmobranchs. However, the knowledge of their reproductive biology is still relatively rare, particularly in the western South Atlantic. This study aimed to describe the morphology of the uterus and the ovary of G. cirratum, based on specimens caught off at the Fortaleza/CE coast, northeast Brazil. Samples were collected from September 2012 to June 2013, from regular landings of artisanal fishing, which commercialize this species freely. A total of ten females were collected. The methodologies followed for analyzing the ovaries and uterus of those females included both macroscopic and histological analysis. G. cirratum has internal type ovary morphology, with invaginations of connective tissue, which defines compartments and separate oocyte groups in ovigerous lots. The epithelium lining the ovary changes from simple columnar ciliated in the area without ovigerous lots, which turns into a simple cubic epithelium in the coating portion of the epigonal organ where ovarian tissue is absent. The uterine mucosa has secretory cells denoted by Alcian Blue staining, indicating the production of mucopolysaccharides, even in immature individuals. This lecithotrophic shark has a uterine vascularized mucosa that is one characteristic of viviparous elasmobranch species.(AU)

O tubarão-lixa, Ginglymostoma cirratum (Bonnaterre, 1778) é uma das espécies mais estudadas de elasmobrânquios. O conhecimento de sua biologia reprodutiva, no entanto, ainda é relativamente raro, particularmente no Oeste do Atlântico Sul. Este estudo objetivou a descrição morfológica do útero e ovário de G. cirratum, baseado em espécimes capturados na costa de Fortaleza/CE, no Nordeste do Brasil. Um total de dez fêmeas foi coletado de setembro de 2012 a junho de 2013, nos desembarques regulares da pesca artesanal, que comercializam essa espécie livremente. A metodologia foi de acordo com as analises macroscópica e histológica dos ovários e útero. G. cirratum tem o tipo de morfologia de ovário interno, com invaginações de tecido conjuntivo, que define compartimentos e separa grupos de oócitos em lotes ovígeros. O epitélio que reveste o ovário varia de epitélio simples colunar ciliado na área que não apresenta lotes ovígeros para epitélio simples cúbico na porção de revestimento do órgão epigonal, onde o tecido ovariano é ausente. A mucosa uterina possui células secretoras, evidenciadas pela coloração em Alcian Blue, indicando a produção de mucopolissacarídeos, mesmo em indivíduos imaturos. Este tubarão lecitotrófico apresenta a mucosa uterina vascularizada, sendo esta uma característica de espécies de elasmobrânquios vivíparos.(AU)

This study aimed to describe the morphology of the uterus and the ovary of G. cirratum, based on specimens caught off at the Fortaleza/CE coast, northeast Brazil. Samples were collected from September 2012 to June 2013, from regular landings of artisanal fishing, which commercialize this species freely. A total of ten females were collected. The methodologies followed for analyzing the ovaries and uterus of those females included both macroscopic and histological analysis. G. cirratum has internal type ovary morphology, with invaginations of connective tissue, which defines compartments and separate oocyte groups in ovigerous lots. The epithelium lining the ovary changes from simple columnar ciliated in the area without ovigerous lots, which turns into a simple cubic epithelium in the coating portion of the epigonal organ where ovarian tissue is absent. The uterine mucosa has secretory cells denoted by Alcian Blue staining, indicating the production of mucopolysaccharides, even in immature individuals. This lecithotrophic shark has a uterine vascularized mucosa that is one characteristic of viviparous elasmobranch species.(AU)

Mapeamento de competências de suporte e de apoio pedagógico e administrativo de profissionais que atuam na modalidade a distância / Mapping the management and pedagogical support competences of professionals working with distance learning

RESUMO: O presente estudo teve como objetivo diagnosticar, empiricamente, as competências profissionais (técnicas e comportamentais), de apoio e suporte administrativo, pedagógico e secretarial, de cursos a distância ofertados no âmbito da Universidade Aberta do Brasil. Por meio de duas etapas empíricas foi realizada pesquisa com desenho multimétodo sequencial, que envolveu fase qualitativa, composta por análise documental e realização de nove entrevistas semiestruturadas, e fase quantitativa, com aplicação de questionário totalmente estruturado. O tratamento dos dados foi feito por análise de conteúdo e análise estatística. Os resultados indicaram baixas lacunas de competência, o que sugere que as atividades de captação, treinamento e desenvolvimento de competências provavelmente têm sido realizadas de forma condizente com as necessidades das atribuições das equipes secretariais e de apoio. Recomenda-se, para pesquisas futuras, que se utilize avaliação por múltiplas fontes e a validação psicométrica do instrumento de competência, para identificar suas evidências de validade interna e externa.

ABSTRACT: The aim of the present study was to empirically diagnose the professional competencies (technical and behavioral) concerning the management, pedagogical and secretarial support in distance learning courses provided by Brazil Open University. A sequential mixed model design was applied through two empirical stages, which encompassed one qualitative stage composed of documental analysis and of the conduction of nine semi-structured interviews; and the was based on the application of a totally structured questionnaire. Data treatment was conducted through content and statistical analysis. Results showed low competence gaps, fact that suggests that activities focused on recruitment, training and on competence development have been possibly performed in compliance with the attributes needed by the secretarial and support teams. It is recommended to apply data evaluations based on multiple sources and on the psychometric validation of the competence instrument in further studies in order to identify its internal and external validity evidences.

Planning and treatment in oral rehabilitation with implant-supported prostheses using cephalometric analysis / Planejamento e tratamento em reabilitação oral com próteses sobre implantes usando análise cefalométrica

There are growing prosthetic and esthetic demands for Oral Rehabilitations on osseointegratable implants, requiring precise prosthetic-surgical planning. In edentulous patients planning may be done using cephalometric analysis to determine the position of the teeth in the dental prosthesis, and consequently, those of the implants. In this clinical case, the planning and treatment of an oral implant-supported rehabilitation is described, using cephalometry to optimize prosthetic success and patient comfort. The patient presented complete mandibular and partial maxillary edentulism, with unsatisfactory esthetics and function of the anterior teeth, with accentuated vestibular inclination. In order to determine the correct position of maxillary teeth it was necessary to use a Steiner cephalometric tracing to position the maxillary central incisor in the diagnostic wax-up. Therefore, the maxillary anterior teeth were extracted, osseointegratable implants were placed (Neodent(r), Curitiba, Brazil), and an immediate temporary fixed denture was inserted. After 30 days, surgery was performed for the placement of 4 osseointegratable implants (Neodent(r), Curitiba, Brazil) in the inter-mentonian region, on which a complete, temporary, implant-supported denture was placed. After the period of osseointegration, the definitive implant-supported dental prosthesis were fabricated.

Reabilitações orais sobre implantes osteointegráveis enfrentam crescentes exigências protéticas e estéticas, necessitando de um planejamento protético-cirúrgico preciso. O planejamento em pacientes edêntulos pode ser realizado usando análise cefalométrica para determinar o posicionamento dos dentes na prótese e conseqüentemente dos implantes. Esse caso clínico descreve o planejamento e tratamento de uma reabilitação oral sobre implantes usando análise cefalométrica para otimizar o sucesso protético assim como o conforto do paciente. Paciente apresentando edentulismo total mandibular e parcial maxilar com elementos anteriores insatisfatórios estética e funcionalmente, com inclinação vestibular acentuada. Para a determinação do correto posicionamento dos elementos superiores foi necessário a utilização de traçado cefalométrico de Steiner para o posicionamento do incisivo central superior no enceramento diagnóstico. Dessa forma, foi realizado exodontia dos elementos anteriores superiores, instalação de implantes osteointegraveis (Neodent(r), Curitiba, Brasil) e instalação de prótese fixa provisória imediata. Após 30 dias, foi realizada cirurgia para instalação de 4 implantes osteointegráveis (Neodent(r), Curitiba, Brasil) na região intermentoniana, sobre os quais foi instalada uma prótese total implanto-suportada inferior provisória. Após período de osteointegração, as próteses sobre implantes definitivas foram confeccionadas.

Influence of application site of provisional cement on the marginal adaptation of provisional crowns.

INTRODUCTION: Marginal discrepancies may lead to cement washout and marginal leakage, damaging periodontal and pulp tissues or causing premature loss of the restoration. PURPOSE: This study evaluated the influence of application site of provisional cement on the marginal adaptation of provisional crowns. MATERIAL AND METHODS: Four different application sites of provisional cement (Temp Bond NE, Kerr Corporation) were used for cementation of provisional crowns on phantom teeth prepared for full crown restorations, performing 4 experimental groups (n=10): cement applied to all internal surfaces of the crown (CAO); cement applied to all internal surfaces of the crown, except for the occlusal surface (CA); cement applied to the cervical crown margin (CM); and cement applied to the cervical tooth margin (TM). A comparison microscope (Mitutoyo America Corporation) was used to measure the distances between the internal tangents of two circular marks, one made on the provisional crown and one made apical to the tooth preparation margin, in areas corresponding to buccal, lingual, mesial and distal surfaces. Marginal adaptation was determined before and after cementation, with 0.0001-mm accuracy. Data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. RESULTS: Mean values of marginal opening obtained for each group were: CAO: 145 microm; CA: 67 microm; CM: 46 microm; TM: 34 microm. CA, CM and TM presented significantly lower marginal openings than CAO (p<0.05). CONCLUSION: complete filling of the crown with provisional cement, including the occlusal surface, provided greater marginal discrepancies when compared to the other methods evaluated.
