Abstract
The prevalence and severity of periodontitis are increased and advanced in diabetes. Severe periodontitis elicits adverse effects on diabetes by impairing insulin actions due to systemic microinflammation. Recent studies unveil the emerging findings and molecular basis of the bidirectional relationship between periodontitis and diabetes. In addition to conventional mechanisms such as hyperglycemia, hyperlipidemia, and chronic inflammation, deficient insulin action may play a pathogenic role in the progression of periodontitis under diabetes. Epidemiologically, from the viewpoint of the adverse effect of periodontitis on diabetes, recent studies have suggested that Asians including Japanese and Asian Americans with diabetes and mild obesity (BMI <25 kg/m2) should pay more attention to their increased risk for cardiovascular diseases. In this review, we summarize recent findings on the effect of diabetes on periodontitis from the viewpoint of abnormalities in metabolism and insulin resistance with novel mechanisms, and the influence of periodontitis on diabetes mainly focused on micro-inflammation related to mature adipose tissue and discuss future perspectives about novel approaches to interrupt the adverse interrelationship.

Abstract
Epidemiological studies suggest that the severity of periodontitis is higher in people with diabetes than in healthy individuals. Insulin resistance might play a crucial role in the pathogenesis of multiple diabetic complications and is reportedly induced in the gingiva of rodents with type 2 diabetes; however, the molecular mechanisms underlying the pathogenesis of diabetes-related periodontitis remain unclear. Therefore, we aimed to investigate whether endothelial insulin resistance in the gingiva may contribute to the pathogenesis of periodontitis as well as elucidate its underlying molecular mechanisms. We demonstrated that insulin treatment downregulated lipopolysaccharide (LPS)-induced or tumor necrosis factor α (TNFα)-induced VCAM1 expression in endothelial cells (ECs) via the PI3K/Akt activating pathway, resulting in reduced cellular adhesion between ECs and leukocytes. Hyperglycemia-induced selective insulin resistance in ECs diminished the effect of insulin on LPS- or TNFα-stimulated VCAM1 expression. Vascular endothelial cell-specific insulin receptor knockout (VEIRKO) mice exhibited selective inhibition of the PI3K/Akt pathway in the gingiva and advanced experimental periodontitis-induced alveolar bone loss via upregulation of Vcam1, Tnfα, Mcp-1, Rankl, and neutrophil migration into the gingiva compared with that in the wild-type (WT) mice despite being free from diabetes. We also observed that insulin-mediated activation of FoxO1, a downstream target of Akt, was suppressed in the gingiva of VEIRKO and high-fat diet (HFD)-fed mice, hyperglycemia-treated ECs, and primary ECs from VEIRKO. Further analysis using ECs transfected with intact and mutated FoxO1, with mutations at 3 insulin-mediated phosphorylation sites (T24A, S256D, S316A), suggested that insulin-mediated regulation of VCAM1 expression and cellular adhesion of ECs with leukocytes was attenuated by mutated FoxO1 overexpression. These results suggest that insulin resistance in ECs may contribute to the progression of periodontitis via dysregulated VCAM1 expression and cellular adhesion with leukocytes, resulting from reduced activation of the PI3K/Akt/FoxO1 axis.

Abstract
The increasing incidence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), along with global lifestyle changes, requires further in-depth research to elucidate the mechanisms and develop new treatment strategies. In addition, the number of patients with periodontal disease has increased recently, suggesting that periodontal disease is sometimes associated with systemic conditions. In this review, we summarize recent studies linking periodontal disease and NAFLD, the concept of the mouth-gut-liver axis, oral and intestinal microbiota, and liver disease. We suggest new research directions toward a detailed mechanistic understanding and novel targets for treatment and prevention. Forty years have passed since the concepts of NAFLD and NASH were first proposed. however, no effective prevention or treatment has been established. We also found that the pathogenesis of NAFLD/NASH is not limited to liver-related diseases but has been reported to be associated with various systemic diseases and an increasing number of causes of death. In addition, changes in the intestinal microbiota have been shown to be a risk factor for periodontal diseases, such as atherosclerosis, diabetes, rheumatoid arthritis, nonalcoholic fatty liver disease, and obesity.

Abstract
BACKGROUND Glycaemic control is a key component in diabetes mellitus (diabetes) management. Periodontitis is the inflammation and destruction of the underlying supporting tissues of the teeth. Some studies have suggested a bidirectional relationship between glycaemic control and periodontitis. Treatment for periodontitis involves subgingival instrumentation, which is the professional removal of plaque, calculus, and debris from below the gumline using hand or ultrasonic instruments. This is known variously as scaling and root planing, mechanical debridement, or non-surgical periodontal treatment. Subgingival instrumentation is sometimes accompanied by local or systemic antimicrobials, and occasionally by surgical intervention to cut away gum tissue when periodontitis is severe. This review is part one of an update of a review published in 2010 and first updated in 2015, and evaluates periodontal treatment versus no intervention or usual care. OBJECTIVES: To investigate the effects of periodontal treatment on glycaemic control in people with diabetes mellitus and periodontitis. SEARCH METHODS An information specialist searched six bibliographic databases up to 7 September 2021 and additional search methods were used to identify published, unpublished, and ongoing studies. SELECTION CRITERIA: We searched for randomised controlled trials (RCTs) of people with type 1 or type 2 diabetes mellitus and a diagnosis of periodontitis that compared subgingival instrumentation (sometimes with surgical treatment or adjunctive antimicrobial therapy or both) to no active intervention or 'usual care' (oral hygiene instruction, education or support interventions, and/or supragingival scaling (also known as PMPR, professional mechanical plaque removal)). To be included, the RCTs had to have lasted at least 3 months and have measured HbA1c (glycated haemoglobin). DATA COLLECTION AND ANALYSIS At least two review authors independently examined the titles and abstracts retrieved by the search, selected the included trials, extracted data from included trials, and assessed included trials for risk of bias. Where necessary and possible, we attempted to contact study authors. Our primary outcome was blood glucose levels measured as glycated (glycosylated) haemoglobin assay (HbA1c), which can be reported as a percentage of total haemoglobin or as millimoles per mole (mmol/mol). Our secondary outcomes included adverse effects, periodontal indices (bleeding on probing, clinical attachment level, gingival index, plaque index, and probing pocket depth), quality of life, cost implications, and diabetic complications. MAIN RESULTS We included 35 studies, which randomised 3249 participants to periodontal treatment or control. All studies used a parallel-RCT design and followed up participants for between 3 and 12 months. The studies focused on people with type 2 diabetes, other than one study that included participants with type 1 or type 2 diabetes. Most studies were mixed in terms of whether metabolic control of participants at baseline was good, fair, or poor. Most studies were carried out in secondary care. We assessed two studies as being at low risk of bias, 14 studies at high risk of bias, and the risk of bias in 19 studies was unclear. We undertook a sensitivity analysis for our primary outcome based on studies at low risk of bias and this supported the main findings. Moderate-certainty evidence from 30 studies (2443 analysed participants) showed an absolute reduction in HbA1c of 0.43% (4.7 mmol/mol) 3 to 4 months after treatment of periodontitis (95% confidence interval (CI) -0.59% to -0.28%; -6.4 mmol/mol to -3.0 mmol/mol). Similarly, after 6 months, we found an absolute reduction in HbA1c of 0.30% (3.3 mmol/mol) (95% CI -0.52% to -0.08%; -5.7 mmol/mol to -0.9 mmol/mol; 12 studies, 1457 participants), and after 12 months, an absolute reduction of 0.50% (5.4 mmol/mol) (95% CI -0.55% to -0.45%; -6.0 mmol/mol to -4.9 mmol/mol; 1 study, 264 participants). Studies that measured adverse effects generally reported that no or only mild harms occurred, and any serious adverse events were similar in intervention and control arms. However, adverse effects of periodontal treatments were not evaluated in most studies. AUTHORS' CONCLUSIONS Our 2022 update of this review has doubled the number of included studies and participants, which has led to a change in our conclusions about the primary outcome of glycaemic control and in our level of certainty in this conclusion. We now have moderate-certainty evidence that periodontal treatment using subgingival instrumentation improves glycaemic control in people with both periodontitis and diabetes by a clinically significant amount when compared to no treatment or usual care. Further trials evaluating periodontal treatment versus no treatment/usual care are unlikely to change the overall conclusion reached in this review.

Abstract
Periodontitis has been associated with many systemic diseases and conditions, including metabolic syndrome. Metabolic syndrome is a cluster of conditions that occur concomitantly and together they increase the risk of cardiovascular disease and double the risk of type 2 diabetes. In this review, we focus on the association between metabolic syndrome and periodontitis; however, we also include information on diabetes mellitus and cardiovascular disease, since these two conditions are significantly intertwined with metabolic syndrome. With regard to periodontitis and metabolic syndrome, to date, the vast majority of studies point to an association between these two conditions and also demonstrate that periodontitis can contribute to the development of, or can worsen, metabolic syndrome. Evaluating the effect of metabolic syndrome on the salivary microbiome, data presented herein support the hypothesis that the salivary bacterial profile is altered in metabolic syndrome patients compared with healthy patients. Considering periodontitis and these three conditions, the vast majority of human and animal studies point to an association between periodontitis and metabolic syndrome, diabetes, and cardiovascular disease. Moreover, there is evidence to suggest that metabolic syndrome and diabetes can alter the oral microbiome. However, more studies are needed to fully understand the influence these conditions have on each other.

PLoS One 2021; 16:e0249011.

Abstract
INTRODUCTION The prevalence of periodontal disease is high in diabetes patients worldwide, including Bangladesh. Although associations of periodontal disease outcomes and clinical determinants of diabetes have been investigated, few studies have reported on the relationship between periodontal diseases outcomes with modifiable factors, such as self-care and oral hygiene practices, in patients with diabetes. Moreover, in order to develop targeted strategies, it is also important to estimate their aggregated contribution separately from that of the established sociodemographic and diabetics related clinical determinates. Therefore, this study was performed to elucidate 1) the relationship of diabetes patients' self-care and oral hygiene practices to periodontal disease and 2) the relative contributions of selected factors to periodontal disease outcome in type 2 diabetes patients. METHODS The data were obtained from the baseline survey of a multicentre, prospective cohort study. A total of 379 adult patients with type 2 diabetes from three diabetic centres in Dhaka, Rajshahi and Barishal, received periodontal examinations using the community periodontal index (CPI) probe, glycated haemoglobin examination, other clinical examinations, and structured questionnaires. Multiple logistics regression analyses were performed to assess the associations between selected factors and prevalence of any periodontal disease and its severity. RESULTS More than half of the participants were female (53.8%) and 66.8% of the total participants was 21-50 years old. The prevalence of any (CPI code 2+3+4; 75.7%) and severe form (CPI code 4; 35.1%) of periodontal disease were high in type 2 diabetes patients. In multivariate analysis, the odds of periodontal disease increased with unfavourable glycaemic control indicated by HbA1c ≥ 7%, and decreased by 64%, 85% and 92% with adherence to recommended diet, physical activity, and oral hygiene practices, respectively. Diabetes self-care practice explained the highest proportion of the variance (13.9%) followed by oral hygiene practices (10.9%) by modelling any periodontal disease versus no disease. Variables of diabetes conditions and oral hygiene practices explained 10.9% and 7.3% of the variance by modelling severe (CPI code 4) or moderate (CPI code 3) forms of periodontal disease versus mild form of periodontal disease. Findings also conferred that while poor diabetes control had an individually adverse association with any form of periodontal diseases and its severity, the risk of diseases was moderated by oral hygiene practices. CONCLUSIONS This study suggested that, in addition to diabetes-related clinical determinants, self-care practices, and oral hygiene practices must be taken into consideration for prevention and control of periodontal disease in patients with diabetes.

Abstract
Aims/Introduction The association between diabetes and periodontal disease is considered to be bidirectional. However, there is still controversy surrounding the relationship between periodontal disease and type 1 diabetes. We investigated whether insulin improves periodontitis without any local treatments for periodontitis under type 1 diabetes conditions using the ligature‐induced experimental periodontitis model. Materials and Methods Type 1 diabetic rats were induced by streptozotocin injection. Experimental periodontitis was induced by ligature in normal and diabetic rats. Half of the diabetic rats were treated with insulin. Two weeks after the ligature, periodontitis was evaluated. Results Insulin treatment significantly improved inflammatory cell infiltration and inflammatory cytokine gene expression, leading to suppression of alveolar bone loss, in the periodontitis of diabetic rats. Insulin also suppressed the periodontitis‐increased nitric oxide synthase‐positive cells in periodontal tissue of the diabetic rats. Even without induction of periodontitis, diabetic rats showed decreased gingival blood flow and an increased number of nitric oxide synthase‐positive cells in the gingiva and alveolar bone loss compared with normal rats, all of which were ameliorated by insulin treatment. We further confirmed that insulin directly suppressed lipopolysaccharide‐induced inflammatory cytokine expressions in THP‐1 cells. Conclusions There were abnormalities of periodontal tissue even without the induction of periodontitis in streptozotocin‐induced diabetic rats. Insulin treatment significantly ameliorated periodontitis without local periodontitis treatment in diabetic rats. These data suggest the therapeutic impacts of insulin on periodontitis in type 1 diabetes.

Abstract
Periodontitis is a chronic inflammatory condition that may contribute to diabetogenesis. The aim was to investigate the levels of glycated proteins and their correlation with periodontal and systemic inflammation. Fifty-one patients with periodontitis and 20 healthy subjects underwent probing pocket depth (PPD) measurements. PPD total and PPD disease with and without tooth adjustment were used as continuous indices. Marginal bone loss (MBL) for mandibular premolars and molars was measured digitally. Body mass index (BMI) and waist circumference (WC) were also analyzed. Glycated hemoglobin (HbA1c) and fructosamine (FrAm) levels were measured in all subjects. A multiplex proximity extension assay (PEA) was used to analyze the serum samples for simultaneous measurement of 92 proteins. Both HbA1c and FrAm inversely correlated with IL-10, FGF-21, MCP-1, and TNF beta amongst 16 proteins. HbA1c correlated directly with OPG. Parameters of disease severity were consistently significant for HbA1c. Adjusted PPD total and number of missing teeth were increased in diabetes whereas levels of RANKL and RANKL to OPG ratio were the highest in nondiabetic periodontitis patients. Hyperglycemic conditions in periodontitis patients are associated with reduced levels of anti-inflammatory proteins as well as dysregulated bone resorption.

Abstract
It has recently become evident that the periodontium (gingiva, desmodontal ligament, cementum and alveolar bone) and the associated microbiota play a pivotal role in regulating human health and diseases. The oral cavity is the second largest microbiota in the body with around 500 different bacterial species identified today. When disruption of oral cavity and dysbiosis occur, the proportion of strict anaerobic Gram-negative bacteria is then increased. Patients with periodontitis present 27 to 53% more risk to develop diabetes than the control population suggesting that periodontitis is an aggravating factor in the incidence of diabetes. Moreover, dysbiosis of oral microbiota is involved in both periodontal and metabolic disorders (cardiovascular diseases, dyslipidaemia …). The oral diabetic dysbiosis is characterized by a specific bacteria Porphyromonas, which is highly expressed in periodontal diseases and could exacerbate insulin resistance. In this review, we will address the nature of the oral microbiota and how it affects systemic pathologies with a bidirectional interaction. We also propose that using prebiotics like Akkermansia muciniphila may influence oral microbiota as novel therapeutic strategies. The discovery of the implication of oral microbiota for the control of metabolic diseases could be a new way for personalized medicine.

Abstract
BACKGROUND Periodontitis is more common and severe in people with diabetes than the general population. We have reported in the Joslin Medalist Study that people with type 1 diabetes of ≥50 years (Medalists) may have endogenous protective factors against diabetic nephropathy and retinopathy. METHODS In this cross-sectional study, the prevalence of periodontitis according to the Centers for Disease Control/American Academy of Periodontology classification in a subset (n = 170, mean age = 64.6 ± 6.9 years) of the Medalist cohort, and its associations to various criteria of periodontitis and diabetic complications were assessed. RESULTS The prevalence of severe periodontitis in Medalists was only 13.5% which was lower than reported levels in diabetic patients of similar ages. Periodontal parameters, including bleeding on probing, plaque index, gingival index, and demographic traits, including male sex, chronological age, and age at diagnosis were significantly associated with severity of periodontitis, which did not associate with diabetes duration, hemoglobin A1c (HbA1c), body mass index, and lipid profiles. Random serum C-peptide levels inversely associated with severity of periodontitis (P = 0.03), lower probing depth (P = 0.0002), and clinical attachment loss (P = 0.03). Prevalence of cardiovascular diseases (CVD) and systemic inflammatory markers, plasma interleukin-6 (IL-6), and serum immunoglobulin G titer against Porphyromonas gingivalis positively associated with severity of periodontitis (P = 0.002 and 0.02, respectively). Antibody titer to P. gingivalis correlated positively and significantly with CVD, serum IL-6, and high-sensitivity C-reactive protein. CONCLUSIONS Some Medalists could be protected from severe periodontitis even with hyperglycemia. Endogenous protective factors for periodontitis could possibly be related to residual insulin production and lower levels of chronic inflammation.

Abstract
BACKGROUND/PURPOSE Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease affecting oral health. Evidence shows possible association between T1DM and periodontal diseases (PDs). We conducted a nationwide population-based study in Taiwan, with a 14-year follow-up to investigate the risk of PDs in T1DM patients. METHODS We used data from the National Health Insurance Research Database in Taiwan. The T1DM cohort was identified with newly diagnosed T1DM from 1998 to 2011. The non-T1DM cohort was frequency matched with the T1DM cohort. Participants comprised 4248 patients in the T1DM cohort and 16992 persons in the non-T1DM cohort. RESULTS The T1DM patients showed an increased risk of PDs compared to non-T1DM individuals [adjusted hazard ratio (aHR) = 1.45]. T1DM patients who visited the emergency room more than twice per year had a higher aHR of 13.0 for developing PDs. The aHR for PDs was 13.2 in the T1DM patients who had been hospitalized more than twice per year. CONCLUSION T1DM patients are at higher risk of developing PDs than non-T1DM individuals. Our results further showed that the number of T1DM interventions; that is, annual emergency visits and hospitalizations were associated with increased the risk of developing PDs.

Abstract
AIM Even though the association between diabetes and periodontitis is taken for granted, results on this association are conflicting within the literature. This systematic review assessed whether poorly controlled diabetes was associated with periodontitis onset or progression. METHODS Electronic searches were performed in PubMed, Scopus and Embase databases. Hand search was carried out in the reference list of all articles included. Gray literature was investigated with a Google Scholar search. Prospective longitudinal studies on the association between diabetes and periodontitis were considered for this review. Studies should have presented at least two measurements of periodontal conditions over time. Data on study design, crude and adjusted estimates were collected. We used meta-analysis to estimate the pooled effect of hyperglycemia in people with diabetes on periodontitis onset or progression. Meta-regression and subgroup analyses were employed to investigate potential sources of heterogeneity between studies. RESULTS Thirteen studies matched the inclusion criteria, comprising 49,262 individuals, including 3197 diagnosed with diabetes. Meta-analyses of adjusted estimates showed that diabetes increased the risk of incidence or progression of periodontitis by 86% (RR 1.86 [95% CI 1.3-2.8]). However, there is scarce information on the association between diabetes and periodontal destruction. CONCLUSIONS This study provides evidence that diabetes is associated with increased risk of periodontitis onset and progression in adults. Upcoming prospective longitudinal studies ought to overcome methodological caveats identified in this review.

Abstract
BACKGROUND The aim of this study was to compare the oral health status of children with type 1 diabetes and healthy controls. METHODS This comparative study involved 64 children, 32 children with type 1 diabetes and 32 age- and gender-matched controls. Oral health examination was conducted using WHO criteria. Dental caries experience was recorded using DMFT/dmft index and periodontal parameters were assessed using plaque, gingivitis, gingival bleeding and calculus indexes. Dental caries and periodontal parameters between the two groups were compared using the Mann-Whitney U-test. RESULTS Children with diabetes exhibited significantly greater plaque deposits (p=0.01) and a higher mean plaque index (p<0.01), when compared to healthy subjects. No significant difference in DMFT and dmft scores, mean bleeding index, calculus index and gingival index was found between the two groups. CONCLUSIONS Children with type 1 diabetes had a poor oral health status with greater plaque accumulation than children without diabetes.

Abstract
BACKGROUND AND OBJECTIVE Periodontal disease is a chronic infectious disease that results in bone loss. Many epidemiological studies have reported the progression of periodontal tissue destruction in patients with diabetes; however, the associated mechanism remains unclear. In this study, we comprehensively investigated how diabetes affects the periodontal tissue and alveolar bone loss using a ligature-induced periodontitis model in streptozotocin-induced diabetic (STZ) mice. MATERIAL AND METHODS Diabetes was induced by intraperitoneal injection with streptozotocin in 6-wk-old C57/BL6J male mice. A silk ligature was tied around the maxillary left second molar in 9-wk-old wild-type (WT) and STZ mice. Bone loss was evaluated at 3 and 7 d after ligation. mRNA expression levels in the gingiva between the two groups were examined by DNA microarray and quantitative polymerase chain reaction at 1, 3 and 7 d post-ligation. Tartrate-resistant acid phosphatase and alkaline phosphatase staining of the periodontal tissue was performed for evaluation of osteoclasts and osteoblasts in histological analysis. RESULTS In the gingiva, hyperglycemia upregulated the osteoprotegerin (Opg) mRNA expression and downregulated Osteocalcin mRNA expression. In the ligated gingiva, tumor necrosis factor-α (Tnf-α) mRNA expression was upregulated at 1 d post-ligation in STZ mice but not in WT mice. At 3 d post-ligation, alveolar bone loss was observed in STZ mice, but not in WT mice. Significantly severe alveolar bone loss was observed in STZ mice compared to WT mice at 7 d post-ligation. Bone metabolic analysis using DNA microarray showed significant downregulation in the mRNA expression of glioma-associated oncogene homologue 1 (Gli1) and collagen type VI alpha 1 (Col6a1) at the gingiva of the ligated site in STZ mice compared to that in WT mice. Quantitative polymerase chain reaction showed that Gli1 and Col6a1 mRNA expression levels were significantly downregulated in the gingiva of the ligated site in STZ mice compared to WT mice. Histological analysis showed lower alkaline phosphatase activity in STZ mice. In addition, an increased number of tartrate-resistant acid phosphatase-positive multinucleated cells were observed at the ligated sites in STZ mice. CONCLUSIONS These results suggest that an imbalance of bone metabolism causes osteoclastosis in insulin-deficient diabetes, and that alveolar bone loss could occur at an early phase under this condition.

Abstract
BACKGROUND Glycaemic control is a key issue in the care of people with diabetes mellitus (DM). Periodontal disease is the inflammation and destruction of the underlying supporting tissues of the teeth. Some studies have suggested a bidirectional relationship between glycaemic control and periodontal disease. This review updates the previous version published in 2010. OBJECTIVES The objective is to investigate the effect of periodontal therapy on glycaemic control in people with diabetes mellitus. SEARCH METHODS We searched the following electronic databases: the Cochrane Oral Health Group Trials Register (to 31 December 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2014, Issue 11), MEDLINE via OVID (1946 to 31 December 2014), EMBASE via OVID (1980 to 31 December 2014), LILACS via BIREME (1982 to 31 December 2014), and CINAHL via EBSCO (1937 to 31 December 2014). ZETOC (1993 to 31 December 2014) and Web of Knowledge (1990 to 31 December 2014) were searched for conference proceedings. Additionally, two periodontology journals were handsearched for completeness, Annals of Periodontology (1996 to 2003) and Periodontology 2000 (1993 to 2003). We searched the US National Institutes of Health Trials Registry (http://clinicaltrials.gov) and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We searched for randomised controlled trials (RCTs) of people with type 1 or type 2 DM (T1DM/T2DM) with a diagnosis of periodontitis. Interventions included periodontal treatments such as mechanical debridement, surgical treatment and antimicrobial therapy. Two broad comparisons were proposed:1. periodontal therapy versus no active intervention/usual care;2. periodontal therapy versus alternative periodontal therapy. DATA COLLECTION AND ANALYSIS For this review update, at least two review authors independently examined the titles and abstracts retrieved by the search, selected the included trials, extracted data from included trials and assessed included trials for risk of bias.Our primary outcome was blood glucose levels measured as glycated (glycosylated) haemoglobin assay (HbA1c).Our secondary outcomes included adverse effects, periodontal indices (bleeding on probing (BOP), clinical attachment level (CAL), gingival index (GI), plaque index (PI) and probing pocket depth (PPD)), cost implications and diabetic complications. MAIN RESULTS We included 35 studies (including seven from the previous version of the review), which included 2565 participants in total. All studies used a parallel RCT design, and 33 studies (94%) only targeted T2DM patients. There was variation between studies with regards to included age groups (ages 18 to 80), duration of follow-up (3 to 12 months), use of antidiabetic therapy, and included participants' baseline HbA1c levels (from 5.5% to 13.1%).We assessed 29 studies (83%) as being at high risk of bias, two studies (6%) as being at low risk of bias, and four studies (11%) as unclear. Thirty-four of the studies provided data suitable for analysis under one or both of the two comparisons.Comparison 1: low quality evidence from 14 studies (1499 participants) comparing periodontal therapy with no active intervention/usual care demonstrated that mean HbA1c was 0.29% lower (95% confidence interval (CI) 0.48% to 0.10% lower) 3 to 4 months post-treatment, and 0.02% lower after 6 months (five studies, 826 participants; 95% CI 0.20% lower to 0.16% higher).Comparison 2: 21 studies (920 participants) compared different periodontal therapies with each other. There was only very low quality evidence for the multiple head-to-head comparisons, the majority of which were unsuitable to be pooled, and provided no clear evidence of a benefit for one periodontal intervention over another. We were able to pool the specific comparison between scaling and root planing (SRP) plus antimicrobial versus SRP and there was no consistent evidence that the addition of antimicrobials to SRP was of any benefit to delivering SRP alone (mean HbA1c 0.00% lower: 12 studies, 450 participants; 95% CI 0.22% lower to 0.22% higher) at 3-4 months post-treatment, or after 6 months (mean HbA1c 0.04% lower: five studies, 206 patients; 95% CI 0.41% lower to 0.32% higher).Less than half of the studies measured adverse effects. The evidence was insufficient to conclude whether any of the treatments were associated with harm. No other patient-reported outcomes (e.g. quality of life) were measured by the included studies, and neither were cost implications or diabetic complications.Studies showed varying degrees of success with regards to achieving periodontal health, with some showing high levels of residual inflammation following treatment. Statistically significant improvements were shown for all periodontal indices (BOP, CAL, GI, PI and PPD) at 3-4 and 6 months in comparison 1; however, this was less clear for individual comparisons within the broad category of comparison 2. AUTHORS' CONCLUSIONS There is low quality evidence that the treatment of periodontal disease by SRP does improve glycaemic control in people with diabetes, with a mean percentage reduction in HbA1c of 0.29% at 3-4 months; however, there is insufficient evidence to demonstrate that this is maintained after 4 months.There was no evidence to support that one periodontal therapy was more effective than another in improving glycaemic control in people with diabetes mellitus.In clinical practice, ongoing professional periodontal treatment will be required to maintain clinical improvements beyond 6 months. Further research is required to determine whether adjunctive drug therapies should be used with periodontal treatment. Future RCTs should evaluate this, provide longer follow-up periods, and consider the inclusion of a third 'no treatment' control arm.Larger, well conducted and clearly reported studies are needed in order to understand the potential of periodontal treatment to improve glycaemic control among people with diabetes mellitus. In addition, it will be important in future studies that the intervention is effective in reducing periodontal inflammation and maintaining it at lowered levels throughout the period of observation.

The search included all studies published from inception of database to January 2014. A total of 1179 abstracts were analyzed for selection in 2 phases. The first phase selection was based on the title and abstracts alone. The selected abstracts were then included for second phase, where full articles were obtained. The selection was carried out by 2 independent reviewers (Kappa value=0.809). Only 37 articles were included for final analysis in this review. RESULTS There is conflicting evidence in the caries experience between children with type 1 diabetes and healthy children. For periodontal health, most studies reported significantly greater plaque accumulation and higher gingival index in children with type 1 diabetes. Cohort studies reported no significant differences in perioodontal parameters over time. CONCLUSIONS There is conflicting evidence regarding the caries experience of children with type 1 diabetes, but they exhibit poorer periodontal health status with greater plaque accumulation compared to healthy children. Further studies are warranted to assess the oral health status of children with type 1 diabetes.

Abstract
Background: Patients with type 2 diabetes have an increased prevalence of periodontitis and, in turn, periodontitis adversely affects the diabetic status. Oxidative stress plays a key role in affecting the pathophysiology of both the diseases and adjunctive systemic antioxidant therapy may have beneficial effect on the treatment outcome. This study was planned to compare the efficacy of systemic antioxidant therapy with lycopene as an adjunct to scaling and root planing versus scaling and root planing alone in chronic periodontitis patients with type 2 diabetes mellitus. Materials and Methods: 40 diabetic subjects with periodontitis, attending the OP wing of the Department of Periodontics of a tertiary referral care hospital were randomized and equally divided into group A and group B. Diabetes status was recorded as per ADA guidelines and the periodontitis status as per American Academy of Periodontology (AAP) guidelines. Group A patients underwent scaling and root planing with administration of lycopene 8 mg and group B patients were treated with scaling and root planing alone. Clinical parameters like gingival index (GI), probing depth (PD), and clinical attachment level (CAL) were recorded. Serum markers, i.e. malondialdehyde (MDA) (TBARS assay) and C reactive protein (CRP) (ELISA), and glycated hemoglobin (HbA1c) levels were assessed at baseline and at 2 months and 6 months post-therapy. Results: Inter-group comparison showed group A giving statistically significant results in reducing mean serum MDA levels at 2 months and 6 months, and in reducing mean PD (mm) and mean HbA1c (%) levels at 2 months (P < 0.005). Conclusion: Lycopene as an adjunctive treatment was effective in reducing oxidative stress and restoring altered glycemic levels. Further longitudinal studies with a larger sample size are required to establish the role of lycopene in the management of chronic periodontitis.

Abstract
The association between diabetes mellitus and chronic periodontal disease has long been established. Most of the researches linking these two very common chronic diseases were based on type 2 diabetes mellitus and chronic periodontal disease. However, this study was conducted to investigate the association between type 1 diabetes and chronic periodontal disease in Malaysian subjects. Forty-one Malaysian subjects, of which 20 subjects were type 1 diabetics and with chronic periodontal disease (test group) and 21 subjects with only chronic periodontal disease (control group), were included in the study. Periodontal parameters and plaque samples for microbiological evaluation were done at baseline, 2 and 3 months after nonsurgical periodontal therapy. Blood samples were taken from only the test group and evaluated for HbA1c at baseline and 3 months after periodontal therapy. There were no statistically significant difference in periodontal parameters between groups (P>0.05) and no significant improvement in the level of HbA1c in the test group. Microbiological studies indicated that there were significant reductions in the levels of the tested pathogens in both groups. The results of our study were similar to the findings of several other studies that had been done previously.

Abstract
This study was aimed at the histological investigation of the impact of experimental diabetes on the healthy gingiva of rats. Thirty male Wistar rats were used in this study. The animals were randomly divided into two groups (n = 15) prior to the experiment. Group 1 experimental diabetes was created by streptozotocin injection in 15 rats. Group 2 comprised the control group (15 rats). On the 7th, 14th and 21st days after the induction of diabetes by streptozotocin, five animals from each group were euthanized by cardiac puncture. The gingiva of the maxillary left first molar tooth of the sacrificed animals was extracted for histological examination. Histological examination demonstrated that, when compared to the control group, the diabetes group displayed marked hyperkeratosis and parakeratosis of the gingival epithelium on day 21 post-induction. Furthermore, the diabetes group presented with an increased number of inflammatory cells and vasodilatation of the capillaries, in comparison to the controls. The overall evaluation of the findings obtained in this study suggested that diabetes alone could cause changes in the periodontium and affect periodontal health.

Abstract
A bidirectional relationship between diabetes mellitus (DM) and periodontal diseases (PDs) has been established. It is estimated that patients with poorly controlled DM are 3 times more likely to develop chronic PD compared with normoglycemic individuals despite similar composition in subgingival biofilms. Furthermore, these patients present with increased severity and rapid progression of attachment loss around teeth resulting in edentulism. Treatment of PD results in a modest but significant improvement in glycemic control in patients with DM reflected by a 0.4 % reduction in HbA1c-glycated hemoglobin levels. Compelling evidence from in vitro and animal studies supports a plausible biological explanation for the relationship between the 2 conditions centered on systemic low-grade inflammation. However, the limited number of comparable large randomized clinical trials is reflected in the limited specific guidelines offered by the international organizations for DM and PD regarding the management of the 2 diseases in an individual.

Abstract
BACKGROUND AND OBJECTIVE Human β-defensins (hBDs) have a strong antibacterial action against various microorganisms, especially periodontal pathogens. The aim of this study was to compare the total levels of hBD-1 and hBD-3 in the gingival crevicular fluid of healthy patients with gingivitis (HG), healthy patients with chronic periodontitis (HP), patients with type 2 diabetes mellitus (DM) and gingivitis (DM2G) and patients with type 2 DM and chronic periodontitis (DM2P). MATERIAL AND METHODS A total of 80 patients were included: 20 HG, 20 HP, 20 DM2G and 20 DM2P. The levels of hBD-1 and hBD-3 in gingival crevicular fluid were measured using ELISA. RESULTS The DM2P group had significantly higher periodontal clinical parameters at sites from which gingival crevicular fluid was collected compared with the other groups. The HG group had significantly lower periodontal clinical parameters within the gingival crevicular fluid-collected sites than did the HP, DM2G and DM2P groups. The gingival crevicular fluid of the DM2P group had significantly higher levels of total hBD-1 and hBD-3 than did that of the other groups; the hBD-1 and hBD-3 levels were significantly higher in the gingival crevicular fluid of the DM2G group than in that of the the non-DM type 2 groups (HG and HP). The gingival crevicular fluid of the HP group had significantly higher levels of total hBD-1 and hBD-3 in comparison with that of the HG group. CONCLUSION As a result of the observed vascular and cell activity changes that occur within patients diagnosed with DM, periodontal diseases become more severe. These changes hinder the migration and the ability of chemotactic factors and leukocytes to protect periodontal tissues from the effects of microorganisms. In order to eliminate microorganisms, the epithelial cells in patients with DM may release more hBD-1 and hBD-3 into the gingival crevicular fluid. Determining the amount of hBD-1 and hBD-3 in the gingival crevicular fluid of patients with and without DM will help to elucidate the relationship among hBD-1, hBD-3, DM and periodontal disease.

Abstract
OBJECTIVE To explore associations between diabetes etiology (type 1 diabetes mellitus [T1DM] vs. T2DM) and glycemic control in the prediction of 5-year periodontal status change. RESEARCH DESIGN AND METHODS The Study of Health in Pomerania (SHIP) is a population-based stratified sample of German men and women. Healthy participants and those determined to have T2DM arose from the SHIP cohort, and T1DM participants were recruited from diabetes clinics in the catchment area that gave rise to SHIP. Dentate participants (n = 2,626; 53% women; 20-81 years of age) were included. Diabetes was determined via physician diagnosis and/or HbA(1c) ≥6.5% (uncontrolled diabetes >7.0%). Examiners blinded to diabetes status performed random half-mouth periodontal examinations, assessing probing depth (PD) and attachment loss (AL) (four sites/tooth) at baseline and follow-up. Participants were categorized into six groups as follows: 1) diabetes free (n = 2,280), 2) incident T2DM (n = 79), 3) controlled T2DM (n = 80), 4) uncontrolled T2DM (n = 72), 5) controlled T1DM (n = 43), and 6) uncontrolled T1DM (n = 72). In multivariable regressions, mean PD change (ΔMPD), mean AL change (ΔMAL), or incident tooth-loss values were regressed across the aforementioned diabetes categories. RESULTS Mean (SD) ΔMPD and ΔMAL values among all participants were -0.08 ± 0.5 mm and 0.08 ± 1.03 mm, respectively, and 34% lost one or more teeth. Relative to diabetes-free participants, those with uncontrolled T2DM experienced greater ΔMPD ± SE (P < 0.05), whereas participants with either uncontrolled T1DM or uncontrolled T2DM realized greater ΔMAL (P < 0.05). Uncontrolled T1DM and T2DM were both associated with an increased risk of future tooth loss (P < 0.05). CONCLUSIONS Diabetes control, but not etiology, was associated with future tooth loss and accelerated AL progression.

Abstract
Periodontal diseases comprise a large group of predominantly infectious and/or inflammatory disorders affecting periodontal tissues. They are diagnosed by assessment of the dento-gingival area, including the the gingival sulcus depth, and the presence of bleeding with radiographic assessment of the alveolar bone. The prevalence of periodontitis (PD) is reported to be 20-50% worldwide;(1) while the aggressive form of PD is found in less than 10% of the population/2,3). Periodontitis is a chronic infectious/inflammatory disease of multi-factorial etiology(4) with a number of risk factors that are shared with other chronic inflammatory conditions; increasing age, low socio-economic conditions, stress, increased body weight, dyslipidemia, hypertension, metabolic syndrome, cigarette smoking and Diabetes mellitus.(5-6) Systemic reviews have shown a clear association between PD and coronary heart diseases (CHD) emphasizing the need to consider PD as a risk factor for CHD.

Abstract
Abstract Periodontitis is a common complication in patients with diabetes. Their classificationis complex and it is based on the clinical presentation, rate of disease progression,age at diagnosis and local and systemic factors that may multiply the risk. The twomajor stages of periodontal diseases are gingivitis and periodontitis. Therelationship between these two diseases appears bidirectional insofar that theexistence of one disease tends to promote the other and that the meticulousmanagement of either may help the treatment of the other. Treatment of periodontitisusing a association of mechanical therapy, scaling and root planning, plus systemictetracycline antibiotics has been demonstrated to have important reductions inHbA1c values. Therefore, for a better control of diabetes we suggest that periodontalpatients with diabetes should be consulted and treated by a periodontist.

Abstract
More than several hundreds of millions of people will be diabetic and obese over the next decades in front of which the actual therapeutic approaches aim at treating the consequences rather than causes of the impaired metabolism. This strategy is not efficient and new paradigms should be found. The wide analysis of the genome cannot predict or explain more than 10-20% of the disease, whereas changes in feeding and social behavior have certainly a major impact. However, the molecular mechanisms linking environmental factors and genetic susceptibility were so far not envisioned until the recent discovery of a hidden source of genomic diversity, i.e., the metagenome. More than 3 million genes from several hundreds of species constitute our intestinal microbiome. First key experiments have demonstrated that this biome can by itself transfer metabolic disease. The mechanisms are unknown but could be involved in the modulation of energy harvesting capacity by the host as well as the low-grade inflammation and the corresponding immune response on adipose tissue plasticity, hepatic steatosis, insulin resistance and even the secondary cardiovascular events. Secreted bacterial factors reach the circulating blood, and even full bacteria from intestinal microbiota can reach tissues where inflammation is triggered. The last 5 years have demonstrated that intestinal microbiota, at its molecular level, is a causal factor early in the development of the diseases. Nonetheless, much more need to be uncovered in order to identify first, new predictive biomarkers so that preventive strategies based on pre- and probiotics, and second, new therapeutic strategies against the cause rather than the consequence of hyperglycemia and body weight gain.

Abstract
AIM To compare levels of periodontitis in non-smoking type 1 diabetic patients and controls. MATERIAL AND METHODS Type 1 diabetic patients, aged 20-55 years, were recruited from outpatient clinics at five hospitals in Glasgow, UK. Control subjects were recruited from physiotherapy clinics, using the buddy system and through an advertisement in a free newspaper. The primary outcome was severe periodontitis defined by clinical attachment level ≥6 mm on ≥1 tooth. RESULTS There were 34 well controlled patients (HbA1c ≤ 7.5%), 169 poorly controlled patients and 112 non-diabetic subjects. Prevalence of severe periodontitis was higher in all type 1 diabetic patients [24.1% (95% CI: 18.4-30.6%)] and poorly controlled patients [27.2% (20.7-34.6%)] than in controls [20.5% (13.5-29.2%)]. The fully adjusted odds ratios (ORs) in never smokers comparing the whole diabetic group, and the poorly controlled group, with the control group were 1.35 [0.66-2.8] (p = 0.41) and 1.58 [0.75-3.33] (p = 0.23), respectively. Mean clinical attachment level was higher in all type 1 diabetic and poorly controlled patients than in controls (both p < 0.001). CONCLUSIONS These results indicate worse periodontal health in type 1 diabetic patients than in control subjects. TRIAL REGISTRATION This study was registered with the UKCRN, ID: 9314 and Scottish Diabetes Research Network registration number: 128.

Abstract
This paper has been written to both refresh and update clinicians' knowledge of diabetes. Treatment for patients with diabetes continues to develop with the majority of Type 1 diabetics now using multiple daily injections and an increasing minority using insulin pumps. Blood glucose monitoring and patient education programmes have resulted in more patient involvement in controlling this condition. Type 2 diabetics have had improvement in care provision through the development of shorter acting sulphonylureas and the potential for GLP1 injections. The impact of diabetes on both oral health and quality of life is discussed. Practical suggestions are made regarding the dental treatment of diabetic patients using both local anaesthetic and under sedation. Diabetes continues to be a fickle master for those affected by this condition. The paper is written from the perspective of the 'expert patient'. It is hoped that a greater understanding of this chronic condition will improve both access to, and safety of, dental care for those patients with diabetes.

Abstract
The main aim of this review is to update the reader with practical knowledge concerning the relationship between diabetes mellitus and periodontal diseases. Exclusive data is available on the association between these two chronic diseases till date. Articles published on this relationship often provide the knowledge of definitions of diabetes mellitus and periodontal diseases, prevalence, extent, severity of periodontal disease, complications of diabetes along with the possible underlying mechanisms. The authors reviewed human epidemiological studies, cross-sectional observations and longitudinal cohort, case control that evaluated variables exclusively over the past 30 years and the predominant findings from the “certain” articles are summarized in this review. This review clarifies certain queries such as 1) Do periodontal diseases have an effect on the metabolic control of diabetes? 2) Does diabetes act as a risk factor of periodontitis? 3) What are the possible underlying mechanisms relating the connection between these two chronic diseases? 4) What is the effect of periodontal intervention on metabolic control of diabetes? After a thorough survey of literature, it was observed that diabetes acts as a risk factor in development of periodontitis as periodontitis is significantly aggravated in patients suffering from diabetes having long term hyperglycemia. Different mechanisms underlying the association between the accelerated periodontal disease and diabetes are emerging but still more work is required. Major efforts are required to elucidate the impact of periodontal diseases on diabetes. At the same time, patients are needed to be made aware of regular periodontal maintenance schedule and oral hygiene.

Abstract
Diabetes mellitus (a group of metabolic disorders characterized by hyperglycemia) and periodontitis (a microbially induced inflammatory disorder that affects the supporting structures of teeth) are both common, chronic conditions. Multiple studies have demonstrated that diabetes mellitus (type 1 and type 2) is an established risk factor for periodontitis. Findings from mechanistic studies indicate that diabetes mellitus leads to a hyperinflammatory response to the periodontal microbiota and also impairs resolution of inflammation and repair, which leads to accelerated periodontal destruction. The cell surface receptor for advanced glycation end products and its ligands are expressed in the periodontium of individuals with diabetes mellitus and seem to mediate these processes. The association between the two diseases is bidirectional, as periodontitis has been reported to adversely affect glycemic control in patients with diabetes mellitus and to contribute to the development of diabetic complications. In addition, meta-analyses conclude that periodontal therapy in individuals with diabetes mellitus can result in a modest improvement of glycemic control. The effect of periodontal infections on diabetes mellitus is potentially explained by the resulting increase in levels of systemic proinflammatory mediators, which exacerbates insulin resistance. As our understanding of the relationship between diabetes mellitus and periodontitis deepens, increased patient awareness of the link between diabetes mellitus and oral health and collaboration among medical and dental professionals for the management of affected individuals become increasingly important.

Abstract
DATA SOURCES The Cochrane Oral Health Group's Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL), Medline, EMBASE, CINAHL, ZETOC, ISIWeb of Knowledge and LILACS databases were searched together with hand searches of the journals Annals of Periodontology (1996 to 2003) and Periodontology 2000 (1993 to 2003).There were no language restrictions. STUDY SELECTION This review included randomised controlled trials of people with type 1 or 2 diabetes mellitus (DM) with a diagnosis of periodontitis. Suitable interventions included mechanical periodontal therapy with or without adjunctives and oral hygiene education. DATA EXTRACTION AND SYNTHESIS The titles and abstracts of all identified papers were examined by two review authors' independently. All included trials were assessed for risk of bias. Data were collated in evidence tables, grouped according to research design and assessed for possible meta-analysis on the basis of homogeneity of main characteristics. RESULTS Seven studies were included and three studies had results pooled into a meta-analysis. The effect for the mean percentage difference in HbA1c for scaling/root planing and oral hygiene (+/- antibiotic therapy) versus no treatment/usual treatment after 3/4 months was -0.40% (95% confidence interval (CI) fixed effect -0.78% to -0.01%), representing a statistically significant reduction in HbA1c (P = 0.04) for scaling/root planing. One study was assessed as being at low risk of bias with the other two at moderate to high risk of bias. A subgroup analysis examined studies without adjunctive antibiotics -0.80% (one study: 95% CI -1.73% to 0.13%; P = 0.09), with adjunctive antibiotics in the test group -0.36% (one study: 95% CI -0.83% to 0.11%; P = 0.14), and with antibiotics in both test and control groups after 3/4 months -0.15% (one study: 95% CI -1.04% to 0.74%; P = 0.74). CONCLUSIONS There is some evidence of improvement in metabolic control in people with diabetes, after treating periodontal disease. There are few studies available and individually these lacked the power to detect a significant effect. Most of the participants in the study had poorly controlled type 2 DM and there was little data from randomised trials on the effects on people with type 1 DM. Improving periodontal health is an important objective in itself. However, in order to understand the potential of this treatment to improve glycaemic control among people with diabetes, larger, carefully conducted and reported studies are needed.

Abstract
BACKGROUND Glycaemic control is a key issue in the care of people with diabetes mellitus (DM). Some studies have suggested a bidirectional relationship between glycaemic control and periodontal disease. OBJECTIVES To investigate the relationship between periodontal therapy and glycaemic control in people with diabetes and to identify the appropriate future strategy for this question. SEARCH STRATEGY A comprehensive approach was adopted employing handsearching; searching of electronic databases including the Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE, EMBASE, CINAHL, ZETOC, ISI Web of Knowledge and LILACS; contact with appropriate non-English language healthcare professionals; authors and organisations. The final date for searching for studies was 24th March 2010. SELECTION CRITERIA This review studied randomised controlled trials of people with Type 1 or 2 diabetes mellitus (DM) with a diagnosis of periodontitis. Suitable interventions included mechanical periodontal therapy with or without adjunctives and oral hygiene education. DATA COLLECTION AND ANALYSIS The titles and abstracts of 690 papers were examined by two review authors independently. Ultimately, seven studies were included and 19 excluded after full text scrutiny. All trials were assessed for risk of bias. MAIN RESULTS Three studies had results pooled into a meta-analysis. The effect for the mean percentage difference in HbA1c for scaling/root planing and oral hygiene (+/- antibiotic therapy) versus no treatment/usual treatment after 3/4 months was -0.40% (95% confidence interval (CI) fixed effect -0.78% to -0.01%), representing a statistically significant reduction in HbA1c (P = 0.04) for scaling/root planing.

Abstract
OBJECTIVE To evaluate periodontal condition of diabetic children and its related factors. METHODS The plaque index (PI), sites with bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) were evaluated in all occlusion permanent teeth of 168 non smoking type 1 diabetic children, 13 +/- 3.5 years old. The PI and BOP evaluations were also performed in deciduous teeth. RESULTS It was observed a prevalence of 20.8% of gingivitis and 5.9% of periodontitis. Those individuals with poor metabolic control had higher percentage of affected sites on PD (p = 0.004) and on CAL (p = 0.014). Patients having more than five years with diabetes mellitus type 1 showed higher percentual of affected sites on PD (p = 0.002), on BOP (p < 0.001) and on CAL (p = 0.007). CONCLUSIONS DM1 duration and poor glycemic control were significantly associated with periodontal disturbances suggesting higher susceptibility of this population in developing DP.

Abstract
OBJECTIVE The objective of this study consisted in determining the variability of the ANB angle in relation to the position of the A- and B-points in the sagittal vertical plane. MATERIALS AND METHODS Using a theoretical model, we varied the position of the cephalometric points A and B in the sagittal vertical plane while its sagittal relationship was kept constant (Wits value = 0 mm). For this purpose, seven lines were erected perpendicular to the occlusal plane on a lateral cephalogram. The position of points A and B were determined on each of the vertical lines by calculating one anterior and one posterior angle in each case. In this way, the positions of all A- and B-points were clearly defined in the sagittal vertical plane. RESULTS The characteristic of the ANB angle in the sagittal vertical plane was graphically represented by determining both points A and B using two angles instead of one. This revealed that the ANB angle for the same sagittal base relationship was characterized by major variations depending on the position of the A- and B-points in relation to the anterior cranial base. The larger the SNA and SNB angles were, the larger the corresponding ANB angle. At the same time, the absolute value of ANB increased with the length of the vertical distance between the points A and B. CONCLUSION The ANB angle is strongly influenced by geometric factors. Accurate diagnosis of the sagittal base relationship should thus take the individual character of the ANB angle into account.

Abstract
AIM In a general adult population, we have demonstrated an inverse association between periodontitis and respiratory allergies that is in line with the hygiene hypothesis suggesting a protective effect of infections against the development of allergies. The objective of the present study was to investigate the association between periodontitis and respiratory allergies in a type 1 diabetes mellitus population. MATERIAL AND METHODS The study population comprised 170 patients with type 1 diabetes mellitus aged 17-80 years. Respiratory allergies were present in 22 subjects. The attachment loss (AL) was measured. Periodontitis was defined according to the percentage of surfaces that exceeded 3 mm AL (healthy, mild, moderate, severe periodontal conditions). RESULTS Our adjusted analyses revealed an inverse association between periodontitis and respiratory allergies. For increasing AL, a trend towards a decreasing risk was present for respiratory allergies (p(trend)<0.05). Compared with subjects with healthy periodontal conditions, individuals with severe periodontal conditions had the lowest risk of respiratory allergies [odds ratios (OR) 0.06 (95% confidence interval (CI) 0.01-0.39)], followed by subjects with moderate AL [OR 0.14 (95% CI 0.03-0.63)] and mild AL [OR 0.32 (95% CI 0.09-1.08)]. CONCLUSION There is a strong inverse association between periodontitis and respiratory allergies in patients with type 1 diabetes mellitus. These findings further support the hygiene hypothesis.

Abstract
Diabetes mellitus is a common and growing global health problem leading to several complications. Among these periodontal diseases are considered as the sixth complication of diabetes mellitus. This article reviews the relationship between diabetes and oral health, particularly focusing on periodontal diseases, dental caries and xerostomia. There is a bidirectional interrelationship between diabetes and periodontal diseases. Periodontitis is more prevalent and severe in patients with diabetes than in normal population. Therapy of periodontal infection contributes to a positive glycaemic control management and enables reduction of the burden of complications of diabetes mellitus. Diabetics have an increased predisposition to the manifestation of oral diseases like candidiasis which is associated with poor glycaemic control and therapeutic dentures. This predisposition also contributes to xerostomia, which may be due to increased glucose levels in oral fluids or immune dysregulation.

Abstract
BACKGROUND Alterations in tissue osmotic pressure (OP) and vasculature are considered to be the inevitable aspects of an inflammatory process that subsequently alter the fluid dynamics of the tissues involved. The aim of this study was to reveal a profile of OP and vascular changes in periodontally healthy gingival tissues and analyze the relationship between them in diabetes mellitus (DM) to evaluate the possible effects of DM on the fluid dynamics of the periodontium. METHODS Experimental DM was created by intraperitoneal streptozotocin injection in 10 periodontally healthy rats. These rats were used as the test group, and 10 systemically and periodontally healthy rats served as the control group. Gingival tissue samples obtained from the groups were used for the test procedures. OP was measured in the supernatants of these samples by a semimicrodigital osmometer. Vasculature was assessed as the alterations in vascularization (vessel number [VN]) and vasodilatation (vessel diameter [VD]) by histomorphometric means. RESULTS There was a gross increase in the OP level of the test group (172.7 +/- 59.7 mOsm/kg) compared to the control group (11.4 +/- 4.2 mOsm/kg; P <0.001). VN was found to be significantly larger in the test group (12.7 +/- 2.8) than in the control group (6.8 +/- 1.1; P <0.001). VD was found to be smaller in the test group (10.1 +/- 2.8 microm) than in the control group (15.5 +/- 2.4 microm), and this difference was statistically significant (P <0.001). A positive correlation between OP and VN (r = 0.77; P <0.001) and a negative correlation between OP and VD (r = 0.1; P >0.05) were observed in the test group. CONCLUSION Our results reveal that the fluid dynamics of periodontal soft tissues may be affected by the diabetic conditions in this diabetic model because of the increased OP and VN during the pathogenesis of the disease.

Abstract
OBJECTIVES We are conducting a clinical trial of the efficacy of periodontal therapy in the improvement of glycaemic control in veterans with poorly controlled diabetes. This report describes study design, recruitment and randomization and compares baseline characteristics of the sample frame with those randomized into study groups. METHODS Veterans with poorly controlled diabetes were randomized in two groups: immediate periodontal therapy ("early treatment") or usual care followed by periodontal therapy ("deferred treatment"). Half of each group continued care for 12 months; the other half returned to their usual care. We studied baseline patient characteristics, self-reported health measures, and clinical examination data. We examined means for continuous variables, frequencies for categorical variables and compared groups using t-tests and chi(2) tests (alpha=0.05 for both). RESULTS The 193 randomized participants were younger (58 years) and had slightly higher HbA1c (10.2%) than the 2534 non-randomized participants (64 years, HbA1c =9.8%). The deferred treatment group was more likely than the early treatment group to have a history of stroke, transient ischaemic attacks, and less likely to be current or former smokers. CONCLUSIONS The mechanism for randomization was largely successful in this study.

Abstract
OBJECTIVES Report results of a randomized-clinical trial of the efficacy of periodontal care in the improvement of glycemic control in 165 veterans with poorly controlled diabetes over 4 months. METHODS Outcomes were change in Haemoglobin A1c (HbA1c) in the Early Treatment versus untreated (Usual Care) groups and percent of participants with decreases in HbA1c. Analyses included simple/multiple variable linear/logistic regressions, adjusted for baseline HbA1c, age, and duration of diabetes. RESULTS Unadjusted analyses showed no differences between groups. After adjustment for baseline HbA1c, age, and diabetes duration, the mean absolute HbA1c change in the Early Treatment group was -0.65% versus -0.51% in the Usual Care group (p=0.47). Adjusted odds for improvement by 0.5% in the Early Treatment group was 1.67 (95% confidence interval: 0.84, 3.34, p=0.14). Usual Care subjects were twice as likely to increase insulin from baseline to 4 months (20% versus 11%, p=0.12) and less likely to decrease insulin (1% versus 6%, p=0.21) than Early Treatment subjects. Among insulin users at baseline, more increased insulin in the Usual Care group (40% versus 21%, p=0.06). CONCLUSIONS No significant benefit was found for periodontal therapy after 4 months in this study; trends in some results were in favour of periodontal treatment.

Abstract
A hypertension screening project was performed jointly at a dental clinic and a primary health care centre. In this report the hypothesis that there is an association between high diastolic blood pressure and deep periodontal pockets was tested. A total of 1,239 consecutive patients aged 35-65 years had their blood pressure measured before the dental examination or had a known hypertension. Information on medical history and tobacco use was obtained by interview and dental status was recorded. Fifty-four subjects had known hypertension and 141 had previously unknown diastolic blood pressure >90 mmHg (cases). For each case an age, sex and tobacco-use matched referent was chosen from those with diastolic blood pressure < or =90 mmHg. Significantly more cases than referents had periodontal pockets > or = 5 millimeters deep. In multivariate analyses the prevalence of deep periodontal pockets was associated with blood pressure status also after adjustment for the small differences between the groups in age, sex, tobacco use and number of teeth. In conclusion there was an association between diastolic blood pressure and prevalent deep periodontal pockets. Whether the relationship is a causal one remains to be explored. Screening for high blood pressure at regularly visits at the dental clinic may give the dental care a new important role in the public health field.

Abstract
For decades, physicians and dentists have paid close attention to their own respective fields, specializing in medicine pertaining to the body and the oral cavity, respectively. However, recent findings have strongly suggested that oral health may be indicative of systemic health. Currently, this gap between allopathic medicine and dental medicine is quickly closing, due to significant findings supporting the association between periodontal disease and systemic conditions such as cardiovascular disease, type 2 diabetes mellitus, adverse pregnancy outcomes, and osteoporosis. Significant effort has brought numerous advances in revealing the etiological and pathological links between this chronic inflammatory dental disease and these other conditions. Therefore, there is reason to hope that the strong evidence from these studies may guide researchers towards greatly improved treatment of periodontal infection that would also ameliorate these systemic illnesses. Hence, researchers must continue not only to uncover more information about the correlations between periodontal and systemic diseases but also to focus on positive associations that may result from treating periodontal disease as a means of ameliorating systemic diseases.

Abstract
Introduction: Over the past decade, there has been an emerging interest in the interrelationship between systemic conditions and oral health. Diabetes is perhaps one of the best documented conditions that have been closely linked with periodontal disease. This paper reviews the role of diabetes as a risk factor in periodontal disease. The treatment implications in the management of periodontal disease as an integral component of diabetes care is also discussed in light of the current understanding of the pathogenesis of these 2 chronic conditions.
Materials and Methods: Epidemiological, clinical and laboratory studies examining the relationship between diabetes and periodontal diseases were selected from both medical and dental journals.
Results: The severity of periodontal destruction has been shown to be related to the direct and indirect effects of glycaemic control, with other factors also being implicated. Although some studies have pointed towards a bi-directional relationship between glycaemic control and periodontal health, it is still not clear if improvement in periodontal health could lead to improved metabolic control.
Conclusion: Diabetes and periodontal disease are closely related in many ways, though the effect of periodontal disease on diabetes control remain to be determined, with larger intervention studies. In light of the increasing evidence of the relationship between diabetes and periodontal disease, management of oral health should form an integral part of diabetes management.
