ABSTRACT
Dental general anaesthesia provides a comfortable treatment modality for children with early childhood caries and children's dental anxiety, but US Food and Drug Administration safety warnings have raised concerns about the neurotoxicity of general anaesthetic drugs. Currently, anaesthetic drugs have been found to impair neurocognitive function in animals, with possible mechanisms including cell damage, cell loss and impaired neuronal network function. The outcomes of clinical studies on the neurocognitive effects of surgical general anaesthesia in children have been inconsistent. However, studies focusing on dental general anaesthesia in children suggest that it does not affect neurocognitive function. In general, a growing number of studies suggest that dental general anaesthesia does not affect neurocognitive development in children. Moreover, dental general anesthesia should be used as normal when other behavioural management is unavailable.

Background: For children who are unable to cooperate due to severe dental anxiety (DA), dental treatment of childhood caries under Dental General Anesthesia (DGA) is a safe and high-quality treatment method. This study aims to evaluate the impact on neurocognitive functions and the growth and development of children 2 years after dental procedure based on previous research, and further establish a causal relationship between general anesthesia (GA) and changes in children's neurocognitive functions by incorporating Mendelian Randomization (MR) analysis. Methods: Data were collected and analyzed from 340 cases of S-ECC procedures of preschool children conducted in 2019. This involved comparing the neurocognitive outcomes 2 years post-operation of preschool children receiving dental procedures under general anesthesia or local anesthesia. Physical development indicators such as height, weight, and body mass index (BMI) of children were also compared at baseline, half a year post-operation, and 2 years post-operation. We performed a Mendelian randomization analysis on the causal relationship between children's cognitive development and general anesthesia, drawing on a large-scale meta-analysis of GWAS for anesthesia, including multiple general anesthesia datasets. Results: Outcome data were obtained for 111 children in the general anesthesia group and 121 children in the local anesthesia group. The mean FSIQ score for the general anesthesia group was 106.77 (SD 6.96), while the mean score for the local anesthesia group was 106.36 (SD 5.88). FSIQ scores were equivalent between the two groups. The incidence of malnutrition in children in the general anesthesia group was 27.93% (p < 0.001) before surgery and decreased to 15.32% (p > 0.05) after 2 years, which was not different from the general population. The IVW method suggested that the causal estimate (p = 0.99 > 0.05, OR = 1.04, 95% CI = 5.98 × 10-4-1.82 × 103) was not statistically significant for disease prevalence. This indicates no genetic cause-and-effect relationship between anesthesia and childhood intelligence. Conclusion: There were no adverse outcomes in neurocognitive development in 2 years after severe early childhood caries (S-ECC) procedure under total sevoflurane-inhalation in preschool children. The malnutrition condition in children can be improved after S-ECC procedure under general anesthesia. Limited MR evidence does not support a correlation between genetic susceptibility to anesthesia and an increased risk for intelligence in children.
ABSTRACT
Sedation is a depression of a patient's state of consciousness, induced by medications, that can reach different levels of intensity during a medical procedure. Conscious sedation produces a minimally depressed level of consciousness without impairment of the ability to maintain an open airway, of protective reflexes or of responses to verbal and physical stimulation. This umbrella review is aimed at critically assessing the available systematic reviews (SRs) and meta-analyses (MA) on sedation in children/adolescents. An electronic database search was conducted that included Pubmed-Medline, Web of Science, Cochrane, Scopus, Scielo, Embase, LILACS and TRIP and the scope of which extended until January 2023. The risk of bias (RoB) of SRs was analyzed using the Measurement Tool to Assess SRs criteria 2 (AMSTAR2). Of 998 entries, 37 SRs were included. In terms of methodological quality, eight studies were assessed as having critically low quality, four studies had low quality, nine studies had moderate quality, and sixteen were considered to be of high quality. Based on the current guidelines, the most employed drugs in pediatric dentistry for sedation are nitrous oxide and midazolam; however, the available evidence supporting their use is insufficient and of low/critically low quality. The combined technique is recommended (nitrous oxide (30-50%) + midazolam). The optimal dose of oral midazolam is 0.75 mg/kg. The level of methodological quality of SRs is expected to increase according to the results and future directions of this umbrella review.
ABSTRACT
Antibiotic prophylaxis prior to dental work in bicuspid aortic valve (BAV) patients is currently a matter of debate. The American Dental Association does not require those with native BAV to receive antibiotic prophylaxis prior to dental work as BAV is considered an "intermediate" risk for infective endocarditis (IE). We present the case of a 63-year-old male, with a medical history of BAV, who acquired Streptococcus sanguinis IE after a routine dental cleaning four months prior to initial onset of symptoms. He exhibited new-onset and severe aortic regurgitation at presentation, requiring urgent aortic valve replacement to restore valve function. BAV patients are at high risk of IE, emphasizing the need for prophylactic antibiotics in dental cleaning as well as invasive dental procedures in those with BAV.
ABSTRACT
BACKGROUND: Postgraduate pediatric dental residents' competency, to perform dental rehabilitation procedures under General anesthesia (GA), at different levels of training is challenging for operation time control. An adequate operation time (OT) for children decreases morbidity risk and improves hospital time utilization efficiency. The aim of the study is to assess the effect of pediatric dental resident training level on OT for pediatric dental rehabilitation procedures under GA at King Abdulaziz Medical City (KAMC). METHODS: A cross-sectional study included pediatric dental rehabilitation performed under GA by pediatric dental residents at (KAMC) -Jeddah from October/2015 to September/2022. The primary outcome was OT, and the predictive variable was resident training levels. A linear regression analysis was used to compare OT between procedures performed by junior (years 1-2) or senior (years 3-4) trainees, adjusting for patient and operative factors. RESULTS: One thousand seven pediatric dental rehabilitation cases were performed under GA by junior (13) and senior (31) residents. The univariant analysis indicated that OT for senior residents was significantly longer (13 min) than for junior residents. However, the linear regression analysis showed that senior residents had a significantly shorter OT when considering the more dental procedures performed per case under GA than junior residents. Senior residents took significantly more radiographs and performed more primary pulp therapies and multi-surface anterior colored restorations under GA than junior residents. CONCLUSIONS: The OT for pediatric dental rehabilitation procedures under GA is associated with resident training level. The total OT was significantly longer based on procedure number, type, and resident level. The study indicated that senior residents could manage more complex cases in a shorter time. The finding emphasizes the importance of assigning GA cases to residents based on their level and the case's complexity. Additionally, it helps standardize the resident privileges under GA and understand the impact of residency training on hospital efficiency.

Introduction: The research on mood states in dental consultation has focused mainly on pediatric ages; however, it is important to know what happens in other age groups. Objective: To evaluate the mood of older adults prior to a first-level dental procedure at the Zaragoza University Health Care Clinic. Materials and methods: An exploratory, observational, cross-sectional study was carried out with a sample of 34 older adults (22 women and 12 men) with an average age of 69.2. The sample selection was non-probabilistic for convenience. The Mood Assessment Scale was used, which is a self-report instrument, validated in the adult population, for clinical and non-clinical conditions. Results: A high score was found in the joy subscale with a mean of 6.63 and a standard deviation of 2.7. For the mood subscales considered negative such as Anxiety, a mean of 3.5 and a standard deviation of 2.5 was obtained. For Sadness -Depression, a mean of 3.1 and a standard deviation of 3.0 were obtained; and finally for the Anger-Hostility subscale, a mean of 2.7 and a standard deviation of 3.1 were obtained. Conclusion: Low levels were found in negative mood states for the subscales of Anxiety, Sadness-Depression and Anger-Hostility. Meanwhile, in positive mood states there is a high level, both in item and in the subscale of Joy.
ABSTRACT
BACKGROUND: Dental treatments often cause anxiety, fear, and stress in patients. Intravenous sedation is widely used to alleviate these concerns, and various agents are employed for sedation. However, it is important to find safer and more effective sedation agents, considering the adverse effects associated with current agents. This study aimed to investigate the efficacy and safety of remimazolam besilate (hereinafter called "remimazolam") and to determine the optimal dosages for sedation in outpatients undergoing dental procedures. METHODS: Thirty-one outpatients aged 18-65 years scheduled for impacted third molar extraction were included in the study. Remimazolam was administered as a single dose of 0.05 mg/kg followed by a continuous infusion at a rate of 0.35 mg/kg/h, with the infusion rate adjusted to maintain a sedation level at a Modified Observer's Assessment of Alertness/Sedation (MOAA/S) score of 2-4. The primary endpoint was the sedation success rate with remimazolam monotherapy, and the secondary endpoints included induction time, recovery time, time until discharge, remimazolam dose, respiratory and circulatory dynamics, and frequency of adverse events. RESULTS: The sedation success rate with remimazolam monotherapy was 100%. The remimazolam induction dose was 0.08 (0.07-0.09) mg/kg, and the anesthesia induction time was 3.2 (2.6-3.9) min. The mean infusion rate of remimazolam during the procedure was 0.40 (0.38-0.42) mg/kg/h. The time from the end of remimazolam administration to awakening was 8.0 (6.7-9.3) min, and the time from the end of remimazolam administration to discharge was 14.0 (12.5-15.5) min. There were no significant respiratory or circulatory effects requiring intervention during sedation. CONCLUSIONS: Continuous intravenous administration of remimazolam can achieve optimal sedation levels without significantly affecting respiratory or circulatory dynamics. The study also provided guidance on the appropriate dosage of remimazolam for achieving moderate sedation during dental procedures. Additionally, the study findings suggest that electroencephalogram monitoring can be a reliable indicator of the level of sedation during dental procedural sedation with remimazolam. TRIAL REGISTRATION: The study was registered in the Japan Registry of Clinical Trials (No. jRCTs061220052) on 30/08/2022.

BACKGROUND: Although the risk of dental procedures as a cause of bacteremia has been recognized, evidence regarding the association between dental procedures and late periprosthetic joint infection (LPJI) is scarce. We sought to determine whether dental procedures are associated with an increased risk of LPJI. METHODS: The study was conducted under a case-crossover design using a large claims database in Japan. We identified adult patients who had undergone dental procedures and were hospitalized for LPJI between April 2014 and September 2021. Exposure to dental procedures was assessed during a case period of 1-4 weeks, with two control periods of 9-12 weeks and 17-20 weeks, preceding LPJI hospital admission. Conditional logistic regression models were used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) of LPJI associated with dental procedures in the case period compared with the two control periods. RESULTS: In total, 241 patients with LPJI were included in the case-crossover study. At least one dental procedure was performed in 46 patients (19.1%) in the hazard period and in 75 patients (31.1%) in the control periods. The OR for LPJI with dental procedures was 0.96 (95% CI, 0.61-1.53; p = 0.88). Findings were robust in several sensitivity analyses, including stratification by whether the dental procedure included antibiotic prophylaxis. CONCLUSIONS: This study suggests that dental procedures are not associated with increased risk of LPJI, and will raise questions about the recommendation for antibiotic prophylaxis before dental procedures.
ABSTRACT
The cellular metabolic processes ensure the physiological integrity of the dentine-pulp complex. Odontoblasts and odontoblast-like cells are responsible for the defence mechanisms in the form of tertiary dentine formation. In turn, the main defence reaction of the pulp is the development of inflammation, during which the metabolic and signalling pathways of the cells are significantly altered. The selected dental procedures, such as orthodontic treatment, resin infiltration, resin restorations or dental bleaching, can impact the cellular metabolism in the dental pulp. Among systemic metabolic diseases, diabetes mellitus causes the most consequences for the cellular metabolism of the dentine-pulp complex. Similarly, ageing processes present a proven effect on the metabolic functioning of the odontoblasts and the pulp cells. In the literature, several potential metabolic mediators demonstrating anti-inflammatory properties on inflamed dental pulp are mentioned. Moreover, the pulp stem cells exhibit the regenerative potential essential for maintaining the function of the dentine-pulp complex.
ABSTRACT
Air embolism is a rare and life-threatening event that occurs when air enters the cardiovascular system, usually secondary to iatrogenic vascular procedures. We present a 58-year-old woman who underwent a dental procedure (devitalization of a tooth) under local anesthesia, with a sudden onset of coma during manipulation and documentation of air in the vessels of the right frontal convexity sulci. After cerebral air embolism was confirmed, she received hyperbaric oxygen therapy, with resorption of the gas, but clinically she developed a super-refractory status epilepticus with a persistent coma. The slow clinical course required the exclusion of other etiologies of coma. The pathophysiology is not well known; however, it appears to be related to the injection of air by the high-speed dental drill through the soft tissue adjacent to the roots of the teeth, nearby the bloodstream. We highlight this event because of this unlikely association, which may delay diagnosis and the good results of hyperbaric medicine on prognosis.
ABSTRACT
The risk of microbial air contamination in a dental setting, especially during aerosol-generating dental procedures (AGDPs), has long been recognized, becoming even more relevant during the COVID-19 pandemic. However, individual pathogens were rarely studied, and microbial loads were measured heterogeneously, often using low-sensitivity methods. Therefore, the present study aimed to assess microbial air contamination in the dental environment, identify the microorganisms involved, and determine their count by active air sampling at the beginning (T0), during (T1), and at the end (T2) of ultrasonic scaling in systemically and periodontally healthy subjects. Air microbial contamination was detected at T0 in all samples, regardless of whether the sample was collected from patients treated first or later; predominantly Gram-positive bacteria, including Staphylococcus and Bacillus spp. and a minority of fungi, were identified. The number of bacterial colonies at T1 was higher, although the species found were similar to that found during the T0 sampling, whereby Gram-positive bacteria, mainly Streptococcus spp., were identified. Air samples collected at T2 showed a decrease in bacterial load compared to the previous sampling. Further research should investigate the levels and patterns of the microbial contamination of air, people, and the environment in dental settings via ultrasonic scaling and other AGDPs and identify the microorganisms involved to perform the procedure- and patient-related risk assessment and provide appropriate recommendations for aerosol infection control.

Abstract Introduction: Dental procedures have been associated with bacteriemia and infective endocarditis. Objective: To determine the prevalence of infective endocarditis from dental procedures. Materials and methods: A descriptive, retrospective quantitative study was carried out. Records of infective endocarditis of which the general identification, sex, age, socioeconomic status, dental procedure report, type of dental procedure and non-specified infective endocarditis information was collected. Additionally, information was recorded on the type of medical/surgical procedure or medical condition that was associated. Categorical variables are presented as absolute and relative frequencies. The data were compiled in a spreadsheet for processing in statistical software (SPSS ver. 25). Results: Of the 154 cases of infective endocarditis registered, only 1 case (0.7%) reported an endodontic-type dental procedure prior to hospitalization. The most reported related cause was catheterization for hemodialysis (37%) followed by unspecified bacteriemia (22%) and cardiovascular condition associated with heart valves and pacemakers (18.8%). In 15.6% of the cases, it was reported as non-specific infective endocarditis. The most isolated microorganisms belonged to the genus Staphylococcus followed by Streptococcus. Conclusions: The frequency of bacterial endocarditis related to dental procedures was less than 1%. Medical-surgical procedures remain the most common cause of bacterial endocarditis.

Empyema is often caused by Streptococcus anginous species, followed by Streptococcus pneumoniae. The organism Streptococcus gordonii belongs to the Streptococcus mitis group, which rarely causes empyema. We report the case of a 59-year-old man who presented with exertional dyspnea and chest pain on the right side. The image obtained showed effusion on the right side. Streptococcus gordonii was recovered from purulent pleural effusion culture. The patient underwent video-assisted thoracoscopic surgery with decortication, pneumolysis and received antibiotics for 13 days. A total of seven cases were analyzed after combining six cases in the literature and our presented case. The majority of Streptococcus gordonii empyema patients were male (six patients, 86%) and empyema on the right side (five patients, 71%). Common risk factors included poor dental hygiene or recent dental procedure (three patients, 43%), diabetes mellitus (three patients, 43%), and smoking (three patients, 43%). Only a few cases developed empyema-related complications, including bacteremia (one patient, 14%) and spleen abscesses (one patient, 14%). Most patients underwent chest tube insertion (seven patients, 100%) and survived without recurrent empyema (six patients, 86%).
ABSTRACT
PURPOSE: Infective endocarditis (IE) is a severe bacterial infection. As a measure of prevention, the administration of antibiotic prophylaxis (AP) prior to dental procedures was recommended in the past. However, between 2007 and 2009, guidelines for IE prophylaxis changed all around the word, limiting or supporting the complete cessation of AP. It remains unclear whether AP is effective or not against IE. METHODS: We conducted a systematic review whether the administration of AP in adults before any dental procedure, compared to the non-administration of such drugs, has an effect on the risk of developing IE. We searched for studies in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via OVID, and EMBASE. Two different authors filtered articles independently and data extraction was performed based on a pre-defined protocol. RESULTS: The only cohort study meeting our criteria included patients at high-risk of IE. Analysis of the extracted data showed a non-significant decrease in the risk of IE when high-risk patients take AP prior to invasive dental procedures (RR 0.39, p-value 0.11). We did not find other studies including patients at low or moderate risk of IE. Qualitative evaluation of the excluded articles reveals diversity of results and suggests that most of the state-of-the-art articles are underpowered. CONCLUSIONS: Evidence to support or discourage the use of AP prior to dental procedures as a prevention for IE is very low. New high-quality studies are needed, even though such studies would require big settings and might not be immediately feasible.

Various infective complications can be seen after a dental procedure. They are rarely resistant to standard therapy. In the case we present, a case of preseptal cellulitis caused by pseudomonas oryzihabitans after tooth extraction in a male patient who did not have any underlying cause. As in our case, evaluation of the cases resistant to standard treatment in terms of drainage and multidisciplinary management of culture results together with infectious diseases will increase the treatment success rate.

In recent years, the dental treatment of children under sedation and/or general anesthesia on an outpatient basis has been developed as a behavioral management model in pediatric dentistry. The objective of this study was to establish the percentage of pediatric patients who required deep sedation on an outpatient basis in dental offices in the city of Cuenca, Ecuador. An observational study was conducted with a sample of 450 records of school- and preschool-age patients, where the variables were type and time of treatment, age, and sex. Statistical data were analyzed using the statistical program SPSS V.27 (IBM, Armonk, NY, USA). The highest percentage of children who received sedation were of preschool age. In general, there were three types of procedures per session, the most frequent being restorations (67%), followed by pulp treatment (49.8%) and, less frequently, minor surgery. The need for sedation for dental procedures is high in preschool patients, and ambulatory sedation has contributed to meeting this need. However, a regulation for its use is required at a national level.
ABSTRACT
Ingestion and aspiration can be accidental or intentional events in both adults and children. Approximately 1500 people in the United States die from ingestion of foreign bodies annually. Patients with cognitive disabilities, neurological disorders, elderly age or incarcerated patients carry the highest risk of intentional and/or accidental ingestion of foreign objects. Although uncommon, ingestion of foreign objects during dental procedures can be potentially life-threatening and increased awareness is important. Sharp objects ingested from dental procedures can cause impaction, obstruction, hemorrhage, or perforation and may need endoscopic or surgical intervention. Herein we report a case of a 22-year-old male, who underwent routine dental cleaning and accidentally ingested an endodontic file, retrieved from the ascending colon endoscopically without complications.
ABSTRACT
Various dental, maxillofacial, and orthopedic surgical procedures (DMOSP) have been known to produce bioaerosols, that can lead to the transmission of various infectious diseases. Hence, a systematic review (SR) aimed at generating evidence of aerosols generating DMOSP that can result in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), further investigating their infectivity and assessing the role of enhanced personal protective equipment (PPE) an essential to preventing the spreading of SARS-CoV-2 during aerosol-generating procedures (AGPs). This SR was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA) guidelines based on a well-designed Population, Intervention, Comparison, Outcomes and Study (PICOS) framework, and various databases were searched to retrieve the studies which assessed potential aerosolization during DMOSP. This SR included 80 studies (59 dental and 21 orthopedic) with 7 SR, 47 humans, 5 cadaveric, 16 experimental, and 5 animal studies that confirmed the generation of small-sized < 5 µm particles in DMOSP. One study confirmed that HIV could be transmitted by aerosolized blood generated by an electric saw and bur. There is sufficient evidence that DMOSP generates an ample amount of bioaerosols, but the infectivity of these bioaerosols to transmit diseases like SARS-CoV-2 generates very weak evidence but still, this should be considered. Confirmation through isolation and culture of viable virus in the clinical environment should be pursued. An evidence provided by the current review was gathered by extrapolation from available experimental and empirical evidence not based on SARS-CoV-2. The results of the present review, therefore, should be interpreted with great caution.
ABSTRACT
AIMS: The incidence of infective endocarditis related to cardiac implantable electronic devices (CIEDs) has gradually increased. The risk associated with dental procedures in patients with CIED implantation and the need for prevention of infective endocarditis remain unclear. The present study investigated the incidence and risk of infective endocarditis associated with invasive dental procedures in patients with CIEDs. METHODS AND RESULTS: We analysed a nationwide population-based cohort of patients with CIEDs who underwent dental procedures. We performed a self-controlled case series analysis and evaluated the incidence rate ratio of infective endocarditis 3 months after dental procedures. Of a total of 62 019 patients who underwent CIED implantation, 32 536 patients underwent at least one dental procedure during follow-up, and the mean number of dental procedures was 3.4 per patient. They were 152 infections with an incidence of 445 per 100 000 person-years in the dental procedure period and 500 events at an incidence of 255 per 100 000 person-years in the non-dental procedure period. The CIED-related infective endocarditis in the dental procedure period occurred significantly more frequently than during non-dental procedure periods (odds ratio, 1.75; 95% confidence interval, 1.48-2.05; P < 0.001). The mean time interval from dental procedure to infective endocarditis was 59.6 ± 47.3 days. CONCLUSION: Invasive dental procedures are associated with an increased risk of infective endocarditis in those who underwent CIED implantation. Appropriate preventive therapy might be needed in these patients.

Background/purpose: The epidemiology of infective endocarditis (IE) is under constant change due to the aging society and increases in antimicrobial-resistant pathogens. However, IE remains severe. This study aimed to review the current clinical characteristics of IE and the antimicrobial susceptibility of oral bacteria (OB) isolated from blood cultures to implement appropriate antimicrobial prophylaxis. Materials and methods: We retrospectively investigated the clinical features of 180 patients with IE in whom OB and pathogens except OB (eOB) were identified as causative microorganisms via blood cultures. The susceptibility of the OB group to eight antibiotics was examined by broth microdilution. Results: Among causative microorganisms, the isolation rate of staphylococci was slightly higher than that of OB; however, the difference was not significant (36.7% vs. 33.8%, p = 0.3203). The number of patients with underlying cardiac disease was significantly higher in the OB group than in the eOB group (53.7% vs. 34.1%, p = 0.0113). Only one ampicillin-resistant OB was detected (2.0%). OBs were significantly less susceptible to clarithromycin and azithromycin than to ampicillin (98.0% vs. 66.7% and 98.0% vs. 60.0%, p = 0.0003 and p = 0.0003, respectively). Moreover, OBs were significantly less susceptible to clarithromycin and azithromycin than to clindamycin (66.7% vs. 88.2% and 60.0% vs. 88.2%, p = 0.0301 and p = 0.0217, respectively). Conclusion: OBs were susceptible to ampicillin. However, the susceptibility of OBs to clarithromycin and azithromycin was significantly lower than that to ampicillin and clindamycin. These results are important and should help decisions regarding guide antimicrobial prophylaxis.
