Abstract
During pregnancy profound perturbations in innate and adaptive immunity impact the clinical course of a number of infectious diseases, including those affecting periodontal tissues. Conversely, it has been suggested that periodontal infections may increase the risk of adverse pregnancy outcomes. In this review, a summary of the literature associated with the bidirectional relationship between pregnancy and periodontal disease as well as the possible mechanisms behind this interaction were examined.

Abstract
BACKGROUND Studies have suggested controversial results regarding a possible association between pre-eclampsia (PE) and periodontal disease (PD) and no meta-analysis has been performed to clarify this issue. METHODS A literature search of electronic databases was performed for articles published through March 24, 2013, followed by a manual search of several dental and medical journals. The meta-analysis was conducted according to the recommendations of the Cochrane Collaboration and PRISMA. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Heterogeneity was assessed with the χ(2)-based Cochran Q test and I(2) statistic. The level of significance was set at P <0.05. RESULTS Fifteen studies were included, including three cohort and 12 case-control studies. A positive association was found between PE and PD (OR 2.17, 95% CI 1.38-3.41, P = 0.0008). However, a high and significant heterogeneity was found (χ(2) = 62.42, P<0.00001, I(2) = 75%). In most cases, subgroup analysis had low power to detect significant differences between PE and non-PE groups. CONCLUSION Based on the findings of the meta-analysis, PD appears to be a possible risk factor for PE. However, given the important differences in the definitions and diagnoses of PD and PE among the studies, as well as their lack of good methodological quality, future trials are needed to confirm the results of the present meta-analysis.

Abstract
Background Many epidemiological studies have found a positive association between periodontal disease (PD) and the risk of preeclampsia, but the magnitude of this association varies and independent studies have reported conflicting findings. We performed a meta-analysis to ascertain the relationship between PD and preeclampsia. Methods The PubMed database was searched up to January 12, 2013, for relevant observational studies on an association between PD and the risk of preeclampsia. Data were extracted and analyzed independently by two authors. The meta-analysis was performed using comprehensive meta-analysis software. Results Thirteen observational case-control studies and two cohort studies, involving 1089 preeclampsia patients, were identified. Based on a random-effects meta-analysis, a significant association between PD and preeclampsia was identified (odds ratio = 2.79, 95% confidence interval CI, 2.01–3.01, P<0.0001). Conclusions Although the causality remains unclear, the association between PD and preeclampsia may reflect the induction of PD by the preeclamptic state, or it may be part of an overall exaggerated inflammatory response to pregnancy. Larger randomized controlled trials with preeclampsia as the primary outcome and pathophysiological studies are required to explore causality and to dissect the biological mechanisms involved.

Abstract
The impact of dietary behaviors and food consumption and their relation to oral health are significant public health issues. Women and men exhibit different dietary behaviors. Understanding the influences of dietary behaviors on oral health from the perspective of gender disparities, however, is limited. This article provides the intersections of dietary factors and oral-systemic health for which women are at greater risk than men. Topics include the effect of dietary choices on oral health disparities seen in female patients. Interventional strategies at the local and community level that are designed to influence the balance between dietary habits and oral-systemic health are discussed.

Abstract
AIM(S) To explore the relationship between biomarkers of systemic inflammation in plasma and gingival crevicular fluid in early pregnancy and the subsequent development of pre-eclampsia in patients with periodontitis. MATERIALS AND METHODS A case-control study was performed. From a cohort composed of 126 pregnant women, 43 normotensive healthy pregnant women were randomly selected, and 11 cases of preeclampsia were identified. Plasmatic and gingival crevicular fluid (GCF) samples were collected in early pregnancy (11-14 wk gestation). The levels of interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were measured in the plasma and GCF samples, whereas the level of C-reactive protein (CRP) was measured in plasma samples. Biomarkers were determined by ELISA assays. The data were analysed using descriptive statistics, and the association between variables was estimated through logistic regression models. RESULTS There was observed an association between pre-eclampsia and plasmatic levels of CRP (OR: 1.07; p = 0.003). Additionally, pre-eclampsia also was associated with IL-6 levels in GCF samples in early pregnancy (OR: 1.05; p = 0.039). A multiple logistic regression model suggests that increased levels of IL-6 in GCF (OR = 1.06; p = 0.02; CI 95% 1.007-1.117) in early pregnancy increase the risk of developing pre-eclampsia. CONCLUSION(S) Pregnant women with periodontitis who later development pre-eclampsia, shows increased levels of IL-6 in GCF and CRP in plasma during early pregnancy. Periodontal disease could contribute to systemic inflammation in early pregnancy via a local increase of IL-6 and the systemic elevation of CRP. Therefore, both inflammatory markers could be involved in the relationship between periodontal disease and pre-eclampsia.

Abstract
Preterm (PT) and Low birth weight (LBW) are considered to be the most relevant biological determinants of newborn infants survival, both in developed and in developing countries. Numerous risk factors for PT and LBW have been defined in the literature. Infections of the genitourinary tract infections along with various biological and genetic factors are considered to be the most common etiological factors for PT/LBW deliveries. However, evidence suggests that sub-clinical infection sites that are also distant from the genitor-urinary tract may be an important cause for PT/LBW deliveries. Maternal periodontal status has also been reported by many authors as a possible risk factor for PT and LBW, though not all of the actual data support such hypothesis. The aim of this paper is to review the evidence from various published literature on the association between the maternal periodontal status and adverse pregnancy outcomes. Although this review found a consistent association between periodontitis and PT/LBW, this finding should be treated with great caution until the sources of heterogeneity can be explained.

Abstract
BACKGROUND Maternal periodontal disease diagnosed by a detailed oral health examination is associated with preeclampsia. Our objective was to measure the association between maternal self-report of oral symptoms/problems, oral hygiene practices, and/or dental service use before or during pregnancy and severe preeclampsia. METHODS A written questionnaire was administered to pregnant females at the time of prenatal ultrasound and outcomes were ascertained by chart abstraction. The χ(2) test compared maternal oral symptoms/problems, hygiene practices, and dental service use between females with severe preeclampsia versus normotensive females. Multivariable logistic regression was used to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for severe preeclampsia. RESULTS A total of 48 (10%) of 470 females reported ≥2 oral symptoms/problems in the 6 months before pregnancy and 77 (16%) since pregnancy. Fifty-one (11%) reported previous periodontal treatment. Twenty-eight (6%) of 470 developed severe preeclampsia. Females with a history of periodontal treatment were more likely to develop severe preeclampsia (aOR = 3.71; 95% CI = 1.40 to 9.83) than females without a history of periodontal treatment. Self-reported oral health symptoms/problems, oral hygiene practices, or dental service use before or during pregnancy were not associated with severe preeclampsia when considered in the context of other maternal risk factors. CONCLUSION Maternal self-report of previous periodontal treatment before pregnancy is associated with severe preeclampsia.

Abstract
BACKGROUND Periodontitis is an inflammatory process caused by a specific group of microorganisms, resulting in the destruction of the tooth-supporting tissue and the resorption of the alveolar bone. Therefore, periodontitis has been considered a risk factor for preeclampsia because infection is one of the factors involved in the etiology and pathogenesis of preeclampsia. The aim of the present study is to determine whether periodontitis is a risk factor for preeclampsia and to identify other possible risk factors. METHODS A case-control study was performed with 574 puerperae under care at the university hospital at the Universidade Federal de Pernambuco in the city of Recife, Brazil. Data collection was preceded by a training exercise and a pilot study. Biologic and socioeconomic data were collected along with medical and dental records. A periodontal examination was performed on all dental elements to determine probing depth and gingival recession. The association between periodontitis and preeclampsia was first adjusted for the variables within each block, and adjusted for the variables of all blocks in the final multivariate model. RESULTS The multivariate logistic regression analysis showed that, after adjustment for other risk factors, periodontitis remained an independent risk factor for preeclampsia (adjusted odds ratio [OR] = 8.60, confidence interval [CI] = 3.92 to 18.88, P < 0.001 and adjusted OR = 2.03, 95% CI = 1.43 to 2.90, P < 0.001, when using the Centers for Disease Control and Prevention/American Academy of Periodontology definition). CONCLUSION The results suggest that within the population studied, periodontitis was a risk factor for preeclampsia.

Abstract
BACKGROUND The findings from the studies on the relationship between periodontal disease and preeclampsia are inconsistent. The objective of this study is to examine the relationship between periodontal disease and preeclampsia. METHODS A multicenter case-control study was conducted in Quebec, Canada. Preeclampsia was defined as blood pressure ≥140/90 mm Hg and ≥1+ proteinuria after 20 weeks of gestation. Periodontitis was defined as the presence of ≥4 sites with a probing depth ≥5 mm and a clinical attachment loss ≥3 mm at the same sites. RESULTS A total of 92 preeclamptic women and 245 controls were analyzed. The percentage of periodontal disease was 18.5% in preeclamptic women and 19.2% in normotensive women (crude odds ratio [OR] = 0.96, 95% confidence interval [CI] = 0.52 to 1.77). After adjusting for confounding variables, periodontitis remained not associated with preeclampsia (adjusted OR = 1.13, 95% CI = 0.59 to 2.17). CONCLUSION This study does not support the hypothesis of an association between periodontal disease and preeclampsia.

Abstract
BACKGROUND There are many studies documenting increased prevalence of periodontal infection in women with preeclampsia. But, very few studies have attempted to establish causal relationship between the two. OBJECTIVE To find out causal circumstantial evidence by isolating specific periodontal pathogens in oral and placental samples. MATERIALS AND METHODS Antenatal periodontal screening and subgingival plaque collection was carried out in ten women with hypertension in pregnancy and ten normotensive controls on their hospital admission at term for cesarean delivery. Placental biopsy was obtained after aseptic placental collection at the time of elective cesarean delivery. Subgingival plaque and placental biopsy were studied for Porphyromonas gingivalis, Fusobacterium nucleatum, Treponema denticola, Prevotella intermedia and Aggregatibacter actinomycetemcomitans using quantitative polymerase chain reaction technique. Periodontist and laboratory personnel were unaware of case or control status. Periodontal status was not informed to the obstetrician recruiting the cases and laboratory. Microbiology report was not revealed till end of the study. RESULTS Periodontal pathogens were found to be high in the group with hypertension than the controls. P gingivalis was found in all the samples from subgingival plaque and placenta, irrespective of the periodontal disease status. CONCLUSION In cases with hypertension, periodontal pathogens are present in higher proportion in subgingival plaque and placenta.

Abstract
Chronic periodontitis is a common inflammatory disorder that is being contemplated as a risk factor for atherosclerotic complications. Current epidemiological evidence also supports its potential association with increases in blood pressure levels and hypertension prevalence. Furthermore, data from cross-sectional studies suggest that in hypertensive subjects periodontitis may enhance the risk and degree of target organ damage. A possible pathogenetic background of an effect of periodontitis on blood pressure should include the systemic generalization of the local oral inflammation, the role of the host immune response, the direct microbial effect on the vascular system and alterations in endothelial function. Inversely, the concept of hypertension unfavorably affecting periodontal tissues cannot be excluded. The two conditions share multiple common risk factors that should be readily controlled for when assessing a possible association. Thoroughly designed prospective and interventional trials are needed in order to determine the impact of periodontitis on blood pressure regulation and incident hypertension and its integration in the clinical approach of both dental and hypertensive patients.

Abstract
PURPOSE To foster an awareness of the need for oral health care as a component of a programme for rehabilitation of individuals with disabilities. METHOD A case study of the USA is used to illustrate the evolving community residential settings for individuals with disabilities and the resulting complexities in the delivery of health services. Examples of oral health conditions frequently present in individuals with disabilities are provided. RESULTS National and local reports indicate that barriers exist in the delivery of oral health services for individuals with intellectual/developmental and later life disabilities. CONCLUSION Oral health care is a component of rehabilitation, as long as attendant pain erodes energy and aspirations of individuals with disabilities. Dental practitioners face many of the same complex difficulties encountered by other health practitioners in the provision of services for individuals with disabilities. The need is for the practitioners in the many health fields to play an important role in developing an awareness of, and referrals for, necessary oral health care.

Abstract
BACKGROUND Maternal periodontal infection is associated with an increased risk for preeclampsia. Periodontal infection is also associated with increased oxidative stress. Our objective was to determine the relationship among maternal periodontal disease, maternal oxidative stress, and the development of preeclampsia. METHODS A secondary analysis of prospectively collected data from the Oral Conditions and Pregnancy Study was performed. A cohort of healthy women enrolled at <26 weeks of gestation underwent an oral examination, serum sampling, and delivery follow-up. A periodontal infection was categorized by clinical parameters as healthy or mild or moderate/severe periodontal infection. Preeclampsia was defined by the American Congress of Obstetricians and Gynecologists criteria as blood pressure >140/90 mmHg and >or=1+ proteinuria on a catheterized specimen. Maternal blood was assayed for 8-isoprostane concentrations using an enzyme-linked immunosorbent assay and stratified as elevated (>or=75th percentile) or not elevated (<75th percentile). Odds ratios (ORs) for preeclampsia were calculated and stratified by periodontal disease and the level of 8-isoprostane concentration. RESULTS A total of 34 (4.3%) of 791 women developed preeclampsia. Women with an 8-isoprostane concentration >or=75th percentile at enrollment were more likely to develop preeclampsia compared to women with an 8-isoprostane concentration <75th percentile (38.2% versus 24.4%, respectively; P = 0.07; OR: 1.91; 95% confidence interval [CI]: 0.94 to 3.90). Among women with moderate/severe periodontal disease, an elevated 8-isoprostane concentration (>or=75th percentile) did not significantly increase the likelihood for preeclampsia (adjusted OR: 2.08; 95% CI: 0.65 to 6.60). CONCLUSIONS Women with oxidative stress early in pregnancy, as measured by an 8-isoprostane concentration >or=75th percentile, were at an increased risk for developing preeclampsia. The presence of periodontal disease did not appear to modify this risk.

Abstract
Dental caries in the primary dentition can have significant damaging effects on a childs growth due to impairment of oral functions. Since the first encounter of a child to a medical environment is often through pediatricians and medical practitioners, it is important that they be aware of the prevention of oral disease that begins early in life. The aim of this article is to diminish the existing ambiguity among pediatricians and medical practitioners regarding oral disease and its prevention.

Abstract
BACKGROUND We examined whether pregnant women with periodontal disease have an increased risk of preeclampsia, and we empirically evaluated the extent to which associations between periodontal disease and preeclampsia are dependent upon diagnostic criteria used to define periodontal disease operationally. METHODS One hundred and fifty preeclampsia cases and one-fifty normotensive controls who delivered a singleton infant at term were enrolled. Periodontal examinations were performed within 48 h after delivery. Participants' periodontal health status was classified, a priori, into four categories according to the extent and severity of periodontal disease. Putative risk factors for periodontal disease and preeclampsia were ascertained during in-person postpartum interviews using a structured questionnaire and by medical record abstraction. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS No clinically meaningful differences were observed between cases and controls with regard to periodontal parameters. After controlling for known confounders, severe clinical periodontal disease was not associated with an increased risk of preeclampsia (OR = 0.92, 95% CI: 0.26-3.28). In addition, there was no evidence of a linear increase in risk of preeclampsia with increasing severity of periodontal disease (P for trend = 0.65). When different diagnostic criteria previously used in other studies were used, the prevalence of periodontal disease varied substantially. However, the magnitude and direction of associations between periodontal disease and preeclampsia were largely similar regardless of the diagnostic criteria used to define periodontal disease. CONCLUSIONS This study provides no convincing evidence that periodontal disease is associated with preeclampsia risk among Thai women.

Abstract
Several studies have suggested an association between maternal periodontal disease and preterm delivery, but this has not been a consistent finding. In 2006-2007, the authors examined the relation between maternal periodontal disease and preterm delivery among 467 pregnant Thai women who delivered a preterm singleton infant (<37 weeks' gestation) and 467 controls who delivered a singleton infant at term (> or =37 weeks' gestation). Periodontal examinations were performed within 48 hours after delivery. Participants' periodontal health status was classified into 4 categories according to the extent and severity of periodontal disease. Logistic regression was used to estimate odds ratios and 95% confidence intervals. Preterm delivery cases and controls were similar with regard to mean probing depth, mean clinical attachment loss, and mean percentage of sites exhibiting bleeding on probing. After controlling for known confounders, the authors found that severe clinical periodontal disease was not associated with an increased risk of preterm delivery (odds ratio = 1.20, 95% confidence interval: 0.67, 2.16). In addition, there was no evidence of a linear increase in risk of preterm delivery or its subtypes associated with increasing severity of periodontal disease (P(trend) > 0.05). The results of this case-control study do not provide convincing evidence that periodontal disease is associated with preterm delivery or its subtypes among Thai women.

Increased TLR4 expression in murine placentas after oral infection with periodontal pathogens. Placenta 2008; 30:156-62.

Abstract
Maternal periodontitis has emerged as a putative risk factor for preterm births in humans. The periodontitis-associated dental biofilm is thought to serve as an important source of oral bacteria and related virulence factors that hematogenously disseminate and affect the fetoplacental unit; however the underlying biological mechanisms are yet to be fully elucidated. This study hypothesized that an oral infection with the human periodontal pathogens Campylobacter rectus and Porphyromonas gingivalis is able to induce fetal growth restriction, placental inflammation and enhance Toll-like receptors type 4 (TLR4) expression in a murine pregnancy model. Female Balb/C mice (n = 40) were orally infected with C. rectus and/or P. gingivalis over a 16-week period and mated once/week. Pregnant mice were sacrificed at embryonic day (E) 16.5 and placentas were collected and analyzed for TLR4 mRNA levels and qualitative protein expression by real-time PCR and immunofluorescence. TLR4 mRNA expression was found to be increased in the C. rectus-infected group (1.98 +/- 0.886-fold difference, P < 0.01, ANOVA) compared to controls. Microscopic analysis of murine placentas showed enhanced immunofluorescence of TLR4 in trophoblasts, mainly in the placental labyrinth layer. Also, combined oral infection with C. rectus and P. gingivalis significantly reduced the overall fecundity compared to controls (16.7% vs. 75%, infected vs. non-infected mice respectively, P = 0.03, Kaplan-Meier). The results supported an enhanced placental TLR4 expression after oral infection with periodontal pathogens. The TLR4 pathway has been implicated in the pathogenesis of preterm births; therefore the abnormal regulation of placental TLR4 may give new insights into how maternal periodontitis and periodontal pathogens might be linked to placental inflammation and preterm birth pathogenesis.

Abstract
OBJECTIVE The objective of this study was to develop a rodent model of Porphyromonas gingivalis infection during pregnancy. STUDY DESIGN Sprague Dawley rats were infected intravenously with 10(5), 10(7), or 10(9) CFU per dam of P gingivalis strain W83, ATCC 33277, or A7436 at gestational day 14 and necropsied at gestational day 18. Maternal organs were cultured to assess the spread of the infection. Six fetal units (placenta, amniotic fluid, membranes, and fetus) per dam were cultured; additional fetal units were examined by histopathology. Polymerase chain reaction was performed on placentas. RESULTS Colonization rates were dependent on the strain of P gingivalis used and the infection dose. At an infection dose of 10(9) CFU/dam, P gingivalis W83, ATCC 33277, or A7436 was detected in 33%, 83%, or 100% of placentas, respectively. Epithelial hyperplasia, cellular necrosis, and inflammatory infiltrate were observed in infected placental tissues. CONCLUSION This study demonstrated that P gingivalis can invade both maternal and fetal tissues, resulting in chorioamnionitis and placentitis.

Abstract
AIM To develop a test for the screening of pregnant women for periodontitis using saliva prior to a dental examination. METHODS A cross-sectional research design was employed. Whole unstimulated saliva was collected from 221 pregnant women prior to a dental examination at the Amagasaki Public Health Office and levels of activity of lactate dehydrogenase (LDH) and alkaline phosphatase (ALP), and of occult blood in the saliva were measured. The data were compared with Community Periodontal Index of Treatment Needs (CPITN) scores. The diagnostic performance of LDH, ALP, and occult blood was determined in terms of sensitivity, specificity, and the area under receiver operating characteristics (ROC) curves. The optimal combination of parameters for screening periodontitis was determined at maximum sensitivity and specificity. RESULTS Periodontitis (CPITN 3, 4) in 19 women (8.6%) and gingivitis (CPITN 1, 2) in 129 women (58.4%) were observed. The activity levels of LDH and ALP were significantly higher in the pregnant women with periodontitis than those with gingivitis or a healthy periodontium. To distinguish between the pregnant women with periodontitis and the others, a cut-off value of 684 IU/L for LDH and of 75 IU/L for ALP were determined by a ROC analysis. The test combining LDH, ALP, and occult blood showed the highest diagnostic performance; with a sensitivity value of 0.90, specificity value of 0.62, positive predictive value of 0.18, and negative predictive value of 0.98. CONCLUSIONS A test combining the parameters salivary LDH, ALP and occult blood is useful for screening pregnant women for periodontitis.

Abstract
OBJECTIVE Maternal periodontal disease, a chronic oral infectious and inflammatory disorder, is associated with an increased risk for preeclampsia. Our objective was to determine the relationship between maternal periodontal disease, maternal systemic inflammation, and the development of preeclampsia. STUDY DESIGN A secondary analysis of data from the Oral Conditions and Pregnancy Study was performed. A cohort of healthy pregnant women enrolled at less than 26 weeks underwent an oral health examination, serum sampling, and delivery follow-up. Periodontal disease was categorized clinically as present or absent. Maternal serum was assayed for C-reactive protein by high-sensitivity enzyme-linked immunosorbent assay and stratified as elevated (> or = 75th percentile) or not elevated (< 75th percentile). Preeclampsia was defined as blood pressure > 140/90 mmHg and at least 1+ proteinuria on a catheterized urine specimen. Risk ratios (RR) for preeclampsia were calculated, stratified by periodontal disease and C-reactive protein level. RESULTS Thirty-one (4%) of 775 women with complete data developed preeclampsia. Women with CRP > or = 75th percentile were more likely than those with CRP < 75th percentile to develop preeclampsia (7% vs 3%, P < .03; RR, 95% CI 2.2, 1.1-4.4). Women with periodontal disease and CRP > or = 75th percentile were at increased risk for preeclampsia (adjusted RR 5.8, 1.2-26.9), compared to women without periodontal disease and either CRP < 75th or > or = 75th percentile. CONCLUSION Maternal periodontal disease with systemic inflammation as measured by C-reactive protein is associated with an increased risk for preeclampsia.

Abstract
There are lingering questions regarding the association between maternal infection and preeclampsia. Systematic review and metaanalysis was conducted of observational studies that examined the relationship between maternal infection and preeclampsia. Forty-nine studies met the inclusion criteria. The risk of preeclampsia was increased in pregnant women with urinary tract infection (pooled odds ratio, 1.57; 95% CI, 1.45-1.70) and periodontal disease (pooled odds ratio, 1.76; 95% CI, 1.43-2.18). There were no associations between preeclampsia and presence of antibodies to Chlamydia pneumoniae, Helicobacter pylori, and cytomegalovirus, treated and nontreated HIV infection, and malaria. Individual studies did not find a relationship between herpes simplex virus type 2, bacterial vaginosis, and Mycoplasma hominis and preeclampsia. Urinary tract infection and periodontal disease during pregnancy are associated with an increased risk of preeclampsia. More studies are required to verify this as well as to explore whether or not such relationships are causal and, if so, the mechanisms involved.

Abstract
UNLABELLED To examine the existing evidence on the relationship between periodontal disease and adverse pregnancy outcomes, we conducted a systematic review of studies published up to December 2006. Studies published in full text were identified by searching computerized databases (e.g., MEDLINE, EMBASE). A meta-analysis was performed to pool the effect size of the clinical trials. Forty-four studies were identified (26 case-control studies, 13 cohort studies, and 5 controlled trials). The studies focused on preterm low birth weight, low birth weight, preterm birth, birth weight by gestational age, miscarriage or pregnancy loss, preeclampsia, and gestational diabetes mellitus. Of the chosen studies, 29 suggested an association between periodontal disease and increased risk of adverse pregnancy outcome (odds ratios [ORs] ranging from 1.10 to 20.0) and 15 found no evidence of an association (ORs ranging from 0.78 to 2.54). A meta-analysis of the clinical trials suggested that oral prophylaxis and periodontal treatment may reduce the rate of preterm low birth weight (pooled risk ratio (RR): 0.53, 95% confidence interval [CI]: 0.30-0.95, P < 0.05), but did not significantly reduce the rates of preterm birth (pooled RR: 0.79, 95% CI: 0.55-1.11, P > 0.05) or low birth weight (pooled RR: 0.86, 95% CI: 0.58%1.29, P > 0.05). The authors conclude that periodontal disease may be associated with increased risk of adverse pregnancy outcomes. More methodologically rigorous studies are needed in this field. Currently, there is insufficient evidence to support the provision of periodontal treatment during pregnancy for the purpose of reducing adverse pregnancy outcomes. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to state that the published literature is not vigorous to clinically link periodontal disease and/or its treatment to specific adverse pregnancy outcomes, and explain that more rigorous studies with world-wide agreed-upon definitions are particularly needed before periodontal disease treatment can be recommended.

Abstract
BACKGROUND Epidemiologic and randomized controlled studies have shown that periodontal diseases may be associated with preterm labor and delivery of infants with low birth weights. The purpose of the present study was to determine the presence of microbial invasion of the amniotic cavity by periodontopathic bacteria in pregnant women with a diagnosis of threatened premature labor. METHODS A periodontal examination and collection of amniotic fluid and subgingival plaque samples were performed on women identified as having threatened premature labor (preterm premature rupture of membranes without clinical infection or labor and preterm labor with intact membranes) and a gestational age ranging between 24 and 34 weeks. Samples collected from amniotic fluid and from the four deepest periodontal pockets in each patient were pooled in prereduced transport fluid and cultured. Porphyromonas gingivalis was identified primarily by colony morphology under stereoscopic microscope and rapid biochemical tests. Amniotic fluid or plaque samples were homogenized, DNA was extracted, and polymerase chain reaction (PCR) amplification of 16S rRNA with specific and universal primers was carried out. RESULTS Twenty-six women with threatened premature labor were included: eight with preterm premature rupture of membranes and 18 with preterm labor with intact membranes. Eight women presented with gingivitis, 12 with chronic periodontitis, and six without periodontal disease. Microbial invasion of the amniotic cavity as detected by P. gingivalis PCR was 30.8% (eight of 26 patients). In these eight patients, P. gingivalis was present in both the subgingival samples and the respective amniotic fluid sample. CONCLUSION The presence of microbial invasion of the amniotic cavity by P. gingivalis could indicate a role for periodontal pathogenic bacteria in pregnant women with a diagnosis of threatened premature labor.

Abstract
BACKGROUND The aim of this study was to investigate the total antioxidant capacity, superoxide dismutase and glutathione peroxidase activities, and malondialdehyde levels in serum, saliva, and gingival crevicular fluid (GCF) in preeclamptic and normotensive pregnant women with and without periodontal disease. METHODS Forty pregnant women, consisting of 10 preeclamptic subjects with periodontal disease, 10 preeclamptic periodontally healthy subjects, 10 normotensive subjects with periodontal disease, and 10 normotensive periodontally healthy subjects, were included in this study. After clinical measurement and samplings, total antioxidant capacity, superoxide dismutase, glutathione peroxidase activities, and malondialdehyde levels in serum, saliva, and GCF of preeclamptic and normotensive pregnant women were determined, and the data were tested by non-parametric tests. Total antioxidant capacity of the clinical samples was measured using a novel automated colorimetric measurement method. Superoxide dismutase and glutathione peroxidase activities and malondialdehyde levels were determined spectrophotometrically. RESULTS Superoxide dismutase and glutathione peroxidase activities in GCF and serum and total antioxidant capacity in saliva, GCF, and serum were the lowest in preeclamptic women with periodontal disease. However, serum and GCF levels of malondialdehyde were the highest in this group of pregnant women. CONCLUSIONS Systemic and local antioxidant and total antioxidant capacities are affected by periodontal disease in addition to the impact of preeclamptic status. Similar comments may be made for the increases in systemic and local malondialdehyde levels.

Abstract
AIM To evaluate the possible link between the severity of periodontal disease and pre-eclampsia and to correlate this link to clinical periodontal parameters and interleukin (IL)-1beta, tumour necrosis factor-alpha (TNF-alpha), and prostaglandins (PGE(2)) levels in both gingival crevicular fluid (GCF) and serum. MATERIAL AND METHODS Fifty-nine pregnant women (20 mild pre-eclampsia, 18 severe pre-eclampsia, and 21 healthy pregnant women) were included in the study. Dental and periodontal recordings as well as GCF and blood samples were obtained within 48 h preceding delivery. RESULTS The results of multivariate logistic regression showed a highly significant association between mild to severe pre-eclampsia and severe periodontal disease (p<0.001). After adjusting for potential confounders (smoking, body weight, socioeconomic status, education level, and age), severe pre-eclamptic women were 3.78 (1.77-12.74) times more likely to present severe periodontal disease than normotensive pregnant women. This odds ratio (OR) was 2.43 (1.13-8.19) for mild pre-eclamptic women. IL-1beta, TNF-alpha, and PGE(2) levels in both serum and GCF were also significantly higher in the pre-eclamptic groups than the normotensive women. CONCLUSIONS These results indicate that the presence and severity of periodontal disease seems to increase the risk for not only the occurrence but also the severity of pre-eclampsia in pregnant women.

Abstract
OBJECTIVE Recent studies have shown that pre-eclamptic women present a high prevalence of periodontitis, suggesting that active periodontal disease may play a role in the pathogenesis of pre-eclampsia. The present study analysed the effect of periodontal disease in the concentrations of serum high-sensitivity C-reactive protein (hs-CRP), and its association with pre-eclampsia. METHODS A case-control study was carried out in Cali-Colombia, comprised of 398 pregnant women (145 cases and 253 controls) who were believed to have periodontal disease, between 28 and 36 weeks of gestational age. Pre-eclampsia cases were defined as blood pressure > or = 140/90 mmHg and proteinuria > or = 0.3 g/24 h. Controls were pregnant women with normal blood pressure, without proteinuria, matched by maternal age, gestational age and body mass index. Sociodemographic data, obstetric risk factors, periodontal state, subgingival microbial composition and hs-CRP levels were determined in both groups. RESULTS The case and control groups were comparable for sociodemographic characteristics. In women with pre-eclampsia and confirmed periodontal disease (n = 138), hs-CRP levels increased according to the severity of the disease (gingivitis median 4.14 mg/dl; mild periodontitis median 4.70 mg/dl; moderate/severe periodontitis median 8.8 mg/dl; P = 0.01). A similar tendency was observed in controls with periodontal disease (n = 251), but it did not reach statistical significance (gingivitis median 5.10 mg/dl; mild periodontitis median 5.12 mg/dl; moderate/severe periodontitis median 6.90 mg/dl; P = 0.07). A significant difference in hs-CRP levels was observed in pre-eclamptic women with moderate/severe periodontitis compared to controls (P = 0.01). CONCLUSION These findings suggest that chronic periodontitis may increase hs-CRP levels in pregnant women and lead to complications such as pre-eclampsia.

Abstract
OBJECTIVES A growing body of evidence suggests an association between maternal infection and preeclampsia. To examine the strength of this association, we conducted a comprehensive review of studies published in peer-reviewed journals. METHODS Data collection for this review involved Medline, Embase, and Cochrane data base searches of published studies since 1964 on the relationship between maternal infection and preeclampsia. Data were abstracted according to predefined inclusion and exclusion criteria. Study population included women with preeclampsia and normotensive mothers with and without bacterial or viral infections. Altogether, thirty two original studies were identified and evaluated for methodological quality, preeclampsia diagnosis and adjustment for well-known preeclampsia confounders. Pooled odds ratios and 95% confidence intervals, according to infection status, were calculated using DerSimonian-Laird random-effects models. Publication bias was assessed with a funnel plot and Egger's regression asymmetry test. RESULTS Sixteen of the 32 studies evaluated were selected for inclusion in the meta-analysis. These studies showed that women with either a bacterial or viral infection were at higher risk of developing preeclampsia, compared to women without infection. Combined results for the 16 studies yielded an OR of 2.1 (95% CI 1.6-2.7). Separate pooled estimates for prospective (OR 2.3, 95% CI 1.7-3.0), case control and retrospective studies combined (OR 2.0, 95% CI 1.4-2.9) yielded similar results. Heterogeneity was significant across overall pooled estimates, case control and retrospective studies (Q(df=20) of 45.7, P = .001; Q(df=10) of 38.7, P < .005, respectively), but not prospective studies (Q(df=9) of 6.5 P = .69). CONCLUSIONS In our analysis, any infection (bacterial or viral) was associated with a two-fold higher risk of preeclampsia. This association may provide a potential explanation for preeclampsia-related inflammation.

Abstract
BACKGROUND Periodontal disease is a chronic inflammatory infectious disease that may act as a focus of infection. Preeclampsia is a pregnancy-specific hypertensive disorder that often leads to maternal morbidity and mortality. Acute atherosis, the placental lesion of preeclampsia, shares many histopathological features with atherosclerosis. Recently, chronic infection was linked to the initiation of atherosclerosis. Oral pathogens have been detected in atherosclerotic plaques, where they may play a role in the development and progression of atherosclerosis. The purpose of the present study was to explore the possibility that periopathogenic bacteria may translocate into the placental tissues of women with preeclampsia. METHODS Samples were taken from 16 placentas obtained from cesarean sections of women with preeclampsia and from 14 age-matched healthy pregnant women. Polymerase chain reaction was used to detect Actinobacillus actinomycetemcomitans, Fusobacterium nucleatum ssp., Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythensis, and Treponema denticola. RESULTS Eight of the 16 (50%) placenta specimens were positive for one or more periopathogenic bacteria in the preeclampsia group, compared to only two of the 14 samples (14.3%) from controls. Bacterial counts were statistically significantly higher in the preeclampsia group for all of the periopathogenic bacteria examined (P <or=0.0055). Although all of the target periopathogenic bacteria were found in the preeclampsia group, only three (P. gingivalis, T. forsythensis, and T. denticola) were found in the control group. CONCLUSION The significant presence of periopathogenic microorganisms or their products in human placentas of women with preeclampsia may suggest a possible contribution of periopathogenic bacteria to the pathogenesis of this syndrome.

Abstract
OBJECTIVE Pre-eclampsia is a complication of pregnancy characterized by systemic vascular dysfunction and pathological changes in placental arteries. Growing evidence of chronic infection as an aetiological factor in vascular diseases prompted us to study maternal periodontal disease in subjects with early-onset pre-eclampsia (<34 weeks). METHODS A case-control study was carried out on 17 early-onset pre-eclamptic women and 35 controls with uncomplicated pregnancies in a period of 3-28 months postpartum. All were Caucasians. Full-mouth periodontal examinations were performed to determine the periodontal condition. Subgingival-plaque samples were analysed by anaerobic culture techniques for the presence of seven bacterial periodontal pathogens. Potential confounders as age, smoking, educational level and body mass index were determined. RESULTS Severe periodontal disease was found in 82% of the pre-eclamptic and in 37% of the control group (p=0.009). After adjusting for age, smoking and educational level, the odds ratio was 7.9 (95% CI: 1.9-32.8). The periodontopathic microorganism Micromonas micros was more prevalent in the case group (p=0.040) while Campylobacter rectus was more prevalent in the control group (p=0.047). CONCLUSION These results indicate that Caucasian women with a recent history of early-onset pre-eclampsia have a worse periodontal condition, as compared with women with uncomplicated deliveries.
