RESUMO
OBJECTIVE: To evaluate the efficacy of microchips and 3D microsensors in the measurement of orthodontic forces. METHODS: Through September 2023, comprehensive searches were conducted on PubMed/MEDLINE, SCOPUS and SCIELO without restrictions. RESULTS: After removing duplicate entries and applying the eligibility criteria, 23 studies were included for analysis. All the studies were conducted in vitro, and slightly more than half of them were centred on evaluating orthodontic forces exerted by aligners. Eight utilized microchips as measurement tools, while the remaining studies made use of 3D microsensors for their assessments. In the context of fixed appliances, key findings included a high level of agreement in 3-dimensional orthodontic force detection between simulation results and actual applied forces. Incorporating critical force-moment combinations during smart bracket calibration reduced measurement errors for most components. Translational tooth movement revealed a moment-to-force ratio, aligning with the bracket's centre of resistance. The primary findings in relation to aligners revealed several significant factors affecting the forces exerted by them. Notably, the foil thickness and staging were found to have a considerable impact on these forces, with optimal force transmission occurring at a layer height of 150 µm. Furthermore, the type of material used in 3D-printing aligners influenced the force levels, with attachments proving effective in generating extrusive forces. Deliberate adjustments in aligner thickness were observed to alter the forces and moments generated. CONCLUSIONS: Microchips and 3D sensors provide precise and quantitative measurements of orthodontic forces in in vitro studies, enabling accurate monitoring and control of tooth movement.
RESUMO
OBJECTIVE: This study aims to utilize the finite element method (FEM) to compare the dentoalveolar and mandibular effects associated with anterior mandibular repositioning using AdvanSync® (ADV) and Twin Block (TB). METHODS: A patient with Class II skeletal malocclusion and mandibular retrognathism was selected. A TB appliance was subsequently applied. Computed Tomography (CT) scans were acquired at the beginning of treatment (T1) and 8 months later (T2). Concurrently, a numerical TB model was validated through FEM simulations, which were compared with the T2 results. The ADV appliance was virtually simulated to evaluate stress and deformation on the condyle, symphysis, first lower molar and lower central incisors. RESULTS: Both simulations demonstrated significant mandibular advancement. However, ADV led to less incisor proclination and more molar intrusion compared to TB. ADV exhibited increased stress in the lower molar area, while TB had higher stress in the lower incisor region. Stress and deformations in the condyle and mandibular symphysis were similar in both simulations, with the highest stress observed at the condylar neck and the lowest at the upper pole of the condylar head. CONCLUSIONS: Both appliances achieved similar levels of mandibular advancement, with greater proclination of the lower central incisors and more widespread distribution of stress and molar intrusion when using ADV compared to TB.
RESUMO
BACKGROUND: The noteworthy correlation between bite force and masticatory performance emphasizes its significance as a meaningful and objective method for assessing oral function. Furthermore, in the study of bruxism, the measurement of intraoral bite force assumes critical importance. Given the importance of assessing occlusal forces and bite force, this systematic review aims to assess the efficacy of wireless sensors in measuring these forces. METHODS: The search methodology employed in this systematic review adhered to the guidelines outlined by PRISMA. The strategy involved the exploration of various databases, including PubMed/MEDLINE, SCOPUS and SCIELO. An assessment tool was employed to evaluate the bias risk and study quality. RESULTS: This systematic review encompassed six prospective clinical studies involving a total of 89 participants. Wireless sensors for measuring occlusal forces and bite forces were predominantly employed in healthy adults or individuals with bruxism, along with children undergoing orthodontic treatment. All wireless sensors employed in the studies underwent validation and reproducibility assessments, affirming their reliability. The findings indicated that all wireless sensors exhibited efficacy in detecting occlusal forces and bite forces. CONCLUSION: Wireless sensors offer real-time monitoring of occlusal and bite forces, aiding in understanding force distribution and identifying bruxism patterns. Despite limited studies on their application, these sensors contribute to evolving insights. Integration into clinical practice requires careful consideration of factors like calibration and patient compliance. Ongoing research is crucial to address limitations and enhance the efficacy of wireless sensors in measuring occlusal and bite forces and managing bruxism.

OBJECTIVES: To describe the clinical features and location of oral lesions in patients with human monkeypox. METHODS: A systematic scoping review was accomplished by implementing the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews. The analysis incorporated varied databases and the gray literature. Keywords were implemented to search publications in all languages until July 2022. RESULTS: The initial electronic exploration included 889 reports, of which 843 studies were eliminated. Reading the full text occasioned the omission of 27 additional investigations. Finally, 19 publications were included. These reports analyzed 1256 patients with monkeypox, mostly described in Europe. Most of them were men who have sex with men. The study population consisted mainly of adults but children were also infected. The oral lesions of monkeypox patients were observed in different parts of the oral mucosa, including lips and tongue, but mainly in the tonsils (15 cases). The oral lesions manifested as papules, vesicles, pustules, and ulcers. Erythema, edema, enanthema, and severe pain were also observed, accompanied by tonsillar enlargement. Sore throat was also reported. Monkeypox is accompanied by a significant number of systemic manifestations, mainly including multiple skin lesions throughout the body, as well as lymphadenopathy, fever, headache, myalgia, and fatigue, among others. The symptoms associated with monkeypox were managed with different antiretroviral and antimicrobial therapies and medications to control pain and fever principally. Seventeen deaths were informed. CONCLUSION: Most monkeypox-associated oral lesions are seen in different parts of the oral mucosa, mainly in the tonsils manifested as papules, vesicles, pustules, and ulcers.

OBJECTIVES: The objective of the study was to evaluate the prevalence and proportions of antibiotic-resistant species in periodontitis patients. METHODS: A systematic scoping review of randomized clinical trials (RCTs) was conducted using the PRISMA extension for scoping reviews involving different databases. MeSH terms and keywords were provided to examine only RCTs with antibiotic-resistant results that included at least 3 months of follow-up of systematically healthy patients diagnosed with periodontitis and treated with systemic or local antibiotics adjunctive to subgingival debridement. RCTs that managed participants surgically, duplicate publications, and investigations implemented on animals were discarded. RESULTS: Six RCTs were chosen. These studies included 465 patients. Most investigations observed that while Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Porphyromonas gingivalis had low resistance to amoxicillin, microorganisms in many sites showed resistance to tetracycline, metronidazole, and azithromycin pretreatment. A. actinomycetemcomitans showed high resistance to tetracycline pre- and post-therapy. The proportion of antibiotic-resistant samples augmented rapidly after the prescription of antibiotics in all test groups. The percentage of antibiotic-resistant microorganisms decreased over time; at the end of the follow-up period, resistance levels were close to baseline levels. CONCLUSIONS: Adjunctive local and systemic antibiotic treatment temporarily increased the antibiotic resistance of subgingival microorganisms; nonetheless, many bacteria remained susceptible to antibiotics during their administration.

OBJECTIVES: To assess the efficacy and adverse events linked to the utilization of fentanyl for perioperative pain management in dentistry. METHODS: This systematic review of randomized clinical trials (RCTs) adhered to the PRISMA guidelines and incorporated various databases. RESULTS: Eleven RCTs studying 674 patients were analyzed. Perioperative pain was predominantly evaluated in patients undergoing surgery for impacted molars, although some studies also included patients with other conditions such as oral submucous fibrosis, maxillary cancer, bony temporomandibular joint ankylosis, irreversible pulpitis, among others. Combined with dexmedetomidine, fentanyl produced enhanced analgesic effects. It demonstrated comparable efficacy when compared to nefopam and nalbuphine. Both intranasal and intravenous administration routes proved equally effective. In four RCTs, the transdermal fentanyl patch outperformed the control group, except in the clinical trial where it was compared to ropivacaine. The main adverse events associated with the use of fentanyl included nausea, vomiting, drowsiness, delirium, and respiratory depression; however, they were like those reported in the comparison groups. CONCLUSIONS: While fentanyl demonstrated satisfactory perioperative analgesic efficacy, there were other alternatives that displayed better or comparable outcomes. Due to the risks and potential for misuse of fentanyl, these alternatives must be considered although adverse events were also reported.
RESUMO
Background and Objectives: Staphylococcus aureus is a prevalent bacterium capable of inducing various infections, including skin and soft tissue infections, bloodstream infections, pneumonia, and surgical site infections. The emergence of antimicrobial resistance in S. aureus, particularly methicillin-resistant S. aureus, has raised substantial concerns within global healthcare settings. Prior to antibiotic prescription, the ideal approach is antimicrobial susceptibility testing (AST); however, this is frequently perceived as excessively complex and time-intensive. Lab-on-a-chip (LOC) technology holds promise in addressing these challenges and advancing fundamental microbiological research while also aiding in the development of therapeutic strategies. This systematic review aims to evaluate the potential utility of LOC for AST of S. aureus. Materials and Methods: This study adhered to the PRISMA guidelines. Various databases, including SCOPUS, PubMed/MEDLINE, SCIELO, and LILACS, in addition to gray literature sources, were employed in the review process. Results: Sixteen studies were included in this systematic review. All these studies detailed the effectiveness, rapidity, and predictability of LOC systems for assessing S. aureus susceptibility to various antibiotics. When comparing the LOC approach to traditional manual methods, it was evident that LOC requires a minimal quantity of reagents. Furthermore, most studies reported that the entire LOC procedure took 10 min to 7 h, with results being equally accurate as those obtained through traditional AST protocols. Conclusions: The potential application of LOC for AST of S. aureus is emphasized by its ability to provide rapid access to minimum inhibitory concentration data, which can substantially aid in selecting the most suitable antibiotics and dosages for treating challenging infections caused by this microorganism. Moreover, the rapid AST facilitated by LOC holds promise for enhancing the appropriateness and efficacy of therapy in clinical settings.

Background and Objectives: The necessity for less invasive and patient-friendly surgical therapies guided the development of the "minimally invasive surgical technique" (MIST). The aim of this systematic review was to evaluate the efficacy of MIST for soft tissue management considering aesthetic results, postoperative morbidity, and clinical outcomes. Materials and Methods: Several databases were used to conduct a thorough analysis of the scientific evidence. To investigate randomized clinical trials (RCTs), MeSH terms and keywords were provided. Results: Eleven RCTs were chosen. These experiments included 273 patients. The trials that explored MIST for papilla preservation presented greater efficacy in increasing papillary height (p < 0.05). MIST showed stable clinical outcomes for the management of excessive gingival display and with a flapless technique for single implant placement. Considering the treatment of gingival recessions, some RCTs presented greater root coverage with MIST (p < 0.05), while other trials did not show differences between groups. Regarding aesthetic perception, five RCTs indicated high patient satisfaction with MIST (p < 0.05). Similarly, six RCTs reported that patients in the MIST group presented significantly less post-surgical pain and lower wound healing scores (p < 0.01). Conclusions: It was concluded that using MIST resulted in more clinical studies reporting better clinical outcomes. Considering aesthetic appearance, slightly more than half of the clinical trials also showed improved results with MIST. Likewise, regarding postoperative morbidity, 60% of the clinical trials also described better scores with MIST. All of this indicates that MIST is a good alternative for the management of soft tissues.

OBJECTIVES: To evaluate the prevalence and proportions of bacteria resistant to antiseptics used in dentistry. METHODS: A review of randomized clinical trials (RCTs) was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews involving different databases. MeSH terms and keywords were provided to examine only RCTs with antiseptic-resistant results. RESULTS: Five RCTs were included. These investigations analysed 442 patients. Concerning the prevalence and proportion of species resistant to antiseptics, it was found that the chlorhexidine group showed a statistically significant increase in Streptococcus mutans and Lactobacillus acidophilus counts indicating bacterial resistance (p < 0.001). Moreover, Veillonella species showed resistance to triclosan at the commencement and during the RCTs, and a slight increase in the proportion of resistant strains was observed. Porphyromonas gingivalis, Staphylococcus aureus, and Pseudomonas aeruginosa did not show resistance to cetylpyridinium chloride. Similarly, it was no observed resistance to medicinal herbal plant formulations. CONCLUSIONS: Resistance of S. mutans and L. acidophilus to chlorhexidine was observed, this resistance increased during the follow-up period. Similarly, although in a slight proportion, an increase in the resistance of Veillonella spp. to triclosan during the study period was also described. No microorganisms resistance was observed to any of the other antiseptics studied.

This article analyzes the bioethical implications of using a control/placebo group when conducting clinical trials (CTs) investigating the treatment of periodontitis. For this, the deductive method was used, proposing the interrelation of values, and a scoping systematic review was carried out. A total of 53% of the CTs reviewed were performed in low- and middle-income (LMI) countries, and 92% used a control/placebo group as a comparison group. Although there is a gold standard for the adjunctive treatment of periodontitis, the research ethics committees of most of the analyzed studies approved the use of control/placebo groups for the performance of CTs that did not explore new therapeutic alternatives. In some cases, the CT protocols were not approved by ethics committees, nor was informed consent used. In the LMI countries, a shorter period of recruitment was observed for patients who attended universities and public hospitals. Likewise, most of the CTs reviewed had public funding, a significant amount of which came from the pharmaceutical industry. Only one CT reported the low economic and educational level of its participants. Furthermore, none of the authors of the reviewed CTs declared conflicts of interest. Although the axiology of techno-science always takes into account at least the epistemic, technical and economic value systems, the hegemony of the economic values imposed by the pharmaceutical industry is evident in the performance of CTs investigating the treatment of periodontitis in LMI countries.

OBJECTIVES: To assess the association between Gram-negative enteric rods and Pseudomonas with the clinical parameters in peri-implant disease. MATERIALS AND METHODS: Patients treated with implants and diagnosed with peri-implant mucositis and/or peri-implantitis participate in this cross-sectional research. Unusual microorganisms from the implants were recognized using MALDI-TOF mass spectrometry. Linear regression models were applied. RESULTS: A total of 103 implants were evaluated in thirty-one participants. Gram-negative enteric rods/Pseudomonas were observed in 47 implants (46%). Interestingly, there were differences in probing pocket depth (PPD), clinical attachment loss (CA), and bleeding on probing (BOP) between the groups, where implants with the presence of Gram-negative enteric rods/Pseudomonas presented deteriorated clinical parameters (p < .0001). The crude and adjusted linear regression models for PPD in peri-implant mucositis, PPD in peri-implantitis, CA in peri-implantitis, and BOP in peri-implant disease present significant ßs, demonstrating deteriorated parameters (p < .0001) in the presence of Gram-negative enteric rods/Pseudomonas. Besides, the model for CA in peri-implantitis showed that cemented restored reconstructions were statistically significant (p = .009). Additionally, the R2 value in most models indicated a high degree of correlation (>85%). CONCLUSION: The occurrence of Gram-negative enteric rods and Pseudomonas was associated with deteriorated clinical parameters in patients with peri-implant disease.
RESUMO
INTRODUCTION: There is no recognised investigation examining the influence of some lifestyle comportments on academic performance (AP) in forcibly displaced students in higher education. Thus, the frequency of physical inactivity (PI), insufficient sleep (IS), alcohol consumption (AC), drug consumption (DC) and cigarette smoking (CS) and the independent and combined consequences of these habits on AP in forcibly displaced dental students were investigated. MATERIALS AND METHODS: A sample of 185 students was studied (thirty-seven forcibly displaced and 148 non-displaced students). This cross-sectional study used an institutional administrative database that included students' demographic features and lifestyle behaviours. Multivariate analyses were performed to evaluate the independent and combined effects of lifestyle behaviours on AP. RESULTS: PI, IS, AC, DC and CS were observed in 51%, 43%, 83%, 27% and 16% of forcibly displaced students, respectively. Compared with non-displaced students, forcibly displaced students presented higher frequencies for all of these behaviours (P < .05), lower AP (P < .0001) and lower socio-economic status (P = .003). Unadjusted regression models showed independent and significant associations between forcibly displaced students and PI (P = .01), IS (P = .01), AC (P = .01), DC (P < .0001), CS (P = .02) and low AP (P = .006). The multivariate model for AP and forcibly displaced students increased odds by 4.6 times (1.5-11; 95% CI). Moreover, the lifestyle comportments studied were also statistically significant, showing combined effects. The variables of gender and age were not statistically significant in the adjusted model. CONCLUSIONS: This research observed high frequencies of the behaviours analysed in forcibly displaced students. Furthermore, independent and combined effects of them on AP were detected.

AIM: To describe the prevalence, severity and extension of clinical attachment loss (CAL) and to study the predictors in 15- to 19-year-old adolescents from high schools in the Latin America. MATERIALS AND METHODS: A cross-sectional, epidemiological study was performed. The sample included 1070 high school adolescents 15-19 years of age from Santiago de Chile (Chile), Buenos Aires, Córdoba, Mendoza (Argentina), Montevideo (Uruguay), Quito (Ecuador) and Medellín (Colombia). Calibrated examiners performed full mouth, six sites per tooth clinical examination. RESULTS: There was a response rate of 100%. The prevalence of CAL ≥3 mm in ≥1 site was 32.6%, probing pocket depth ≥4 mm was 59.3% and bleeding on probing (BoP) ≥25% was 28.6%. The logistic regression analysis adjusted for cities revealed that smoking (OR = 1.6), attending public school (OR = 2.3) and having a BoP ≥25% (OR = 4.2) were positively associated with CAL ≥3 mm in ≥ 1 site. CONCLUSION: Clinical attachment loss was prevalent in Latin America adolescents and it is associated with smoking, attendance public school and BoP.

Cardiotoxicity associated with lithium is not a common event; however, it is potentially life-threatening, manifesting electrocardiographically with sinoatrial blocks, high-degree atrioventricular blocks, QT prolongation, and ventricular tachyarrhythmias. This case report presents a patient with severe sinus dysfunction in a clinically severe presentation secondary to cardiogenic shock. The patient sought medical attention for a one-week history of non-anginal chest pain, dizziness without syncope, generalized weakness, and somnolence progressing to bedridden status in the days preceding hospital admission. Laboratory findings revealed elevated blood levels of lithium and thyroid-stimulating hormone (TSH), along with concomitant Acute Kidney Injury Network (AKIN) II acute kidney injury. Subsequently, the patient was admitted to the intensive care unit, where persistent extreme sinus bradycardia of 30 bpm (beats per minute) with sinus pauses without ischemic changes was observed. The patient received supportive treatment, including renal replacement therapy, resulting in complete recovery of hemodynamic status without the need for long-term cardiac conduction devices.
RESUMO
The integration of wireless sensors with artificial intelligence could represent a transformative approach in restorative dentistry, offering a sophisticated means to enhance diagnostic precision, treatment planning, and patient outcomes. This systematic review was conducted to pinpoint and assess the efficacy of wireless sensors in restorative dentistry. The search methodology followed the guidelines outlined by PRISMA and involved the utilization of prominent scientific databases. Following the final phase of evaluating eligibility, the systematic review included six papers. Five experiments were conducted in vitro, while one was a randomized clinical trial. The investigations focused on wireless sensors for cavity diagnosis, toothbrush forces, facial mask applications, and physiological parameter detection from dental implants. All wireless sensors demonstrated efficacy in achieving the objectives established by each study and showed the validity, accuracy, and reproducibility of this device. The investigations examined in this systematic review illustrate the potential of wireless sensors in restorative dentistry, especially in the areas of caries detection, dental implant systems, face masks, and power brushes. These technologies hold promise for enhancing patient outcomes and alleviating the workload of dental practitioners.
RESUMO
Radiography facilities face challenges with the positioning of digital radiography detectors. This study evaluates the image quality, radiation dose, and patient comfort associated with wireless sensors in digital radiography. A systematic exploration was performed across PubMed/MEDLINE, EMBASE, SCOPUS, Web of Science, and SCIELO. Nine papers met the eligibility criteria, including three observational studies with 111 patients, four in vitro experiments with 258 extracted human teeth, and two ex vivo investigations with 16 cadaver mandibles. All studies consistently reported high-quality images produced by wireless sensors. Two studies demonstrated the superiority of wireless sensors, one found comparable accuracy with conventional radiography, and another indicated similar image quality among the sensors. Both wireless and wired sensors significantly reduced radiation doses compared to conventional X-rays. The Visual Analog Scale (VAS) did not reveal a clear superiority of wireless over wired sensors, though both were generally less comfortable than traditional film. The wireless sensors consistently produce high-quality images, comparable to or superior to other digital devices. Both wireless and wired sensors significantly reduce radiation doses compared to conventional X-rays, emphasizing their safety and efficacy. Patient comfort levels vary, with neither sensor type showing clear superiority over the other, and both being less comfortable than traditional film.
RESUMO
Antiphospholipid syndrome (APS) is characterized by the occurrence of thrombotic events and/or obstetric complications in the presence of antiphospholipid antibodies. It is considered one of the most common acquired thrombophilias. The presentation of stroke in patients with APS has been described in some studies; however, it is not frequent enough and there is not much information available regarding the indications for pharmacological thrombolysis and the safety of thrombolytic treatment. Likewise, current evidence does not describe contraindications to thrombolytic therapy in cases of this diagnosis, which makes management with fibrinolysis safe in these cases. A clinical case of stroke is presented in which pharmacological thrombolysis is performed with a successful outcome, without complications of angioedema or bleeding. Likewise, concerning the case, the main neurological manifestations associated with APS, especially in its association with stroke, are described.
RESUMO
Objective: This study aimed to perform a histological evaluation of teeth diagnosed with internal root resorption. Materials and Methods: A descriptive study involved the examination of 50 human teeth extracted due to an unfavorable prognosis for retention in the oral cavity. Teeth were preserved in 10% buffered formalin and subsequently subjected to the decalcification process. Masson-Goldner staining was applied for comprehensive histological assessment. Results: In all the 50 teeth examined, resorption gaps within the dentin tissue were identified, accompanied by the presence of reparative cells in the vicinity of these cavities. Marked structural loss and dentin fragmentation were evident, with regions exhibiting fissures and an absence of dentinal tubules. Conclusions: The histological evaluation of 50 teeth diagnosed with internal dental resorption revealed significant structural alterations, including resorption lacunae, the presence of multinucleated osteoclast-like cells, and reparative connective tissue. These findings highlight the complex and multifaceted nature of internal dental resorption. These histological insights provide a deeper understanding of the pathological processes involved in internal dental resorption and underscore the necessity for early detection and intervention to mitigate tooth loss and preserve dental health.
