Abstract
BACKGROUND The aim of this study was to assess the prevalence, extent, and severity of clinical attachment loss (CAL) and to investigate the association of demographic, socioeconomic, and behavioral risk indicators with CAL in an untreated isolated population in Brazil. METHODS All subjects aged > or =12 years were identified by a census. Participants were submitted to a full-mouth clinical examination of six sites per tooth and were interviewed using a structured, written questionnaire. RESULTS Among the 214 subjects who were interviewed and examined clinically, CAL > or =5 mm in at least one site was observed in 8% of the 12- to 19-year-olds and in all dentate subjects > or =50 years of age; the age-dependent prevalence of CAL > or =7 mm in at least one site ranged from 5% among 12- to 19-year-olds to 83% among subjects > or =50 years old. Multivariate analysis identified plaque (odds ratio [OR] = 2.8), supragingival calculus (OR = 2.9 to 10.6), age > or =30 years (OR = 11.4), and smoking (OR = 2.4) as risk indicators for CAL > or =5 mm and smoking (OR = 8.2) as a risk indicator for CAL > or =7 mm. CONCLUSIONS CAL is highly prevalent in this isolated population. The high occurrence of CAL in young age groups and the confirmation of traditional risk indicators for CAL in this study suggest that other factors, such as host susceptibility, may be needed to explain the high levels of CAL found. Age and behavioral factors were risk indicators associated significantly with the CAL found in this population and may be useful indicators of high-risk subjects for periodontal diseases.

Abstract
AIM To determine whether peripheral blood mononuclear cells (PBMCs) from chronic periodontitis patients differ from PBMCs from matched control patients in their capacity to form osteoclast-like cells. MATERIAL AND METHODS PBMCs from 10 subjects with severe chronic periodontitis and their matched controls were cultured on plastic or on bone slices without or with macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor-kappaB ligand (RANKL). The number of tartrate-resistant acid phosphatase-positive (TRACP(+)) multinucleated cells (MNCs) and bone resorption were assessed. RESULTS TRACP(+) MNCs were formed under all culture conditions, in patient and control cultures. In periodontitis patients, the formation of TRACP(+) MNC was similar for all three culture conditions; thus supplementation of the cytokines was not needed to induce MNC formation. In control cultures, however, M-CSF or M-CSF/RANKL resulted in higher numbers compared with cultures without cytokines. Upregulations of osteoclast marker mRNA cathepsin K and carbonic anhydrase II confirmed the osteoclastic character. Bone resorption was only observed when PBMCs were cultured in the presence of M-CSF and RANKL. CONCLUSION Our data indicate that PBMCs from periodontitis patients do not need priming by M-CSF to become osteoclast-like cells, suggesting that PBMCs from periodontitis patients are present in the circulation in a different state of activity.

Abstract
AIM The aim of this secondary analysis is to explore whether the application of different definition criteria of periodontitis, used in other similar studies, has an influence on the significance of the association between periodontitis and prematurity or low birth weight. MATERIAL AND METHODS Fourteen periodontitis definitions and more than 50 periodontal disease continuous measurements, found in 23 published studies, were applied to a cohort study that included 1296 pregnant women. The associations with adverse pregnancy outcomes were analysed using logistic regression analysis. RESULTS Six of the 14 tested definitions of periodontitis resulted in statistically significant adjusted odds ratios (ORs) for some of the adverse pregnancy outcomes, while no significance was found for the other eight case definitions. Out of more than 50 periodontal continuous measurements tested, only 17 demonstrated statistically significant ORs. CONCLUSIONS Our results support the hypothesis that the significance of the association between periodontal disease and pregnancy outcomes may be determined by the periodontal disease definition or measurement used.

Abstract
BACKGROUND Besides being a risk factor for cardiovascular diseases, certain cancers and type II diabetes, obesity has been suggested to be a risk factor for periodontitis. A number of epidemiological studies have studied the association between obesity and periodontitis, but the results have been partly inconclusive. The aim of this study was to examine the association of body weight with periodontal infection. MATERIAL AND METHODS The association between body weight and periodontal infection was examined using a nationally representative Health 2000 Health Examination Survey. The study was based on a subpopulation of dentate non-diabetic subjects aged 30-49 (n=2841). Periodontal infection was measured by the number of teeth with periodontal pockets of 4 mm or deeper and 6 mm or deeper. Body weight was measured using body mass index (BMI). RESULTS We detected a weak exposure-response association of BMI with teeth with deepened periodontal pockets after controlling for smoking habits by restricting the sample to subjects who have never smoked and for other potential confounders by including them in the multivariate models. CONCLUSIONS The results showed an association between body weight and periodontal infection among the non-diabetic, non-smoking population aged 30-49. Additional research is needed to determine the nature of this association.

Abstract
BACKGROUND Smoking is recognized as the primary behavioural risk factor for periodontal attachment loss (AL), but confirmatory data from prospective cohort studies are scarce. AIM To quantify the association between cigarette smoking patterns and AL by age 32. METHODS Periodontal examinations were conducted at ages 26 and 32 in a longstanding prospective study of a birth cohort born in Dunedin (New Zealand) in 1972/1973. Longitudinal categorization of smoking exposure was undertaken using data collected at ages 15, 18, 21, 26 and 32. RESULTS Complete data were available for 810 individuals of whom 48.9% had ever smoked (31.5% were current smokers). Compared with never-smokers, long-term smokers (and other age-32 smokers) had very high odds ratios (ORs of 7.1 and 5.7, respectively) for having 1 +sites with 5 +mm AL, and were more likely to be incident cases after age 26 (ORs of 5.2 and 3.2, respectively). Two-thirds of new cases after age 26 were attributable to smoking. There were no significant differences in periodontal health between never-smokers and those who had quit smoking after age 26. CONCLUSIONS Current and long-term smoking in young adults is detrimental to periodontal health, but smoking cessation may be associated with a relatively rapid improvement in the periodontium.

Abstract
AIM The aim of this study was to determine the association between periodontitis and the incidence of preterm birth (PB), low birth weight (LBW) and preterm low birth weight (PLBW) MATERIAL AND METHODS: One thousand and ninety-six women were enrolled. Periodontal data, pregnancy outcome variables and information on other factors that may influence adverse pregnancy outcomes were collected. Data were analysed using a logistic regression model. RESULTS The incidence of PB and LBW was 6.6% and 6.0%, respectively. The incidence of PLBW was 3.3%. PB was related to mother's age, systemic diseases, onset of prenatal care, previous PBs, complications of pregnancy, type of delivery, the presence of untreated caries and the presence of periodontitis (odds ratio 1.77, 95% confidence interval: 1.08-2.88). LBW was related to mother's smoking habits, ethnicity, systemic diseases, previous LBW babies, complications of pregnancy and type of delivery. PLBW was related to mother's age, onset of prenatal care, systemic diseases, previous LBW babies, complications of pregnancy and type of delivery. CONCLUSIONS The factors involved in many cases of adverse pregnancy outcomes have still not being identified, although systemic infections may play a role. This study found a modest association between periodontitis and PB. Further research is required to establish whether periodontitis is a risk factor for PB and/or LBW.

Abstract
UNLABELLED Matrix metalloproteinase (MMP)-13 is a collagenase involved in extracellular matrix degradation either by its direct degradative effects or by processing bioactive substrates. The aim of this study was to determine the levels of MMP-13 and tissue inhibitor of metalloproteinase (TIMP)-1 in gingival crevicular fluid (GCF) and gingival biopsies obtained from active and inactive sites during chronic periodontitis progression. MATERIALS AND METHODS This was a longitudinal study in which chronic periodontitis patients with moderate to severe disease were included and followed until they developed progression determined by the tolerance method. GCF samples were obtained from periodontitis, active, inactive and healthy sites and additional gingival biopsies were taken from active and inactive sites. MMP-13 and TIMP-1 determinations were carried out by immunodot blots and immunowestern blots. RESULTS In progressive periodontitis, MMP-13 and TIMP-1 remained unchanged between active and inactive sites, but as the TIMP-1 relative levels increased together with MMP-13 elevation in inactive samples, an inverse correlation was observed in active sites. Besides, MMP-13 was undetectable in healthy controls. CONCLUSION Chronic periodontitis is characterized by increased MMP-13 expression. During disease progression, active sites tended to decrease TIMP-1 levels in association with MMP-13 elevation.

Abstract
Many definitions of periodontitis have been used in the literature for population-based studies, but there is no accepted standard. In early epidemiologic studies, the two major periodontal diseases, gingivitis and periodontitis, were combined and considered to be a continuum. National United States surveys were conducted in 1960 to 1962, 1971 to 1974, 1981, 1985 to 1986, 1988 to 1994, and 1999 to 2000. The case definitions and protocols used in the six national surveys reflect a continuing evolution and improvement over time. Generally, the clinical diagnosis of periodontitis is based on measures of probing depth (PD), clinical attachment level (CAL), the radiographic pattern and extent of alveolar bone loss, gingival inflammation measured as bleeding on probing, or a combination of these measures. Several other patient characteristics are considered, and several factors, such as age, can affect measurements of PD and CAL. Accuracy and reproducibility of measurements of PD and CAL are important because case definitions for periodontitis are based largely on either or both measurements, and relatively small changes in these values can result in large changes in disease prevalence. The classification currently accepted by the American Academy of Periodontology (AAP) was devised by the 1999 International Workshop for a Classification of Periodontal Diseases and Conditions. However, in 2003 the Centers for Disease Control and Prevention and the AAP appointed a working group to develop further standardized clinical case definitions for population-based studies of periodontitis. This classification defines severe periodontitis and moderate periodontitis in terms of PD and CAL to enhance case definitions and further demonstrates the importance of thresholds of PD and CAL and the number of affected sites when determining prevalence.

Abstract
BACKGROUND The vitamin D receptor (VDR) is involved in a variety of biological processes, such as bone metabolism and modulation of the immune response. Recent findings suggest that the pathway involving bone mineral density-mediated effects is important for the development of periodontitis, but their effects of combined VDR gene polymorphisms have not been confirmed on periodontitis. We assessed the relationship between ApaI, BsmI, and FokI VDR polymorphisms and the risk of severe chronic periodontitis among Japanese adult men. MATERIALS AND METHODS In a cross-sectional study, we examined 97 unrelated healthy Japanese men (mean age: 45.6 years, range: 22-59). A clinical examination was performed at a worksite health checkup, and information was obtained using a self-reported questionnaire. DNA was extracted from whole blood, and the VDR ApaI, BsmI, and FokI polymorphisms were genotyped using polymerase chain reaction. RESULTS F-carriers of FokI VDR polymorphisms were less likely to develop severe chronic periodontitis than non-F-carriers (p = 0.09). The ApaI and BsmI VDR polymorphisms did not show significant differences in the alleles or genotypes between the subjects with or without severe chronic periodontitis. The haplotype analysis of the three combined VDR polymorphisms revealed that the Abf homozygote had a notably higher prevalence of severe chronic periodontitis than the others, and adjustments for age, smoking status, number of teeth present, and prevalence of diabetes did not change this association (OR = 7.5; 95% CI = 1.6-34.4; p = 0.01). CONCLUSION The VDR haplotype constructed from the ApaI, BsmI, and FokI polymorphisms is related to the risk of severe chronic periodontitis in Japanese men.

Abstract
AIM To investigate the association of polymorphisms in the osteoprotegerin (OPG) and interleukin 1 (IL-1) genes with chronic periodontitis (CP). MATERIAL AND METHODS One hundred and ninety-four individuals (97 CP patients, 97 controls) were genotyped for the OPG polymorphisms Lys3Asn and Met256Val and for the IL-1 polymorphisms IL-1A (-889C/T) and IL-1B (+3953C/T). RESULTS The homozygous variants coding for Lys3 were present at a higher frequency, whereas Asn3 and Met256 were present at a lower frequency in CP patients/controls (Lys3: 31%/25%, Asn3: 23%/32% and Met256: 66%/73%). Heterozygosity for Lys3Asn was observed at a higher frequency in CP patients/controls (46%/43%). Homozygosity for the Val256 genotype was observed in two CP patients (one in controls). Met256Val heterozygosity was more prevalent in CP patients/controls (32%/20%). All differences were statistically not significant between CP patients and controls. In contrast, both IL-1 polymorphisms were statistically significant. The heterozygous variant for IL-1A was present in 32% of the CP patients and in 20% of the controls (homozygosity (patients/controls) CC: 10%/21% and TT: 55%/33%). Heterozygosity for IL-1B was observed in 37% of the CP patients versus 34% in the controls (homozygosity (patients/controls) CC: 26%/57% and TT: 37%/9%). CONCLUSION While the association between the IL-1 polymorphisms and CP was confirmed, no association between the OPG polymorphisms and CP could be found.

Abstract
OBJECTIVE The aim was to investigate whether there was an association between obesity and periodontitis in a homogeneous group of 60-70-year-old Western European men. The study also explored whether a high body mass index (BMI) in early life predicted poor periodontal status in later life. METHODOLOGY A representative sample of the male population of UK, who were enrolled in a cohort study of cardiovascular disease, was examined between 2001 and 2003. A total of 1362 men with six or more teeth completed a questionnaire, had a clinical periodontal examination and had their weight and height recorded. Multivariable analysis was carried out using logistic regression with adjustment for possible confounders. Models were constructed with low- and high- threshold periodontitis as dependent variables and with BMI as a categorical predictor variable. Low-threshold periodontitis was identified when at least two teeth had >/=6 mm loss of attachment and at least one site had a pocket of >/=5 mm. High-threshold periodontitis was identified when >/=15% of sites had >/=6 mm loss of attachment and there was deep pocketing (>/=6 mm). Modelling was repeated for other predictor variables including BMI at 21 years of age and change in weight since 21 years of age. RESULTS Two hundred and ninety-eight (21.9%) of the men studied, who had a BMI of >30 kg/m(2), were classified as obese. Obesity was associated with low-threshold periodontitis, odds ratio (OR)=1.77 (p=0.004) after adjustment for confounders. The BMI at 21 years of age did not predict periodontitis in the men investigated. Participants who had experienced a large (>30%) increase in weight during adulthood had an increased risk of poor periodontal condition; however, this was attenuated and no longer significant after adjustment for confounders. CONCLUSIONS It is concluded that obesity was associated with periodontitis in the homogeneous group of 60-70-year-old European men investigated. High BMI levels in early life did not predict periodontitis in later life in the men studied.

AIM This study aimed at evaluating the prevalence of putative periodontal pathogens (Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella nigrescens, Treponema denticola) in saliva of children with mixed dentition at two different time points, correlating these findings with a clinical parameter of gingival health. DESIGN Polymerase chain reaction (PCR) detection was used to determine the prevalence of these bacteria in saliva of 64 children in 2003 and 60 children in 2004. Gingival health was assessed by gingival index. RESULT Sixty-two (96.9%) and 50 (83.3%) children presented low gingival inflammation, whereas 2 (3.1%) and 10 (16.7%) had moderate scores in 2003 and 2004, respectively. Majority of the children (81.3% in 2003 and 73.3% in 2004) had detectable levels of at least one of the bacteria. The prevalence found was of 4.7% and 1.7% for A. actinomycetemcomitans, 6.3% and 8.3% for P. gingivalis, 23.4% and 48.3% for P. nigrescens (P < 0.05), and 71.9% and 50% for T. denticola (P < 0.05) in 2003 and 2004, respectively. No significant relationship between gingival index and presence of these bacteria and combination of different species was found. CONCLUSION A high percentage of children harboured at least one of the putative periodontal pathogens in saliva, but presented periodontally healthy conditions.

Abstract
Chronic periodontitis is an inflammatory disease that affects the supporting tissues of the teeth. It is initiated by specific bacteria within the plaque biofilm and progresses due to an abnormal inflammatory-immune response to those bacteria. Periodontitis is the major cause of tooth loss and is also significantly associated with an increased risk of stroke, type-2 diabetes and atheromatous heart disease. Oxidative stress is reported in periodontitis both locally and peripherally (serum), providing potential mechanistic links between periodontitis and systemic inflammatory diseases. It is therefore important to examine serum antioxidant concentrations in periodontal health/disease, both at an individual species and total antioxidant (TAOC) level. To determine whether serum antioxidant concentrations were associated with altered relative risk for periodontitis, we used multiple logistic regression for dual case definitions (both mild and severe disease) of periodontitis in an analysis of 11,480 NHANES III adult participants (>20 y of age). Serum concentrations of vitamin C, bilirubin, and TAOC were inversely associated with periodontitis, the association being stronger in severe disease. Vitamin C and TAOC remained protective in never-smokers. Higher serum antioxidant concentrations were associated with lower odds ratios for severe periodontitis of 0.53 (CI, 0.42,0.68) for vitamin C, 0.65 (0.49,0.93) for bilirubin, and 0.63 (0.47,0.85) for TAOC. In the subpopulation of never-smokers, the protective effect was more pronounced: 0.38 (0.26,0.63, vitamin C) and 0.55 (0.33,0.93, TAOC). Increased serum antioxidant concentrations are associated with a reduced relative risk of periodontitis even in never-smokers.

Abstract
AIM To estimate the prevalence of periodontal disease in Brazilian adults and to test its association with skin colour after controlling for socio-demographic variables. METHODS The periodontal status of 11,342 Brazilian adults was informed by a nationwide oral health survey. Socio-demographic variables included skin colour, gender, schooling, per capita income, age and geographical region. The association between periodontal disease and skin colour was tested by a logistic regression model, adjusting for covariates. Interactions between skin colour and socio-demographic variables were tested. RESULTS The prevalence of periodontal diseases was 9.0% [95% confidence interval (CI) 7.6-10.3]. Lighter-skinned black people (pardos) and dark-skinned black people (pretos) presented higher levels of periodontal disease when compared with white people [odds ratio (OR)=1.5; 95% CI 1.2; 1.8; OR=1.6; 95% CI 1.2; 2.1, respectively] even after controlling for age, gender, schooling, per capita income and geographic region. No interactions were statistically significant. CONCLUSION Skin colour was significantly associated with periodontal disease among Brazilian adults after adjustment for socio-economic and demographic covariates.

Abstract
OBJECTIVE To study whether there is an association between the frequency of functional polymorphisms in the toll-like receptor 4 (TLR4) and cluster differentiation 14 (CD14) genes and periodontitis. METHODOLOGY Genotyping for the TLR4 single-nucleotide polymorphisms (SNPs) Asp299Gly, Thr399Ile and the CD14 SNPs -159 and -1359 was completed for subjects with periodontal disease compared with control subjects. Two disease populations were investigated: 73 subjects with aggressive periodontitis (AgP; 28 males, 45 females) and 95 males with chronic periodontitis (CP). The TLR4 and CD14 polymorphisms were determined using SNaPshot primer extension with capillary electrophoresis. Comparison of allele and genotype frequencies for each polymorphism was by Fisher's exact test or chi2 analysis. RESULTS The TLR4 Asp299Gly genotype was present in a significantly (p=0.026) lower proportion of AgP subjects (5.5%) compared with control subjects (16.3%). The unadjusted odds ratio for the Asp299Gly genotype to be associated with AgP was 0.30, 95% confidence interval 0.10-0.91. No differences were found in the prevalence of the TLR4 Asp299Gly genotype in men with CP (18.9%) compared with an age-matched control group with no evidence of periodontitis (17%). In addition, there was no difference in the distribution of the CD14 polymorphisms in either the AgP or CP populations studied compared with controls. CONCLUSION It is concluded that in West European Caucasians, the Asp299Gly TLR4 gene polymorphism is associated with a decreased risk of AgP but not CP. Promoter polymorphisms of the CD14 gene, however, did not influence susceptibility to inflammatory periodontitis in the population cohorts studied.

Abstract
OBJECTIVES We investigated the levels of subgingival plaque bacteria and serum IgG responses in patients with type 1 diabetes and non-diabetic controls of comparable periodontal status. MATERIAL AND METHODS Fifty type 1 diabetes patients (mean duration 20.3 years, range 6-41) were age-and gender-matched with 50 non-diabetic individuals with similar levels of periodontal disease. Full-mouth clinical periodontal status was recorded, and eight plaque samples/person were collected and analysed by checkerboard hybridization with respect to 12 species. Homologous serum IgG titres were assessed by checkerboard immunoblotting. In a sub-sample of pairs, serum cytokines and selected markers of cardiovascular risk were assessed using multiplex technology. RESULTS Among the investigated species, only levels of Eubacterium nodatum were found to be higher in diabetic patients, while none of the IgG titres differed between the groups, both before and after adjustments for microbial load. Patients with diabetes had significantly higher serum levels of soluble E-selectin (p=0.04), vascular cell adhesion molecule-1 (VCAM-1; p=0.0008), adiponectin (p=0.01) and lower levels of plasminogen activator inhibitor-1 (PAI-1; p=0.02). CONCLUSIONS After controlling for the severity of periodontal disease, patients with type 1 diabetes and non-diabetic controls showed comparable subgingival infection patterns and serum antibody responses.

Abstract
AIM The purpose of this study was to investigate the relationship between cigarette smoking and the serum levels of folic acid, vitamin B(12) and some haematological variables in patients with periodontal disease. PATIENTS AND METHODS The study base consisted of 88 volunteer patients with periodontal disease, including 45 current smokers in the age range 31-68 years and 43 non-smokers in the range 32-66 years. The clinical parameters included plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL). Folic acid, vitamin B(12) and haematological variables were determined from peripheral blood samples. RESULTS PI, PD and CAL means were significantly higher in smokers than non-smokers (p<0.05). The serum folic acid concentration of smokers was lower than that of non-smokers (p<0.05), whereas the white blood cell count was higher in smokers than in non-smokers (p<0.05). CONCLUSION The results of this study suggest that among patients with periodontal disease the serum folic acid concentration is lower in smokers compared with non-smokers.

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

Abstract
The aim of the present review was to identify the presence of periodontal diseases and the relative importance of known risk factors in Latin American countries. The retrieved data are sparse and inconsistent, lacking information for the majority of the countries. Gingivitis is ubiquitous in the region, affecting all ages independently of the socioeconomic background. The extension of bleeding may vary greatly, ranging from 40% to 70% of sites. The prevalence of aggressive periodontitis is higher in Latin America than in industrialized countries. Prevalence ranges from 0.3% to 4.5%, and the localized form is the less prevalent. The prevalence of chronic periodontitis is high, with a large variation (40-80%) probably due to differences in methodology and diagnostic criteria. Regional differences may be relevant. Known risk factors are present in the populations studied. Non-modifiable factors such as age, gender and genetics have been associated in Brazilian and Chilean populations. Tobacco smoking and diabetes are relevant risk factors. The importance of socioeconomic status, although present as a risk factor, has been largely underestimated. Oral hygiene is extremely deficient in the area although it is a cultural habit in most populations. It can be concluded that periodontal diseases are highly prevalent in Latin American populations. Its prevalence and extent are associated with known risk factors. Oral hygiene habits are deficient. Well designed epidemiological studies with external validity are needed.

Abstract
OBJECTIVE To determine and compare the distribution of Porphyromonas gingivalis fimA genotypes in type 2 diabetes mellitus (T2DM) patients affected by periodontitis, using non-diabetic subjects with and without periodontitis as control groups. MATERIAL AND METHODS This study involved 75 subjects divided into three groups of 25 subjects each: Group 1 (non-T2DM without periodontitis), Group 2 (non-T2DM with periodontitis) and Group 3 (T2DM with periodontitis). The outcome variable was periodontitis, and explanatory variables were age, sex, T2DM and specific P. gingivalis fimA genotypes. RESULTS In non-T2DM subjects with healthy periodontal tissues, type I fimA was the most frequently detected individually (40%) or in combinations (40%). In non-T2DM subjects with periodontitis, the most frequently detected type was Ib individually (20%) or in combinations (36%). In T2DM patients with periodontitis, the most frequently detected types were types I (20%) and III (20%), but there was no statistical difference (p>0.05) with non-T2DM periodontitis subjects. CONCLUSIONS Type I genotype was more frequently detected in periodontally healthy sites from non-T2DM subjects than in periodontitis sites from either subjects with or without T2DM. However, in sites affected by periodontitis from T2DM subjects the predominating types were I and III, which are less virulent strains of P. gingivalis.

Abstract
The microvascular complications of diabetes are serious, and can be life threatening. They involve injury to the blood vessels in the retina, kidney, nervous system, gingiva, and skin. Controlling the risk factors for microvascular complications involves controlling glucose level, blood pressure, and lipids, along with healthy lifestyle changes. Early identification of these complications can promote early interventions and prevent of slow progression of these diseases. Nurses can play a major role through patient care and self-management education.

Abstract
AIM The aim of this study was to evaluate the potential association of the use of smokeless tobacco (moist snuff) on the periodontal conditions of adolescents. MATERIAL AND METHODS A subject sample of one hundred and three 19-year-old male individuals (33 snuff users, 70 controls) living in Göteborg, Sweden, were clinically examined with regard to oral hygiene, gingivitis, probing pocket depth (PPD), clinical attachment loss (CAL) and gingival recession. Bitewing radiographs were obtained for assessments of alveolar bone level. Information about tobacco and oral hygiene habits was obtained by a structured questionnaire. Student 's t-test, chi(2)-test and logistic regression analysis were used for statistical analysis. RESULTS The mean plaque and gingivitis scores in snuff-users were 59% (SD 21.0) and 47% (18.6), respectively, and in controls 64% (22.4) and 50% (18.3), respectively. The average PPD and CAL in snuff-users amounted to 2.3 mm (0.3) and 0.2 mm (0.1), respectively, and in controls 2.4 mm (0.3) and 0.1 mm (0.1) (p>0.05), respectively. The mean bone level was 1.3 mm (0.2) in both groups. The prevalence of subjects showing recession was 42% among snuff-users and 17% among controls (p=0.006). In snuff users, an average of 4% (0.9) of the teeth showed recession, compared with 1% (0.3) in controls (p<0.001). Limiting the analysis to the maxillary anterior tooth region, 33% of the snuff-users and 10% of the controls presented recessions (p=0.002). The use of snuff entailed an OR=5.1 to have gingival recessions. CONCLUSION In the present population sample of adolescents, the use of smokeless tobacco (moist snuff) was not associated with the presence of periodontal disease except for a significantly high prevalence of gingival recessions.

Abstract
BACKGROUND Periodontal diseases are complex disorders that have been associated with multiple risk factors. These disorders are triggered by the accumulation of dental plaque, and the clinical signs are caused by the resultant inflammatory and immune responses. Tissue destruction that defines periodontitis has been linked to excessive production of proinflammatory molecules including matrix metalloproteinases, interleukin-1 beta and prostaglandin E(2). Important risk factors for periodontitis can be grouped into four categories: microbial, systemic, behavioral and local. These risk factors can be considered modifiable or unmodifiable. Controlling risk factors is important in the management of chronic diseases and is a valid strategy for controlling periodontal diseases. Limiting the accumulation of dental plaque is an important part of controlling the development and progression of periodontal diseases. By adhering to a daily oral hygiene regimen that includes brushing, flossing and rinsing, patients play an essential role in disease management. CONCLUSION Patients play an important role in controlling the oral microbial biofilm that is essential to the initiation, development and progression of periodontal diseases. A daily oral hygiene regimen that includes the use of an antimicrobial mouthrinse can modify patients' microbial risk of developing periodontal disease. CLINICAL IMPLICATIONS Patients can help reduce their risk of developing periodontal disease by controlling the accumulation of plaque. This can be accomplished, in part, by adhering to a daily oral hygiene regimen that includes brushing, flossing and using an antimicrobial mouthrinse.

Abstract
BACKGROUND As our understanding of periodontal diseases has increased, it has become clear that certain risk factors are associated with the diseases' incidence, severity and progression. This article focuses on the role of risk assessment and disease management in improving patient outcomes, both in the general population and in specific population groups with an increased risk of developing periodontal disease or with associated comorbidities. TYPES OF STUDIES REVIEWED The author reviewed literature related to the efficacy of risk assessment and periodontal disease management in improving clinical outcomes. In addition, he examined studies demonstrating a link between periodontal disease and specific patient populations and other comorbidities. CONCLUSIONS Risk assessment can help predict a patient's risk of developing periodontal disease and improve clinical decision making. In turn, patient adherence to a self-care oral health regimen is a key component to successful periodontal disease management. CLINICAL IMPLICATIONS The clinical practice of risk assessment may reduce the need for complex periodontal therapy, improve patient outcomes and ultimately reduce oral health care costs. Patients are encouraged to become actively involved in periodontal disease management by following a daily three-step regimen of brushing, flossing and rinsing with an antimicrobial mouthrinse.

Abstract
AIM The objective of this study was to determine whether an association existed between chronic systemic diseases/conditions, risk factors common in old age, and the extent and severity of chronic periodontal disease. MATERIALS AND METHODS Sociodemographic and lifestyle characteristics were examined by contrasting rural, urban-marginal, and urban social environments in Central Mexico. Data were analysed with Analysis of Variance, chi2 tests, and multivariable logistic regression. RESULTS A total of 473 adults 60 years old and over were interviewed; 315 were also examined and underwent laboratory assays (participation rate, 66%); women, 62%; mean age 73+/-8 years; 23% edentulous. The distribution of periodontitis by sociodemographic variables showed differences across locales (73% low-urban, 57% middle-urban, 29% rural). The regression model indicated that periodontitis was more frequently associated with low-urban locale, higher systolic blood pressure, higher body mass index, and worse calculus readings, with an interaction whereby being obese and having a high calculus index was associated with a high probability of having periodontitis. CONCLUSIONS Overall periodontal conditions were fair. While we identified oral, systemic, and social variables that modulated the experience of periodontitis, it would appear that urban, low social class elders appeared to have worse periodontal conditions.

Abstract
This review presents a selected overview of the literature concerning risk factors for periodontitis. That in some individuals gingivitis develops into periodontitis is still a matter of extensive research. Cross-sectional studies of clinical and microbiological factors can be meaningful. Longitudinal studies of the natural history allow analysis of potential factors and conditions that may have an impact on the disease process. At present, several possible risk factors for the initiation and progression of periodontitis have been identified: age, gender, plaque, calculus, existing attachment loss. A consistent finding appears to be genetic predisposition for the development of the disease. In terms of microbiology, several micro-organisms have been identified. The results of the Java Project on natural development of Periodontal Disease clearly pinpoint Actinobacillus actinimycetemcomitans as being associated with the onset of disease. The presence of subgingival calculus was found to be associated with onset and dental plaque with progression of disease. Consistent with literature males are more susceptible to disease. The presence of pockets > or = 5 mm appear to be a useful tool, since it was found to be a prognostic factor for disease progression.
