Resumo Objetivos: Analisar a correlação do nível de halitose com qualidade de vida relacionada à saúde oral e investigar mudanças no nível de halitose após a reabilitação oral. Métodos: Um estudo observacional foi conduzido com uma amostra de 32 pacientes. Foram coletados dados sociodemográficos e sobre hábitos de higiene oral, realizado o exame periodontal, aplicado o questionário da OHIP-14 e realizado o teste organolético para avaliação do nível de halitose. A análise estatística incluiu o teste qui-quadrado, teste exato de Fisher e teste t. Adotou-se o nível de significância de 5%. Resultados: O grupo com halitose apresentou frequência maior de higiene oral insatisfatória do biofilme dental, baixa adesão ao uso do fio dentário e presença de biofilme lingual (p<0,001). Todos os pacientes com halitose apresentavam periodontite (p=0,026). Um maior impacto da saúde oral sobre a qualidade de vida foi detetado no Grupo Halitose (p=0,003). A análise comparativa antes e após a reabilitação oral mostrou redução significativa nos níveis de halitose (p=0,002). Conclusões: Indivíduos com halitose apresentam maior impacto negativo da saúde oral na qualidade de vida. A adoção de cuidados de higiene oral e planeamento adequado do tratamento dentário pode auxiliar no controle da halitose e contribuir para a melhoria da qualidade de vida.

Abstract Objectives: To analyze the correlation between the level of halitosis and oral health-related quality of life and investigate changes in the level of halitosis after oral rehabilitation. Methods: An observational study was conducted with a sample of 32 patients. Socio-demographic data and oral hygiene habits were recorded, a periodontal examination was performed, the OHIP-14 questionnaire was applied, and the organoleptic test was performed to assess the level of halitosis. The statistical analysis included the chi-square test, Fisher’s exact test, and the t-test. The level of significance was set at 5%. Results: The group with halitosis presented a higher frequency of unsatisfactory oral hygiene of the dental biofilm, low adherence to flossing, and presence of lingual biofilm (p<0.001). All patients with halitosis had periodontitis (p=0.026). A greater impact of oral health on quality of life was detected in the Halitosis Group (p =0.003). The comparative analysis before and after oral rehabilitation showed a significant reduction in halitosis levels (p=0.002). Conclusions: Oral health’s negative impact on quality of life is greater in individuals with halitosis. The adoption of oral hygiene care and proper planning of dental treatment can help control halitosis and contribute to improving quality of life.

Abstract: The systemic effect of chronic periodontitis (CP) has been suggested by several studies as an etiologic factor and modulator of diseases based on the changes in the inflammatory marker levels. This study aimed to investigate the relationship between the changes in clinical periodontal outcomes and serum biomarkers (CRP, IL-6, albumin and percentage of leukocytes) after non-surgical periodontal therapy in systemically healthy adults. An interventional study was conducted with a sample of 29 individuals without CP (control group) and 33 with CP (CP group). Periodontal clinical variables were recorded, and the serum levels of inflammatory markers were measured. Statistical analysis included the chi-square and Student’s t-tests and Pearson’s correlation analysis. After 90 days of non-surgical periodontal treatment, a reduction of periodontal parameters and IL-6 in both groups could be observed (P < 0.001). The correlation analysis revealed a directly proportional correlation between changes in the probing depth (r = 0.349, P = 0.049) and clinical attachment level (r = 0.374, P = 0.034) with CRP in the CP group. The findings suggest a reduction of IL-6 serum concentration and periodontal clinical measures 90 days after periodontal therapy in both groups.

Resumo Objetivo: Investigar a associação entre uso de chupeta e mamadeira e comportamentos desfavoráveis à amamentação durante as mamadas. Métodos: Um estudo transversal foi conduzido com 427 bebês/mães. Foram coletados dados sociodemográficos, perinatais e sobre o uso de bicos artificiais (chupeta e/ou mamadeira) através de questionário. Os aspectos de amamentação referentes à posição, afetividade, adequação da sucção, respostas do bebê e anatomia das mamas foram avaliados através da observação durante a mamada. O teste qui-quadrado e a análise de regressão linear múltipla foram usados para investigar associação entre as variáveis. Resultados: Os aspectos de amamentação que apresentaram percentuais mais elevados da categoria ruim foram a adequação da sucção (22,5%) e posição (22,2%). O grupo de bebês que usavam chupeta e/ou mamadeira apresentou percentuais mais elevados nas categorias ruim e regular quando comparados com a categoria bom para todos os cinco aspectos da amamentação avaliados (p < 0,001). A análise de regressão linear revelou que o incremento do número de comportamentos desfavoráveis referentes à posição, afetividade, adequação da sucção e respostas do bebê estavam associados de forma independente tanto ao uso de chupeta quanto ao uso de mamadeira (β positivo, p < 0,05), enquanto que anatomia das mamas estava associado de forma independente apenas com o uso de mamadeira. Conclusão: Os achados sugerem que o uso de chupeta e/ou mamadeira pode estar associado a comportamentos desfavoráveis durante amamentação, em especial o uso de mamadeira.

Abstract Objective: To investigate the association between pacifier use and bottle-feeding and unfavorable behaviors during breastfeeding. Method: A cross-sectional study was conducted with 427 babies/mothers. Socio-demographic, perinatal data, and information about the use of artificial nipples (pacifier and/or bottle) were collected through a questionnaire. The breastfeeding aspects regarding position, affectivity, sucking behavior, baby responses, and breast anatomy were evaluated through observation during breastfeeding. The chi-squared test and the multiple linear regression analysis were used to investigate the association between the variables. Results: The aspects of breastfeeding that showed higher percentages of the category "poor" were sucking behavior (22.5%) and position (22.2%). The group of infants who used pacifiers and/or bottle showed higher percentages in the poor and fair categories when compared with the good category for all five breastfeeding aspects evaluated (p < 0.001). The linear regression analysis revealed that the increase in the number of unfavorable behaviors regarding position, affectivity, sucking behavior, and baby responses were independently associated with both pacifier and bottle use (β positive, p < 0.05), while breast anatomy was independently associated only with bottle use. Conclusion: The findings suggest that the use of pacifiers and/or bottle-feeding may be associated with unfavorable behaviors during breastfeeding, especially the use of bottle-feeding.
