[PMID: 38877442 PMCID: PMC11177403 DOI: 10.1186/s12903-024-04433-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 06/03/2024] [Indexed: 06/16/2024] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of mortality in the world. Patients with periodontitis have a higher risk of CVD, although a causal relationship between these conditions remains unclear. Non-surgical periodontal therapy (NSPT) is able to control inflammation at local and systemic levels. This study aimed to analyze the effect of NSPT on CVD risk markers. METHODS Four electronic databases were searched from their inception to April 1, 2023, to identify and select articles without any language restrictions. Eleven CVD-related markers (e.g., C-reactive protein [CRP], Interleukin-6 [IL-6]) were selected. Meta-analyses were performed using random and fixed effect models. The differences were expressed as weighted mean differences (WMD) and 95% confidence interval (95% CI). RESULTS From 1353 studies, twenty-one randomized controlled clinical trials were included in the meta-analysis. Results showed a significant decrease in CRP, IL-6, and systolic blood pressure (SBP) after NSPT. CONCLUSION Moderate certainty evidence shows that NSPT has a positive effect on the reduction of IL-6 and SBP in patients with periodontitis, while low certainty evidence shows that NSPT is effective for reduction of CRP. Moderate certainty evidence showed that NSPT did not show a positive effect on low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC) and triglycerides (TG), and low certainty evidence showed that NSPT did not show a positive effect on Interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α), diastolic blood pressure (DBP), and flow-mediated dilatation (FMD). PROTOCOL REGISTRATION The protocol was registered in the PROSPERO (International Prospective Register of Systematic Reviews), number CRD42022377565.

Abstract
Background The link between dental, infective and obstructive cardiovascular diseases is debatable. Aim To systematically review the literature to assess the association between dental conditions and development of cardiovascular disease. Methods The systematic review was conducted following the PRISMA guidelines using PubMed (Medline), Web of Science, Scopus, EMBASE and SciELO. Results Out of 6680 records, 82 articles were eligible for inclusion after reviewing titles and abstracts. No association between dental disease and cardiovascular disease has been observed in 10 studies while a potential link has been suggested by the remaining trials. Tooth loss and periodontitis are the main evaluated oral conditions while coronary artery disease, stroke, atherosclerosis and myocardial infarction represent the major cardiovascular events. The interaction between these two clinical entities is based on direct mechanism mediated by systemic inflammatory response, leakage of cytokines and endothelial cells invasion by oral pathogens and indirect mechanism mediated by common risk factors or confounders. Conclusions It seems that tooth loss, periodontitis and poor oral hygiene increase the risk of atherosclerotic cardiovascular events, and subsequently oral health care professionals could contribute to public health cardiovascular control efforts.

Abstract
BACKGROUND There may be an association between periodontitis and cardiovascular disease (CVD); however, the evidence so far has been uncertain about whether periodontal therapy can help prevent CVD in people diagnosed with chronic periodontitis. This is the third update of a review originally published in 2014, and most recently updated in 2019. Although there is a new multidimensional staging and grading system for periodontitis, we have retained the label 'chronic periodontitis' in this version of the review since available studies are based on the previous classification system. OBJECTIVES To investigate the effects of periodontal therapy for primary or secondary prevention of CVD in people with chronic periodontitis. SEARCH METHODS An information specialist searched five bibliographic databases up to 17 November 2021 and additional search methods were used to identify published, unpublished, and ongoing studies. We also searched the Chinese BioMedical Literature Database, the China National Knowledge Infrastructure, the VIP database, and Sciencepaper Online to March 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared active periodontal therapy to no periodontal treatment or a different periodontal treatment. We included studies of participants with a diagnosis of chronic periodontitis, either with CVD (secondary prevention studies) or without CVD (primary prevention studies). DATA COLLECTION AND ANALYSIS Two review authors carried out the study identification, data extraction, and 'Risk of bias' assessment independently and in duplicate. They resolved any discrepancies by discussion, or with a third review author. We adopted a formal pilot-tested data extraction form, and used the Cochrane tool to assess the risk of bias in the studies. We used GRADE criteria to assess the certainty of the evidence. MAIN RESULTS There are no new completed RCTs on this topic since we published our last update in 2019. We included two RCTs in the review. One study focused on the primary prevention of CVD, and the other addressed secondary prevention. We evaluated both as being at high risk of bias. Our primary outcomes of interest were death (all-cause and CVD-related) and all cardiovascular events, measured at one-year follow-up or longer. For primary prevention of CVD in participants with periodontitis and metabolic syndrome, one study (165 participants) provided very low-certainty evidence. There was only one death in the study; we were unable to determine whether scaling and root planning plus amoxicillin and metronidazole could reduce incidence of all-cause death (Peto odds ratio (OR) 7.48, 95% confidence interval (CI) 0.15 to 376.98), or all CVD-related death (Peto OR 7.48, 95% CI 0.15 to 376.98). We could not exclude the possibility that scaling and root planning plus amoxicillin and metronidazole could increase cardiovascular events (Peto OR 7.77, 95% CI 1.07 to 56.1) compared with supragingival scaling measured at 12-month follow-up. For secondary prevention of CVD, one pilot study randomised 303 participants to receive scaling and root planning plus oral hygiene instruction (periodontal treatment) or oral hygiene instruction plus a copy of radiographs and recommendation to follow-up with a dentist (community care). As cardiovascular events had been measured for different time periods of between 6 and 25 months, and only 37 participants were available with at least one-year follow-up, we did not consider the data to be sufficiently robust for inclusion in this review. The study did not evaluate all-cause death and all CVD-related death. We are unable to draw any conclusions about the effects of periodontal therapy on secondary prevention of CVD. AUTHORS' CONCLUSIONS For primary prevention of cardiovascular disease (CVD) in people diagnosed with periodontitis and metabolic syndrome, very low-certainty evidence was inconclusive about the effects of scaling and root planning plus antibiotics compared to supragingival scaling. There is no reliable evidence available regarding secondary prevention of CVD in people diagnosed with chronic periodontitis and CVD. Further trials are needed to reach conclusions about whether treatment for periodontal disease can help prevent occurrence or recurrence of CVD.

Abstract
Abstract
Background and objectives
Aboriginal Australians and Torres Strait Islanders (hereafter respectfully referred to as Indigenous Australians) experience a high burden of chronic non-communicable diseases (NCDs). Increased NCD risk is linked to oral diseases mediated by the oral microbiota, a microbial community influenced by both vertical transmission and lifestyle factors. As an initial step towards understanding the oral microbiota as a factor in Indigenous health, we present the first investigation of oral microbiota in Indigenous Australian adults.
Methodology
Dental calculus samples from Indigenous Australians with periodontal disease (PD; n = 13) and non-Indigenous individuals both with (n = 19) and without PD (n = 20) were characterized using 16S ribosomal RNA gene amplicon sequencing. Alpha and beta diversity, differentially abundant microbial taxa and taxa unique to different participant groups were analysed using QIIME2.
Results
Samples from Indigenous Australians were more phylogenetically diverse (Kruskal–Wallis H = 19.86, P = 8.3 × 10−6), differed significantly in composition from non-Indigenous samples (PERMANOVA pseudo-F = 10.42, P = 0.001) and contained a relatively high proportion of unique taxa not previously reported in the human oral microbiota (e.g. Endomicrobia). These patterns were robust to stratification by PD status. Oral microbiota diversity and composition also differed between Indigenous individuals living in different geographic regions.
Conclusions and implications
Indigenous Australians may harbour unique oral microbiota shaped by their long relationships with Country (ancestral homelands). Our findings have implications for understanding the origins of oral and systemic NCDs and for the inclusion of Indigenous peoples in microbiota research, highlighting the microbiota as a novel field of enquiry to improve Indigenous health.

Abstract
BACKGROUND An association has been hypothesized between periodontitis and hypertension. Periodontal therapy is believed to reduce systemic inflammatory mediators and increase endothelial function, thus having the potential to prevent and treat hypertension. OBJECTIVES To assess the effect and safety of different periodontal treatment modalities on blood pressure (BP) in people with chronic periodontitis. SEARCH METHODS The Cochrane Hypertension Information Specialist searched for randomized controlled trials (RCTs) up to November 2020 in the Cochrane Hypertension Specialised Register, CENTRAL, MEDLINE, Embase, seven other databases, and two clinical trials registries. We contacted the authors of relevant papers regarding further published and unpublished work. SELECTION CRITERIA RCTs and quasi-RCTs aiming to detect the effect of periodontal treatment on BP were eligible. Participants should have been diagnosed with chronic periodontitis and hypertension (or no hypertension if the study explored the preventive effect of periodontal treatment). Participants in the intervention group should have undergone subgingival scaling and root planing (SRP) and any other type of periodontal treatments, compared with either no periodontal treatment or alternative periodontal treatment in the control group. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane for study identification, data extraction, and risk of bias assessment. We used a formal pilot-tested data extraction form for data extraction, and the Cochrane risk of bias tool for risk of bias assessment. We planned the meta-analysis, test for heterogeneity, sensitivity analysis, and subgroup analysis. We assessed the certainty of evidence using GRADE. The primary outcome was change in systolic BP (SBP) and diastolic BP (DBP). MAIN RESULTS We included eight RCTs. Five had low risk of bias, one had unclear risk of bias, and two had high risk of bias. Four trials compared periodontal treatment with no treatment. We found no evidence of a difference in the short-term change of SBP and DBP for people diagnosed with periodontitis and other cardiovascular diseases except hypertension (very low-certainty evidence). We found no evidence of a difference in long-term changes in SBP (mean difference [MD] -2.25 mmHg, 95% confidence interval [CI] -9.41 to 4.92; P = 0.54; studies = 2, participants = 108; low-certainty evidence) and DBP (MD -2.55 mmHg, 95% CI -6.90 to 1.80; P = 0.25; studies = 2, participants = 103; low-certainty evidence). Concerning people diagnosed with periodontitis, in the short term, two studies of low certainty reported no changes in SBP (MD -0.14 mmHg, 95% CI -4.05 to 3.77; P = 0.94; participants = 294) and DBP (MD -0.15 mmHg, 95% CI -2.47 to 2.17; P = 0.90; participants = 294), and we found no evidence of a difference in SBP and DBP over a long period based on low certainty of evidence. Three studies compared intensive periodontal treatment with supra-gingival scaling. We found no evidence of a difference in changes in SBP and DBP for any length of time in people diagnosed with periodontitis (very low-certainty evidence). In people diagnosed with periodontitis and hypertension, we found one study reporting a significant reduction in the short term in SBP (MD -11.20 mmHg, 95% CI -15.40 to -7.00; P < 0.001; participants = 101; moderate-certainty evidence) and DBP (MD -8.40 mmHg, 95% CI -12.19 to -4.61; P < 0.0001; participants = 101; moderate-certainty evidence). AUTHORS' CONCLUSIONS We found no evidence of a difference of an impact of periodontal treatments on BP in most comparisons assessed in this review, and given the low certainty of evidence and the lack of relevant studies we could not draw conclusions about the effect of periodontal treatment on BP in people with chronic periodontitis. We found only one study suggesting that periodontal treatment may reduce SBP and DBP over a short period in people with hypertension and chronic periodontitis, but the certainty of evidence was moderate.

Abstract
Aboriginal and Torres Strait Islander Australians (Indigenous Australians) suffer some of the highest rates of chronic kidney disease (CKD) in the world. Among Indigenous Australians in remote areas of the Northern Territory, prevalence rates for renal replacement therapy (RRT) are up to 30 times higher than national prevalence. Anemia among patients with CKD is a common complication. Iron deficiency is one of the major causes. Iron deficiency is also one of the key causes of poor response to the mainstay of anemia therapy with erythropoiesis-stimulating agents (ESAs). Therefore, the effective management of anemia in people with CKD is largely dependent on effective identification and correction of iron deficiency. The current identification of iron deficiency in routine clinical practice is dependent on 2 surrogate markers of iron status: serum ferritin concentration and transferrin saturation (TSAT). However, questions exist regarding the use of serum ferritin concentration in people with CKD because it is an acute-phase reactant that can be raised in the context of acute and chronic inflammation. Serum ferritin concentration among Indigenous Australians receiving RRT is often markedly elevated and falls outside reference ranges within most national and international guidelines for iron therapy for people with CKD. This review explores published data on the challenges of managing anemia in Indigenous people with CKD and the need for future research on the efficacy and safety of treatment of anemia of CKD in patients with high ferritin and evidence iron deficiency.

Abstract
BACKGROUND There is an association between chronic periodontitis and cardiovascular disease (CVD). However, it is not known whether periodontal therapy could prevent or manage CVD in patients with chronic periodontitis. OBJECTIVES The objective of this systematic review was to investigate the effects of periodontal therapy in preventing the occurrence of, and management or recurrence of, CVD in patients with chronic periodontitis. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 31 August 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2017, Issue 7), MEDLINE Ovid (1946 to 31 August 2017), Embase Ovid (1980 to 31 August 2017) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL EBSCO) (1937 to 31 August 2017) . The US National Institutes of Health Trials Registry (ClinicalTrials.gov), the World Health Organization International Clinical Trials Registry Platform and Open Grey were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases.We also searched the Chinese BioMedical Literature Database (1978 to 27 August 2017), the China National Knowledge Infrastructure (1994 to 27 August 2017), the VIP database (1989 to 27 August 2017) and Sciencepaper Online (2003 to 27 August 2017). SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs were considered eligible. Studies were selected if they included patients with a diagnosis of chronic periodontitis and previous CVD (secondary prevention studies) or no CVD (primary prevention studies); patients in the intervention group received active periodontal therapy compared to maintenance therapy, no periodontal treatment or another kind of periodontal treatment in the control group. DATA COLLECTION AND ANALYSIS Two review authors carried out the study identification, data extraction and risk of bias assessment independently and in duplicate. Any discrepancies between the two authors were resolved by discussion or with a third review author. A formal pilot-tested data extraction form was adopted for the data extraction, and the Cochrane tool for risk of bias assessment was used for the critical appraisal of the literature. MAIN RESULTS No studies were identified that assessed primary prevention of CVD in people with periodontitis. One study involving 303 participants with ≥ 50% blockage of one coronary artery or a coronary event within three years, but not the three months prior, was included. The study was at high risk of bias due to deviation from the protocol treatment allocation and lack of follow-up data. The trial compared scaling and root planing (SRP) with community care for a follow-up period of six to 25 months. No data on deaths (all-cause or CVD-related) were reported. There was insufficient evidence to determine the effect of SRP and community care in reducing the risk of CVD recurrence in patients with chronic periodontitis (risk ratio (RR) 0.72; 95% confidence interval (CI) 0.23 to 2.22; very low quality evidence). The effects of SRP compared with community care on high-sensitivity C-reactive protein (hs-CRP) (mean difference (MD) 0.62; -1.45 to 2.69), the number of patients with high hs-CRP (RR 0.77; 95% CI 0.32 to 1.85) and adverse events (RR 9.06; 95% CI 0.49 to 166.82) were also not statistically significant. The study did not assess modifiable cardiovascular risk factors, other blood test results, heart function parameters or revascularisation procedures. AUTHORS' CONCLUSIONS We found very low quality evidence that was insufficient to support or refute whether periodontal therapy can prevent the recurrence of CVD in the long term in patients with chronic periodontitis. No evidence on primary prevention was found.

Abstract
OBJECTIVE To compare the magnitude of relative oral health inequalities between Indigenous and non-Indigenous persons from Brazil, New Zealand and Australia. METHODS Data were from surveys in Brazil (2010), New Zealand (2009) and Australia (2004-06 and 2012). Participants were aged 35-44 years and 65-74 years. Indigenous and non-Indigenous inequalities were estimated by prevalence ratios (PR) and their corresponding 95% confidence intervals (CI), adjusting for sex, age and income. Outcomes included inadequate dentition, untreated dental caries, periodontal disease and the prevalence of "fair" or "poor" self-rated oral health in Australia and New Zealand, and satisfaction with mouth/teeth in Brazil (SROH). RESULTS Irrespective of country, Indigenous persons had worse oral health than their non-Indigenous counterparts in all indicators. The magnitude of these ratios was greatest among Indigenous and non-Indigenous Australians, who, after adjustments, had 2.77 times the prevalence of untreated dental caries (95% CI 1.76, 4.37), 5.14 times the prevalence of fair/poor SROH (95% CI 2.53, 10.43). CONCLUSION Indigenous people had poorer oral health than their non-Indigenous counterparts, regardless of setting. The magnitude of the relative inequalities was greatest among Indigenous Australians for untreated dental decay and poor SROH.

Abstract
Aboriginal Australians experience significant disparities in oral health with even poorer outcomes reported in rural and remote areas. The high rates of preventable dental disease in Aboriginal communities are a serious concern from a social standpoint and in terms of service provision and health care expenditure. In this review, primary research literature was comprehensively reviewed. Papers were selected if they reported designing or implementing an intervention or oral health programme specific to the needs of Aboriginal communities. Twenty-one publications fulfilled the inclusion criteria with 19 different interventions being described. Interventions were categorized using a classification adapted from the work of Whitehead (2002). The review identified interventions that aimed to reduce early childhood caries, increase services to remote communities, develop the role of Aboriginal health workers, improve oral health literacy, establish water fluoridation and provide periodontal therapy. Implementing successful oral health interventions in Aboriginal communities is a challenge that is compounded by the complex interplay between psychosocial and cultural determinants. Even interventions that follow a rigorous and consultative design have a high failure rate in Aboriginal communities if upstream determinants of health are not adequately understood and addressed.

Abstract
OBJECTIVES Diabetes mellitus and periodontal disease are highly prevalent among Indigenous Australian adults. Untreated periodontitis impacts glycaemic control in people with diabetes. The aim of this study was to report on the effect of periodontal therapy on glycaemic control among people with obesity. METHODS This subgroup analysis is limited to 62 participants with diabetes from the original 273 Aboriginal Australian adults enrolled into the PerioCardio study. Intervention participants received full-mouth non-surgical periodontal scaling during a single, untimed session while controls were untreated. Endpoints of interest included change in glycated haemoglobin (HbA1c), C-reactive protein (CRP) and periodontal status at 3 months post-intervention. RESULTS There were more females randomized to the treatment group (n = 17) than control (n = 10) while the control group had a higher overall body mass index (BMI) [mean (SD)] 33.1 (9.7 kg m-2 ) versus 29.9 (6.0 kg m-2 ). A greater proportion of males were followed up at 3 months compared to females, P = 0.05. Periodontal therapy did not significantly reduce HbA1c: ancova difference in means 0.22 mmol mol-1 (95% CI -6.25 to 6.69), CRP: ancova difference in means 0.64 (95% CI -1.08, 2.37) or periodontal status at 3 months. CONCLUSIONS Non-surgical periodontal therapy did not significantly reduce glycated haemoglobin in participants with type 2 diabetes. Reasons are likely to be multifactorial and may be influenced by persistent periodontal inflammation at the follow-up appointments. Alternatively, the BMI of study participants may impact glycaemic control via alternative mechanisms involving the interplay between inflammation and adiposity meaning HbA1c may not be amenable to periodontal therapy in these individuals.

Abstract
OBJECTIVES This study sought to: a) estimate the frequency of poor self-rated oral health as assessed by a summary measure; b) compare frequency according to sociodemographic, behavioral, and psychological distress factors; and (3) determine if psychological distress was associated with poor self-rated oral health after adjusting for confounding. METHODS Data were from a convenience sample of Indigenous Australian adults (n = 289) residing in Australia's Northern Territory. Poor self-rated oral health was defined as reported experience of toothache, poor dental appearance or food avoidance in the last 12 months. A logistic regression model was used to evaluate socio-demographic, behavioral, and psychological distress associations with poor self-rated oral health (SROH). Effects were quantified as odds ratios (OR). RESULTS The frequency of poor SROH was 73.7 percent. High psychological distress, measured by a Kessler-6 score ≥8, was experienced by 33.9 percent of participants. Poor SROH was associated with high levels of psychological distress, being older, being female, and usually visiting a dentist because of a problem. In the multivariable model, factors that were significantly associated with poor SROH after adjustment for other covariates included having a high level of psychological distress (OR 2.74, 95% CI 1.25-6.00), being female (OR 2.22, 95% CI 1.03-4.78), and usually visiting a dentist because of a problem (OR 3.57, 95% CI 1.89-6.76). CONCLUSIONS Poor self-rated oral health and high levels of psychological distress were both highly frequent among this vulnerable population. Psychological distress was significantly associated with poor self-rated oral health after adjustment for confounding.

Abstract
Observational studies and nonrandomized trials support an association between periodontal disease and atherosclerotic vascular disease. Both diseases occur frequently in Aboriginal Australians. We hypothesized that nonsurgical periodontal therapy would improve measures of arterial function and structure that are subclinical indicators of atherosclerotic vascular disease. This parallel-group, randomized, open label clinical trial enrolled 273 Aboriginal Australians aged ≥18 years with periodontitis. Intervention participants received full-mouth periodontal scaling during a single visit, whereas controls received no treatment. Prespecified primary end points measured 12-month change in carotid intima-media thickness, an indicator of arterial structure, and 3- and 12-month change in pulse wave velocity, an indicator of arterial function. ANCOVA used complete case data to evaluate treatment group differences. End points could be calculated for 169 participants with follow-up data at 3 months and 168 participants at 12 months. Intima-media thickness decreased significantly after 12 months in the intervention group (mean reduction=-0.023 [95% confidence interval {CI}, -0.038 to -0.008] mm) but not in the control group (mean increase=0.002 [95% CI, -0.017 to 0.022] mm). The difference in intima-media thickness change between treatment groups was statistically significant (-0.026 [95% CI, -0.048 to -0.003] mm; P=0.03). In contrast, there were no significant differences between treatment groups in pulse wave velocity at 3 months (mean difference, 0.06 [95% CI, -0.17 to 0.29] m/s; P=0.594) or 12 months (mean difference, 0.21 [95% CI, -0.01 to 0.43] m/s; P=0.062). Periodontal therapy reduced subclinical arterial thickness but not function in Aboriginal Australians with periodontal disease, suggesting periodontal disease and atherosclerosis are significantly associated.

Abstract
Objective: Closing the gap in life expectancy between Indigenous and other Australians within a generation is central to national Indigenous reform policy (Closing the Gap). Over time, various methods of estimating Indigenous life expectancy and with that, the life expectancy gap, have been adopted with differing, albeit non-comparable results. We present data on the extent of the gap and elucidate the pattern of use and interpretations of the different estimates of the gap, between 2007 and 2012. Methods: An extensive search was conducted for all peer-reviewed health publications citing estimates of and/or discussing the life expectancy of Indigenous Australians, for the period 2007–2012. Results: Five predominant patterns of citation of the gap estimates were identified: 20 years, 17 years, 15–20 years, 13 years, and 11.5 years for males and 9.7 years for females. Some authors misinterpret the most recent estimates as reflecting improvement from the 17-year figure, rather than the result of different methods of estimation. Support for the direct methods used to calculate Indigenous life expectancy is indicated. Conclusions and Implications: A specific estimate of the life expectancy gap has not been established among stakeholders in Indigenous health. Agreement on the magnitude of the gap is arguably needed in order to evaluate strategies aimed at improving health outcomes for Indigenous Australians. Moreover, measuring progress towards ‘closing the gap’ depends on the availability of comparable estimates, using the same techniques of measurement to assess changes over time.
