RESUMO

La enfermedad COVID-19 fue declarada pandemia por la Organización Mundial de la Salud el 11 de marzo de 2020. El síndrome respiratorio agudo severo coronavirus-2 (SARS-CoV-2) es un virus transmitido de animales a seres humanos, altamente contagioso, cuyo periodo de incubación es de uno a 14 días. Los momentos por los que atraviesan la mayoría de los países debido a la pandemia declarada del COVID-19 han llevado a la proclamación de órdenes gubernamentales y/o recomendaciones en relación a la atención dental que debe dispensarse. En el momento actual, no se dispone de protocolos específicos oficiales, ni nacionales ni internacionales, que aborden de manera clara cómo debe proceder el odontólogo en su práctica diaria en la etapa posterior al confinamiento para trabajar con las mejores garantías de protección para los pacientes y el equipo humano de la consulta odontológica. Este estudio tuvo como objetivo analizar consideraciones para la atención de tratamientos endodóncicos en el contexto de la pandemia de COVID-19. Para lograr este objetivo se realizó una revisión bibliográfica en diferentes bases de datos, como: Google Scholar, Springer Link, Scopus, PubMed, para ello se emplearon estrategias de búsqueda, utilizando descriptores como: «endodontic¼, «recomendations¼, «odontology¼, «COVID-19¼, «pandemic¼ y operadores booleanos, con la finalidad de obtener información relevante y precisa. Contribuyendo a la práctica de la endodoncia con un protocolo general para el manejo de emergencias que muestre el fundamento del diagnóstico, los procedimientos clínicos y el uso de equipos de protección personal y barreras en el consultorio odontológico durante el brote de COVID-19 (AU)


The COVID-19 disease was declared a pandemic by the World Health Organization on March 11, 2020. The severe acute respiratory syndrome coronavirus (SARS-CoV-2) is a virus transmitted from animals to humans, highly contagious, whose incubation period is one to 14 days. The times that most countries are going through due to the declared COVID-19 pandemic have led to the proclamation of government orders and/or recommendations regarding the dental care that should be provided. At the present time, there are no specific official national or international protocols that clearly address how the dentist should proceed, in their daily practice, in the post-confinement stage, to work with the best guarantees of protection for the patients and the human team of the dental practice. The objective of this study was to analyze considerations for the care of endodontic treatments in the context of the COVID-19 pandemic. To achieve this objective, a bibliographic review was carried out in different databases, such as: Google Scholar, Springer Link, Scopus, PubMed, for this, search strategies were used, using descriptors such as: «endodontic¼, «recommendations¼, «odontology¼, «COVID-19¼, «pandemic¼ and Boolean operators, in order to obtain relevant and accurate information. Contributing to the practice of endodontics a general protocol for emergency management that shows the rationale for diagnosis, clinical procedures and the use of personal protective equipment and barriers in the dental office during the COVID-19 outbreak (AU)

RESUMO

Existe una creciente preocupación sobre el tema de la infección cruzada en clínicas y laboratorios dentales. El laboratorio odontológico debe seguir normas de bioseguridad que garanticen a todo el equipo de salud la prevención de estas infecciones. Los técnicos que allí laboran corren el riesgo de exponer su cara a salpicaduras, así como a rocíos de sangre y saliva. Este estudio fue diseñado para saber si los laboratorios a los que recurrimos cumplen con estas normas de bioseguridad, y qué tan confiados podemos estar de la desinfección por parte de ellos, ya que las prótesis deberían estar desinfectadas correctamente antes de colocarlas en boca (AU)


There is growing concern about the issue of cross infection in dental clinics and laboratories. The dental laboratory must follow biosafety standards that guarantee the prevention of these infections to the entire health team. The technicians who work there run the risk of exposing their face to splashes and spray of blood and saliva. This study was designed to find out if the laboratories we use comply with these biosafety standards, and how confident we can be of their disinfection by them, since the prostheses should be properly disinfected before placing them in the mouth (AU)

RESUMO

AIM: To assess the distribution and deposition of aerosols during simulated periodontal therapy. METHODS: A manikin with simulated fluorescein salivation was treated by four experienced dentists applying two different periodontal treatment options, i.e. air-polishing with an airflow device or ultrasonic scaling in the upper and lower anterior front for 5 minutes, respectively. Aerosol deposition was quantitatively measured on 21 pre-defined locations with varying distances to the manikins mouth in triplicates using absorbent filter papers. RESULTS: The selected periodontal interventions resulted in different contamination levels around the patient's mouth. The highest contamination could be measured on probes on the patient's chest and forehead but also on the practitioner's glove. With increasing distance to the working site contamination of the probes decreased with both devices. Air-polishing led to greater contamination than ultrasonic. CONCLUSION: Both devices showed contamination of the nearby structures, less contamination was detected when using the ultrasonic. Affirming the value of wearing protective equipment we support the need for universal barrier precautions and effective routine infection control in dental practice.

RESUMO

A finales de 2019 se identificó el virus SARS-CoV-2 (por su significado en inglés Severe Acute Respiratory Syndrome Coronavirus 2) como agente etiológico de la COVID-19 (por su significado en inglés coronavirus disease 2019) en la ciudad de Wuhan, China. Debido a su rápida propagación al resto del mundo durante el primer trimestre del año 2020, la Organización Mundial de la Salud (OMS) la declaró pandemia mundial en marzo del mismo año. Por el potencial de contagio de COVID-19 se ha considerado que el entorno clínico en el que se desenvuelve la odontología puede ser de alto riesgo para el paciente, el odontólogo y sus asistentes si no se tienen las medidas de bioseguridad adecuadas. En un principio se vieron suspendidas las consultas regulares; sin embargo, al volver a la actividad laboral se han adaptado protocolos para el control de infecciones como reforzar el uso de barreras de protección y minimizar tratamientos que involucren aerosoles. La caries es uno de los principales motivos de consulta en la odontología pediátrica, por lo que en este escrito se sugieren algunos protocolos basados en la mínima invasión que prescinden de instrumental rotatorio para salvaguardar al paciente en riesgo de contagio, reduciendo el número de visitas y tiempo en consulta e incluso controlando algunos aspectos de salud bucal fuera de consulta clínica por medio de estrategias preventivas que pueden llevarse a cabo desde casa. Esto significa también mantener la tranquilidad por parte de los tutores del paciente ante la pandemia que se vive actualmente (AU)


At the end of 2019, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was identified as the etiological agent of COVID-19 in the city of Wuhan China. Due to its rapid spread to the rest of the world during the first trimester of 2020, the WHO declared a global pandemic in March of the same year. Due to the contagion potential of COVID-19, it has been considered that the clinical environment in which dentistry operates may be in high risk for the patient if the appropriate biosafety measures are not taken, initially clinical practices were suspended. However, when returning to work, protocols have been adapted to the infection control procedures, reinforced the use of protective barriers, and minimize treatments that involve aerosols. Caries is one of the main reasons for consultation in Pediatric Dentistry, this article suggests some protocols based on minimal invasion that dispense with rotating instruments to safeguard the patient from the risk of contagion, reducing the number of visits and time in consultation and even controlling some aspects of the oral health outside the dental visit through preventive strategies that can be carried out from home. Modifications to Dental Home. This should include maintaining tranquility and calm on the part of the patient's tutors in the face of the pandemic that we are currently experiencing (AU)

RESUMO

BACKGROUND: Many dental procedures produce aerosols (droplets, droplet nuclei and splatter) that harbour various pathogenic micro-organisms and may pose a risk for the spread of infections between dentist and patient. The COVID-19 pandemic has led to greater concern about this risk. OBJECTIVES: To assess the effectiveness of methods used during dental treatment procedures to minimize aerosol production and reduce or neutralize contamination in aerosols. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases on 17 September 2020: Cochrane Oral Health's Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (in the Cochrane Library, 2020, Issue 8), MEDLINE Ovid (from 1946); Embase Ovid (from 1980); the WHO COVID-19 Global literature on coronavirus disease; the US National Institutes of Health Trials Registry (ClinicalTrials.gov); and the Cochrane COVID-19 Study Register. We placed no restrictions on the language or date of publication. SELECTION CRITERIA: We included randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on aerosol-generating procedures (AGPs) performed by dental healthcare providers that evaluated methods to reduce contaminated aerosols in dental clinics (excluding preprocedural mouthrinses). The primary outcomes were incidence of infection in dental staff or patients, and reduction in volume and level of contaminated aerosols in the operative environment. The secondary outcomes were cost, accessibility and feasibility. DATA COLLECTION AND ANALYSIS: Two review authors screened search results, extracted data from the included studies, assessed the risk of bias in the studies, and judged the certainty of the available evidence. We used mean differences (MDs) and 95% confidence intervals (CIs) as the effect estimate for continuous outcomes, and random-effects meta-analysis to combine data. We assessed heterogeneity. MAIN RESULTS: We included 16 studies with 425 participants aged 5 to 69 years. Eight studies had high risk of bias; eight had unclear risk of bias. No studies measured infection. All studies measured bacterial contamination using the surrogate outcome of colony-forming units (CFU). Two studies measured contamination per volume of air sampled at different distances from the patient's mouth, and 14 studies sampled particles on agar plates at specific distances from the patient's mouth. The results presented below should be interpreted with caution as the evidence is very low certainty due to heterogeneity, risk of bias, small sample sizes and wide confidence intervals. Moreover, we do not know the 'minimal clinically important difference' in CFU. High-volume evacuator Use of a high-volume evacuator (HVE) may reduce bacterial contamination in aerosols less than one foot (~ 30 cm) from a patient's mouth (MD -47.41, 95% CI -92.76 to -2.06; 3 RCTs, 122 participants (two studies had split-mouth design); very high heterogeneity I² = 95%), but not at longer distances (MD -1.00, -2.56 to 0.56; 1 RCT, 80 participants). One split-mouth RCT (six participants) found that HVE may not be more effective than conventional dental suction (saliva ejector or low-volume evacuator) at 40 cm (MD CFU -2.30, 95% CI -5.32 to 0.72) or 150 cm (MD -2.20, 95% CI -14.01 to 9.61). Dental isolation combination system One RCT (50 participants) found that there may be no difference in CFU between a combination system (Isolite) and a saliva ejector (low-volume evacuator) during AGPs (MD -0.31, 95% CI -0.82 to 0.20) or after AGPs (MD -0.35, -0.99 to 0.29). However, an 'n of 1' design study showed that the combination system may reduce CFU compared with rubber dam plus HVE (MD -125.20, 95% CI -174.02 to -76.38) or HVE (MD -109.30, 95% CI -153.01 to -65.59). Rubber dam One split-mouth RCT (10 participants) receiving dental treatment, found that there may be a reduction in CFU with rubber dam at one-metre (MD -16.20, 95% CI -19.36 to -13.04) and two-metre distance (MD -11.70, 95% CI -15.82 to -7.58). One RCT of 47 dental students found use of rubber dam may make no difference in CFU at the forehead (MD 0.98, 95% CI -0.73 to 2.70) and occipital region of the operator (MD 0.77, 95% CI -0.46 to 2.00). One split-mouth RCT (21 participants) found that rubber dam plus HVE may reduce CFU more than cotton roll plus HVE on the patient's chest (MD -251.00, 95% CI -267.95 to -234.05) and dental unit light (MD -12.70, 95% CI -12.85 to -12.55). Air cleaning systems One split-mouth CCT (two participants) used a local stand-alone air cleaning system (ACS), which may reduce aerosol contamination during cavity preparation (MD -66.70 CFU, 95% CI -120.15 to -13.25 per cubic metre) or ultrasonic scaling (MD -32.40, 95% CI - 51.55 to -13.25). Another CCT (50 participants) found that laminar flow in the dental clinic combined with a HEPA filter may reduce contamination approximately 76 cm from the floor (MD -483.56 CFU, 95% CI -550.02 to -417.10 per cubic feet per minute per patient) and 20 cm to 30 cm from the patient's mouth (MD -319.14 CFU, 95% CI - 385.60 to -252.68). Disinfectants ‒ antimicrobial coolants Two RCTs evaluated use of antimicrobial coolants during ultrasonic scaling. Compared with distilled water, coolant containing chlorhexidine (CHX), cinnamon extract coolant or povidone iodine may reduce CFU: CHX (MD -124.00, 95% CI -135.78 to -112.22; 20 participants), povidone iodine (MD -656.45, 95% CI -672.74 to -640.16; 40 participants), cinnamon (MD -644.55, 95% CI -668.70 to -620.40; 40 participants). CHX coolant may reduce CFU more than povidone iodine (MD -59.30, 95% CI -64.16 to -54.44; 20 participants), but not more than cinnamon extract (MD -11.90, 95% CI -35.88 to 12.08; 40 participants). AUTHORS' CONCLUSIONS: We found no studies that evaluated disease transmission via aerosols in a dental setting; and no evidence about viral contamination in aerosols. All of the included studies measured bacterial contamination using colony-forming units. There appeared to be some benefit from the interventions evaluated but the available evidence is very low certainty so we are unable to draw reliable conclusions. We did not find any studies on methods such as ventilation, ionization, ozonisation, UV light and fogging. Studies are needed that measure contamination in aerosols, size distribution of aerosols and infection transmission risk for respiratory diseases such as COVID-19 in dental patients and staff.

RESUMO

La pandemia de enfermedad por coronavirus de 2019 (Covid-19) se ha convertido en un importante desafío de salud pública para todos los países. Las medidas de control de infecciones son necesarias para disminuir la circulación del virus y evitar que se siga propagando mundialmente. Debido a las características de los entornos odontológicos, el riesgo de infección cruzada entre los pacientes y los odontólogos es alto. Es por esto que se requieren protocolos de control de infecciones estrictos y efectivos. Elaborar estrategias de gestión del riesgo en salud en odontología permitirá brindar un entorno de seguridad para el paciente, el profesional y su equipo (AU)


The Covid-19 pandemic has become a major public health challenge all over the world. Infection control measures are necessary to prevent the virus from spreading further and to help to control the situation worldwide. Due to the characteristics of the dental environment, the risk of cross infection is high between patients and dentists. It is important to develop strict infection control protocols to provide a safety environment for the patient and the dental staff (AU)

RESUMO

Catalogada su labor como Servicios de Salud Indispensables, el profesional de la odontología se ha mantenido al pendiente de sus pacientes durante la pandemia de COVID-19, brindando atención de urgencia a quien lo solicita. A su regreso a la práctica típica, el odontólogo encontrará un entorno distinto o NUEVA NORMALIDAD, viéndose obligado a hacer modificaciones clínicas pertinentes y preparar a su equipo de trabajo para continuar brindando atención de calidad con un margen de seguridad amplificado, que de igual manera proteja a pacientes y al equipo de trabajo. Ante la falta de una vacuna que brinde protección y de tratamiento específico contra el SARS-CoV-2 (COVID-19), elevar el nivel de control de infecciones en el consultorio se vuelve ineludible y posiblemente irreversible en el quehacer odontológico cotidiano. En este artículo se propone un Protocolo de Control de Infecciones en la consulta odontológica que permita brindar seguridad en la atención bucal, considerando COVID-19, útil también para control infeccioso de otros patógenos virales o bacterianos (AU)


Considered dentistry as an Indispensable Health Services, during the COVID-19 pandemic the dental professional has been providing mostly emergency care. Upon return to typical dental practice, the dentist will find a different environment or NEW NORMALLY, being forced to make relevant clinical modifications and prepare his team to continue providing quality care with an amplified safety margin, which equally protects patients and dental team. In the absence of an available vaccine that provides protection or a specific treatment against SARSCoV- 2 (COVID-19), raising the level of infection control at the dental office will become unavoidable and possibly irreversible in the future quotidian dental work. This article proposes an Infection Control Protocol for the dental consultation that allows provide safety oral care, considering COVID-19, also useful for other viral or bacterial pathogens control (AU)

RESUMO

El surgimiento de infecciones originadas por el SARS-CoV-2 en el humano ha desencadenado una serie de conflictos de salud, económicos y sociales en el entorno mundial. El área odontológica debe poseer todo el conocimiento necesario acerca de esta pandemia debido a que, como profesionales de la salud y responsables de la condición bucal de la sociedad, es de vital importancia disminuir el riesgo que presentan las enfermedades crónicas no transmisibles, cáncer, obesidad y otras, así como de los adultos mayores para que no generen un problema de salud severo y que además puedan ser asociadas con la presencia del COVID-19. Es importante conocer cuáles son las pautas por considerar en la práctica odontológica para una atención odontológica oportuna y eficaz manteniendo la bioseguridad del personal de salud. Por lo tanto, se genera esta guía de atención odontológica basada en la evidencia científica publicada para el conocimiento y dominio del profesional de salud oral (AU)


The emergence of human infections caused by SRAS-CoV-2 has triggered a series of health, economic and social conflicts in the global environment. The dental area must have all the necessary knowledge about this pandemic because, as a health professional and responsible for the oral condition of society, it is vitally important to reduce the risk of chronic non-communicable diseases, cancer, obesity and others, as well as older adults so that they do not generate a health problem and that may also be associated with the presence of COVID-19. It is important to know the problems of the guidelines to consider in dental practice for effective dental care and biosafety of health personnel. Therefore, this dental care guide is generated based on published scientific evidence for the knowledge and domain of the oral health professional (AU)

RESUMO

A photocrosslinkable gelatin methacryloyl (GelMA) hydrogel has been widely examined in regenerative engineering because of its good cell-tissue affinity and degradability in the presence of matrix metalloproteinases. A halloysite aluminosilicate nanotube (HNT) is a known reservoir for the loading and sustained delivery of therapeutics. Here, we formulate injectable chlorhexidine (CHX)-loaded nanotube-modified GelMA hydrogel that is cytocompatible and biodegradable and provides sustained release of CHX for infection ablation while displaying good biocompatibility. The effects of HNTs and CHX on hydrogel degradability and mechanical properties, as well as on the kinetics of CHX release, and on the antimicrobial efficacy against oral pathogens were systematically assessed. Cytocompatibility in stem cells from human exfoliated deciduous teeth and inflammatory response in vivo using a subcutaneous rat model were determined. Our hydrogel system, that is, (CHX)-loaded nanotube-modified GelMA showed minimum localized inflammatory responses, supporting its ability for drug delivery applications. Moreover, we showed that the incorporation of CHX-loaded nanotubes reduces the mechanical properties, increases the swelling ratio, and diminishes the degradation rate of the hydrogels. Importantly, the presence of CHX-loaded nanotubes inhibits bacterial growth with minimal cell toxicity. Our findings provide a new strategy to modify GelMA hydrogel with chlorhexidine-loaded nanotubes for clinical use as an injectable drug delivery strategy for dental infection ablation.

RESUMO

Aims: The aim of this study was to determine the best approach to reduce the unfavorable change in the three different dimensions of impressions using disinfection durations of 15 and 30 min; three different disinfection procedures; and alginate impression products as research factors. Materials and Methods: CA37, impressional, and cream alginate impressions were used; distortion in the AB, AC, and BC dimensions of impressions using disinfection durations of 15 and 30 min was studied; and no disinfection (ND), conventional disinfection (CD), and sonicator-activated disinfection (SAD) procedures were measured. Results: Regarding AB dimension, the impressional has best performance when CD was applied for both 15 and 30 min. When SAD was applied for 15 min, impressional and cream alginates provide best performance. When CD was applied for 15 min, CA37 and impressional alginates provide best performance. Although ND-applied CA37 alginate after 30 min provides best performance, because of many outlier values, its implication may not be considered as meaningful. Regarding AC dimension, cream alginate has best performance when CD was applied for 15 min. The AC distances in all the alginates are considerably different from the base model after 30 min. Regarding BC dimension, only the CA37 alginate has the best performance when ND was applied for 15 min. All the alginates are considerably different from that of the base model after 30 min. Conclusion: Preference of 15-min disinfection can provide favorable results to obtain all impressions with minimally distorted dimensions. CD is an adequate procedure. The studied SAD needs to be developed further. All alginates are comparably successful to obtain impressions with desired distortion degrees.

RESUMO

Water is essential during dental care. Physical and chemical techniques should be used to maintain a good water quality with respect to bacteria, and to ensure the safety of exposed patients and dental staff. The aim of this survey was to assess the modalities used by dental practitioners in Eastern France to maintain the water quality of their dental unit waterlines (DUWLs). A questionnaire about water quality maintenance practices was sent to 870 dental offices in 2016. The questionnaires were completed by 153 dental offices, covering about 223 dental care units. The majority of units were fed by mains water (91.0%), which is generally unfiltered (71.3%). One-third (33.6%) of the units had an independent water bottle reservoir. Flushing, a basic physical technique to improve the quality of units' outflow water, was practiced in 65.4% of dental offices. Concerning the chemical treatment of water, it was used for 62.1% of the units. An analysis of the microbiological quality of the DUWL water was only carried out in 2.6% of the offices. In conclusion, providing better training to dental staff seems necessary to improve their practices and to generalize procedures that improve the microbiological quality of the water used.

RESUMO

Los profesionales de la salud están expuestos a una gran variedad de microorganismos desde esporas, bacterias, hongos, virus y protozoarios que pueden encontrarse en la sangre y/o saliva de los pacientes. Cualquiera de estos microorganismos puede causar una enfermedad infectocontagiosa a través de pinchazos y/o salpicaduras producidas por el aerosol durante la práctica dental. Objetivo: Determinar la presencia bacteriana en las piezas de alta velocidad utilizadas en la práctica clínica. Material y métodos: Es un estudio experimental, observacional y transversal en el que se evaluó la contaminación de 30 piezas de alta velocidad utilizadas en la práctica clínica. Previo al estudio se efectuó una estandarización obteniendo una kappa del 0.85. Se realizó una base de datos en el programa SPSS versión 22, con el que se llevó a cabo el análisis descriptivo para determinar medidas de tendencia central. Resultados: 73.3% de las muestras analizadas tuvieron crecimiento bacteriano, entre las bacterias que se encontraron resultó que 54.5% de ellas fueron bacterias Gram positivas y el resto Gram negativas. La bacteria con mayor presencia en la muestra fue el Bacillus en 45.5% seguida del Streptococcus en 27.3%, el restante 27.2% fue Staphylococcus, Coccus y Streptobacillus. Conclusiones: El uso correcto de las piezas de alta, así como su desinfección en la consulta dental es de suma importancia, ya que nos ayudan a evitar contaminaciones cruzadas y a prevenir que dentro del área de trabajo se formen focos de infección (AU)


Health professionals are exposed to a wide variety of microorganisms from spores, bacteria, fungi, viruses and protozoa that can be found in the blood and/or saliva of patients. Any of these microorganisms can cause an infectious disease through punctures and / or splashes produced by the aerosol during dental practice.1,2 Objective: To determine the bacterial presence in the high-speed pieces used in clinical practice. Material and methods: It are an experimental, observational and transversal study; where the contamination of 30 high-speed pieces used in clinical practice was evaluated. Prior to the study, a standardization was made obtaining a kappa of 0.85. A database was made in the program SPSS version 22, with which the descriptive analysis was carried out to determine measures of central tendency. Results: 73.3% of the analyzed samples showed bacterial growth, among the bacteria that were found, 54.5% of them were gram-positive bacteria and the rest were gram-negative. The bacterium with the highest presence in the sample was for Bacillus in 45.5% followed by Streptococcus in 27.3%, the remaining 27.2% was for Staphylococcus, Coccus and Streptobacillus. Conclusions: The correct use of the discharging parts, as well as their disinfection in the dental practice is of the utmost importance as they help us to avoid cross contamination and to prevent foci of infection from forming within the work area (AU)

RESUMO

OBJETIVOS: La mayoría de las infecciones cervicales profundas son polimicrobianas y de origen dental, y es necesario un tratamiento apropiado y oportuno. El propósito de esta investigación es describir la eficacia de las incisiones mínimamente invasivas para el drenaje de infecciones cervicales profundas. MATERIALES Y MÉTODOS: Estudio descriptivo, retrospectivo y longitudinal en pacientes con infecciones cervicales profundas, que requirieron ingreso hospitalario, tratados quirúrgicamente con múltiples incisiones mínimamente invasivas. Los datos recopilados incluyeron epidemiología, etiología, órganos dentales y espacio cervicofacial involucrado, tamaño de los abscesos, cantidad de material obtenido, tiempo de hospitalización, tiempo de evolución antes del drenaje, técnica anestésica, método de intubación, método quirúrgico y complicaciones. RESULTADOS: Fueron incluidos un total de 88 pacientes, con un promedio de edad de 39 +/- 14,05 años y una mayor prevalencia del género femenino. El factor etiológico principal fueron los focos sépticos dentales. El espacio más afectado fue el submandibular, en un 39,2 %. El tiempo de evolución antes del drenaje varió entre 1 y 8 días. El promedio del tamaño de los abscesos fue de 6,47 +/- 2,34, 4,03 +/- 1,64, 3,71 +/- 1,59 cm. Un 88,6 % de los pacientes fueron intervenidos bajo anestesia local y un 11,8 % bajo anestesia general. El promedio de la cantidad de material obtenido fue de 104,41 +/- 9 cc. El tiempo promedio de hospitalización fue de 9,43 +/- 3,89 días. No hubo complicaciones locales ni sistémicas. CONCLUSIONES: Las incisiones mínimamente invasivas constituyen una alternativa eficaz, segura y con escasas morbilidades para el drenaje de infecciones cervicales profundas


AIM: Most of deep cervical infections are polymicrobial and come from a dental origin, and an appropriate treatment is necessary. The present paper aims to describe the efficiency of minimally invasive incisions for the drainage of deep cervical infections. MATERIALS AND METHODS: A descriptive, retrospective and longitudinal study in patients with deep cervical infections, who required hospital admission. Patients were surgically treated with multiple minimally invasive incisions. Collected data included: epidemiology, etiology, teeth and cevicofacial spaces involved, size of drained abscesses, amount of material obtained, time of total patient admission, time of evolution before drainage anaesthetic technique, intubation method, surgical method and complications. RESULTS: A total of 88 patients were included in this study, with an average age of 39 +/- 14.05 years and a higher prevalence in women. Teeth infections were the etiological factor in 100 % of the sample. The most affected space was the submandibular with a 39.2 %. The evolution time before drainage varied between 1-8 days. The mean abscess size was 6.47 +/- 2.34, 4.03 +/- 1.64, 3.71 +/- 1.59 cm. In terms of anaesthetic techniques, 88.6% patients were treated under local anesthesia and 11.3 % patients were treated under general anesthesia. The average of the amount of material obtained was 104.41 +/- 9 cc. The average hospitalization time was 9.43 +/- 3.89 days. There were no systemic or local complications. CONCLUSIONS: Minimally invasive incisions represent an effective and safe alternative, with low morbidity, for the drainage of deep cervical infections

RESUMO

ABSTRACT: The contamination of the dental units' waterlines is a reality, which can develop individual and collective disorders. The aim of this study was to evaluate the prevalence and resistance profile of bacteria on the internal surfaces of waterlines in a dental clinic from a Dentistry school of a Brazilian university. The design was an exploratory, descriptive study with quantitative and qualitative approach. Samples (n=4) were collected for analysis at different points: the portion closest to the water reservoir of the chair, and the portion closest to the triple syringe. After collection the samples were cultured in BHI medium in an oven for 24-48 h at 37 °C. For the quantitative analysis 1 ml of each sample was used for serial dilution up to the dilution value seven. The colonies were counted after pour plate and the results expressed in UFC/cm2. The qualitative analysis was initiated with the cultivation of Agar Blood, EMB-Levine and Cetrimide Agar for 24 h, and the identification of bacteria was performed by microscopic analyses. The resistance profile was verified by classical antibiogram. The internal surfaces of unit waterlines units exhibited a mean of 2.44 x 109 CFU / cm2. Bacillus subtilis and Pseudomonas aeruginosa were identified. The resistance profile of Pseudomonas aeruginosa indicated sensitivity to all tested antibiotics. A large number of microorganisms was quantified from biofilm accumulated in the dental units' waterlines. However, they were not resistant to classic antibiogram. Better management and application of decontamination protocols for waterlines need to be applied since opportunistic infections may be associated with Pseudomonas aeruginosa.


RESUMEN: La contaminación de líneas de agua en las unidades dentarias es una realidad, generando enfermedades individuales y colectivas. El objetivo de este estudio fue evaluar la prevalencia y resistencia de las bacterias en las zonas internas de las líneas de agua de la Facultad de Odontología de una universidad brasileña. El diseño del estudio fue exploratorio, descriptivo con enfoques cuantitativos y cualitativos. Las muestras para análisis (n=4) fueron selecionadas de distintos lugares: el punto más cercano al sistema de agua del sillón odontológico y el punto más cercano a la jeringa tríplice. Las muestras obtenidas fueron cultivadas en un médio BHI por 24-48 h, en un horno a 37 ºC. Para el análisis cuantitativo, se utilizó 1 ml de cada muestra para dilución hasta el valor siete. Las colonias fueran contadas y los resultados fueron expresados en UFC/cm2. El análisis cualitativo fue iniciado con el cultivo de Agar Sangre, EBM-Levine y Agar Cetrimide por 24 h y la identificación de la bacteria fue realizada por análisis microscópicos. El perfil de resistencia fue verificado por el antibiograma clásico. Las zonas internas de las unidades de líneas de agua mostraron un promédio de 2,44 x 109 UFC/cm2. Bacillus subtilis y Pseudomonas aeruginosa fueron encontrados. El perfil de resistencia de Pseudomonas aeruginosa indicó sensibilidad a todos los antibióticos testados. Un gran número de microorganismos fue cuantificado desde la biopelícula acumulada en las líneas de agua de unidades dentales. Sin embargo, no resistieron al antibiograma clásico. Se requiere una mejor gestión y aplicación de protocolos de decontaminación en las líneas de agua debido a que las infecciones oportunistas puedan estar asociadas a Pseudomonas aeruginosa.
