RESUMEN
BACKGROUND: Bariatric surgery can lead to short-mid-term vitamin deficiencies, but the long-term vitamin deficiencies is unclear. This study aimed to conduct a meta-analysis regarding the long-term prevalence (≥ 5 years) of vitamin deficiencies after bariatric surgery. METHODS: We searched the EMBASE, PubMed, and CENTRAL databases for clinical studies until June 2023. Meta-analysis, sensitivity, subgroup, and meta-regression analyses were performed. RESULTS: This meta-analysis included 54 articles with follow-up duration ranging from 5 to 17 years. The most prevalent vitamin deficiencies after surgery were vitamin D (35.8%), followed by vitamin E (16.5%), vitamin A (13.4%), vitamin K (9.6%), and vitamin B12 (8.5%). Subgroup analyses showed that the prevalence of vitamin A and folate deficiencies increased with the follow-up time. Roux-en-Y gastric bypass had a higher rate of vitamin B12 deficiency than sleeve gastrectomy and biliopancreatic diversion with duodenal switch (BPD-DS). Studies conducted in Europe had higher vitamin A deficiency (25.8%) than in America (0.8%); Asian studies had more vitamin B12 but less vitamin D deficiency than European and American studies. Meta-regression analysis displayed that publication year, study design, preoperative age, BMI, and quality assessment score were not associated with vitamin A, B12, D, and folate deficiencies rate. CONCLUSION: A high prevalence of vitamin deficiencies was found after bariatric surgery in the long-term follow-up, especially vitamin D, E, A, K, and B12. The variation in study regions, surgical procedures, and follow-up time are associated with different postoperative vitamin deficiencies; it is necessary to develop more targeted vitamin supplement programs.

AIMS: To generate pre-hospital symptom networks, explore core, bridge and sentinel symptoms, identify pre-hospital symptom clusters and analyse relationship between influencing factors and symptom clusters in decompensated cirrhosis patients. DESIGN: A cross-sectional study design using the Strengthening the Reporting of Observational Studies in Epidemiology checklist. METHODS: Demographical, physiological, psychological and sociological characteristics and the pre-hospital symptoms of 292 decompensated cirrhotic patients were collected from October 2021 to March 2023 in China. Frequencies, percentages, means, standard deviations, independent samples t-tests, one-way analysis of variance, exploratory factor analysis, multiple stepwise regression analysis and network analysis were used for data analysis. RESULTS: 'I don't look like myself' and itching were core and bridge symptoms, while bloating and lack of energy were sentinel symptoms in decompensated cirrhotic patients. Monthly family income, anxiety, depression, social support and disease duration influenced the neuropsychological symptom cluster, with worrying as the strongest predictor symptom. Influential factors for cirrhosis-specific symptom cluster included Child-Pugh class, monthly family income, disease duration, anxiety and depression, with itching being the strongest predictor symptom. Monthly family income, disease duration and depression were influential factors for gastrointestinal symptom cluster, with loss of appetite as the strongest predictor symptom. CONCLUSIONS: Neuropsychological, cirrhosis-specific and gastrointestinal symptom clusters were formed in decompensated cirrhotic patients. Through network analysis, direct connections between symptoms, symptom clusters and their influencing factors were revealed, thereby offering clinicians a foundation for effectively managing patients' pre-hospital symptoms. IMPACT: Decompensated cirrhosis patients commonly have multiple symptoms, while the management of pre-hospital symptoms is often suboptimal. This study identified neuropsychological, cirrhosis-specific, gastrointestinal symptom clusters and recognized core, bridge and sentinel symptoms in these patients. It also revealed the most prominent symptoms within each cluster. This provides insight into the hierarchy of symptoms, improving symptom management in decompensated cirrhosis. PATIENT AND PUBLIC INVOLVEMENT: There was no patient or public involvement.

WHAT IS KNOWN AND OBJECTIVE: Drug-induced neutropenia is the main reason for the dose limitation of docetaxel in patients with breast cancer. The area under the drug concentration-time curve (AUC) of docetaxel is associated with neutropenia. However, the optimal exposure to docetaxel for receiving postoperative adjuvant chemotherapy remains unclear. Therefore, we aimed to evaluate the relationship between the docetaxel AUC and neutropenia, identify potential influencing factors, and explore the best monitoring target for docetaxel when treating patients with early-stage breast cancer using a population pharmacokinetic (PopPK) model. METHODS: Docetaxel plasma concentration, demographics, clinical data, and related laboratory data were collected. PopPK analyses were performed using a nonlinear mixed-effect modelling program. The docetaxel AUC was determined using the maximum a posteriori Bayesian (MAPB) method. The docetaxel exposure-toxicity threshold measured from the AUC for neutropenia was determined using the receiver operating characteristic (ROC) curve. The correlation between docetaxel exposure and neutropenia was analysed using multivariable logistic regression. RESULTS: Among the 70 participants, 47 (67.1%) developed severe neutropenia. The PopPK analysis showed that the typical drug clearance (CL) rate was 37.4 L/h. Age was a significant covariate of CL rate, and aspartate aminotransferase and albumin levels were covariables of the volume of distribution. The multivariable regression analysis showed that AUC >3.0 mg.h/L (odds ratio [OR], 5.940; 95% confidence interval [CI], 1.693-20.843; P = 0.005), platinum use (OR, 0.156; 95% CI, 0.043-0.562; P = 0.005) and baseline haemoglobin level (OR, 0.938; 95% CI, 0.887-0.993; P = 0.027) were significant factors influencing the occurrence of grade 3/4 neutropenia. The AUC of first cycle may not predict the occurrence rates of grade 3/4 neutropenia in later cycles. WHAT IS NEW AND CONCLUSION: We developed a docetaxel PopPK model for patients with early-stage breast cancer. Age and AST and ALB levels were significant covariates. AUC estimated using the MAPB method can predict the toxicity of docetaxel in patients with breast cancer. Docetaxel AUC >3.0 mg.h/L, absence of platinum use and low baseline haemoglobin level were risk factors for docetaxel-induced grade 3/4 neutropenia. STUDY REGISTRATION: Chinese Clinical Trial Center Registry (ChiCTR2200056460).

AIMS: To examine the differences in decisional conflict, decision regret, self-stigma and quality of life among breast cancer survivors who chose different surgeries, as well as the effects of decisional conflict, decision regret and self-stigma on quality of life. DESIGN: Observational study. METHODS: Paper and online surveys were used to collect data from March to September 2020. The Chinese version of the Decisional Conflict Scale, Decision Regret Scale, Self-Stigma Form and Functional Assessment of Cancer Treatment-B were used to measure the corresponding health outcomes for breast cancer survivors who chose different surgeries from three university-affiliated hospitals. One-way analysis of variance, Pearson's correlation coefficient and hierarchical multiple regression analysis were used for data analysis. RESULTS: Among the 448 participants, only 21% chose breast conservative surgery, while 79% chose mastectomy with or without reconstruction. Women who chose mastectomy with reconstruction reported higher decisional conflict (p = .028) and more decision regret (p = .013) than women who chose breast conservative surgery; women who chose mastectomy without reconstruction indicated higher decisional conflict (p = .015), more decision regret (p < .001), and higher self-stigma (p = .034) than women who chose breast conservative surgery. Decisional conflict (r = -.430), decision regret (r = -.495), and self-stigma (r = -.561) were negatively correlated with quality of life. After controlling for sociodemographic and clinical variables, decisional conflict and decision regret explained 19.7% and self-stigma explained 12.9% of the variance in quality of life. CONCLUSION: Decisional conflict, decision regret and self-stigma vary according to different breast surgeries and are greatly associated with the quality of life of breast cancer survivors. IMPACT: Future studies are warranted to investigate the decision-making process and the underlying reasons for surgical choices. Decision support strategies pre-surgery are needed to inform women about the risks and benefits of surgery options. Moreover, psychosocial support post-surgery is warranted to relieve women's self-stigma, thus improving their quality of life.

The highly structured biofilms on the surface of internal tubing are regarded as the most important source of water pollution in the dental unit waterline (DUWL). Herein, the study aimed to evaluate the anti-biofilm effect of combined application of chlorine-containing disinfectant with multi-enzyme detergent in the dental unit waterline. Six dental units were included and randomly divided into two groups - Group A was treated with chlorine-containing disinfectant and multi-enzyme detergent; Group B was treated only with chlorine-containing disinfectant as control. All groups were treated once a day for four weeks. The anti-biofilm effect was evaluated by heterotrophic plate counts in output water, structure of biofilms, and fluorescence density of biofilms before and after treatment. Abundant opportunistic bacteria forming dense biofilms were observed before treatment. After one week, scanning electron microscopy showed the extracellular polymeric substance of biofilms in Group A was partially destroyed. The biofilms of Group A were completely removed in the third week, while the biofilms of Group B were still present. The combined application of chlorine-containing disinfectant and multi-enzyme detergent achieved a satisfactory effect on biofilms removal, demonstrating this strategy may play a significant role in reducing contamination in the dental clinic.

OBJECTIVES: To evaluate the effectiveness of a prevention strategy against the spread of SARS-CoV-2 infection among dental hospital staff over a 3-month period. MATERIALS AND METHODS: The effectiveness of the prevention strategy, which adopted healthcare staff protective measures, including patient triage and correct usage of personal preventive equipment, was evaluated by SARS-CoV-2 detection and serological testing. Patients who visited the Affiliated Stomatology Hospital, Zhejiang University School of Medicine, Hangzhou, China, between January 31 and March 1 (lockdown period) and March 2 and April 27 (reopening period) in 2020 and in the same period in 2019 were included in the study. Patients' diagnosis, age, gender, and several undergoing aerosol-generating procedures during the study period were collected from the hospital's database. Corresponding data were compared year-on-year (2020-on-2019). A total of 757 hospital staff underwent SARS-CoV-2 detection and serological testing on April 28-29, 2020. RESULTS: During the lockdown and reopening period in 2020, the number of hospital visits was dramatically decreased to about 6% and 58%, respectively, compared with the same period in 2019. However, emergency visits were increased 16- and 6.4-fold. A total of at least 6654 patients (13.58%) underwent aerosol-generating procedures during the study period in the year 2020. All hospital staff were negative according to SARS-CoV-2 detection and serological testing (IgG, IgM) data. CONCLUSION: During the study period in 2020, the total number of hospital visits dramatically reduced but emergency visits significantly increased. The prevention strategy implemented successfully prevented SARS-CoV-2 infection spread among healthcare workers in a dental hospital. CLINICAL RELEVANCE: The prevention strategy indicated patient triage and how to adopt preventive measures for controlling SARS-CoV-2 spread among healthcare workers. These data can be used as a reference for other sectors suffering from the COVID-19 pandemic.

Background: The biofilm formation in Dental Unit Waterlines (DUWLs) could become an important cause of infection during dental care, which could put immunocompromised individuals at risk of cross-infection. The aim of this study was to characterize the microbial communities of biofilms among DUWLs using high-throughput sequencing technology. Methods: Twenty-nine biofilm samples were obtained from 24 dental chair units at 5 hospitals and 2 dental clinics. The genomic DNA of the samples was extracted, then 16S rDNA and ITS2 gene were amplified and sequenced. Alpha-diversity and Beta-diversity were calculated with QIIME2 and the Kruskal - Wallis H-test was adopted for statistical analysis. Results: Microbial communities with a high diversity of bacteria (377 genera) and fungi (83 genera) were detected in the biofilm samples. The dominant phylum of bacteria was Proteobacteria (93.27%) and that of fungi was Basidiomycota (68.15%). Potential human pathogens were detected including 7 genera of bacteria (Pseudomonas, Stenotrophomonas, Hafnia-Obesumbacterium, Burkholderia-Caballeronia-Paraburkholderia, Ralstonia, Enterobacter, Klebsiella) and 6 genera of fungi (Malassezia, Candida, Alternaria, Cryptococcus, Rhodotorula, Rhinocladiella). Conclusions: This multicenter assessment revealed the infectious risk during dental care. It emphasized the importance of biofilm control due to biofilm accumulation and multiple kinds of opportunistic pathogens in DUWLs.
RESUMEN
Background: Obese patients with depression face higher risks of adverse events. However, depression is often misdiagnosed and undertreated in this group. This study aimed to identify predictors of depression and create a nomogram and calculator to assess depression risk in obese Americans. Methods: This cross-sectional study included 2674 patients from the National Health and Nutrition Examination Survey database (NHANES). These participants were randomly classified into the training and validation groups in a 7:3 ratio. Predictors were selected by LASSO and multivariate logistic regression analysis to create the nomogram. C-statistics, calibration plots, and decision curve analysis (DCA) were used to test the nomogram's discriminative ability, calibration quality, and clinical value. Internal validation with bootstrap resampling and external validation with the validation group were also conducted. Results: The training and validation group consists of 1871 and 803 participants. Depression was presented in 11.4 % (203/2674) of these participants. Seven predictors were found, including gender, hypertension, weekday sleep duration, poverty to income ratio, history of seeing mental health doctor, diabetes, and feeling sleepy during the day. The nomogram showed good discrimination, with the area under the receiver operating characteristic curve (AUC) of 0.817 (95 % CI: 0.786-0.848) (0.806 through internal validation and 0.772 through external validation) and good calibration (P = 0.536). The DCA further confirmed the nomogram's clinical usefulness. Conclusion: The nomogram and calculator effectively predict depression risk in obese Americans and can be used as auxiliary tools for early screening in primary care.
RESUMEN
OBJECTIVES: This study aimed to systematically evaluate the prevalence of dental anxiety in Chinese adults and to provide references for decision making on oral healthcare. METHODS: We searched PubMed, Web of Science, Ebsco, Embase, The Cochrane Library, WanFang Data, CNKI, and VIP database to collect cross-sectional studies on dental anxiety in Chinese adults from the establishment of the databases to 30 September 2022. After literature screening, data extraction, and evaluation of the risk of bias in the included studies by two researchers independently, R 4.0.4 software was used to perform a Meta-analysis. RESULTS: A total of 39 studies were included, including 24 309 subjects. Meta-analysis showed that the prevalence of dental anxiety in Chinese adults was 35.39% [95%CI (31.31%, 40.01%)]. Subgroup analysis showed that the prevalence rates of male and female adults were 32.92% and 44.78%, respectively. The prevalence rates of adults aged 16-39,40-59, ≥60 were 49.37%, 47.13%, and 37.41%, respectively. The prevalence rates of mild, moderate, and severe patients were 13.81%, 15.15%, and 9.24%, respectively. The prevalence rates of adults with elementary school and below, middle school, and university and above education levels were 33.81%, 35.84%, and 36.24%, respectively. The prevalence rates were 39.45% and 45.90% in adults with and without dental-treatment history, respectively. The prevalence rates of adults surveyed in dental and non-dental clinics were 27.10% and 39.31%, respectively. CONCLUSIONS: The prevalence of dental anxiety in Chinese adults was relatively high, primarily moderate anxiety, and it was more likely to occur in women, young people, and groups with no history of dental treatment. Early intervention should be performed for adults with dental anxiety to improve their awareness of oral healthcare and treatment compliance and thus to promote the oral-health level of adults in China.

BACKGROUND: The risk of protein and vitamin deficiencies after bariatric surgery has been well studied, but the change in mineral status has not gotten enough attention. This study aimed to perform a meta-analysis regarding the change in mineral levels after bariatric surgery and the prevalence of postoperative mineral deficiency, with subgroup analyses of different surgical procedures, study regions, and follow-up time. METHODS: CENTRAL, PubMed, and EMBASE were searched for related articles. Meta-analysis, subgroup analysis, and sensitivity analysis were performed if necessary. RESULTS: A total of 107 articles with 47,432 patients were included. The most severe mineral deficiency after bariatric surgery was iron (20.1%), followed by zinc (18.3%), copper (14.4%), chlorine (12.2%), phosphorus (7.5%), and calcium (7.4%). Serum concentrations of potassium, sodium, selenium, manganese, and molybdenum showed no significant change before and after surgery. Subgroup analyses revealed that SG had fewer deficiencies in serum iron, calcium, zinc, magnesium, phosphorus, copper, and selenium than RYGB. OAGB showed a higher incidence of serum iron and zinc deficiencies than RYGB. Studies conducted in different regions also found various mineral statuses after surgery. Studies with follow-up ≥ 5 years had a lower prevalence of zinc, copper, and selenium deficiencies than follow-up < 5 years. CONCLUSION: A high deficiency rate of serum iron, zinc, copper, chlorine, phosphorus, and calcium was seen after bariatric surgery. The difference in surgical procedures, study regions, and follow-up time may affect postoperative mineral status; more targeted mineral supplement programs are needed considering these influencing factors.

PURPOSE: This study aimed to investigate reproductive concerns among breast cancer patients of reproductive age, analyze the influencing factors, explore the relationship between coping styles, fear of progression (FOP), and reproductive concerns, and identify the multiple effects of coping styles on the relationship between FOP and reproductive concerns among Chinese breast cancer patients. METHODS: A cross-sectional, descriptive study was conducted among breast cancer patients in four tertiary grade A hospitals in Fujian, China, from January 2022 to September 2022. A total of 210 patients were recruited to complete paper-based questionnaires, which included the general data questionnaires, the Reproductive Concerns After Cancer Scale (RCACS), the Fear of Progression Questionnaire-Short Form (FOP-Q-SF), and the Medical Coping Modes Questionnaire (MCMQ). Structural equation models were utilized to evaluate the multiple effects of coping styles on FOP and reproductive concerns. RESULTS: Reproductive concerns in breast cancer patients had a mean score of 53.02 (SD, 10.69), out of a total score of 90, and coping styles for cancer (confrontation, avoidance) were closely associated with FOP and reproductive concerns. FOP showed a significant positive correlation with reproductive concerns (r = .52, p < .01). At the same time, confrontation was significantly negatively correlated with both FOP (r = -.28, p < .01) and reproductive concerns (r = -.39, p < .01). Avoidance was positively correlated to both FOP (r = .25, p < .01) and reproductive concerns (r = .34, p < .01). The impact of FOP on reproductive concerns is partially mediated by confrontation and avoidance, with effect sizes of .07 and .04, respectively. These mediating factors account for 22.0% of the total effect. CONCLUSIONS: The FOP directly impacted reproductive concerns, while coping styles could partially mediate the association between FOP and reproductive concerns. This study illustrates the role of confrontation and avoidance in alleviating reproductive concerns, suggesting that it is necessary to focus on the changes in reproductive concerns among reproductive-age breast cancer patients. Healthcare professionals can improve disease awareness and reduce patients' FOP, thereby promoting positive psychological and coping behaviors and ultimately alleviating reproductive concerns.

The contamination of dental unit waterlines (DUWLs) is a major health concern since it can pose cross-infection risks among dental professionals and their patients. Silver is one of the widely used metals in medical fields due to its superior antimicrobial properties. Silver-based agents have been commercially available for the decontamination of dental unit water currently. This systematic review aims to examine the evidence supporting efficacy and safety of application of silver to decontaminate DUWLs. We performed a search of the peer-review literature of studies in six electronic databases using corresponding search terms. Eligibility was restricted to English-language studies exploring the application of silver to decontaminate dental unit water, e.g., silver-based disinfectants and silver-coated dental waterlines tubing. The search identified 148 articles, and 9 articles that met the criteria were synthesized with qualitative narrative analyses. We observed good evidence of antimicrobial efficacy of silver with hydrogen peroxide on diverse microorganism present in DUWLs. Furthermore, there is insufficient evidence on the application of silver nanoparticles (AgNPs) as an efficient material to control the biofilms in DUWLs. Post-treatment data of either the bactericidal and bacteriostatic effects of silver or AgNPs, especially the actual clinical efficacy of long-term application, are scarce. More high-quality research is needed to resolve the gap on the optimal dosage and treatment options required to control bacterial and biofilm in DUWLs with silver-containing materials.

OBJECTIVES: The purpose of this study was to systematically assess the epidemic trend of periodontal disease in pregnancy. DATA: Eligibility criteria comprised studies that reported periodontitis and the periodontal indicators of BOP (+) or CAL≥4 mm or PD≥4 mm among pregnant women. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied where applicable. Risk of bias was assessed using the Critical Appraisal Checklist for prevalence studies proposed by The Joanna Briggs Institute (JBI). Meta-analyses were conducted to estimate the pooled effect measures. Q-statistic, I2 statistic, subgroup and sensitivity analyses assessed study heterogeneity. SOURCES: Electronic search of articles was conducted using PubMed, Web of Science, EMBASE, Scopus, and Ovid from January 2000 to January 2022. RESULTS: A total of 20 studies were included in the meta-analysis. The prevalence of periodontitis among pregnancy was 40% (95% Confidence Interval (CI): [0.15, 1.00]). The prevalence rates were 67% (CI [0.56, 0.80]), 42% (CI [0.27, 0.57]) and 24% (CI [0.12, 0.37]) for BOP (+), PD≥4 mm and CAL≥4 mm respectively. Regarding subgroup meta-analyses, the prevalence rates of BOP (+) and PD≥4 mm presented a gradual increase throughout pregnancy, while the highest prevalence rate of CAL≥4 mm was in the 2nd trimester. CONCLUSIONS: It was observed a high prevalence of periodontal disease in pregnancy. However, heterogeneity was high among included studies. More high-quality epidemiologic investigations on periodontal disease in pregnancy are still needed. CLINICAL SIGNIFICANCE: Periodontal disease in pregnancy is highly prevalent which results in a reduced quality of life, frequent systemic pathologies and adverse pregnancy outcomes. Given the unhealthy consequences, public health impact, and expansive disease burden, it is worthwhile to investigate more aspects of periodontal disease during pregnancy.

Background. Severe contamination of dental unit waterlines was found in healthcare settings. The benefits of decontamination methods are controversial. The aim of this review was to systematically evaluate disinfection methods in contamination control of dental unit waterlines.Methods. The terms 'dental unit waterline(s) or DUWL(s) or dental unit water line(s)' were searched through PubMed, Cochrane Library, Embase, Web of Science and Scopusup to 31 May 2021. The DUWLs' output water was incubated on R2A agar at 20-28 °C for 5-7 days to evaluate heterotrophic mesophilic bacteria. The risk of bias was evaluated by a modified Newcastle-Ottawa quality assessment scale.Results. Eighteen papers from the literature were included. One study indicated that water supply played a crucial role in disinfecting DUWLs. Three studies indicated that flushing decreased bacteria counts but did not meet the American CDC standard (500 c.f.u. ml-1). All chlorine- and peroxide-containing disinfectants except sodium hypochlorite in one of 15 studies as well as three mouthrinses and citrus botanical extract achieved the standard (≤500 c.f.u. ml-1). The included studies were of low (1/18), moderate (6/18) and high (11/18) quality.Conclusion. Independent water reservoirs are recommended for disinfecting DUWLs using distilled water. Flushing DUWLs should be combined with disinfections. Nearly all the chlorine-, chlorhexidine- and peroxide-containing disinfectants, mouthrinses and citrus botanical extract meet the standard for disinfecting DUWLs. Alkaline peroxide would lead to tube blockage in the DUWLs. Regularly changing disinfectants can reduce the risk of occurrence of disinfectant-resistant strains of microbes.

Background: Emergency gingival uncontrollable bleeding after nonsurgical periodontal therapy (NSPT) could be caused by a variety of factors; local oral factors are the main cause of gingival bleeding in most patients. Because the doctor will do a good job of evaluating the patient's physical condition before nonsurgical periodontal therapy. This study is subjected to evaluate the possible factors associated with emergency uncontrollable bleeding within 24-48 hours after NSPT. Material and Methods. A total of fifty-eight patients with emergency bleeding after NSPT in the past four years were enrolled. The related factors in patients, such as age, gender, clotting function, systemic diseases, and baseline periodontitis severity, were analyzed. The site-related factors, such as tooth type, tooth distribution, and alveolar bone resorption at the bleeding site, were compared. The possible relationship of the parameters to the causes of emergency bleeding with NSPT was also evaluated. Results: Gingival bleeding after NSPT was registered. In this retrospective study, a total of 58 patients were selected. There were 29 males and 29 females, aged from 20 to 67 years old, with an average age of 35.21 ± 10.09 years. Among them, 8.6% were over 50 years old, and 91.4% were under 50 years old. Completed evaluations were performed in 15.5% gingivitis and 84.5% periodontitis. The causes of emergency bleeding after nonsurgical periodontal therapy in this study were residual subgingival calculus or granulation tissue in 63.79% of cases: severe gingival inflammation, 29.32%; gum trauma, 3.45%; and poor compliance, 3.45%. The therapy method before bleeding includes supragingival scaling accounted for 72.4% and subgingival scaling accounted for 27.6%. 23 cases of horizontal absorption at the bleeding site accounted for 39.66%, and 35 cases of angular absorption accounted for 60.34%. Bleeding of maxillary posterior teeth accounted for 34.48%; mandibular anterior teeth accounted for 15.52%; mandibular anterior teeth accounted for 8.62%; and mandibular posterior teeth accounted for 18.97%; multiple sites accounted for 22.41%; eliminating residual subgingival calculus and granulation tissue were the main and most effective hemostatic methods, 86.21%. Conclusion: Residual subgingival calculus or granulation tissue and severe gingival inflammation were the main causes of emergency gingival bleeding after nonsurgical periodontal therapy. Severe gingival inflammation causing emergency bleeding was more common in maxillary posterior teeth areas. Angular alveolar bone resorption was more likely to cause bleeding than horizontal resorption. Careful debridement of residual subgingival calculus and granulation tissue was the main hemostatic method.
RESUMEN
Our study assessed the factors that influence the resistance of blood residues on dental surgical instruments to washer-disinfector-based cleaning procedures in a clinical setting. The use of 2 additional cleaning methods-presoaking and scrubbing by hand-and the use of newer and/or less structurally complex instruments significantly increased the efficacy of washer-disinfector cleaning.
