Examining the Safety of Dental Treatment in Pregnant Women

Role of periodontal treatment in pregnancy gingivitis and adverse outcomes: a systematic review and meta-analysis

BACKGROUND

Pregnancy gingivitis is a common oral health issue that affects both maternal and fetal health. This study aims to evaluate the effectiveness of periodontal treatment in preventing pregnancy gingivitis, preterm birth, and low birth weight through a systematic review and meta-analysis of randomized controlled trials (RCTs).

METHODS

A systematic review and meta-analysis were conducted following PRISMA guidelines. A comprehensive literature search was performed across CINAHL, Scopus, Cochrane, and PubMed/Medline databases from 2000 to the present. Study selection and data extraction were independently carried out by two reviewers. Statistical analyses, including heterogeneity tests, sensitivity analysis, and publication bias assessment, were conducted using RevMan 5.4 and R software.

RESULTS

A total of 13 studies were included. The meta-analysis indicated that periodontal treatment might have a potential effect on preventing pregnancy gingivitis, but this was not statistically significant (OR = 0.85, 95% CI [0.68, 1.06], I2 = 51%). Subgroup analysis revealed that periodontal treatment significantly reduced the rates of preterm birth and low birth weight in lower-quality studies, but no significant effects were observed in higher-quality studies. Sensitivity analysis and publication bias tests confirmed the stability and reliability of the results.

CONCLUSION

While lower-quality studies suggest that periodontal treatment may positively impact pregnancy gingivitis, preterm birth, and low birth weight, these effects were not supported by higher-quality evidence. Further well-designed RCTs are needed to confirm these findings and ensure their reliability. Periodontal treatment could potentially be considered as part of prenatal care to improve maternal oral health and pregnancy outcomes.

Systemic Factors Affecting Orthodontic Treatment Outcomes and Prognosis-Part 2

This article explores the various challenges systemic conditions can pose before and during orthodontic treatment. Cardiovascular conditions like infective endocarditis require antibiotic prophylaxis before certain orthodontic procedures are started. Patients with bleeding disorders require special considerations in regards to viral infection risk and maintenance of excellent atraumatic oral hygiene. Orthodontists play an important role in early identification of signs and symptoms of eating disorders and should deal with these patients sensitively. Congenital disorders, craniofacial anomalies, and nutritional deficiencies require special considerations and should be addressed appropriately before orthodontic treatment is started.

Effects of different periodontal interventions on the risk of adverse pregnancy outcomes in pregnant women: a systematic review and network meta-analysis of randomized controlled trials

Background

Periodontal disease is widespread among pregnant women, and it is possible that taking action to improve oral health conditions can make improvements in adverse pregnancy outcomes. Herein, we summarize the recent evidence using a network meta-analysis to assess the effects of different periodontal treatment intervention strategies on the risk of adverse pregnancy outcomes in pregnant women.

Materials and methods

Randomized controlled trials were retrieved from PubMed, Web of Science, Embase, and Cochrane Library databases. After literature screening, data extraction, and quality evaluation of the included literature were performed, the R studio 4.2.2 "netmeta" package was used for the network meta-analysis.

Results

A total of 20 studies were included, and 5 adverse pregnancy outcomes (preterm birth, low birth weight, preterm birth and/or low birth weight infants, small for gestational age, and pre-eclampsia) were considered to examine the effects of different periodontal treatment interventions strategies on the risk of the abovementioned outcome indicators. The results of the network meta-analysis demonstrated that the three periodontal treatment intervention strategies of sub- and/or supra-gingival scaling and root planing + chlorhexidine rinsing (SRP + CR), sub- and/or supra-gingival scaling and root planing+chlorhexidine rinsing + tooth polishing and plaque control (SRP + CR + TP), and sub- and/or supra-gingival scaling and root planing +sonic toothbrush + tooth polishing and plaque control (SRP + ST + TP) reduced the risk of preterm birth [odds ratio (OR) = 0.29, 95% confidence interval (CI) (0.10-0.88), OR = 0.25, 95CI% (0.10-0.63), OR = 0.28, 95CI% (0.11-0.69), respectively]. In addition, two periodontal treatment intervention strategies, SRP + CR and SRP + CR + TP, were effective methods in terms of the risk of preterm birth and/or low birth weight [OR = 0.18, 95CI% (0.06-0.52), OR = 0.31, 95CI% (0.12-0.79)].

Conclusion

The available evidence suggests that the risk of preterm birth and preterm birth and/or low birth weight can be reduced with certain periodontal treatment intervention strategies. Future studies should focus on optimizing intervention strategies and the optimal timing for different periods of pregnancy, in order to provide a reference for pregnant women's healthcare.

Oral Health Literacy Status, Knowledge Levels, Beliefs, and Behaviors of Pregnant Women

CONTEXT

Pregnancy may exacerbate the frequency and severity of some dental problems. However, most pregnant women avoid going to the dentist.

AIMS

To examine the oral hygiene and dental care behaviors of women during pregnancy, to measure their knowledge levels, to reveal their oral and dental health literacy status, and their beliefs about treatment.

SETTINGS AND DESIGN

The study was conducted for a period of 1 month with pregnant women over the age of 18 who presented to the obstetrics outpatient clinic and agreed to participate in the study and who had no known anomalies or complications.

METHODS AND MATERIAL

A survey was completed by face-to-face interviews with 317 pregnant women of different ages and gestational weeks. Participants were asked questions regarding their sociodemographic characteristics, pregnancy characteristics, oral hygiene-related beliefs, behaviors, and knowledge levels.

STATISTICAL ANALYSIS USED

The data obtained in the study were analyzed with SPSS 21.0 program. Since the kurtosis and skewness values were between +3 and -3, parametric tests were used.

RESULTS

In total, 317 pregnant women between the ages of 18 and 43 participated in the study. The most common beliefs are listed as; babies receive the necessary calcium from the teeth, antibiotics given during dental treatment harm the baby, and panoramic radiography taken during treatment harms the baby. 91.5% of the participants did not visit the dentist after planning a pregnancy, and 89% of them did not visit the dentist during pregnancy. The most common reason not to visit the dentist is not having a dental problem. The rate of knowing that dental infections during pregnancy will affect the baby is 50.5%.

CONCLUSIONS

In the present study, it is seen that pregnant women do not have adequate oral hygiene. The reasons were listed as various false beliefs and lack of sufficient knowledge. Health professionals should provide information about oral hygiene to pregnant women and direct them to the dentist.

Treatment Perception and Utilization of Dental Care During Pregnancy Among Women Visiting Antenatal Clinics in King Abdulaziz Medical City & Primary Healthcare, National Guard, Jeddah, Saudi Arabia

Objectives To identify how readily accessible dental care is to a sample of pregnant women in King Abdulaziz Medical City (KAMC), Jeddah, and to determine any potential obstacles to receiving dental care while pregnant. Methodology Female patients visiting antenatal clinics in KAMC in Jeddah, Saudi Arabia were the target group for this cross-sectional study. The age range was limited to childbearing age (18-48 years old). Both pregnant and non-pregnant women were established in obstetrics and gynecology clinics. The pattern of dental service use and attitude toward dental treatment during pregnancy were assessed using a self-administered questionnaire. Other data were gathered, such as demographics, education, employment status, and the number of live births. Results This study included 361 participants in the survey with an 80% response rate. A large proportion of participants was in the age group of 19 to 35 years old (75.07%; p-value < 0.0001), holding undergraduate degrees (58.17%; p-value < 0.0001), housewives (77.56%; p-value < 0.0001), married (99.45%; p-value < 0.0001), non-pregnant women (75.07%; p-value < 0.0001), and have three or more children (42.94%; p-value < 0.0001). About two-thirds of the participants reported using private hospitals for their dental services (65.37%; p-value < 0.0001), while 22.03% (p-value < 0.0001) of the participants reported visiting a dentist in the last six months and 7.2% (p-value < 0.0001) visited a dentist during pregnancy. In terms of awareness questions, 72.02% (p-value < 0.0001) reported that if the mother did not eat well, the baby takes calcium from the mother's teeth, 43.77% (p-value < 0.0001) reported brushing teeth at least three times a day, and 42.94% (p-value < 0.0001) of women reported that they do not have an idea about what they need to do if a pregnant woman needs treatment that requires taking X-rays. Similar patterns were observed in other awareness answers. Conclusion Based on the study's findings, there is a significantly low rate of dental care utilization in the sample of pregnant women. We conclude that educated women are more likely to maintain good oral hygiene and are more satisfied with their oral health. However, a large proportion of participants reported dental problems during their pregnancy. In general, a lack of knowledge about the safety of dental care during pregnancy is the main obstacle to seeking dental care. Limitations The selected sample was from antenatal clinics in KAMC & Primary Healthcare, National Guard, Jeddah, Saudi Arabia. As a result, the findings of this study cannot be applied to the total female population of Jeddah, Saudi Arabia. Because the information was self-reported, which is a common issue with self-administered questionnaires, and because participation in the study was voluntary and participant confidentiality was maintained, there is a low chance that the data may be subject to recall or response bias.

Latest Concepts in Endodontic Management of Pregnant Patients

Pregnant patients and how to manage their treatments is one of the most important challenges in endodontic practice. Endodontic treatment on pregnant women is sometimes an emergency condition to control toothache due to irreversible pulpitis and odontogenic infection. Tooth decay, oral health, local and general anesthesia, analgesics, antibiotic prescription, drug interactions, and X-ray radiation are the most important considerations that may impact treatment planning and endodontic practice in pregnancy. The aim of this article is to notify and explain the latest concepts in the endodontic management of pregnant patients.

Physiology of pregnancy and oral local anesthesia considerations

Background

Safe and effective local anesthesia is a prerequisite for emergency oral surgeries and most dental treatments. Pregnancy is characterized by complex physiological changes, and increased sensitivity to pain. Pregnant women are particularly vulnerable to oral diseases, such as caries, gingivitis, pyogenic granuloma and third molar pericoronitis. Maternally administered drugs can affect the fetus through the placenta. Therefore, many physicians and patients are reluctant to provide or accept necessary local anesthesia, which leads to delays in the condition and adverse consequences. This review is intended to comprehensively discuss the instructions for local anesthesia in the oral treatment of pregnant patients.

Methodology

An in-depth search on Medline, Embase, and the Cochrane Library was performed to review articles concerned with maternal and fetal physiology, local anesthetic pharmacology, and their applications for oral treatment.

Results

Standard oral local anesthesia is safe throughout the pregnancy. At present, 2% lidocaine with 1:200,000 epinephrine is considered to be the anesthetic agent that best balances safety and efficacy for pregnant women. Maternal and fetal considerations must be taken into account to accommodate the physiological and pharmacological changes in the gestation period. Semi-supine position, blood pressure monitoring, and reassurance are suggested for high-risk mothers to reduce the risk of transient changes in blood pressure, hypoxemia, and hypoglycemia. For patients with underlying diseases, such as eclampsia, hypertension, hypotension, and gestational diabetes, the physicians should use epinephrine cautiously and control the dose of anesthetic. New local anesthesia formulations and equipment, which contribute to minimizing injection pain and relieving the anxiety, have and are being developed but remain understudied.

Conclusions

Understanding the physiological and pharmacological changes during pregnancy is essential to ensure the safety and efficiency of local anesthesia. Optimal outcomes for the mother and fetus hinge on a robust understanding of the physiologic alterations and the appropriate selection of anesthetic drugs and approaches.

The role of oral and prenatal healthcare providers in the promotion of oral health for pregnant women

BACKGROUND

Hormonal alterations and lowered immunity during pregnancy aggravated by poor oral hygiene increase the risk of pregnant women of developing oral diseases. We conducted this cross-sectional study to examine the role of oral and prenatal health providers in promoting dental care for pregnant women attending primary healthcare centers (PHCs) in Saudi Arabia.

METHODS

An online questionnaire was sent to a random sample of women who attended PHCs in Jeddah, during 2018-2019. From a total of 1350 women who responded to our questionnaire, 515 women reported having a dental visit before pregnancy. These women comprised our study sample. Bivariate analyses and multiple logistic regression models were conducted to examine associations between oral practices of dental and prenatal health providers (exposures) and women's utilization of dental care during pregnancy (outcome). Covariates included age, education (< 12 years of education, 12 years of education, and > 12 years of education), family income (≤ 5,000, 5,001-7,000, 7,001-10,000, and > 10,000 Saudi Riyals), health insurance (yes/no), nationality (Saudi Arabian/non-Saudi Arabian), and presence of dental problems, such as toothache, dental caries, gingival inflammation, and the need for dental extractions.

RESULTS

Only 30.0% of women were informed by a dentist during their dental visit before pregnancy about the importance of visiting a dentist during pregnancy. About 37.0% of women were asked about oral health, 34.4% were informed about the importance of dental care during pregnancy, and 33.2% had their mouths inspected by prenatal health providers. Women informed by dentists about the importance of dental visits during pregnancy were twice as likely (Odds ratio [OR]: 2.42, 95% confidence interval [CI]: 1.63-3.60) to visit a dentist during pregnancy. Women who were referred to dentists, had their mouth inspected, or were advised to visit a dentist during pregnancy by prenatal providers were 4.29 (95% CI: 2.67-6.88), 3.79 (95% CI: 2.47-5.82), and 3.37 (95% CI: 2.16-5.27) times as likely to visit a dentist during pregnancy.

CONCLUSION

The partaking of oral and prenatal healthcare providers in evidence-based oral health promotion practices, antenatal-dental collaboration, and closing the referral loop increase pregnant women's access to and utilization of preventive and treatment dental services.

Pain Relief Effects and Safety of Transitional Therapy in the Treatment of Posterior Teeth of Pregnant Women with Symptomatic Irreversible Pulpitis and Symptomatic Apical Periodontitis

Purpose

To assess the pain relief effects and safety of transitional therapy (TT) in the treatment of posterior teeth of pregnant women with symptomatic irreversible pulpitis and symptomatic apical periodontitis.

Methods

A prospective cohort clinical study was conducted in the Department of Stomatology at Shenzhen Maternity & Child Healthcare Hospital, China, from January 2017 to December 2019. We enrolled 62 pregnant women with acute dental pain caused by posterior teeth with symptomatic irreversible pulpitis or symptomatic apical periodontitis. Among the 62 participants, 34 received TT, and 28 chose nontreatment during pregnancy. We evaluated the pain relief with the verbal numerical rating scale (VNRS) scores of pain perception in the clinical study, as well as the anti-bacterial medicament filling conditions of canals of in vitro models. Moreover, we investigated the safety outcomes, such as gestational age, neonatal head circumstance, birth weight, and body length.

Results

The VNRS scores of the participants treated with TT were significantly lower than those of the nontreatment group 2 days after treatment (P<0.001). TT treated pregnant women experienced significantly more pain decreases in VNRS scores than their counterparts(P<0.05). The optimal anti-bacterial medicament filling conditions of canals of in vitro models by TT method were comparable with those of canals instrumented with traditional RCT method. Moreover, no significant differences of safety outcomes were observed between pregnant women of these two groups.

Conclusion

The transitional therapy is efficient in alleviating acute dental pain of posterior teeth of pregnant women with symptomatic irreversible pulpitis and symptomatic apical periodontitis, and maintaining painless chains throughout pregnancy with no adverse effects on neonatal birth outcomes.

Oral Health and Knowledge among Postpartum Women

Oral health behavior and risks during pregnancy and after birth affect the oral health of babies and toddlers. We examined the oral and gingival health and caries prevalence of 150 postpartum women shortly after giving birth and assessed their knowledge of oral hygiene using a questionnaire. We also compared the oral health knowledge of nulliparous and multiparous women. Although most participants (98.0%) understood the importance of maintaining oral hygiene in children, their overall knowledge of oral health was medium-low, regardless of the number of previous pregnancies. Only 4.6% of women received oral health advice from their obstetrician during their pregnancy. Most participants had a high gingival index score, which correlated with dental pain during pregnancy. In contrast, the number of decayed, missing and filled teeth was significantly lower in first-time mothers. There was a statistically significant positive correlation between women who regularly visit their dentist and those who regularly take their children to the dentist. Expecting mothers should be educated about their own oral health and that of their developing fetus and children. Raising awareness among obstetricians with regards to this topic may be an effective way to achieve this.

A Successful Dental Care Referral Program for Low-Income Pregnant Women in New York

Despite evidence-based guidelines that advocate for dental care during pregnancy, dental utilization among pregnant women remains low, especially among low-income and racial-ethnic minority women. We investigated self-reported dental care referral and self-reported dental care attendance among a group of 298 low-income, largely racial-ethnic minority pregnant women attending two suburban prenatal care clinics that had integrated dental care referrals into their prenatal care according to these guidelines. We administered a questionnaire that asked women: (1) whether they had been referred for care by their prenatal care provider; (2) whether they had been seen by a dentist during pregnancy. Among those women who were eligible for a dental care referral (those who reported having dental symptoms, and those not having a recent dental visit), we found that 73.0% reported that they had indeed been referred for dental care by their prenatal provider, while the remaining women reported either no referral (23.5%, n = 67) or were not sure whether they had been referred (3.5%, n = 10). Among those who reported a dental care referral, 67.3% (n = 140) reported that they saw a dentist during their pregnancy, while of those who reported no dental care referral only 35.1% (n = 27) reported a dental visit (Chi-Sq. = 24.1, df = 1, p < 0.001). Having received a dental referral was a significant predictor of reporting a dental visit during pregnancy, with women who received a referral being 4.6 times more likely to report a dental visit during pregnancy compared to those women who did not report a referral. These results demonstrate that vulnerable pregnant women referred for dental care by their prenatal provider will indeed seek and utilize dental care when offered. This dental referral program may serve as a model for improving the utilization of dental care among this population.

Dental Visits during Pregnancy: Pregnancy Risk Assessment Monitoring System Analysis 2012-2015

OBJECTIVES

This study aimed to update dental service utilization during pregnancy and to evaluate whether there are persistent disparities in dental care during pregnancy by race/ethnicity and Medicaid status.

METHODS

This retrospective secondary data analysis examined dental service utilization during and prior to pregnancy and met dental or oral health needs using the Pregnancy Risk Assessment Monitoring System (PRAMS) data sets on 75,876 women between 2012 and 2015.

RESULTS

Only about half of the women (51.7%) reported that they had at least 1 dental visit for cleaning during their most recent pregnancy. One of 5 women (19.7%) experienced dental problems during pregnancy, and 34.4% of these women did not visit dentists to address the problems. Non-Hispanic Black women had 14% lower odds of visiting dentists for cleaning during pregnancy compared to non-Hispanic White women (odds ratio [OR], 0.86; 95% CI confidence interval [CI], 0.80-0.92). There was no difference in dental visits prior to pregnancy between non-Hispanic Black and White women. Women enrolled in Medicaid showed significantly lower odds of visiting dentists for cleaning during pregnancy compared to women covered by private health insurance (OR, 0.55; 95% CI, 0.52-0.58).

CONCLUSION FOR PRACTICE

Oral health, as an integral part of primary care, needs to be included in the standard prenatal care through oral health education and timely dental care during pregnancy. With mounting evidence of persisting disparities in dental service utilization during pregnancy, both public and private prenatal programs and policies should address specific barriers in accessing and using dental care during pregnancy, especially for women from socially disadvantaged backgrounds.

KNOWLEDGE TRANSFER STATEMENT

The current study updated the previous findings with more recent multiyear PRAMS data (2012-2015) and found the Black-White disparity and disparity among Medicaid-enrolled women in visiting dentists during pregnancy persist. The results of this study can be used by policymakers and practitioners to integrate oral health into prenatal care for pregnant women from marginalized backgrounds to achieve oral health parity.

What Factors Influence Dental Faculty's Willingness to Treat Pregnant Women?

BACKGROUND

Despite evidence-based guidelines advocating for the provision of oral health care throughout pregnancy, dentists remain hesitant to provide dental treatment for pregnant women. However, little is known about attitudes toward treating pregnant women among dental school faculty, who may transmit their attitudes and treatment preferences to their students.

METHODS

We collected cross-sectional survey data at the New York University College of Dentistry, which produces 10% of all US dentists and is the largest US dental school, to understand faculty attitudes and knowledge regarding providing dental treatment to pregnant women. This study was part of an educational effort to improve dental care access by pregnant women and to examine what factors influence willingness to treat pregnant patients among dental faculty members.

RESULTS

We found that concerns about professional liability outweighed inadequate knowledge regarding treatment of pregnant patients in determining dental faculty's willingness to treat pregnant women.

CONCLUSIONS

Educational interventions delivered to dental faculty regarding current dental treatment guidelines for pregnant women may not be sufficient to increase faculty's provision of dental care to women during pregnancy. Future work to design effective interventions to increase dental treatment of pregnant women among dental faculty should address liability concerns.

KNOWLEDGE TRANSFER STATEMENT

Interventions addressing dental clinician and faculty knowledge about dental treatment for pregnant women may be insufficient to increase dental treatment among pregnant women. Instead, policy makers should consider designing, implementing, and evaluating interventions addressing malpractice and liability concerns.

The Impact of Dental Insurance and Medical Insurance on Dental Care Utilization During Pregnancy

OBJECTIVE

To measure the association between dental and medical insurance with the receipt of dental cleaning during pregnancy.

METHODS

We analyzed Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2012 to 2015 on 145,051 women with a recent live birth from 36 states. We used adjusted prevalence ratios [aPR] from multivariable regression to examine the association of dental and medical insurance with receipt of dental cleaning during pregnancy, controlling for selected covariates that influence dental care utilization.

RESULTS

Seventy-seven percent (77%) of all women reported having dental insurance during pregnancy. Receipt of dental cleaning before pregnancy was strongly associated with dental cleaning during pregnancy. Among women without pre-pregnancy dental cleaning who had dental insurance, those with Medicaid medical insurance had a significantly higher prevalence of dental cleaning during pregnancy [aPR = 1.42, 95% CI (1.32 - 1.52)], compared to those private medical insurance. Among women without pre-pregnancy dental cleaning, those without dental insurance but with Medicaid medical insurance were about 70% less likely to have dental cleaning during pregnancy compared to those with dental and private medical insurance.

CONCLUSIONS FOR PRACTICE

With or without dental insurance, pre-pregnancy dental cleaning was strongly associated with dental cleaning during pregnancy. Dental insurance was an important determinant of dental utilization. Medical insurance had an independent and positive effect. This effect varied by private versus Medicaid medical insurance. Programs which provide women with dental insurance both before and during pregnancy could improve the oral health of maternal and infant populations.

Pregnancy and Dentistry: A Literature Review on Risk Management during Dental Surgical Procedures

Background: Pregnancy is a unique moment in a woman’s life, accompanied with several physiologic changes that have an impact on oral health. Aim of the study: The purpose of the present study was to conduct a critical review of published literature regarding pregnancy and dentistry, the most frequent oral diseases that are encountered during pregnancy, their correlation to adverse pregnancy events, and safe dental treatments that can be performed during pregnancy. Methods: A Medline/COCHRANE search was carried using specific keywords and MeSH terms, combined with the boolean operators “OR” and “AND”. Results: The search led to 146 publications including guidelines, meta-analyses, systematic and non-systematic reviews, published between 2000 and 2021. Discussion and conclusions: Due to the increased inflammatory and immune body response that characterizes pregnancy, periodontal conditions are often aggravated during pregnancy and periodontal disease encountered frequently in pregnant patients. There are conflicting study results in the literature regarding the association between periodontitis and adverse pregnancy outcomes. Periodontal treatment did not show a significant reduction in the adverse outcomes. Many dentists, often due to lack of information, are reluctant to provide dental treatment to pregnant women. However, preventive and restorative dental treatment is safe during pregnancy. Diagnostic radiographs may be performed after the first trimester if absolutely necessary. Analgesics (such as paracetamol) and anesthetics (such as lidocaine) are also considered safe. In case of infection, antibacterial drugs such as amoxicillin, ampicillin, and some cephalosporines and macrolides can also be prescribed. Organogenesis takes place in the first trimester, the time during which the fetus is susceptible to severe malformations (teratogenesis). The ideal time to perform dental treatment is the second trimester (week 17 to 28). However, acute pain or infections make the intervention of the dentist absolutely necessary and emergency treatment can be performed during the whole pregnancy period.

Oral microbiome and pregnancy: A bidirectional relationship

The oral cavity contains the second most complex microbial population within the human body, with more than 700 bacterial organisms. Recent advances in Next Generation Sequencing technology have unraveled the complexities of the oral microbiome and provided valuable insights into its role in health and disease. The human oral microbiome varies dramatically during the different stages of life, including pregnancy. The total viable microbial counts in pregnant women are known to be higher compared to non-pregnant women, especially in the first trimester of pregnancy. A balanced oral microbiome is vital for a healthy pregnancy, as perturbations in the oral microbiome composition can contribute to pregnancy complications. On the other hand, physiological changes and differences in hormonal levels during pregnancy, increase susceptibility to various oral diseases such as gingivitis and periodontitis. A growing body of evidence supports the link between the composition of the oral microbiome and adverse pregnancy outcomes such as preterm birth, preeclampsia, low birth weight among others. This review aims to summarize the dynamics of oral microbiome during pregnancy and to discuss the relationship between a dysbiotic oral microbiome and pregnancy complications.

Managing migraine in pregnancy and breastfeeding

The disproportionate prevalence of migraine among women in their reproductive years underscores the clinical significance of migraine during pregnancy. This paper discusses how migraine evolves during pregnancy, secondary headache disorders presenting in pregnancy and puerperium, and acute and preventive options for migraine management during pregnancy and lactation. Migraine is influenced by rising estrogen levels during pregnancy and their sharp decline in puerperium. Migraine, and migraine aura, can present for the first time during pregnancy and puerperium. There is also a higher risk for the development of preeclampsia and cerebrovascular headache during these periods. New or refractory headache, hypertension, and abnormal neurological signs are important "red flags" to consider. This paper reviews the diagnostic utility of neuroimaging studies and the risks of each during pregnancy. Untreated migraine can itself lead to preterm delivery, preeclampsia, and low birth weight infants. Behavioral interventions and lifestyle modifications are the cornerstone for migraine treatment during pregnancy. In addition, one should consider the risks and efficacy of each treatment during pregnancy on an individual basis. The protective nature of breastfeeding for migraine is debated, but there is no evidence to suggest breastfeeding worsens migraine. Acute and preventive migraine treatment options are available for nursing mothers. Neuromodulation and neurostimulation devices are additional options for treatment during pregnancy and lactation, while the safety of using calcitonin gene-related peptide receptor antagonists during these times remains to be determined.

Periodontal disease and adverse pregnancy outcomes

Periodontal diseases are considered not only to affect tooth-supporting tissues but also to have a cause-and-effect relationship with various systemic diseases and conditions, such as adverse pregnancy outcomes. Mechanistic studies provide strong evidence that periodontal pathogens can translocate from infected periodontium to the feto-placental unit and initiate a metastatic infection. However, the extent and mechanisms by which metastatic inflammation and injury contribute to adverse pregnancy outcomes still remain unclear. The presence of oral bacteria in the placenta of women with term gestation further complicates our understanding of the biology behind the role of periodontal pathogens in pregnancy outcomes. Epidemiological studies demonstrate many methodological inconsistencies and flaws that render comparisons difficult and conclusions insecure. Therefore, despite the fact that a number of prospective studies show a positive association between periodontal diseases and various adverse pregnancy outcomes, the evidence behind it is still weak. Future well-designed explanatory studies are necessary to verify this relationship and, if present, determine its magnitude. The majority of high-quality randomized controlled trials reveal that nonsurgical periodontal therapy during the second trimester of gestation does not improve pregnancy outcomes. From a biological standpoint, this can be partially explained by the fact that therapy rendered at the fourth to sixth months of pregnancy is too late to prevent placental colonization by periodontal pathogens and consequently incapable of affecting pathogen-induced injury at the feto-placental unit. Thus, interventions during the preconception period may be more meaningful. With the increase in our understanding on the potential association between periodontal disease and adverse pregnancy outcomes, it is clear that dental practitioners should provide periodontal treatment to pregnant women that is safe for both the mother and the unborn child. Although there is not enough evidence that the anti-infective therapy alters pregnancy outcomes, it improves health-promoting behavior and periodontal condition, which in turn advance general health and risk factor control.

Utilization of dental services among low and middle income pregnant, post-partum and six-month post-partum women

Background

This study aims to explore the difference in the utilization pattern of dental services among pregnant, post-partum and six-month post-partum women.

Methods

This cross-sectional questionnaire survey was performed at two maternity and child care hospitals in India that primarily cater to middle and low income communities. Data were collected from 3 groups: 1) pregnant women in their first trimester; 2) post-partum women (< 48 h after delivery); and 3) six-month post-partum women. The primary outcome of interest was dental service utilization during pregnancy. Self-perceived oral health (SPOH) was calculated based on the four global dimensions- knowledge, function, quality of life and social. Multiple logistic regression analysis was carried out to assess the effect of each independent variable after adjustment for the effect of all other variables in the model.

Results

Responses of 450 (150 pregnant, 150 post-partum and 150 six-month post-partum) women were analyzed (response rate = 72%). Significant differences in the dental attendance pattern was observed between the study groups (p < 0.01). Dental attendance among pregnant and six-month post-partum women were 60 and 75%, respectively, however, only about 15% of the post-partum women reported to have sought dental care within the 6 months prior to the study. Post-partum women had the highest SPOH scores, indicating poor self-perceived oral health, followed by pregnant and then six-month post-partum women, which was statistically significant (p < 0.05). A significantly higher percentage of post-partum women reported to have poor oral and general health, as compared to both, pregnant and six-month post-partum women (p < 0.01). Higher percentage of women reporting ‘good’ oral and general health had sought dental care compared with others (p < 0.01). After adjusting for all the other variables in the model, women with lower levels of education (OR^a = 1.42; 95% CI: 1.01–2.00), women with poor self-perceived oral health (OR^a = 1.08; 95% CI: 1.02–1.14) and post-partum women (OR^a = 0.15; 95% CI: 0.09–0.24) were found to be less likely to seek regular dental care.

Conclusion

Pattern of dental service utilization among women in this population varied according to their pregnancy status, level of education and self-perceived oral health.

Effectiveness of an integrated perinatal oral health assessment and promotion program on the knowledge in Indian pregnant women

BACKGROUND

Oral health during pregnancy plays a crucial role in the overall health and well-being of pregnant women. Evidence shows that most young children acquire cariogenic organisms from their mothers. Poor maternal knowledge about oral diseases combined with inappropriate feeding can lead to severe caries among young children. The aim of study was to assess the oral health status of pregnant women and to evaluate the gain in their knowledge after educational session in an antenatal setting.

MATERIALS AND METHODS

It is a pre- and post-intervention study carried out on the pregnant women (n = 198) attending an antenatal clinic in a tertiary care hospital. A specially designed semi-structured 14-point questionnaire was used to assess the pre- and post-knowledge and attitude to the oral health. Each participant was educated for self and infant oral care with the help of a specially prepared colored printed booklet. Kruskal-Wallis test was used to explore the associations between the age, education and socioeconomic class and knowledge; Wilcoxon signed-rank test was used to compare pre- and post-knowledge score.

RESULTS

Median preoral health knowledge-attitude score was found to be 4 (0-8) and was found to be associated with the level of education (P = 0.014) and socioeconomic class (0.019). There was a significant improvement in the median postknowledge score to 7 (2-10) (P < 0.001) following oral health educational session in all categories.

CONCLUSIONS

An integrated preventive oral health checkup and educational program to pregnant women can benefit the dental health of the women and children. Prenatal care workers can be involved to disseminate the oral health awareness to pregnant women during antenatal visits.

Number of Pregnant Women at Four Dental Clinics and the Care They Received: A Dental Quality eMeasure Evaluation

Process-of-care quality measure research can be used to identify gaps in the delivery of dental services to pregnant patients. The aim of this study was to evaluate the types of dental services that pregnant patients received in four dental clinics over five years as documented in the electronic health record (EHR). To accomplish this objective, the authors modified and validated a previously published claims-based dental quality measure for EHR use. After the electronic dental quality measure specifications were defined, the number of pregnant patients was calculated at three academic dental institutions and one large accountable care organization, and the types of dental care services they received over a five-year period (2013-17) were determined. Calibrated reviewers at each institution independently reviewed a sub-sample of patient charts to validate the information obtained from EHR queries, and the concordance between manual chart reviews and EHR query reports was analyzed. Of the 335,078 women aged 15-44 years who received care at the four clinics for the five reporting years, 3.9% (n=13,026) were pregnant. Among these pregnant patients, 48.9% (n=6,366) received a periodic dental examination; 30.0% (n=3,909) received a comprehensive dental exam; and 21.5% (n=2,799) received additional dental services, irrespective of comprehensive or periodic oral evaluations. Overall, the mean proportion of pregnant patients seeking care in these academic dental and group practice clinics was low, but 78.9% of them received either a periodic or comprehensive oral evaluation. Given the importance of oral health care during pregnancy, these findings suggest a need for curriculum development to incorporate prenatal oral health education in the training of dental students.

Protect Tiny Teeth Toolkit: An Oral Health Communications Resource for Providers of Pregnant Women and New Mothers

Oral health is important to general health, yet is often overlooked. During pregnancy, women may be more prone to periodontal (gum) disease and cavities, and research has shown an association between these conditions and adverse pregnancy outcomes. Additionally, a mother's oral health status is a strong predictor of her children's oral health status. Primary care providers often have an opportunity to influence their patients' attitudes and behaviors regarding the importance of oral health during pregnancy. Through a cooperative agreement with the Centers for Disease Control and Prevention, the American Academy of Pediatrics worked to create Protect Tiny Teeth, an oral health communications resource that aims to facilitate conversations between pregnant women and their health care providers, as well as educate women and families about the importance of oral health.

Knowledge of Pregnant Women about Pregnancy Gingivitis and Children Oral Health

Objective A cross-sectional questionnaire-based study was carried out among 251 pregnant women to assess their level of knowledge and perception regarding pregnancy gingivitis and the oral health of new born children.

Materials and Methods A self-administered validated questionnaire was distributed among pregnant women visiting the Child and Maternity Hospital, Ministry of Health, Aseer, Saudi Arabia. The questionnaire included the questions related to their knowledge/awareness about cause, treatment, preventive measures, and the adverse effects of gingivitis on oral health of a woman.

Statistical Analysis The data was entered into Microsoft excel sheet and put to statistical analysis using SPSS (version 17). Descriptive analysis and also chi-squared test was used for comparison.

Results Majority of pregnant women were found unaware about developing of pregnancy gingivitis as well as the cause, effects, treatment, and preventive measures for the same. Most of the subjects agreed that it was essentially required to have oral health education before their pregnancy term would start.

Conclusion Most of the pregnant women said that they were unaware about pregnancy gingivitis, though few reported of being aware about it. It is inferred that the collaborative efforts between general dentists, pediatric dentists, public health dentists, and medical professionals are needed to raise awareness among pregnant women regarding timely dental care to avoid the adverse pregnancy related outcomes due to gingivitis and periodontitis.

Calcium and vitamin D supplementation and/or periodontal therapy in the treatment of periodontitis among Brazilian pregnant women: protocol of a feasibility randomised controlled trial (the IMPROVE trial)

Background

Periodontitis is a common oral inflammation, which is a risk factor for adverse pregnancy outcomes. Intakes of vitamin D and calcium are inversely associated with occurrence and progression of periodontitis. This study aims to assess the feasibility of a multi-component intervention, including provision of milk powder supplemented with calcium and vitamin D and periodontal therapy (PT), for improving maternal periodontal health and metabolic and inflammatory profiles of low-income Brazilian pregnant women with periodontitis.

Methods

The IMPROVE trial is a feasibility randomised controlled trial (RCT) with a 2 × 2 factorial design with a parallel process evaluation. Pregnant women with periodontitis, aged 18–40 years and with < 20 gestational weeks (n = 120) were recruited and randomly allocated into four groups: (1) fortified sachet (vitamin D and calcium) and powdered milk plus PT during pregnancy, (2) placebo sachet and powdered milk plus PT during pregnancy, (3) fortified sachet (vitamin D and calcium) and powdered milk plus PT after delivery and (4) placebo sachet and powdered milk plus PT after delivery. Dentists and participants are blinded to fortification. Acceptability of study design, recruitment strategy, random allocation, data collection procedures, recruitment rate, adherence and attrition rate will be evaluated. Data on serum levels of vitamin D, calcium and inflammatory biomarkers; clinical periodontal measurements; anthropometric measurements; and socio-demographic questionnaires are collected at baseline, third trimester and 6–8 weeks postpartum. Qualitative data are collected using focus group, for analysis of favourable factors and barriers related to study adherence.

Discussion

Oral health and mineral/vitamin supplementation are much overlooked in the public prenatal assistance in Brazil and of scarcity of clinical trials addressing these issues in low and middle-income countries,. To fill this gap the present study was designed to assess the feasibility of a RCT on acceptability of a multi-component intervention combining conventional periodontal treatment and consumption of milk fortified with calcium-vitamin D for improving periodontal conditions and maternal metabolic and inflammation status, among Brazilian low-income pregnant women with periodontitis. Thus, we hope that this relatively low-cost and safe multicomponent intervention can help reduce inflammation, improve maternal periodontal health and metabolic profile and consequently prevent negative gestational outcomes.

Oral Health Status and Treatment Needs of Pregnant Women Attending Antenatal Clinics in KwaZulu-Natal, South Africa

During pregnancy, the oral cavity is characterised by an acidic environment and an inflammatory response brought about by vomiting and changes in hormonal levels, respectively, thereby increasing the mother's risk of developing caries. Although evidence exists to support an association between pregnancy-associated periodontal disease and adverse pregnancy outcomes, there is a paucity of studies which focus on the caries prevalence and other oral manifestations of pregnant women. The aim of this study was to assess the oral health status and treatment needs of pregnant women attending antenatal clinics in KwaZulu-Natal, South Africa. Randomly selected mothers (n=443) attending a maternal obstetrics unit participated in the study. A questionnaire elicited demographic information about the participants, while the measurement of decayed, missing, and filled indices (DMFT) determined their caries status. Oral lesions were noted if present. Descriptive statistics for independent variables described frequencies in the various categories of race, location, pregnancy stage, etc., with the association between 2 independent variables tested by chi-square. Dependent variables such as DMFT were expressed as means and standard deviations, and ANOVA was used to examine whether independent variables significantly influenced the DMFT. The mean DMFT was 7.18 (±4.22) with significant correlations observed between DMFT, D, M, and age. F scores differed significantly between races, location, and educational levels and showed a significant correlation with pregnancy stage. Pregnancy epulis was diagnosed in 38 (8.5%), oral lesions in 65 (14.7%), and tooth mobility in 26 (5.9%) mothers. Early oral health screening during pregnancy can ensure the overall well-being of both the mother and the foetus.

Polymer-based dental filling materials placed during pregnancy and risk to the foetus

Background

Tooth-coloured polymer-based dental filling materials are currently the first choice for dental restorative treatment in many countries. However, there are some concerns about their safety. It has been shown that substances known as endocrine disrupters, which might pass through the placental barrier, are released from these materials within the first hours after curing. Thus, the placement of polymer-based dental fillings in pregnant women may put the vulnerable foetus at risk. Large epidemiological studies exploring the risk of having polymer-based dental materials placed during pregnancy are lacking. The aim of this study was to investigate the association between the placement of polymer-based dental fillings during pregnancy and adverse birth outcomes.

Methods

This study is based on data from the large Norwegian Mother and Child Cohort Study (MoBa). The information about dental treatment during pregnancy was obtained from questionnaires sent to the participating women during weeks 17 and 30 of pregnancy. Reported placement of “white fillings” was used as exposure marker for having received polymer-based dental filling materials. Only singleton births were included in the present study. Data were linked to the Medical Birth Registry of Norway. Logistic regression models that included the mother’s age, level of education, body mass index, parity, and smoking and alcohol consumption during pregnancy were used to estimate the odds ratio (OR) and 95% confidence interval (CI). Different adverse birth outcomes were of interest in the present study.

Results

Valid data were available from 90,886 pregnancies. Dentist consultation during pregnancy was reported by 33,727 women, 10,972 of whom had white fillings placed. The adjusted logistic regression models showed no statistically significant association between having white dental fillings placed during pregnancy and stillbirth, malformations, preterm births, and low or high birth weight.

Conclusions

In this study, women who reported white fillings placed during pregnancy had no increased risk for adverse birth outcomes compared with women who did not consult a dentist during pregnancy. Thus, our findings do not support the hypothesis of an association between placement of polymer-based fillings during pregnancy and adverse birth outcomes.

Oral Health Interventions During Pregnancy

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.

IL-6 and TNF-α salivary levels according to the periodontal status in Portuguese pregnant women

Background

Periodontitis is associated with increased concentration of inflammatory markers and saliva has been proposed as a non-invasive diagnostic fluid in oral and systemic diseases. The levels of salivary biomarkers, such as cytokines, could potentially be used to distinguish periodontal healthy individuals from subjects with periodontal disease. The purpose of this study was to characterize the salivary levels of two inflammatory biomarkers associated with periodontitis, interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-α), in order to assess whether these cytokines salivary levels could potentially be used to complement periodontitis pregnant women diagnose.

Methods

Forty-four pregnant women were distributed into three groups, according to their periodontal status: healthy, mild/moderate periodontitis and severe periodontitis. Unstimulated saliva was collected and analysis of TNF-α and IL-6 salivary levels were performed with Immulite^®.

Results

Women with periodontitis exhibited significantly higher levels (p = 0.001) of salivary IL-6 and TNF-α compared with the healthy group: 25.1 (±11.2) pg/mL vs. 16.3 (±5.0) pg/mL and 29.7 (±17.2) pg/mL vs. 16.2 (±7.6) pg/mL, approximately 1.5 and 1.8 times more, respectively. Additionally, cytokines were significantly increased (p < 0.05) in severe periodontitis compared to periodontal healthy pregnant women.

Conclusions

These results revealed that IL-6 and TNF-α salivary biomarkers provide high discriminatory capacity for distinguishing periodontal disease from periodontal health in pregnant women.

Pregnant Women's Infant Oral Health Knowledge and Beliefs: Influence of Having Given Birth and of Having a Child in the Home

Introduction Prenatal oral health interventions can positively impact maternal and child oral health, yet limited information exists concerning how to best educate pregnant women about infant oral health. Our objective was to examine the influence of having given birth on pregnant women's infant oral health knowledge and beliefs. Methods We conducted a secondary analysis of data collected from a cross-sectional survey of pregnant women ≥18 years old attending UNC's Ultrasound Clinic. Four binomial items were categorized as infant knowledge (IK) and five rated on a Likert scale (1-5) as infant belief (IB). Overall IK and IB scores were calculated, averaging the items within each construct. Respondents were categorized into two groups: multiparous (N = 268), women having at least one previous live birth and a child between 2 and 6 years old, or nulliparous (N = 186), women with no previous live births or a child between 2 and 6 years old. Regression models for IK and IB were conducted using SAS 9.2 with maternal demographic characteristics, dental utilization, and birth history as explanatory variables (p ≤ 0.05). Results IK was affected by race (p = 0.04), mother's oral health self-rating (p = 0.0002), and birth history (p < 0.0001). On average, IK was 0.12 units higher in subjects with a history of giving birth, adjusting for explanatory variables. IB was influenced by maternal oral health beliefs (p = 0.002) and history of access to dental care (p = 0.0002). IB did not differ based on birth history (p = 0.17). Discussion The influence of birth history on pregnant women's infant oral health knowledge and beliefs can be considered in future intervention designs to maximize available resources.

Use of local anesthetics for dental treatment during pregnancy; safety for parturient

Pregnancy induces significant anatomical and physiological changes in the mother. Many pregnant women need dental treatment due to poor oral hygiene related to pregnancy. However, most dentists are reluctant to provide, and most pregnant women are reluctant to receive, dental treatment during pregnancy. Theoretically, maternally administered drugs are transferred to the fetus. Depending on the types of drugs and the stage of pregnancy, the effects of drugs on the mother, as well as the fetus, may vary. Local anesthetics are the most widely used in dental treatment. It is, therefore, important to understand the potential effects of local anesthetics during pregnancy. In this review, we will focus on the maternal and fetal effects of local anesthetics widely used in dental treatment with consideration of the use of local anesthetics during pregnancy.

Treating periodontal disease for preventing adverse birth outcomes in pregnant women

BACKGROUND

Periodontal disease has been linked with a number of conditions, such as cardiovascular disease, stroke, diabetes and adverse pregnancy outcomes, all likely through systemic inflammatory pathways. It is common in women of reproductive age and gum conditions tend to worsen during pregnancy. Some evidence from observational studies suggests that periodontal intervention may reduce adverse pregnancy outcomes. There is need for a comprehensive Cochrane review of randomised trials to assess the effect of periodontal treatment on perinatal and maternal health.

OBJECTIVES

To assess the effects of treating periodontal disease in pregnant women in order to prevent or reduce perinatal and maternal morbidity and mortality.

SEARCH METHODS

Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 6 October 2016), Cochrane Pregnancy and Childbirth's Trials Register (to 7 October 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 9) in the Cochrane Library, MEDLINE Ovid (1946 to 6 October 2016), Embase Ovid (1980 to 6 October 2016), and LILACS BIREME Virtual Health Library (Latin American and Caribbean Health Science Information database; 1982 to 6 October 2016). ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials on 6 October 2016. We placed no restrictions on the language or date of publication when searching the electronic databases.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) investigating the effects of periodontal treatment in preventing or reducing perinatal and maternal morbidity and mortality. We excluded studies where obstetric outcomes were not reported.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles and abstracts and extracted data using a prepiloted data extraction form. Missing data were obtained by contacting authors and risk of bias was assessed using Cochrane's 'Risk of bias' tool. Where appropriate, results of comparable trials were pooled and expressed as risk ratios (RR) or mean differences (MD) with 95% confidence intervals (CI) . The random-effects model was used for pooling except where there was an insufficient number of studies. We assessed the quality of the evidence using GRADE.

MAIN RESULTS

There were 15 RCTs (n = 7161 participants) meeting our inclusion criteria. All the included studies were at high risk of bias mostly due to lack of blinding and imbalance in baseline characteristics of participants. The studies recruited pregnant women from prenatal care facilities who had periodontitis (14 studies) or gingivitis (1 study).The two main comparisons were: periodontal treatment versus no treatment during pregnancy and periodontal treatment versus alternative periodontal treatment. The head-to-head comparison between periodontal treatments assessed a more intensive treatment versus a less intensive one.Eleven studies compared periodontal treatment with no treatment during pregnancy. The meta-analysis shows no clear difference in preterm birth < 37 weeks (RR 0.87, 95% CI 0.70 to 1.10; 5671 participants; 11 studies; low-quality evidence) between periodontal treatment and no treatment. There is low-quality evidence that periodontal treatment may reduce low birth weight < 2500 g (9.70% with periodontal treatment versus 12.60% without treatment; RR 0.67, 95% CI 0.48 to 0.95; 3470 participants; 7 studies).It is unclear whether periodontal treatment leads to a difference in preterm birth < 35 weeks (RR 1.19, 95% CI 0.81 to 1.76; 2557 participants; 2 studies; ) and < 32 weeks (RR 1.35, 95% CI 0.78 to 2.32; 2755 participants; 3 studies), low birth weight < 1500 g (RR 0.80, 95% CI 0.38 to 1.70; 2550 participants; 2 studies), perinatal mortality (including fetal and neonatal deaths up to the first 28 days after birth) (RR 0.85, 95% CI 0.51 to 1.43; 5320 participants; 7 studies; very low-quality evidence), and pre-eclampsia (RR 1.10, 95% CI 0.74 to 1.62; 2946 participants; 3 studies; very low-quality evidence). There is no evidence of a difference in small for gestational age (RR 0.97, 95% CI 0.81 to 1.16; 3610 participants; 3 studies; low-quality evidence) when periodontal treatment is compared with no treatment.Four studies compared periodontal treatment with alternative periodontal treatment. Data pooling was not possible due to clinical heterogeneity. The outcomes reported were preterm birth < 37 weeks, preterm birth < 35 weeks, birth weight < 2500 g, birth weight < 1500 g and perinatal mortality (very low-quality evidence). It is unclear whether there is a difference in < 37 weeks, preterm birth < 35 weeks, birth weight < 2500 g, birth weight < 1500 g and perinatal mortality when different periodontal treatments are compared because the quality of evidence is very low.Maternal mortality and adverse effects of the intervention did not occur in any of the studies that reported on either of the outcomes.

AUTHORS' CONCLUSIONS

It is not clear if periodontal treatment during pregnancy has an impact on preterm birth (low-quality evidence). There is low-quality evidence that periodontal treatment may reduce low birth weight (< 2500 g), however, our confidence in the effect estimate is limited. There is insufficient evidence to determine which periodontal treatment is better in preventing adverse obstetric outcomes. Future research should aim to report periodontal outcomes alongside obstetric outcomes.

Dental caries and periodontal disease among U.S. pregnant women and nonpregnant women of reproductive age, National Health and Nutrition Examination Survey, 1999-2004

OBJECTIVES

This study assessed and compared the prevalence and severity of dental caries and the prevalence of periodontal disease among pregnant and nonpregnant women of reproductive age (15-44 years) using data from the National Health and Nutrition Examination Survey, NHANES (1999-2004).

METHODS

Estimates were derived from a sample of 897 pregnant women and 3,971 nonpregnant women. Chi-square and two-sample t-tests were used to assess differences between groups stratified by age, race/ethnicity, education, and poverty. Bonferroni method was applied to adjust for multiple comparisons.

RESULTS

In general, there were no statistically significant differences in the prevalence estimates of dental caries and periodontal disease between pregnant women and nonpregnant women. However, results showed significant differences when stratified by sociodemographic characteristics. For example, the prevalence of untreated dental caries among women aged 15-24 years was significantly higher in pregnant women than in nonpregnant women (41 percent versus 24 percent, P = 0.001). Regardless of their pregnancy status, racial/ethnic minorities or women with less education or lower family income had higher prevalence of untreated dental caries, severity of dental caries, and periodontal disease compared to the respective reference groups of non-Hispanic whites or women with more education or higher family income.

CONCLUSION

Results of this study show few clinical differences in dental caries and periodontal disease between pregnant and nonpregnant women but persistent disparities by sociodemographic characteristics. In order to reduce oral health disparities in the United States, it is important to improve access to oral health care particularly among vulnerable groups. Integrating oral health into the overall health care could benefit and improve women's oral health outcomes.

Knowledge and Attitude of Medical Nurses toward Oral Health and Oral Health Care of Pregnant Women

BACKGROUND

This study assessed the knowledge and attitudes of medical nurses regarding oral health and oral health care of pregnant women.

METHODS

This cross sectional study of 133 nurses in the district of Tumpat, Kelantan (Malaysia) used self-administered questionnaires.

RESULTS

Most nurses knew that dental plaque is associated with periodontal disease (97.7%). However, most nurses erroneously believed that tooth decay (86.5%) and excessive sugar consumption (87.2%) led to periodontal disease. About half of the nurses knew about the relationship between periodontal disease of pregnant women and low birth weight (43.6%) and preterm birth (48.9%). Many nurses had the misconception that the developing foetus draws calcium from the mothers' teeth (78.2%). Most nurses had good attitudes toward improving their oral health knowledge (97.0%) and agreed they should help to deliver oral health education to pregnant women (94.0%). Age, length of service as a nurse, and length of service in antenatal care had no effect on the scores for the nurses' knowledge and attitude regarding oral health and oral health care of pregnant women.

CONCLUSION

Medical nurses had limited knowledge about oral health of pregnant women and had some misunderstandings about oral health, although they had good attitudes. Age, length of service as a nurse, and length service in antenatal care had no effect on the knowledge and attitude scores of the nurses.

The evaluation of an oral health education program for midwives in Australia

BACKGROUND

Antenatal care providers are now recommended to promote oral health during pregnancy and provide dental referrals. However, midwives in Australia are not trained to undertake this role. To address this shortcoming, an online evidence based midwifery initiated oral health (MIOH) education program was systematically developed as a professional development activity.

AIM

This study aimed to evaluate the effectiveness of the program in improving the oral health knowledge of midwives and assess their confidence to promote maternal oral health post training.

METHODS

The program was evaluated using a pre-post test design involving 50 midwives purposively recruited from two states in Australia. The pre-post questionnaire contained 24 knowledge items previously pilot tested as well as items exploring confidence in promoting oral health and perceptions of the program.

FINDINGS

The results showed a significant improvement in the oral health knowledge (↑21.5%, p<0.001) of midwives after completion of the program. The greatest improvement in knowledge occurred in key areas vital in promoting maternal oral health namely the high prevalence of dental problems and its impact on birth and infant outcomes. The majority also reported being confident in introducing oral health into antenatal care (82%) and referring women to dental services (77.6%) after undertaking the education program.

CONCLUSION

The MIOH education program is a useful resource to equip midwives with the necessary knowledge and skills to promote oral health during pregnancy. The program is accessible and acceptable to midwives and can potentially be transferable to other antenatal care providers.

Periodontal treatment outcomes during pregnancy and postpartum

OBJECTIVE

This study was conducted to compare periodontal therapy outcomes during pregnancy and after delivery.

MATERIALS AND METHODS

One hundred nine pregnant women up to the 20th gestational week (GW) were randomized into two groups: the test group (comprehensive periodontal therapy during pregnancy) and the control group (comprehensive periodontal therapy after delivery). Periodontal examinations comprised plaque index (PI), gingival index (GI), periodontal probing depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and gingival crevicular fluid (GCF) volume. After baseline examination, women in the test group received periodontal treatment up to the 24th GW. The final examination was performed at the 26th to the 28th GW. Women in the control group were treated 30 days after delivery and reexamined 30 days after treatment.

RESULTS

Periodontal therapy significantly reduced periodontal inflammation in both groups. The mean percentage of sites with BOP was reduced from 49.14 % (±22.49) to 11.10 % (±7.84) and from 45.71 % (±17.86) to 8.07 % (±5.21) in the test and control groups, respectively (p = 0.95). No statistically significant differences were observed between groups concerning PI, GI, PPD, CAL, and GCF. The reduction in mean percentage of sites with BOP stratified for initial PPD ≥4 mm was higher in the control group (p < 0.01), but no differences were seen regarding GCF in these sites.

CONCLUSIONS

Hormonal changes during pregnancy do not interfere in treatment outcomes in women with widespread gingival inflammation and limited periodontal destruction. The role of these hormonal changes in pregnant women with different disease patterns remains uncertain.

CLINICAL RELEVANCE

Periodontal health can be reestablished irrespective of the hormonal challenge that takes place during pregnancy.

Oral health conditions and dental visits among pregnant and nonpregnant women of childbearing age in the United States, National Health and Nutrition Examination Survey, 1999-2004

INTRODUCTION

Oral diseases can be prevented or improved with regular dental visits. Our objective was to assess and compare national estimates on self-reported oral health conditions and dental visits among pregnant women and nonpregnant women of childbearing age by using data from the National Health and Nutrition Examination Survey (NHANES).

METHODS

We analyzed self-reported oral health information on 897 pregnant women and 3,971 nonpregnant women of childbearing age (15-44 years) from NHANES 1999-2004. We used χ(2) and 2-sample t tests to assess statistical differences between groups stratified by age, race/ethnicity, poverty, and education. We applied the Bonferroni adjustment for multiple comparisons.

RESULTS

Our data show significant differences in self-reported oral health conditions and dental visits among women, regardless of pregnancy status, when stratified by selected sociodemographic characteristics. Significant differences were also found in self-reported oral health conditions and dental visits between pregnant and nonpregnant women, especially among young women, women from minority race/ethnicity groups, and women with less than high school education.

CONCLUSION

We found disparities in self-reported oral health conditions and use of dental services among women regardless of pregnancy status. Results highlight the need to improve dental service use among US women of childbearing age, especially young pregnant women, those who are non-Hispanic black or Mexican American, and those with low family income or low education level. Prenatal visits could be used as an opportunity to encourage pregnant women to seek preventive dental care during pregnancy.

Bi-directional relationship between pregnancy and periodontal disease

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.

Association of a common genetic factor, PTGER3, with outcome of periodontal therapy and preterm birth

BACKGROUND

Clinical evidence suggests an association between preterm birth and periodontal disease. This study explores whether specific genetic polymorphisms are associated with success of periodontal therapy in pregnant women with periodontal disease and, further, whether any of these same polymorphisms are also associated with spontaneous preterm birth (sPTB).

METHODS

One hundred sixty high-risk pregnant women (6 to 20 weeks of gestation) with periodontal disease (≥ 3 sites with attachment loss ≥ 4 mm) were studied. All women received scaling and root planing plus oral hygiene instruction. Periodontal examinations were performed before treatment and 20 weeks later. Participants were classified according to two study outcomes: 1) success or failure of periodontal treatment; and 2) presence or absence of sPTB. Maternal DNA samples from mucosal swabs were characterized using a 1536-SNP (single-nucleotide polymorphism) custom polymerase chain reaction chip. A probabilistic model of each dichotomous outcome, derived using a stepwise Bayesian procedure, was compared to respective null hypotheses on the basis of Monte Carlo simulations and significance estimates obtained using three measures (z-test, Welch t-test, and probability convolution). The models were further confirmed by logistic regression analyses.

RESULTS

The models revealed a significant relation between a specific polymorphism of prostaglandin E receptor 3 (a gene associated with inflammatory response) and both periodontal treatment failure (odds ratio 11.09, P <0.0002) and sPTB (odds ratio 6.89, P < 0.0032).

CONCLUSIONS

These results demonstrate that the risk of unsuccessful periodontal treatment is associated with tag SNPs in specific genes that regulate the inflammatory response, one of which is also associated with sPTB.

Oral health and oral diseases in pregnancy: a multicentre survey of Italian postpartum women

BACKGROUND

The aim of this study was to explore the oral hygiene practices and oral health status of Italian postpartum women.

METHODS

A self-administered questionnaire assessed socio-demographic information, oral hygiene habits and frequency of dental visits. All women received a thorough oral examination within five days after delivery. Logistic regression models were used to estimate odds ratios and 95% confidence intervals for exposures of interest and the presence of 'severe' periodontitis.

RESULTS

Seven hundred and fifty women participated in the study; 99.1% brushed their teeth everyday and 59.9% visited the dentist annually. The mean frequency of sites with bleeding on probing was 16.1% and the median clinical attachment level was 2.1 mm. The mean caries experience score (DMFT) was 8. Severe periodontal disease was present in 21.9% of individuals. Patients who reported visiting a dentist only when in pain and women with three dental caries or more were significantly more likely to have periodontitis (OR: 1.6; 95% CI: 1.1-2.2; p < 0.05 and OR: 2.3; 95% CI: 1.5-3.5; p < 0.01, respectively).

CONCLUSIONS

Given the possible association between maternal and infant oral health, and between periodontal infection and general health, antenatal care providers should collaborate with dentists to encourage all pregnant women to comply with the oral health professionals' recommendations regarding appropriate dental brushing techniques and the importance of dental visits.

Women's oral health: why sex and gender matter

This article examines the differences and interaction between sex and gender, and how they affect women's oral and general health. The authors provide a definition of women's health, and examples of how this definition can be used to describe various oral health conditions and diseases in women. The article reviews the research on sex and gender and provides examples of their interactions. Examples of oral diseases that affect primarily women are reviewed. Advice for clinicians on the diagnosis, management, and prevention of these conditions is provided.

Oral health and dental care during pregnancy

Current research shows that women tend to receive less dental care than usual when they are pregnant. In 2012, the first national consensus statement on oral health care during pregnancy was issued, emphasizing both the importance and safety of routine dental care for pregnant women. This article reviews the current recommendations for perinatal oral health care and common oral manifestations during pregnancy. Periodontal disease and its association with preterm birth and low birth weight are also discussed, as is the role played by dental intervention in these adverse outcomes.
