Establishment and validation of the autophagy-related ceRNA network in irreversible pulpitis.

BACKGROUND: The molecular mechanisms underlying the onset and progression of irreversible pulpitis have been studied for decades. Many studies have indicated a potential correlation between autophagy and this disease. Against the background of the competing endogenous RNA (ceRNA) theory, protein-coding RNA functions are linked with long noncoding RNAs (lncRNAs) and microRNAs (miRNAs). This mechanism has been widely studied in various fields but has rarely been reported in the context of irreversible pulpitis. The hub genes selected under this theory may represent the key to the interaction between autophagy and irreversible pulpitis. RESULTS: Filtering and differential expression analyses of the GSE92681 dataset, which contains data from 7 inflamed and 5 healthy pulp tissue samples, were conducted. The results were intersected with autophagy-related genes (ARGs), and 36 differentially expressed ARGs (DE-ARGs) were identified. Functional enrichment analysis and construction of the protein‒protein interaction (PPI) network of DE-ARGs were performed. Coexpression analysis was conducted between differentially expressed lncRNAs (DElncRNAs) and DE-ARGs, and 151 downregulated and 59 upregulated autophagy-related DElncRNAs (AR-DElncRNAs) were identified. StarBase and multiMiR were then used to predict related microRNAs of AR-DElncRNAs and DE-ARGs, respectively. We established ceRNA networks including 9 hub lncRNAs (HCP5 and AC112496.1 ↑; FENDRR, AC099850.1, ZSWIM8-AS1, DLX6-AS1, LAMTOR5-AS1, TMEM161B-AS1 and AC145207.5 ↓), which were validated by a qRT‒PCR analysis of pulp tissue from patients with irreversible pulpitis. CONCLUSION: We constructed two networks consisting of 9 hub lncRNAs based on the comprehensive identification of autophagy-related ceRNAs. This study may provide novel insights into the interactive relationship between autophagy and irreversible pulpitis and identifies several lncRNAs that may serve as potential biological markers.

Management of odontostomatological emergencies during the covid19 pandemic at the General Hospital Grand Yoff in Dakar

Objective: Describe the sociodemographic, clinical and therapeutic aspects of the patients received for an emergency, during this period of pandemic, in a service of reference the service of odontostomatology General Hospital Grand Yoff of Dakar. Patients and Methods: This was a descriptive cross-sectional study over a threemonth period from March 3 to June 3, 2020. Referred and non-referred patients received for odontostomatological emergencies were included in the study. The data collected were entered in Excel and analyzed using SPSS20.0 software with Chi2 tests performed between certain variables with a significance level set at 0.05. Result(s): Non-referred patients represented 64.9% (n = 131) of the study population and referred patients 35.1% (n = 71). Emergencies were infectious in 74.7% (n = 151) of cases and traumatic in 14.3% (n = 29). Acute apical periodontitis was encountered in 44.6% (n = 90), cellulitis in 16.4% (n = 33) and pulpitis in 9.4% (n = 19) of cases. Therapeutic attitudes were dominated by dental avulsion in 56.4% (n = 114) of cases, pulp sedation in 9.4% (n = 19) of cases and mono-maxillary restraint in 8.4% (n = 17) of cases. Conclusion(s): Despite the risk of contamination and possible dissemination of the covid19 virus, the continuity of oral care must be ensured because of the emergencies that can jeopardize the functional or even vital prognosis of patients. Certain recautions must therefore be taken at the level of the structures of care of these affections.Copyright © 2021

Acupuncture for Management of Endodontic Emergencies: a Review.

Root canal treatment (RCT) employed for painful endodontic conditions like apical periodontitis and irreversible pulpitis is associated with a high incidence of postoperative pain. Pharmacological management for this purpose is effective, but not entirely free from side effects and in some cases may fail to provide adequate relief. Furthermore, concerns have been raised regarding the transmission of coronavirus disease-2019 (COVID-19) as a result of the aerosols generated and prolonged chair side time required for RCT. Acupuncture is a traditional Chinese therapy commonly employed as an alternative for the treatment of pain. And what's more, the use of acupuncture has been recently reported as treatment for the management of endodontic pain as well as on the anesthetic success in patients with irreversible pulpitis. This review aims to evaluate the current evidence for acupuncture in endodontics and its potential role in emergency pain relief and management for patients. To combat this, a thorough search for literature within the field was performed in five electronic databases. Retrieved studies were screened according to the pre-defined eligibility criteria. After both an electronic and manual search, five studies were selected for review. These studies reported the beneficial effects of acupuncture in reducing the failure of nerve block in patients with irreversible pulpitis and in controlling both intraoperative and postoperative pain following RCT. In addition, it was also reported to reduce anxiety surrounding the dental procedure and minimized the intake of analgesics after the endodontic procedure, which can result in some unwanted side effects. However, more in depth clinical research is required before any recommendation regarding the application of acupuncture in endodontic patients can be made.

Assessment of Endodontic Emergency Care in a COVID-19 Pandemic

Objective: This study compared the aerosol-generating and non-aerosol-generating endodontic emergency procedures' success and assessed the outcome of endodontic treatments initiated before a pandemic but could not be completed in the targeted time. Material(s) and Method(s): Emergency treatments were performed according to symptoms of teeth. Treatment success or failure was determined according to patients whether not re-referral with untimely pain. Short-term outcome and complications arising from teeth, which endodontic treatments were prolonged were also recorded. A chi-square test was used in the statistical analysis, and p<0.05 was considered significant. Result(s): The aerosol-generating procedure group's success rate was 86.2%, while it was 70.0% in the non-aerosol generating procedure group (p=0.050). The short-term survival rate of teeth was 83.7% in patients whose endodontic treatment had been prolonged. Conclusion(s): Considering the pros and cons, each emergency patient should be evaluated case-by-case. Copyright ©Meandros Medical and Dental Journal, Published by Galenos Publishing House.

Emergency Pain Management of Untreated Pulpitis during COVID-19 Lockdown by Telephonic Communication

To evaluate the beneficial effects of orally administered corticosteroids in alleviating the pain of symptomatic pulpitis. Materials and Methods: Out of the 87 patients who contacted the expert panel telephonically during the period of COVID-19 lockdown, 55 patients complaining of moderate to severe dental pain were included in the study and thus advised to take oral tablets of paracetamol 650 mg postmeal thrice a day for 3–5 days along with a single oral dose of 4 mg of dexamethasone. The patients were asked to report their pain status after every 24 hours for at least 72 hours. In case of severe pain not controlled by these medicines even after 3 days, two tablets of dispersible ketorolac tromethamine (10 mg) were advised once on the fourth day, followed by a single tablet three times a day for another 3 days. In case the pain did not subside within 3 days of taking the second line of treatment, or there was a development of swelling/lymphadenopathy, the patient was advised to get the tooth extracted. Results: Out of 55 patients taking a single dose of dexamethasone, 47 (85.45%) patients reported a “significant” reduction of pain within 24–72 hours. The remaining eight patients (14.55%) in which severe pain was not controlled by paracetamol and dexamethasone even after 3 days, two tablets of ketorolac tromethamine (10 mg) were advised. Six patients (75%) reported a “significant” reduction in the pain, while two (25%) patients still in pain were advised tooth extraction and were referred to the emergency department of the tertiary care center. Conclusion: For the pain felt by patients diagnosed with symptomatic irreversible pulpitis, systemic corticosteroids administration is an adequate strategy in controlling pain for up to 48–72 hours, the time during which the pain is felt most. © The Author(s). 2022.

Acral peeling as the sole skin manifestation of COVID-19 in children.

Skin lesions in children with proven COVID-19 are not frequent in the literature apart from those associated with multisystem inflammatory syndrome. Fortunately, microbiologic testing for SARS-CoV-2 has become widely available not only for admitted patients but also for mild cases. We present a series of 6 children with mild erythema and desquamation of the fingertips and/or toes as the only skin manifestation of COVID-19. As all children had asymptomatic to mildly symptomatic disease, it is reasonable to consider this a sign of benign disease and favorable outcome.

Dental care during the coronavirus disease 2019 (COVID-19) outbreak: operatory considerations and clinical aspects.

OBJECTIVES: This paper is aimed at addressing the urgent need to develop a protocol that will address the operatory and clinical aspects of dental care during the Coronavirus disease 2019 (COVID-19) outbreak. DATA SOURCES: The epidemiology, clinical signs and symptoms, and modes of transmission of COVID-19 are presented. This protocol was established as an international collaboration of three dental universities: Hadassah School of Dental Medicine, Israel; University of Rochester Medical Center, USA; and the University of Pennsylvania, USA. This protocol is based on a detailed review of the existing English language literature as well on the logistic and clinical experience of each facility and the opinion of the authors. The protocol is designed for a hospital setting and includes considerations related to dental treatment in both healthy subjects and those suspected or diagnosed with COVID-19. The first part of this review discusses operatory considerations; the second part discusses general dental clinical aspects; the third part discusses endodontic considerations; and the fourth part discusses surgical aspects. This protocol may be applicable to other future similar pandemics. CONCLUSION: Logistic and clinical steps are required to provide dental care during the COVID-19 outbreak while preventing cross-contamination and protecting the dental team during the provision of care.
