Kunskap om svavelhalter i den svenska berggrunden är viktig när bergmassa ska losshållas och bearbetas, oavsett om det gäller gruvbrytning, infrastruktur eller andra byggnationer. Svavel förekommer ofta bundet i sulfider som oxiderar i kontakt med syre och vatten, vilket kan ha en försurande effekt på yt- och grundvatten. Sulfidförande berg har tidigare kartlagts mestadels i samband med malmprospektering och gruvbrytning. Det finns ganska omfattande svaveldata från norra Sverige, men det saknas tillräckligt med svavelmätningar i Stockholmsområdet för att dra några tydliga slutsatser om vart de förhöjda och potentiellt skadliga halterna av sulfider kan påträffas. Kandidatarbetet har utförts i samarbete med avdelningen för geologi och bergteknik på WSP i Stockholm, i syfte att få en bättre förståelse av vilka bergarter i Stockholmsområdet som kan förväntas inneha förhöjda halter av svavel och vart dessa bergarter kan förväntas påträffas. Under projektet har 329 prover av olika litologier samlats in och undersökts. Litologierna har kategoriserats till 7 förenklade bergartsgrupper. Proverna har skickats på geokemisk analys där olika metoder använts för att bland annat bestämma den totala svavelhalten hos bergarten. Vid halter över 1000 ppm har ytterligare analyser utförts med acid base accounting [ABA] samt net acid generation [NAG]. Dessa tester beskrivs i rapporten och används för att ta reda på om bergarten har försurande egenskaper. Bergartprovlokalerna har digitaliserats som punkter i geopackages i kartprogrammet QGIS. Punkterna för proverna har sammanförts med en digitaliserad version av Stålhös (1968) detaljerade geologiska karta över Stockholms berggrund. Svavelhalten i varje enskild stuff har kopplats till en yta från den sedimentära gnejsen, uppdelad enligt Stålhös (1968). Den producerade kartan har analyserats i QGIS för att ta fram geologiska och bergartskopplade trender av svavelhalten i Stockholms berggrund. 7 olika symmetriska histogram, så kallade fioldiagram, som visar svavelhalten och den relativa provdensiteten i respektive bergartskategori har tagits fram i rapporten. Slutligen har amfibolit och sedimentär gnejs, med underkategorin granatådergnejs identifierats som bergarterna med högst risk att innehålla förhöjda svavelvärden i Stockholmsområdets berggrund. / Knowledge of sulfur levels in the Swedish bedrock is important when rock mass is to be detached and processed in any way, whether it concerns mining, infrastructure, or other constructions. Sulfur is often found bound in sulfides that oxidize in contact with oxygen and water, which can have an acidifying effect on surface- and groundwater. Sulfide-bearing rock has previously been mapped mostly in connection with ore exploration and mining. There is quite extensive sulfur data from northern Sweden, but there are not enough Sulphur measurements in the Stockholm area to draw any clear conclusions about where the elevated and potentially harmful levels of sulfides can be found. The bachelor's thesis has been carried out in collaboration with the Division of Geology and Rock Engineering at WSP in Stockholm, with the aim of gaining a better understanding of which rocks in the Stockholm area can be expected to possess elevated levels of sulfur and where these rocks can be expected to be found. During the project, 329 samples of different lithologies have been collected and examined. The lithologies have been categorized into 7 simplified rock categories. The samples have been sent for geochemical analysis where different methods have been used to determine, among other things, the total sulfur content of the rock. At concentrations above 1000 ppm, further analyses have been performed using acid base accounting [ABA] and net acid generation [NAG]. These tests are described in the report and are used to find out if the rock has acidifying properties. The rock test premises have been digitized as points in geopackages in the QGIS mapping program. The points for the samples have been combined with a digitized version of Stålhös (1968) detailed geological map of Stockholm's bedrock. The sulfur content of each individual sample has been linked to an area from the sedimentary gneiss, divided according to Stålhös (1968). The produced map has been analyzed in QGIS to produce geological and rock-linked trends of the sulfur content in Stockholm's bedrock. 7 different violin graphs showing the sulfur content and relative sample density in each rock category have been produced in the report. Finally, amphibolite and sedimentary gneiss, with the subcategory of garnet vein gneiss, have been identified as the rocks with the highest risk of containing elevated sulfur values in the Stockholm bedrock area.

The literature was reviewed in the first manuscript, emphasizing BMS characteristics, etiology and therapeutics. Low-level laser therapy (LLLT) has been widely used in oral disorders because of its analgesic, anti-inflammatory and tissue repair effects. Thereby, in the second manuscript we reviewed the applicability and protocols of LLLT in the management of lichen planus, xerostomia, recurrent aphthous stomatitis, herpes labialis, oral mucositis and BMS. Controlled trials investigating the effects of LLLT on BMS are still rare. The present randomized, placebo-controlled study aimed to clinically assess the effect of LLLT in the treatment of patients with BMS, and to investigate the impact of such therapy in the quality of life of these individuals. The sample consisted of 78 BMS patients who were randomly assigned into three laser groups and one control group (n=19), which was treated with sham LLLT. Laser groups were treated with the following parameters: IR1w group, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, weekly LLLT sessions, ten sessions); IR3w group, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, three weekly LLLT sessions, nine sessions); red laser group, n=19 (685 nm, 35 mW, 2 J, 72 J/cm2, 58 s, three weekly LLLT sessions, nine sessions). Symptoms were assessed at initial, at the end of the treatment and eight weeks later using visual analogue scale and visual numeric scale. Quality of life related to oral health was assessed through the Oral Health Impact Profile (OHIP-14). Statistical analysis was carried out using repeated measures ANOVA followed by the Tukey test. There was a significant reduction in the symptoms in all groups at the end of the treatment, which was maintained in the follow-up. The scores of the IR1w and IR3w laser groups were significantly lower in comparision to the control group. On the other hand, there was no significant difference between Red laser group and control group. There was also a decrease in the OHIP-14 scores in the four groups. The scores of the IR3w laser group differed significantly from those of the control group, showing that LLLT had a positive impact on the quality of life related to oral health. Based on the results of this study it is possible to conclude that infrared LLLT, in the parameters used, reduces the BMS symptoms and can be an alternative therapeutic for this disorder. / A s?ndrome da ard?ncia bucal (SAB) ? uma doen?a de etiopatogenia desconhecida, caracterizada pela sensa??o de queima??o e ard?ncia na mucosa bucal, que se apresenta clinicamente normal. No primeiro artigo desta tese foi realizada uma revis?o da literatura com ?nfase nas caracter?sticas da SAB, etiologia e terap?utica. Uma vez que a terapia laser de baixa pot?ncia (LLLT) tem sido amplamente utilizada em enfermidades bucais devido aos seus efeitos analg?sicos, biomoduladores e antiinflamat?rios, no segundo artigo foram revisados a aplicabilidade e os protocolos da LLLT no manejo do l?quen plano, xerostomia, ulcera??o aftosa recorrente, herpes labial, mucosite e SAB. Ensaios cl?nicos controlados investigando o efeito da LLLT na SAB s?o ainda escassos; portanto, o presente estudo cl?nico randomizado e controlado teve como objetivos avaliar o efeito da LLLT nos sintomas da SAB, bem como, o impacto desta terapia na qualidade de vida relacionada ? sa?de bucal dos pacientes. A amostra foi constitu?da por 78 pacientes com SAB, distribu?dos em tr?s grupos laser e um grupo-controle (n=19), no qual foi empregada sham LLLT. Os seguintes protocolos de LLLT foram empregados nos grupos-laser: grupo IR1w, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, uma sess?o semanal, total de 10 sess?es); IR3w, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, tr?s sess?es por semana, total de nove sess?es); laser vermelho, n=19 (685 nm, 35 mW, 2 J, 72 J/cm2, 58 s, tr?s sess?es por semana, total de nove sess?es). Os sintomas foram avaliados por meio de escala visual num?rica e escala visual anal?gica no in?cio e fim do tratamento, e oito semanas ap?s. Para avalia??o da qualidade de vida relacionada ? sa?de bucal foi usado o instrumento Oral Health Impact Profile (OHIP- 14). Os dados foram analisados por meio do teste ANOVA de medidas repetidas, seguido pelo teste de Tukey. Houve redu??o significativa dos sintomas ao final do tratamento em todos os grupos, o que se manteve no acompanhamento de oito semanas. Os escores dos grupos laser IR1w e IR3w foram significativamente inferiores aos do grupo-controle. Por outro lado, n?o houve diferen?a significativa entre o grupo laser vermelho e o grupo-controle. Houve tamb?m redu??o significativa nos escores do OHIP-14 nos quatro grupos, entretanto, somente o grupo laser IR3w apresentou diferen?a significativa em rela??o ao grupo-controle, mostrando que o tratamento teve impacto positivo na qualidade de vida relacionada ? sa?de bucal. Com base nos resultados, pode-se concluir que a LLLT no comprimento de onda infravermelho e nos par?metros utilizados neste estudo, reduz os sintomas da SAB e pode ser uma alternativa terap?utica no tratamento desta doen?a.

Embora haja evid?ncias para uma origem neurop?tica, outros fatores parecem estar envolvidos na etiologia da SAB, como a associa??o de transtornos psicol?gicos e altera??es hormonais. Com o objetivo de identificar fatores de risco para a s?ndrome, neste estudo foram analisadas as concentra??es salivares de desidroepiandrosterona (DHEA), a velocidade do fluxo salivar (VFS) e os escores de depress?o e desesperan?a de pacientes com essa doen?a. Foram selecionadas 30 pacientes do sexo feminino portadoras de SAB, com idade variando entre 42 a 81 anos, e 30 pacientes-controle do mesmo sexo e faixa et?ria, que n?o apresentassem les?es bucais nem utilizassem f?rmacos ansiol?ticos, antidepressivos ou corticoster?ides. Ap?s anamnese e exame f?sico, a VFS foi determinada em repouso e sob estimula??o e os sintomas de depress?o e de desesperan?a foram investigados pelos instrumentos The Beck Depression Inventory e The Beck Hopelessness Scale, respectivamente. Amostras de saliva foram coletadas pela manh? e ? noite para an?lise da DHEA pela t?cnica de radioimunoensaio. O grupocaso exibiu sintomas de disgeusia e de xerostomia numa freq??ncia significativamente superior ao controle (p=0,045 e p=0,003, respectivamente). A velocidade do fluxo salivar das pacientes com SAB foi inferior ? do grupo-controle, tanto em repouso, quanto sob estimula??o (p<0,001 e p=0,007, respectivamente). N?o houve diferen?a significativa entre os grupos quanto aos escores de desesperan?a (p=0,597) ou de depress?o (p=0,416). O grupo-caso obteve concentra??es salivares de DHEA significativamente inferiores ao controle nas amostras matinais (p=0,003), entretanto, nas amostras coletadas ? noite, n?o houve diferen?a entre os grupos (p=0,620). N?o foi observada correla??o entre as concentra??es salivares de DHEA e os escores de depress?o e de desesperan?a nas pacientes com SAB. A an?lise multivariada de regress?o log?stica demonstrou que a velocidade do fluxo salivar em repouso e as concentra??es salivares matinais de DHEA foram fatores associados ? SAB. Os resultados do presente estudo permitem concluir que: (1) pacientes com SAB exibem concentra??es salivares matinais de DHEA e VFS inferiores ?s de pacientes sem a doen?a; (2) os sintomas de depress?o e desesperan?a n?o diferem entre indiv?duos com a s?ndrome e os controle; (3) n?o h? correla??o entre as concentra??es salivares de DHEA e os escores de depress?o e desesperan?a em indiv?duos com a S?ndrome da Ard?ncia Bucal. Sendo este o primeiro estudo a investigar as concentra??es salivares de DHEA em pacientes com SAB, sugerem-se outras pesquisas para esclarecer esta associa??o e suas conseq??ncias.

Estudos t?m demonstrado que o fitoter?pico Catuama? , composto por quatro extratos de plantas medicinais (Paullinia cupana, Trichilia catigua, Zingiber officinalis e Ptychopetalum olacoides), possui a??o vasorelaxante, antinociceptiva e antidepressiva. Este estudo cl?nico, randomizado, duplo-cego, placebo-controlado objetivou avaliar clinicamente, por meio de escala visual num?rica (EVN) e escala de faces (EF), o efeito do uso sist?mico da Catuama? na sintomatologia da SAB. A amostra foi constitu?da por 72 pacientes com a doen?a, que foram distribu?dos aleatoriamente em grupos experimental (n=38) e controle (n=34). Foram inclu?dos pacientes com idade m?nima de 40 anos que relatassem sintomas de ard?ncia, queima??o ou dor na mucosa bucal, com no m?nimo seis meses de dura??o e sem les?es bucais ao exame f?sico. Exclu?ram-se indiv?duos que estivessem utilizando f?rmacos antidepressivos, ansiol?ticos ou anticonvulsivantes, pacientes com hipossaliva??o, altera??es no hemograma, nas concentra??es s?ricas de glicose, ferro, ?cido f?lico e vitamina B12. Os pacientes foram orientados a ingerir duas c?psulas ao dia, antes do almo?o e do jantar, durante oito semanas e foram reavaliados ap?s 4, 8 e 12 semanas do in?cio do experimento. Sessenta indiv?duos conclu?ram o estudo. Embora ambos os grupos tenham demonstrado redu??o da sintomatologia, a melhora obtida pelo grupo experimental foi significativamente superior ? do grupocontrole ap?s 4 (EF, p=0.010) e 8 (EVN, p=0.003; EF, p<0.001) semanas de uso da Catuama?. Ap?s 12 semanas de acompanhamento, isto ?, 30 dias ap?s o t?rmino do tratamento, os pacientes com a s?ndrome apresentaram redu??o de 51,3% na sintomatologia, enquanto no grupo-controle este valor foi de 18,8% (EVN, p=0.001). Baseados nos achados do presente estudo, conclui-se que a administra??o sist?mica da Catuama? reduz os sintomas da SAB e pode ser uma alternativa terap?utica, com menos efeitos adversos quando comparada ?s drogas comumente utilizadas no tratamento dessa doen?a

Os tratamentos foram os materiais utilizados para a confec??o das celas maternidade, sendo os tratamentos alvenaria e ard?sia. Foram monitoradas seis celas maternidade em cada tratamento, observando-se 12 matrizes e suas respectivas leitegadas (139 leit?es), sendo mensuradas a temperatura de globo negro, temperatura de bulbo seco e umidade relativa no interior de cada cela, a velocidade do vento e o n?vel de ru?dos no interior da instala??o. Os dados do ambiente t?rmico nos dias de avalia??o comportamental foram coletados ?s 09h e 15h e os dados do ambiente ac?stico e t?rmico nos dias de avalia??o ambiental foram coletados com intervalo de 60 minutos, com in?cio ?s 07h30 e t?rmino ?s 16h. Foram calculados os ?ndices de temperatura de globo e umidade e carga t?rmica radiante. Foi avaliada tamb?m a temperatura da superf?cie corporal de matrizes e leit?es ?s 09h e 15h, nos dias de avalia??o ambiental. Os dados foram submetidos a um esquema de parcelas subdivididas, no qual as parcelas eram os tratamentos e as subparcelas os hor?rios. O estudo do repert?rio comportamental de ambos os tratamentos realizou-se por meio do uso de etogramas espec?ficos com avalia??o de imagens digitais captadas a intervalo de quinze minutos. Os resultados foram digitalizados em planilha eletr?nica para confec??o de etogramas de frequ?ncia das atividades pr?-determinadas. O desempenho dos leit?es foi avaliado com pesagens ao nascimento e ao desmame. Baseando-se nos dados ambientais obtidos, observou-se diferen?a significativa para todas as vari?veis observadas, exceto para a carga t?rmica radiante e temperatura da superf?cie corporal de matrizes. O tratamento alvenaria apresentou, de forma geral, melhores resultados; entretanto, nenhum dos tratamentos mostrou-se ideal ?s matrizes e aos leit?es. No per?odo da manh? observou-se condi??es ambientais mais pr?ximas ao conforto das matrizes e durante a tarde o ambiente foi mais confort?vel para os leit?es. Avaliando os n?veis de ru?dos emitidos, sup?e-se que o bem-estar dos su?nos foi maior na instala??o de alvenaria. Os leit?es que se encontravam nas celas de alvenaria passaram menos tempo mamando (25,62%) e mais tempo no escamoteador (38,91%) quando comparado ?queles mantidos nas celas confeccionadas em ard?sia (29,22% mamando e 24,90% no escamoteador). O fato de os leit?es mantidos em celas de ard?sia permanecerem mais tempo mamando promoveu ligeiro aumento, n?o significativo, no ganho de peso deles. Os animais mantidos em celas de ard?sia apresentaram melhora de 1,9% em rela??o ao manual da linhagem comercial utilizada, comportamento n?o observado naqueles mantidos em celas de alvenaria, que apresentaram desempenho de acordo com o manual. Os materiais utilizados na constru??o das celas n?o influenciaram o repert?rio comportamental das matrizes que permaneceram a maior parte do tempo deitadas (67,80% e 72,89%, respectivamente para alvenaria e ard?sia). A partir dos resultados encontrados, a ard?sia apresentou piores resultados quanto ? influ?ncia do material de constru??o sobre o ambiente, quando comparados ? alvenaria; entretanto, observou-se melhor desempenho dos leit?es que se encontravam alojados nas celas confeccionadas em ard?sia. Mediante os resultados obtidos, pode-se concluir que, a escolha do material de constru??o deve ser feita com base na economicidade oferecida por ele; entretanto, al?m do melhor desempenho dos leit?es, a ard?sia apresenta maior facilidade de limpeza e desinfec??o, por ser um material menos poroso e mais imperme?vel que alvenaria. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, [2010]. / ABSTRACT In order to evaluate thermal/acoustic environment and behavioral aspects in different housing constructions, a study analyzing an alternative material to build pens was carried out in a maternity located in Papagaio-MG. Treatments were masonry and slate, the materials used to build pens. In each treatment, six cages were monitored, being observed 12 sows and their respective litter (139 piglets). Temperatures at black globe and dry bulb, relative humidity inside cage, wind velocity and noise levels inside housing were measured. Thermal environment data at days of behavior evaluation were collected at 9:00 and 15:00, and data of acoustic and thermal environment were collected at intervals of 60 minutes, from 07:30 to 16:00. Globe temperature and humidity indexes and radiant thermal load were calculated. Body surface temperature of sows and piglets were evaluated at 09:00 and 15:00 during environmental evaluation. Data was under a split plot scheme, where treatments were splits and plots were the hours. Behavioral repertoires of both treatments were studied by using specific ethograms and evaluating digital images caught each 15 minutes. Piglets were weighted at birth and weaning in order to evaluate their performance. According to environmental data, it was observed significant difference for all variables observed, except to radiant thermal load and body surface temperature of sows. Masonry treatment showed better results, however, both treatments were not classified as ideal to sows and piglets. Morning period showed more comfortable environmental conditions to sows, while afternoon period was to piglets. Cause of noise level swine was better in masonry housing. Piglets in masonry housing spent little time sucking and higher time in the creep. On the other hand, they spent higher time sucking, when in slate housing. Animals in slate housing were 1, 2% better in relation to the manual of commercial line. Behavioral repertoire of sows was not influenced by the material used to build pens. Results show that slate was environmentally worse than masonry; however piglets showed better performance when in slate housing. To choose the material of construction it is important to think about economy, however, besides a better piglet performance, slates are better to clean and disinfect.

Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. The drainage quality depends mainly on the mineralogical and chemical composition of the extractive wastes, and especially on the ratio of acid-producing and neutralizing minerals, combined with reactions catalysed by microbes. Since harmful drainages play a major role in the generation of environmental issues for extractive industry, the accurate prediction of the drainage quality is of utmost importance. To design appropriate extractive waste facilities and drainage management, the characterisation of extractive wastes and assessment of the behaviour of the waste material is essential already before the actual mining activities start. Several methods have been developed to characterize extractive waste materials and to predict their short and long term behaviour, including e.g. geochemical laboratory tests, static tests and longer term kinetic tests, and geochemical modelling. The characterisation methods for assessing the ARD risk can be divided into static and kinetic tests. Static tests are short term laboratory analyses, usually used for preliminary investigation and screening. Kinetic tests are longer term tests, revealing information on the time scale of drainage events. Commonly used static tests for ARD prediction include acid–base accounting (ABA) tests and the net acid generation (NAG) test. Since acid and neutralisation potential largely depend on the ratio and quality of acid-producing and neutralizing minerals, mineralogical calculations could also be used for ARD prediction. The mobility of potentially harmful substances from extractive waste can be preliminary assessed using different geochemical laboratory tests, including selective extraction and leaching methods. The most commonly used selective extraction method in Finland is the aqua regia (AR) extraction. In addition to some silicates and secondary precipitate minerals, it is intended to dissolve elements bound especially to sulphide phases. A less commonly used method for element mobility prediction is the analysis of the single addition NAG test leachate. In this study, several Finnish waste rock sites were investigated and the performances of different preliminary drainage quality test methods evaluated and compared. The assessed acid production potential methods included the ABA test as presented in the standard EN 15875, the single addition NAG test as presented in the AMIRA guidebook, and a SEM mineralogy-based calculation. The assessed methods for element mobility prediction included the single addition NAG test leachate analysis and the AR extraction. According to the results, pyrrhotite seems to be the main mineral contributing to acid production, and the silicate minerals the main contributors to the neutralisation potential at the most Finnish waste rock sites. Since silicate minerals appear to have a significant role in ARD prevention, the behaviour of these minerals in mining environment should be more thoroughly investigated. In the investigated Finnish waste rocks, Co, Cr, Cu and Ni often occurred as elevated concentrations, and the most widely abundant harmful elements in the waste rock drainages were Co, Cu, Ni and Zn. The results suggest that an acid production prediction based on SEM mineralogical calculation is at least as accurate as the commonly used static laboratory methods. The AR extraction indicates well which elements might occur as elevated concentrations in the drainage. Also the NAG test leachate analysis performed well in element mobility assessment, but only when the NAG test leachate was sufficiently acidic, the leachate pH being below of 3-6, depending on the element of interest.

During the accession period EU has the opportunity to influence a future member state in various political areas. Is gender equality politics one of them? The purpose of this thesis is to explore EUs role in promoting gender equality in Croatia, the latest member who entered 1 July 2013. The theoretical framework consist of two theories, new institutionalism and radical feminism. New institutionalism helps us analyse the tools EU has in order to influence an accession country by dividing them into two themes. Institutions and interest. The theory of radical feminism makes the analyse deeper by deciding the quality of EUs impact on gender equality. The result shows that EU has done a sufficient work making sure Croatia implemented gender equality laws but the laws does not cover all political areas why the overall quality of EUs influence over a member state can be questioned.

A sua etiologia ? desconhecida, entretanto, fatores psicol?gicos, como o estresse e a ansiedade, s?o apontados como poss?veis agentes etiol?gicos. O cortisol, tamb?m conhecido como hidrocortisona, ? o principal horm?nio na modula??o do sistema de estresse, e a sua associa??o com esta s?ndrome nunca foi realizada. O objetivo do presente trabalho foi avaliar os n?veis de cortisol, estresse e ansiedade de pacientes portadores de s?ndrome de ard?ncia bucal (SAB). Foi realizado um estudo caso-controle com uma amostra constitu?da por 60 pessoas divididas em: grupo de pacientes portadores de SAB, e grupo controle. Foram realizados em todos os pacientes a anamnese, o exame f?sico, sialometria, aplica??o dos invent?rios de estresse de Lipp e de ansiedade de Beck, assim como coleta de saliva durante 3 per?odos diferentes do dia para an?lise do cortisol salivar. A an?lise dos resultados mostrou que no grupo SAB houve diferen?a estat?stica significativa no que diz respeito ? xerostomia, por?m, nenhum dos grupos apresentaram os fluxos salivares de repouso e estimulado reduzidos. N?o houve diferen?a quanto aos n?veis de ansiedade ou estresse, por?m os n?veis de cortisol salivar dos pacientes do grupo SAB foram estatisticamente maiores (p= 0,0008) quando comparados com o grupo controle. Tamb?m foi verificado que n?veis de cortisol salivar acima de 11,30nmol/L/h possuem um Odds Ratio de 4,0 [95%IC (1,37 - 11,70)]. Os resultados sugerem que os n?veis elevados de cortisol est?o associados ? presen?a da s?ndrome da ard?ncia bucal.
