Abstract
SUMMARY Heme (iron protoporphyrin IX, FePPIX) is the main source of iron and PPIX for host-associated pathogenic bacteria, including members of the Bacteroidota (formerly Bacteroidetes) phylum. Porphyromonas gingivalis, a keystone oral pathogen, uses a unique heme uptake (Hmu) system, comprising a hemophore-like protein, designated as the first member of the novel HmuY family. Compared to classical, secreted hemophores utilized by Gram-negative bacteria or near-iron transporter domain-based hemophores utilized by Gram-positive bacteria, the HmuY family comprises structurally similar proteins that have undergone diversification during evolution. The best characterized are P. gingivalis HmuY and its homologs from Tannerella forsythia (Tfo), Prevotella intermedia (PinO and PinA), Bacteroides vulgatus (Bvu), and Bacteroides fragilis (BfrA, BfrB, and BfrC). In contrast to the two histidine residues coordinating heme iron in P. gingivalis HmuY, Tfo, PinO, PinA, Bvu, and BfrA preferentially use two methionine residues. Interestingly, BfrB, despite conserved methionine residue, binds the PPIX ring without iron coordination. BfrC binds neither heme nor PPIX in keeping with the lack of conserved histidine or methionine residues used by other members of the HmuY family. HmuY competes for heme binding and heme sequestration from host hemoproteins with other members of the HmuY family to increase P. gingivalis competitiveness. The participation of HmuY in the host immune response confirms its relevance in relation to the survival of P. gingivalis and its ability to induce dysbiosis not only in the oral microbiome but also in the gut microbiome or other host niches, leading to local injuries and involvement in comorbidities.

A randomized case-control study. BMC Oral Health 2023; 23:544. [PMID: 37553617 PMCID: PMC10410947 DOI: 10.1186/s12903-023-03272-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 07/31/2023] [Indexed: 08/10/2023] Open
Abstract
OBJECTIVES To assess if the results following intake of a diet using an Okinawan-based Nordic diet (OBND) over one month differs in endocrinological, periodontal clinical outcome, and serum cytokine levels compared to a standard hospital care diet in individuals with diabetes type 2 (T2D) (control group). BACKGROUND Scientific evidence suggests that the use of diet for individuals with T2D may be beneficial. METHODS Participating individuals with T2D were randomly assigned to a test (OBND) (n = 14), or control group (n = 16). Anthropometric data, blood glucose levels, HbA1c levels, lipids, serum inflammation markers (CRP, and a routine panel of 24 cytokines), blood pressure, gingival bleeding on probing (BOP), probing pocket depths (PPD), and clinical attachment levels (CAL) were studied. RESULTS Statistical analyses of baseline study data failed to demonstrate study group differences. The mean weight reduction was greater in the OBND group (4.1 kg) versus the control group (1.3 kg) (p < 0.01). The reduction in BMI was 1.4 kg/m2 in OBND (p < 0.001) and 0.5 kg/m2 in the control group, respectively (p < 0.01). Diastolic and systolic blood pressure reductions were greater in the OBND group than in the control group (p < 0.01). Periodontal study parameters (BOP % scores) and (PPD values) decreased (p < 0.001) overall with no between group differences. The OBND resulted in reduction of serum levels of IFNγ, Eotaxin IL-9, IP10,IL17a, MCP-1,m and PDFBB compared to the control diet. CONCLUSIONS A strict T2D- diet provides an association between reduction in serum HbA1c and BOP scores. Serum levels decreases in IFNγ, Eotaxin IL-9, IP-10, IL17a. MCP-1, and PDFBB were only found in the test group.

Abstract
Glycemic control appears to have a significant impact on the relationship between periodontitis and diabetes. The current study aimed to investigate the association between the stage of periodontitis and hemoglobin A1c (HbA1c) levels in patients considered to be normoglycemic. A total of 135 patients (100 females and 35 males) with no history of diabetes were included in the study. The mean age of the participants was 38.4 years old. All patients underwent a full-mouth periodontal examination. Periodontal diagnosis was determined according to the 2017 World Workshop on the Classification of Periodontal Disease. The glycemic state of the patients was assessed using a chair-side HbA1c analyzer. Ninety patients were diagnosed with periodontitis. Higher average HbA1c levels were associated with the different stages of periodontitis (p<0.01). Most of the non-periodontitis patients were in the non-diabetes group (67%), while most of the periodontitis patients were in the undiagnosed pre-diabetes group (47% of the stages I and II group, and 44% of the stages III and IV groups) (p<0.001). Periodontitis was found to be significantly associated with elevated glycated hemoglobin levels in patients not previously diagnosed with diabetes, and the elevation in HbA1c levels was more evident in patients with stage III and IV periodontitis.

Abstract
Epidemiologic evidence indicates that periodontitis is more frequent in patients with uncontrolled diabetes mellitus than in healthy controls, suggesting that it could be considered the "sixth complication" of diabetes. Actually, diabetes mellitus and periodontitis are two extraordinarily prevalent chronic diseases that share a number of comorbidities all converging toward an increased risk of cardiovascular disease. Periodontal treatment has recently been shown to have the potential to improve the metabolic control of diabetes, although long-term studies are lacking. Uncontrolled diabetes also seems to affect the response to periodontal treatment, as well as the risk to develop peri-implant diseases. Mechanisms of associations between diabetes mellitus and periodontal disease include the release of advanced glycation end products as a result of hyperglycemia and a range of shared predisposing factors of genetic, microbial, and lifestyle nature. This review discusses the evidence for the risk of periodontal and peri-implant disease in diabetic patients and the potential role of the dental professional in the diabetes-periodontal interface.

Abstract
Diabetes mellitus and periodontitis are two of the most common chronic diseases affecting the world's population, and they are intimately linked. For several years, in fact, it has been known that there is an interdependent relationship between the two diseases: Diabetes promotes the destruction of periodontal tissues, and periodontal disease negatively affects glycemic control. In relation to the control of dental plaque and oral dysbiosis responsible for periodontal disease, both nonsurgical and surgical therapy associated with proper home hygiene procedures have emerged as essential for good glycemic control. Moreover, several evidences suggest the essential role played by the control of periodontal disease in preventing the onset of the most common complications of diabetes: cardiovascular diseases, retinopathies, and other systemic diseases. The aim of this study is to update the current knowledge on the bi-univocal relationship between diabetes and periodontitis and the impact of therapy in the optimal management of these two disorders. From the information found in the literature, it has emerged that the correct treatment of periodontal disease in diabetic patients represents one of the main mechanisms and means currently established and valid to control periodontal disease and glucose metabolism and prevent the onset or development of diabetic complications.

Abstract
The non-enzymatic addition of glucose (glycation) to circulatory and tissue proteins is a ubiquitous pathophysiological consequence of hyperglycemia in diabetes. Given the high incidence of periodontitis and diabetes and the emerging link between these conditions, it is of crucial importance to define the basic virulence mechanisms employed by periodontopathogens such as Porphyromonas gingivalis in mediating the disease process. The aim of this study was to determine whether glycated proteins are more easily utilized by P. gingivalis to stimulate growth and promote the pathogenic potential of this bacterium. We analyzed the properties of three commonly encountered proteins in the periodontal environment that are known to become glycated and that may serve as either protein substrates or easily accessible heme sources. In vitro glycated proteins were characterized using colorimetric assays, mass spectrometry, far- and near-UV circular dichroism and UV–visible spectroscopic analyses and SDS-PAGE. The interaction of glycated hemoglobin, serum albumin and type one collagen with P. gingivalis cells or HmuY protein was examined using spectroscopic methods, SDS-PAGE and co-culturing P. gingivalis with human keratinocytes. We found that glycation increases the ability of P. gingivalis to acquire heme from hemoglobin, mostly due to heme sequestration by the HmuY hemophore-like protein. We also found an increase in biofilm formation on glycated collagen-coated abiotic surfaces. We conclude that glycation might promote the virulence of P. gingivalis by making heme more available from hemoglobin and facilitating bacterial biofilm formation, thus increasing P. gingivalis pathogenic potential in vivo.

Abstract
Oral diseases associated with systematic diseases as metabolic and vasculitic have been included in this paper. This will enhance our understanding of the salivary function in promoting healthy oral condition. The study investigates the effects of type I and type II diabetes mellitus in well-controlled diabetic patients, in addition to Behçet disease (BD) on saliva flow rate (SFR), pH, the decay, missing, and filled tooth (DMFT) index, glucose, and major earth-alkaline ions (Ca2+ and Mg2+) compared to healthy males and age-matched controls. Saliva samples were collected from 1403 male human subjects, distributed on 7 levels including 3 control groups, and analyzed. The symptoms and clinical observations were enrolled. A preprandial salivary glucose has illustrated statistically strong significant and positive correlations with HbA1c and blood glucose levels. TIDM saliva showed lower pH, SFR, and Ca2+ but higher Mg2+, caries risk, and poor metabolic control. These led to dysfunction of secretory capacity of salivary glands. TIIDM proved higher SFR, DMFT, and glucose than TIDM patients. DM oral calcium has decreased by age while magnesium sharply slopes at seniority. BD oral fluid is associated with lower glucose and minerals but noticeably with both higher pH and DMFT.

Abstract
In order to evaluate whether nonsurgical periodontal treatment with/without diode laser (DL) decontamination improves clinical parameters, the levels of IL-1β, IL-6, IL-8, intercellular adhesion molecule (ICAM), and vascular cell adhesion molecule (VCAM) in gingival crevicular fluid and metabolic control (HbA1c) in chronic periodontitis (CP) patients with diabetes mellitus type 2 (DM2). Sixty patients with DM2 and CP were randomly assigned into two groups to receive scaling and root planing (SRP, n = 30) or SRP followed by diode laser application (SRP + DL, n = 30). Clinical periodontal and gingival crevicular fluid (GCF) parameters were assessed at baseline, 1, and 3 months after periodontal treatment. HbA1c levels were evaluated at baseline and 3 months post-therapy. Total amounts of cytokines and molecules were analyzed by ELISA. Nonsurgical periodontal treatment with/without DL appeared to improve clinical, biochemical parameters, and glycemic control in DM2 patients (BMI < 25 kg/m(2)) with CP. The SRP + DL group provided better reductions in probing depth (PD) and clinical attachment level (CAL) parameters compared to the SRP group (P < 0.05). Significant reductions were found in the total amounts of GCF levels of IL-1, IL-6, IL-8, ICAM, and VCAM after treatment (P < 0.05). HbA1c levels decreased significantly at 3 months after treatment (P < 0.05). SRP + DL reduced HbA1c levels more significantly compared to SRP alone (0.41 vs. 0.22 %, P < 0.05). SRP, especially in combination with DL, shows improvement of glycemic control for DM2 patients with CP.

Abstract
PURPOSE Diabetes and periodontal disease are two common diseases with high prevalence rates. Recent evidence has shown a bidirectional relationship between diabetes and periodontitis. The aim of this study was to investigate the effects of nonsurgical periodontal therapy on glycemic control in type 2 diabetes mellitus patients. METHODS Sixty subjects aged 35-45 years with blood sugar controlled by oral hypoglycaemic agents were randomly divided equally among 3 groups: group A (scaling, mouthwash, and brushing), group B (mouthwash and brushing), and group C (brushing only). Glycated haemoglobin (HbA1c), fasting blood sugar (FBS), probing pocket depth (PPD), gingival index (GI), plaque index (PI), and the relevant drug history were recorded at baseline and after 3 months of intervention. Comparison of the mean difference among the variables was performed by parametric and nonparametric tests, which were further evaluated using multiple regression analysis. RESULTS The mean differences between the PPD, FBS, HbA1c, GI, and PI in groups A and B were found to be statistically significant (P<0.001). Multiple regression analysis in group A showed that out of all the independent variables, GI and frequency of drug administration independently (b=0.3761 and b=0.598) showed a significantly greater impact on HbA1c (R(2)=0.832, P<0.05). CONCLUSIONS Nonsurgical periodontal therapy can effectively decrease HbA1c levels in type 2 diabetes mellitus patients on medication.

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
UNLABELLED The relationship between diabetes mellitus and periodontal disease is not clear, even though studied intensively. From the available data, it seemed reasonable to believe that diabetics were more susceptible to periodontal disease than non.diabetics. AIM The present study was to clinically evaluate the relationship of diabetes mellitus with periodontal disease along with various parameters. MATERIALS AND METHODS Fifteen hundred patients with diabetes mellitus were examined. A thorough oral examination was carried out and relevant history was recorded for all the patients. RESULTS Results indicated that the prevalence of periodontal disease in diabetic patients was 86.8%. CONCLUSION It can be concluded that poorer the glycemic control, and longer the duration of diabetes, the greater will be the prevalence and severity of periodontal disease.

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
BACKGROUND The periodontal status and effects of non-surgical periodontal treatment in patients with type 2 diabetes mellitus and periodontal disease are assessed. METHODS One-hundred patients with type 2 diabetes (mean ± SD hemoglobin (Hb)A1c level: 7.3% ± 0.94%) and periodontal disease were recruited for this study. The group with moderate-to-severe periodontal disease included patients with >1 tooth with a probing depth (PD) ≥5 mm and >2 teeth with a clinical attachment loss (AL) ≥ 6mm, and the group with mild periodontal disease included patients with <1 affected tooth, and >2 affected with a clinical AL ≥ 6mm. Patients (28 patients in the mild group and 72 patients in the moderate-to-severe group) underwent non-surgical periodontal treatments. We analyzed differences in serum concentrations of metabolic parameters (glycated hemoglobin and low-density lipoprotein), inflammatory parameters (interleukin [IL]-1β and C-reactive protein [CRP]), and periodontal parameters between the two groups before treatment and at 3, 6, 9, and 12 months post-therapy. RESULTS Seventy-five patients with diabetes (21 patients in the mild group and 54 patients in the moderate-to-severe group) completed the study. Significant differences in the plaque index (PI), gingival index (GI), PD, and clinical AL at examination times were observed in the whole cohort (P <0.05). We observed significant differences in the PI, GI, and PD in the moderate-to-severe group (P <0.05), whereas there was only a significant difference in PD in the mild group (P <0.05) between baseline and 12 months post-treatment. Both groups experienced improved glycemic control, but the difference was insignificant. CRP and IL-1β levels were significantly different at examination times for the whole cohort (P <0.05). No significant positive association among metabolic and inflammatory parameters at 12 months post-therapy were found. CONCLUSION Non-surgical periodontal treatment improved and maintained the periodontal health of patients with well-controlled diabetes, but no significant reduction of metabolic parameters was observed over a 1-year period.

Abstract
BACKGROUND AND OBJECTIVE Several studies have shown that periodontitis can complicate the severity of diabetes by worsening the degree of glycemic control. The purpose of this study was to determine the effect of full-mouth tooth extraction on glycemic control among type 2 diabetic patients. MATERIAL AND METHODS A total of 58 patients with type 2 diabetes mellitus and advanced periodontitis who were requiring extraction of all remaining teeth were randomized consecutively into treatment (full-mouth tooth extraction) and control groups (no treatment). Eight patients were lost to follow-up or reported use of antibiotics, leaving 50 patients to be included in the analysis. All patients had all their remaining teeth in a hopeless condition. Relevant data were collected, and glycosylated hemoglobin (HbA(1c) ) and fasting blood glucose levels were measured at baseline and at follow-up times of 3 and 6 mo. RESULTS At baseline, the mean (SD) HbA(1c) level was 8.6% (1.24) in the treatment group and 7.7% (0.87) in the control group. In the treatment group, the mean HbA(1c) level decreased significantly from 8.6% at baseline to 7.4% after 3 mo of denture treatment, and continued to decrease to 7.3% after 6 mo. In the control group, the mean HbA(1c) decreased from 7.7% at baseline to 7.5% after 3 mo, and remained almost the same after 6 mo. After adjusting for the baseline HbA(1c) , the mean reduction in HbA(1c) after 3 mo in the treatment group [1.23% (0.79)] was significantly higher than the mean reduction in the control group [0.28% (0.87)]. CONCLUSION Full-mouth tooth extraction resulted in an improvement in glycemic control among diabetic patients. Large-scale multicentre clinical trials are needed to confirm the current evidence.

Abstract
Diabetes and periodontitis are chronic inflammatory disorders that contribute to each others' severity and worsen each others' prognosis. Studies have shown that patients with diabetes are at increased risk of developing periodontitis, and that diabetics with untreated periodontitis have more difficulty controlling serum glucose. Periodontal treatment that reduces gingival inflammation aids in the control of hyperglycemia. Periodontitis is accompanied by gingival bleeding and the production of an inflammatory exudate termed gingival crevicular fluid (GCF) that arises from the inflamed gingival tissues surrounding the teeth. GCF contains byproducts of connective tissue degradation, enzymes from host and bacterial cells, cytokines and other inflammatory mediators, and has been studied for screening blood glucose and for biomarkers of both diabetes and periodontitis. This review focuses on the inter-relationship between diabetes and periodontitis and the biomarkers common to both these diseases that may enable earlier detection, targeted preventive measures and individualized therapeutic intervention of these chronic conditions.

Abstract
BACKGROUND The purpose of this study was to evaluate and compare salivary concentrations of reduced, oxidized glutathione, uric acid, ascorbic acid, and total antioxidant capacity in subjects with diabetes and systemically healthy subjects with inflammatory periodontal disease. METHODS Sixteen patients with type 1 diabetes mellitus (DM), 25 patients with type 2 DM, and 24 systemically healthy patients, all with inflammatory periodontal disease, were recruited. Whole-saliva samples were obtained, and full-mouth clinical periodontal measurements, including plaque index, probing depth, gingival recession, clinical attachment level, and bleeding on probing, were recorded at six sites per tooth. Saliva flow rate and salivary levels of reduced and oxidized glutathione, vitamin C, uric acid, and total antioxidant capacity were determined. Data were analyzed statistically by non-parametric tests. RESULTS The subjects with type 2 DM had fewer teeth and more sites with probing depths >4 mm than the patients with type 1 DM (both P <0.01). The mean salivary reduced-glutathione concentration was lower in patients with type 1 DM than in the other two groups (both P <0.05). No significant differences in the salivary concentrations of the other antioxidants measured were found among the groups (P >0.05). Oxidized glutathione levels in the patients with type 1 DM were significantly lower than in the systemically healthy group (P = 0.007). In both groups with diabetes, salivary reduced-glutathione levels correlated positively with probing depth, and total antioxidant capacity correlated with salivary flow rate (P <0.01). CONCLUSION The decrease in salivary reduced-glutathione levels in patients with type 1 DM may have a role in periodontal tissue destruction by predisposing tissues to oxidative stress.

Abstract
BACKGROUND This study evaluated the clinical and metabolic effects of full-mouth scaling and root planing (FMSRP) compared to partial-mouth scaling and root planing (PMSRP) in patients with type 2 diabetes and chronic periodontitis, and it assessed the impact of the glycemic status on the clinical and metabolic response to periodontal therapy. METHODS In this clinical trial, 18 subjects with diabetes received FMSRP in a maximum of 24 hours, and 18 subjects received PMSRP in a maximum of 21 days. Visible plaque accumulation, bleeding on probing, suppuration, probing depth, clinical attachment level (CAL), and glycosylated hemoglobin (HbA1c) levels were obtained at baseline and at 3 and 6 months post-therapy. Baseline HbA1c values > or =9% and <9% defined subjects with poorly and better-controlled diabetes, respectively. RESULTS All clinical parameters improved after therapy (P <0.05). No significant differences were observed between treatment groups for clinical and metabolic parameters at any time (P >0.05). There were no changes in the HbA1c levels after therapy (P >0.05). No subject reported any adverse effects during the study. Individuals with better-controlled diabetes achieved a lower mean CAL at 6 months post-therapy, when FMSRP and PMSRP were evaluated together (P <0.05). CONCLUSIONS FMSRP and PMSRP were equally effective in treating chronic periodontitis in subjects with type 2 diabetes, without significant improvements in the glycemic control at 3 and 6 months. Considering the periodontal therapy as a whole (FMSRP plus PMSRP), subjects with better-controlled diabetes exhibited a benefit in CAL at 6 months compared to subjects with poorly controlled disease.

Abstract
BACKGROUND African Americans have a disproportionate burden of diabetes. Gullah African Americans are the most genetically homogeneous population of African descent in the United States, with an estimated European admixture of only 3.5%. This study assessed the previously unknown prevalence of periodontal disease among a sample of Gullah African Americans with diabetes and investigated the association between diabetes control and the presence of periodontal disease. METHODS Two hundred thirty-five Gullah African Americans with type 2 diabetes were included. Diabetes control was assessed by percentage of glycosylated hemoglobin (HbA1c) and divided into three categories: well controlled, <7%; moderately controlled, 7% to 8.5%; and poorly controlled, >8.5%. Participants were categorized as healthy (no clinical attachment loss [AL] or bleeding on probing) or as having early periodontitis (clinical AL > or =1 mm in at least two teeth), moderate periodontitis (three sites with clinical AL > or =4 mm and at least two sites with probing depth [PD] > or =3 mm), or severe periodontitis (clinical AL > or =6 mm in at least two teeth and PD > or =5 mm in at least one site). Observed prevalences of periodontitis were compared to rates reported for the National Health and Nutrition Examination Survey (NHANES) studies. RESULTS All subjects had evidence of periodontal disease: 70.6% had moderate periodontitis and 28.5% had severe disease. Diabetes control was not associated with periodontal disease. The periodontal disease proportions were significantly higher than the reported national prevalence of 10.6% among African Americans without diabetes. CONCLUSION Our sample of Gullah African Americans with type 2 diabetes exhibited a higher prevalence of periodontal disease compared to African Americans, with and without diabetes, as reported in NHANES III and NHANES 1999-2000.

Abstract
Chronic adult periodontitis is a bacterially induced chronic inflammatory disease that destroys the connective tissue and bone that support teeth. Concepts of the specific mechanisms involved in the disease have evolved with new technologies and knowledge. Histopathologic observations of diseased human tissues were used previously to speculate on the causes of periodontitis and to describe models of pathogenesis. Experimental evidence later emerged to implicate bacterial plaque deposits as the primary factor initiating periodontitis. At the same time, specific bacteria and immunoinflammatory mechanisms were differentially implicated in the disease. In the mid-1990s, early insights about complex diseases, such as periodontitis, led to new conceptual models of the pathogenesis of periodontitis. Those models included the bacterial activation of immunoinflammatory mechanisms, some of which targeted control of the bacterial challenge and others that had adverse effects on bone and connective tissue remodeling. Such models also acknowledged that different environmental and genetic factors modified the clinical phenotype of periodontal disease. However, the models did not capture the dynamic nature of the biochemical processes, i.e., that innate differences among individuals and changes in environmental factors may accelerate biochemical changes or dampen that shift. With emerging genomic, proteomic, and metabolomic data and systems biology tools for interpreting data, it is now possible to begin describing the basic elements of a new model of pathogenesis. Such a model incorporates gene, protein, and metabolite data into dynamic biologic networks that include disease-initiating and -resolving mechanisms. This type of model has a multilevel framework in which the biochemical networks that are regulated by innate and environmental factors can be described and the interrelatedness of networks can be captured. New models in the next few years will be merely frameworks for integrating key knowledge as it becomes available from the "-omics" technologies. However, it is possible to describe some of the key elements of the new models and discuss distinctions between the new and older models. It is hoped that improved conceptual models of pathogenesis will assist in focusing new research and speed the translation of new data into practical applications.

Abstract
BACKGROUND Diabetes is a major risk factor for the development of periodontal disease in certain populations. The prevalence of type 2 diabetes is increased in Hispanic Americans, but its impact on the extent and severity of periodontal disease in this population has not been determined. METHODS Sixty-three Hispanic Americans, aged 33 to 72 years, from South Texas were grouped based on the presence or absence of type 2 diabetes. Past medical histories, including smoking, were obtained. Periodontal status was evaluated by measuring probing depth (PD), clinical attachment level (CAL), plaque, bleeding on probing, visual gingival inflammation, and calculus. RESULTS Type 2 diabetes was associated frequently with major medical complications in this population. Diabetes was associated with significantly more calculus formation and tooth loss and an increased extent and severity of periodontitis. Subjects with diabetes had nearly three times the mean CAL and frequency of PD >6 mm than subjects without diabetes and nearly twice the frequency of moderate to advanced attachment loss (> or =3 mm). Smoking and diabetes had significant independent effects on mean CAL and the frequency of deep pockets. Diabetes and smoking combined were associated with a significantly higher frequency of sites with CAL > or =3 mm compared to healthy non-smokers, healthy smokers, and non-smokers with diabetes. CONCLUSIONS Hispanic Americans with type 2 diabetes had more supra- and subgingival calculus, an increased extent and severity of periodontal destruction, and an increased frequency of tooth loss due to periodontitis. An additive/synergistic contribution of type 2 diabetes and smoking for increasing the extent of periodontal disease was observed.

Abstract
OBJECTIVES To evaluate if type 2 diabetes mellitus increase gingival crevicular fluid (GCF) levels of prostaglandin E(2) (PGE(2)), interleukin-1beta (IL-1beta), tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor-2 (PAI-2). DESIGN AND METHODS Seventeen type 2 diabetic patients with periodontal disease (DM), 17 otherwise healthy periodontally diseased patients (PD) and 17 systemically and periodontally healthy control subjects (H) were enrolled. Clinical periodontal measurements were recorded at six sites/tooth. GCF samples were analyzed by ELISA. Data were tested by statistical tests. RESULTS DM group revealed lower IL-1beta levels than PD group (p<0.01). PGE(2), t-PA and PAI-2 levels were similar in DM and PD groups (p>0.05). PGE(2), t-PA levels were higher in DM and PD groups than H group (p<0.05). PAI-2 level was higher in DM group than H group (p<0.05). GCF total amount of PGE(2) in DM group exhibited significant correlations with all clinical periodontal measurements (p<0.05). CONCLUSION Type 2 diabetes in this study seems not to increase GCF levels of the evaluated inflammatory mediators.

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
AIM The aim of this study was to investigate the relationship between markers of metabolic control and inflammation and periodontal disease parameters in patients with diabetes. MATERIAL & METHODS One hundred and eighty one adult patients with diabetes attending treatment at two diabetes centres were invited to participate in the study. Periodontal examination included full-mouth assessment for probing depths and bleeding on probing (BOP). Blood analyses were carried out for glycated haemoglobin, (HbA1c), high-sensitivity C reactive protein, (hsCRP) and lipid profile comprising total cholesterol, low-density lipoprotein cholesterol (LDL chol), high-density lipoprotein cholesterol (HDL chol) and triglycerides. RESULTS Upon multivariate analysis, periodontal disease severity in terms of increased percentage of BOP and mean percentage of sites with probing depths > or = 5 mm were found to be associated with inadequate glycaemic control as measured by HbA1c (p<0.01). HsCRP was also found to be a significant predictor for mean percentage of sites with probing depths > or = 5 mm (p<0.05). After controlling for age, gender, smoking habits and number of teeth, positive correlations were found between HbA1c and percentage sites with probing depths > or = 5 mm, percentage sites BOP, total cholesterol, LDL chol and triglycerides (p<0.05). Using the adjusted differences, subjects with acceptable glycaemic control (HbA1c < 8%) showed a lower percentage of sites with BOP and probing depths > or = 5 mm (p<0.05) when compared with those having inadequate glycaemic control. There was also a trend towards lower blood cholesterol in the well-controlled group. CONCLUSION The level of glycaemic control as measured by HbA1c emerged as the most consistent risk factor associated with the extent and severity of periodontal disease in this study cohort.

Abstract
It has been demonstrated that diabetes mellitus (DM) may have an inductive effect on the vascular endothelial growth factor (VEGF) levels of periodontium during periodontal disease. The aim of this study is to confirm this phenomenon, investigating whether it is also valid for diabetic periodontitis patients under good metabolic control. Sixteen type II DM patients, all with a glycosylated hemoglobin (HbA1c) value less than 7 (test), and 15 systemically healthy (control) chronic periodontitis patients were included in the study. The VEGF concentrations in the gingival supernatants and gingival crevicular fluid (GCF) samples of the study groups were measured by enzyme-linked immunosorbent assay. The data were analyzed by Student's t test in statistical means. The VEGF levels were significantly higher in the gingival supernatants of the test group (55.89 +/- 8.11 pg/ml) than that of the control group (24.81 +/- 2.04 pg/ml; p < 0.01). However, there was no statistically significant difference in the VEGF levels of GCF between the study groups (38.96 +/- 4.89 pg/ml in the test and 32.20 +/- 4.02 pg/ml in the control group; p > 0.05). Our study confirms that DM affects the VEGF levels of periodontal soft tissues in periodontal disease, and our results also suggest that this effect may not be influenced by the metabolic control of DM.

Abstract
BACKGROUND The purpose of this review is to provide the reader with practical knowledge concerning the relationship between diabetes mellitus and periodontal diseases. Over 200 articles have been published in the English literature over the past 50 years examining the relationship between these two chronic diseases. Data interpretation is often confounded by varying definitions of diabetes and periodontitis and different clinical criteria applied to prevalence, extent, and severity of periodontal diseases, levels of glycemic control, and complications associated with diabetes. METHODS This article provides a broad overview of the predominant findings from research published in English over the past 20 years, with reference to certain "classic" articles published prior to that time. RESULTS This article describes current diagnostic and classification criteria for diabetes and answers the following questions: 1) Does diabetes affect the risk of periodontitis, and does the level of metabolic control of diabetes have an impact on this relationship? 2) Do periodontal diseases affect the pathophysiology of diabetes mellitus or the metabolic control of diabetes? 3) What are the mechanisms by which these two diseases interrelate? and 4) How do people with diabetes and periodontal disease respond to periodontal treatment? CONCLUSIONS Diabetes increases the risk of periodontal diseases, and biologically plausible mechanisms have been demonstrated in abundance. Less clear is the impact of periodontal diseases on glycemic control of diabetes and the mechanisms through which this occurs. Inflammatory periodontal diseases may increase insulin resistance in a way similar to obesity, thereby aggravating glycemic control. Further research is needed to clarify this aspect of the relationship between periodontal diseases and diabetes.

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.

Abstract
OBJECTIVES Polymorphonuclear neutrophil (PMN) dysfunction is associated with diabetes. We examined the gingival crevicular fluid (GCF) beta-glucuronidase (BG) and interleukin-8 (IL-8) levels of periodontitis patients with and without type 2 diabetes mellitus (DM). MATERIAL AND METHODS Forty five adults with type 2 DM and 32 adults without DM, both with chronic periodontitis were enrolled. GCF was collected from eight posterior sites in each quadrant, and periodontal parameters were recorded. GCF was assayed for IL-8 by ELISA and BG by a fluorometric assay. RESULTS GCF IL-8 was positively correlated with probing depth (PD), and GCF BG but not clinical attachment level (CAL), bleeding on probing (BOP), or plaque index (PI). In contrast, GCF BG was strongly correlated with each of the clinical measures of periodontal disease. Subjects with DM significantly lower levels of both BG (73.0+/-44.8 versus 121.9+/-84.6 pg/sample; p=0.002) and IL-8 (32.1+/-33.1 versus 90.8+/-83.2 pg/sample; p<0.0001) even after adjustments for age, gender, PD, CAL, BOP, and PI. Neither BG nor IL-8 was correlated with HbA1c levels in subjects with DM. CONCLUSION These data suggest that an inadequate local response by PMN, partially explained by an altered chemokine gradient, may contribute to periodontal disease in patients with type 2 DM.

Abstract
BACKGROUND Several studies have found correlations between diabetes and an increased prevalence of periodontitis. OBJECTIVE To analyse, in a group of subjects with type 2 diabetes (T2D), (i) the association between medical characteristics and severe periodontal disease and (ii) dental care habits and knowledge of oral health. METHODS One hundred and ninety-one subjects with T2D were examined. Based on assessment of marginal bone height in panoramic radiographs, two periodontal subgroups were identified: one periodontally diseased (PD+) and one periodontally healthy (PD-) group. All subjects completed a questionnaire about their medical and oral health. RESULTS Twenty per cent of the subjects were classified as PD+. This was verified by clinical parameters. PD+ individuals had higher haemoglobin A1c (HbA1c) levels (p=0.033) and higher prevalences of cardiovascular complications (p=0.012). They were also less likely to be of Scandinavian origin (p=0.028) and more likely to smoke (p<0.001) than the PD- group. The PD+ group rated their oral health as poor (p<0.0001) and believed that T2D had an influence on their oral status (p<0.0001). CONCLUSION The best predictor for severe periodontal disease in subjects with T2D is smoking followed by HbA1c levels. T2D subjects should be informed about the increased risk for periodontal disease when suffering from T2D.

Abstract
BACKGROUND This meta-analysis was conducted to assess the association between diabetes mellitus and periodontal diseases by comparing the extent and severity of periodontal diseases between diabetics and nondiabetics. METHODS A literature search was performed using MEDLINE database for published studies from January 1970 through October 2003 with manual search for references in relevant studies. This meta-analysis was based on 18 comparative cross-sectional studies, three prospective cohort studies and baseline data of two clinical trials that compared oral hygiene, gingival and periodontal status between diabetics and nondiabetics. Heterogeneity was obvious among included studies; therefore, the analysis using random-effects model was conducted. RESULTS This study demonstrated that diabetics had significantly worse oral hygiene as measured by the average of plaque index (P1I), higher severity of gingival disease as measured by the average of gingival index (GI) and higher severity of periodontal disease as measured by the average of probing pocket depth (PPD) and clinical attachment loss (CAL). However, diabetics had similar extent of oral hygiene, gingival and periodontal disease as measured by percentages of surfaces or sites with specific scores of P1I, GI, bleeding on probing (BOP), PPD and CAL. CONCLUSIONS Diabetics had a significantly higher severity but the same extent of periodontal disease than nondiabetics.

Abstract
AIMS To assess the potential impact of the control of subject-based modifiable risk factors on periodontitis. BACKGROUND Cross-sectional and longitudinal data from epidemiological research indicate that risk factors can be identified and, if modified, may improve both periodontal conditions and the outcome of treatment. MATERIAL AND METHODS A search was conducted to identify factors involved in the etiology and pathogenesis of periodontal diseases. The factors identified were separated into modifiable and non-modifiable, and control of the subject-based modifiable risk factors were further analyzed. RESULTS The analysis was limited to the influence of the control of the remaining modifiable subject-based risk factors. It was observed that most of the subject related risk factors were hitherto not validated in controlled intervention studies. Therefore, the evidence for the efficacy of risk factor control had to be based on results from cohort studies. While the control of most of the modifiable risk factors for periodontitis was not tested, some evidence suggested that smoking cessation may retard the progression of periodontitis. CONCLUSIONS Although only limited evidence was available, it appeared reasonable to suggest that second to the removal of the bacterial biofilm, smoking cessation was the most important measure in the management of periodontitis.

Abstract
OBJECTIVES The aim of the present study was to investigate the effect of improved periodontal health on metabolic control in type 2 diabetes mellitus (DM) patients. MATERIAL AND METHODS Fourty-four patients with type 2 DM were selected. Subjects were randomly assigned into two groups. DATA COLLECTION Plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment levels (CALs), gingival recession (GR) and bleeding on probing (BOP) were recorded at baseline at 1st and 3rd months. Fasting plasma glucose (FPG), 2-h post-prandial glucose (PPG), glycated haemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), HDL-cholesterol, LDL-cholesterol and microalbuminure were analysed at baseline, 3 months following the periodontal therapy. The treatment group received full-mouth scaling and root planing whereas the control group received no periodontal treatment. RESULTS A statistically significant effect could be demonstrated for PI, GI, PPD, CAL and BOP for the treatment group. HbA1c levels in the treatment group decreased significantly whereas the control group showed a slight but insignificant increase for this parameter. CONCLUSIONS The results of our study showed that non-surgical periodontal treatment is associated with improved glycaemic control in type 2 patients and could be undertaken along with the standard measures for the diabetic patient care.

Abstract
OBJECTIVE To monitor clinical and microbiological changes during experimental gingivitis in type 1 diabetics and non-diabetics. MATERIALS AND METHODS Nine type 1 diabetics with good/moderate metabolic control and nine age-gender matched non-diabetics were recruited. Probing pocket depths in all subjects did not exceed 4 mm and none were affected by attachment loss. According to the original model, an experimental 3-week plaque accumulation resulting in experimental gingivitis development and a subsequent 2-week period of optimal plaque control were staged. Subgingival plaque samples were collected at days 0, 21 and 35 from one site per quadrant, pooled and analysed using checkerboard DNA-DNA hybridization. RESULTS Diabetics (mean age 25.6+/-5.8 standard deviation (SD), range 16-35 years) had a mean HbA1c level of 8.1+/-0.7% (SD), while non-diabetics (mean age 24.8+/-5.7 (SD), range 15-36 years) were metabolically controlled (HbA1c< or =6.5%). Between Days 0, 21 and 35, no statistically significant differences in mean plaque and gingival index scores were observed between diabetics and non-diabetics. At days 7 and 21, however, diabetics showed statistically significantly higher percentages of sites with gingival index scores > or =2 compared with non-diabetics. Mean DNA probe counts of the red and orange complex species increased significantly (p<0.05) between days 0 and 21 and decreased significantly (p<0.05) between days 21 and 35 in both groups. CONCLUSION Both diabetics and non-diabetics react to experimental plaque accumulation with gingival inflammation. Type 1 diabetics, however, develop an earlier and higher inflammatory response to a comparable bacterial challenge.

Abstract
BACKGROUND Patients with diabetes have increased incidence and severity of periodontal disease not accounted for by differences in the subgingival microbial infection. Poor glycemic control has been consistently associated with periodontal disease severity. Also, recent evidence suggests that hyperglycemia may induce inflammatory cytokine production. Few studies, however, have examined local biochemical measures of periodontal inflammation in patients with type 2 diabetes. The aim of this study was to determine whether glycemic control was related to gingival crevicular fluid (GCF) levels of interleukin-1beta (IL-1beta). METHODS GCF samples were collected from 45 patients with type 2 diabetes and untreated chronic periodontitis. Plaque index (PI), bleeding on probing (BOP), probing depth (PD), and attachment level (AL) were recorded at six sites per tooth. IL-1beta levels were determined from individual GCF samples by enzyme-linked immunoabsorbent assay (ELISA). Individual site and mean patient values were calculated. Glycated hemoglobin (HbA1c) levels were measured from anticoagulated whole blood using an automated affinity chromatography system. Serum glucose was also determined. RESULTS Clinical periodontal measures (PD, AL, BOP) and measures of glycemic control (HbA1c, random glucose) were significantly correlated with GCF IL-1beta. Patients with greater than 8% HbA1c had significantly higher mean GCF IL-1beta levels than patients with less than 8% HbA1c. In a multivariate model adjusting for age, gender, PD, AL, BOP, and PI, HbA1c and random glucose were independent predictors of high GCF IL-1beta. CONCLUSIONS Poor glycemic control is associated with elevated GCF IL-1beta. These data are consistent with the hypothesis that hyperglycemia contributes to an heightened inflammatory response, and suggests a mechanism to account for the association between poor glycemic control and periodontal destruction.

Abstract
BACKGROUND The aim of this study was to determine whether detectable periodontal destruction and alterations in the salivary status were present with duration of diabetes in children with type 1 insulin-dependent diabetes mellitus (type 1 DM) as compared to healthy controls. METHODS Sixteen newly diagnosed children with DM (group 1), 16 children with type 1 DM of long duration (group 2), and 16 healthy children (group 3) participated in the study. Periodontal health was assessed by plaque index, gingival index, bleeding on probing, and periodontal probing depths. The flow rate, pH, buffering capacity, and peroxidase activities of stimulated saliva were determined. The data were analyzed by Kruskall-Wallis, Student t test, and Pearson's correlation analysis. RESULTS The mean values for fasting blood glucose levels for the diabetic groups were significantly higher than for the controls. The mean values for salivary buffering capacities and salivary pH from the diabetic groups were significantly lower than for the controls. The plaque index values for the diabetic groups were significantly higher than for the controls. The mean gingival index value for group 1 was significantly lower than for group 2. The mean periodontal probing depths for group 1 were similar to those of the non-DM controls, but the mean periodontal probing depths for group 2 were significantly greater than for both the non-DM controls and group 1. Group 1 had significantly greater bleeding on probing scores than did the other groups (P < 0.05). CONCLUSION The glycemic status of the diabetic subjects affects the periodontal probing depths, salivary pH, buffering capacity, and peroxidase activity.

Abstract
Effects of diabetes on alveolar bone remodelling were assessed by quantitative histology and a chronological lead-labelling technique. Experimental diabetes was induced by a single dose of 40 mg/kg of streptozotocin. Remodelling of the alveolar wall surrounding the root of mandibular first molar was studied in control rats fed ad libitum, and in diabetic and insulin-treated diabetic rats 24 days after the induction of diabetes. The volumes of bone formation on the mesial side of the alveolar wall were evaluated over a 10-day period by chronological lead-labelling and computer image analysis. For a histometric measure of bone-resorption, the number of osteoclasts along the distal surface of the alveolar wall was counted. The volume of bone formed and the number of osteoclasts were significantly lower in the diabetic rats than in the controls, but insulin treatment of diabetic rats normalised these histomorphometric measures of bone turnover. These results demonstrate that streptozotocin-induced diabetes mellitus reduces the rate of bone turnover in the alveolar wall surrounding the root, which reduction is corrected by treatment with insulin.

Abstract
OBJECTIVE We investigated the association between glycemic control of type 2 diabetes mellitus (type 2 DM) and severe periodontal disease in the US adult population ages 45 years and older. METHODS Data on 4343 persons ages 45-90 years from the National Health and Nutrition Examination Study III were analyzed using weighted multivariable logistic regression. Severe periodontal disease was defined as 2 + sites with 6 + mm loss of attachment and at least one site with probing pocket depth of 5 + mm. Individuals with fasting plasma glucose > 126 mg/dL were classified as having diabetes; those with poorly controlled diabetes (PCDM) had glycosylated hemoglobin > 9% and those with better-controlled diabetes (BCDM) had glycosylated hemoglobin <or= 9%. Additional variables evaluated in multivariable modeling included age, ethnicity, education, gender, smoking status, and other factors derived from the interview, medical and dental examination, and laboratory assays. RESULTS Individuals with PCDM had a significantly higher prevalence of severe periodontitis than those without diabetes (odds ratio = 2.90; 95% CI: 1.40, 6.03), after controlling for age, education, smoking status, and calculus. For the BCDM subjects, there was a tendency for a higher prevalence of severe periodontitis (odds ratio = 1.56; 95% CI: 0.90, 2.68). CONCLUSION These results provide population-based evidence to support an association between poorly controlled type 2 diabetes mellitus and severe periodontitis.

Abstract
This review evaluates evidence for a bidirectional relationship between diabetes and periodontal diseases. A comprehensive Medline search of the post-1960 English language literature was employed to identify primary research reports of relationships between diabetes and periodontal diseases. Reports included in the review on the adverse effects of diabetes on periodontal health (DM-->PD) were restricted to those comparing periodontal health in subjects with and without diabetes. Review of adverse affects of periodontal infection on glycemic control included reports of periodontal treatment studies and follow-up observational studies in which changes in glycemic control could be assessed. Observational studies reporting DM-->PD provided consistent evidence of greater prevalence, severity, extent, or progression of at least one manifestation of periodontal diseases in the large majority of reports (supportive evidence in 44/48 total reviewed; 37/41 cross-sectional and 7/7 cohort). Additionally, there were no studies reviewed with superior design features to refute this association. Treatment studies provided direct evidence to support periodontal infection having an adverse, yet modifiable, effect on glycemic control. However, not all investigations reported an improvement in glycemic control after periodontal treatment. Additional evidence to support the effect of severe periodontitis on increased risk for poorer glycemic control comes from 2 follow-up observational studies. The evidence reviewed supports viewing the relationship between diabetes and periodontal diseases as bidirectional. Further rigorous, systematic study is warranted to establish that treating periodontal infections can be influential in contributing to glycemic control management and possibly to the reduction of the burden of complications of diabetes mellitus.

Abstract
Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life. One of these complications is periodontal disease (periodontitis). Periodontitis is much more than a localized oral infection. Recent data indicate that periodontitis may cause changes in systemic physiology. The interrelationships between periodontitis and diabetes provide an example of systemic disease predisposing to oral infection, and once that infection is established, the oral infection exacerbates systemic disease. In this case, it may also be possible for the oral infection to predispose to systemic disease. In order to understand the cellular/molecular mechanisms responsible for such a cyclical association, one must identify common physiological changes associated with diabetes and periodontitis that produce a synergy when the conditions coexist. A potential mechanistic link involves the broad axis of inflammation, specifically immune cell phenotype, serum lipid levels, and tissue homeostasis. Diabetes-induced changes in immune cell function produce an inflammatory immune cell phenotype (upregulation of proinflammatory cytokines from monocytes/polymorphonuclear leukocytes and downregulation of growth factors from macrophages). This predisposes to chronic inflammation, progressive tissue breakdown, and diminished tissue repair capacity. Periodontal tissues frequently manifest these changes because they are constantly wounded by substances emanating from bacterial biofilms. Diabetic patients are prone to elevated low density lipoprotein cholesterol and triglycerides (LDL/TRG) even when blood glucose levels are well controlled. This is significant, as recent studies demonstrate that hyperlipidemia may be one of the factors associated with diabetes-induced immune cell alterations. Recent human studies have established a relationship between high serum lipid levels and periodontitis. Some evidence now suggests that periodontitis itself may lead to elevated LDL/TRG. Periodontitis-induced bacteremia/endotoxemia has been shown to cause elevations of serum proinflammatory cytokines such as interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), which have been demonstrated to produce alterations in lipid metabolism leading to hyperlipidemia. Within this context, periodontitis may contribute to elevated proinflammatory cytokines/serum lipids and potentially to systemic disease arising from chronic hyperlipidemia and/or increased inflammatory mediators. These cytokines can produce an insulin resistance syndrome similar to that observed in diabetes and initiate destruction of pancreatic beta cells leading to development of diabetes. Thus, there is potential for periodontitis to exacerbate diabetes-induced hyperlipidemia, immune cell alterations, and diminished tissue repair capacity. It may also be possible for chronic periodontitis to induce diabetes.
