Background: Systemic health conditions can significantly influence oral health and are often associated with tooth loss and specific dental complaints. These diseases may accelerate periodontal breakdown or complicate existing oral conditions, thereby shaping patients' chief complaints and their reasons for seeking dental care. Objective: To assess the impact of systemic conditions on reasons for tooth extraction and evaluate the prevalence of these conditions within the study population. It also documented the most common chief complaints, categorized by gender, age, and systemic conditions. Methods: This prospective cross-sectional study was conducted amongst the Iraqi population, involving a total of 2,581 patients who attended the Oral and Maxillofacial Surgery Department for tooth extraction. Results: The most common chief complaint was a need for prostheses (43%), followed by dental pain (28.4%). Amongst the 2,581 patients, 659(25.5%) had controlled systemic diseases. The most frequently reported condition was hypertension (12.63%), then diabetes (9.33%), thyroid disease (2.24%), ischemic heart disease (2.16%), and respiratory disease (2.05%). A highly significant relationship was observed between diabetes and periodontal diseases, as indicated by the chi-square test (p= 0.004). Conclusions: This study offers the first epidemiological insights into the impact of systemic diseases on the reasons for tooth extractions among the Iraqi population. The findings reveal a significant correlation between specific systemic conditions and oral health issues that ultimately lead to tooth extraction. Additionally, the study underscores the high prevalence of medically compromised individuals.

Objective: In this overview, we present compelling evidence from multiple systematic reviews and meta-analyses (SRMAs) and examine the prognostic role of the PD-L1/PD-1 axis, as well as the potential of personalized treatment strategies targeting this axis, in patients with oral squamous cell carcinoma (OSCC) and oral potentially malignant disorders (OPMDs). Methods: Six databases were searched to retrieve systematic review and meta-analysis studies. The population of interest was patients with OSCC and OPMDs in whom the expression of PD-L1 and PD-1 had been investigated. At least one of the following outcomes was reported, along with at least one clinicopathological feature: overall survival, disease-free survival, or disease-specific survival. All studies were assessed for risk of bias using the AMSTAR 2 tool. Results: A total of 195 studies were found through the initial search, and after duplicate removal, 97 studies were screened by title and Finally, five systematic reviews and meta-analysis studies fit our inclusion criteria and were included in this review. Conclusions: Based on two published systematic reviews, our study revealed a lack of evidence for the prognostic value of PD-L1 in improving overall survival in oral cancer patients. However, it showed a correlation with specific clinicopathological features such as sex, lymph node metastasis, and HPV status.

Animal models of thrombosis play a critical role in research, helping us understand the mechanisms of hemostasis and thrombus formation, as well as in the screening of anti-thrombotic drugs. This study aimed to evaluate the safety profile of two anticoagulants in murine research and to assess coagulation parameters, including prothrombin time (PT) and activated partial thromboplastin time (aPTT), using the VETSCAN^® VSpro coagulation analyzer in wild-type (C57BL/6) mice following administration of anticoagulants. Two experiments were conducted involving a total of sixty wild-type mice that received two common anticoagulants. Warfarin was administered in the drinking water at varying dosages, while dabigatran was incorporated into a custom-chow diet at two dosages (10 mg/g and 15 mg/g chow). The VSpro was used to establish a reference range for PT and aPTT values in untreated wild-type mice and to monitor coagulation changes in mice undergoing anticoagulant therapy. Dabigatran was well tolerated at both concentrations (10 mg/g and 15 mg/g chow), while warfarin was safe at a concentration of 2.5 mg/L, resulting in a doubling of PT and aPTT compared to baseline levels. Although the VSpro effectively detected coagulation abnormalities in murine models, certain limitations were observed, including out-of-range measurements in cases of coagulopathy. This study provides insights into safe anticoagulant dosages for murine models, supporting the use of dabigatran at 10 mg/g and 15 mg/g chow and warfarin at 2.5 mg/L. The VSpro analyzer was able to monitor coagulation parameters under these conditions, making it a feasible tool for murine research.

Background and Aims: An effective surgical adhesive must possess strength, biodegradability, flexibility, non‐toxicity, and the ability to accommodate to tissue movement. However, existing adhesives in the market lack some of these crucial properties. Both synthetic cyanoacrylate and natural fibrin glue have been explored for sutureless oral surgery, but they come with specific limitations. This perspective review aims to explore the novel potential of hydrogels as bioadhesives for wound closure in the oral cavity.Methods: This review thoroughly examines the properties, applications, and limitations of hydrogels as bioadhesive materials for wound closure within the human body.Results: We first provide a comprehensive description of materials used for sutureless oral surgery. Next, drawing on our expertise in the field of oral surgery, we propose novel potential applications for hydrogels in oral wound closure. We showed that Hydrogels represent promising bioadhesives in medical field and are undergoing continuous enhancement to expand their applications in wound closure.Conclusion: Although hydrogels have been utilized in various dental conditions, their potential for closing wounds in the oral cavity remains unexplored.

Data sources There is a discrepancy in the databases and data sources mentioned by the authors. The abstract references four databases, which differ from those listed in the materials and methods section. According to the methods, the literature search was conducted across three databases: PubMed-MEDLINE, EMBASE, and Scielo. However, the abstract mentions four databases, including MEDLINE/PubMed, Wiley Online Database, Web of Science, and Scopus. Study selection All relevant articles were searched using specific keywords derived from Medical Subject Headings (MeSH) terms and text words (TW) related to the topic. Following the screening of titles and abstracts, the full texts of the selected studies were reviewed, and inclusion and exclusion criteria were applied. Any disagreements regarding study inclusion were resolved by consensus. Studies that reported data on antibiotic prescription patterns by dentists for the treatment of apical disease were included. Data extraction and synthesis Data extraction was carried out by three independent reviewers, with a fourth author resolving any disagreements. Extracted data included publication details (authors, year of publication), number of respondents, response rate, survey location, and prescriber type (general practitioner, endodontist, or dental surgeon). The primary outcome measured was the percentage of dentists prescribing antibiotics for each form of periapical endodontic disease. Results The search strategy identified a total of 96 studies, of which 39 cross-sectional studies met the inclusion criteria. Dentists prescribed antibiotics in 25.8% of cases of symptomatic apical periodontitis (AP) and in 31.5% of asymptomatic AP cases. In instances of acute symptomatic apical abscess with swelling and moderate to severe symptoms, approximately 89% of dentists prescribed antibiotics, compared to nearly 100% of endodontists. Conclusions Endodontists demonstrate more appropriate antibiotic-prescribing practices than general practitioners. Globally, dentists tend to over-prescribe antibiotics for managing apical disease. Therefore, there is a pressing need to enhance antibiotic prescribing practices in the treatment of endodontic infections.

The prevalence of diseases characterised by eosinophilia is on the rise, emphasising the importance of understanding the role of eosinophils in these conditions. Eosinophils are a subset of granulocytes that contribute to the body’s defence against bacterial, viral, and parasitic infections, but they are also implicated in haemostatic processes, including immunoregulation and allergic reactions. They contain cytoplasmic granules which can be selectively mobilised and secrete specific proteins, including chemokines, cytokines, enzymes, extracellular matrix, and growth factors. There are multiple biological and emerging functions of these specialised immune cells, including cancer surveillance, tissue remodelling and development. Several oral diseases, including oral cancer, are associated with either tissue or blood eosinophilia; however, their exact mechanism of action in the pathogenesis of these diseases remains unclear. This review presents a comprehensive synopsis of the most recent literature for both clinicians and scientists in relation to eosinophils and oral diseases and reveals a significant knowledge gap in this area of research.

Oral squamous cell carcinoma (OSCC) is the most common head and neck cancer. There is mounting evidence to suggest that several components of the coagulation system directly affect carcinogenesis. Our recent in vitro studies demonstrated, for the first time, that various anticoagulants have anticancer effects on OSCC. They also showed the need for the immediate translation of these experimental conditions from bench to preclinical animal models. Here, we carried out a systematic review to summarise existing evidence on murine models built around the interactions between anticoagulants and oral cancer. Only one preclinical murine study was included in our systematic review, investigating the role of heparins in tumour pathophysiology. The paucity of evidence regarding the interactions between oral squamous cell carcinoma and anticoagulants emphasises the urgency with which further preclinical research should be conducted.

Tongue abscess is a serious clinical entity which scarcely affects the tongue. It should be treated urgently to prevent airway obstruction or dissemination of infection to a more deep or distant area of the body. This article presented the first clinical report of tongue abscess in Iraq which discussed its clinical presentation, diagnosis, and treatment with a review of literature.
