ABSTRACT
INTRODUCTION: The current evidence linking tooth loss and cardiovascular disease mortality is inconclusive. Thus, the aim of this systematic review was to explore the association between tooth loss and cardiovascular disease (CVD) mortality. METHODS: A comprehensive literature search of databases and gray literature included: Web of Science, Scopus, PubMed, Cochrane Central Register of Controlled Trials, Google Scholar, various digital repositories. The included studies reported on CVD mortality and tooth loss. The Newcastle-Ottawa scale was used to assess the quality of included studies. Random-effects meta-analysis method, sub-group analysis (based on the tooth loss categories (edentulous and fewer than 10 teeth present), meta-regression (based on the number. of confounders), publication bias, and sensitivity analysis were performed. RESULTS: Twelve articles met the eligibility criteria with an overall "Good" quality. A significant association between tooth loss (edentulous or less than 10 teeth present) and CVD mortality was found in the primary meta-analysis, which compiled data from 12 studies. The estimated hazard ratio was 1.66 (95% CI: 1.32-2.09), and there was high heterogeneity (I2 = 82.42). Subgroup analysis revealed that the edentulous subgroup showed a higher risk with no significant heterogeneity, while the subgroup with fewer than 10 teeth showed a higher risk with substantial heterogeneity. Meta-regression analysis did not reveal any significant impact (P = .626) on whether variations in the number of confounders across studies would substantially affect the overall findings. No publication bias was detected and the sensitivity analysis based on the critical confounders also confirmed that tooth loss as a risk factor for CVD mortality (hazard ratio = 1.52, 95% CI: 1.28-1.80), (I2 51.82%). CONCLUSION: The present systematic review reported that being edentulous or having lesser than 10 teeth is a predictive indicator of CVD mortality.

OBJECTIVE: The present systematic review and meta-analysis aimed to evaluate the periodontal health of systemic sclerosis patients compared with non-systemic sclerosis controls. MATERIALS AND METHODS: Online databases were searched for eligible studies on February 24, 2023. The primary outcomes of interest in systemic sclerosis patients and controls included the clinical attachment level, periodontal probing depth, recession depth, plaque index, bleeding on probing score, gingival index, number of teeth with periodontitis, prevalence of periodontitis and gingivitis, and extent and severity of periodontitis. RESULTS: Fourteen studies met inclusion criteria and were incorporated in the qualitative and quantitative analysis. In comparison with the controls, systemic sclerosis patients had a higher prevalence of periodontitis (OR = 7.63 (1.74-33.50), p = 0.04, I2 = 69%), including more severe forms of periodontitis (OR = 6.68 (3.39-13.15), p = 0.85, I2 = 0%), as well as higher periodontal probing depth ((0.88 (0.45-1.31), p = 0.02, I2 = 99%)), clinical attachment level (1.22 (0.8-1.64), p = 0.003, I2 = 98%), and plaque presence (0.83 (0.13-1.53), p = 0.03, I2 = 96%). There was no statistically significant difference in gingival inflammation (1.14 (0.07-2.21), p = 0.04, I2 = 98%). CONCLUSIONS: The systematic review and the meta-analysis showed that systemic sclerosis patients suffer from worse periodontal health than non-systemic sclerosis individuals.

INTRODUCTION: This systematic review aimed to examine a potential link between apical periodontitis (AP) and gastrointestinal diseases (GIDs). METHODS: The protocol of the review has been registered in PROSPERO (CRD42022330771). The following engines were used with the aim of searching for relevant literature: PubMed, Web of Science, Scopus, Cochrane Central Register of Controlled Trials, and grey literature, from inception to May 2022. There were no language restrictions included. Study selection, data collection, and synthesis have been performed by 2 independent reviewers. For the purpose of estimating the quality of studies, the Newcastle-Ottawa Scale was used. RESULTS: Four matched case control studies, as well as a single longitudinal cohort study were included in the final review. These were published between 2012 and 2017, and comprised 537 participants whose age range was 18 to 87 years. It was not possible to perform a meta-analysis due to different study designs and evaluated outcomes of included studies. Except for one study that was categorized as "Good," overall, for 4 out of 5 studies the quality was assessed as "Fair". CONCLUSIONS: This review highlighted sparse knowledge present in the literature concerned with the association between AP and GIDs. Available evidence reveals a potential link between impaired endodontic status, assessed by the number of root-filled teeth with periapical radiolucency, and GIDs. More research is needed to ascertain this association.
ABSTRACT
AIM: To critically evaluate the reporting quality of a random sample of animal studies within the field of endodontics against the Preferred Reporting Items for Animal Studies in Endodontics (PRIASE) 2021 checklist and to investigate the association between the quality of reporting and several characteristics of the selected studies. METHODOLOGY: Fifty animal studies related to endodontics were randomly selected from the PubMed database with publication dates from January 2017 to December 2021. For each study, a score of '1' was given when the item of the PRIASE 2021 checklist was fully reported, whereas a score of '0' was given when an item was not reported; when the item was inadequately or partially reported, a score of '0.5' was given. Based on the overall scores allocated to each manuscript, they were allocated into three categories of reporting quality: low, moderate and high. Associations between study characteristics and reporting quality scores were also analysed. Descriptive statistics and Fisher's exact tests were used to describe the data and determine associations. The probability value of .05 was selected as the level of statistical significance. RESULTS: Based on the overall scores, four (8%) and 46 (92%) of the animal studies evaluated were categorized as 'High' and 'Moderate' reporting quality, respectively. A number of items were adequately reported in all studies related to background (Item 4a), relevance of methods/results (7a) and interpretation of images (11e), whereas only one item related to changes in protocol (6d) was not reported in any. No associations were confirmed between reporting quality scores and number of authors, origin of the corresponding author, journal of publication (endodontic specialty vs. non- specialty), impact factor or year of publication. CONCLUSIONS: Animal studies published in the specialty of endodontics were mostly of 'moderate' quality in terms of the quality of reporting. Adherence to the PRIASE 2021 guidelines will enhance the reporting of animal studies in the expectation that all future publications will be high quality.

The Notch pathway is an evolutionarily preserved signaling pathway involved in a variety of vital cell functions. Additionally, it is one of the key regulators of inflammation, and controls the differentiation and function of different cells. Moreover, it was found to be involved in skeletal development and bone remodeling process. This review provides an overview of the involvement of the Notch signaling pathway in the pathogenesis of alveolar bone resorption in different forms of pathological conditions such as apical periodontitis, periodontal disease, and peri-implantitis. In vitro and in vivo evidence have confirmed the involvement of Notch signaling in alveolar bone homeostasis. Nonetheless, Notch signaling system, along with complex network of different biomolecules are involved in pathological process of bone resorption in apical periodontitis, periodontitis, and peri-implantitis. In this regard, there is a substantial interest to control the activity of this pathway in the treatment of disorders associated with its dysregulation. This review provides knowledge on Notch signaling and outlines its functions in alveolar bone homeostasis and alveolar bone resorption. Further investigations are needed to determine whether inhibition of the Notch signaling pathways might be beneficial and safe as a novel approach in the treatment of these pathological conditions.
ABSTRACT
Observational studies play a critical role in evaluating the prevalence and incidence of conditions or diseases in populations as well as in defining the benefits and potential hazards of health-related interventions. There are currently no reporting guidelines for observational studies in the field of Endodontics. The Preferred Reporting Items for study Designs in Endodontology (PRIDE) team has developed and published new reporting guidelines for observational-based studies called the 'Preferred Reporting items for OBservational studies in Endodontics (PROBE) 2023' guidelines. The PROBE 2023 guidelines were developed exclusively for the speciality of Endodontics by integrating and adapting the 'STrengthening the Reporting of OBservational studies in Epidemiology (STROBE)' checklist and the 'Clinical and Laboratory Images in Publications (CLIP)' principles. The recommendations of the Guidance for Developers of Health Research Reporting Guidelines were adhered to throughout the process of developing the guidelines. The purpose of this document is to serve as a guide for authors by providing an explanation for each of the items in the PROBE 2023 checklist along with relevant examples from the literature. The document also offers advice to authors on how they can address each item in their manuscript before submission to a journal. The PROBE 2023 checklist is freely accessible and downloadable from the PRIDE website (http://pride-endodonticguidelines.org/probe/).

BACKGROUND: The exposed pulp has been the topic of numerous studies, but well-designed and well-executed comparative trials on the outcome and treatment of these teeth have been limited. OBJECTIVES: This study was conducted to answer the following questions: in patients with nontraumatic pulpitis associated with no or nonspontaneous pain in permanent teeth, (i) is direct pulp capping or pulpotomy (partial/full) as effective as selective or stepwise caries removal [Population/participants, Intervention(s), Comparator(s)/control, Outcome(s) (PICO) 1], (ii) is pulpotomy (partial/full) as effective as direct pulp capping (PICO 2) and (iii) is pulpotomy (partial/full) as effective as a pulpectomy (PICO 3), in terms of a combination of patient and clinical reported outcomes, with 'tooth survival' as the most critical outcome? METHODS: A literature search was conducted using Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Central Register of Controlled Trials from inception to November 3rd 2021. Grey literature and contents of the major subject journals were examined. Eligibility criteria followed the PICO questions. Two independent reviewers performed study selection, data extraction and appraisal; disagreements were resolved by a third reviewer. The risk of bias was assessed by the revised Cochrane risk-of-bias tool for randomized trials. RESULTS: Three randomized clinical trials (RCTs) were included in the review. No study fulfilled the criteria to answer PICO 1. There were no significant differences in the reported outcomes between investigated treatments in all included RCTs. None of the included studies reported the most critical outcome 'tooth survival'. A high loss of patients during the follow-up period was observed. DISCUSSION: Although a few studies fulfilled strict eligible criteria, the results of this systematic review clearly highlight a paucity of available evidence. At the present time, clinical decisions cannot be substantiated by direct comparative trials. CONCLUSIONS: Based on limited evidence, this systematic review discovered no significant differences in effectiveness between compared vital pulp treatments in managing nontraumatic pulpitis associated with no or nonspontaneous pain. Further high-quality RCTs are necessary to investigate the effectiveness of direct pulp capping or pulpotomy (partial/full) compared to selective or stepwise caries removal.

BACKGROUND: Pulpitis characterized by spontaneous pain can result in debilitating pain. Dogma has existed to offer only have two treatment options, namely root canal treatment (RCT) or extraction, although pulpotomy has always remained a potential treatment modality. OBJECTIVE: This review aimed to answer the following research question: 'Does pulpotomy (partial or full) (I) result in better patient and clinical reported outcomes (O), compared with RCT (C) in permanent teeth with pulpitis characterized by spontaneous pain (P) evaluated at various time intervals?' (T). METHODS: Two authors independently performed study selection, data extraction and risk of bias assessment. The literature search was conducted in the following electronic databases: Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Central Register of Controlled Trials. English language clinical trials comparing the patient and clinical reported outcomes between RCT and pulpotomy were included. The meta-analysis was performed on a fixed-effect model and the quality of evidence assessed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. RESULTS: Two randomized clinical trials were included. Amongst two trials, one has published four reports at different time points involving the same cohorts. The meta-analysis revealed no difference in postoperative pain (Day 7) between RCT and pulpotomy (OR = 0.99, 95% CI 0.63-1.55, I2 = 0%) and quality of evidence was graded as 'High'. Clinical success was high at year 1, 98% for both interventions, however, decreased over time to 78.1% (pulpotomy) and 75.3% (RCT) at 5 years. DISCUSSION: Pulpotomy is a definitive treatment modality that is as effective as RCT. This could have a significant impact on treatment of such patients affording the advantages of retaining a vital pulp and preventing the need for RCT. CONCLUSION: This review could only include two trials, hence there is insufficient evidence to draw robust conclusions. The clinical data accumulated so far suggests no difference in pain between RCT and pulpotomy at Day 7 postoperatively and a single randomized control trial suggests that the clinical success rate for both treatment modalities is similar long term. There is a need for more well-designed trials by different research groups to develop a stronger evidence base in this area. REGISTRATION: PROSPERO database (CRD42021259744).

BACKGROUND: There is significant controversy surrounding the link between diabetes mellitus and post-operative complications after carotid endarterectomy (CEA). The aim of this study was to identify the possible effects of diabetes on the frequency of post-operative complications after CEA. METHODS: This prospective study was conducted at the Dedinje Clinic for Vascular Surgery, Belgrade. The patients who underwent CEA were divided into two groups: group A (37.7%) included 98 (35.1%) insulin-dependent and 181 (64.9%) insulin-independent diabetic patients, and group B (62.3%) comprised non-diabetic subjects. RESULTS: The pre-operative characteristics were similar, except for a greater prevalence of dyslipidaemia in patients with diabetes. Post-operative cardiac events occurred more often in patients with diabetes (3.6%) than in non-diabetic patients (1.1%) (p = 0.039); post-operative neurological events among patients with diabetes were 3.6% and among non-diabetics, 0.9% (p = 0.009). Peri-operative mortality rate was 2.5% in the diabetic group and 0.9% in the non-diabetic group. The total percentage of post-operative complications was two or more times higher in the diabetic group than the non-diabetic group (8.5 vs 18.3%, p < 0.001). CONCLUSIONS: Diabetes mellitus increased the surgical risk of CEA. Higher rates of mortality and post-operative complications were observed in patients being treated with oral antidiabetics than in those on insulin.

BACKGROUND: Despite numerous studies indicating a high prevalence of herpesviruses in both apical and marginal periodontitis samples, their exact role in the pathogenesis of a periodontal disease is still unclear. OBJECTIVE: This umbrella review aimed to summarize data on herpesviruses detection in marginal periodontitis (MP) and apical periodontitis of endodontic origin (APEO) samples. METHODS: The study protocol has been drafted a priori and registered to the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42020215922). The literature search was conducted using the following electronic databases: Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Database of Systematic Reviews, from inception to October 2020, with no language restrictions. Systematic reviews with or without meta-analysis that evaluated the association between the occurrence of herpesviruses and different forms of periodontal diseases were included. Other types of studies, including narrative reviews, were excluded. Two reviewers independently performed a literature search, data extraction, and quality assessment of included studies. Any disagreements or doubts were resolved by a third reviewer. The quality of the reviews was assessed using the AMSTAR 2 tool (A measurement tool to assess systematic reviews). RESULTS: Six systematic reviews were included in the current review. One was graded as high quality, another one was graded as moderate quality, whereas the other four were graded as critically low-quality reviews. The presence of herpesviruses in subgingival samples was associated with an increased risk of MP, supported by the corresponding meta-analyses. Although the association was strong (OR > 3.0), the confidence intervals were wide, heterogeneity was significant, and studies were of small sample size. In addition, publication bias was detected. Contrary, data from systematic reviews that assessed APEO and herpesviruses did not show any significant associations. CONCLUSIONS: Low-quality studies with high uncertainty suggest a strong association between herpesviruses and MP, but not with APEO.

BACKGROUND: The interaction between heredity and different environmental factors in the modification of apical periodontitis (AP) susceptibility and prediction of its progression remain poorly elucidated. OBJECTIVES: This umbrella review aimed to (i) analyse the available relevant systematic reviews in an attempt to determine the association between genotype and allelic distribution of different single-nucleotide polymorphisms (SNPs) and the development of AP, (ii) report deficiencies and gaps in knowledge in this area and (iii) present recommendations to conduct future clinical studies and systematic reviews. METHODS: A literature search was conducted using Clarivate Analytics' Web of Science, Scopus, PubMed and Cochrane Database of Systematic Reviews, from inception to October 2021, with no language restrictions, including a grey literature search. Systematic reviews with/without meta-analysis evaluating genotype and allelic distribution of different SNPs between adult patients with/ without AP were included. All other type of studies were excluded. The methodological quality was assessed using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2 tool. Two independent reviewers were involved in study selection, data extraction and appraising the included reviews; disagreements were resolved by a third reviewer. RESULTS: The current study includes five systematic reviews. Three reviews performed meta-analysis. Three reviews were graded by AMSTAR 2 as 'critically low' quality, whereas the other two were graded as 'low' and 'moderate' quality. Two reviews indicated that carriers of specific genotypes and alleles of tumour necrosis factor-alpha (TNF-α) -308 G > A and interleukin 1-beta (IL-1ß) + 3954 C/T gene polymorphisms are more susceptible to an acute and persistent form of AP. However, high heterogeneity was observed. DISCUSSION: The statistical heterogeneity within included systematic reviews was a consequence of clinical and methodological diversity amongst primary studies. Although some of the included reviews suggested that carriers of specific genotype and/or allele of TNF-α -308 G > A and IL-1ß + 3954 C/T SNPs are more susceptible to AP, their conclusions should be interpreted with caution. CONCLUSIONS: No candidate genes could be identified as a definitive genetic risk or protective factor for the development and progression of AP, and further high-quality genome-wide association studies are warranted.

The aim of the present systematic review was to critically analyse the relationship between tumour suppressor genes (TSGs) promoter methylation, a potent mechanism of gene silencing, and the development of salivary gland tumours, as well as the possible effect on clinical/histological characteristics. Review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (registration ID CRD42020218511). A comprehensive search of Web of Science, Scopus, PubMed, and Cochrane Central Register of Controlled Trials was performed utilizing relevant key terms, supplemented by a search of grey literature. Newcastle-Ottawa Quality Assessment Scale (NOQAS) was used for the quality assessment of included studies. Sixteen cross-sectional and 12 case-control studies were included in the review, predominantly dealing with methylation in TSGs related to DNA repair, cell cycle, and cell growth regulation and differentiation. Quantitative synthesis could be performed on P16 (inhibitor of cyclin-dependent kinase 4a), RASSF1A (Ras association domain family 1 isoform A) and MGMT (O6-methylguanine DNA methyltransferase) genes only. It showed that P16 and RASSF1A genes were more frequently methylated in salivary gland tumours compared to controls (P = .0002 and P < .0001, respectively), while no significant difference was observed for MGMT. Additionally, P16 did not appear to be related to malignant transformation of pleomorphic adenomas (P = .330). In conclusion, TSG methylation is involved in salivary gland tumour pathogenesis and several genes might play a considerable role. Further studies are needed for a better understanding of complex epigenetic deregulation during salivary gland tumour development and progression.

AIM: To identify the top 100 most-cited case reports and case series published in Endodontic journals and to analyse their bibliometric characteristics. METHODOLOGY: The Clarivate Analytics' Web of Science (WoS), Scopus and PubMed databases were used to identify the top 100 most-cited case reports and case series in Endodontic journals. Complete bibliographic records of the selected case reports and case series were exported in plain text or BibTeX format and imported into the R environment for statistical computing and graphics. The following parameters were then analysed: names and affiliations of the authors, title, year of publication, journal of publication, first author, corresponding author, literature cited within reports, language, citation counts, impact factor of the journal, keywords, Keywords Plus and research topic. RESULTS: In total, 88 case reports and 12 case series published in English between 1977 and 2016 were identified as the most-cited reports in the field of Endodontics. The terms "case report(s)" or "case series" were not included in the title of 57 articles. The number of authors per report ranged from one to seven, with the average number of co-authors per report being 3.14. The most-cited author was M Trope (University of Pennsylvania, USA). The University of Washington and Private Practice, Cetraro, Italy, were the most productive institutions. The country whose case reports received the largest total number of citations was the United States. The largest number of the most-cited reports appeared in 2002, 2004 and 2007 (n = 7, respectively). According to the WoS database, the total number of citations ranged from 42 to 453, with the average number of citations per report being 79.97. The majority of the top 100 most-cited articles were published in the Journal of Endodontics and the International Endodontic Journal. The most frequently used author keywords were revascularization and mineral trioxide aggregate. The majority of the case reports and case series dealt with topics related to pulp regeneration. CONCLUSION: This bibliometric study provides a comprehensive overview on the progress, trends and current directions in clinical practice within the field of Endodontics.

OBJECTIVES: The aim of this systematic review was to critically analyze available data on gene polymorphisms in odontogenic keratocysts (OKC) and ameloblastomas, including their possible relationship with clinical and histological features of these lesions. MATERIALS AND METHODS: A comprehensive search of Web of Science Scopus, PubMed, Cochrane Central Register of Controlled Trials and EMBASE was conducted using relevant key terms and supplemented by a gray literature search. Quality assessment of included studies was performed using criteria from the Strengthening the Reporting of Genetic Association (STREGA) statement. RESULTS: Ten studies were included in the final review. Survivin -31G/C, interleukin IL-1α -889 C/T, p53 codon 72 G/C, tumor necrosis factor TNF-α (-308G>A) and its receptor TNF-R1 (36A>G), glioma-associated oncogene homolog 1 rs2228224 and matrix metalloproteinase 2 rs243865 gene polymorphisms were reported to be associated with OKC. For ameloblastomas, p53 codon 72 G/C, X-ray repair cross-complementing protein 1-codons 194 and 399 and matrix metalloproteinase 9 rs3918242 gene polymorphisms were identified as risk factors. It was not possible to establish a relationship between specific polymorphisms and clinical and histological features of investigated lesions. CONCLUSIONS: Several gene polymorphisms might be considered as a risk factor for the development of these lesions. Future studies should investigate whether these polymorphisms might be used to identify patients with increased risk of recurrence or aggressive disease.

OBJECTIVES: The rapid production of a large volume of literature during the early phase of the COVID-19 outbreak created a substantial burden for clinicians and scientists. Therefore, this manuscript aims to identify and describe the scientific literature addressing COVID-19 from a dental research perspective, in terms of the manuscript origin, research domain, study type, and level of evidence (LoE). MATERIALS AND METHODS: Data were retrieved from Web of Science, Scopus, and PubMed. A descriptive analysis of bibliographic data, collaboration network, and keyword co-occurrence analysis were performed. Articles were further classified according to the field of interest, main research question, type of study, and LoE. RESULTS: The present study identified 296 dental scientific COVID-19 original papers, published in 89 journals, and co-authored by 1331 individuals affiliated with 429 institutions from 53 countries. Although 81.4% were single-country papers, extensive collaboration among the institutions of single countries (Italian, British, and Brazilian institutions) was observed. The main research areas were as follows: the potential use of saliva and other oral fluids as promising samples for COVID-19 testing, dental education, and guidelines for the prevention of COVID-19 transmission in dental practice. The majority of articles were narrative reviews, cross-sectional studies, and short communications. The overall LoE in the analyzed dental literature was low, with only two systematic reviews with the highest LoE I. CONCLUSION: The dental literature on the COVID-19 pandemic does not provide data relevant to the evidence-based decision-making process. Future studies with a high LoE are essential to gain precise knowledge on COVID-19 infection within the various fields of Dentistry. CLINICAL RELEVANCE: The published dental literature on COVID-19 consists principally of articles with a low level of scientific evidence which do not provide sufficient reliable high-quality evidence that is essential for decision making in clinical dental practice.
