RESUMEN
Background: Patients admitted to the Intensive Care Unit (ICU) are at greater risk of developing nosocomial infections due to their investigations, treatment and changes in the immune system. One of the most prevalent nosocomial infections is respiratory tract infection, such as hospital acquired pneumonia and ventilator-associated pneumonia (VAP). The bacteria commonly found in the oral cavity in the hospital environment are Streptococcus viridians, Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus spp., and Klebsiella pneumoniae. There is a need to test and define appropriate standard protocols for oral hygiene in patients undergoing mechanical ventilation in ICUs through the intervention of a dental specialist, preventing the proliferation of microorganisms into the respiratory tract, thus reducing hospitalization time, the use of antibiotics, and increased morbidity/mortality. Objective: This study aimed to evaluate the effectiveness of dental brushing in the reduction of the pathogenic buccal microbiota associated with mechanical ventilation in patients admitted to the Evangelical Hospital from Londrina, Paraná, Brazil. Methodology: The sample consisted of 90 patients (of both sexes), mean age of 65 years, under mechanical ventilation by orotracheal tube and tracheostomized patients, without suspected or confirmed diagnosis of pneumonia. Patients were randomized ∗∗∗. Results: Results showed that oral hygiene using a toothbrush by suction, with chlorhexidine gel 0.12% (Group B), was more effective than conventional hygiene using gauze soaked with chlorhexidine 0.12% (Group A) in reducing pathogenic buccal microbiota. Conclusions: There was a reduction of the pathogenic buccal microbiota in mechanically ventilated patients receiving oral hygiene using a toothbrush by suction with chlorhexidine gel 0.12% (Group B).
RESUMEN
RESUMEN Introducción: La estomatitis subprotésica es un proceso inflamatorio de la mucosa bucal que se encuentra cubierta por una prótesis removible, de causa multifactorial y alta prevalencia. Objetivo: Caracterizar la estomatitis subprotésica en pacientes portadores de prótesis removible atendidos en las clínicas odontológicas de la Universidad San Gregorio de Portoviejo en el período marzo-noviembre de 2019. Método: Se realizó un estudio descriptivo transversal, con los criterios de inclusión siguientes: mayores de 18 años, ambos sexos, buen estado de salud general, no practicar hábitos tóxicos, usar prótesis removible, total o parcial, confeccionada de acrílico o metales. Todos los sujetos de la investigación firmaron el consentimiento informado antes de realizarles la historia clínica de odontología del Ministerio de Salud Pública del Ecuador de donde se extrajeron los datos sociodemográficos, signos clínicos y características de la prótesis. Resultados: Fueron evaluados 100 pacientes. El 45 %, presentaba signos clínicos de estomatitis subprotésica; predominó el sexo femenino con el 33 % y el grupo de edad de 40 a 59 años con un 26 %. La mayoría de las prótesis no se ajustan ni adaptan de manera correcta, y tienen un mal estado físico, en el 80, 82,2 y el 91 %, respectivamente. El 84,4 % de los pacientes utilizaba prótesis parcial removible, confeccionadas con acrílico, por un periodo de 1 a 6 años en el 60 % de los casos. Conclusiones: El diagnóstico de estomatitis subprotésica se asocia con el mal estado físico, desajuste e inadecuada adaptación de las prótesis removibles, lo que indica la necesidad de la institución para el establecimiento de estrategias docentes hacia la comunidad para su prevención y diagnóstico temprano.
ABSTRACT Introduction: Subprosthetic stomatitis is an inflammatory process of the mucosa in the oral cavity covered by a removable prosthesis, with a multifactorial cause and high prevalence. Objective: To characterize subprosthetic stomatitis in patients with removable prosthesis treated at the dental clinics of San Gregorio University in Portoviejo in the period March-November 2019. Method: A cross-sectional descriptive study was conducted, with the following inclusion criteria: patients over 18 years old, both sexes, good general health, no toxic habits, use of removable prosthesis, total or partial, made of acrylic or metals. All the patients involved in the research signed their consent, information given to them before taking their dental records taken by the Ministry of Public Health of Ecuador, from which socio-demographic data, clinical signs and characteristics of the prosthesis were extracted. Results: 100 patients were evaluated. Forty-five per cent showed clinical signs of subprosthetic stomatitis; the female sex (33%) predominated and the age group 40-59 years with (26%). Most of the prosthesis did not fit or adapt correctly and were in poor physical condition in 80%, 82.2% and 91% respectively. 84.4% of the patients used removable partial prosthesis, made of acrylic, for a period of 1 to 6 years, (60%) of the cases. Conclusions: The diagnosis of subprosthetic stomatitis is associated with poor physical condition, maladjustment and inadequate adaptation of removable prostheses, which indicates the need for the institution to establish educational strategies towards the community for prevention and early diagnosis.
