Oral Health Interventions During Pregnancy

Leveraging Dental Stem Cells for Oral Health during Pregnancy: A Concise Review

Pregnancy induces significant changes in oral health because of hormonal fluctuations, making it a crucial period for preventive measures. Dental stem cells (DSCs), particularly those derived from the dental pulp and periodontal ligaments, offer promising avenues for regenerative therapies and, possibly, preventive interventions. While the use of DSCs already includes various applications in regenerative dentistry in the general population, their use during pregnancy requires careful consideration. This review explores recent advancements, challenges, and prospects in using DSCs to address oral health issues, possibly during pregnancy. Critical aspects of the responsible use of DSCs in pregnant women are discussed, including safety, ethical issues, regulatory frameworks, and the need for interdisciplinary collaborations. We aimed to provide a comprehensive understanding of leveraging DSCs to improve maternal oral health.

Race, Ethnicity, and Other Barriers to Access Dental Care During Pregnancy

BACKGROUND

Historically, women of color showed poorer oral health and lower dental service utilization in the USA. These barriers to dental care during pregnancy included dental coverage, primary language, dental provider availability, safety concerns, affordability of dental care, and perceived oral health benefits during pregnancy.

METHODS

The purpose of this study is to examine whether race/ethnicity modified the associations between barriers to accessing dental care and dental service utilization during pregnancy. This cross-sectional study sample included 62,189 women aged 20 and older with a recent birth history in 21 states from the Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2016 to 2019. We introduced a race/ethnicity by barrier interaction term to our multiple logistic regression models.

RESULTS

After adjusting for other confounders, dental insurance during pregnancy and perceived oral health benefits were associated with 4.0- and 5.6-fold higher odds, respectively, of dental service utilization during pregnancy. Statistically significant effect modification by race/ethnicity was observed in crude and adjusted analyses of the relationship between dental service utilization for all barriers included in the interaction analyses with all adjusted p-values < 0.001.

CONCLUSION

The interaction analysis found that racial/ethnic disparity in visiting dentists during pregnancy was significant among women who reported these dental barriers. In contrast, such racial/ethnic disparity was substantially attenuated among women who did not report such barriers.

PRACTICAL IMPLICATIONS

The observed racial/ethnic disparities could be mitigated by such supporting mechanisms: dental coverage, provider availability and willingness to treat pregnant women, oral health education on the safety of dental care during pregnancy, and affordable dental care costs.

Clinical Use of Paraprobiotics for Pregnant Women with Periodontitis: Randomized Clinical Trial

Periodontal disease is very common in pregnant women. Paraprobiotics are a subset of probiotics. They can be defined as inactivated microbial cells providing health benefits to the host and are considered particularly safe. The aim of this study was to compare the periodontal health of pregnant women and puerperae after 6 months of home use of paraprobiotics. A total of 30 pregnant women were enrolled and divided into two groups: the test group, who had to use a paraprobiotic-based toothpaste (Biorepair Peribioma Pro, Coswell S.p.A., Funo di Argelato, BO, Italy) and mousse (Mousse Mouthwash Biorepair Peribioma, Coswell S.p.A.) twice a day, and the control group, who had to use only the paraprobiotic-based toothpaste. The time frames of the study were: 1 month (T1), 3 months (T2) and 6 months (T3), and data were collected during pregnancy and in the period immediately following delivery. The following indices were evaluated at T0, T1, T2 and T3: clinical attachment loss (CAL), probing pocket depth (PPD), bleeding on probing (BOP), plaque control record (PCR), modified marginal gingival index (mMGI), papillary marginal gingival index (PMGI) and recessions (R). All data were subjected to statistical analysis. PCR decreased significantly from T0 to T1 in the control group and from T0 to T2 and from T0 to T3 in the test group. BOP tended to decrease in both groups, but a significant reduction was observed only in the test group. CAL, PPD, PMGI and mMGI tended to decrease gradually in both groups without significant differences between or within groups. The combination of the paraprobiotic-based toothpaste and the paraprobiotic-based mousse significantly reduced BoP and plaque control over time, although there were no significant differences with the use of the paraprobiotic-based toothpaste alone. In addition, the combination of the two products promoted a trend towards the better stabilization of recessions.

Canadian dentists' awareness and views on early childhood caries and its prevention and management

Introduction

The Canadian Dental Association (CDA) recommends children visit a dentist within 6 months of the eruption of their first tooth or by 12 months of age. The aim of this study was to investigate Canadian dentists' awareness and views on early childhood caries (ECC) and its prevention and management.

Methods

This study analyzed a subset of questions relating to dentists' knowledge of ECC and prevention strategies, from a national survey of general and pediatric dentists, commissioned by the CDA in 2013. Analyses included descriptive, bivariate, and multivariate analyses. A p-value of ≤0.05 was considered significant.

Results

Three thousand two hundred thirty-two out of 14,747 dentists responded (response rate of 21.9%), with 95.1% having heard of ECC. Overall, 60.9% of respondents reported that they were comfortable providing treatment to children with ECC. Significant differences were found between the number of years in practice and whether dentists were or were not comfortable providing prevention (19.5 ± 12.6 years vs. 25.4 ± 12.1 years; p < 0.001) or treatment for patients with ECC (19.1 ± 12.7 years vs. 22.5 ± 12.3 years; p < 0.001). Pediatric dentists (OR = 6.92; 95% CI: 2.57, 18.61), female dentists (OR = 1.13; 95% CI: 1.03, 1.24), dentists practicing in smaller urban areas (OR = 1.17; 95% CI: 1.07, 1.28), and dentists who were aware of the CDA's position on ECC (OR = 1.26; 95% CI: 1.13, 1.41) were more likely to be comfortable providing treatment for children with ECC.

Conclusions

While the majority of Canadian dentists have sufficient knowledge of ECC, not all are comfortable providing oral health care services to children at a young age. It is encouraging however, that most dentists are wanting additional oral health resources designed for education on ECC prevention for parents of young children.

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.

Metagenomic analysis examines oral microbiome changes and interplay with immune response following prenatal total oral rehabilitation

BACKGROUND

Suboptimal maternal oral health during pregnancy is potentially associated with adverse birth outcomes and increased dental caries risks in children. This study aimed to assess the oral microbiome and immune response following an innovative clinical regimen, Prenatal Total Oral Rehabilitation (PTOR), that fully restores women's oral health to a "disease-free status" before delivery.

METHODS

This prospective cohort study assessed 15 pregnant women at baseline and 3 follow-up visits (1 week, 2 weeks, and 2 months) after receiving PTOR. The salivary and supragingival plaque microbiomes were analyzed using metagenomic sequencing. Multiplexed Luminex cytokine assays were performed to examine immune response following PTOR. The association between salivary immune markers and oral microbiome was further examined.

RESULTS

PTOR was associated with a reduction of periodontal pathogens in plaque, for instance, a lower relative abundance of Tannerella forsythia and Treponema denticola at 2 weeks compared to the baseline (p < 0.05). The alpha diversity of plaque microbial community was significantly reduced at the 1-week follow-up (p < 0.05). Furthermore, we observed significant changes in the Actinomyces defective-associated carbohydrate degradation pathway and Streptococcus Gordonii-associated fatty acid biosynthesis pathway. Two immune markers related to adverse birth outcomes significantly differed between baseline and follow-up. ITAC, negatively correlated with preeclampsia severity, significantly increased at 1-week follow-up; MCP-1, positively correlated with gestational age, was elevated at 1-week follow-up. Association modeling between immune markers and microbiome further revealed specific oral microorganisms that are potentially correlated with the host immune response.

CONCLUSIONS

PTOR is associated with alteration of the oral microbiome and immune response among a cohort of underserved US pregnant women. Future randomized clinical trials are warranted to comprehensively assess the impact of PTOR on maternal oral flora, birth outcomes, and their offspring's oral health.

Investigating the impact of oral health on pregnancy and offspring outcomes: protocol for the Lifetime Impact of ORal heAlth (LIORA) cohort study

INTRODUCTION

Oral health is a fundamental component of well-being, and is closely associated with overall health and quality of life. Oral health may also affect the next generation. The children of mothers with poor oral health are likely to also have poor oral health as they go through life. We aim to investigate associations between maternal oral health and general health, pregnancy outcomes, offspring oral health and offspring general health.

METHODS AND ANALYSIS

The Lifetime Impact of Oral Health study is a prospective, observational cohort study being done at a single centre in Chongqing, China. A total of 1000 pregnant women will be recruited in their first trimester (11-14 weeks gestation). After obtaining informed consent, general and oral health assessments will be undertaken. Maternal lifestyle, demographic data and biospecimens (blood, hair, urine, nail clippings, saliva, dental plaque, buccal, vaginal and anal swabs) will be collected. Pregnancy outcomes will be recorded at the time of delivery. Cord blood and placenta samples will be collected. The offspring will be followed up for general and oral health examinations, neurodevelopmental assessments and biospecimen (dental plaque, saliva, buccal swabs, exfoliated primary dentition, urine, hair, nail clippings) collection until they are 15 years old. Biological samples will undergo comprehensive metabolomic, microbiome and epigenome analyses. Associations between maternal oral health and general health, pregnancy outcomes, offspring oral health and offspring general health will be investigated and the underlying mechanisms explored.

ETHICS AND DISSEMINATION

This project has been approved by the Research Ethics Committee of the Affiliated Hospital of Stomatology of Chongqing Medical University (CQHS-REC-2021 LSNo.23). Participants will be required to provide informed consent to participate in the study. Dissemination of findings will take the form of publications in peer-reviewed journals and presentations at national and international conferences.

Prevalence of periodontal disease in pregnancy: A systematic review and meta-analysis

OBJECTIVES

The purpose of this study was to systematically assess the epidemic trend of periodontal disease in pregnancy.

DATA

Eligibility criteria comprised studies that reported periodontitis and the periodontal indicators of BOP (+) or CAL≥4 mm or PD≥4 mm among pregnant women. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied where applicable. Risk of bias was assessed using the Critical Appraisal Checklist for prevalence studies proposed by The Joanna Briggs Institute (JBI). Meta-analyses were conducted to estimate the pooled effect measures. Q-statistic, I² statistic, subgroup and sensitivity analyses assessed study heterogeneity.

SOURCES

Electronic search of articles was conducted using PubMed, Web of Science, EMBASE, Scopus, and Ovid from January 2000 to January 2022.

RESULTS

A total of 20 studies were included in the meta-analysis. The prevalence of periodontitis among pregnancy was 40% (95% Confidence Interval (CI): [0.15, 1.00]). The prevalence rates were 67% (CI [0.56, 0.80]), 42% (CI [0.27, 0.57]) and 24% (CI [0.12, 0.37]) for BOP (+), PD≥4 mm and CAL≥4 mm respectively. Regarding subgroup meta-analyses, the prevalence rates of BOP (+) and PD≥4 mm presented a gradual increase throughout pregnancy, while the highest prevalence rate of CAL≥4 mm was in the 2nd trimester.

CONCLUSIONS

It was observed a high prevalence of periodontal disease in pregnancy. However, heterogeneity was high among included studies. More high-quality epidemiologic investigations on periodontal disease in pregnancy are still needed.

CLINICAL SIGNIFICANCE

Periodontal disease in pregnancy is highly prevalent which results in a reduced quality of life, frequent systemic pathologies and adverse pregnancy outcomes. Given the unhealthy consequences, public health impact, and expansive disease burden, it is worthwhile to investigate more aspects of periodontal disease during pregnancy.

Impact of a Maternal Motivational Interviewing on Oral Health in the Mother-Child Dyad

Motivational Interviewing (MI) has been included in dentistry programs. There exists a need for interventions in the mother-child dyad. The aim of this paper was to compare the effects of a MI-based educational program on oral care knowledge, attitudes, and practices (KAP) in the mother-child dyad to a Traditional Education-based program (TE). A community intervention trial was carried out. The experimental and control groups were made up of women between 18 and 45 years of age in the sixth month of gestation. Both groups were provided with TE. The experimental group additionally received a session based on the principles of the MI. Socio-demographic data, children’s oral health KAP (COHKAP), that of the mother (MOHKAP), and maternal self-efficacy (MSE) in relation to children’s oral health (COHMSE) were recorded. A baseline measurement was made, as well as a six-month follow up. The participants included 135 women with an average age of 24.88 ± 6.00. After intervention, the experimental group’s COHKAP, MOHKAP, and COHMSE all increased (p < 0.001). When MI-based interventions are combined with TE, MSE and dental care KAP for the mother-child dyad in pregnant women can be improved.

Oral Hygiene Practice among Hospitalized Patients: An Assessment by Dental Hygiene Students

Aim: An epidemiological study was carried out, in hospital wards, with the aim of assessing the oral health status of patients subjected to multiple medical treatments. Material and Methods: The study was conducted at Fondazione IRCCS Policlinico San Matteo (Pavia, Italy). A questionnaire was submitted to patients for the evaluation of oral hygiene devices used; then, a clinical examination was conducted to collect Decayed Missing Filled Teeth (DMFT) index, Plaque Index (PI), and Marginal Gingival Index (MGI) values. Results: Manual toothbrushes were used by a wide range of the sample study (65–100% among hospital wards), together with mouthwash (20–80%); interproximal aids were used by few patients (the lowest recorded value was 33.3%). Conclusion: dental hygienists could be integrated into hospital wards as oral hygiene procedure instructors, for the improvement of the oral health conditions of hospitalized patients.

Dental care utilization during pregnancy by Medicaid dental coverage in 26 states: Pregnancy risk assessment monitoring system 2014-2015

OBJECTIVE

To examine the association between Medicaid dental coverage for adult pregnant women with dental care utilization during pregnancy.

METHODS

Pregnancy risk assessment monitoring system (PRAMS) data (2014-2015) and the Medicaid-SCHIP state dental association (MSDA) national profiles (2014-2015) were used in this study. The study sample included 16,612 Medicaid-enrolled women, for a weighted number of 965,046 women from 26 states and New York City. State Medicaid dental coverage was categorized into (1) no coverage for the dental cleaning, (2) coverage for dental cleaning and fillings, (3) extended dental coverage. The adjusted prevalence ratios (aPR) for dental visits for cleaning during pregnancy were examined by Medicaid dental coverage level.

RESULTS

Medicaid-enrolled women in states with no dental coverage were less likely to visit dentists for cleaning during pregnancy (26.7%) compared with women in states with either limited dental coverage (36.6%) or extended dental coverage (44.9%). Compared with women in state without dental coverage, Medicaid-enrolled women in states with extended dental coverage (aPR = 1.20, 95% CI [1.16-1.23]) and women in states with limited coverage (aPR = 1.10, 95% CI [1.06-1.14]) were more likely to visit dentists for cleaning during pregnancy when adjusted for other sociodemographic variables and adequacy of prenatal care. A similar pattern of association was observed for a dental visit to address dental problems during pregnancy.

CONCLUSIONS

This study highlights the importance of Medicaid dental coverage for adult pregnant women related to dental service utilization during pregnancy.

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.

Sociodemographic, Behavioral and Oral Health Factors in Maternal and Child Health: An Interventional and Associative Study from the Network Perspective

Oral healthcare during pregnancy needs to be part of the assistance routine given to pregnant women by health professionals as a way to encourage self-care and strengthen the general health of the mother and the baby. The aim of this study was to evaluate the effectiveness of an integrated oral healthcare intervention for pregnant women and to analyze the association of sociodemographic, behavioral, oral health and general maternal and child health factors in prenatal care at usual risk in primary care in a city in the northeast of Brazil, in 2018–2019. A controlled, randomized, single-blinded community trial was conducted. The intervention group (IG) received dental assistance and collective health education actions in conversation circles, while the control group (CG) received the usual assistance. All pregnant women (146 in total, 58 from IG and 88 from CG) that took part in the trial answered a questionnaire and underwent a dental examination at the beginning of prenatal care and at the puerperal visit. To assess the effect of the intervention, a network analysis was used. The results have shown that being in the control group was associated with neonatal complications (0.89) and prematurity (0.54); the use of tobacco and alcohol are associated with high risk in initial and final oral health; lower educational level of the pregnant women implicates high risk for initial oral health (−0.19), final oral health (−0.26), pregnancy complications (−0.13), low birth weight (−0.23), prematurity (−0.19) and complications in the newborn (−0.14). Having a low family income (≤261.36 USD) has shown a high risk for initial oral health (−0.14), final oral health (−0.20) and prematurity (−0.15). The intervention based on integrated oral healthcare for pregnant women indicated that socioeconomic and behavioral factors must be considered as determinants for the quality of women and children’s health and that multi-professional performance during prenatal care contributes to the positive outcomes of pregnancy.

Interprofessional collaboration and smartphone use as promising strategies to improve prenatal oral health care utilization among US underserved women: results from a qualitative study

Background

Data on barriers and facilitators to prenatal oral health care among low-income US women are lacking. The objective of this study was to understand barriers/facilitators and patient-centered mitigation strategies related to the use of prenatal oral health care among underserved US women.

Methods

We used community-based participatory research to conduct two focus groups with eight pregnant/parenting women; ten individual in-depth interviews with medical providers, dental providers and community/social workers; and one community engagement studio with five representative community stakeholders in 2018–2019. Using an interpretive description research design, we conducted semi-structured interviews and focus groups which were audio-recorded, transcribed, and analyzed for thematic content.

Results

We identified individual and systemic barriers/facilitators to the utilization of prenatal oral health care by underserved US women. Strategies reported to improve utilization included healthcare system-wide changes to promote inter-professional collaborations, innovative educational programs to improve dissemination and implementation of prenatal oral health care guidelines, and specialized dental facilities providing prenatal oral health care to underserved women. Moreover, smartphones have the potential to be an innovative entry point to promote utilization of prenatal oral care at the individual level.

Conclusions

Low-income women face multiple, addressable barriers to obtaining oral health care during pregnancy. Inter-professional collaboration holds strong promise for improving prenatal oral health care utilization.

Disparities in Access to Oral Health Care

In the United States, people are more likely to have poor oral health if they are low-income, uninsured, and/or members of racial/ethnic minority, immigrant, or rural populations who have suboptimal access to quality oral health care. As a result, poor oral health serves as the national symbol of social inequality. There is increasing recognition among those in public health that oral diseases such as dental caries and periodontal disease and general health conditions such as obesity and diabetes are closely linked by sharing common risk factors, including excess sugar consumption and tobacco use, as well as underlying infection and inflammatory pathways. Hence, efforts to integrate oral health and primary health care, incorporate interventions at multiple levels to improve access to and quality of services, and create health care teams that provide patient-centered care in both safety net clinics and community settings may narrow the gaps in access to oral health care across the life course.

Role of diet in ECC affected South Indian children assessed by the HEI-2005: A pilot study

BACKGROUND

"Early Childhood Caries"(ECC) is a serious global oral health problem affecting children of 71 months of age or younger. ECC has a multifactorial model of causation and diet imparts an intricately specific effect.

AIM

The study aims to determine the protective and harmful role of different dietary consumption in the causation of ECC in South Indian children, assessed by the Healthy Eating Index-2005 (HEI-2005).

SETTINGS AND DESIGN

A pilot study of cross-sectional analytical study design was conducted in a dental college and hospitals in India.

MATERIALS AND METHODS

Hundred healthy South Indian children of 3-6 years age were screened for dental caries by the ICDAS II criteria, dmf/dmfs and pufa index. Participants were divided into three groups according to their caries status such as [Group 1:caries-free, group 2:ECC, group 3:severe ECC (S-ECC)]. Questionnaires were collected with demographic details, 24 h previous dietary record, and a subsequent 3-day chart of dietary consumption. Accordingly, the HEI-2005 score was calculated for each participant. Descriptive statistics was used for analysis of sociodemographic data, Kruskal-Wallis test for multivariate analysis, and for interpreting the total effect of HEI on study groups, logistic regression analysis was used.

RESULTS

Caries experience in South Indian children demonstrated a significant association with age. Caries-free children showed significantly higher association with darkgreen/orange vegetables/legumes, milk, and calories from SoFAAS (solid fat, alcohol, and added sugars) than the other groups.

CONCLUSIONS

The study findings illustrated a prominent protective role played by specific components of the HEI-2005, as healthy dietary intake against dental caries in South Indian children.

Perinatal Oral Health: A Novel Collaborative Initiative to Improve Access, Attitudes, Comfort Level, and Knowledge of Pregnant Women and Dental Providers

Objectives  The objectives of this program were to increase access to dental care among pregnant women and to improve dental students' exposure, comfort level, and knowledge of the potential impact of poor oral health on pregnancy outcomes. Study Design  Through collaborative efforts of a School of Dentistry and a School of Medicine, the Oral Health Pregnancy Day Initiative (OHPDI) was developed. Dental students were educated on the impact poor oral health may have on pregnancy outcomes and the importance of access to care. Pregnant women received perinatal oral health education and needed dental care. Results  Thirty-four pregnant women presented for the OHPDI. Thirty-nine dental students participated. Eighty-five percent of students reported they learned how poor oral health may have a negative impact on pregnancy and birth outcomes; 79% agreed as a result of the event they were more likely to treat pregnant women. Ninety-four percent of pregnant women reported not having a dentist and 100% received perinatal oral health education and needed dental care. Eighty-eight pregnant women were seen subsequent to the OHPDI. Conclusion  This initiative resulted in increased students' knowledge, exposure, and comfort level to treating pregnant women and pregnant women received needed oral health care education and dental treatment.

Prenatal Oral Health Care and Early Childhood Caries Prevention: A Systematic Review and Meta-Analysis

Despite the advancement of early childhood caries (ECC) prediction and treatment, ECC remains a significant public health burden in need of more effective preventive strategies. Pregnancy is an ideal period to promote ECC prevention given the profound influence of maternal oral health and behaviors on children's oral health. However, studies have shown debatable results with respect to the effectiveness of ECC prevention by means of prenatal intervention. Therefore, this study systematically reviewed the scientific evidence relating to the association between prenatal oral health care, ECC incidence, and Streptococcus mutans carriage in children. Five studies (3 randomized control trials, 1 prospective cohort study, and 1 nested case-control study) were included for qualitative assessment. Tested prenatal oral health care included providing fluoride supplements, oral examinations/cleanings, oral health education, dental treatment referrals, and xylitol gum chewing. Four studies that assessed ECC incidence reduction were included in meta-analysis using an unconditional generalized linear mixed effects model with random study effects and age as a covariate. The estimated odds ratio and 95% confidence intervals suggested a protective effect of prenatal oral health care against ECC onset before 4 years of age: 0.12 (0.02, 0.77) at 1 year of age, 0.18 (0.05, 0.63) at 2 years of age, 0.25 (0.09, 0.64) at 3 years of age, and 0.35 (0.12, 1.00) at 4 years of age. Children's S. mutans carriage was also significantly reduced in the intervention group. Future studies should consider testing strategies that restore an expectant mother's oral health to a disease-free state during pregnancy.

A Developmental Approach to Pediatric Oral Health

Orofacial growth and development is a complex process spanning the life course. This article provides an oral health overview in the context of overall growth, physical and social development from infancy through adolescence. It reviews oral health-specific developmental milestones during childhood (0-12 years) and adolescence (≥13 years). It examines issues particular to each age category or spanning multiple ages (eg, pediatric overweight and obesity, tobacco use, and dental trauma) in relation to oral health and development. In addition, the oral microbiome and its potential role in informing personalized oral health care across the life course is discussed.

An Umbrella Review Exploring the Effect of Periodontal Treatment in Pregnant Women on the Frequency of Adverse Obstetric Outcomes

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.
