Periodontal treatment during pregnancy and birth outcomes: a meta‐analysis of randomised trials

OBJECTIVE The objective of this review was to conduct a meta-analysis of all up-to-date randomised control trials to determine whether periodontal treatment during pregnancy has the potential of reducing preterm birth and low birth weight incidence. METHODS Bibliographic databases MEDLINE (1966-present), EMBASE (1980-present), CINAHL (1982-present) and the Cochrane library up to and including 2010 Issue 10 were searched. The reference list of included studies and reviews were also searched for additional literature. Eligible studies were, published and ongoing randomised control trials that compared pregnancy outcomes for pregnant women who received periodontal treatment during the prenatal period. Two of the investigators independently assessed the studies and then extracted and summarised data from eligible trials. Extracted data were entered into Review Manager software and analysed. RESULTS A total of 5645 pregnant women participated in the 10 eligible trials. Meta-analysis found that periodontal treatment significantly lowered preterm birth (odd ratio 0.65; 95% confidence interval, 0.45-0.93; P = 0.02) and low birth weight (odd ratio 0.53; 95% confidence interval, 0.31-0.92; P = 0.02) rates while no significant difference was found for spontaneous abortion/stillbirth (odd ratio 0.71; 95% confidence interval, 0.43-1.16; P = 0.17). Moderate heterogeneity was observed among the studies for preterm birth and low birth weight. Subgroup analysis showed significant effect of periodontal treatment in pregnant women with low rate of previous preterm birth/low birth weight (odd ratio 0.35; 95% confidence interval, 017-0.70; P = 0.003) and less severe periodontal disease (odd ratio 0.49; confidence interval, 028-0.87; P = 0.01) as defined by probing depth. CONCLUSION The cumulative evidence suggests that periodontal treatment during pregnancy may reduce preterm birth and low birth weight incidence. However, these findings need to be further validated through larger more targeted randomised control trials.

Promoting oral health during pregnancy: current evidence and implications for Australian midwives.

AIMS AND OBJECTIVES The aim of this paper is to examine current evidence supporting the promotion of oral health during pregnancy and proffer aspects of a potential role for Australian midwives. BACKGROUND Research continues to show that poor oral health during pregnancy can have an impact on the health outcomes of the mother and baby. Poor maternal oral health increases the chances of infants developing early caries and is strongly associated with adverse pregnancy outcomes such as preterm and low birth-weight babies. Unfortunately in Australia, no preventive strategies exist to maintain the oral health of pregnant women. DESIGN Systematic review. METHOD This review examines all literature on oral health during pregnancy published to date in the English language and focuses on whether preventive oral health strategies during the prenatal period are warranted in Australia and if so, how they could be provided. RESULTS Maintaining oral health is important during pregnancy and many developed countries have implemented preventive strategies to address this issue using non-dental professionals such as prenatal care providers. However, despite the positive international evidence, limited importance is being given to the oral health of pregnant women in Australia. It is also evident that the unique potential of prenatal care providers such as midwives to assess and improve maternal oral heath is not being thoroughly utilised. Compounding the issue in Australia, especially for pregnant women from socioeconomically disadvantaged backgrounds, is the limited access to public dental services and the high cost of private dental treatment. CONCLUSION Promoting and maintaining oral health during pregnancy is crucial, and preventive prenatal oral health services are needed in Australia to achieve this. RELEVANCE TO CLINICAL PRACTICE Midwives have an excellent opportunity to offer preventive oral health services by providing oral health assessments, education and referrals for pregnant women attending antenatal clinics.

The oral health status, practices and knowledge of pregnant women in South-western Sydney

BACKGROUND Current evidence highlights the importance of oral health during pregnancy. However, little is known about the oral health of pregnant women in Australia. The aim of this study was to report the oral health status, knowledge and practices of pregnant women in south-western Sydney. METHODS A cross-sectional survey of 241 pregnant women attending a large hospital in south-western Sydney. RESULTS More than half (59.3%) reported dental problems during pregnancy, less than a third (30.5%) saw a dentist in the last six months, only 10% had received any information about perinatal oral health and many (>50%) were unaware of the potential impact of poor maternal oral health on pregnancy and infant outcomes. Analysis revealed a significant difference (<0.05) in the uptake of dental services among pregnant women who had higher household incomes, private health insurance, received information about perinatal oral health and knowledge about maternal oral health. CONCLUSIONS The participants reported significant barriers to obtaining dental care including limited access to affordable dental services and lack of awareness about the importance of maternal oral health. The findings suggest the need for preventive strategies involving dentists and antenatal providers to improve maternal oral health in Australia.

Midwives and oral health care during pregnancy: perceptions of pregnant women in south-western Sydney, Australia.

AIMS AND OBJECTIVE This study sought to explore the perceptions of pregnant women in Australia towards oral health care during pregnancy and their views regarding midwives providing oral health education, assessment and referrals as part of antenatal care. BACKGROUND Maintaining oral health during pregnancy is important. Yet, many pregnant women do not access dental services during this time. Antenatal care providers are now recommended to promote maternal oral health, and various countries have adopted this strategy. However, in Australia, a lack of emphasis is placed on maternal oral health especially by antenatal care providers. Currently, a preventive programme is being developed to promote maternal oral health with the help of midwives in Australia. Very little is known about the perceptions of such an approach from pregnant women. DESIGN Qualitative approach. METHOD Data were collected via semi-structured telephone interviews with 10 pregnant women residing in south-western Sydney. RESULTS Thematic analyses of the data suggest a high prevalence of poor oral health among pregnant women, especially those socioeconomically disadvantaged. The findings also highlight various barriers deterring these women from seeking dental care the most significant being lack of dental awareness, high treatment costs and misconceptions about dental treatment during pregnancy. The absence of affordable dental care remains a major barrier in Australia. The proposed preventive programme was well received by women although issues such as education for midwives and referral pathways were highlighted. CONCLUSIONS The findings suggest that a tailored midwifery-initiated oral health programme has potential in Australia, especially for low-income families as it addresses many existing barriers to dental care. RELEVANCE TO CLINICAL PRACTICE Antenatal care providers in Australia should provide more information about oral health. These health professionals should be adequately educated to promote oral health. Health services should also consider offering pregnant women affordable and accessible dental services.

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.

Piloting of an oral health education programme and knowledge test for midwives

Abstract Research shows limited emphasis being placed on oral health by midwives in Australia and the need for further education in this area. The study aim was to pilot a midwifery oral health education programme and knowledge test and identify any flaws in its content and design. Twenty-two midwives from an antenatal ward in South-Western Sydney completed the programme and 12 feedback forms/knowledge tests were returned. Data was analysed using descriptive statistics and content analysis. Feedback data showed all midwives appreciated that the programme was available online and self-paced. Most found the programme extremely informative and following completion were more confident in promoting maternal oral health. The mean correct responses in the knowledge test was 79% (SD = 12.3) which suggests most items were suitable for assessing knowledge improvement. However, in three items midwives had low correct responses. Various aspects that could be improved or clarified were identified and suggestions discussed.

The midwifery initiated oral health-dental service protocol: an intervention to improve oral health outcomes for pregnant women

BackgroundEvidence is emerging that women’s poor oral health and health practices during pregnancy are associated with poor oral health in their children and potentially an increased risk of pre-term or low-birth weight infants.Methods/DesignThe Midwifery Initiated Oral Health-Dental Service (MIOH-DS) trial is a three arm multicentre randomised controlled trial which will recruit women from three metropolitan hospitals aimed at improving women’s oral health and service access and indirectly reducing perinatal morbidity. All three arms of the trial will deliver oral health promotion material, although a midwife oral assessment and referral to private/public/health fund dental services pathway (Intervention Group 1) and the midwife oral assessment and referral to local free public dental services pathway (Intervention Group 2) will be compared to the control group of oral health promotional material only. Midwives will undergo specific oral health education and competency testing to undertake this novel intervention.DiscussionThis efficacy trial will promote a new partnership between midwives and dentists focused on enhancing the oral health of women and their infants. Should the intervention be found effective, this intervention, with existing on-line educational program for midwives, can be easily transferred into practice for large metropolitan health services within and beyond Australia. Further cost-benefit analysis is proposed to inform national health policy.Trial registrationAustralian New Zealand Clinical Trials Registry ACTRN12612001271897.

Views of pregnant women in South Western Sydney towards dental care and an oral-health program initiated by midwives

ISSUES ADDRESSED Oral health during pregnancy is important, yet is often neglected by women. A program is currently being developed for midwives in Australia to promote maternal oral health. The aim of this study was to record the views of pregnant women in Australia towards dental care and midwives promoting oral health. METHODS Using convenience sampling, a cross-sectional survey was undertaken of 241 pregnant women attending a metropolitan hospital in South Western Sydney in 2010. RESULTS Only 10% of women received oral-health promotional material during pregnancy. More than 50% reported dental problems, yet only 17% had discussed this with their midwives and less than half (44.6%) had sought dental treatment. The main barriers to obtaining dental care were: lack of awareness, safety concerns about dental treatment and dental costs. Pregnant women were more likely (P<0.05) to see a dentist if they had received information about oral health (odds ratio (OR) 3.25, 95% CI 1.34-7.90) and had private health insurance (OR 2.47, 95% CI 1.26-4.85). Most women (>90%) were receptive to midwives providing oral-health education, assessments and referrals to affordable dental services. CONCLUSION This study has shown that pregnant women are receiving limited dental advice and are concerned about dental costs. It has also confirmed for the first time in Australia that women are very positive about receiving oral-health advice from midwives during their pregnancy. SO WHAT?: Oral-health promotion programs during pregnancy should consider using midwives to increase dental awareness among women and provide pathways to affordable dental services.

Developing and Testing of an Oral Health Screening Tool for Midwives to Assess Pregnant Woman

Maternal oral health is important, and midwives are encouraged to screen women for dental problems. We aimed to develop and test a midwifery oral health screening tool. A three-item tool was tested as part of a trial involving 300 women in Southwestern Sydney. A two-item combination showed better sensitivity (98%) and had a positive predictive value of 88%. Specificity was 40%, and negative predictive value was 80%. A two-item screening tool has been identified that is sensitive to identifying dental problems and facilitating referrals. Further validation using a larger sample is required to reassess the tools specificity.

Evaluation of a midwifery initiated oral health-dental service program to improve oral health and birth outcomes for pregnant women: A multi-centre randomised controlled trial

BACKGROUND Oral health care during pregnancy is important for the health of the mother and child. However, pregnant women have limited knowledge about maternal oral health and seldom seek dental care. Further, due to limited training antenatal care providers like midwives rarely discuss oral health with pregnant women. The Midwifery-Initiated Oral Health Dental Service program was developed to address current gaps in oral promotional interventions during pregnancy. OBJECTIVES To assess the effectiveness of a Midwifery-Initiated Oral Health Dental Service program in improving uptake of dental services, oral health knowledge, quality of oral health, oral health status and birth outcomes of pregnant women. DESIGN Multi-centre randomised controlled trial. SETTING Three large metropolitan public hospitals in Sydney, Australia. PARTICIPANTS Pregnant women attending their first antenatal appointment who were at least 18 years old and had a single low risk pregnancy between 12 and 20 weeks gestation. METHODS 638 pregnant women were allocated to three groups using block randomisation (n = 211) control group, intervention group 1 (n = 215), intervention group 2 (n = 212) and followed up till birth. Study investigators and data collectors were blinded to group allocation. Intervention group 1 received a midwifery intervention from trained midwives involving oral health education, screening and referrals to existing dental pathways. Intervention group 2 received the midwifery intervention and a dental intervention involving assessment/treatment from cost free local dental services. The control group received oral health information at recruitment. Primary outcome was uptake of dental services. Secondary outcomes included oral health knowledge, quality of oral health, oral health status and birth outcomes. RESULTS Substantial improvements in the use of dental services (20.2% Control Group; 28.3% Intervention group 1; 87.2% Intervention group 2; Odds Ratio Intervention group 2 vs Control Group = 29.72, 95% CI 15.02-58.53, p < 0.001), womens oral health knowledge (p = 0.03); quality of oral health (p < 0.001) and oral health outcomes (sulcus bleeding, dental plaque, clinical attachment loss, decayed/filled teeth- p < 0.001) were found in Intervention group 2. No difference in the rate of preterm or low-birth weight was found. CONCLUSIONS The Midwifery-Initiated Oral Health Dental Service program (Intervention group 2) improved the uptake of dental services and oral health of pregnant women and is recommended during antenatal care. A cause and effect relationship between this intervention and improved birth outcomes was not supported.
