OBJECTIVE:Microvascular free flap reconstruction is the gold standard for head and neck defects, but flap compromise remains a primary cause of reconstructive failure. This study aims to evaluate the pooled incidence of flap compromise and total flap failure, and to identify risk factors to optimize perioperative management. DATA SOURCES:A systematic search was conducted across PubMed, MEDLINE, Embase, the Cochrane Library, and Web of Science for studies published up to September 1, 2025. REVIEW METHODS:This meta-analysis followed the PRISMA guidelines. Two independent reviewers screened the literature, extracted data, and assessed study quality using the Newcastle-Ottawa Scale (NOS). Random-effects models were used to calculate pooled incidences and odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS:Forty-seven studies involving 30,002 free flaps were included. The pooled incidence of flap compromise was 8.2% (95% CI: 6.6%-9.9%), with a complete failure rate of 3.9% (95% CI: 3.2%-4.7%). Flap compromise was significantly associated with prior radiotherapy (OR = 3.98). Other significant non-modifiable factors included diabetes (OR = 2.20), advanced age (OR = 1.35), and high comorbidity scores (OR = 1.68). Importantly, several modifiable factors were identified as critical drivers, including fluid overload (OR = 2.57), prolonged operative time (OR = 2.14), low serum albumin (OR = 2.06), low BMI (OR = 1.75), and low hemoglobin (OR = 1.34). CONCLUSION:Free flap compromise remains a clinically significant complication. These findings support integrating modifiable physiological markers into preoperative risk stratification and implementing targeted, multidisciplinary optimization strategies to improve flap outcomes.

Background:Patients with head and neck cancer (HNC) frequently experience functional impairments and psychological distress following surgery or radiotherapy. While mobile health (mHealth) interventions are increasingly integrated into clinical care to support patient self-management and home-based recovery, evidence of their effectiveness in HNC remains inconsistent. Objective:This study aims to evaluate the effectiveness of mHealth interventions on quality of life (QoL), psychological symptoms, physical symptoms, and functional recovery among HNC survivors. Methods:This systematic review and meta-analysis followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Overall, 12 electronic databases were searched for randomized controlled trials published up to December 1, 2025. Two reviewers independently performed study selection, data extraction, and risk of bias assessment using the Cochrane Risk of Bias 2.0 tool. Certainty of evidence was evaluated using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach. Pooled effects were calculated as standardized mean differences (SMDs) with 95% CIs. The primary outcome was QoL; secondary outcomes included anxiety, depression, fatigue, pain, swallowing function, and maximal interincisal opening (MIO). Results:A total of 26 randomized controlled trials involving 2385 participants were included. mHealth interventions significantly improved QoL (SMD 0.64, 95% CI 0.41-0.88; P<.001), anxiety (SMD -0.75, 95% CI -1.42 to -0.08; P=.03), depression (SMD -0.89, 95% CI -1.37 to -0.40; P<.001), and fatigue (SMD -0.85, 95% CI -1.19 to -0.51; P<.001). Pain showed a small reduction (SMD -0.37, 95% CI -0.49 to -0.24; P<.001). However, the improvement in swallowing function reached only borderline significance (SMD 0.66, 95% CI 0.28-1.04; P=.04), suggesting that current evidence for this outcome is fragile. No significant effect was found for MIO (P=.68). Subgroup analysis revealed that interventions featuring home practice support, self-monitoring, and shorter durations (<3 months) yielded stronger clinical effects. The overall certainty of evidence ranged from low to very low. Conclusions:mHealth interventions effectively enhance QoL and alleviate psychosocial distress in patients. However, evidence for improving swallowing function and MIO remains insufficient. Future research should prioritize standardized protocols and high-quality trials to validate long-term clinical value.

BACKGROUND:This study aimed to evaluate and rank the efficacy of common preprocedural mouthwashes in reducing microbial aerosols during dental procedures via network meta-analysis (NMA) and provide evidence-based guidance for clinical infection control. METHODS:We systematically searched eight electronic databases from inception to February 2025. Randomized controlled trials (RCTs) assessing mouthwashes for reducing microbial aerosols during dental procedures were included. A Bayesian NMA with a random-effects model was performed. Risk of bias was assessed using the Cochrane tool, and the certainty of evidence was evaluated using the CINeMA framework. Surface under the cumulative ranking curve (SUCRA) and standardized mean difference (SMD) with 95% confidence interval (CI) were calculated to quantify intervention effects. RESULTS:Twenty-five RCTs involving 1111 participants and eight interventions were included. Compared with the control group, chlorhexidine (CHX) showed the largest effect (SMD = -7.10, 95% CI [-9.44, -4.73]), followed by herbal mouthwash (SMD = -5.16, 95% CI [-8.04, -2.17]) and povidone-iodine (PVP-I) (SMD = -4.57, 95% CI [-8.79, -0.21]). Efficacy ranking based on SUCRA values was as follows: CHX (0.90), cetylpyridinium chloride (CPC) (0.68), herbal mouthwash (0.61), PVP-I (0.53), essential oil mouthwash (0.44), normal saline (0.42), hydrogen peroxide (0.39), and control (0.03). CONCLUSIONS:CHX appears to be the most effective mouthwash for reducing microbial aerosols, with CPC and herbal mouthwashes as viable alternatives, particularly for patients with CHX intolerance or mucosal sensitivity. However, evidence for CPC is limited, and the overall certainty is low. Further well-designed RCTs are needed, especially to evaluate efficacy against viral aerosols.

Introduction and aims While the association between body mass index (BMI) and dental caries in adults is debated, prior meta-analyses have primarily focused on caries prevalence using dichotomous outcomes. This study offers a novel approach by aiming to quantitatively synthesize the relationship between BMI and the burden of dental caries, using continuous data from the mean DMFT (decayed, missing, and filled teeth) and DT (decayed teeth) indices in adults. Methods PubMed, Embase, CINAHL, and Web of Science were searched through March 2025 for observational studies comparing DMFT/DT scores across BMI categories in adults. Methodological quality was assessed using the AHRQ checklist. Data were pooled using random-effects models, with subgroup analyses conducted to explore heterogeneity. Evidence certainty was evaluated using the GRADE framework. Results Twelve cross-sectional studies (n = 85,975) were included. Obese adults had higher DMFT scores than normal-weight individuals (WMD: 1.75, 95% CI: 0.05-3.46), though statistical significance was lost in sensitivity analysis. A more robust association was found for the combined overweight/obese group (WMD: 1.28, 95% CI: 0.17-2.39). For DT, significant associations emerged only in high-income countries for overweight (WMD: 0.60, 95% CI: 0.39-0.81) and combined overweight/obese categories (WMD: 0.59, 95% CI: 0.40-0.78). No significant associations were identified for underweight individuals. Conclusions Our findings provide quantitative evidence for associations between excess body weight and cumulative dental caries burden in adults. The observed heterogeneity and low evidence certainty, particularly the influence of national income levels, highlight the complexity of this association and underscore the need for cautious interpretation. Clinical Relevance Findings support considering oral health in obesity management. Clinicians should recognize that excess body weight may indicate not just a higher risk of having caries, but a greater severity of the disease burden.

OBJECTIVE:To evaluate the effects of a Health Belief Model-based oral health management program on self-efficacy, oral health behaviors, and three periodontal clinical indicators among pregnant women. STUDY DESIGN:A randomized controlled trial was conducted with 65 participants randomly allocated to the intervention (n = 39) and control (n = 26) groups. The intervention included one face-to-face education, three video calls, two online lectures, and regular follow-up supervision in 1 month, while the control group received one face-to-face education. Self-efficacy for oral self-care, three periodontal clinical indicators, and oral health behaviors were measured at baseline (T0), post-intervention (T1), and 2-month follow-up (T2). RESULTS:The total and three domains' scores on the Self-efficacy Scale for Self-care in the intervention group increased appreciably (p < 0.001). Oral health behaviors among the intervention group exhibited more remarkable improvement than the control group did at the two post-baseline times (all p < 0.05). The intervention group showed significantly higher scores in gingival index (p = 0.021) and plaque index (p = 0.001) than the control group at T1, while only plaque index scores were significantly different between the two groups at T2 (p < 0.001). CONCLUSION:The findings demonstrated an effective educational strategy to promote self-efficacy, oral health behaviors, and oral health status in pregnant women.

ABSTRACT Background Surgical site infections represent one of the most common and costly hospital‐acquired infections. As a potential preventive measure for surgical site infections, the specific effectiveness of perioperative oral management remains unclear. Methods We conducted systematic searches, study selection, data extraction, and meta‐analysis. Subgroup analysis was performed based on patient disease type, surgical site, intervention type, and intervention frequency to assess the effects of perioperative oral management under different conditions. Additionally, the certainty of evidence for critical outcomes was evaluated through the GRADE framework. Results Sixteen studies were finally included, comprising 10 052 patients. Both experimental studies (RR = 0.64; 95% CI, 0.48–0.85; p = 0.002) and observational studies (OR = 0.49; 95% CI, 0.37–0.65; p < 0.001) indicate that perioperative oral management significantly reduced the risk of surgical site infections. Subgroup analyses revealed a more modest effect of perioperative oral management (POM) in patients with cardiovascular disease (OR = 0.72; 95% CI, 0.54–0.96; p = 0.027) and non‐oncology patients (OR = 0.66; 95% CI, 0.48–0.92; p = 0.013). It is crucial to note that POM protocols excluding both oral chemical and mechanical cleaning components showed no significant effect (OR = 0.76; 95% CI, 0.44–1.31; p = 0.323). Additionally, perioperative oral management was associated with a reduction in hospital length of stay (MD = −1.88; 95% CI, −2.98 to −0.78; p = 0.001). Conclusion Perioperative oral management significantly reduces surgical site infections and shortens hospital stays. In clinical practice, patient‐specific oral management plans should be developed to enhance perioperative infection control. Future studies are needed to explore the best practices and scope of application of preoperative oral management.

Background Needlestick injuries (NSIs) are recognised as a major occupational health concern for health care workers, particularly dental assistants who fre- quently handle sharp instruments. However, little attention has been paid to this vulnerable group. Therefore, it is important to evaluate the prevalence of NSIs among dental assistants and identify associated risk factors to promote the safety level of dental assistants and the development of prevention strategies. Methods We followed PRISMA guidelines and registered the protocol with PROSPERO (CRD 42023404766), searching PubMed, Web of Science, Embase, Scopus, and Ovid databases for studies published between January 2000 and January 2023. We selected relevant studies by screening titles and abstracts, and then evaluated the full texts. Risk of bias was assessed using the Critical Appraisal Checklist for prevalence studies proposed by the Joanna Briggs In- stitute (JBI). Results Eleven studies involving 2663 dental assistants were included. The pooled NSIs prevalence was 44% (95% confidence interval (CI) = 0.29-0.59), with significant heterogeneity (I2 = 98.5%). High-risk procedures were cleaning in- strument and handling syringes. Subgroup analysis indicated a declining NSI prevalence trend (53 to 34%). In terms of the degree of national development, NSI prevalence was higher in developed countries (47%) than in developing countries (36%). Conclusions The 44% prevalence of NSIs among dental assistants implies non-negligible risk. Instrument cleaning and the handling of local anaesthet- ic syringes are the principal procedures and associated factors contributing to their NSI exposure.

Introduction:Adherence to supportive periodontal care (SPC) is essential for preventing disease recurrence and maintaining oral health. Psychological and emotional support from family members may play a vital role in sustaining long-term adherence, yet the influence of family function on SPC adherence and outcomes remains underexplored. Objective:To evaluate the impact of family function on adherence to SPC and its subsequent effect on periodontal prognosis. Methods:This retrospective study included 400 patients aged 20-73 years who received active periodontal therapy between January 2018 and January 2020 and entered SPC for at least one year. Family functioning was assessed using the Apgar score. Patient adherence was evaluated based on adherence to scheduled follow-up visits within a 3-month period. Clinical parameters, including probing depth and bleeding on probing, were recorded at baseline and follow-up visits. Multivariable logistic regression was used to assess the relationship between family functioning, patient adherence, and treatment outcomes. Results:The regular adherence group had an adherence rate of 38%, and their family care index was significantly higher than that of the irregular group (9.58 ± 0.58 vs. 9.00 ± 0.90, p < .01). Both groups showed improvements in periodontal prognosis following SPC (p < .01). Patients with a higher family care index exhibited better adherence, with a more pronounced improvement in prognosis (p < .01). Logistic regression analysis identified gender (odds ratio [OR] = 2.730, 95% CI [1.683, 4.430], p < .01), age (OR = 0.999, 95% CI [0.970, 1.02], p < .01), and orthodontic history (OR = 7.941, 95% CI [1.497, 42.116], p < .05) as significant factors influencing SPC adherence. Conclusion:Patients with higher family function scores demonstrate better adherence with SPC, resulting in more favorable treatment outcomes. The involvement of family members plays a critical role in enhancing patient adherence to treatment protocols, thereby improving both oral health and overall quality of life.

Introduction and Aims: This study aimed to determine needlestick and sharps injuries (NSIs) incidence, identify associated risk factors, and describe reporting practices among dental instrument reprocessing personnel (DIRP) in China. Methods: A nationwide cross-sectional study utilized stratified multistage random sampling across seven Chinese regions. Validated questionnaires were administered to 1942 DIRP from 130 dental facilities, collecting data on demographics, occupational conditions, NSI history, and reporting. Multivariate logistic regression identified independent NSI predictors. Results: The one-year NSI period incidence was 21.7% (n = 421/1942), with 28.5% of these individuals experiencing multiple injuries. Daily instrument handling volume demonstrated a dose-response relationship with NSI risk (aOR = 5.73, 95% CI: 3.17-10.34, for >1000 vs. ≤100 instruments). The NSI reporting rate was 87.2%. Primary barriers included demanding work schedules (51.9%) and perceived low exposure risk (40.7%). Post-training assessment was significantly associated with a reduced NSI risk (aOR = 0.65, 95% CI: 0.51-0.83). Both receiving NSI prevention training (aOR = 3.11) and undergoing post-training assessment (aOR = 2.47) significantly increased NSI reporting. Conclusion: NSI prevalence among Chinese DIRP is substantial, strongly associated with instrument workload and work experience, and influenced by training assessment. Targeted interventions focusing on workload management, assessed training, and streamlined reporting are essential. Clinical Relevance: These findings highlight critical areas for improving DIRP safety. Implementing evidence-based workload limits, ensuring training includes competency assessment, and simplifying NSI reporting can reduce preventable injuries and enhance occupational health in dental settings globally.

Although the discussion about oral mucositis in Head and Neck Cancer (HNC) patients has become a prominent issue, its incidence and influencing factors have not been thoroughly synthesized. This meta-analysis aims to integrate the prevalence and associated factors of radiation-induced oral mucositis among HNC patients. This study searched the following electronic databases: PubMed, the Cochrane Database, the Web of Science, EMBASE, CNKI, the Wanfang Database, and the VIP Database. The publication timeframe for the included studies ranged from January 2005 until January 2024. Two investigators used the NOS scale and AHRQ evaluation criteria for quality evaluation. All qualified studies and statistical analyses were conducted using RevMan 5.2 and Stata 17.0. Thirty eligible studies were included in the analysis. The results show that the prevalence of radiation-induced oral mucositis in HNC patients was 94

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.

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. 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.

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: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.
