ABSTRACT
Resumo Enquadramento: O controlo do biofilme oral com anti-sépticos deve ser adequado aos protocolos elaborados para os doentes na unidade de terapia intensiva (UTI). Objetivo: Avaliar o efeito da solução de clorexidina 0,12% na redução de microrganismos na saliva de doentes de UTI. Metodologia: Estudo coorte com 45 voluntários divididos em: Clínica Médica (controlo, auto higiene oral), UTI não-entubado e UTI entubado. A higiene oral na UTI foi realizada com clorexidina. A análise microbiológica foi realizada com a contagem de microrganismos na saliva. A análise dos dados foi feita com ANOVA. Resultados: Houve uma redução dos microrganismos após higiene oral. O controlo apresentou diferença significativa com UTI entubado nos períodos imediato e após 30 min. Doentes entubados apresentaram redução dos microrganismos até 12 horas após higiene com clorexidina. Conclusão: A higiene com clorexidina reduz em até 12 horas os microrganismos bucais de doentes entubados. Estes resultados podem contribuir para elaboração de protocolos de higiene oral em UTI, além de sustentar estratégias como redução nos custos e efeitos colaterais associados à clorexidina.
Abstract Background: The control of oral biofilm with antiseptics should follow the protocols designed for patients in intensive care units (ICUs). Objective: To assess the effects of using 0.12% chlorhexidine solution in reducing the number of microorganisms in the saliva of ICU patients. Methodology: Cohort study with 45 volunteers divided into Medical Clinic (control group, oral self-care), non-intubated ICU, and intubated ICU. Oral hygiene in the ICU was performed with chlorhexidine. Microbiological analysis was performed through salivary bacterial count. Data were analyzed using ANOVA. Results: The number of microorganisms decreased after oral hygiene. A significant difference was found between the control and the ICU intubated groups in the immediate period and after 30 minutes. The number of microorganisms in intubated patients decreased 12 hours after oral hygiene with chlorhexidine. Conclusion: The number of oral microorganisms decreases in intubated patients 12 hours after oral hygiene with chlorhexidine. These results may contribute to elaborating oral hygiene protocols for ICUs and planning strategies, for example, to reduce the costs and the side effects associated with chlorhexidine use.
Resumen Marco contextual: El control de la biopelícula oral con antisépticos debe ser adecuado a los protocolos elaborados para los pacientes de una unidad de cuidados intensivos (UCI). Objetivo: Evaluar el efecto de la solución de clorhexidina al 0,12% en la reducción de los microorganismos en la saliva de los pacientes en una UCI. Metodología: Estudio de cohorte con 45 voluntarios divididos en Clínica Médica (control, autohigiene bucal), UCI no intubados y UCI intubados. La higiene bucal en la UCI se realizó con clorhexidina. El análisis microbiológico se realizó con el recuento de microorganismos en la saliva. El análisis de los datos se realizó con ANOVA. Resultados: Hubo una reducción de los microorganismos después de la higiene bucal. El control mostró una diferencia significativa con los pacientes intubados en la UCI en el momento y después de 30 minutos. Los pacientes intubados mostraron una reducción de los microorganismos hasta 12 horas después de la higiene con clorhexidina. Conclusión: La higiene con clorhexidina reduce en un máximo de 12 horas los microorganismos bucales en pacientes intubados. Estos resultados pueden contribuir a la elaboración de protocolos de higiene bucal en las UCI, además de apoyar estrategias como la reducción de costes y los efectos secundarios asociados a la clorhexidina.
ABSTRACT
AIMS: It has been shown that periodontitis, can be modified by systemic changes, including behavioral factors, such as diet. Caloric restriction is one of the dietary therapeutic strategies indicated for obesity. It is associated with several benefits, among them, modulation of the inflammatory response. The aim of this study was to verify whether caloric restriction in obese rats changes the progression of experimental ligature-induced periodontitis. MATERIALS AND METHODS: Forty-eight Wistar rats were used for 24 weeks and initially fed with cafeteria diet during 12 weeks. The animals were divided into four groups according to the caloric restriction and experimental periodontitis. The cotton thread was placed around the mandibular first molars, for 15 days, before the end of the experiment. Rats submitted to caloric restriction received, from the 13th week of the experimental protocol, 70% of the food intake compared to the ad libitum animals of other study of the our research group. Alveolar bone loss was assessed using macroscopic morphometric analysis. Analyzes of clinical periodontal measures, biometrics, serum biomarkers and biochemical parameters were performed. KEY FINDINGS: Caloric restriction decreased the alveolar bone loss in the periodontitis group when compared to the group that received a cafeteria diet with periodontitis. Moreover, the results demonstrate the improvement in the glycemic profile, without prejudice to bone tissue biomarkers. SIGNIFICANCE: Based on the results, caloric restriction reduces the progression of alveolar bone loss in rats with experimental periodontitis, in addition to presenting benefits in biometric data, decreasing both glycemic profile and clinical periodontal measures.
