The purpose of this paper is to identify the utilization of two models of orthotics used in the conservative treatment of rizartrose in patients/consumers that were referred by the medical clinic to the LAI (Laboratory of Integrated Accessibility). It describes this group s perception related to the functional aspects of the two models, evaluates the value of the product attributed by the patient/consumer and describes the importance attributed to each model. The research s objective consists in identifying which model this is preferred from the point of view by the patients that use either the dorsal or ventral models used in the conservative treatment of rizartrose . This work is then based on the exploratory research through the investigation of the bibliography available and in the research field. The research field used the case study methodology to investigate the phenomenon in the real context. The data were collected using a patient questionnaire during two times after the use of the dorsal orthotic and after the use of the ventral orthotic. The questionnaire was used to identify the relationship between the patients/consumers and the two different types of orthotics. A general descriptive analysis was used in order to verify the patient s abilities executing certain activities daily living using the dorsal and ventral orthotics, the product s functional aspects and its value from the patient s/consumer s point of view. The results show that the preference for the dorsal or ventral models is determined by the individual needs of each person. The results also show that other variables, such as the use of the orthotic on the dominant or non-dominant hand, play a role in the preferred model by the patient/consumer and need to be further investigated

The literature has shown a relation between periodontics and the removable partial denture (RPD), with progressive destruction observed in the support structures. The aim of this study was to clinically assess periodontal condition in users of removal partial denture (RPD), and compare right abutments teeth, indirect abutments and controls before installation and after 1 year, in addition to comparing tooth-supported and tooth mucosa-supported abutments. A total of 50 patients, 32 women and 18 men, mean age of 45 years, took part in the study. The patients were examined by a single examiner at prosthesis installation and after 3, 6, 9 and 12 months. The following were verified at each examination: Probe Depth (PD), Plaque Index (PI), Gingival Index (GI), the amount of Keratinized Mucosa (KM), Gingival Recession (GR) and Dental Mobility (DM); in addition patients received oral hygiene orientation, accompanied by prophylaxis, periodontal scaling and root planing (PSRP), when necessary. Analysis of Variance (ANOVA) with Tukey-Kramer post test was used to assess the dependent variables (PD, PI, KM, GR) of the three groups over time while Friedman s test was used for GI. To assess the outcomes of prosthesis type in the right abutment group, a confidence interval-based analysis was performed. The results showed that the control group was the least compromised in all the variables studied. With respect to development of the groups over time, it was verified that the measures for GR, PD, GI and KM increased from initial examination to 1 year of use in all the groups, but only PI showed a significant increase. There was a non-discriminatory low prevalence of dental mobility. The tooth mucosa-supported prosthesis had significantly higher values for GR, GI and PI and significantly lower ones for KM when compared to tooth-supported. Over time, both types of prostheses showed no significant differences from initial to final examination for the variables GR, PD, KM and GI, with PI significant only for tooth-supported. The results showed that the teeth most involved in RPD design had greater potential of periodontal damage, probably because of greater dental biofilm accumulation. Abutments elements adjacent to the free extremities had less favorable periodontal condition than those adjacent to interpolated spaces, but the use of RPD did not worsen the initial condition

Th17 cells have been strongly associated with the pathogenesis of several autoimmune and inflammatory diseases. IL-17 and IL-23 are important cytokines associated with this lineage. The aim of this study was to analyze, through immunohistochemical methods, the immunoexpression of IL-17 and IL-23 in the inflammatory infiltrate of oral lichen planus (OLP) lesion compared to that of inflammatory fibrous hyperplasia (IFH) and between clinical forms reticular and erosive of OLP. The sample included 41 cases of OLP, of which 23 were reticular and 18 erosive and 10 cases of IFH. The results were subjected to nonparametric statistical tests with a 5% significance level. In OLP lesions histomorphological analysis, the most common findings were: hyperparakeratinization, specimens with atrophic epithelium in erosive clinical form (p = 0.011), epithelial projections in most of reticular type of lesions, in addition Civatte bodies were identified in most samples of both clinical forms. For immunohistochemistry analysis, five fields with strong immunoreactivity for IL-17 and IL-23 were photomicrographed at 400x magnification, images were transferred to a computer where with ImageJ software®, lymphocytes that exhibited cytoplasmic immunostaining for these cytokines were counted. A mean was established after for each case. There was no statistically significant difference in the number of imunopositive lymphocytes for IL-17 and IL-23 among the group of OLP and IFH group, however a larger amount of lymphocytes imunopositive for IL-17 was found in the LPO group (p = 0.079) and significantly higher amounts of those lymphocytes were found in the erosive OLP when compared to the group of reticular OLP and IFH (p = 0.019). Furthermore, a marker epithelial immunopositivity for IL-17 was observed in OLP group. Although the results of this study do not permit the forceful assertion about the participation of Th17 lineage in OLP lesions, the findings of immunopositive lymphocytes counting for IL-17 and IL-23, which are potent proinflammatory cytokines, together with the the marked epithelial immunopositivity found for IL-17 in this study, suggest a possible role of this lineage in the pathogenesis of this disorder

Periodontal disease is an infectious disease resulting from the immunoinflammatory response of the host to microorganisms present in the dental biofilm which causes tissue destruction. The objective of this study was to evaluate the immunohistochemical expression of cyclophilin A (CYPA), extracellular matrix metalloproteinase inducer (EMMPRIN) and matrix metalloproteinase 7 (MMP-7) in human specimens of clinically healthy gingiva (n=32), biofilm-induced gingivitis (n=28), and chronic periodontitis (n=30). Immunopositivity for CYPA, EMMPRIN and MMP-7 differed significantly between the three groups, with higher percentages of staining in chronic periodontitis specimens, followed by chronic gingivitis and healthy gingiva specimens (p < 0.001). Immunoexpression of CYPA and MMP-7 was higher in the intense inflammatory infiltrate observed mainly in cases of periodontitis. Analysis of possible correlations between the immunoexpression of EMMPRIN, MMP-7 and CYPA and between the expression of these proteins and clinical parameters (probing depth and clinical attachment loss) showed a positive correlation of CYPA expression with MMP-7 (r = 0.831; p < 0.001) and EMMPRIN (r = 0.289; p = 0.006). In addition, there was a significant positive correlation between probing depth and expression of MMP-7 (r = 0.726; p < 0.001), EMMPRIN (r = 0.345; p = 0.001), and CYPA (r = 0.803; p < 0.001). These results suggest that CYPA, EMMPRIN and MMP-7 are associated with the pathogenesis and progression of periodontal disease

This research aimed to investigate the place of social policies in Psychology undergraduate programs from Piauí/Brazil. A documental study was done by analysing the Projeto Pedagógico de Curso (PPC) from five universities. Also, interviews were conducted, for each program, with a coordinator and a professor who teaches subjects related to social policies. The main results indicates that the Psychology undergraduate programs in Piauí are recent, created between the late 1990s and early 2000s, when professionals in this area were in demand. The social policies appear in PPC related to student profile; curricula emphasis, subjects and internships; albeit in a peripheral condition. Furthermore, disconnection between proposed profile and the curriculum; fragmentation and insufficient content about social policies; and predominance of clinical area were perceived in these institutions. It is noteworthy that health policies stand out in PPC while social assistance policy or other social policies were poorly mentioned. Therefore, the place of social policies must be reviewed in Psychology undergraduate programs from Piauí in order to include other social policies and improve the subjects articulation, assuming a central, critical and policy perspective

The evaluation criteria of the cases treated with dental implants are based on clinical and radiographic tests. In this context it is important to conduct research to determine prognosis of different types of prosthetic rehabilitation and determination of the main problems affecting this type of treatment. Thus, the objective of this study was to assess the prosthetic conditions of individuals rehabilitated with implant-supported prosthesis. In this cross-sectional study 153 patients were treated, accounting for a sample of 509 implants. The failures were observed by clinical and radiographic examination. The results showed that the fracture (0.2%) loss (0.4%) and loosening of the screws (3.3%) were failures are less frequent. The fracture structures as the resin (12.4%), porcelain (5.5%) and metallic (1.5%), loss of resin that covers the screw (23.8%) and loss of retention overdentures on implants (18.6%) had a higher occurrence. The failure of adaptation between the abutment and the implant (6.9%) and especially between the prosthesis and the abutment (25.4%) had a high prevalence and, when related to other parameters showed a significant association, particularly with the cemented prosthesis (OR = 6.79). It can be concluded that to minimize the appearance of failures, protocols must be observed from diagnosis to the settlement and control of prostheses on implants, particularly with respect to technical steps of the making of the prosthesis and care in radiographic evaluating the fit between their components

Tem sido demonstrado que o diabetes influencia no desenvolvimento e progressão da doença periodontal. Acredita-se ainda que há uma relação bi-direcional entre o Diabetes Mellito e a Doença Periodontal. Por isso, o tratamento periodontal pode responder de forma diferente em pacientes com e sem o quadro de diabetes. O objetivo desse estudo foi avaliar clinicamente o efeito da terapia periodontal não cirúrgica em pacientes com periodontite e diabetes mellito (grupo teste) e sem o quadro de diabetes (grupo controle). Para isso, realizou-se o tratamento periodontal não-cirúrgico FMSRP (Full mouth Scalling and Root Planing) e verificou-se os parâmetro clínicos periodontais (profundidade de sondagem, nível clínico de inserção, mobilidade, índice gengival e índice de placa) no início do estudo e após 3 meses. Na análise estatística, o paciente foi considerado como unidade de análise (p<0,05). Para as variáveis categóricas utilizou-se o teste de Fisher. Nas comparações inter-grupo, foi utilizado o Mann-Whitney Test e para comparações intra-grupo (baseline e três meses) utilizou-se o Teste de Wilcoxon. Participaram 26 pacientes no grupo controle e 14 no grupo teste. O índice de placa era 71,20% no início do estudo para o grupo teste e ficou 47,12% no fim; já no controle, os valores eram de 48,52% passando para 37,50%. E o índice gengival no grupo teste no baseline era 42,67 diminuindo para 26,81 e no grupo controle diminuiu de 41,36 para 30,62. A profundidade de sondagem foi no grupo teste 2,71mm passando para 2,40mm; já no controle, os valores foram de 2,84mm diminuindo para 2,55mm. O grupo controle ganhou 0,34 mm de inserção e o grupo teste perdeu 0,44mm de inserção. A recessão gengival aumentou 0,33mm no grupo teste e 0,04mm no grupo controle após os 3 meses. Houve diferença significativa inter-grupo para o índice de placa e gengival no baseline, também foi encontrado na recessão após 3 meses; já intra-grupo verificou-se diferença significativa para todas as variáveis, exceto para o nível clinico de inserção e mobilidade. Quando se categorizou a profundidade de sondagem em ≤3mm, >3 e≤6mm e >6mm, não foi encontrado diferença entre os grupos, mas verificou-se diferença significativa entre os períodos tanto para o grupo teste como para o controle. A hemoglobina glicada no grupo controle foi de 5,90% e no teste aumentou de 7,79% para 8,10%. Portanto, verifica-se que há uma melhora dos parâmetros clínicos periodontais em ambos os grupos, contudo não se verificou uma diferença significativa entre eles. Não obstante, o FMSRP promove um efeito benéfico em relação à condição de saúde periodontal, melhora dos parâmetros clínicos periodontais, em curto prazo (3 meses) tanto em indivíduos diabéticos como em não diabéticos, não sendo possível observar um melhor quadro glicêmico nos diabéticos

Periodontal disease is an inflammatory condition of infectious nature characterized by destruction of protecting and supporting dental tissues. It happens as a response produced by the host when attacked by microorganisms. Several factors are involved in this process. Among them, cytokines are key regulatory molecules in this immune response, playing a role either protective and/or destructive in lesion progression. Thus, this study investigated the immunohistochemical expression of IFN- , GATA-3, IL-17, IL-23, IL-6 and TGF- in gingival tissues of humans, in an attempt to gain a better understanding of the participation of Th1, Th2 and Th17 immune responses in the development of periodontal disease processes. To this end, eighty-two samples of gingival tissues were divided into three groups: Group 1 = 15 (samples of healthy gum tissue as controls), Group 2 = 36 (samples with chronic gingivitis) and Group 3 = 31 (samples with chronic periodontitis). All cases were submitted to morphological analysis from sections stained with hematoxylin and eosin and then subjected to staining by immunohistochemistry using the streptavidin-biotin method. Results showed positive labeling for all proteins. Nonetheless, we observed a greater expression of Th1 cytokines and Th17 cells in group 3. We found statistically significant difference between TGF- expression and the clinical condition of the samples (p=0.02). We conclude that Th1 and Th17 responses may act synergistically in the destructive process of periodontal tissue, overlapping the Th2 response that was also present in these tissues

Although photodynamic therapy have been used as a useful tool over the past 30 years in oncology, few clinical trials have been conducted in dentistry. Photodynamic therapy (PDT) uses non - toxic photosensitizers and selective which are administered in target cells followed by local application of visible light, producing reactive oxygen species capable of causing cell death by apoptosis or necrosis, injured the local vasculature, and exert important effects on the im mune system. New generations of photosensitizing agents, such as nanoparticulate phthalocyanines, has shown excellent results in antitumor and antibacterial activity . In this context, the present work constitutes the first clinical protocol of local appli cation of nanoemulsion chloro - aluminum phthalocyanine (AlClFc) followed by irradiation in human gingiva, and analyzed descriptively and comparatively , by means of immunohistochemistry , the expression of RANK , RANKL , OPG and VEGF in a split - mouth model . Eight healthy volunteers with clinical indication for extraction were included in the study . Seven days before the extraction, was injected in the gingiva of participants, 5 μ M of nanoemulsion AlClFc followed by irra diation with diode laser (660nm , 7 J/cm2 ), the contralateral side was used as control. Tissue specimens were removed seven days after the TFD is performed. Tissues sample were divided into two groups (test and con trol groups) for histological and immunohistochemical analysis. Patients were monitored at days, 0, 7, 14 and 30 to assess adverse effects of the therapy. Vascular alterations were seen in gingival samples that received PDT. Areas of edema and vascular con gestion, and intense vascularization were viewed . Additionally, dystrophic calcification in subepithelial region were observed in the test group. The results showed a similar pattern of immunostaining scores of RANK, RANKL and VEGF between the test and co ntrol groups, with no statistically significant difference (p = 0.317, p = 0.777, p = 0 .814, respectively). RANK and RANKL exhibited weak or absent immunostaining in most specimens analyzed. There was n o immunostaining for OPG. VEGF showed moderate to stro ng immunostaining in specimens from the test group. In addition, the clinical study showed that therapy was well tolerated by all patients. Adverse effects were short - time and completely reversible. Taken together, the results presented in this study showe d that PDT mediated by nanoemulsion containing AlClPc is safe for clinical application in gingival tissue and suggests that a strong immunostaining for VEGF after therapy .

OBJECTIVE: to identify a profile of the main causes of inappropriate referrals from primary care to specialized services, as strategy for the curriculum development of core competencies related to maternal health. METHODS: a cross-sectional study was performed using document analysis of all referrals of pregnant women from primary care to the high-risk pregnancy service, state of Rio Grande do Norte, Brazil. All pregnant women referred from June to December 2014 (n = 771) were included. According to their causes the referrals were categorized as adequate, inadequate or inconclusive. RESULTS: a total of 188 referrals were classified as inadequate (24.4%) and 93 inconclusive (12.1%) totalizing 36.5% of inappropriate referrals. The main causes identified in these inappropriate referrals were: low-risk pregnancy (12.8%), unconfirmed hypertension (12.1%), risk of abortion (8.9%), teenage pregnancy (7.1%) , toxoplasmosis (5.3%), Rh incompatibility (4.6%) and urinary tract infection (4.3%). These data contributed to the formulation of the following products: 1) a continuing education program for health professionals working in primary care, undergraduate students and residents; and 2) development of a virtual platform to support professionals who need to refer patients to high-risk pregnancy service. CONCLUSION: the results of this study are relevant in the current context of education of health professionals, with potential for positively impact not only in the development of skills related to maternal health in undergraduate and graduate education, as well as contributing for improvement of the health care of the population.

benign epithelial odontogenic lesions are great clinical importance entities that develop in the jaws from the tissues that form teeth. It has been shown that in benign and malignant tumors, are present in a large number of tumor stem cells, which has great implications in the development of these lesions. Oct-4 and CD44 have been demos as important markers for tumoral stem cells. The objective of this study was to identify epithelial cells expressing stem cell markers by immunohistochemical expression of Oct-4 and CD44 in a series of cases of benign epithelial odontogenic lesions. The sample was comprised of 20 cases of odontogenic keratocyst (OKC), 20 cases of solid/multicystic ameloblastoma and 20 cases of adenomatoid odontogenic tumor (AOT). The expression of Oct-4 and CD44 was evaluated in epithelial lesions using the percentage of positive cells (PP) and the intensity of expression (IE), being realized the sum of these scores, resulting in Total Immunostaining Score (TIS) ranging 0 to 7. The results were submitted to the appropriate statistical test (nonparametric Kruskal-Wallis and Spearman correlation coefficient). All cases were positive for both markers and most showed high expression of both markers. The analysis of Oct-4 expression revealed no statistically significant differences (p = 0.406) among the studied lesions. Regarding the CD44 expression, there was a statistically significant difference between the cases of ameloblastoma and TOA in relation to the CCO, with the latter show more cases in the score 7 (p = 0.034). In the correlation analysis of the immunoreactivity of both markers in the three lesions studied, there was no statistically significant correlation. The results of this study identified the presence of cells with stemness characteristics arranged at various sites in the epithelial component of the studied lesions suggesting their possible role in the histogenesis and differentiation in benign epithelial odontogenic lesions, thus contributing to the development of these lesions.

There is a bidirectional association between periodontal disease (PD) and diabetes mellitus, in which diabetes favors the development of PD and PD, if left untreated, can worsen the metabolic control of diabetes. Thus, periodontal disease should be treated to restore periodontal health and reduce the complications of diabetes. Therefore, the objective is assess the effect of full mouth periodontal therapy decontamination (Full Mouth Desinfection - FMD) in diabetic type II patients with chronic periodontitis during 12 months. Thirty-one patients in group one (G1) and 12 in group two (G2) were followed at baseline, 03, 06 09 and 12 months. There following clinical parameters were accessed: probing on bleeding (BOP), visible plaque index (PI), probing depth (PD), clinical attachment level (CAL) and gingival recession (GR). For diabetic patients, there were also made laboratory tests to evaluate blood parameters: fasting glucose and glycated hemoglobin. The results had been analyzed in two ways: all sites in the mouth and another with diseased sites. The Mann-Whitney, Friedman and Wilcoxon tests were used with 5% significance. Intergroup analysis of all sites it is clear that there was no significant difference over time concerning PD, BOP, PI, CAL and RG. However, when evaluating the diseased sites, we observed significant difference for CAL and PD, with higher values in G1. The intragroup analysis for all sites showed a statistically significant reduction at PD, PI and BOP in both groups. Intragroup analysis of periodontal affected sites showed a statistically significant reduction in PD, BOP and CAL in both groups. There was also a statistically significant increase in RG values. There was no significant change concerning glycated hemoglobin and fasting glucose in the G1. Therefore, it can be concluded that there were improvements in periodontal parameters over the 12 months of research, but without changes in glycemic levels of diabetic patients. Thus, periodontal therapy proved effective in maintaining oral health.
