Comparison of Immunohistochemical Markers in Oral Submucous Fibrosis and Oral Submucous Fibrosis Transformed to Oral Squamous Cell Carcinoma-A Systematic Review and Meta-Analysis.
The objective of the study was to compare the expression of immunohistochemical (IHC) markers of oral submucous fibrosis (OSMF) (non-transformed group) to those of oral squamous cell carcinoma (OSCC) transformed from OSMF (transformed group). The search for comparative cross-sectional studies was carried out in PubMed and Scopus abiding to the PICO criteria, where expression of IHC markers in OSMF were compared with that of OSCC transformed from OSMF. The cellular distribution, number of positive cases, staining intensity, and mean immunoreactive score (IRS) of each IHC marker were evaluated in both groups. A total of 14 studies were included in the systematic review, in which immunoexpression of 15 epithelial and 4 connective tissue biomarkers were evaluated. Expression of β1-integrin, OCT-3, CD1a, CD207, survivin, Dickkopf-1, COX-2, hTERT, CTGF, MDM2, Ki-67, and α-SMA were increased during transformation of OSMF to OSCC. Conversely, expression of PTEN and lysyl oxidase decreased during transformation of OSMF to OSCC. Expression of a group of epithelial markers, such as COX2, hTERT, CTGF, survivin, MDM2, and p53, was 38 times lower in the non-transformed group cases compared to transformed group cases (95% CI: 58% to 10%; = 0.01; and I = 90%). Meta-analysis of all markers involved in cell metabolism/apoptosis, which included β1-integrin along with the above markers also suggested 42 times lower expression in the non-transformed group as compared to the transformed group (95% CI: 58% to 10%; = 0.01; and I = 90%). Sub-group analyses on cytoplasmic and nuclear epithelial markers were inconclusive. Meta-analysis of connective tissue markers was also inconclusive. No publication bias was found. Instead of delving into numerous markers without a strong basis for their use, it is advisable to further study the markers identified in this study to explore their clinical utility.

Review
This systematic review aimed to synthesize and analyze a collection of studies focused on comparing conventional veneers (CVs) and minimal or no-preparation veneers (MPVs) within the domain of prosthodontics. The review sought to explore various attributes, techniques, outcomes, and considerations associated with these two approaches. The key aspects investigated included esthetics, longevity, periodontal health, patient satisfaction, structural influences such as microleakage and marginal fit, cement thickness, and color stability. A systematic literature search was conducted to identify relevant studies published up to the present date. Studies meeting specific inclusion and exclusion criteria were selected for review. Studies pertaining to various methodologies were identified initially as part of the strategy and bias assessment was performed to determine the credibility of their assessments before inclusion in this review. Four comparative assessments gleaned from the selected studies provided a comprehensive overview of the strengths and limitations associated with CVs and MPVs. MPVs demonstrated advantages such as enhanced survival rates and extended mean success periods, implying their potential as viable long-term restorative options. Meticulous patient management and optimal preparation techniques emerged as crucial factors influencing successful outcomes. Structural attributes, including microleakage and marginal fit, varied depending on the preparation techniques employed. Moreover, considerations related to color changes in veneers underscored the intricate interplay between material properties and fabrication methods. The insights underscore the significance of patient-centric care, precision preparation methodologies, and material choices in guiding successful outcomes. However, the diverse methodologies and constraints of certain studies warrant careful interpretation. This study accentuates the potential for future research directions, interdisciplinary collaboration, and the advancement of evidence-based practices within veneer dentistry.

Review
The period of pregnancy is characterized by a multitude of diverse changes that exert a notable impact on the oral cavity of women. During this gestational phase, patients necessitate tailored oral care and specific recommendations to preempt and address potential oral diseases. This systematic review aimed to perform a detailed analysis of the research studies that focused on the oral manifestations observed in pregnant women. A meticulous search was conducted in the databases Medline, Scopus, and Scielo by employing the following search terms: ((pregnant OR pregnancy)) AND (("oral manifestation*") OR ("oral health")). Articles that were published between 2013 and 2023 and written in English or Spanish and studies that scrutinized oral manifestations in pregnant women and included a diagnosis conducted by a qualified dentist were selected; we excluded articles published before 2013, articles that could not be accessed in full text, studies whose patients were not pregnant women at the time of the study, studies where patients were selected because they had a specific disease, studies where the clinical examination was not performed by a dentist, and articles written in languages other than English or Spanish. Subsequently, the risk of bias in the chosen articles was assessed in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) scale. A total of 20 studies were included in the analysis, following the exclusion and inclusion criteria. These studies were categorized as cross-sectional, cohort, longitudinal, or case-control. Various oral manifestations in pregnant women were examined, with five studies comparing these manifestations with those observed in nonpregnant women. The most prevalent oral manifestations associated with pregnancy encompass dental caries, periodontitis, gingivitis, pyogenic granuloma, and candidiasis. Nonetheless, less common lesions may also emerge during the course of pregnancy.

Review
Fibroblast activation protein inhibitor (FAPI) is a promising tracer in oncologic positron emission tomography/computed tomography (PET/CT). Numerous studies have demonstrated the superior sensitivity of FAPI PET/CT over fluorodeoxyglucose (FDG) PET/CT in several types of cancer. However, the cancer specificity of FAPI uptake remains understudied, and several cases of false-positive FAPI PET/CT findings have been reported. A systematic search of PubMed, Embase, and Web of Science was conducted for studies published prior to April 2022 reporting nonmalignant FAPI PET/CT findings. We included original peer-reviewed articles of studies in humans using FAPI tracers radiolabeled with Ga or F that were published in English. Papers without original data and studies with insufficient information were excluded. Nonmalignant findings were presented on a per-lesion basis and grouped according to the type of organ or tissue involved. The search identified a total of 1.178 papers, of which 108 studies were eligible. Eighty studies were case reports (74%), and the remaining 28 were cohort studies (26%). A total of 2.372 FAPI-avid nonmalignant findings were reported, with the most frequent being uptake in the arteries, e.g., related to plaques (n = 1178, 49%). FAPI uptake was also frequently related to degenerative and traumatic bone and joint lesions (n = 147, 6%) or arthritis (n = 92, 4%). For organs, diffuse or focal uptake was often seen in cases of inflammation, infection, fibrosis, and IgG4-related disease (n = 157, 7%). FAPI-avid inflammatory/reactive lymph nodes (n = 121, 5%) and tuberculosis lesions (n = 51, 2%) have been reported and could prove to be potential pitfalls in cancer staging. Periodontitis (n = 76, 3%), hemorrhoids (n = 47, 2%), and scarring/wound healing (n = 35, 2%) also presented as focal uptake on FAPI PET/CT. The present review provides an overview of the reported FAPI-avid nonmalignant PET/CT findings to date. A large number of benign clinical entities may show FAPI uptake and should be kept in mind when interpreting FAPI PET/CT findings in patients with cancer.

Review
In addition to their recognized value for obtaining 3D digital dental models, intraoral scanners (IOSs) have recently been proven to be promising tools for oral health diagnostics. In this work, the most recent literature on IOSs was reviewed with a focus on their applications as detection systems of oral cavity pathologies. Those applications of IOSs falling in the general area of detection systems for oral health diagnostics (e.g., caries, dental wear, periodontal diseases, oral cancer) were included, while excluding those works mainly focused on 3D dental model reconstruction for implantology, orthodontics, or prosthodontics. Three major scientific databases, namely Scopus, PubMed, and Web of Science, were searched and explored by three independent reviewers. The synthesis and analysis of the studies was carried out by considering the type and technical features of the IOS, the study objectives, and the specific diagnostic applications. From the synthesis of the twenty-five included studies, the main diagnostic fields where IOS technology applies were highlighted, ranging from the detection of tooth wear and caries to the diagnosis of plaques, periodontal defects, and other complications. This shows how additional diagnostic information can be obtained by combining the IOS technology with other radiographic techniques. Despite some promising results, the clinical evidence regarding the use of IOSs as oral health probes is still limited, and further efforts are needed to validate the diagnostic potential of IOSs over conventional tools.

Meta-Analysis
Although periodontal diseases have been widely reported in patients with juvenile idiopathic arthritis (JIA), their association with JIA remains controversial. This systematic review and meta-analysis aimed to evaluate the association between JIA and periodontal diseases to facilitate oral health management and periodontal disease prevention in JIA patients. We conducted a comprehensive search of Web of Science, Cochrane Library, PubMed, Embase, Chinese Scientific and Technological Journal (VIP) database, Wan Fang Data, China National Knowledge Infrastructure (CNKI), and China Biomedical Literature Database (CBM) up to 30 September 2022, without publication dates or language restrictions. Two authors independently evaluated observational studies for inclusion, and the quality of the included studies was assessed using the Newcastle Ottawa Scale (NOS) and the Agency for Healthcare Research and Quality (AHRQ). Continuous variables are presented as mean difference (MD) and 95% confidence interval (CI). Parameters of the simplified oral hygiene index (OHI-S), plaque index (PI), gingival index (GI), clinical attachment loss (CAL), and probing depth (PD) were considered as outcome measures and were compared between JIA patients and healthy controls. The initial search comprised 15 studies with a total of 1537 individuals. The meta-analysis showed the parameters of OHI-S (MD = 0.12, 95% CI: 0.04-0.19, = 0.002), PI (MD = 2.08, 95% CI: 1.67-2.50, < 0.00001), GI (MD = 0.50, 95% CI: 0.17-0.82, = 0.003), CAL (MD = 0.22, 95% CI: 0.01-0.43, = 0.04), and PD (MD = 1.42, 95% CI: 0.08-2.77, = 0.04) in JIA patients were significantly higher than those of healthy controls. All of the included studies were of high quality. This systematic review and meta-analysis showed a possible association between JIA and periodontal diseases. Therefore, it is recommended to continuously pay attention to the periodontal health of JIA patients and fully explore the underlying mechanism.

Meta-Analysis
BACKGROUND
Periodontitis is a common and chronic inflammatory disease characterized by irreversible destruction of the tooth surrounding tissues, especially intrabony defects, which eventually lead to tooth loss. In recent years, stem cell-based therapy for periodontitis has been gradually applied to the clinic, but whether stem cell-based therapy plays a positive role in periodontal regeneration is unclear at present.
METHODS
The clinical studies related to the evaluation of mesenchymal stem cells for periodontal regeneration in PubMed, Cochrane Central Register of Controlled trials (CENTRAL), Web of Science (WOS), Embase, Scopus, Wanfang and China national knowledge infrastructure (CNKI) databases were searched in June 2023. The inclusion criteria required the studies to compare the efficacy of stem cell-based therapy with stem cell free therapy for the treatment periodontitis, and to have a follow-up for at least six months. Two evaluators searched, screened, and assessed the quality and the risk of bias in the included studies independently. Review Manager 5.4 software was used to perform the meta-analysis, and GRADEpro GDT was used to evaluate the level of the evidence.
RESULTS
Five randomized controlled trials (RCTs) including 118 patients were analyzed. The results of this meta-analysis demonstrated that stem cell-based therapy showed better therapeutic effects on clinical attachment level (CAL) (MD = - 1.18, 95% CI = - 1.55, - 0.80, P < 0.00001), pocket probing depth (PPD) (MD = - 0.75, 95% CI = - 1.35, - 0.14, P = 0.020), and linear distance from bone crest to bottom of defect (BC-BD)( MD = - 0.95, 95% CI = - 1.67, - 0.23, P = 0.010) compared with cell-free group. However, stem cell-based therapy presented insignificant effects on gingival recession (P = 0.14), linear distance from cementoenamel junction to bottom of defect (P = 0.05).
CONCLUSION
The results demonstrate that stem cell-based therapy may be beneficial for CAL, PPD and BC-BD. Due to the limited number of studies included, the strength of the results in this analysis was affected to a certain extent. The high-quality RCTs with large sample size, multi-blind, multi-centric are still required, and the methodological and normative clinical study protocol should be established and executed in the future.

Review
is a Gram-negative oral anaerobic bacterium that plays a key role in the pathogenesis of periodontitis. expresses a variety of virulence factors that disrupt innate and adaptive immunity, allowing to survive and multiply in the host and destroy periodontal tissue. In addition to periodontal disease, is also associated with systemic diseases, of which insulin resistance is an important pathological basis. causes a systemic inflammatory response, disrupts insulin signaling pathways, induces pancreatic β-cell hypofunction and reduced numbers, and causes decreased insulin sensitivity leading to insulin resistance (IR). In this paper, we systematically review the studies on the mechanism of insulin resistance induced by , discuss the association between and systemic diseases based on insulin resistance, and finally propose relevant therapeutic approaches. Overall, through a systematic review of the mechanisms related to systemic diseases caused by through insulin resistance, we hope to provide new insights for future basic research and clinical interventions for related systemic diseases.

Review
The gold standard in the non-surgical treatment of periodontitis is scaling and root planing (SRP). In recent years, the use of autogenous platelet concentrates has spread over many specialties in dentistry and, thus, has also been gaining popularity in periodontal treatment. Its two main fractions are platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), which, since 2014, can also be used via injection as injectable platelet-rich fibrin (i-PRF). The authors conducted a comprehensive systematic review in accordance with the PRISMA 2020 guidelines. It involved searching PubMed, Embase, Scopus, and Google Scholar databases using the phrases ("Root Planing" OR "Subgingival Curettage" OR "Periodontal Debridement") AND ("Platelet-Rich Plasma"). Based on the authors' inclusion and exclusion criteria, 12 results were included in the review, out of 1170 total results. The objective of this review was to ascertain the impact of utilizing PRP and i-PRF in SRP. The results revealed that both the incorporation of PRP and i-PRF were found to be significantly associated with are duction in gingival pocket depth and again in clinical attachment level; however, i-PRF demonstrated superiority in improving clinical parameters. Furthermore, i-PRF demonstrated notable bactericidal efficacy against . On the other hand, PRP proved inferior to an Nd:YAG laser in clinical parameter improvement; however, it demonstrated significant efficiency as well. This literature review led the authors to the conclusion that autologous platelet concentrates might be competent agents for improving the therapeutic outcomes of SRP.

Review
In recent years, orthodontics, a specialized branch of dentistry, has evolved considerably in terms of both techniques and materials used. Aimed at correcting dental malocclusions and craniofacial anomalies, it improves the functionality and aesthetics of the face and oral cavity. However, orthodontic treatment, in its developmental stages, may induce oxidative stress (O.S.) phenomena, with an increase in the production of reactive oxygen species (ROS), damaging the dental and periodontal tissues involved, affecting the short-, medium- and long-term results. Studies on the antioxidant effects of natural products (e.g., resveratrol, green tea, turmeric, etc.) in the medical field have aroused considerable interest in recent years. A systematic literature review was conducted on the PubMed, Scopus, and Web of Science databases using natural products (N.P.s), O.S., and orthodontic as keywords. The study aims to consider the determinants of the increase in ROS occurring during orthodontic treatment and the possibility of natural products being able to control and neutralize biochemical phenomena by restoring the physiological process in which the balance between the production of ROS and the ability of the body's antioxidant system to neutralize them is in favor of the latter.
