Meta-Analysis Review
: Endodontic microsurgery (EMS) aims to eradicate the sources of infection once the apical root resection removes most of the infected anatomical structures and repairs potential procedural errors in the apical region. An endodontic-periodontal lesion yields a pathological communication between the pulp and the periodontium. The purpose of this systematic review and meta-analysis is to evaluate the impact of periodontal attachment loss on the outcome of teeth submitted to EMS. : PRISMA guidelines were followed. An electronic search was performed in EBSCOhost, Embase and PubMed databases with the following search key: ("endodontic microsurgery" AND "outcome"). No filters were used concerning the year of publication or language. Only randomized clinical trials, prospective and retrospective clinical studies in humans, with a minimum one-year follow-up, defined clinical and radiographic outcome criteria and estimable success rate for endodontic-periodontal lesion were included. Statistical analysis was performed using OpenMeta[Analyst] software. : Of a total of 113 articles, 34 were selected for full-text reading after duplicates deletion and title and abstract analysis. Thirteen and six studies were included in the systematic review and meta-analysis, respectively. A total of 2775 pooled teeth were submitted to EMS, of which 492 teeth and 4 roots had periodontal involvement. According to the qualitative analysis, success rates of the endodontic-periodontal group ranged from 67.6% to 88.2%. Meta-analysis revealed that the absence of periodontal attachment loss was predictive of a higher likelihood of success with an odds ratio of 3.14. : Periodontal attachment loss presents a risk factor for EMS outcome. Although endodontic-periodontal lesions were associated with lower success rates considering a 1 to 10 years follow-up period, long-term successful prognosis following EMS has been reported, therefore presenting a fully valid and viable therapeutic option for the management of this type of lesions.

Review
Whether "periodontal disease" can be considered as an independent risk factor for head and neck cancer (HNC) remains controversial. The aim of the current meta-analysis was to quantitatively assess this relationship in order to determine whether this represents a true risk factor, with implications for cancer prevention and management. PubMed, Scopus, and Embase databases were systematically searched. Selective studies were reviewed, and meta-analysis was performed to estimate the pooled odds ratio (OR) with 95% confidence intervals (CIs) on eligible studies using a random effects model. In total, 21 eligible observational studies (4 cohorts and 17 case-controls) were identified for qualitative synthesis after a review of 1051 articles. Significant heterogeneity could be identified in measures utilized for reporting of periodontal disease. Meta-analysis performed on nine studies that employed objective measures for reporting periodontal disease demonstrated a significant association between periodontal disease and HNC [OR 3.17, 95% CI, 1.78-5.64]. A diseased periodontium represents an independent risk marker, and a putative risk factor, for HNC. Prospective studies with standardized measures of periodontal disease severity and extent, integrated with microbiological and host susceptibility facets, are needed to elucidate the mechanisms of this positive association and whether treatment of the former influences the incidence and outcomes for HNC.

Review
INTRODUCTION
This purpose of this systematic review was to evaluate the literature and update our current understanding of the impact of present cancer therapies on the dental apparatus (teeth and periodontium) since the 1989 NIH Development Consensus Conference on the Oral Complications of Cancer Therapies.
REVIEW METHOD
A systematic literature search was conducted with assistance from a research librarian in the databases MEDLINE/PubMed and EMBASE for articles published between 1 January 1990 and 31 December 2008. Each study was independently assessed by two reviewers. Taking into account predetermined quality measures, a weighted prevalence was calculated for the prevalence of dental caries, severe gingival disease, and dental infection. Data on DMFT/dmft, DMFS/dmfs, plaque, and gingival indexes were also gathered. The level of evidence, recommendation, and guideline (if possible) were given for published preventive and management strategies.
RESULTS
Sixty-four published papers between 1990 and 2008 were reviewed. The weighted overall prevalence of dental caries was 28.1%. The overall DMFT for patients who were post-antineoplastic therapy was 9.19 (SD, 7.98; n = 457). The overall plaque index for patients who were post-antineoplastic therapy was 1.38 (SD, 0.25; n = 189). The GI for patients who were post-chemotherapy was 1.02 (SD, 0.15; n = 162). The weighted prevalence of dental infections/abscess during chemotherapy was reported in three studies and was 5.8%.
CONCLUSIONS
Patients who were post-radiotherapy had the highest DMFT. The use of fluoride products and chlorhexidine rinses are beneficial in patients who are post-radiotherapy. There continues to be lack of clinical studies on the extent and severity of dental disease that are associated with infectious complications during cancer therapy.

Comparing the Effectiveness of Ultrasonic Instruments Over Manual Instruments for Scaling and Root Planing in Patients With Chronic Periodontitis: A Systematic Review and Meta-Analysis.
Periodontal disease is a chronic, complex, and infectious condition that affects the periodontium. Its progressive form can be identified by the loss and destruction of the periodontal ligament and the alveolar bone, respectively. Periodontal disease, one of the most prevalent oral cavity diseases, is responsible for tooth loss. Scaling and root planing (SCRP) is a standard, non-invasive periodontal therapy for treating patients with periodontitis. However, there have also been connections to disputed results. According to reports, SCRP alone is ineffective in removing pathogenic microorganisms and their by-products from periodontal pockets. In light of this, our current study aims to determine if using manual or ultrasonic instruments for SCRP in patients with a clinical diagnosis of chronic periodontitis is preferable. This systematic evaluation compares the effectiveness of manual and ultrasonic devices for SCRP, a line of therapy for individuals with a clinical diagnosis of chronic periodontitis. The databases searched were Prospero, PubMed, MEDLINE, CENTRAL, ClinicalTrials.gov, and Cochrane Library, which exclusively included English-language papers. The articles were also manually searched for any information missed during the search process.

Meta-Analysis Review
BACKGROUND
Implants may be placed penetrating the oral mucosa (1-stage procedure) or can be completely buried under the oral mucosa (2-stage procedure) during the healing phase of the bone at the implant surface. With a 2-stage procedure the risk of having unwanted loading onto the implants is minimized, but a second minor surgical intervention is needed to connect the healing abutments and more time is needed prior to start the prosthetic phase because of the wound-healing period required in relation to the second surgical intervention.
OBJECTIVES
To evaluate whether a 1-stage implant placement procedure is as effective as a 2-stage procedure.
SEARCH METHODS
The Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE and EMBASE were searched. Handsearching included several dental journals. Authors of all identified trials, an Internet discussion group and 55 dental implant manufacturers were contacted to find unpublished randomised controlled trials (RCTs). The last electronic search was conducted on 21 January 2009.
SELECTION CRITERIA
All RCTs of osseointegrated dental implants comparing the same dental implants placed according to 1- versus 2-stage procedures with a minimum follow up of 6 months after loading. Outcome measures were: prosthesis failures, implant failures, marginal bone level changes on intraoral radiographs, patient preference including aesthetics, aesthetics evaluated by dentists, and complications.
DATA COLLECTION AND ANALYSIS
Screening of eligible studies, assessment of the methodological quality of the trials and data extraction were conducted in duplicate and independently by two review authors. Authors were contacted for missing information. Results were expressed as random-effects models using mean differences for continuous outcomes and risk ratios for dichotomous outcomes with 95% confidence intervals.
MAIN RESULTS
Five RCTs were identified and included reporting data on 239 patients in total. On a patient, rather than per implant basis, the meta-analyses showed no statistically significant differences for prosthesis and implant failures, though trends, especially in fully edentulous patients, favoured 2-stage (submerged) implants.
AUTHORS' CONCLUSIONS
The number of patients included in the trials was too small to draw definitive conclusions. The 1-stage approach might be preferable in partially edentulous patients since it avoids one surgical intervention and shortens treatment times, while a 2-stage submerged approach could be indicated when an implant has not obtained an optimal primary stability or when barriers are used for guided tissue regeneration, or when it is expected that removable temporary prostheses could transmit excessive forces on the penetrating abutments especially in fully edentulous patients.

Clinical Oral Investigations Mar 2024To investigate the oral manifestations in women of reproductive age using hormonal contraceptive methods. (Review)
Review
OBJECTIVES
To investigate the oral manifestations in women of reproductive age using hormonal contraceptive methods.
MATERIALS AND METHODS
This review is based on the PRISMA statement. A literature search incorporated observational studies from the last 21 years. An investigative question was formulated using the PICO model, studies were selected, and a quality analysis was performed using the modified STROBE guidelines. A bibliometric analysis was performed, and the data were examined.
RESULTS
Thirteen articles were included, with the majority evaluating periodontal status. Others analyzed factors such as the presence of alveolar osteitis, oral candidiasis, and salivary microbiome dysbiosis. Ten articles were deemed to have a low risk of bias.
CONCLUSIONS
Hormonal contraceptives may increase the risk of alveolar osteitis following tooth extraction and increase the presence of the Candida species in the oral cavity. They also affect the periodontium, such as the frequent development of gingivitis, but do not lead to changes in the salivary microbiome.
CLINICAL RELEVANCE
The increasing number of women using hormonal contraceptives and the knowledge that these contraceptives can produce oral cavity alterations underscore the need to evaluate the oral manifestations found in these women.

Meta-Analysis Review
BACKGROUND
The aim of this systematic review is to evaluate the long term (≥ 2 years) effect of four surgical and non-surgical therapies in treating periodontal disease.
METHODS
An electronic search of four databases and a hand search of peer-reviewed journals for relevant articles were conducted. Prospective human controlled clinical trials were included that compared surgical therapy to non-surgical therapy in ≥ 10 patients diagnosed with chronic periodontitis with a follow-up period of ≥ 2 years and that reported change in probing depth (PD) and clinical attachment level (CAL) after the therapy. Random effect meta-analysis was performed to compare the outcome of surgical and non-surgical therapy in shallow, moderate, and deep PD.
RESULTS
Eight human prospective clinical trials were included. In 1- to 3-mm PD, scaling and root planing (SRP), modified Widman flap (MWF), and osseous surgery (OS) resulted in 23.2%, 39.4%, and 61.39% CAL loss, respectively; SRP, MWF, and OS resulted in increased mean PD of 2.5%, 3.3%, and 6.3%, respectively. In 4- to 6-mm PD, SRP, MWF, and OS resulted in 8.4%, 6.5%, and 5.22% CAL gain, respectively; SRP, MWF, and OS resulted in 18.7%, 25.4%, and 30.8% PD reduction, respectively. In PD ≥ 7 mm, SRP, MWF, and OS resulted in 9.8%, 14.2%, and 9.38% CAL gain, respectively; SRP, MWF, and OS resulted in mean PD reduction of 21.6%, 33.1%, and 42.8%, respectively.
CONCLUSIONS
Surgical therapy had significantly more CAL loss than non-surgical therapy in shallow PD. In moderate PD, MWF had significantly more PD reduction than SRP, and there was significantly less CAL gain with surgical therapy. In deep PD, OS had significantly higher PD reduction than SRP.

Meta-Analysis Review
OBJECTIVES
To assess the Candida species occurrence rate and concentration in periodontal pockets in chronic periodontitis (CP) by meta-analysis.
MATERIALS AND METHODS
A search was performed of articles published between January 1, 2010, and October 1, 2020, in English and in Russian, in the electronic databases MEDLINE-PubMed, Google Scholar, The Cochrane Library, ClinicalTrials.gov, Research Gate, eLIBRARY, and Cyberleninka (PROSPEROCRD42021234831). The odds ratio (OR), standardized mean difference (SMD), and 95% confidence interval (CI) were calculated using Review Manager 5.4.1 to compare the risk of CP when Candida spp. were detected in the gingival sulcus or periodontal pocket and to compare Candida spp. density counts in patients with CP and periodontally healthy patients.
RESULTS
Twenty-six studies were included in the systematic review and 11 were included in the meta-analysis. The results showed that Candida spp. may increase the chance of CP development by 1.76 times (OR = 1.76; 95% CI = 1.04-2.99; Z = 2.10; p = .04; I = 61%). More Candida spp. were found in patients with CP than in periodontally healthy patients (SMD = 1.58; 95% CI = 0.15-3.02; p = .03; I = 98%). No data were found relating to the statistically significant influence of Candida glabrata, Candida krusei and Candida tropicalis on CP development.
CONCLUSION
We found that Candida albicans insignificantly increased the risk of CP development but, due to the heterogeneity of the included studies, further research is necessary to determine the exact role of Candida spp. in the development and course of the inflammatory periodontal diseases.

Review
The aim of this article was to examine the research articles regarding biological and mechanical properties of cryopreserved teeth for potential use in tooth transplantation. A systematic review of literatures was performed by Pubmed searching with assigned key words from January 1, 1990 to June 8, 2009. All articles were examined for inclusion criteria. Secondary search was conducted by hand-search through references of included articles from primary search. A total of 24 articles were obtained from both primary and secondary search and used as fundamental articles in this review. Periodontal ligament tissues of cryopreserved teeth were able to maintain their biological properties resulted in a satisfactory healing of periodontium. Dental pulp tissues, however, may be compromised by limitation of permeability of cryopreservative agent into pulp cavity. Therefore, an endodontic treatment of transplanted cryopreserved teeth was recommended. Cryopreserved teeth had comparable mechanical properties to those of normal teeth. Importantly, the success of cryopreserved tooth transplantation treatment in orthodontic patients was reported. The cryopreserved teeth for tooth banking have a potential clinical application for treatment of missing teeth. Case selection, however, is critical for treatment success. More studies and data regarding masticatory function and periodontal healing of transplanted cryopreserved teeth are needed.

Meta-Analysis
Comparative analysis of xenogeneic collagen matrix and autogenous subepithelial connective tissue graft to increase soft tissue volume around dental implants: a systematic review and meta-analysis.
OBJECTIVE
The gold standard for a soft tissue augmentation around implants is a subepithelial connective tissue graft (CTG), but the xenogeneic collagen matrices (XCM) started to be used as an alternative. This systematic review aimed to assess the effectiveness XCM in comparison to CTG for the increasing the thickness of the soft tissue around implants.
DATA
All studies included at least two parallel groups comparing the use of CTG and XCM with a minimum follow-up of 3 months. As the primary outcome, the amount of soft tissue thickness gain after soft tissue augmentation with XCM or CTG was assessed. Secondary outcomes were clinical and patient-related outcomes; evaluation of aesthetic outcomes, patient-reported outcomes measures (PROMs) and complications. Eligible studies were selected based on the inclusion criteria. Meta-analysis was applied whenever possible. The quality of the evidence of studies including in meta-analysis was assessed using the GRADE approach.
SOURCE
A systematic literature search up to January 2022 was conducted using the following electronic databases: PubMed (MEDLINE), Scopus, Cochrane Library, LILACS, eLIBRARY.RU. Unpublished researches, the gray literature, nonprofit reports, government studies and other materials were reviewed electronically using an EASY search. An additional manual search was carried out in November 2022.
STUDY SELECTION
Of the 1376 articles from the initial search, 8 randomized controlled trials (RCTs) (306 patients and 325 implants) were included in this systematic review, and 7 studies were part of the meta-analysis. Meta-analysis revealed that XCM is less effective than the CTG in increasing soft tissue thickness around dental implants. However, XCM also provides soft tissue thickness gain and can be recommended for use in various clinical situations.
CLINICAL SIGNIFICANCE
Previous systematic reviews and meta-analyses have shown that autologous grafts are more effective than collagen matrices in increasing soft tissue thickness, however, the latter can be used as an alternative. Studies included in previous systematic reviews varied in design, which could lead to limitations. The present systematic review and meta-analysis includes for the first time only randomized controlled clinical trials with collagen matrix of xenogeneic origin in the test group. Tight eligibility criteria were established, and the main parameter studied was soft tissue thickness. It was found that xenogeneic collagen matrix is effective for increasing soft tissue thickness around dental implants, however, the results obtained using an autogenous connective tissue graft are superior.
