AVALIAÇÃO TOMOGRÁFICA DA INCLINAÇÃO E DAS TÁBUAS ÓSSEAS VESTIBULAR E LINGUAL DE INCISIVOS NO TRATAMENTO DA CLASSE II DIVISÃO 1 COM O APARELHO FORSUS®

O objetivo deste estudo prospectivo foi avaliar os efeitos do aparelho Forsus® nos incisivos centrais superiores e inferiores. A amostra constituiu-se de 22 tomografias computadorizadas de 11 pacientes (sexo masculino e feminino) idade média de 15,8 anos com má oclusão de Classe II que foram tratados com o aparelho Forsus® na clínica do programa de pós-graduação em Odontologia, área de concentração Ortodontia, da Universidade Metodista de São Paulo. As tomografias foram obtidas em dois momentos T1 (final de nivelamento e antes da instalação do Forsus® e T2 (remoção do Forsus®). Para avaliar a distância do ápice até a tábua óssea, as imagens a serem examinadas foram obtidas com o auxílio do viewer do próprio i-CAT® , o iCATVision® e examinadas com o CorelDRAW X5® já para as medidas cefalométricas IMPA e 1.PP as imagens cefalométricas ortogonais foram obtidas em proporção 1:1 com auxílio do software Dolphin 3D® (Dolphin Imaging and Management Solutions, Chatsworth, EUA) e em seguida examinadas com o software Radiocef Studio 2 (Radio Memory, Belo Horizonte, Brasil). Para a obtenção do erro intra-examinador foi feito o teste t de Student pareado para o erro sistemático e a fórmula de DAHLBERG para estimar a ordem de grandeza dos erros casuais e na análise estatística dos resultados utilizou-se: o teste t para a determinação das diferenças entres as fases de observação e o teste de correlação de Pearson para avaliar a correlação entres as alterações. Observou-se: um aumento significativo (p<0,05) tanto no IMPA quanto no 1.PP, aproximação do ápice dos incisivos inferiores da tábua óssea lingual, aproximação do ápice dos incisivos superiores da tábua óssea vestibular, uma correlação negativa muito forte entre o IMPA e a distância do ápice do incisivo até a tábua óssea lingual e uma correlação negativa moderada entre 1.PP e a distância do ápice do incisivo até a tábua óssea vestibular. Sendo assim o aparelho Forsus® no tratamento da Classe II teve como efeito: vestibularização significativa dos incisivos centrais inferiores, uma verticalização significativa dos incisivos centrais superiores, aproximação do ápice dos incisivos inferiores da cortical óssea lingual e aproximação do ápice dos incisivos superiores da cortical óssea vestibular.

Avaliação da qualidade da assistência à mulher e ao filho durante o parto normal

The practices developed in the everyday life of obstetric services are sometimes out of step with the recommendations of the public health policies. Accordingly, this research had the objective of assessing the quality of the care provided to women and children during cases of natural childbirth in municipal public maternity wards of the city of Natal/RN, Brazilian Northeast. We developed a cross-sectional and quantitative study in two maternity wards that provide care actions to pregnant women at regular risk (maternity wards A and B). The participants were 314 puerperal women who were treated during the period between April and July 2014, whose children were born alive, through transpelvic way, with spontaneous or induced beginning of labor and that showed physical and emotional conditions to respond to the proposed questions. The data collection instrument was constructed on the basis of the recommendations of the World Health Organization focused on the care of normal childbirth and validated by skilled judges, and the final version has obtained optimum agreement (k = 0,96; IVC = 0,99). Associated with these recommendations, we used three indicators: percentage of women with induced labor or subjected to elective cesarean section (Indicator A); percentage of women served by a qualified health professional during labor and childbirth (Indicator B); and Bologna Index (Indicator C). The research obtained a favorable opinion of the Research Ethics Committee from the Federal University of Rio Grande do Norte, under the nº 562.313 and Certificate of Presentation for Ethics Appreciation: 25958513.0.0000.5537. The analysis of categories related to the recommendations of the World Health Organization was conducted by means of absolute and relative frequency and the Chi-square Pearson’s and Fisher’s exact tests made the comparison of the differences observed between the two maternity wards. Furthermore, we calculated the percentage of the indicators A and B and with the results of the Indicator C, the quality was assessed as follows: the closer to 5, the better will be the quality, and the closer to 0, the worst will be the quality, and the Mann-Whitney U test was used to compare the differences of the obtained averages. The significance level of 5% was considered in all statistical tests. The differences between the maternity wards were identified with regard to the provision of liquids orally (p=0,018), stimulus for non-supine positions (p=0,002), existence of partograph (p=0,001), support or welcoming by health professionals (p= 0,047), intravenous infusion (p<0,001), supine position (p<0,001), use of oxytocin (p<0,001), food and liquid restriction (p= 0,002) and, lastly, the fact of the touch is performed by more than 1 examiner (p=0,011). The indicators A and B showed percentages of 13,09% and 100%, respectively. The overall average of the Indicator C was equal to 2,07 (± 0,74). There was a statistically significant difference between the averages of the maternity wards (p<0,001). The care actions provided during the process of labor and childbirth is inappropriate, especially in the maternity ward B. It is necessary to implement improvements and redesign the obstetric model in force

Análise cefalométrica: ortodontistas x radiologistas

Cephalometric analysis is the mensuration of linear and angular measures through demarcation points as distances and lines on teleradiography, and is considered of fundamental importance for diagnosis and orthodontic planning. In this manner, the objective of this research was to compare cephalometric measurements obtained by dentists and radiologists from the analysis of the same radiograph, in a computerized cephalometric analysis program. All research participants marked 18 cephalometric points on a 14-inch notebook computer, as directed by the program itself (Radiocef 2®). From there, they generated 14 cephalometric parameters including skeletal, dental-skeletal, dental and soft tissue. In order to verify the intra-examiner agreement, 10 professionals from each group repeated the marking of the points with a minimum interval of eight days between the two markings. The intra-group variability was calculated based on the coefficients of variation (CV). The comparison between groups was performed using the Student t-test for normally distributed variables, and using the Mann-Whitney test for those with non-normal distribution. In the group of orthodontists, the measurements of Pog and 1-NB, SL, S-Ls Line, S-Li Line and 1.NB showed high internal variability. In the group of radiologists, the same occurred with the values of Pog and 1-NB, S-Ls Line, S-Li Line and 1.NA. In the comparison between groups, all the analyzed linear values and two angular values showed statistically significant differences between radiologists and dentists (p <0.05). According to the results, the interexaminer error in cephalometric analysis requires more attention, but does not come from a specific class of specialists, being either dentists or radiologists.

Influência da paridade, do tipo de parto e do nível de atividade física sobre a musculatura do assoalho pélvico em mulheres na pós-menopausa

The post-menopause stage is characterized by hormonal and organic alterations of ovarian failure. One of the most important of these is muscles alterations of the pelvic floor (MPF). According to current literature, in young women gynecological and obstetric factors, as well as lifestyles and habits influence that loss of function. However, there is still uncertainty about the influence of those variables in the MPF functions in post-menopause women. Thus, this study aimed at seeing if there is an influence from number of births, the type of birth and the level of physical activity on the MPF of post-menopause women. Another objective of this study was to compare MPF force in women who had had vaginal births with those who had been subjected to cesarean sections, those with different levels of physical activity and those with artificial and natural menopause in the initial and latter stages. Furthermore, the test of muscular force was compared to perineometry. Using observational, analytical and transversal observations, 100 women in the post-menopausal stage of life, between the ages of 45 and 65, were examined. They were divided according to the menopausal stage into three groups: women who had undergone hysterectomies, those in the initial stages of postmenopause and those in the late stage of postmenpause. The patients were questioned about social, demographic, gynecological and obstetric factors. All the volunteers were submitted to a physical examination where their height and weight were measured to arrive at the corporal mass index and their waist measurements were taken. The evaluation of the pelvic floor was conducted with muscular force tests and perineometry. These results were analyzed with statistical description and ANOVA statistical tests, multiple regression and Kolmogorov-Smirnov evaluations. The results showed homogeneity with regard to social demographic and anthropometric characteristics among the women in the final test sample (n=85). It was also seen that most of the women in all three groups were married (p=0.51) and catholic (p=0.13). The average per capital income varied between $R585.47 (+/-466.67) and $R1,271.83 (+/-1,748.95), with no significant difference between the groups (p=0.05). The G>6 group presented an average age between 58.95 (+/-3.96) which was significantly greater that the G<6 group´s average age (53.21+/- 3.88) (p=0.000). There was no difference between the groups´ anthropometric characteristics of weight (p=0.32), height (p=0.72) and corporal mass index (p=0.34), nor in the waist measurements (p=0.33). Furthermore, no significant difference was noted in the MPF function of women who had had normal births, cesarean sections or a combination of the two (TFM p=0.897; perineum measurement p=0.502). Likewise, no differences were seen in the MPF function of women who had one, two to three or four or more births (TFM p=0.28, perineum measurement p=0.13). Finally, no difference was perceived among those with different levels of physical activity (TFM p=0.663; perineum measurement p=0.741). Therefore, we found that the type of delivery, number of births and physical activity had no influence on the muscular function of the pelvic floor among the women studied. It is believed that decline in muscular function in post-menopause women is fundamentally related to the process of aging.

Estudo Clínico Longitudinal Comparativo da Condição Periodontal de Pilares Diretos de Próteses Parciais Removíveis Dento- Suportada e Dento-Muco-Suportada

Objective: To perform a long-term clinical evaluation of the periodontium of removable parti al denture (RPD) wearers, comparing the direct pillar teeth of tooth-supported and toothtissue supported RPDs. Method: Fifty patients with mean age of 45 years were enrolled in the study. The individuals were examined by a single examiner at the moment of denture installation and after 3, 6, 9 and 12 months. In each exam, the following parameters were verified: gingival recession (GR), probing depth (PD), plaque index (PI), gingival index (GI) e amount kerati nized mucosa (KM). All patients received oral hygiene instructions and prophylaxis and, when necessary, scaling and root planing. An analysis from the confidence interval was done to evaluate the endpoints regarding the type of denture in the direct pillar group. Results: The tooth-tissue supported dentures showed significantly higher GR, GI and PI values, and significantly lower KM values. Over time, neither of the types of denture presented statistically significant difference from the initial to the final examination for the parameters GR, PD, KM and GI, while the PI was significant only for the tooth-supported dentures. Conclusion: Pillar teeth adjacent to free ends presented a less favorable periodontal conditi on than the pillar teeth adjacent to intercalated spaces. However, the use of RPD did not aggravate the initial condition, after a follow-up period of 12 months. The findings of the study indicate that, within 1 year, there were no significant differences between the direct pillars of the toothsupported and tooth-ti ssue supported dentures, and suggest the need of professional follow up for a longer period.

Associação da depressão e distúrbio do sono em pacientes com e sem disfunção temporomandibular

Objective: To evaluate the inter-relationship between TMD (temporomandibular disorder), depression and sleep disorder. Methods: This is a case-control study with questionnaires in 111 patients, allocated from the Dentistry Department of UFRN, Natal, Brazil, from September 2014 to June 2015, for evaluation of depressive symptoms through the BDI (Beck Depression Inventory); sleep disorder, the PSQI (Pittsburgh Sleep Quality Index) and DTM through the RDC / TMD (diagnostic criteria to search for DTM). All indexes were applied by a single examiner previously trained and calibrated. The collected data were analyzed with chi-square tests of Pearson (χ2) and the unconditional logistic regression. Results: women had a risk of 2.85 times more likely to develop TMD (p = 0.046). The OR (odds ratio) shows that sleep disturbance increases by 2.19 the chances of having TMD (p = 0.062) and depressive symptoms increase the risk by 3.16 times in developing dysfunction (p = 0.053). Conclusion: The data of this research allows us to conclude that patients with TMD, in this population, were more likely to develop changes in sleep and depressive symptoms.

Diagnóstico ecográfico de tumores anexiais: modelos do grupo international ovary tumor analysis (IOTA) versus classificação gynecologic imaging report and data system (GI-RADS)

A ecografia é o exame de primeira linha na identificação e caraterização de tumores anexiais. Foram descritos diversos métodos de diagnóstico diferencial incluindo a avaliação subjetiva do observador, índices descritivos simples e índices matematicamente desenvolvidos como modelos de regressão logística, continuando a avaliação subjectiva por examinador diferenciado a ser o melhor método de discriminação entre tumores malignos e benignos. No entanto, devido à subjectividade inerente a esta avaliação tornouse necessário estabelecer uma nomenclatura padronizada e uma classificação que facilitasse a comunicação de resultados e respectivas recomendações de vigilância. O objetivo deste artigo é resumir e comparar diferentes métodos de avaliação e classificação de tumores anexiais, nomeadamente os modelos do grupo International Ovary Tumor Analysis (IOTA) e a classificação Gynecologic Imaging Report and Data System (GI-RADS), em termos de desempenho diagnóstico e utilidade na prática clínica.

Estudio comparativo de la fiabilidad y reproducibilidad en la medición de los tamaños dentarios y las medidas de las arcadas dentarias entre registros manuales y digitales 3d obtenidos por escaneado intraoral y extraoral

Tradicionalmente, los ortodoncistas han realizado las mediciones dentales en los modelos de yeso, pero los avances tecnológicos permiten ahora a los ortodoncistas realizar esas mediciones en los modelos digitales. El propósito de este estudio fue comparar la fiabilidad y reproducibilidad de las medidas de los tamaños dentarios y las arcadas dentarias entre el método manual y los métodos digitales 3D obtenidos por un escáner intraoral CEREC Omnicam (Sirona Dental Systems) y dos escáneres extraorales: inEos X5 (Sirona Dental Systems) y Dental Scanner SMART (Open Technologies). Un modelo de yeso, un escaneado intraoral y dos modelos digitales con un escáner extraoral fueron realizadas para cada uno de los 20 sujetos. Las medidas de los tamaños dentarios, la distancia intercanina y la distancia intermolar de los modelos digitales se compararon con los correspondientes modelos de yeso (estándar de oro) Se utilizó el test de ANOVA para establecer la fiabilidad entre los cuatro métodos y el coeficiente de correlación intraclase fue calculado para determinar la reproducibilidad intra- e inter-examinador. Los resultados encontrados fueron que no existieron diferencias estadísticamente significativas entre las medidas hechas directamente en los modelos de yeso y los modelos digitales. Los coeficientes de correlación intraclase tanto intra- e inter-examinador fue alto y considerado bueno para los cuatro métodos de medición. CCI> 0.90. Se concluyó que las mediciones en los modelos digitales obtenidos con un escáner extraoral e intraoral son fiables y reproducibles

A misericórdia do Porto e os seus hospitais como centros de formação de cirurgiões (1639-1825)

Desde o início do século XVI que a Coroa portuguesa investiu na regulação das “artes da cura”, de formação académica mas também empírica, com o propósito de organizar um campo em completa desordem, de que resultavam “grandes perdas para o reino”. No entanto, a estrutura então criada assentou em entidades concorrenciais, com poderes sobrepostos e em permanente conflito, elementos determinantes para o estudo da construção das profissões de saúde no período moderno. Entre estas, o domínio era dos cirurgiões, que aprendiam pela prática quotidiana, às vezes em contexto hospitalar. O hospital administrado pela Misericórdia do Porto foi um dos principais centros formadores de cirurgiões a nível nacional, condição que, por sua vez, facilitava o acesso à carreira de examinador. Como se organizava o ensino da cirurgia no hospital da Misericórdia do Porto? Quem foram os seus professores e quantos alunos licenciaram? Que redes construíram e como as geriram? Serão estas algumas das questões a que se procurará dar resposta na presente comunicação. O trabalho a apresentar assume‑se como uma mera abordagem preliminar e exploratória a uma base de dados que reúne cerca de 20 mil licenças para o exercício de várias profissões de saúde, em Portugal e no Império, atribuídas e/ou reconhecidas por diferentes organismos da administração central entre os finais do século XV e 1825, ano em que, através das Escolas Medico‑Cirurgicas, se constituiu um novo paradigma de formação de cirurgiões. Basicamente serão testadas as relações entre o hospital e outras entidades com competências para examinar praticantes de cirurgia, perscrutando‑se a influência de possíveis círculos pessoais e profissionais bem como o seu raio de acção. O objectivo principal será o de procurar padrões de actuação e identificar tendências dominantes que permitam construir hipóteses de análise que possam ser aplicadas a todo o país.
