Combined association of oral and skeletal muscle health with type 2 diabetes mellitus among community-dwelling older adults in Japan: a cross-sectional study. J Rural Med 2022; 17:67-72. [PMID: 35432640 PMCID: PMC8984617 DOI: 10.2185/jrm.2021-042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2021] [Accepted: 01/04/2022] [Indexed: 11/27/2022] Open
Abstract
Objective: Although oral health and skeletal muscle status are known to be
risk factors for type 2 diabetes mellitus (T2DM), there is limited information on their
combined effects among community-dwelling older adults. The purpose of this study was to
investigate the association between oral health and skeletal muscle status among older
adults with T2DM in Japan. Participants and Methods: This cross-sectional study included data from
individuals aged ≥60 years. T2DM was defined as a glycosylated hemoglobin A1c level ≥48
mmol/mol (≥6.5%) or the use of hypoglycemic agents. For oral health status, dental
hygienists assessed the number of teeth (NT) and masticatory function (MF). Skeletal
muscle status was assessed using skeletal muscle mass index (SMI) and handgrip strength
(HGS). Logistic regression analysis examined T2DM in nine-category combinations of oral
health status (each of the three categories in NT and MF) and skeletal status (each of the
three categories in SMI and HGS). Results: T2DM was prevalent in 83 participants (16.4%) and was significantly
associated with low NT and SMI (odds ratio [OR] = 5.93, 95% confidence interval [CI]:
1.37–25.73) and low MF and SMI (OR = 4.48, 95% CI: 1.23–16.35) compared to high NT and SMI
and high MF and SMI, respectively. Conclusion: Our findings indicate that low muscle mass with tooth loss or
masticatory dysfunction is associated with T2DM among community-dwelling older adults.
This suggests that maintaining oral health and muscle mass may be an effective strategy
for the prevention of T2DM.

The effect of orthodontic treatment on the periodontium and soft tissue esthetics in adult patients. Clin Exp Dent Res 2021; 8:410-420. [PMID: 34494383 PMCID: PMC8874061 DOI: 10.1002/cre2.480] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 07/05/2021] [Accepted: 07/08/2021] [Indexed: 11/15/2022] Open
Abstract
Objective Most patients seek orthodontic treatment to achieve an esthetic outcome. Orthodontic treatment has possible negative sequelae. The aim of this study is to assess these possible effects on the periodontium and tissue esthetics. Methods One hundred fifty‐six patients who have completed orthodontic treatment at Jordan University of Science and Technology clinics were recruited. They were divided into extraction and nonextraction subgroups. Another 155 patients never undergoing orthodontic treatment were assessed. The height of papilla, width of keratinized gingiva, gingival recession, degree of tooth display, smile line, crestal bone level, and proximal caries were assessed. Chi‐ square test was used for categorical/discrete variables while independent t‐test was used for continuous variables. The level of significance was set at (p ≤ 0.05). Results The mean age was 22 years with no significant difference between the groups. There was a significant difference between “ortho” and “nonortho” groups in tooth display and keratinized gingiva (p = 0.006 and <0.001, respectively). The overall crestal bone level, smile line, recession, and papilla fill did not show any significant differences (p = 0.200, 0.067, 0.120, and 0.066, respectively). The crestal bone level in the upper and lower anterior segments was significantly lower in the “ortho” treated group compared to the “nonortho” treated group (p = 0.002 and 0.005, respectively). A significant difference between “extraction” and “nonextraction” groups was in the width of keratinized gingiva (p = 0.003) and the number of teeth displayed (p < 0.001). Despite reaching statistical significance these differences are not necessarily of clinical significance. Conclusion Orthodontic treatment clearly affects the periodontal tissues; however, the detrimental effects appear to be minimal. Patients with history of orthodontic treatment might have lower crestal bone levels at certain sites and this should not be confused with periodontal disease.

Abstract
This Perspective provides a brief summary of the scientific evidence for the often two-way links between hyperglycemia, including manifest diabetes mellitus (DM), and oral health. It delivers in a nutshell examples of current scientific evidence for the following oral manifestations of hyperglycemia, along with any available evidence for effect in the opposite direction: periodontal diseases, caries/periapical periodontitis, tooth loss, peri-implantitis, dry mouth (xerostomia/hyposalivation), dysbiosis in the oral microbiome, candidiasis, taste disturbances, burning mouth syndrome, cancer, traumatic ulcers, infections of oral wounds, delayed wound healing, melanin pigmentation, fissured tongue, benign migratory glossitis (geographic tongue), temporomandibular disorders, and osteonecrosis of the jaw. Evidence for effects on quality of life will also be reported. This condensed overview delivers the rationale and sets the stage for the urgent need for delivery of oral and general health care in patient-centered transdisciplinary collaboration for early detection and management of both hyperglycemia and oral diseases to improve quality of life.

Number of teeth and masticatory function are associated with sarcopenia and diabetes mellitus status among community-dwelling older adults: A Shimane CoHRE study. PLoS One 2021; 16:e0252625. [PMID: 34077486 PMCID: PMC8172058 DOI: 10.1371/journal.pone.0252625] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 05/19/2021] [Indexed: 01/13/2023] Open
Abstract
Objectives We aimed to examine the number of teeth and masticatory function as oral health indices and clarify their roles in the pathogenesis of sarcopenia and diabetes mellitus in community-dwelling older adults. Subjects and methods This cross-sectional study was conducted with 635 older adults in Ohnan, Shimane Prefecture, in rural Japan. The number of teeth and masticatory function (measured by the number of gummy jelly pieces collected after chewing) were evaluated by dental hygienists. Sarcopenia status was assessed using handgrip strength, skeletal muscle index, calf circumference, and a possible sarcopenia diagnosis based on the Asian Working Group for Sarcopenia 2019. Diabetes mellitus status was defined as a hemoglobin A1c level ≥6.5% or self-reported diabetes. A multivariable logistic regression model was used to analyze the association between oral health, sarcopenia, and diabetes mellitus after adjusting for confounders. Results After adjusting for all confounders, logistic regression analysis showed that the number of remaining teeth was negatively associated with a low level of handgrip strength (odds ratio [OR], 0.961; 95% confidence interval [CI], 0.932–0.992) and possible sarcopenia (OR, 0.949; 95% CI, 0.907–0.992). Higher levels of masticatory function were also negatively associated with a low level of handgrip strength (OR, 0.965; 95% CI, 0.941–0.990) and possible sarcopenia (OR, 0.941; 95% CI, 0.904–0.979). Logistic regression analysis showed that the number of remaining teeth and a higher level of masticatory function were negatively associated with diabetes mellitus (OR, 0.978; 95% CI, 0.957–0.999; OR, 0.976; 95% CI, 0.960–0.992, respectively). Conclusion Our findings suggest that improvement in oral health, including the maintenance of masticatory function and remaining teeth, may contribute to the prevention of sarcopenia and diabetes mellitus in older adults.

Radiographic bone loss in a Scottish non-smoking type 1 diabetes mellitus population: A bitewing radiographic study. J Periodontol 2018; 89:1043-1051. [PMID: 29766516 DOI: 10.1002/jper.16-0788] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2016] [Revised: 01/31/2018] [Accepted: 02/06/2018] [Indexed: 11/08/2022]
Abstract
BACKGROUND The dental complications of uncontrolled diabetes include reduced salivary flow rate, candidiasis and periodontal manifestations. A recent meta-analysis concluded that diabetes patients have a significantly higher severity, but not extent, of destructive periodontal disease than non-diabetics. The authors reported that most type-1 diabetes studies using dental radiographic data have not controlled for confounding factors such as smoking. The aim of this cross-sectional study was to compare radiographic alveolar bone loss between type 1 diabetes (T1DM) and non-diabetes (NDM) participants in a Scottish non-smoking population. METHODS Digital bitewing radiographs for 174 Scottish adults never or ex-smoker (>5 years) participants (108 T1DM, 66 NDS), recruited from outpatient clinics throughout Greater Glasgow and Clyde, were included in the analysis. A single blinded, trained, and calibrated examiner recorded the radiographic bone loss seen on bitewing radiographs using the digital screen caliper (Screen Calliper ICONICO version 4.0 (Copyright (C) 2001-6 Iconico), New York). The bone loss was measured as the distance between the cemento-enamel junction (CEJ) and the deepest radiographic alveolar bone margin interproximally of each tooth. RESULTS T1DM participants had more radiographic alveolar bone loss throughout the all teeth measured (median:1.27 mm versus 1.06 mm, P < 0.001) and more than a two-fold increase in the risk of having sites with ≥2 mm periodontal destruction (OR = 2.297, 95%CI 1.058 to 4.986, P = 0.036) compared with non-diabetes subjects. CONCLUSIONS Patients suffering from type 1 diabetes are at higher risk of periodontitis even when controlling for multiple possible confounding factors and this difference can be detected on routine dental radiographs at an early stage. These data confirm radiographically the previously reported association between T1DM and periodontal bone loss.

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
INTRODUCTION This pilot study investigated the efficacy of dental clinics as potent sources for screening diabetes and prediabetes in undiagnosed individuals. METHODS Data were randomly collected from 385 patients (aged 40 years and older) visiting dental clinics. Patients already having a diagnosis of diabetes and/or prediabetes were excluded. Demographic data, body mass index and family and dental histories were recorded. Signs and symptoms of diabetes were investigated. Random blood glucose levels (RBGLs) were recorded. Individuals with RBGL ≥110 mg/dL underwent the oral glucose tolerance test and the glycosylated hemoglobin test (HbA1c). RESULTS Of the 385 patients, 60% (232) had RBGL <110 mg/dL, whereas 40% (153) had RBGL ≥110 mg/dL. Prevalence of confirmed diabetes and prediabetes among the study participants was 16.4% and 15.8%, respectively. Body mass index was significantly higher among patients with diabetes and prediabetes as compared with healthy controls. HbA1c level was statistically significantly higher among patients with diabetes than among patients with prediabetes. Symptoms of polyuria and polydipsia were significantly higher among patients with diabetes than in those without diabetes. CONCLUSIONS A high percentage of undiagnosed type 2 diabetes and prediabetes among patients visiting dental clinics was found compared with that reported in the medical literature. Further studies with a lager sample size are needed to confirm these results.

Abstract
OBJECTIVES A thorough and exhaustive analysis of the available studies concerning placement of endosseous dental implants in diabetic subjects has not been previously published. The aim of the present study was to perform a comprehensive and critical review of experimental and clinical studies published in the international peer-reviewed literature in the English language regarding endosseous implant installation in diabetic subjects and to draw evidence-based conclusions on the effectiveness and predictability of dental implant therapy in diabetic patients. MATERIAL AND METHODS Literature search for articles published up to and including March 2005 in the English language was performed with a personal computer (PC) using The National Library Of Medicine (http://www.ncbi.nlm.nih.gov/PubMed) and Cochrane Oral Health Group databases. Search strategy included a specific series of terms and key words. The reference lists of identified publications, relevant texts and previous workshops were also scanned. Data sources also included several hand-searched journals and contact with experts, when it was considered appropriate. Search was conducted independently by the three reviewers (S. K., I. K. K., I. F.). At the first phase of selection the titles and abstracts and at the second phase full papers were screened independently by the three reviewers. Disagreement regarding inclusion of full papers was resolved by discussion among the reviewers. RESULTS The search provided 227 potentially relevant titles and abstracts. At the first phase of evaluation, 199 publications were rejected based on title and abstract. At the second phase, the full text of the remaining 28 publications was retrieved for more detailed evaluation. These publications included 11 experimental studies and 16 clinical studies (one clinical study corresponded to two publications). Finally, 11 experimental and eight clinical studies were accepted. Clinical studies included four prospective and four retrospective studies. Because of the limited number of available studies and their heterogeneity, focusing on a specific predefined question to be answered by a systematic review was not feasible and therefore no meta-analysis was planned. CONCLUSION Within the limits of the existing investigations, experimental studies seem to reveal an impaired bone healing response to implant placement in diabetic animals compared with non-diabetic controls, both quantitatively and qualitatively. The majority of clinical studies tend to indicate that diabetes is no contraindication for implant placement, on condition that it remains under metabolic control. However, definitive guidelines with objective criteria, such as type and duration of diabetes and glucosylated hemoglobin levels, need to be established in the future.

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
BACKGROUND The potential of calcium channel blockers (CCBs) to induce gingival enlargement (GE) as well as the influence of diabetes mellitus on periodontal tissues has been well documented. This case report documents a conservative clinical approach to the management of felodipine-influenced gingival enlargement and displays a clinical and histologic case of felodipine-influenced GE in an undiagnosed type 2 diabetic patient. METHODS At the initial examination, a medical consultation was requested and two incisional biopsies were taken for pathological evaluation. The patient was diagnosed with uncontrolled type 2 diabetes. Felodipine was withdrawn and the diabetes was controlled before dental treatment was initiated. The patient then underwent selective extractions and full-mouth scaling and root planing as well as oral hygiene instructions. No surgical therapy was indicated. RESULTS The histological results demonstrated the presence of elongated rete pegs; fibrous hyperplasia; a low-grade chronic inflammatory infiltrate, predominantly consisting of lymphocytes; and collagen bundle groups randomly distributed. These features were similar to those present in other drug-influenced GE. Clinical results have demonstrated almost complete resolution of GE after the withdrawal of felodipine and the control of diabetes. Further improvements were seen after scaling and root planing and oral hygiene instructions. No recurrences were noted 12 months after initial therapy. CONCLUSIONS This report demonstrated that the control of systemic factors seemed to have the most influence on success for this particular case. Since the control of diabetes was managed at the same time as the felodipine withdrawal, it remains difficult to speculate how these two factors impacted both the severity of the GE and the therapeutic results. More importantly, the conservative treatment rendered demonstrated the stability of periodontal status during maintenance phase and the avoidance of surgical interventions.

Abstract
An association between periodontal infection and CVD has been revealed in some epidemiologic studies, whereas other studies were unable to demonstrate such an association. A link between the two diseases may be explained by shared established or nonestablished risk factors. Future studies with extended control of confounding factors and intervention studies may add to the understanding of a possible relationship between the diseases. In some cases, IE is caused by dental plaque bacteria. Several studies are suggestive of oral bacteria causing respiratory infection. The pathogenesis and course of a number of other diseases including DM and rheumatoid arthritis have been associated wish periodontitis, but more research is necessary to elucidate possible pathogenic interactions.

Abstract
AIM The purpose of this study was to assess the response of diabetics to scaling and root planing treatment and subgingival oral irrigation as adjunctive therapy. METHOD A total of 52 type 1 and 2 diabetics (mean age 51.3+/-14) with adult periodontitis were randomized to two groups. Treatment included ultrasonic scaling and scaling and root planing in both groups (control and test) plus subgingival water irrigation 2x daily for the test group. Assessments were made prior to and at 6 and 12 weeks after treatment. Parameters measured were modified gingival index (MGI), probing pocket depth (PPD), plaque index (PI), clinical attachment level (CAL), and bleeding on probing (BOP). Systemic measurement of Reactive Oxygen Species (ROS) generation, cytokines (TNF-alpha, IL-1beta, IL-10, and PGE2), and glycated hemoglobin (HbA1C). RESULTS After treatment, analysis of data showed that both groups had clinical and systemic improvement. The test group had a statistically significant reduction for MGI, PI, and BOP compared to controls (p<0.03) at 12 weeks and for ROS generation at 12 weeks (p<0.012). Unlike controls, systemic analysis of cytokines showed a statistically significant reduction from baseline for IL-1beta at 6 weeks and PGE2 at 6 and 12 weeks (p<0.05) within test group. CONCLUSION These results suggest that scaling and root planing and adjunctive therapy may be of value in establishing a healthy periodontium in diabetics.

Abstract
The periodontal health of smokers and non-smokers with non-insulin-dependent diabetes mellitus (NIDDM) and non-smokers with periodontitis who were not suffering from a systemic disease was assessed. The investigation was carried out on 60 adult subjects. Levels of blood glucose, glycosylated haemoglobin and immunoglobulins G, A and M were determined, together with the plaque index, gingival index, probing pocket depths and clinical attachment level. Periodontitis was more severe in smokers and non-smokers with NIDDM than non-smokers without NIDDM, and the periodontal condition (clinical attachment level, probing pocket depth and gingival bleeding) was better in non-smokers with NIDDM than smokers with NIDDM. The results suggest that diabetes and smoking are high-risk factors for periodontal disease.

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
Evidence points to an increased cytokine response in type 2 diabetes, especially the proinflammatory cytokines interleukin (IL)-1 beta, IL-6, and tumor necrosis factor (TNF)-alpha. Genetics, age, and, nutrition are important signals for this increased response and as reported more recently, infections and inflammation. Persistent elevation of IL-1 beta, IL-6, and TNF-alpha in the diabetic state have an effect on the liver, stimulate the release of acute-phase proteins, produce the characteristic dysregulation of lipid metabolism associated with type 2 diabetes, and have effects on pancreatic beta cells as well. In addition, TNF-alpha, a potent inhibitor of the tyrosine kinase activity of the insulin receptor, has been implicated as an etiologic factor for insulin resistance. Collectively, the evidence supports a role for cytokine elevation in the pathophysiology and metabolic abnormalities associated with diabetes. Periodontitis is an infection that is twice as prevalent in diabetic individuals compared to non-diabetics. Porphyromonas gingivalis, one of the microorganisms responsible for this infection, is able to invade endothelial cells and is a potent signal for monocyte and macrophage activation. Thus, once established in the diabetic host, this chronic infection complicates diabetes control and increases the occurrence and severity of microvascular and macrovascular complications. Unlike treatment of acute infections, modalities of treatment for chronic infections are a matter of debate. Evidence indicates that mechanical removal of subgingival infection does not result in complete elimination of periodontal infection and consequently there is no effect on diabetes control measured as reduction in glycated hemoglobin. On the other hand, studies incorporating systemic antibiotics as adjuncts to mechanical debridement result in a reduction of P. gingivalis to nondetectable levels and a concomitant reduction in glycated hemoglobin, independent of the hypoglycemic effects of diabetes drugs or insulin. The evidence supports the notion that treatment of chronic periodontal infection is essential in the diabetic patient. Assessment of infection status in diabetic patients is fundamental for appropriate treatment decisions.

Abstract
BACKGROUND Few investigations have reported on risk factors for periodontal attachment loss over time in subjects with no home or professional dental care. The purpose of this report was to identify potential risk factors for progression of periodontal attachment loss among male Sri Lankan tea laborers who participated in a 20-year investigation of the natural history of periodontal disease. METHODS Data for this report were obtained from the 154 subjects who participated in the 1970 baseline and the final 1990 examinations and included data from their interim examinations performed in 1971, 1973, 1977, 1982, and 1985. Oral health assessments included: 1) attachment levels in millimeters on mesial and mesio-buccal surfaces of all but third molar teeth; 2) plaque index (PI); 3) gingival index (GI); 4) calculus index (CI); 5) caries index (DMFS); and 6) presence or absence of teeth. Other variables included age, history of smoking, and/or use of betel nut. Statistical analyses used multivariate repeated measures analysis of variance (ANOVA). RESULTS The final adjusted model indicated that attachment loss increased significantly with age (X2 = 74.0; df = 1), GI (X2 = 45.5; df = 1), CI (X2 = 52.7; df = 1) and follow-up time (X2 = 219.8; df = 6, P<0.0001 for all variables). CONCLUSIONS Age, GI, CI, and time were significantly associated with mean attachment loss over 20 years. Neither PI, history of smoking, or history of betel nut use were significantly associated with attachment loss over time.

Abstract
BACKGROUND The periodontal disease status of 320 dentate adults, diagnosed 23.7 years previously with Type 1 insulin dependent diabetes mellitus, was evaluated. These patients had been monitored at 2-year intervals as part of a large University of Pittsburgh longitudinal study assessing the medical complications associated with insulin dependent diabetes. METHODS During one of their regularly scheduled medical examinations, a group of 320 adult dentate subjects (mean age of 32.1 years) received a periodontal examination as part of a comprehensive oral health assessment. The oral health assessment collected data regarding demographics, oral health behaviors, tooth loss, coronal and root caries, salivary functions, and soft tissue pathologies. For the periodontal assessments, 3 facial sites (mesial, midcervical, distal) of the teeth in the right maxillary/left mandibular or left maxillary/right mandibular quadrants were evaluated for calculus, bleeding on probing (BOP) and loss of gingival attachment (LOA). RESULTS Attachment loss was significantly greater for older patients whereas BOP and calculus levels were relatively constant across age categories. Univariate analyses of factors possibly related to extensive periodontal disease (LOA > or =4 mm for at least 10% of sites examined) indicated an association with older age; lower income and education; past and current cigarette smoking; infrequent visits to the dentist; tooth brushing less than once per day; older age of onset; longer duration of diabetes; and the diabetic complication of neuropathy. A multivariate regression model of all possibly significant factors found current cigarette use (odds ratio [OR] = 9.73), insulin dependent diabetes onset after 8.4 years of age (OR = 3.36), and age greater than 32 years (OR = 3.00) explained the majority of the extensive periodontal disease in this group of diabetic patients. CONCLUSIONS Management and prevention of extensive periodontal disease for Type 1 diabetic patients should include strong recommendations to discontinue cigarette smoking.

Abstract
The periodontal status of 25 patients with non-insulin dependent diabetes mellitus (NIDDM) (age range 58 to 76) was investigated and compared with 40 non-diabetic control subjects (age range 59 to 77). Surfaces with visible plaque and bleeding after probing, calculus, recessions, and pathological pockets were examined. The total attachment loss was calculated as a sum of recessions and pockets in millimeters. Mesial and distal bone loss was measured from panoramic radiographs and mean alveolar bone loss was calculated. Periodontal disease was considered advanced when mean alveolar bone loss was over 50%, or 2 or more teeth had pockets > or = 6 mm. Microbiological analysis comprised the detection of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, and Bacteroides forsythus by a polymerase chain reaction (PCR) method. Patients with NIDDM had significantly more often advanced periodontitis than control subjects, 40.0% and 12.5%, respectively. Diabetic patients did not harbor more pathogens than the control subjects. The HbA1C level deteriorated in patients with advanced periodontitis, but not in other patients with NIDDM, when compared to the situation 2 to 3 years earlier. Advanced periodontitis seems to be associated with the impairment of the metabolic control in patients with NIDDM, and a regular periodontal surveillance is therefore necessary.

Abstract
The prevalence and severity of periodontal disease is increased in patients with both insulin-deficient and insulin-resistant forms of diabetes. While a number of underlying factors likely contribute to enhanced periodontal inflammation and alveolar bone loss in diabetes, a common characteristic of these disorders, regardless of etiology, is the presence of hyperglycemia. A critical consequence of hyperglycemia is non-enzymatic glycation and oxidation of proteins and lipids. After a series of reversible reactions which lead to the generation of Schiff bases/Amadori products, a further series of complex molecular rearrangements ensues which results in the formation of the irreversible advanced glycation end products, or AGEs. AGEs accumulate during the process of normal aging in the plasma and tissues, but to an accelerated degree in patients with diabetes. A central means by which AGEs are believed to impart their pathogenic effects is via interaction with specific cellular receptors; the best-characterized of these is receptor for AGE, or RAGE. RAGE, a member of the immunoglobulin superfamily of cell surface molecules, is present in increased levels on target cells in diabetes, such as endothelial cells and monocytes. One consequence of AGE-RAGE interaction is the generation of enhanced cellular oxidant stress, a means by which cell signaling pathways may be activated, thereby resulting in altered cellular phenotype and cellular dysfunction. In this report, we will review our studies to date on AGEs and RAGE and consider the implications of their enhanced interaction in the pathogenesis of accelerated periodontal disease in diabetes.

Periodontal status and subgingival microbiota of insulin-dependent juvenile diabetics: a 3-year longitudinal study. J Periodontol 1998; 69:120-8.

Abstract
This study examined for 3 years the changes in periodontal status and the possible correlations with selected subgingival microbiota and diabetic conditions in a group of 16 insulin-dependent diabetes mellitus (IDDM, JD) patients as compared with their 16 healthy cohabiting siblings (HS). JD patients were monitored every 3 months for levels of glycosylated hemoglobin (HbA1C). Clinical and microbiological parameters were measured 6 weeks before drawing blood to determine levels of HbA1C. Periodontal parameters were measured at baseline (TO), year 2 (T2), year 3 (T3) and included: probing depth (PD), attachment level (AL), sulcus bleeding index (SBI), and plaque index (PI). Two sites in each patient were selected for microbial samples: a mesio-facial aspect of the maxillary right first molar (defined as constant site, CS) and a site with the greatest probing depth (defined as deepest site, DS). Microbial samples were analyzed by culture techniques. No significant differences in clinical parameters were found between diabetics and healthy siblings at any examination. The SBI in the non-diabetic group at T2 and at T3 was significantly lower than at baseline. PD and AL of constant sites in the diabetic group at T3 were significantly higher than baseline. There was a significant increase in Prevotella intermedia at T3 as compared with baseline for deepest sites in the diabetic group. Cluster analysis revealed, in a former study, two clusters (IV and V) at baseline which were significantly different from the overall mean regarding composition of Porphyromonas gingivalis and Capnocytophaga spp. They were not significantly different for periodontal parameters from TO to T3. These data would suggest no significant differences in clinical parameters between the diabetics and non-diabetic siblings throughout this 3-year longitudinal study.

Abstract
Recent epidemiologic surveys and studies have provided important information on the prevalence, extent, and severity of periodontal diseases in the United States. Over 50% of adults had gingivitis on an average of 3 to 4 teeth. Subgingival calculus was present in 67% of the population. Adult periodontitis, measured by the presence of periodontal pockets > or = 4 mm, was found in about 30% of the population on an average of 3 to 4 teeth. Severe pockets > or = 6 mm were found in less than 5% of the population. Attachment loss > or = 3 mm was found in 40% of the population. Gingival recession accounted for a significant amount of attachment loss. The prevalence of early-onset periodontitis ranged from less than 1% in 14- to 17-year-olds to 3.6% in young adults aged 18 to 34. Extensive and severe periodontitis was much more prevalent in minorities, people with less than a high school education, and those who had seen a dentist infrequently and had subgingival calculus. Smoking and diabetes have been identified as risk factors, especially diabetics with poor metabolic control, a long duration of the disease, and extensive subgingival calculus. Under managed care, there has been an expansion of soft tissue management programs in the offices of general dentists and referral guidelines which limit referral of patients with moderate periodontitis. Quality-assurance mechanisms will be essential for the diagnosis and treatment of persons with periodontitis.

Abstract
Serum IgG responses to the cell envelope proteins (CEPs) from Capnocytophaga sputigena, Capnocytophaga ochracea, and Capnocytophaga gingivalis were examined in periodontally healthy and periodontitis subjects, both with and without type 1 diabetes (n = 60). Serum IgG responses to CEPs were determined by immunoblotting with biotin-goat anti-human IgG and an alkaline phosphatase-streptavidin system. Reactivity was analyzed by transmission densitometry, digitization, and computer manipulation. The patients with diabetes showed significantly (p < 0.01) fewer responses to 14 CEPs (from 81 to 10 kDa) from C. sputigena, 5 CEPs (from 90 to 17 kDa) from C. gingivalis, and the 27-kDa CEP from C. ochracea than in the non-diabetic group. The periodontitis patients showed significantly (p < 0.01) fewer responses to the 25- and 11-kDa CEPs from C. sputigena, the 125- and 17-kDa CEPs from C. gingivalis, and the 42-kDa CEP from C. ochracea than in the periodontally healthy group. HLA-DR4, HLA-DR53, and HLA-DQw3 were associated with periodontitis, while only HLA-DR4 was associated with diabetes (p < 0.02). Significant (p < 0.01) correlations were found between HLA-DR2 and IgG reactivity patterns associated with non-diabetics, and between HLA-DR4 and IgG reactivity patterns associated with diabetic and periodontitis subjects. These results indicate that both type 1 diabetics and periodontitis subjects have a depressed IgG antibody profile to Capnocytophaga, which may account for an increased susceptibility to periodontitis infection. Periodontitis in type 1 diabetes may be related more to the HLA-D type and altered immune function than to the diabetes itself.

Abstract
Heart transplant patients take several medications that could affect their periodontal health. Gingival overgrowth associated with cyclosporin (immunosuppressant agent) and nifedipine (calcium channel blocker) is well documented. Candidal infections often develop because of immune suppression. This report describes the clinical and histopathological changes in the gingival tissues of a heart transplant patient and their management. The gingival tissues exhibited pronounced enlargement. The gingivae were lobulated, and the surface of the lobulations was pebbly and granular. Biopsies showed lobules of fibrous connective tissue covered by stratified squamous epithelium. The outer surfaces were dotted with numerous smaller papillations. Candidal hyphae were present in the superficial layers of the epithelium. The extensive papillary lesions appear to be related to candidiasis and constitute a condition which is best designated as papillary stomatitis. Hyperplastic gingival tissues were excised, and the patient was placed on periodic maintenance. One-year postoperative follow-up showed minor gingival growth.

Abstract
Variation in the periodontal health status and the response to oral hygiene education, scaling and root planing were studied in 36 subjects with type-1 diabetes mellitus (DM) and in 10 non-diabetic control subjects. The age range of the subjects was 24-36 years. The diabetic group was divided into 3 subgroups based on the levels of glycosylated hemoglobin (HbAlc) over a 3 year period and the presence of diabetic complications as follows: (D1) subjects with good metabolic control and no complications (n=13), (D2) subjects with varying metabolic control with/without retinopathy (n=15) and (D3) subjects with severe diabetes, i.e., with poor long-term control and/or multiple complications (n= 8). Clinical measurements (plaque, subgingival calculus, probing pocket depth, bleeding after probing and clinical attachment level) were performed at the baseline and 4 weeks and 6 and 12 months after periodontal therapy. The between-group comparisons were made using the Student t-test and ANOVA. Based on the plaque scores, the oral hygiene status was similar in all groups during the whole study. No statistically-significant differences in the periodontal health status could be found between the diabetic group as a whole and the non-diabetic controls at any examination. The level of periodontal health of the diabetics with good control and no complications (D1) and those with moderate control with/without retinopathy (D2) was on the same level with that seen in the non-diabetic controls. Our findings of the significantly higher extent of al > or =2 mm at the baseline and the fast recurrence of pd > or =4 mm during the longitudinal study in diabetic subjects with poor metabolic control and/or multiple complications (D3) indicate increased periodontal breakdown as a complication of DM in these subjects. To be able to assess the periodontal prognosis and the need for periodontal therapy on an individual basis,the clinical practitioner should be well aware of the diabetic status of his/her patients.

Abstract
Eight female and 3 male patients from a group of 30 patients studied 10 years earlier and who had received no periodontal treatment during this period, in order to evaluate the progression of untreated periodontal disease in patients with insulin-dependent diabetes mellitus, were evaluated in terms of plaque accumulation, gingival inflammation, probing depth, and alveolar bone loss. The total number of dental surfaces that presented clinically detectable plaque deposits increased significantly (29% to 43%; P < 0.01; chi 2 = 46.36). Site-specific comparisons for plaque index between studies showed a significant variation (P < 0.01) in the upper arch only for palatal surfaces and in the lower arch for the buccal and lingual surfaces. The total dental surfaces with inflamed surrounding gingiva increased from 11% to 33% in this study (P < 0.01; chi 2 = 175.78). Site-specific comparison for gingival index showed a significant variation for all upper surfaces, while such difference for the lower arch was significant only for the buccal and lingual surfaces. The arithmetic means for the probing depth for the upper buccal, upper palatal, lower buccal, and lower lingual surfaces increased significantly (P < 0.01). The arithmetic means of alveolar bone loss also increased significantly for the upper posterior and lower regions (P < 0.01) and for the upper anterior and lower anterior regions (P < 0.05). The correlation between age and probing depth was significant only for the upper palatal region (P < 0.01). The correlation between age and bone loss was significant only for the upper posterior region (P < 0.05). The results of this follow-up study suggest that despite little variation in plaque accumulation, gingival inflammation, probing depth, and bone loss increased after a 10-year interval in patients who had received no periodontal treatment during this period.

Abstract
Diabetes mellitus is a systemic disease with profound effects on oral health and periodontal wound healing. Uncontrolled diabetes adversely affects surgical wound healing and is often associated with abnormal proliferation of fibroblasts, excessive angiogenesis and poor bone regeneration. Human gingival fibroblasts and periodontal ligament cells from both diabetics and non-diabetics were evaluated for growth responses following culture in 20 mM glucose, a concentration compatible with blood glucose levels in uncontrolled diabetics. Gingival fibroblasts derived from 9 non-diabetic patients and 3 insulin-dependent diabetics either proliferated or showed little change of growth in elevated glucose. Enhanced proliferation was observed following 1 wk of culture in glucose. Growth of periodontal ligament cells from 5 non-diabetic patients was inhibited by 20 mM glucose. Fibroblasts that were markedly growth stimulated were probed for expression of basic fibroblast growth factor (bFGF) using a reverse-transcribed polymerase chain reaction (RT-PCR). Results indicate that fibroblasts exhibiting the greatest increase in growth in response to high glucose also exhibited increased expression of bFGF. No changes were observed in mRNA expression for platelet-derived growth factor-AA, platelet-derived growth factor-BB, insulin-like growth factor and transforming growth factor-beta 1. Mitogenic effects induced by the cytosol of fibroblasts exhibiting increases of growth in 20 mM glucose were abrogated by neutralizing antibodies to bFGF. In addition, some periodontal ligament cells that were growth inhibited by high glucose had reduced expression of bFGF. These data suggest that bFGF may play a role in the abnormal wound healing associated with periodontal surgery of uncontrolled diabetics.

Abstract
The periodontal status of 77 diabetic children and adolescents, and 77 paired, systemically-healthy, sex- and age-matched control subjects, was clinical examined. Fasting blood glucose, fructosamine and glycosylated haemoglobin (HbA1) values were determined. The mean periodontal pocket depths, clinical attachment levels and the parameters to assess diabetes mellitus from the diabetic group were significantly higher than those of the controls. We found a positive correlation between the duration of diabetes and clinical attachment loss, but not with periodontal probing depth, plaque index and gingival index in the diabetic group. A positive correlation was also assessed between the present serum fructosamine and gingival index in the diabetic group, but not in controls.

Abstract
The aim of this study was to define a population of diabetics exhibiting an increased risk of developing severe periodontitis by comparing the medical status of 2 groups of diabetics, 1 with no/minor periodontal disease and 1 with severe periodontal disease. The case-control study consisted of 2 parts, a baseline study and a follow-up study. 39 case-control pairs were selected. They were adult, long-duration, insulin-dependent diabetics matched according to sex, age and diabetes duration. One individual in each pair (the CASE) exhibited severe periodontal disease while the other (the CONTROL) exhibited gingivitis or only minor alveolar bone loss. The median age of the cases was 58 years (range 36 to 70 years) and of the controls 59 years (range 37 to 69 years). The median disease duration in cases and controls was 24 years and 25 years, respectively. The median follow-up time was 6 years. The medical variables analysed were weight, insulin dose, systolic and diastolic blood pressure, vibratory threshold, triglycerides, total-cholesterol, HDL-cholesterol, creatinine, HbA1, proteinuria, ECG, retinopathy, stroke, transient ischemic attacks (TIA), angina, myocardial infarct, heart failure, hypertension, intermittent claudication, foot ulcer, death, cause of death, and smoking habit. Biochemical analyses and clinical variables used as a routine in the monitoring of diabetics failed to differentiate between diabetics with severe and minor periodontal disease. In the follow-up study, significantly higher prevalences of proteinuria and cardiovascular complications such as stroke, TIA, angina, myocardial infarct and intermittent claudication were found in the case group. An association between renal disease, cardiovascular complications and severe periodontitis seems to exist. This indicates that a closer cooperation between the diabetologist and the dentist is necessary in monitoring the diabetic patient.

Abstract
The subgingival microflora was assessed by means of dark field microscopy in 106 pockets of 47 subjects with long-term insulin-dependent diabetes mellitus (IDD). The microbiota of 55 healthy sulci (probing depth < 4 mm) and 51 periodontally diseased (probing depth > or = 4 and 6 mm) pockets were analyzed. The mean duration of the IDD of the diabetic subjects was 23.7 years (range from 10 to 41 years). The diabetic patients, aged 30-65 years, were under medical treatment at the III Department of Medicine, University of Helsinki Central Hospital, and at 2 clinics of the Helsinki Health Centre. Based upon their long-term medical records, 26 subjects were assessed to have poorly controlled insulin-dependent diabetes mellitus (PIDD) and 21 had controlled insulin-dependent diabetes (CIDD). The PIDD subjects exhibited higher mean blood glucose levels (12.9 +/- 4.6 mmol/l, mean +/- S.D.) than the CIDD subjects (7.9 +/- 3.6 mmol/l) (p < 0.001, t-test). The mean glycosylated hemoglobin HBA1 (HBA1c) levels were 11.2 +/- 4.6% (10.3 +/- 1.2%) and 8.8 +/- 1.8% (7.7 +/- 1.4%) for PIDD and CIDD subjects, respectively. These differences were statistically significant (p < 0.01 and p < 0.001, t-test). For each individual, site-specific recordings were made for plaque index and bleeding index scores, probing depth, loss of attachment and radiographic loss of alveolar bone. Dark field microscopy analysis of the presence of spirochetes, motile rods, cocci, non-motile rods, filaments and fusiforms was performed in the total of 106 pockets. According to the results of the dark field microscopy, the % of spirochetes and motile rods in the periodontally diseased pockets was significantly higher in the PIDD than in the CIDD subjects (9.2 +/- 13.4% and 10.8 +/- 14.3% versus 4.0 +/- 5.2% and 3.1 +/- 3.2%, p < 0.01 and p < 0.001, chi 2-test, respectively). Moreover, the PIDD subjects had lower mean %s of coccoid cells in periodontally diseased sites than the CIDD subjects (52.1 +/- 20.8% versus 60.7 +/- 9.0%, p < 0.001, chi 2-test).

Abstract
The present investigation was performed to study the frequency of recurrence of periodontitis in diabetic subjects, who, prior to the initiation of a 5-year period of monitoring, were treated for moderate to advanced periodontal disease. 20 patients with diabetes, type 1 (IDDM) or type 2 (NIDDM) and 20, sex and age matched, controls with similar amounts of periodontal tissue destruction, were selected for the study. Following a screening examination, all patients were subjected to non-surgical periodontal therapy (oral hygiene instruction, supra- and subgingival scaling). 3 months later, the baseline examination for the study was performed. This included assessments of several parameters such as: number of teeth, plaque, gingivitis, probing pocket depth and probing attachment level. 6 months after the baseline examination, all 40 subjects were recalled for a 2nd examination. Sites which at this 6-month examination exhibited bleeding on probing, and had probing depth > 5 mm, were scheduled for additional surgical therapy (modified Widman flap). Following this selective additional therapy, the main period of monitoring was initiated. During this period, a plaque control program was repeated every 3 months. Re-examinations regarding plaque, gingivitis, probing depth and probing attachment level were performed 12, 24 and 60 months after the baseline examination. The findings from the examinations disclosed that diabetics and non-diabetics alike, treated for moderately to advanced forms of adult periodontitis, during a subsequent 5-year period, were able to maintain healthy periodontal conditions. Thus, the frequency of sites which exhibited signs of recurrent disease was similar in the 2 study groups.

Abstract
Deciphering the relative roles of heredity and environmental factors ("nature vs. nurture") in the pathogenesis of dental caries and diseases of the periodontium has occupied clinical and basic researchers for decades. Success in the endeavor has come more easily in the case of caries; the complex interactions that occur between host-response mechanisms and putative microbiologic pathogens in periodontal disease have made elucidation of genetic factors in disease susceptibility more difficult. In addition, during the 30-year period between 1958 and 1987, only meager resources were targeted toward the "nature" side of the nature/nurture dipole in periodontology. In this article, we present a brief history of the development of genetic epistemology, then describe the three main research mechanisms by which questions about the hereditary component of diseases in humans can be addressed. A critical discussion of the evidence for a hereditary component in caries susceptibility is next presented, also from a historical perspective. The evolution of knowledge concerning possible genetic ("endogenous", "idiotypic") factors in the pathogenesis of inflammatory periodontal disease is initiated with an analysis of some foreign-language (primarily German) literature that is likely to be unfamiliar to the reader. We identify a turning point at about 1960, when the periodontal research community turned away from genetics in favor of microbiology research. During the past five years, investigators have re-initiated the search for the hereditary component in susceptibility to common adult periodontal disease; this small but growing body of literature is reviewed. Recent applications of in vitro methods for genetic analyses in periodontal research are presented, with an eye toward a future in which persons who are at risk--genetically predisposed--to periodontal disease may be identified and targeted for interventive strategies. Critical is the realization that genes and environment do not act independently of each other; the appearance or magnitude of heritability may differ with various environments.

Abstract
The subgingival microflora and serum antibody response were examined in long-duration insulin-dependent diabetics and age- and sex-matched non-diabetics. The material consisted of 9 diabetics aged 40-49 years and 19 aged 50-59 years, 13 non-diabetics aged 40-49 years and 21 aged 50-59 years. The bacterial species studied (Actinobacillus actinomycetemcomitans, Campylobacter rectus, Capnocytophaga spp, Eikenella corrodens, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia) were recovered in diabetics as well as in non-diabetics. Significantly more diabetics in both age groups harboured P. gingivalis compared to non-diabetics. Prevalence of P. gingivalis was associated with deepened periodontal pockets among non-diabetics but not among diabetics. In diabetics and non-diabetics, the serum antibody titres for most antigens were similar.

Abstract
This study compared the periodontal status of a juvenile diabetic study group with that of a non-diabetic control group similar in age and sex. The study group consisted of 26 type I diabetic patients with an average age of 13.42 years and 24 control subjects of similar age. The diabetic subjects were evaluated with glycosylated hemoglobin (GHb) to obtain a measure of diabetic control. Clinical periodontal evaluations were performed for all teeth in each subject, and consisted of the plaque index, gingival fluid flow, gingival index, probing depths, clinical attachment levels, recession, and bleeding on probing. Analysis of the data demonstrated no statistically significant differences in the overall means for the 2 groups for average attachment loss, probing depths, recession, gingival index, plaque index, gingival fluid flow, or bleeding on probing. There was no significant association between the level of control of diabetes (GHb) and clinical variables. However, comparisons based on site-specific measurements showed the gingival index to be somewhat higher among the diabetics (p = 0.0002), and examination of interaction effect plots showed the diabetic group to have higher average gingival index for most teeth and higher or the same plaque index levels on all teeth relative to controls. Thus, a young study population with type I diabetes mellitus was found to have significantly increased severity of inflammatory gingival disease compared to controls of similar age.

Abstract
This study examined the relationship between the severity of periodontal disease and organ complications in long-term Type 1 or insulin-dependent diabetes mellitus patients, taking account of the severity and concomitant existence of these complications. The population studied consisted of 26 Type 1 diabetics 26 to 34 years old, who had had diabetes for at least 10 years. Severity of periodontal disease was shown to increase with severity of organ complications. Patients with advanced complications had significantly more bleeding on probing, pockets > or = 4 mm deep, and more attachment loss than patients with incipient complications or no complications. Stepwise multiple regression analysis showed that the existence of advanced complications was the only diabetes-related factor predicting pockets > or = 4 mm deep. Subgingival calculus, sex, and smoking were other significant variables. Retinopathy was the organ complication most suited to comparison, since it is usually the first to appear and can easily be classified from non-existent to severe. Differences in severity of periodontal disease were less obvious if metabolic balance alone was considered than between subgroups formed on the basis of the existence of advanced complications. Severity of periodontal disease and the existence of complications were more closely related to long-term glucose balance than single, most recent HbA1 values. Prevalence of pockets at sites with subgingival calculus increased with severity of complications.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The association of periodontal disease with diabetes was studied in non-insulin dependent diabetes mellitus (NIDDM) patients. In a cross-sectional design, 100 patients (46 males and 54 females) were selected in 4 groups according to age and years since diagnosis of diabetes. The groups were: group 1, > 55 years old, diabetes diagnosed > or = 5 years; group 2, < or = 55 years old, diabetes diagnosed > or = 5 years; group 3, > 55 years, diabetes diagnosed < 5 years; and group 4, < or = 55 years, diabetes diagnosed < 5 years. Buccal and lingual pockets were deeper and lingual and buccal recessions greater for groups diagnosed 5 or more years ago, (P < 0.0001). In groups diagnosed less than 5 years, higher recession indices were found for patients older than 55. The loss of buccal insertion was also greater for groups diagnosed 5 or more years ago (P < 0.0001). For groups diagnosed less than 5 years ago, the loss was greater in the group older than 55 (P = 0.01). There was a marginal difference in gingival bleeding among the 4 groups (P = 0.047). Post-hoc analysis showed differences between the 2 groups who had been diagnosed less than 5 years, with lower indices for patients < or = 55. All groups were statistically different regarding bone loss (P < 0.0001), with higher indices for the groups with older age, and for groups with 5 or more years since diagnosis. There was no difference in dental mobility among the 4 groups (P = 0.0981). It was concluded that years since diagnosis of diabetes is more significant than age for severity of periodontal disease in NIDDM.

Abstract
In the present site-by-site follow-up study, the change in amount of approximal alveolar bone was assessed after 1 year from the baseline examination in 38 and after 2 years in 22 dentate subjects all with insulin-dependent diabetes mellitus. The diabetics, aged 35 to 56 years at baseline, had a history of a mean duration of 18 years of insulin-dependent diabetes mellitus and were under medical treatment at the outpatient clinic of the III Department of Medicine, University Central Hospital of Helsinki as well as at 2 diabetic clinics of the Helsinki Health Centre. Based upon their long-term medical records, 26 subjects were after 1 year, and 16 subjects after 2 years from the baseline, identified as having poorly controlled insulin-dependent diabetes (PIDD). At the 1-year examination, 12 subjects were classified as having controlled insulin-dependent diabetes (CIDD) as compared to 6 subjects at the 2-year examination. After 1 and 2 years, from baseline, site-by-site measurements were recorded for plaque index scores, bleeding after probing, loss of attachment, and radiographic loss of alveolar bone. After 1 and 2 years from baseline, the PIDD subjects exhibited higher mean %s of sites with improved bleeding scores (P < 0.01, chi 2-test) than the CIDD subjects. At the 2-year examination, the mean % of sites with loss of approximal alveolar bone was greater in the PIDD than in the CIDD group (P < 0.05, chi 2-test). The greatest differences between PIDD and CIDD subjects were found when recordings for only canines were analyzed at the 1- and 2-year examinations (P < 0.05, chi 2-test). The results of our current 2-year longitudinal site-by-site examinations confirm earlier results that poorly controlled insulin-dependent diabetes mellitus is strongly related to the amount of alveolar bone loss.

Abstract
The purpose of this study was to evaluate the association between long-term control of diabetes mellitus (DM) and periodontitis. A total of 75 diabetics (Type I or II) aged 20-70 years with long-term records of their diabetic control were selected for the study. The following periodontal variables were recorded in a randomized half-mouth examination: plaque, calculus (+/-), probing depth (pd) and attachment loss (al). The mean of glycosylated hemoglobin measurements (HbAlc) over the past 2-5 years was used to indicate the long-term control of DM. The study participants were divided into well-, moderately- and poorly-controlled diabetics. An increase in the prevalence, severity and extent of periodontitis with poorer control of diabetes was observed. The extent of calculus also increased with poorer control. In a multiple regression analysis, calculus and long-term control of diabetes were significant variables when pd > or = 4 mm was used as the dependent variable. Age was a significant predictor for al > or = 3 mm but not for pd > or = 4 mm. Sex, duration and type of DM were not significant variables in the regression models. Less than 2% of sites with no calculus demonstrated pd > or = 4 mm. When calculus was present, the frequency of pd > or = 4 mm increased from 6% in the well-controlled diabetics to 16% in the poorly-controlled ones. We conclude that periodontitis in diabetics is associated with long-term metabolic control and presence of calculus.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The aim of this study was to analyse periodontal disease experience in 40- to 70-year-old, sex-matched insulin-dependent diabetics and non-diabetics. The study involved 83 diabetics and 99 non-diabetics. The clinical and radiographic examination comprised recordings of number of teeth, presence of plaque, gingival conditions, probing pocket depth and alveolar bone level (main variable). Diabetics aged 40 to 49 years had more periodontal pockets > or = 6 mm and more extensive alveolar bone loss than non-diabetics in the same age-group. There was also a significantly higher number of subjects belonging to classification groups with severe periodontal disease experience among diabetics in that age-group. In the age-groups 50-59 and 60-69 years, no major differences were found. The disease duration in these 3 age groups was 25.6 years, 20.5 years and 18.6 years, respectively, and the age of onset thus appears to be an important risk factor for future periodontal destruction.
