Dental pain and associated factors among pregnant women: an observational study

Pain, anxiety, and catastrophizing among pregnant women with dental pain, undergoing root canal treatment

This prospective study aims to evaluate dental pain, anxiety, and catastrophizing levels in pregnant women undergoing root canal treatment. Sixty pregnant and non-pregnant women presenting dental pain and an indication for root canal treatment were included in the study. Dental anxiety and catastrophizing were investigated using validated questionnaires. The endodontic intervention was performed, and a numerical scale measured preoperative and postoperative dental pain. The results were analyzed using STATA software 12.0. Unadjusted analyses assessed the association between pregnancy and pain, anxiety, and catastrophizing levels. Multiple linear regression models using 'forward stepwise' entry procedures were used to assess the independent effects of variables on pain scores. The significance level was set at 0.05. Initially, most patients experienced intense dental pain. The levels of dental pain, dental anxiety, and catastrophizing did not differ between pregnant and non-pregnant women. Logistic regression showed that postoperative pain was associated with irreversible pulpitis diagnosis (OR = 4.78; 95%CI 1.55-13.55) and high catastrophizing levels (OR = 1.96; 95%CI 1.01-3.84). Preoperative and postoperative pain rates and anxiety and catastrophizing were similar between pregnant and non-pregnant patients. Postoperative pain was associated with irreversible pulpitis diagnosis and high catastrophizing levels. The similarity between pregnant and non-pregnant women regarding preoperative and postoperative dental pain and catastrophizing and anxiety levels supports the indication of root canal treatment during the gestational period whenever necessary.

Perceptions, knowledge, and practices related to oral health in a group of pregnant women: A qualitative study

BACKGROUND

It is well known that the prevalence of dental caries and periodontal disease is increasing in pregnant women. Dental care is mostly sufficient to prevent oral diseases and perform timely interventions. However, few pregnant women go to the dental office during this period due to a lack of knowledge. The perceptions, knowledge, and oral health practices of pregnant women have been scarcely explored and should be taken into account to propose positive interventions in this population.

OBJECTIVES

To identify and explore the perceptions, knowledge, and practices of oral health in a group of pregnant women in Colombia.

MATERIAL AND METHODS

Twenty-four semistructured interviews were conducted in different areas of Colombia. The interviews were conducted via telephone, and the calls were recorded with the consent of the participants. The recordings were transcribed in Word® and checked for typing and transcription errors. The transcripts were analyzed using a hybrid approach combining inductive and deductive coding. The information was organized and encoded using NVivo12 ®software. We followed the Standards for Reporting Qualitative Research (SRQR) checklist.

RESULTS

Pregnant women reported having good oral health. One barrier mentioned for occupation (Job) was pregnancy. The appearance of the oral cavity has not negatively affected the relationships of pregnant women.

CONCLUSIONS

The pregnant women had good oral hygiene habits but did not receive dental check-ups. Knowledge in this group was limited and diverse. The information given by health professionals should be standardized, and some beliefs should be demystified.

RELEVANCE TO CLINICAL PRACTICE

In general, few pregnant women were aware of bleeding gums during pregnancy. Empower pregnant women to take care of themselves through regular dental check-ups with the aim of preventing and treating oral diseases. Oral hygiene education and healthy nutritional habits should be intensified during this stage.

PATIENT OR PUBLIC CONTRIBUTION

The participation in the study included a semistructured interview by telephone with the prior consent of the pregnant woman authorizing her involvement and the recording of the interview.

Prevalence of dental caries in pregnant Colombian women and its associated factors

OBJECTIVE

To identify the prevalence of dental caries in pregnant women in the Colombian population and its association with the medical history and social determinants, based on data from the fourth National Oral Health Survey (ENSAB IV).

MATERIALS AND METHODS

A total of 1,047 pregnant women from different areas of Colombia were evaluated. A dental evaluation was performed using a flat oral mirror and blunt-tipped probe (World Health Organization, 2007). For diagnosis of the dental condition, the DMFT index was used. A negative binomial regression analysis was performed to evaluate the association between social determinants and the DMFT index.

RESULTS

The results of this national study show a 59% prevalence of caries in this population. Regarding the experience of caries, 89.9% of pregnant women showed having had caries.

CONCLUSIONS

The results of this national study on pregnant women show a high prevalence of dental caries. The women's level of education is an important factor associated with dental caries and filled teeth, so the role of oral health education and dental check-ups are important.

CLINICAL RELEVANCE

The findings of this study show the oral health situation of pregnant women, with a high prevalence of dental caries. This leads to the development and strengthening of oral health education strategies that empower pregnant women in their care. In addition, dental checkups during pregnancy should be implemented and reinforced to prevent and treat oral pathologies and thus prevent complications during this stage.

Social and Preventive Factors That Explain Oral Health among Pregnant Women in the Canton of Cuenca, Ecuador

(1) Background: pregnant women in underprivileged areas may face challenges that affect their oral health. The analysis of these issues such as toothaches or cavities, among others could be crucial for them. However, no studies have been conducted in Cuenca, Ecuador. Thus, this study aimed to create a model explaining how social factors and healthy habits impact oral health in Cuenca, Ecuador. (2) Methods: An observational study was performed using a questionnaire developed from scratch. Principal component factor analysis was performed to calculate the oral disease index based on the oral health issues reported by women during pregnancy. (3) Results: 1971 women participated in the research. In total, 88% reported at least one oral health problem, with cavities (34%) and bleeding gums (33%) as the most prevalent. The rate of preventive visits and frequent brushing were the two variables that most impacted the oral disease index. The consumption of sweets, age, and the belief that visiting the dentist harms their unborn child were also important factors. However, income, education, and ethnic background showed little to no effect. (4) Conclusions: The most beneficial determinants of oral health factors in pregnant women in Cuenca, Ecuador, are preventive dentist visits, frequent brushing, and a contained consumption of sweets. The main harmful factors are age and the misconception that dental visits can harm their unborn child. Surprisingly, income, education, and ethnic background have little effect. This study can be replicated in other countries and cultures.

Immunohistochemical expression of estrogen receptor alpha in the maxillary sinus, pulp, and periodontal ligament of adjacent teeth in late pregnancy in rats

This study aimed to assess the histological changes in the maxillary sinus and its adjacent dental tissues as pulp and periodontal ligament during pregnancy and investigate the role of estrogen hormone in these changes through the detection of estrogen receptors in these tissues. Sixteen adult female rats were used and were allocated into two groups: control non-pregnant (n = 8) and pregnant (n = 8). They were sacrificed and their heads were prepared for histological and immunohistochemical examination for estrogen receptor alpha. Our results revealed that pregnant rats revealed inflammatory changes in the sinus as thick epithelial lining, loss of cilia, swollen goblet cells, intraepithelial and interstitial edema. The lamina propria demonstrated considerable infiltration of inflammatory cells, glandular hyperplasia with vacuolar degeneration, and vascular congestion. Periodontal ligament and pulp revealed hyperemia and vascular congestion. Immunohistochemical examination of estrogen receptor alpha in the maxillary sinus and adjacent dental tissues (Periodontal ligament and pulp) in pregnant rats revealed a significant increase in its expression in all examined tissues. In conclusion, there was an increase in expression of ERα in the sinus mucosa and dental tissues during pregnancy together with slight inflammatory changes in these tissues. Hence, dentists should be aware of the effect of these changes on the pregnant women avoiding teeth extraction due to misdiagnosis of dental, periodontal or sinus pain after exclusion of true pathologies.

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.

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.

Anxiety/fear of dental treatment during pregnancy: use of the Modified Dental Anxiety Scale (MDAS)

BACKGROUND

Despite advances in the control of anxiety and fear, dental treatment (DT) continues to be a stressful event, especially during pregnancy. There are several instruments to measure anxiety and fear about DT (AFDT). However, few are validated for use in Brazil. Our objective was to validate the Modified Dental Anxiety Scale (MDAS) for use in Brazil and to evaluate the association between AFDT and the use of oral health services (OHS) during pregnancy.

METHODS

This is a cross-sectional study nested in a prospective cohort. We conducted a face, content, and construct validation. The Visual Analogue Scale (VAS) was the comparison instrument with MDAS. Sociodemographic and behavioral characteristics were also assessed. Associations were estimated by odds ratios (OR) and 95% confidence intervals (95%CI) in multiple logistic regression analysis (alpha=5%).

RESULTS

There were no difficulties in the translation/back-translation process. The reproducibility of the instrument was 0.54 (P=0.01). The correlation of MDAS with VAS was 0.71 (P=0.003). The reliability of the instrument was high (Cronbach's alpha: 0.79 to 0.87). After validation, the instrument was administered to 486 women. Mild or moderate AFDT was reported by 81.3% of pregnant women and at higher levels, by 8.2%. There was no association between the use of OHS and AFDT at moderate levels (OR=2.03; 95%CI: 0.45-9.09) or high (OR=1.35; 95%CI: 0.20-9.13).

CONCLUSIONS

MDAS is a valid instrument for measuring AFDT. The prevalence of AFDT among pregnant women is high, but this event does not seem to be associated with the use of OHS.

Predictors of periodontal and caries related perinatal oral healthcare, investigation of dentists' practices: a cross-sectional study

Background

The objectives of the study were to assess the knowledge, attitude, and practice of dentists towards providing oral health care to pregnant women and to identify barriers and predictors of periodontal and caries related perinatal oral healthcare practices.

Methods

A cross-sectional analytical survey was conducted on dentists by using a random sampling technique, and a pre-validated questionnaire was delivered to 350 dentists from May 2018 to October 2018. Data were analyzed by utilizing SPSS software. Frequencies and percentages were recorded for descriptive variables. Binary logistic regression was used to analyze the probability of predicting group membership to the dependent variable using different independent variables determined from contingency tables.

Results

Overall response rate was 41%. The mean knowledge score of respondents was 15.86 ± 3.34. The lowest correct responses were noted in the questions related to periodontal health. It was found that the advice to delay dental visits until after pregnancy was eight times more likely to be observed among dentists who lacked the knowledge of importance of oral health during pregnancy (P = 0.04, OR = 8.75). Dentists were more likely to consult obstetricians regarding dental procedures when they fear a risk of labor in the dental practice (P < 0.05, OR = 3.72). Dentists who had the knowledge of periodontal disease association with preterm delivery were about four times more likely to treat periodontal disease during pregnancy (P = 0.01, OR = 3.95). Dentists knowing the association between maternal oral health and childhood decay were more likely to counsel pregnant patients regarding caries prevention (P > 0.05, OR = 3.75).

Conclusions

Collectively the results indicated few gaps in knowledge among some dentists and a need to improve existing attitudes towards perinatal oral health. Dentists failing to recognize the importance of perinatal oral health are more likely to be hesitant in treating pregnant patients. Failing to recognize the link between periodontal disease and obstetric complications increases the possibility of hesitance to counsel pregnant patients regarding the same. The appreciation of the evidence for poor perinatal oral health and risk of early childhood caries increases the likelihood of counseling by dentists on caries prevention.

Na análise multivariada verificou-se que a variável avaliação das consultas de pré-natal como boa aumentou em 14% [Razão de Prevalência (RP)=1,14; Intervalo de Confiança (IC) 95%:1,01-1,27] a probabilidade de as mulheres expressarem satisfação com a variável desfecho. Conclusão Conclui-se que foi alta taxa de satisfação com as consultas odontológicas realizadas no SUS pelas gestantes e avaliação das consultas de pré-natal como boa foi fator associado. Estes resultados poderiam ser considerados durante o planejamento estratégico, execução e avaliação das políticas de saúde direcionadas para este grupo operativo.

Dental Anxiety Amongst Pregnant Women: Relationship With Dental Attendance and Sociodemographic Factors

Introduction

: Access to oral care during pregnancy is important for the maintenance of optimal oral health.

Objective

: The aim of this study was to estimate dental anxiety (DA) and its association with previous dental visits and sociodemographic factors amongst pregnant women.

Methods

: A cross-sectional study was conducted (June through August 2019) amongst pregnant women (N = 825) attending hospitals and health centres in Dhahran, Khobar, and Dammam cities in the Eastern province of Saudi Arabia. The Modified Dental Anxiety Scale (MDAS) was used to assess DA and the World Health Organization Oral Health Survey for Adults was administered to evaluate patterns of dental attendance.

Results

: DA was found in 90.9% of the pregnant women. The mean DA score of the sample was 12.53 ± 5.33 (range, 5 to 25) and it was significantly higher amongst non-Saudi (13.21 ± 5.24) vs Saudi women (12.15 ± 5.34) (P = .006), those who had negative dental experience (13.99 ± 5.62) vs those without such experience (12.2 ± 5.21) (P < .001), and those with dental pain or discomfort (13.18 ± 5.46) vs without pain or discomfort (11.94 ± 5.14) (P = .001). The study found a significant relationship between DA and reasons for dental attendance before pregnancy (P = .002) and time since the last dental visit (P = .009). Multiple logistic regression analysis showed significantly increased odds (OR, 1.69; 95% CI, 1.25 to 2.27) of experiencing moderate to extreme DA amongst pregnant women who visited the dentist after a year/never visited compared to those who visited in less than a year. Similarly, participants with negative dental experience were significantly more likely to have moderate to extreme DA (OR, 1.49; 95% CI, 1.02 to 2.20) than those without negative experience after adjusting for sociodemographic factors.

Conclusions

: DA was highly prevalent amongst pregnant women, which was significantly associated with negative dental experience, dental pain or discomfort, and reasons for and time since the last dental visit.

Comparison of two minimally invasive restorative techniques in improving the oral health-related quality of life of pregnant women: a six months randomized controlled trial

BACKGROUND

Women tend to delay dental treatment due to misconceptions regarding the safety of dental procedures during pregnancy which may negatively affect their quality of life. Minimally invasive restorative techniques offer alternatives for caries treatment and can improve their oral health-related quality of life (OHRQoL) during this stage.

METHODS

A randomized controlled clinical trial was conducted in 2019 and included 162 pregnant women visiting public family health centers in Alexandria, Egypt, with mild to moderate dental pain due to caries. Participants were randomly assigned into Papacarie-Duo group (n = 82) and ART group (n = 80). The outcome variable was percent change in OHRQoL (oral health impact profile, OHIP-14) after 6 months. T test/Mann Whitney U test were used to compare groups and a multivariable linear regression analysis was conducted to evaluate the factors affecting the outcome variable.

RESULTS

A significant reduction (P < 0.002) was noted in OHIP-14 between baseline and 6 months indicating improvement in OHRQoL in the Papacarie-Duo and ART groups (16.26% and 18.91%, P = 0.120 in bivariate analysis). Multiple linear regression revealed significantly greater reduction in OHIP-14 scores in the Papacarie-Duo than the ART group (regression coefficient = 4.03, 95% confidence interval: 0.652, 7.409, P = 0.020).

CONCLUSION

Minimally invasive restorative techniques, such as ART and chemo-mechanical caries removal using Papacarie- Duo can improve the OHRQoL of pregnant women suffering from mild to moderate pain due to dental caries. Significantly more improvement was noted in the Papacarie-Duo group after adjusting all other variables. Trial registration ID NCT04619264 ( https://clinicaltrials.gov/ ); November 6 2020, retrospective registration. ( https://clinicaltrials.gov/ct2/show/NCT04619264?term=NCT04619264&draw=2&rank=1 ).

The impact of minimally invasive restorative techniques on perception of dental pain among pregnant women: a randomized controlled clinical trial

BACKGROUND

The public dental care sector is striving to fulfill the preventive and restorative needs of Egyptians, including pregnant women, who may not receive timely care due to misconceptions about dental treatment during pregnancy. Because of this, they are likely to suffer dental pain, with higher risk of infection affecting their offsprings.

AIM OF THE STUDY

To compare the effectiveness of chemo-mechanical caries removal using Papacarie-Duo and Atraumatic Restorative Treatment (ART) in reducing dental pain among pregnant women.

MATERIALS AND METHODS

A randomized controlled clinical trial was conducted, in 2019, and included 162 pregnant women visiting family health centers in Alexandria, Egypt, with dental pain due to dental caries not extending to pulp. Patients were randomly assigned to Papacarie-Duo group (n = 82) and ART group (n = 80) after stratification by number of treated surfaces. The outcome variables were reduction in pain assessed using Visual Analogue Scale (VAS), satisfaction with treatment, and time taken for dental caries removal. T test/ Mann Whitney U test were used to compare groups and Freidman test was used to compare change across time.

RESULTS

Pain reduction was significantly greater in the Papacarie-Duo than the ART group (81.55% and 69.43%, P = 0.001). Patients in the Papacarie-Duo group were significantly more satisfied with treatment than those in the ART, immediately after treatment (mean = 9.60 and 8.00, P =  < 0.01) and after 6 months (mean = 9.63 and 8.16, P =  < 0.01). Significantly less excavation time was recorded in the Papacarie-Duo group than in the ART group (mean = 10.38 and 11.56 min, P =  < 0.01).

CONCLUSION

Chemo-mechanical caries removal using Papacarie-Duo is more effective in reducing dental pain, in pregnant women, and is associated with more satisfaction and less excavation time than ART.

Pharmacotherapy during Pregnancy: An Endodontic Perspective

Odontogenic pain affects up to 54.9% of pregnant women^1-3. This pain is often associated with pulpal and/or periapical infections that pose risks to women and their fetus. The American Dental Association in collaboration with the American College of Obstetricians and Gynecologists developed a consensus statement to affirm the importance of timely and appropriate oral health care as a critical component of a healthy pregnancy⁴. However, limited knowledge of endodontic procedure safety and related medication use often result in the avoidance of treatment during pregnancy. This article, a collaborative effort by specialists from endodontics, pediatric dentistry, and obstetrics, reviews the current evidence on the safety of medications commonly used in endodontics including local anesthetics, analgesics, anxiolytics, and antibiotics.

Hyperglycaemia and factors associated with dental caries in immediate postpartum women

Objective: Dental caries and hyperglycaemia share common risk factors. The aim of this study was to identify factors associated with dental caries in women in the immediate postpartum period. It also verified whether women with hyperglycaemia presented more dental caries than those with normal glycaemia.Material and Methods: This cross-sectional study was performed on 297 women recruited from a teaching hospital in Brazil (from October 2011 to November 2012). Dental caries and oral biofilm were evaluated by oral examination. The blood glucose was accessed by Haemoglobin A1c test. Information on socioeconomic characteristics, harmful habits and oral health habits was also gathered.Results: More than half (66%) of the women had carious lesions. Univariate analysis showed no association between hyperglycaemia and dental caries (p = .39). The hierarchical logistic regression model showed that the following variables were associated with dental caries: maternal education level ≤8 years (ORadjusted = 2.40 [CI 1.19-4.82]), previous children (OR_adjusted = 1.81 [CI 1.08-3.03), use of dental floss (OR_adjusted = .48 [CI 0.27-0.86]), and visible plaque index ≥30% (OR_adjusted = 1.83 [CI 1.05-3.20]).Conclusions: These findings call attention to the need to implement effective public policies directed at avoiding tooth decay in pregnancy and in the postpartum period.

Influence of Pregnancy on the Inflammatory Process Following Direct Pulp Capping: a Preliminary Study in Rats

The purpose of this study was to evaluate the inflammatory process following direct pulp capping during pregnancy. This experimental study involved 48 maxillary first molars of female Wistar rats. The procedures were performed in pregnant and non-pregnant animals (n =20 each). Direct pulp capping with mineral trioxide aggregate (MTA) and restoration with a light-cured resin composite was performed in half of exposed pulp specimens. In the other half of specimens, light-cured composite was placed directly on the exposed pulp. In the control groups (n=4 each), no intervention was performed. Animals were euthanized at 3 and 7 days. All sections (three per slide) were viewed under an optical microscope. One previously calibrated pathologist performed descriptive analysis and assigned scores for inflammatory response and tissue organization adjacent to the pulp exposure. The Kappa value for intra-examiner variability was 0.91. At 3 days, in animals treated with MTA, inflammatory infiltrate was absent in non-pregnant animals while mild inflammatory infiltrate was observed in some pregnant animals. The inflammatory response ranged from mild to severe in both groups treated with composite alone. At 7 days, the inflammatory response was more intense in pregnant than in non-pregnant animals treated with MTA; while this difference were not evident in animals treated with composite alone. In conclusion, pregnancy may not influence the inflammatory process following direct pulp capping with light-cured resin composite, which was always harmful to the pulp; while the tissue response after the direct pulp with MTA were more favorable in non-pregnant animals.

Barriers and facilitators to dental care during pregnancy: a systematic review and meta-synthesis of qualitative studies

Some barriers to dental treatment during pregnancy are poorly understood, especially those related to psychosocial factors, which are better explored in qualitative studies. The aim of this systematic review was to explore the barriers and facilitators to dental care during pregnancy through a thematic synthesis of qualitative studies. Qualitative or mixed-methods studies published in English, Portuguese, Spanish and French, from 2000 to 2016, were included. The search strategies were conducted in PubMed, Scopus, Web of Science, LILACS, BBO and CINAHL. To evaluate the quality of the studies, we used the Critical Appraisal Skills Programme tool. Thematic synthesis was performed in order to interpret and summarize the results. From 2,581 screened studies, ten were included in the synthesis. We found 14 analytical themes related to barriers and facilitators to dental care during pregnancy that interacted in complex ways: physiological conditions, low importance of oral health, negative stigma regarding dentistry, fear of/anxiety toward dental treatment, mobility and safety, financial barriers, employment, time constraints, social support, lack of information, health professionals' barriers, family and friends' advice, beliefs and myths about the safety of dental treatment. Myths and beliefs about oral health and dental treatment during pregnancy appear to be the most frequent barriers, both to pregnant women and to dentists or other health professionals. The findings of this review may support new studies, especially to test intervention protocols and to guide effective public policies for the promotion of oral health during pregnancy.

Oral, systemic and socioeconomic factors associated with preterm birth

BACKGROUND

The rates of preterm births have been increasing worldwide. Complications related to preterm births are associated with increased costs of care, and have a direct impact on the health system of the countries. Therefore, it is important to address factors associated with preterm birth in order to provide prevention strategies.

OBJECTIVE

This case-control study investigated oral, systemic, and socioeconomic factors associated with preterm birth in postpartum women. Participants were 279 postpartum women that gave birth to a singleton live-born infant. Cases were women giving birth before 37 completed weeks of gestation (preterm birth). Controls were women giving birth at term (≥37weeks). Data were collected through questionnaires, medical records and intra-oral clinical examinations, which included dental caries registration according to World Health Organization criteria and oral biofilm evaluation through visible plaque index.

RESULTS

Ninety-one women had preterm birth (cases) and 188 women had birth at term (controls), ratio 1:2. Caries lesions were present in 62.3% of the cases and in 62.5% of the controls. The univariate analysis showed no association between dental caries and preterm birth (Odds Ratio=1.08, p=0.90). The multivariate analysis showed that maternal educational level (Odds Ratio=2.56, p=0.01) and arterial hypertension (Odds Ratio=2.32, p=0.01) were associated with prematurity.

CONCLUSION

This study demonstrated that dental caries is frequent in postpartum women, but it does not appear to be associated with preterm birth. Meanwhile, maternal education level and arterial hypertension were associated with prematurity in this population.

Midwives' oral health recommendations for pregnant women, infants and young children: results of a nationwide survey in Germany

BACKGROUND

Studies suggest that poor oral health during pregnancy can lead to perinatal complications, such as low birth weight and preterm delivery as well as poor oral health in children. Aim of this study was to assess the German midwives knowledge about oral health and preventive recommendations for pregnant women, infants and young children.

METHODS

The nationwide online-survey was conducted with use of a self-developed, pretested and validated standardized questionnaire. The German association of midwives (Deutscher Hebammenverband e.V.) informed their members about the survey through email, newsletter, website and association journal (Hebammenforum) (n = 7.500). Data were analyzed using descriptive statistics.

RESULTS

Response rate was 12.6 % (mean age 42.9 ± 9.3 years). The majority of midwives advised pregnant women about periodontal diseases (78.6 %). Of the midwives, 8.4 % mentioned the possible associations between periodontal diseases and perinatal complications. In general, half of the midwives (53.5 %) recommended a dental visit during pregnancy. A total of 65.5 % of midwives advised parents about early childhood caries. The majority of midwives recommended that oral hygiene starts with eruption of the first tooth (60.4 %) and the first dental visit of the child should be at age 2 or 3 years (51.6 %). Midwives recommendations regarding the implementation of oral hygiene and the referral to a dentist during pregnancy and childhood were highly variable.

CONCLUSIONS

To increase oral awareness and to improve the oral health knowledge among midwives and all other health-care professionals, uniform guidelines should be developed in Germany.
