Abstract
BACKGROUND During pregnancy, dental plaque-induced gingivitis prevalence and subsequent risk of periodontal disease increases substantially, as a consequence of both inadequate oral hygiene and changes in sex steroid hormone levels. Although maternal periodontal disease has been associated with adverse pregnancy outcomes, including spontaneous preterm birth, previous clinical trials involving mechanical debridement (eg, scaling and root planing) to remove plaque biofilm have not yielded decreased rates of preterm birth. OBJECTIVE We hypothesized that an advanced oral hygiene program, including an antibacterial regimen coupled with a power toothbrush and hygiene instruction, may improve the periodontal milieu and reduce the rate of spontaneous preterm birth. Therefore, we conducted a clinical trial of obstetrical patients with moderate-to-severe gingivitis who were randomized to an advanced oral hygiene program vs usual oral hygiene care, and the primary obstetrical outcome compared between the treatment groups was gestational age at delivery. STUDY DESIGN Obstetrical patients with singleton pregnancies between 8 and 24 weeks' gestation were screened by trained dentists at 2 clinical sites for moderate-to-severe gingivitis (>30 intraoral sites with gingival bleeding on probing). Eligible participants were randomized to an advanced oral hygiene regimen, including antibacterial mouth wash, dental floss, antibacterial toothpaste, a power toothbrush, and intensive oral hygiene education vs standard oral home care instructions and regimen. The primary obstetrical outcome assessed was gestational age at delivery. The overall primary (dental) outcomes were gingival index, bleeding sites, and pocket depth (reported elsewhere). Secondary obstetrical outcomes included birthweight and incidence of preterm birth at <37 weeks' gestation. Regression models were utilized and included factors such as treatment group, gestational age at enrollment, preterm birth history, and potential markers of health disparities (ie, education, employment status). RESULTS A total of 817 obstetrical patients underwent dental screening at the 2 sites, 789 were identified with moderate-to-severe gingivitis, 746 were randomized, and birth outcomes were available for 613 of the study participants. The gestational age at delivery was 2 days earlier in the control group (P=.040), but the clinical significance of this finding was limited (39.13 vs 38.85 weeks). Overall rates of spontaneous preterm birth <37 weeks and <34 weeks were not statistically different between the 2 treatment groups (7.0% advanced oral hygiene regimen vs 10.3% controls, OR=1.63 (0.90-3.00), P=.11; and 2.3% vs 3.9%, OR=1.88 (0.71-4.98), P=.20, respectively). However, we observed lower rates of spontaneous preterm birth among unemployed participants with less favorable socioeconomic status (4.7% advanced oral hygiene regimen vs 16.0% controls, OR=4.04 (1.34-15.12), P=.01). CONCLUSION An advanced oral hygiene program may reduce the risk of spontaneous preterm birth among pregnant patients with moderate-to-severe gingivitis and health disparities. This is the same group that may be at highest risk of poor dental hygiene and preterm birth.

Abstract
Inflammation is associated with preterm birth. We previously described a mouse model of chronic inflammation-induced preterm birth after dental Porphyromonas gingivalis infection. The aim of this study was to employ this model system to investigate the mechanisms through which enhanced uterine contractility induces preterm birth. Messenger RNA (mRNA) encoding contraction-associated proteins, such as oxytocin receptors, was measured at various gestational time points by real-time polymerase chain reaction (PCR). Spontaneous and oxytocin-induced uterine contractile activity at gestational day 18 was assessed using a tissue organ bath. The expression levels of Toll-like receptor 2 (TLR2), TLR4, cyclooxygenase (COX)-2, nuclear factor-kappa B (NF-κB) p65, and p38 mitogen-activated protein kinase (MAPK) on gestational day 18 were also determined by real-time PCR or Western blotting. Messenger RNA encoding contraction-associated proteins was increased at gestational day 18, and the spontaneous contractile activity (1.6-fold greater area under the contraction curve) and sensitivity to oxytocin (EC50: 8.8 nM vs 2.2 nM) were enhanced in the P gingivalis group compared to those in the control group. In the P gingivalis group, COX-2 mRNA expression was not elevated in the placenta or myometrium but was upregulated 2.3-fold in the fetal membrane. The TLR2 mRNA levels in the fetal membrane were 2.7-fold higher in the P gingivalis group, whereas TLR4 levels were not elevated. Activation of the NF-κB p65 and p38 MAPK pathways was enhanced in the fetal membrane of the P gingivalis group. Thus, in mice with chronic dental P gingivalis infection, TLR2-induced inflammation in the fetal membrane leads to upregulation of uterine contractility, leading to preterm birth.

Abstract
Oral health is a fundamental component of health and physical and mental well-being. Oral health is influenced by an individual's physiologic and psychosocial attributes and cumulative oral health experiences. The perinatal period is a critical time when health and oral health determinants set in and thus an important time for intervention. Recognition of the importance of oral health intervention during pregnancy and oral health infrastructures have substantially grown over the last several years. This article reviews the current state of knowledge and practice of oral health intervention during pregnancy with a focus on individual- and population-based strategies, and summarizes key agendas for advancing prenatal oral health.

An Umbrella Review Exploring the Effect of Periodontal Treatment in Pregnant Women on the Frequency of Adverse Obstetric Outcomes. J Evid Based Dent Pract 2017; 18:218-239. [PMID: 30077375 DOI: 10.1016/j.jebdp.2017.10.011] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2017] [Revised: 10/27/2017] [Accepted: 10/27/2017] [Indexed: 12/22/2022]
Abstract
OBJECTIVE In the recent years, efforts have been made to reduce epidemiologic indicators of periodontal disease in pregnant women. This umbrella review aims to analyze the systematic reviews/meta-analyses investigating the effect of periodontal therapy in pregnant women on the frequency of obstetric complications (low birth weight, preterm delivery, and preeclampsia) and to identify the gaps in the scientific literature. METHODS A systematic review of systematic reviews with and without meta-analysis of intervention studies was conducted. Quality evaluation and qualitative analysis of the reviews were performed. RESULTS A total of 223 articles were obtained, and 18 of them were included in the analysis, 13 articles included meta-analysis, where 11 were of high quality and 7 of medium quality according to the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guide. These systematic reviews/meta-analyses included a total of 19 studies (17 randomized clinical trials). Descriptive systematic reviews showed that periodontal therapy has positive effects on reducing the frequency of adverse pregnancy outcomes. In systematic reviews with meta-analysis, overall effect estimators were not significant, although a reduction in the incidence of obstetric complications was observed. Subgroup analysis resulted in significant effects, depending on sociodemographic conditions. CONCLUSIONS Differential findings are not enough to demonstrate that there is a significant reduction in the frequency of adverse pregnancy outcomes in pregnant women receiving periodontal therapy. Possible explanations are related to factors such as the type of studies analyzed, indicator of obstetric complication considered, and specific variables included in the analysis. Many systematic reviews did not address publication bias and did identify gaps in knowledge that require further clarification.

Abstract
Over the last two decades there has been a renewed interest around the possible effects of periodontal disease on both cardiovascular health and pregnancy outcome (among other diseases), a topic which has interested science for hundreds of years. These have led to a range of studies, workshops and consensus documents being published, with corresponding coverage in general and professional media. In this article the authors summarise the history and supporting theories behind such associations, whether clinical studies have been able to confirm these and what this might mean for general practitioners who are questioned on this topic by patients.

Abstract
OBJECTIVES The objective of this study was to identify the DNA of oral bacteria in placental samples from women with and without periodontitis who had or had not had preterm births and/or low birthweight (PB/LBW) neonates. METHODS Data were gathered from 57 puerperal women in relation to socio-demographic, gynaecological, and periodontal variables and to placental histomorphology. Fifty-seven biopsies, 28 from mothers with periodontitis, were taken aseptically from preterm placentas (n = 36) and from full-term placentas (n = 21). Total DNA was extracted, and the presence of 15 oral bacteria was assessed using Nested-PCR. RESULTS The placentas from women with periodontitis showed a higher prevalence of periodontopathogens compared to those from women without periodontitis (P = 0.009). Samples showed low prevalences of Actinomyces israelii, Parvimonas micra and Tannerella forsythia. An association was found between Eikenella corrodens in placenta and periodontitis (P = 0.002). The most ubiquitous bacterium, Fusobacterium nucleatum, was more prevalent in mothers with periodontitis and PB/LBW (P = 0.033). Porphyromonas gingivalis, Treponema denticola, Prevotella intermedia and Aggregatibacter actinomycetemcomitans were not detected. CONCLUSIONS These results, along with previous findings, show that oral bacteria may be normally present in the placenta, however, the levels of certain oral pathogens in the placenta would highly depend on the mother's periodontal state.

Abstract
The receptors of the innate immune system have evolved to recognize pathogenic bacteria in a complex manner. Out of these immune receptors, the pattern recognition receptors (PRRs) such as Toll like receptors have gained importance off late to play a key role in the activation of cascade of inflammatory cytokines in pathogenesis of preterm birth. Preterm birth has become leading cause of neonatal deaths globally. The concept of oral infection influencing the occurrence of preterm delivery has gained importance. Translocation of periodontal pathogens and inflammatory mediators play role in the pathogenesis of preterm labour. The transmembrane toll like receptors of innate immunity have been recently implicated in the association of periodontal infection and preterm labour. The TLRs are considered as a key marker and TLR blockade can be a critical method for treating women who are exposed to periodontal pathogens. This review is aimed at discussing the role of TLR in periodontal disease and its relationship with preterm birth.

Periodontal treatment for preventing adverse pregnancy outcomes: a meta- and trial sequential analysis. PLoS One 2015; 10:e0129060.

Abstract
OBJECTIVES Periodontal treatment might reduce adverse pregnancy outcomes. The efficacy of periodontal treatment to prevent preterm birth, low birth weight, and perinatal mortality was evaluated using meta-analysis and trial sequential analysis. METHODS An existing systematic review was updated and meta-analyses performed. Risk of bias, heterogeneity, and publication bias were evaluated, and meta-regression performed. Subgroup analysis was used to compare different studies with low and high risk of bias and different populations, i.e., risk groups. Trial sequential analysis was used to assess risk of random errors. RESULTS Thirteen randomized clinical trials evaluating 6283 pregnant women were meta-analyzed. Four and nine trials had low and high risk of bias, respectively. Overall, periodontal treatment had no significant effect on preterm birth (odds ratio [95% confidence interval] 0.79 [0.57-1.10]) or low birth weight (0.69 [0.43-1.13]). Trial sequential analysis demonstrated that futility was not reached for any of the outcomes. For populations with moderate occurrence (< 20%) of preterm birth or low birth weight, periodontal treatment was not efficacious for any of the outcomes, and trial sequential analyses indicated that further trials might be futile. For populations with high occurrence (≥ 20%) of preterm birth and low birth weight, periodontal treatment seemed to reduce the risk of preterm birth (0.42 [0.24-0.73]) and low birth weight (0.32 [0.15-0.67]), but trial sequential analyses showed that firm evidence was not reached. Periodontal treatment did not significantly affect perinatal mortality, and firm evidence was not reached. Risk of bias, but not publication bias or patients' age modified the effect estimates. CONCLUSIONS Providing periodontal treatment to pregnant women could potentially reduce the risks of perinatal outcomes, especially in mothers with high risks. Conclusive evidence could not be reached due to risks of bias, risks of random errors, and unclear effects of confounding. Further randomized clinical trials are required.

Abstract
BACKGROUND Evidence suggests that periodontitis is associated with prevalent and incident type 2 diabetes mellitus (T2DM), raising the question of whether periodontitis treatment may improve glycemic control in patients with T2DM. Meta-analyses of mostly small clinical trials suggest that periodontitis treatment results in a modest reduction in glycosylated hemoglobin (Hb) A1c. PURPOSE The purpose of the Diabetes and Periodontal Therapy Trial (DPTT) was to determine if periodontal treatment reduces HbA1c in patients with T2DM and periodontitis. METHODS DPTT was a phase-III, single-masked, multi-center, randomized trial with a planned enrollment of 600 participants. Participants were randomly assigned to receive periodontal treatment immediately (Treatment Group) or after 6 months (Control Group). HbA1c values and clinical periodontal measures were determined at baseline and 3 and 6 months following randomization. Medication usage and dosing were assessed at each visit. Periodontal treatment consisted of scaling and root planing for a minimum of two 90-minute sessions, plus the use of an antibacterial mouth rinse for at least 32 days afterwards. The primary outcome was change in HbA1c from baseline to 6 months and the trial was powered to detect a between-group difference of 0.6%. Secondary outcomes included changes in periodontal clinical measures, fasting plasma glucose, the Homeostasis Model Assessment (HOMA2) and the need for rescue diabetes or periodontal therapy. CONCLUSION Dental and medical researchers collaborated to recruit, treat and monitor participants with two chronic diseases to determine if treatment of one condition affects the status of the other.
