Effects of cold spray on thirst, frequency of oral care, and pain of general surgery intensive care unit patients.

This study aims to investigate the effects of intraoral cold water spray on thirst, frequency of oral care and postoperative period pain at surgical incision site in patients having abdominal surgery. The study was carried out as a randomized controlled trial, registered under Clinical Trial Number: NCT05940818. The study involved 110 participants, divided equally into two groups (n = 55): the experimental group and the control group. Data were collected using patient information form, NRS, Intensive Care Oral Care Frequency Assessment Scale (ICOCFAS) and Visual Analog Scale (VAS). The severity of thirst at 1st, 8th, 16th h of post-operative period (p < 0.01) and the frequency of oral care application at 16th h were statistically significantly decreased in the experimental group when compared to the control group (p < 0.01).There wasn't statistically significant difference between the patients in the experimental and control groups in terms of pain at surgical incision site (p > 0.05). The patient's thirst and need for frequent oral care in the postoperative period were reduced by the application of a cold water spray. In patients undergoing abdominal surgery, the use of cold water spray application may be recommended to reduce thirst and the need for frequency of oral care application.

Decision-making on peri-implant mucositis management and treatment approaches.

Peri-implant mucositis is characterised by inflammation of soft tissues surrounding a dental implant without associated bone loss beyond initial remodelling. Early detection and timely intervention are critical to prevent its progression to peri-implantitis. This paper focuses on various treatment options for treating peri-implant mucositis. The cornerstone of professional treatment lies in the mechanical disruption and removal of microbial biofilms around the implant. This can be achieved through careful use of manual or powered instruments, such as ultrasonic scalers or air polishing devices. However, there is a need for further research to determine the most effective single approach for treating peri-implant mucositis. Current evidence does not support the combination of mechanical debridement with locally administered antibiotics. Contrarily, evidence strongly supports the removal, cleaning, and modifications of prostheses to improve both self-performance and professional cleanability. The use of adjunctive therapies like photodynamic therapy and diode laser, in conjunction with mechanical instrumentation, is not currently recommended due to the limited strength of available evidence. Preventive measures emphasise the importance of comprehensive oral hygiene care, encompassing professional guidance and at-home practices, to manage biofilms effectively. This encompasses oral hygiene instruction, regular debridement, and maintenance care. Supporting peri-implant therapy is also vital for ongoing implant monitoring, preventing the recurrence of mucositis, and halting its progression to peri-implantitis. This multifaceted approach is key to effectively managing and treating peri-implant mucositis.

Antineoplastic therapy is an independent risk factor for dental caries in childhood cancer patients: a retrospective cohort study.

PURPOSE: To evaluate the antineoplastic therapy (AT) as a risk factor for dental caries lesions independent of other risk factors such as income, family education, stimulated salivary flow rate, hygiene habits, frequency of sugar intake, and microbiota in childhood cancer (CC) patients. METHODS: 72 individuals were divided into CC patients (n=36) and healthy individuals (control group - CT n=36). Demographic data, hygiene habits, frequency of sugar intake, CC type, and AT were collected. Stimulated salivary flow rate was measured and the presence and concentration of Streptococcus mutans were assessed using a real-time polymerase chain reaction (qPCR) technique. Clinical evaluations included plaque index (PI) and decayed-missing-filled-teeth index (dmft/DMFT). Descriptive statistics, T-test, Mann-Whitney test, chi-square test, Fisher's exact test, and two-way analysis of variance were used for data analysis (p<0.05). RESULTS: At the time of oral evaluation, both groups exhibited similar ages with means of 12.0±3.9 years old for CC and 12.0±4.0 years old for CT patients. All CC patients underwent chemotherapy with nine also undergoing radiotherapy. Significant differences were observed between the groups in terms of color/race, income, family education, and hygiene habits. However, no statistically significant differences were found between groups regarding the frequency of sugar intake, stimulated salivary flow rate, or the concentration of Streptococcus mutans (qPCR technique). For clinical parameters, the DMF (CC:1.80, CT: 0.75), decayed (CC: 0.88, CT: 0.19), missing (CC: 0.25, CT:0), and PI (CC: 30.5%, CT: 22.6%) were higher in the CC group (p<0.05). CONCLUSION: Childhood cancer (CC) patients undergoing antineoplastic therapy (AT) exhibit a higher prevalence of dental caries, regardless of income/education, frequency of sugar intake, stimulated salivary flow rate, and microbiota.

Periodontal disease prevalence and oral hygiene status of adults with cystic fibrosis: A case-control study.

AIM: To investigate the prevalence of gingivitis and periodontitis, and the oral hygiene status of adults with cystic fibrosis (CF) in the Republic of Ireland. MATERIALS AND METHODS: A case-control study in the form of a clinical examination of 92 adults with a diagnosis of CF was carried out in the adult CF unit in Cork University Hospital. A 40-item questionnaire was used to capture socio-demographic variables and medical and dental information. Two calibrated examiners carried out a periodontal assessment on participants, using the WHO-recommended CPI-modified index, and oral hygiene status was measured using the Greene-Vermillion index. The results were compared with a population-based control group of similar socio-demographic profile. RESULTS: Oral hygiene levels (plaque and calculus) were significantly worse in people with CF, with a median plaque index of 0.83 (interquartile range [IQR] 0.333-1.542) in the CF group compared with 0.5 (IQR 0.167-0.667) in the non-CF group. Calculus index in the CF group was 0.33 (IQR 0.17-0.83) compared with 0.33 (IQR 0.125-0.33) in the non-CF group. However, periodontal disease levels were significantly lower in the CF group. Gingivitis (bleeding on probing ≥ 10% sites) was seen in 67.4% of the CF group, compared with 83.7% of the non-CF group, OR 0.365 (95% confidence interval [CI] 0.181-0.736), relative risk (RR) 0.779 (95% CI 0.655-0.928). Mild periodontitis (periodontal probing depth [PPD] < 5 mm) was seen in 15.2% of the CF group, compared with 31.5% of the non-CF group, OR 0.390 (CI 0.190-0.800), RR 0.483 (95% CI 0.273-0.852). Severe periodontitis (PPD ≥ 6 mm) was seen in 0% of the CF group, compared with 9.8% of the non-CF group. There was a tendency, albeit non-significant, towards reduced periodontitis in PWCF who regularly took antibiotics, particularly azithromycin. CONCLUSIONS: In this study, adults with CF had poor oral hygiene practices, with high levels of plaque and calculus. Despite this finding, adults with CF had lower levels of clinical gingivitis and periodontitis than seen in a non-CF control group. Further study is required to examine the causes of this phenomenon.

Is there an association between oral hygiene and head and neck cancer?

DATA SOURCES: PubMed, Web of Science, the Cochrane Library and Embase were utilised as databases from inception till November 2021. STUDY SELECTION: The inclusion criteria consisted of cohort and case-control studies published in the English language, which dealt with diagnosed cases of head and neck cancer reporting survival, oral hygiene and comparative data. Studies pertaining to animal experiments along with case reports, conference proceedings, reviews, letters, editorials, errata and protocols were excluded. DATA EXTRACTION AND SYNTHESIS: Data such as publication year, authors' names, country, sources, study groups, age, gender, participant number, education, alcohol, tobacco, study quality, cancer site and outcomes were extracted for each included study. A modified Newcastle-Ottawa Scale was utilized to evaluate the quality of these studies. RESULTS: A total of forty-four studies were included, of which forty were case-control and four were cohort in nature. These comprised of a total of 52,863 patients of which 33,000 were devoid of head and neck cancer (HNC) while, 19,863 had a confirmed diagnosis of HNC. Oral hygiene and HNC were found to be associated. CONCLUSIONS: Poor oral hygiene was concluded to be associated with HNC and the subsites thereof.

Theory-derived intervention to improve oral health of older adults: study protocol for a randomised controlled trial.

INTRODUCTION: Changing health behaviours is an important and difficult task. Despite growing interest in behavioural theories and models, there is a paucity of research examining their validity in explaining oral health behaviours, and there is a need for interventional studies to assess their effectiveness in improving oral health. This study aims to test the explanatory power of the dominant psychological theories, develop theory-derived intervention and evaluate its effectiveness in improving oral health of older adults. METHODS AND ANALYSIS: 440 community dwelling older adults will be recruited. To be eligible for this trial, one needs to be 55-79 years old, having at least 8 natural teeth, and with no life-threatening disease, impaired cognitive function, or radiotherapy in the head and neck region. At the initial visit, each participant will be required to complete a detailed questionnaire which collects information on sociodemographic background, oral health behaviours and domains of three psychological theories and models: (1) health belief model, (2) theory of planned behaviour and (3) social cognitive theory. The theory or model that best explains the health behaviours will be selected for designing the oral health intervention. The effectiveness of the theory-derived intervention will be evaluated in a randomised controlled trial. Participants will be randomly assigned to two groups, receiving theory-derived intervention and conventional health education, respectively. At baseline and at 12 and 24 months post intervention, each participant will complete a short questionnaire and undergo an oral examination (dental check-up). The effectiveness of the interventions will be evaluated using behavioural outcomes (diet, toothbrushing, interdental cleaning) and clinical outcomes (oral hygiene, dental caries and periodontal conditions). ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board of National University of Singapore (Ref: NUS-IRB-2020-417). Findings will be presented in international conferences and peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04946292.

[Effect of a Simple Home-Based Oral Care Regimen on Oral Mucositis in Patients With Oral Cavity and Nasopharyngeal Cancer: A Quasi-Experimental Study].

BACKGROUND: The majority of patients with oral cavity and nasopharyngeal cancer experience severe oral mucositis during concurrent radiochemotherapy. The effectiveness of routine nursing education remains limited. PURPOSE: To evaluate the effect of a simple home-based oral care regimen on oral mucositis. METHODS: A double-group quasi-experimental design was adopted in this study. The participants were all newly diagnosed patients with oral cavity and nasopharyngeal cancer who were scheduled to receive concurrent radiochemotherapy in a northern medical center. A total of 31 patients in the experimental group and 32 patients in the control group were enrolled as participants. The control group received routine care, while the experimental group received an additional six- to seven-week two-way interactive home-based oral care regimen. The measurement tools included a plaque record and oral assessment guide (OAG) implemented twice during the study period. Study data were collected at 8 time points, including before treatment, at 1-5 weeks of treatment, at the end of treatment, and at one-month post-treatment. Data analysis was performed using two-way repeated measures ANCOVA. RESULTS: After controlling for OAG score, nutrition, age, living habits, and oral hygiene, the development of mucositis was found to be significantly slower in the experimental group than in the control group during the traumatic phase (effect of group: F = 11.1, p < .01; effect of group x time: F = 3.5, p = .01). However, both groups reported a statistically similar rate of improvement during the repair phase (effect of group and group x time: F = 0.19, p = .67). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The simple home-based oral care regimen introduced in this study may be used to improve traumatic oral mucositis in patients with oral cavity and nasopharyngeal cancer. It is recommended that even after the completion of radiotherapy, medical staffs should continue to strengthen patients' execution of proper oral care to maintain the positive effect until the mucositis has abated.

Efficacy of 3% hydrogen peroxide solution in cleaning tongue coating before and after surgery: a randomized phase II study.

BACKGROUND: Increased bacterial presence in the tongue coating and thereby, the saliva, may be a risk factor for postoperative complications such as surgical site infection or postoperative pneumonia after cancer surgery. However, no method for cleaning tongue coating has been established experimentally. The purpose of this study was to verify the effect of brushing with 3% hydrogen peroxide on suppression of the number of bacteria in tongue coating. METHODS: Sixteen patients with gastric cancer or colorectal cancer undergoing surgery were randomly allocated to control and intervention groups. In the control group, the tongue was brushed for 30 s with a water-moistened toothbrush, while in the intervention group, the tongue was brushed for 30 s with a toothbrush moistened with 3% hydrogen peroxide. Bacterial counts on tongue coating were measured before and 30 s after cleaning the tongue coating using the Rapid Oral Bacteria Quantification System. RESULTS: In the control group, the number of bacteria on the tongue did not decrease significantly after tongue cleaning on the day before surgery, but did on the day after surgery. In contrast, in the intervention group, the number of bacteria on the tongue decreased significantly after tongue cleaning both on the day before and the day after surgery. Furthermore, when comparing the control and intervention groups, the intervention group had a greater reduction effect. CONCLUSIONS: Tongue brushing with 3% hydrogen peroxide is a useful method to reduce the number of bacteria on the tongue in patients with gastrointestinal cancer undergoing surgery.

The Clinical Pattern and Prevalence of Streptococcus mutans and Streptococcus sobrinus among Adult and Children Patients with Dental Caries

Abstract Objective: To explore the clinical pattern, host factors, and presentation of Streptococcus mutans related to caries incidence among children and adults visiting Universitas Airlangga dental clinic. Material and Methods: This was an observational study with a cross-sectional approach with 50 patients in each group of carious children (6-12 years) and adults (18-35 years). Dental decay samples were taken by sterile excavator, put in a BHI's transport medium, and directly incubated overnight at 37 ºC. The next day, they were sub-cultured microbiologically in Tryptone Yeast Cystine Sucrose Bacitracin (TYCSB) selective medium. Bacterial species and serogroups were examined by PCR. All patient's data were collected from medical records and direct observation. Results: Caries were mostly media type in both children and adults. Oral hygiene (OHIS) in children was higher than in adults but not significantly different according to their DMFT. The highest scores for decay, missed and filled teeth were 16, 8 and 7, with an average of 6.82, 1.22 and 0.63, considered quite high. Conclusion: The prevalence of S. mutans was higher in children's caries than in adults, but among the adult patients the co-incidence of S. mutans and S. sobrinus was associated with higher DMFT. The mutans serotypes e, f, and d were more prevalent among children than adults.

Effects of Fixed and Removable Space Maintainers on Dental Plaque and DMFT/dft Values / Efecto de los mantenedores de espacio fijos y removibles en la placa dental y en los valores de los índices DMFT/dft

ABSTRACT: Purpose: Space maintainers are important for the health and placement of children's primary and permanent teeth. However, plaque and caries levels can be negatively affected when a dental appliance is in the mouth. This study aims to evaluate the oral health of pediatric patients that have space maintainers applied as a result of early tooth loss. Methods: This study included 100 systemically healthy patients between the ages of 4-15 years that were treated with space maintainers due to early loss of teeth. Decayed, missing, filled tooth index values and dental plaque status of the participants were recorded. Controls were performed in the 6th and 12th month. The index results were compared and evaluated statistically using ANOVA and paired-t-tests. Results: A total of 116 space maintainers, including 36 band and loops, 16 lingual arches, 21 palatal arches, 43 removable appliances, were evaluated in the study. Statistically significant differences were found between the pre-treatment and post-treatment index values (p<0.001). In the group of band and loops and removable space maintainers; the increases in DMFT/dft values of 6th month and 12th month according to initial DMFT/dft values were statistically significant (p<0.05). For plaque index, the increase in 12th month of all types of appliances were found statistically significant (p<0.001). The greatest increase in plaque index level was seen in the teeth of patients that had been treated with a lingual arch. Conclusions: Incompatible space maintainers can lead to caries, increased plaque accumulation, demineralized areas, and periodontal problems. The accumulation of plaque and difficulty of cleaning the teeth, especially in the fixed space maintainers, negatively affects the health of teeth. For this reason, good oral hygiene should be provided to patients and controls should be regularly performed.

RESUMEN: Los mantenedores de espacio son importantes para la salud y la colocación de la dentición primaria y permanente de los niños. Sin embargo, los niveles de placa y caries pueden verse afectados negativamente cuando se coloca un aparato dental en la boca. Este estudio tiene como objetivo evaluar la salud bucal de pacientes pediátricos a los que se les aplicó mantenedores de espacio como resultado de la pérdida temprana de los dientes. Métodos: Este estudio incluyó a 100 pacientes sistémicamente sanos entre las edades de 4 a 15 años que fueron tratados con mantenedores de espacio debido a la pérdida temprana de dientes. Se anotaron los valores del índice de dientes cariados, faltantes y el estado de la placa dental. Los controles se realizaron en el 6° y 12° mes. Los resultados del índice se compararon y evaluaron estadísticamente mediante ANOVA y pruebas t pareadas. Resultados: Un total de 116 mantenedores de espacio, incluyendo 36 bandas y bucles, 16 arcos linguales, 21 arcos palatinos, 43 dispositivos removibles, fueron evaluados en el estudio. Se encontraron diferencias estadísticamente significativas entre los valores de los índices en el pretratamiento y postratamiento (p<0.001). En el grupo de bandas, bucles y mantenedores de espacio removibles los aumentos en los valores de DMFT/ dft en el sexto mes y el 12º mes fueron estadísticamente significativos (p<0.05). Para el índice de placa, el aumento en el 12º mes de todos los tipos de aparatos se encontró estadísticamente significativo (p<0,001). El mayor aumento en el nivel del índice de placa se observó en los pacientes que habían sido tratados con un arco lingual. Conclusiones: los mantenedores de espacio pueden provocar caries, aumento de la acumulación de placa, áreas desmineralizadas y problemas periodontales. La acumulación de placa y la dificultad de limpiar los dientes, especialmente en los mantenedores de espacio fijos, afecta negativamente la salud dental. Por esta razón, se debe proporcionar una buena higiene bucal a los pacientes y se deben realizar controles regularmente.

Association between perioperative chlorhexidine oral care and postoperative pneumonia in non-cardiac surgical patients: A systematic review and meta-analysis.

BACKGROUND: Postoperative pneumonia is the third most common complication after surgery, and its occurrence is associated with a poor prognosis in patients. Perioperative chlorhexidine oral care has been reported to reduce the incidence of postoperative pneumonia in patients undergoing cardiac surgery. However, whether perioperative chlorhexidine oral care can reduce the incidence of postoperative pneumonia in noncardiac surgical patients is still unknown. The aim of this systematic review and meta-analysis was to determine the association between perioperative chlorhexidine oral care and postoperative pneumonia in noncardiac surgical patients. METHODS: A comprehensive systematic search of PubMed, Ovid Embase, Web of Science, the Cochrane Library, Wanfang Database, and the China National Knowledge Infrastructure was conducted to include studies from the inception of each database through March 2021. The reference lists of all included studies were also searched by hand. Eligible studies were published and unpublished randomized controlled trials and observational studies evaluating the effect of perioperative chlorhexidine oral care on the reported incidence of postoperative pneumonia. Relative risks or odds ratio with their 95% confidence intervals were calculated and risk of bias was assessed for eligible studies. RESULTS: Seven randomized controlled trials with a total of 1,773 patients and 3 observational studies with a total of 12,528 noncardiac surgical patients were included. A total of 621 and 5,904 patients received perioperative chlorhexidine oral care in randomized controlled trials and observational studies, respectively. Six (85%) randomized controlled trials had a high risk of bias, and 2 (67%) observational studies had a high quality. Perioperative chlorhexidine oral care significantly reduced the incidence of postoperative pneumonia in randomized controlled trials (relative risk, 0.60; 95% confidence interval, 0.44-0.80; P < .001) and observational studies (odds ratio, 0.26; 95% confidence interval, 0.08-0.90; P = .03). CONCLUSION: Perioperative chlorhexidine oral care led by a nurse significantly decreases the incidence of postoperative pneumonia in noncardiac surgical patients and may be more convenient and economical compared with dental professional-led perioperative oral care.

Caries en primeros molares permanentes y factores asociados a esta en escolares de Acapulco / Caries in permanent first molars and associated factors with its in schoolchildren from Acapulco

Introducción: La caries es una de las enfermedades bucodentales más frecuentes y, por ser las primeras en emerger, los primeros molares permanentes son las piezas más susceptibles a esta afección. Objetivo: Estimar la prevalencia de caries y factores asociados a esta en los primeros molares permanentes en escolares de segundo grado de primaria. Métodos: Estudio transversal, en estudiantes de segundo grado en 17 de 67 escuelas públicas de Acapulco, Guerrero. Un cuestionario autoadministrado se utilizó para obtener datos sociodemográficos y hábitos de higiene dental. La caries y la presencia de placa dentobacteriana se midieron a través de índices epidemiológicos, el CPOD (diente cariado, obturado y perdido) y el O'Leary. Se estimó la razón de momios e intervalo de confianza de 95 por ciento, ajustada por conglomerado, como medida de la fuerza de asociación mediante análisis multivariado. Resultados: Se revisaron 3332 primeros molares permanentes, el 21 por ciento tuvo caries, el 6 por ciento tuvo obturaciones y el 1 por ciento ya se había extraído. El índice CPOD de caries grupal fue 0,27. Cinco factores estuvieron asociados a la caries de los primeros molares permanentes: higiene dental deficiente (RMa = 2,87), técnica de cepillado dental inadecuada (RMa = 1,70), tomar alguna bebida dulce antes de ir a dormir (RMa = 1,68), visitar al dentista (RMa = 0,67) y aplicación de flúor (RMa = 0,61). Conclusiones: La prevalencia de caries en los primeros molares permanentes fue 21 por ciento dentro del rango reportado en otros estudios. Fueron identificados cinco factores asociados a la caries: higiene dental deficiente, técnica de cepillado inadecuado, consumo de azúcares antes de dormir, visitas al dentista y aplicación de flúor. Estos factores orientan sobre qué medidas preventivas se deben promover en los escolares para la preservación de sus piezas dentales(AU)

Introduction: Caries is the most frequent oral disease and the first permanent molars are very susceptible to this condition because they are the first teeth to emerge. Objective: To estimate the prevalence of caries its associated factors in the first permanent molars in second grade primary school children. Methods: A cross-sectional study was carried out in second grade students in 17 out of 67primary public schools in Acapulco, Guerrero. We applied a self-administered questionnaire to obtain sociodemographic data and dental hygiene habits. Caries and the presence of dentobacterial plaque were measured through epidemiological indices, CPOD (decayed, blocked and lost tooth) and O'Leary index. The odds ratio and 95 percent confidence interval, adjusted by cluster, were estimated as a measure of strength of association through multivariate analysis. Results: We reviewed 3 332 permanent first molars, 21 percent had cavities, 6 percent had seals and 1 percent had already been removed. The CPOD index of group caries was 0,27. We found five factors associated with caries of the first permanent molars: deficient dental hygiene (RMa=2,87), inadequate tooth brushing technique (RMa=1,70), drinking a sweet drink before bedtime (RMa=1,68), visiting the dentist (RMa=0,67) and fluoride application (RMa=0,61). Conclusions: Prevalence of caries in the first permanent molars was 21 percent, within the range reported in other studies. Five factors associated with caries were identified: poor dental hygiene, inadequate brushing technique, consumption of sugars before going to sleep, visits to the dentist and application of fluoride. These factors guide what preventive measures should be promoted in schoolchildren for the preservation of their teeth(AU)

Oral peroxidases: From antimicrobial agents to ecological actors (Review).

Sialoperoxidase and myeloperoxidase are the two main peroxidase enzymes found in the oral cavity. Sialoperoxidase is present in salivary secretions and in the biofilms that line the oral surfaces, while myeloperoxidase is abundant in the dento­gingival sulcus area. In the presence of hydrogen peroxide (H2O2), oral peroxidases catalyze the oxidation of the pseudohalide anion thiocyanate (SCN­) to hypothiocyanite (OSCN­), a strong oxidant that serves an antimicrobial role. Furthermore, oral peroxidases consume bacteria­produced H2O2 and could help inactivate toxic carcinogenic and genotoxic substances. Numerous in vitro studies have reported the antibacterial, antimycotic and antiviral role of peroxidases, suggesting possible applications in oral therapy. However, the use of oral hygiene products incorporating peroxidase systems has not yet been shown to be beneficial for the treatment or prevention of oral infections. This paradox reflects our incomplete knowledge of the physiological role of peroxidases in a complex environment, such as the oral region. While hygiene is crucial for restoring oral microbiota to a symbiotic state, there are no data to suggest that the addition of a peroxidase per se can create a dysbiotic state. Recent investigations have associated the presence of peroxidase activity with gram­positive cocci microbial flora, and its insufficiency with dysbiosis has been linked to pathologies, such as caries, periodontitis or infections of the oral mucosa. Therefore, oxidants generated by oral peroxidases appear to be an essential ecological determinant for oral health through the selection of a symbiotic microbiota capable of resisting oxidative stress. The objective of the present review was to update the current knowledge of the physiological aspects and applications of oral peroxidases in clinical practice.

Resistance to Preoperative Oral Care Is Associated With Postoperative Pneumonia After Oesophageal Cancer Surgery.

BACKGROUND/AIM: Postoperative pneumonia is a serious complication of major oesophageal surgery. We aimed to clarify the association between the degree of improvement in oral hygiene by perioperative oral care and postoperative pneumonia in oesophageal cancer patients. PATIENTS AND METHODS: Oesophageal cancer patients (n=129) who underwent esophagectomy received perioperative oral care. Their oral hygiene was evaluated using the Oral Assessment Guide (OAG). The relationship between perioperative OAG scores and postoperative complications was analysed. RESULTS: The average OAG scores before starting oral care, pre-operation, and post-operation were 11.0±1.7, 9.1±1.5, and 11.2±3.0, respectively (p<0.001). An increase in preoperative OAG scores was independently associated with postoperative pneumonia on multivariate analysis (p=0.027). CONCLUSION: Preoperative oral care improves oral hygiene in patients undergoing oesophageal cancer surgery. No improvement in oral hygiene despite preoperative oral care was an independent predictor of postoperative pneumonia.

Effects of preoperative dental examination and oral hygiene instruction on surgical site infection after hepatectomy: a retrospective study.

PURPOSE: This study retrospectively investigated relationships among risk factors and post-hepatectomy surgical site infection (SSI) and other complications in patients who underwent hepatectomy for hepatocellular carcinoma (HCC). METHODS: We included 334 patients who underwent hepatectomies for liver cancers between January 2011 and December 2015 in this study. We evaluated risk factors for SSI and other post-hepatectomy complication, including demographic factors, preoperative factors, and preoperative intervention including oral management, perioperative factors, and length of hospital stay, with univariate and multivariate analyses. The oral management intervention included self-care instructions, extraction of infected teeth, removal of dental plaques and calculus (scaling), professional mechanical teeth cleaning, removal of tongue coating, and cleaning of dentures. SSI was defined in accordance with the guideline issued by the Centers for Disease Control and Prevention; it included purulent discharge from any incision or organ space within 30 days postoperatively, with or without microbiological evidence. Complications of grade II or greater, according to the Clavien-Dindo classification, were regarded as postoperative complications. RESULTS: We found bacterial infection of ascites (Odds ratio (OR) = 13.72), lack of preoperative oral management intervention (OR = 10.17), and severe liver fibrosis (OR = 2.76) to be associated with SSI and severe liver fibrosis (OR = 2.28), hypoalbuminemia (OR = 2.02), blood transfusion (OR = 1.86), and longer operation time (OR = 1.80) to be associated with postoperative complications. CONCLUSIONS: Preoperative oral management may reduce the risk of SSI in patients with HCC who undergo hepatectomy.

Protocolo de Higiene Oral para Establecimientos de Larga Estadía para Adultos Mayores en Estado de Pandemia COVID-19. Prevención de Neumonía por Aspiración / Oral Hygiene Protocol for Long-Term Establishments for Older Adults in a State of Pandemic COVID-19. Aspiration Pneumonia Prevention

RESUMEN: ¿Por qué es importante la salud oral en la prevención de enfermedades respiratorias en tiempos de pandemia? La razón es simple, cualquier enfermedad respiratoria en la persona mayor, podría eventualmente activar alarma de COVID-19 positivo, pudiendo ser esta ocasionada por otro motivo, sin mencionar el riesgo aumentado de tener una enfermedad previa de tipo respiratoria en tiempos de pandemia, sobre todo, en una población de riesgo como las personas mayores institucionalizadas. Por esta razón, la prevención en higiene oral de personas mayores mediante un Protocolo que proponga lineamientos a seguir en Establecimientos de Larga Estadía para Adultos Mayores, es fundamental en la prevención de Neumonía por aspiración. Cabe mencionar, que desde antes de surgir el COVID-19, ya la Neumonía se considera la principal causa de muerte por enfermedades infecciosas en la población chilena, y la primera causa específica de muerte en los mayores de 80 años.

ABSTRACT: Why is oral health important in the prevention of respiratory diseases in times of pandemic? The reason is simple, any respiratory disease in the elderly could eventually trigger a positive COVID-19 alarm, and this could be caused by another reason, not to mention the increased risk of having a previous respiratory-type illness in times of pandemic, over everything, in a population of risk like the institutionalized older people. For this reason, the prevention of oral hygiene in older people through a Protocol that proposes guidelines to be followed in long-stay establishments for older adults, is essential in the prevention of aspiration Pneumonia. It is worth mentioning that, before the emergence of COVID-19, Pneumonia was considered the main cause of death from infectious diseases in the Chilean population and the first specific cause of death in those over 80 years of age.

Relación entre factores socioeconómicos y salud bucal en estudiantes de una zona rural peruana / Socioeconomic factor in relation to oral health in students of a Peruvian rural area

ABSTRACT Introduction: The oral health of students from rural areas is a priority public health problem in Peru. Objective: To determine socioeconomic factors in relation to oral health in students from a rural Peruvian area. Methods: Descriptive cross-sectional observational study. The sample consisted of 604 students from a rural Peruvian area selected for convenience, meeting criteria of inclusion and exclusion, following ethical standards in scientific research. Socioeconomic factors were assessed using a structured questionnaire and the oral health using an epidemiological record with the indicators: DMFT index, Significant Caries Index (SiC), Simplified Oral Hygiene Index (OHI-S), Index of clinical consequences of untreated dental caries (PUFA). The evaluation was performed with natural light by calibrated observers. The data was analyzed in the program STATA 14 through frequency distribution tables and graphics. The relationship of each of the socioeconomic factors with the experience of dental caries was evaluated by the simple binary logistic regression tests. Results: The prevalence of dental caries was 85, 26 percent (DMFT = 6, 60 SiC=7, 23). The most frequent oral hygiene condition was regular, the prevalence of untreated tooth decay was 61.75 percent. Conclusions: The level of illiterate instruction, family responsibility and independent parental occupation showed a statistically significant association with their children's dental caries experience in a rural Peruvian area.

RESUMEN Introducción: La salud bucal de los estudiantes de zonas rurales es un problema prioritario de salud pública en el Perú. Objetivo: Determinar la relación entre factores socioeconómicos y salud bucal en estudiantes de una zona rural peruana. Métodos: Estudio observacional, descriptivo, de corte transversal. La muestra estuvo conformada por 604 estudiantes de una zona rural peruana, los que fueron seleccionados por conveniencia. Se evaluaron los factores socioeconómicos mediante un cuestionario estructurado y la salud bucal a través de una ficha epidemiológica con los indicadores: Índice CPOD, índice de significancia de caries dental (SIC), índice de higiene oral simplificado (IHO-S), índice de consecuencias clínicas de caries no tratadas (PUFA), la evaluación fue realizada con luz natural por observadores calibrados. Los datos se analizaron en el programa STATA v.14 mediante tablas de distribución de frecuencias y figuras. La relación de cada uno de los factores socioeconómicos con la experiencia de la caries dental se evaluó mediante pruebas de regresión logística binarias simples. Resultados: La prevalencia de caries dental fue de 85,26 por ciento (CPOD = 6,60, SIC = 7,23) y la prevalencia de caries dental no tratada fue 61,75 por ciento . La condición de higiene oral más frecuente fue regular. Conclusiones: El nivel de instrucción analfabeto, la responsabilidad familiar y la ocupación independiente de los padres mostraron asociación estadísticamente significativa con la experiencia de caries dental de sus hijos en un área rural peruana (p < 0,001)(AU)
