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

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.

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

The present study aimed to test the antimicrobial activity of Streptococcus dentisani (S. dentisani) supernatant against a collection of microorganisms implicated in dental root infections, and to analyze morphological changes induced in a selection of the tested microorganisms. A total of 22 microbial species were selected, and their growth was monitored by spectrophotometry in the presence and absence of the supernatant of S. dentisani at different assay concentrations (0.2×, 1×, 2×). The generation time and maximum growth rates were evaluated under every tested condition. Scanning electron microscope (SEM) images were obtained to assess the effect on the cell surface following incubation of the pathogens with the concentrated (2×) supernatant of S. dentisani. The supernatant of S. dentisani was found to exert effective inhibitory activity against most of the studied microorganisms implicated in dental root infections (20 out of 22). Total growth inhibition was observed in the case of Streptococcus oralis, Streptococcus sobrinus, Streptococcus salivarius, Prevotella intermedia, and Streptococcus mutans, while the rest of the microorganisms showed an increase in the generation time (between 30 min and 4 h). SEM images revealed structural changes in the membrane consistent with bacteriocin activity, although the effects were heterogeneous among the different species tested.

RESUMO

Disinfection is a crucial aspect of patient care in dentistry. In the pre-19th century era, natural elements like acids, sulfur, mercury, and various alkaline metals were valued for their ability to obliterate pathogens. More recently aerosols, sprays, and disinfectant wipes with more powerful chemicals including quaternary ammonium compounds and aldehydes have become popular. As aerosols fall out of favor due to their health and environmental risks, disinfectant wipes are becoming the most trusted form of clinical sanitization. This article explores the history as well as the current practice of disinfection in the dental profession and further explores the variations in the use of surface disinfection based on the published literature. The current practice guidelines as recommended by agencies like Centers for Disease Control (CDC) were studied and summarized for this review.

RESUMO

BACKGROUND: Infection is one of the most crucial problems in health care services worldwide. It is considered one of the most important causes of morbidity and mortality associated with clinical, diagnostic and therapeutic procedures. Therefore, the purpose of this study was to investigate knowledge, attitude, and compliance with recommended infection control guidelines among dental faculty members and students at King Saud University, Riyadh, Kingdom of Saudi Arabia. METHODS: A cross-sectional study was conducted to obtain information regarding knowledge, attitude, and compliance with recommended infection control guidelines. The sample (n = 317) comprised of dental faculty members and students (3rd, 4th and 5th year) in both male and female campuses of College of Dentistry (KSU). This questionnaire contained three parts (knowledge, attitude, and compliance) and was distributed to the participants. After validation of the survey, data were collected, entered and analyzed by SPSS software. RESULTS: A total of 317 dental faculty members and students participated in this study. Out of the total study subjects, 141 (44.5%) were female and 176 (55.5%) were male. A comparison between dental faculty members and students was made based on their knowledge, attitude, and compliance, which resulted in almost equal percentages of knowledge (49.6, 49.0% respectively). In addition, it revealed that faculty members' attitude toward infection control in the dental clinic was more positive compared to their compliance with the infection control guidelines (70.6, 65.2% respectively) while with the students it was vice versa (67.2, 69.6% respectively). There is no statistically significant difference in the knowledge and attitude of dental faculty members and students regarding infection control guidelines (P > 0.05). CONCLUSION: Our study showed that dental undergraduate student and faculty members at KSU demonstrated a good adherence to infection control guidelines. On the other hand, there was a lack in the knowledge of the basics of infection control standards.

RESUMO

Background: Cleaning of re-usable medical devices is a critical control point in the decontamination cycle, although defined end-points of the process are controversial. Objective: Investigate cleaning efficacy and cost of different detergent classes in an automated washer disinfector (AWD) designed for dental practice. Methods: Loads comprised test soiled dental hand instruments in cassettes and extraction forceps. Residual protein assayed using the International standard method (ISO 15883-5:2005) 1% SDS elution with ortho-phthalaldehyde (OPA) or GBox technology (on instrument OPA analysis). Short (60 minutes) and long (97 minutes) AWD cycles were used with four different classes of detergents, tap water and reverse osmosis water. Results: SDS elution analysis (N = 612 instruments) demonstrated four detergents with both wash cycles achieved equivalent cleanliness levels and below a threshold of 200 µg protein/instrument. GBox methodology (N = 575) using UK Department of Health threshold of 5 µg/instrument side demonstrated that tap water performed with the greatest efficacy for all types of instruments and cycle types. Conclusions: Using International standard methodology, different detergent classes had equivalence in cleaning efficacy. Cheaper detergents used in this study performed with similar efficacy to more expensive solutions. Findings emphasise the importance of validating the detergent (type and concentration) for each AWD.

RESUMO

The increasing resistance to antibiotics and the aging of the population of patients who visit the dental practice can lead to more frequent infections with (resistant) microorganisms. The prevention of cross contamination by the implementation of effective measures in the area of hygiene and procedures of infection control is therefore important. The furnishing of a dental practice can play an important part in prevention. What are the important issues in furnishing a practice? A distinction is made between 'critical' and 'non-critical' rooms. Patients are only treated and instruments are only prepared for reuse in critical rooms. In these rooms, a strict separation is maintained between clean and contaminated, in both place and time. Only furniture that is strictly necessary for the treatment of patients is present in the critical rooms. Materials and equipment that are kept within the splatter area must be stored as much as possible in drawers and closed cabinets. Water taps can be controlled in a touch-free manner and are located within the present walking routes of the practice.

RESUMO

Background: Infection control practices are crucial and important elements in clinical dentistry as there is an increase in the prevalence of infectious diseases among dental patients. This necessitates the application of recommended procedures for infection control in dental schools and clinics. Objectives: The aim is to evaluate the awareness, knowledge, and attitude of the undergraduate dental students toward infection control measures in the prosthodontic clinic and to assess their satisfaction toward applying these measures during prosthodontic treatment. Materials and Methods: A questionnaire-based study was conducted among 180 third, fourth and fifth year dental students (119 females and 61 males) in November 2015 in a private dental school of Rani Durgawati University, Jabalpur (Madhya Pradesh), India. It included 25 close-ended questions related to vaccination status and previous sharp injuries, awareness, knowledge, and attitude toward infection control in the prosthodontic clinic, previous education about infection control, and subjects' satisfaction with their knowledge and attitude. The questionnaire was distributed among 3rd, 4th, and 5th year students and informed consent were obtained before commencing the questionnaire. Results: A total of 180 participants responded to the questionnaire. Their perception toward infection control practices in the prosthodontic clinic varied from 14.4% to 100%, where former were regularly disinfecting dental cast before sending it to the laboratory and later ones were regularly using gloves while attending the patient. Most of the subjects responded "good" or "fair" to the questions related to the evaluation of their knowledge and policy implementation of infection control in prosthodontic clinic (P < 0.0001). Around 47.8% were almost satisfied, and 28.9% were fairly satisfied with their knowledge and performance. Conclusions: The study findings showed inadequate attitude and awareness of subjects toward infection control in prosthodontic practice. Their self-assessment and satisfaction reflect their performance toward infection control policy.

RESUMO

Effective sterilization of reusable instruments contaminated by Creutzfeldt⁻Jakob disease in dental care is a crucial issue for public health. The present cross-sectional study investigated how the recommended procedures for sterilization were implemented by French dental practices in real-world settings. A sample of dental practices was selected in the French Rhône-Alpes region. Data were collected by a self-questionnaire in 2016. Sterilization procedures (n = 33) were classified into 4 groups: (1) Pre-sterilization cleaning of reusable instruments; (2) Biological verification of sterilization cycles—Monitoring steam sterilization procedures; (3) Autoclave performance and practitioner knowledge of autoclave use; (4) Monitoring and documentation of sterilization procedures—Tracking and tracing the instrumentation. Answers were provided per procedure, along with the global implementation of procedures within a group (over 80% correctly performed). Then it was verified how adherence to procedure groups varied with the size of the dental practice and the proportion of dental assistants within the team. Among the 179 questionnaires available for the analyses, adherence to the recommended procedures of sterilization noticeably varied between practices, from 20.7% to 82.6%. The median percentages of procedures correctly implemented per practice were 58.1%, 50.9%, 69.2% and 58.2%, in Groups 1, 2, 3 and 4, respectively (corresponding percentages for performing over 80% of the procedures in the group: 23.4%, 6.6%, 46.6% and 38.6%). Dental practices ≥ 3 dental units performed significantly better (>80%) procedures of Groups 2 and 4 (p = 0.01 and p = 0.002, respectively), while no other significant associations emerged. As a rule, practices complied poorly with the recommended procedures, despite partially improved results in bigger practices. Specific training regarding sterilization procedures and a better understanding of the reasons leading to their non-compliance are needed.

RESUMO

Objective: The aim of this study was to evaluate the antibacterial surface pretreatment methods against Streptococcus mutans within the infected dentin surface using a tooth cavity model. Material and Methods: Seventy-two cavities were prepared on caries-free third molars (n = 8). After sterilization, teeth were inoculated with S. mutans for 48 h. One cavity of each tooth was used to evaluate the infection. Following inoculation, infected cavity surfaces were treated either with (1) Er:YAG Laser (1W; 5x5s, Smart 2940D Plus, Deka Laser), (2) Ozone (80s; HealOzone, Kavo), (3) ErYAG-Ozone combination, (4) Er:YAG-Ozone-CHX combination, (5) Chlorhexidine (CHX), (6) Clearfil Protect Bond (PB), (7) potassium-titanyl-phosphate (KTP) Laser (1W; 60 s, SMARTLITE D, Deka Laser), (8) KTP-Ozone combination, and (9) KTP-Ozone-CHX. Standardized amounts of dentin chips were obtained from the cavity walls, and the number of bacteria recovered was counted. Kruskal-Wallis test was used for statistical analyzes. Results: Both sole antibacterial materials, CHX or Protect Bond application, exhibited the most effective antibacterial activity with 125 and 156 CFU is an acronym of "colony forming unit" usullay mentioned by acronym. (CFU/ml), respectively, among the groups evaluated (P < 0.05). Er:YAG laser irradiation and its combinations with other antibacterial surface pretreatment applications also inhibited the bacterial growth with, respectively, 1444, 406, and 294 CFU/ml bacterial recovery being more efficient than KTP laser irradiation and ozone combinations. Conclusions: As an alternative device with photodynamic effects, Er:YAG and KTP laser irradiations and their further combinations during the cavity pretreatment procedure with chlorhexidine and ozone treatments exerted antibacterial effect against S. mutans, whereas chlorhexidine and antibacterial dentin bonding application solely have the highest antibacterial effects.

RESUMO

AIM: To compare the pre-sterilization cleaning of rotary Ni-Ti files of different sizes previously used a. ex vivo and b. clinically by a washer-disinfector, a regular ultrasonic bath, and the same ultrasonic bath in combination with a recently developed cavitation intensifying method. METHODOLOGY: Two sets of two hundred rotary Ni-Ti files, one previously used ex vivo and another one used clinically, were collected from the undergraduate and postgraduate clinics of the Academic Centre for Dentistry Amsterdam (ACTA). The instruments were immersed in an enzymatic solution and subsequently cleaned either by a washer-disinfector, a regular ultrasonic bath combined with a glass beaker, the same bath combined with a beaker lined with two cavitation intensifying sheets or with two standard plastic sheets. The positive control consisted of used files that did not undergo any cleaning and the negative control included new unused files. The instruments were then stained to reveal remaining protein material and scored under a stereoscopic microscope. The results were analysed by nonparametric statistical tests (α = 0.05). RESULTS: No significant difference was found between the combination of the ultrasonic bath and the regular glass beaker and the same ultrasonic bath with the beaker lined with the cavitation intensifying sheets. The washer-disinfector left significantly more debris compared to the latter group when clinically used files were evaluated (P ≤ 0.001). The effect of instrument size on cleaning was not consistent. CONCLUSION: None of the tested methods was able to remove all residual protein material from the files; however, it could be noted that this study did not follow the reprocessing protocol provided by the manufacturer.

RESUMO

Detonation nanodiamonds (NDs) are promising drug delivery and imaging agents due to their uniquely faceted surfaces with diverse chemical groups, electrostatic properties, and biocompatibility. Based on the potential to harness ND properties to clinically address a broad range of disease indications, this work reports the in-human administration of NDs through the development of ND-embedded gutta percha (NDGP), a thermoplastic biomaterial that addresses reinfection and bone loss following root canal therapy (RCT). RCT served as the first clinical indication for NDs since the procedure sites involved nearby circulation, localized administration, and image-guided treatment progress monitoring, which are analogous to many clinical indications. This randomized, single-blind interventional treatment study evaluated NDGP equivalence with unmodified GP. This progress report assessed one control-arm and three treatment-arm patients. At 3-mo and 6-mo follow-up appointments, no adverse events were observed, and lesion healing was confirmed in the NDGP-treated patients. Therefore, this study is a foundation for the continued clinical translation of NDs and other nanomaterials for a broad spectrum of applications.

RESUMO

Introducción: en los procedimientos odontológicos se está expuestoa gran cantidad de microorganismos y las intervenciones clínicas provocan un contacto directo o indirecto con éstos, ya sea a través del instrumental, equipo odontológico contaminado con saliva, sangre, exudados, etcétera. Por esta razón debe tomarse en cuenta el tipo de contaminación de las piezas de mano por ser parte del equipo de uso cotidiano para realizar tratamientos odontológicos. Objetivos generales:Determinar la carga bacteriana en las piezas de alta velocidad antes y después de su uso en diferentes clínicas de la Facultad de Odontologíade la UV Región Veracruz. Metodología: Investigación transversal, descriptiva y observacional. Material y métodos: Se seleccionaron al azar 30 piezas de mano de los estudiantes de la Universidad Veracruzana Facultad de Odontología Región Veracruz, a las cuales se tomó una muestra con un hisopo de algodón antes y después de su uso en la práctica dental. Se realizaron cultivos con las muestras obtenidas que se observaron durante tres días seguidos bajo microscopio para comprobar la presencia de colonias bacterianas. Resultados: De las30 piezas antes de ser utilizadas se detectó Bacillus grampositivos en24 por ciento de las muestras; en 20 por ciento Bacillus gramnegativos, en 6 por ciento Streptobacillus gram-positivos; en 20 por ciento Staphylococcus grampositivos; en 3 por ciento Cocobacillus gramnegativos y en 22 por ciento Actinomyces gramnegativos. El restante 2 por ciento no reveló unidades formadoras de colonias (UFC). En un segundo muestreo, 33 por ciento desarrolló Bacillus grampositivos, 10 por cientoBacillus gramnegativos, 20 por ciento adquirió Sthapylococcus grampositivos, 3 por ciento Sthapylococcus gramnegativo y 34 por ciento no reveló UFC. Conclusión:En el primer muestreo se detectaron microorganismos en 98% de laspiezas de mano, mientras que en el segundo muestreo 66% se contaminócon microorganismos y en 34% no se observó contaminación.


Introduction: dental activity is exposed to a lot of microorganisms,and clinical interventions have a direct or indirect contact with them.Whether through the instruments, dental equipment contaminatedwith saliva, blood, etc; so you should take into account the type ofcontamination of handpieces for being the most widely used equipmentfor dental treatment. General Objectives: Determine the bacterialload in high-speed parts before and after being used in diff erentclinical uses in Dentistry School at UV, Veracruz. Methodology:Cross-sectional, descriptive and observational research. Materialand methods: 30 pieces of students from the Universidad VeracruzanaSchool of Dentistry, Veracruz region, which a sample was takenwith a swab to pieces before and after use in dental practice wererandomly selected. Cultures with samples obtained observedduring three days in a row microscope to determine the presenceof bacterial colonies were made. Results: Of the 30 pieces beforebeing used 24% of Bacillus Gram-positive samples were found; 20%Bacillus Gram-negative, Gram-positive Streptobacillus 6%; 20%Gram-positive Staphylococcus, 3% developed Coccobacillus Gramnegativeand 22% Gram negative Actinomyces. The remaining 2%no colony forming units development (UFC). In a second sampling;33% developed Bacillus Gram-positive, Gram-negative Bacillus10%, 20% obtained Sthapylococcus Gram-positive, Gram-negativeSthapylococcus 3% and 34% did not develop colony forming unit(CFU). Conclusion: In the first sampling 98% of the pieces were microorganism growth, while in the second 66% and the presence ofmicroorganisms obtained 34% no development.

RESUMO

O maior obstáculo para o sucesso do tratamento endodôntico é a eliminação da microbiota instalada. A instrumentação mecânica, bem como as substâncias químicas auxiliares, é utilizada para eliminação dessa microbiota. Além das soluções irrigantes, outras técnicas complementares, como a agitação ultrassônica passiva (PUI) e o laser, estão sendo utilizadas para otimizar a eliminação dos microrganismos. Desse modo, o presente estudo objetivou o levantamento bibliográfico de diferentes tipos de agitação dos irrigantes no tratamento endodôntico. A PUI tem sido sugerida como um meio para melhorar o desbridamento do canal. Já o laser tem sido utilizado por apresentar vantagens terapêuticas ao tratamento. Todas as técnicas citadas para melhorar a limpeza dos canais radiculares mostraram alguma melhora. A técnica mais empregada ainda é a agitação ultrassônica, por apresentar eficiência e praticidade no procedimento. Pôde-se concluir que a diminuição da microbiota é mais eficiente quando se utiliza uma maior concentração da solução irrigadora, independentemente da agitação final de escolha.

RESUMO

Las medidas de bioseguridad están predestinadas a reducir el riesgo de transmisión de microorganismos a partir de fuentes de infección reconocidas o no reconocidas en clínicas dentales vinculadas con lacontaminación de los materiales, aparatos y/o instrumentos. Un microorganismo reemergente es el Mycobacterium abscessus, que es unabacteria ambiental que puede ocasionar problemas de salud muy serios, por lo que debe ser controlada y prevenida su transmisión.


Biosafety measures are designed to reduce the risk of transmission ofmicroorganisms from recognized or unrecognized sources of infectionin dental procedures associated with the contamination of materials,apparatus, and/or instruments. One reemerging microorganism isMycobacterium abscessus, which is an environmental bacterium thatcan cause serious health problems and therefore needs to be controlledand prevented.

RESUMO

Oral health caring in hospitalized patients is very important, considering the risks of complications that non disinfection of oral cavity can cause to your general health. Several risk of periodontal disease associations have been described in the literature, such as nosocomial pneumonia and cardiovascular disorders, among others. The introduction of oral hygiene protocols in hospitalized patients has been recommended by the simplicity and the potential they represent in preventing some systemic stages. The objective of this study was to apply the adjusted protocol oral hygiene in patients admitted to the Intensive Care Cento (ICU) of the Hospital Universitário Sul Fluminense (HUSF), Vassouras-RJ to improve the quality of dental care for hospitalized patients, preventing so its systemic complications of health. The disinfection of the oral cavity was made by the introduction of the use of 0.12% chlorhexidine gluconate, as well as proper oral hygiene instruction. Nursing professionals (students, assistants and technicians) were invited to participate in the project using the mouthwash (PerioPlak, Reymer) for routine and effective use in the prevention of oral infections. A comparison was conducted using two graphs showed a decrease of 0.44% in the number of mechanical ventilation infection from the use of the oral care protocol. It is concluded that it is extremely important the presence of a dentist in intensive care units to take care of the oral health of patients thus preventing risks of infection due to their health status (AU)


O cuidado com a saúde bucal em pacientes internados é muito importante, considerando os riscos de complicações que a não desinfecção da cavidade bucal possa causar no seu estado de saúde geral. Várias associações de risco da doença periodontal foram descritas na literatura, tais como alterações cardiovasculares e pneumonia nosocomial, dentre outras. A introdução de protocolos de higiene bucal em pacientes internados tem sido recomendada pela simplicidade e pelo potencial que representam na prevenção de alguns quadros sistêmicos. O objetivo deste trabalho foi aplicar o protocolo de higiene bucal em pacientes internados no Cento de Terapia Intensiva (CTI) do hospital Universitário Sul Fluminense (HUSF), Vassouras-RJ, visando melhorar a qualidade de atenção em saúde bucal ao paciente hospitalizado, prevenindo assim complicações do seu estado sistêmico de saúde. A desinfecção da cavidade bucal foi feita através da instituição do uso de gluconato de clorexidina a 0,12%, assim como instrução de higiene bucal adequada. Os profissionais da área de enfermagem (estudantes, auxiliares e técnicos) foram convidados a participar do projeto sendo disponibilizado o enxaguatório bucal (PerioPlak, REYMER) para uso rotineiro e efetivo na prevenção de infecções bucais. Foi realizado um comparativo através de dois gráficos que mostrou uma redução em 0,44% do número de infecção por ventilação mecânica a partir da utilização do protocolo de higiene bucal. Conclui-se que é de extrema importância a presença de um cirurgião-dentista nas unidades de terapia intensiva para cuidar da saúde bucal dos pacientes prevenindo assim riscos de infecções devido a seu estado de saúde (AU)
