Para tanto, foram avaliadas duas condições estressantes: Estudo I - prova; Estudo II - tensão pré-menstrual (TPM). O Estudo I foi composto de 2 grupos: A e B. O grupo A (34 voluntários), foi subdividido em 18 voluntários com estresse e 16 voluntários sem estresse. As concentrações dos CSV e foram medidas 1 semana antes da prova, no dia e 1 semana após, através do monitor de sulfetos (Halimeter) e o fluxo salivar também foi mensurado. No grupo B (37 voluntários), além dessas análises foram mensurados o pH, "capacidade tampão", cálcio, fósforo e proteína na saliva. O Estudo II foi composto por 50 voluntárias: 27 mulheres sem TPM (controle) e 23 mulheres com TPM. As mensurações dos CSV e do fluxo salivar foram realizadas nos períodos não-menstrual, pré-menstrual e de menstruação. A análise estatística mostrou que tanto no Grupo A (n=34) quanto no Grupo B (n=37) a concentração dos CSV no dia da prova foi maior (p<0,05) enquanto que a taxa de fluxo salivar foi menor (p<0,05). Os voluntários com estresse (n=18) e sem estresse (n=16) também apresentaram maiores concentrações de CSV no dia da prova (p<0,05), enquanto o fluxo salivar foi menor somente nos voluntários não estressados (p<0,05). A análise bioquímica da saliva do Grupo B revelou - que o pH foi menor no dia da prova (p<0,05), e as demais análises não foram diferentes (p>0,05). No Estudo II, as voluntárias sem TPM (n=26) apresentaram maior concentração dos CSV no período menstrual (p<0,05). Enquanto nas voluntárias com TPM (n=23) a concentração dos CSV foi maior (p<0,05) nos períodos menstrual e pré-menstrual. Já o fluxo salivar não mostrou diferenças (p>0,05). Os resultados sugerem que o estresse é um fator pré-disponente da halitose, cujo mecanismo não pode ser explicado somente pela diminuição do fluxo salivar / Abstract:The aim of study was to evaluate the relationship between stress and volatile sulfur compounds (VSC) present in mouth air. Thus, two stressfull conditions were evaluated: Study 1- examination; Study II - premenstrual syndrome (PMS). Study I was composed of 2 groups: A and B. Group A (34 volunteers), was divided in 18 volunteers with stress and 16 volunteers without stress. VSC concentrations were measured a week before, on day and a week after the exam using a sulfide monitor (Halimeter) and the salivary flow was measured. In group B (37 volunteers), others analyisis as pH, "buffer capacity", proteins, calcium and phosphorus, in saliva were performed. In study II, fifty women were selected: 27 women without PMS symptoms (control group) and 23 women with PMS symptoms. The measurements were performed during non-menstrual, PMS and menstrual periods. The statistical results showed in both groups A and B an increase of VSC concentration on the exam day (p<0.05) and the salivary flow was lower (p<0.05). Volunteers with stress (n=18) and without stress (n=16), presented higher VSC concentration on the exam (p<0.05), but there was statistical diferences in the salivary flow rate only in the volunteers without stress (p<0.05). The biochemistry analisys of the saliva in group B showed that pH was lower on the exam day (p<0.05), and others analisys were not statistical differences (p>0.05). In study II, the volunteers without PMS symptoms (n=26) presented higher VSC concentration in the menstrual period (p<0.05). Volunteers with PMS (h=23) showed a greater VSC concentration in both menstrual and PMS periods (p<0.05). Salivary flow rate was not statistically different (p>0.05). The results suggest that stressful conditions can be a predisposing factor for bad breath, and the mechanism cannot be explained only by the decrease of the salivary flow / Mestrado / Fisiologia Oral / Mestre em Odontologia

<p>The aim of this study is to examine the knowledge and experience of the bad breath among high school students in Kristianstad. A further objective was to measure the amount of VSC (Volatile Sulfur Compounds) among those who perceive themselves to have a bad breath. A questionnaire with 21 closed questions was distributed to 120 high school students from Kristianstad municipality who were between the ages of 17-20. The results of this study revealed that most of the students had good knowledge of halitosis. The majority of all participants thought it was important to smell fresh in the mouth and also experienced most of their breath as very good or good. Only a few felt that they had bad breath. However, these persons did think their breath affect their everyday life. Furthermore, they have never felt embarrassed or caught in embarrassing situations due to their breath. The results from the clinical examination was carried out on 8 of the 120 students and was designed to measure the amount of sulphurous gases in the oral cavity which revealed that the average values that emerged in the examination below is the limited values for having a poor breath.</p> / <p>Syftet med denna studie var att undersöka kunskapen och upplevelsen av dålig andedräkt hos gymnasieelever i Kristianstad, ytterligare ett syfte var att mäta mängden VSC (reaktiva svavelföreningar)  hos dem som upplever sig ha dålig andedräkt. En enkät med 21 slutna frågor delades ut till 120 gymnasieelever som var mellan 17-20 år och studerade i Kristanstads kommun. Av resultatet i denna studie framkom att de flesta av gymnasieeleverna hade goda kunskaper om halitosis. Nästan alla 120 som besvarade enkäten tyckte att det var viktigt att lukta fräsch i munnen och dessutom upplevde de flesta sin andedräkt som mycket bra eller bra. Endast ett fåtal (14% ) kände att de ibland hade dålig andedräkt. Hos dessa  påverkades inte andedräkten deras vardagliga liv och de hade aldrig blivit generade eller hamnat i pinsamma situationer på grund av sin andedräkt. Resultatet från den kliniska undersökningen som gjordes på 8 av de 120 elever som besvarade enkäten där mängden av de svavelhaltiga gaserna i munhålan mättes visade att i genomsnitt ligger värden som framkom i undersökningen under gränsvärden för att man skall ha dålig andedräkt.</p>
