Gingival changes during pregnancy: I. Influence of hormonal variations on clinical and immunological parameters

Immunopathogenesis and immunotherapy of diabetes-associated periodontitis

OBJECTIVES

This paper aims to review the immunopathogenesis of Diabetes-associated periodontitis (DPD) and to propose a description of the research progress of drugs with potential clinical value from an immunotherapeutic perspective.

MATERIALS AND METHODS

A comprehensive literature search was conducted in PubMed, MEDLINE, Embase, Web of Science, Scopus and the Cochrane Library. Inclusion criteria were studies on the association between diabetes and periodontitis using the Boolean operator "AND" for association between diabetes and periodontitis, with no time or language restrictions. Search terms included diabetes mellitus, periodontitis, immunopathogenesis, specific immunity, non-specific immunity, flora, estrogen, pharmacological treatment, immunotherapy.

RESULTS

Alterations in the subgingival flora environment in a hyperglycemic environment elicit an immune response. Overactivity/suppression of nonspecific immune cells and impaired cellular defenses trigger specific immune responses. Epigenetics as well as female hormones also play a role. There is already a small amount of clinical evidence for the role of metronidazole, subantimicrobial doses of doxycycline, minocycline hydrochloride, and metformin in the treatment of DPD. Some preclinical studies have also accumulated experimental evidence for the improved effects of vitamin D3 and other drugs on DPD.

CONCLUSIONS

The development of diabetic periodontitis is immunologically linked to a state of immune imbalance and therefore holds great promise for the use of immunotherapeutic drugs.

CLINICAL SIGNIFICANCE

Immunotherapy with drugs along with periodontal nonsurgical treatment could provide ideas for DPD treatment based on the immunopathogenesis of DPD.

Impact of Hormones and Lifestyle on Oral Health During Pregnancy: A Prospective Observational Regression-Based Study

Background and Objectives: This study explores the impact of hormonal fluctuations during pregnancy and lifestyle factors on stomatognathic system (SS) health. The aim is to determine how pregnancy-related hormonal changes and oral hygiene behaviors affect the onset of stomatognathic issues, such as gingival inflammation (GI) and dental erosion (DE). Materials and Methods: A prospective, observational study was conducted with 100 pregnant women, divided into two groups: Group A (60 women with significant stomatognathic alterations) and Group B (40 women without such alterations). Multiple regression analysis was used to evaluate the influence of hormonal levels, oral hygiene habits, and vomiting episodes on stomatognathic health. Results: Age and socioeconomic status showed no significant association with stomatognathic health (p > 0.05). In contrast, elevated levels of estrogen (p = 0.001) and progesterone (p = 0.003) were significantly linked to the severity of stomatognathic changes. Oral hygiene habits also had a statistically significant impact (p = 0.02), while vomiting frequency was not an important factor (p > 0.05). Conclusions: Hormonal changes during pregnancy, particularly increased estrogen and progesterone levels, are key predictors of stomatognathic health. These findings suggest that while oral hygiene is important, hormonal fluctuations play a dominant role in influencing stomatognathic system (SS) health during pregnancy.

A Survey of Lithuanian Pregnant Women's Knowledge about Periodontal Disease, Its Prevalence and Possible Influence on Pregnancy Outcomes

Background: This study aimed to subjectively assess the changes in the oral health status of pregnant women, to find out their attitudes and knowledge about possible changes in the oral cavity that occurred during pregnancy, and their influence on the outcomes of pregnancy. Methods: 112 pregnant women who visited the Republican Siauliai Hospital during their pregnancy participated in the study. An anonymous self-administered questionnaire was used to conduct the research, surveying their demographic characteristics, oral health changes and habits during pregnancy, and awareness of possible negative pregnancy outcomes. Results: The study involved 112 pregnant women, with 35 in the first trimester, 28 in the second, and 48 in the third trimester. The findings revealed that pregnant women do not take sufficient care of their oral health: more than half of the respondents did not visit an oral care specialist during pregnancy; 22.3% of women reported brushing their teeth only once a day or less; and 35.7% did not clean interdental surfaces at all. Statistically, significantly more urban women believed there is a relationship between maternal oral health and adverse pregnancy outcomes than women living in rural areas (p = 0.013). While significant oral health changes were not observed in the first trimester, more women in the second and third trimesters reported issues such as bleeding gums, swelling, plaque accumulation, tartar, and caries (p < 0.001). Conclusions: The attitude of women towards oral health during pregnancy and their understanding of the possible risks for unfavorable pregnancy outcomes are insufficient. Notably, oral health issues become more prominent in the second and third trimesters, necessitating appropriate oral care to reduce the incidence of oral and dental diseases during pregnancy. This underscores the importance of educational and preventive public health policies focused on oral care for pregnant women, aimed at increasing awareness and promoting practices that safeguard both maternal and fetal health.

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.

Clinical, oral immunological and microbiological shifts during and after pregnancy

OBJECTIVES

Physiological changes and shifts in the oral microbiota composition during pregnancy may affect the maternal immune system. Uncomplicated pregnancy is associated with a T-helper (Th) 2 predominant cytokine regulation (anti-inflammatory), while oral health deterioration during pregnancy is reflected by severe gingival inflammation, a primarily Th1 cytokine phenotype (pro-inflammatory), and oral microbiome alterations. This prospective observational study aimed to evaluate Th cytokine shifts and changes in the oral microbiota composition in saliva of women before and after birth.

MATERIAL AND METHODS

Saliva (n = 96) was collected before and 6 months after birth, and medical, oral health, and periodontal status were assessed. In a multiplex immunoassay, 10 cytokines were simultaneously analyzed and cumulative Th1 and Th2 cytokine levels and Th1/Th2 ratio were calculated for all groups. Putative periodontal pathogens (n = 6) were evaluated by quantitative real-time polymerase chain reaction.

RESULTS

Th2 cytokine levels were significantly lower (p = 0.014) while pro-inflammatory cytokine levels were significantly higher (p < 0.01) during pregnancy than postpartum. Similar Th1 levels were found between the groups (p = 0.143). Th1 and Th2 cytokines positively correlated with periodontal parameters (p < 0.001) and levels of studied bacteria during pregnancy (p < 0.05).

CONCLUSIONS

This study identified a significantly increased Th1/Th2 cytokine ratio during pregnancy and a positive association with putative periodontal pathogens. This immunological and microbiological deregulation in the oral milieu during pregnancy is suggestive of a destructive inflammatory periodontal profile.

CLINICAL RELEVANCE

Understanding altered oral immunological and microbiological regulation patterns during pregnancy may help improve the inflammatory periodontal profile in pregnant women.

Efficacy of Sonic-Powered and Manual Toothbrushes on Plaque-Induced Gingivitis in Pregnant Women: A Randomized Controlled Trial

Hormonal changes and physiological alterations in pregnancy increase the susceptibility of the woman to oral diseases such as plaque-induced gingivitis. In individual oral prophylaxis, effective tooth brushing can reduce gingival inflammation. Therefore, it is necessary to update the scientific evidence to identify which type of toothbrush, manual or sonic-powered, is most effective in reducing the incidence of gingivitis in pregnant women. The aim of this clinical trial is to compare the biofilm control effectiveness of two manual and two sonic toothbrushes in pregnant women. This study is designed as a four-arm, parallel, randomized controlled trial with an allocation ratio of 1:1:1:1. The pregnant woman will be included at 15-18 weeks of amenorrhea and followed for 3 months. The primary outcome will be the change in the incidence of gingival bleeding from a baseline and various follow-up periods of the study. Secondary outcomes measures will be to compare clinical effects of the toothbrushes tested on (i) gingival inflammation, (ii) dental plaque, (iii) gingival attachment and (iv) periodontal pocket; and to assess toothbrush acceptability. Thus, identifying the best device for effective tooth brushing in pregnancy could be helpful in reducing and improving the incidence of gingival inflammation.

The Maternal Microbiome and Gestational Diabetes Mellitus: Cause and Effect

Gestational diabetes mellitus (GDM) is a growing public health concern that affects many pregnancies globally. The condition is associated with adverse maternal and neonatal outcomes including gestational hypertension, preeclampsia, placental abruption, preterm birth, stillbirth, and fetal growth restriction. In the long-term, mothers and children have an increased risk of developing metabolic diseases such as type 2 diabetes and cardiovascular disease. Accumulating evidence suggest that alterations in the maternal microbiome may play a role in the pathogenesis of GDM and adverse pregnancy outcomes. This review describes changes in the maternal microbiome during the physiological adaptations of pregnancy, GDM and adverse maternal and neonatal outcomes. Findings from this review highlight the importance of understanding the link between the maternal microbiome and GDM. Furthermore, new therapeutic approaches to prevent or better manage GDM are discussed. Further research and clinical trials are necessary to fully realize the therapeutic potential of the maternal microbiome and translate these findings into clinical practice.

Evaluation of an advanced oral hygiene regimen on maternity outcomes in a randomized multicenter clinical trial (Oral Hygiene and Maternity Outcomes Multicenter Study)

BACKGROUND

During pregnancy, dental plaque-induced gingivitis prevalence and subsequent risk of periodontal disease increases substantially, as a consequence of both inadequate oral hygiene and changes in sex steroid hormone levels. Although maternal periodontal disease has been associated with adverse pregnancy outcomes, including spontaneous preterm birth, previous clinical trials involving mechanical debridement (eg, scaling and root planing) to remove plaque biofilm have not yielded decreased rates of preterm birth.

OBJECTIVE

We hypothesized that an advanced oral hygiene program, including an antibacterial regimen coupled with a power toothbrush and hygiene instruction, may improve the periodontal milieu and reduce the rate of spontaneous preterm birth. Therefore, we conducted a clinical trial of obstetrical patients with moderate-to-severe gingivitis who were randomized to an advanced oral hygiene program vs usual oral hygiene care, and the primary obstetrical outcome compared between the treatment groups was gestational age at delivery.

STUDY DESIGN

Obstetrical patients with singleton pregnancies between 8 and 24 weeks' gestation were screened by trained dentists at 2 clinical sites for moderate-to-severe gingivitis (>30 intraoral sites with gingival bleeding on probing). Eligible participants were randomized to an advanced oral hygiene regimen, including antibacterial mouth wash, dental floss, antibacterial toothpaste, a power toothbrush, and intensive oral hygiene education vs standard oral home care instructions and regimen. The primary obstetrical outcome assessed was gestational age at delivery. The overall primary (dental) outcomes were gingival index, bleeding sites, and pocket depth (reported elsewhere). Secondary obstetrical outcomes included birthweight and incidence of preterm birth at <37 weeks' gestation. Regression models were utilized and included factors such as treatment group, gestational age at enrollment, preterm birth history, and potential markers of health disparities (ie, education, employment status).

RESULTS

A total of 817 obstetrical patients underwent dental screening at the 2 sites, 789 were identified with moderate-to-severe gingivitis, 746 were randomized, and birth outcomes were available for 613 of the study participants. The gestational age at delivery was 2 days earlier in the control group (P=.040), but the clinical significance of this finding was limited (39.13 vs 38.85 weeks). Overall rates of spontaneous preterm birth <37 weeks and <34 weeks were not statistically different between the 2 treatment groups (7.0% advanced oral hygiene regimen vs 10.3% controls, OR=1.63 (0.90-3.00), P=.11; and 2.3% vs 3.9%, OR=1.88 (0.71-4.98), P=.20, respectively). However, we observed lower rates of spontaneous preterm birth among unemployed participants with less favorable socioeconomic status (4.7% advanced oral hygiene regimen vs 16.0% controls, OR=4.04 (1.34-15.12), P=.01).

CONCLUSION

An advanced oral hygiene program may reduce the risk of spontaneous preterm birth among pregnant patients with moderate-to-severe gingivitis and health disparities. This is the same group that may be at highest risk of poor dental hygiene and preterm birth.

Periodontal Pathogens and Adverse Pregnancy Outcomes: A Narrative Review

Periodontal disease is a multi-microbial infection of the teeth-supporting apparatus that manifests as clinical attachment loss and alveolar bone loss. The association between periodontal disease and systemic diseases has been proposed in the literature owing to the former's chronic state of inflammation, and adverse pregnancy outcomes are no exception. As a result of periodontal pathogen invasion, a series of systemic inflammatory and immunologic events affecting the safety of the fetoplacental unit may unfold. This may be further exaggerated by physiologic hormonal and metabolic fluctuations during pregnancy. This can not only negatively affect the gestation period and consequently cause preterm low weight but also complicate the pregnancy via preeclampsia and gestational diabetes. This narrative review article aims to provide a summary of relevant available evidence pertinent to the relationship between periodontal diseases, associated periodontal pathogens and virulence mechanisms mediated by pro-inflammatory cytokines and prostaglandins, and adverse pregnancy outcomes. Furthermore, this article highlights some of the literature addressing the impact of periodontal therapy interventions and pregnancy outcomes.

Longitudinal Course of Sex Steroids From Pregnancy to Postpartum

CONTEXT

Sex steroids (SS) typically rise during pregnancy and decline after birth, but no consistent reference values exist for these hormonal courses. We aimed to establish an overview of SS secretion patterns during the peripartum and to better understand how SS contribute to maternal and fetal pathologies.

EVIDENCE ACQUISITION

A systematic literature search was conducted in accordance with the PRISMA guidelines using PubMed, Cochrane Library, and PsycINFO. Additionally, we conducted a supplementary manual search of references. Observational studies published in English and assessing estradiol, progesterone, and testosterone over the course of the peripartum in physically healthy female subjects were included, without restrictions on year of publication. Extracted data were analyzed descriptively and visually.

EVIDENCE SYNTHESIS

SS increase progressively during pregnancy, with an extremely wide range of reported concentrations, especially in the third trimester. In fact, reported concentrations varied up to 5000-fold at comparable measurement time points.

CONCLUSIONS

A comprehensive understanding of the influence of SS levels on associated maternal and fetal pathologies is currently hindered by 2 main factors. First, reported SS levels vary widely during the peripartum period. Second, the current state of knowledge on how SS are associated with pathologies in mothers and babies is largely based on correlational studies, and causality thus remains unclear. Consequently, we recommend the development of a systematic reference framework that follows the suggestions presented in this review. This would enable the establishment of SS reference values for a healthy population, resulting in the possibility to draw conclusions about deviations and related pathologies.

How much do pregnant women know about the importance of oral health in pregnancy? Questionnaire-based survey

BACKGROUND

Although pregnancy is a physiological process it causes hormonal changes that can also affect the oral cavity. Pregnancy increases the risk of gum disease inflammation and tooth caries which could affect the health of the developing baby. Proper oral health is crucial both for mother and her babies and is related with mothers' awareness of this connection. The aim of this study was the self-assessment of women's both oral health and oral health literacy as well as mothers' awareness of the connection of oral health and pregnancy.

MATERIAL AND METHODS

In the study anonymous questionnaire was prepared and provided to be filled in by 200 mothers at the age from 19 to 44 y.o. who gave birth in the gynecological clinic. The questionnaire included demographic, and concerning the areas of oral health before and during pregnancy and after the childbirth questions.

RESULTS

Only 20% of the investigated women underwent the oral examination before the pregnancy and the next 38.5% underwent it intentionally when the pregnancy had been confirmed. As much as 24% of women pointed out lack of awareness of the importance of proper oral hygiene during pregnancy. 41.5% of investigated women declared complaints during the pregnancy concerning teeth or gums and 30.5% underwent dental treatment; 68%, brushed their teeth properly-twice a day; 32% of women observed deterioration of oral health state during the pregnancy. The knowledge of the importance of oral health during pregnancy presented by the majority of mothers was relatively proper, which was strongly connected with higher education status and living in big cities. A significant correlation between higher birth weight and more frequent daily tooth brushing was observed. Both higher frequency of problems concerning the oral cavity and dental treatment during pregnancy were significantly related to the younger age of mothers.

CONCLUSIONS

The knowledge of women concerning of oral health on the management of pregnancy and development of fetus is still insufficient. Gynecologists should inquire pregnant women if they have done dental examination, and provide wider education about importance of oral health in pregnancy.

Systemic Profile and Periodontal Condition of Hospitalized Women with High-Risk Pregnancy: A Cross-Sectional Study

INTRODUCTION

The physiological changes in mother-infant pairs during pregnancy increase the susceptibility to a series of infections, including those of the oral cavity. Therefore, the oral and systemic health of pregnant women is related to adverse pregnancy outcomes.

OBJECTIVE

This cross-sectional study aimed to evaluate the systemic profile and periodontal status of women with a high-risk pregnancy.

METHODS

Eighty-nine pregnant women at risk of preterm labor admitted to a hospital in southern Brazil were interviewed and received a periodontal examination. Data related to obstetric complications during pregnancy (pre-eclampsia, infections, medication use, and gestational diabetes) and systemic diseases were collected from medical records. The periodontal parameters of probing pocket depth, bleeding on probing, and clinical attachment level were evaluated. The data were tabulated, and statistical analysis was performed (p < 0.05).

RESULTS

The mean age of participants was 24 years (SD = 5.62). Gingival bleeding was recorded in 91% of the participants. The prevalence of gingivitis was 31.46%, and periodontitis was 29.21%. No association between systemic conditions and periodontal disease was observed.

CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Periodontal inflammation was not associated with the systemic profile during pregnancy. However, women with high-risk pregnancies showed higher levels of gingival inflammation, emphasizing the importance of dental care during pregnancy.

Isobaric tags for relative and absolute quantification (iTRAQ)-based quantitative analysis of the salivary proteome during healthy pregnancy and pregnancy gingivitis

AIM

The present study aimed to investigate the salivary proteome profiles of pregnant women with gingivitis (PG) or without gingivitis (HP) and non-pregnant healthy controls (HC) by employing iTRAQ-based proteomics.

MATERIALS AND METHODS

Saliva samples were collected from 30 Chinese women comprising 10 subjects in each of the three groups (PG, HP, and HC). The samples were subjected to iTRAQ-based proteomics analysis, and ELISA was performed to validate the results. The subsequent observations were validated in a cohort of 48 subjects.

RESULTS

Pathways associated with neutrophil-mediated immune response and antioxidant defence mechanism were significantly higher in PG than HC. The abundance of salivary cystatins (S, SA, and SN) and antimicrobials were significantly decreased in PG and HP, while cystatin C and D were additionally decreased in PG. Cystatin C was mapped to all the major catabolic pathways and was the most re-wired protein in pregnancy gingivitis. Further validation demonstrated cystatin C to be significantly lower in PG than HC.

CONCLUSIONS

While the decrease in levels of salivary cystatins and antimicrobial proteins may predispose healthy pregnant women to pregnancy gingivitis, it may cause persistence of inflammation in pregnant women with gingivitis.

Associations between dental care approachability and dental attendance among women pregnant with an Indigenous child: a cross-sectional study

BACKGROUND

Oral health during pregnancy is vital for both mother and child. Indigenous Australians face many barriers in accessing dental care. Service approachability is one of the key domains in accessing health services. There is little empirical evidence of the association between service approachability and dental care attendance or oral health outcome. The aim of this study is to examine the relationship between dental service approachability on dental care attendance and self-reported gum disease among South Australian women pregnant with an Aboriginal child.

METHODS

Four hundred and twenty-seven women pregnant with an Aboriginal child completed questionnaires in both metropolitan and regional health settings in South Australia in 2011. Four variables related to approachability of dental services: (1) perception of need; (2) service-related health literacy; (3) oral health beliefs and; (4) trust and expectation of dental service. The association between service approachability-related factors, dental utilisation and self-reported gum disease during pregnancy were assessed using Generalised Poisson regression models, after adjusting for age, remoteness, employment status and education. Estimates were presented as adjusted prevalence ratios (APR).

RESULTS

Most participants (85.8%) reported a need for dental care, had positive oral health beliefs (88.3%) and had expectations towards dental care (86.2%). Dental service utilisation during pregnancy was low (35.7%). Many participants (78.0%) expressed knowing what to do if they needed dental care, while most (39.8%) doubted that dental care would be available the next day. Poor health service literacy was identified as a risk factor for non-optimal dental attendance (APR = 0.86, 95%CI 0.74-0.99). Perceived need for dental care was positively associated with self-reported gum disease (APR = 1.24, 95%CI 1.06-1.45).

CONCLUSION

Inability to navigate the dental care system was a risk factor for poor dental attendance among South Australian women pregnant with an Aboriginal child. Perceived need for dental care was associated with gum disease.

Oral Microbiota: A Major Player in the Diagnosis of Systemic Diseases

The oral cavity is host to a complex and diverse microbiota community which plays an important role in health and disease. Major oral infections, i.e., caries and periodontal diseases, are both responsible for and induced by oral microbiota dysbiosis. This dysbiosis is known to have an impact on other chronic systemic diseases, whether triggering or aggravating them, making the oral microbiota a novel target in diagnosing, following, and treating systemic diseases. In this review, we summarize the major roles that oral microbiota can play in systemic disease development and aggravation and also how novel tools can help investigate this complex ecosystem. Finally, we describe new therapeutic approaches based on oral bacterial recolonization or host modulation therapies. Collaboration in diagnosis and treatment between oral specialists and general health specialists is of key importance in bridging oral and systemic health and disease and improving patients' wellbeing.

Salivary Proteomic Profiling Identifies Role of Neutrophil Extracellular Traps Formation in Pregnancy Gingivitis

Pregnancy gingivitis peaks during mid-pregnancy and resolves transiently towards the postpartum period. However, the role of maternal immune response in orchestrating gingival inflammation has not yet been fully understood. Hence, in this study, we examined the salivary protein profile during the three trimesters of pregnancy, in context to pregnancy gingivitis, employing iTRAQ-based quantitative proteomics. Unstimulated saliva was collected from 10 subjects in each trimester of pregnancy and postpartum period. Samples were analysed using iTRAQ analysis and ELISA and SEM was performed to validate results. Neutrophil mediated immune response was overrepresented in all three trimesters of pregnancy, despite the decrease in phagocytic responses during the second and third trimesters. ELISA showed a significantly higher Neutrophil Extracellular Traps (NETs) formation in the third trimester of pregnancy coinciding with the resolution of pregnancy gingivitis. The NETs-associated proteins (neutrophil elastase and myeloperoxidase) showed a positive correlation with estrogen hormones, which was also highest during the third trimester. Sex hormone-driven NETs formation could be the mainstay of defence that contributes to the remission of pregnancy gingivitis. This study has provided a new insight into the role of immune-modulation in pregnancy gingivitis, which will aid development of new therapeutics for managing pregnancy gingivitis in future.

[Treatment strategy for pregnancy epulis]

Pregnancy epulis is a tumor-like lesion with high prevalence in China. The local lesion, the general condition of the pregnant patient, and the complications during treatment should be taken into consideration when making a treatment plan for pregnancy epulis. In this study, three representative pregnancy epulis cases were presented, and related studies at home and aboard were reviewed to summarize the etiology, differential diagnosis, treatment, and prevention of pregnancy epulis and share the clinical experience in the treatment of pregnancy epulis.

Oral Status in Pregnant Women from Post-Industrial Areas of Upper Silesia in Reference to Occurrence of: Preterm Labors, Low Birth Weight and Type of Labor

Increased levels of steroid hormones, action of local irritants and the lack of proper hygiene measures are of great importance in the development of dental caries, gingivitis and inflammation of the periodontal area in pregnant women. The aim of the study was to evaluate the state of oral hygiene and the periodontal area is such a population and assess the effectiveness of performed hygiene treatments and analyse changes in hygiene habits after oral hygiene instructions. The study was performed in two parts on a group of 50 pregnant women. The first part took place between the 14th and 17th week of pregnancy. The control study was conducted between the 27th and 30th week of pregnancy. Patients were subjected to a dental examination. Poor oral hygiene was observed among the examined patients. After the first examination, oral hygiene instruction was provided to 25 randomly selected pregnant patients. The effect of periodontal diseases on the time of labor was observed. Oral hygiene instructions significantly affected the state of the periodontal area of pregnant women for whom it was performed. It was confirmed that the advancement of pregnancy influences deterioration of the periodontium and also term of childbirth. Undoubtedly, pregnant women receive insufficient dental care. Priority should be given to dental care education of for pregnant women and alleviating the impact of oral diseases on the organism of a pregnant woman.

Effectiveness of a family-centered behavioral and educational counselling approach to improve periodontal health of pregnant women: a randomized controlled trial

BACKGROUND

Poor oral hygiene and high hormone levels during pregnancy can lead to a deterioration in periodontal health. This study assessed the effectiveness of a family-centered behavioral and educational counselling program on improving the periodontal health of women during pregnancy and postpartum.

METHODS

A randomized controlled trial was conducted among pregnant women (10th-22nd gestational week) and their husbands. Participating families were randomized into test and control groups. Intervention in the test group included explanation of oral health education (OHE) pamphlets, oral hygiene instruction, individualized feedback, and proposed solutions to overcome barriers in self-care. Reinforcements were implemented in the 3rd trimester of pregnancy and six months postpartum. In the control group, only OHE pamphlets were distributed. The assessed outcomes were bleeding on probing (BOP), periodontal pocket (Poc), loss of clinical attachment (LoA), and Visible Plaque Index (VPI). The data collection was carried out at baseline (T₀), in the 32nd gestational week (T₁), and 12 months postpartum (T₂).

RESULTS

Altogether 589 pregnant women were recruited, and 369 attended all three visits (test:188; control:181). In the test group, the mean VPI score at T₀ was 0.19, which decreased to 0.14 at T₁ and 0.15 at T₂. In the control group, the mean VPI decreased from 0.19 at T₀ to 0.16 at T₁, but increased to 0.22 at T₂. A main effect of time and intervention and an interaction between time and intervention were detected (all p < 0.05), indicating that the intervention effect differed between T₁ and T₂. The test group showed a significantly greater decrease over time than the control group did. Similarly, the mean BOP% decreased more significantly over time in the test group (T₀:57%, T₁:46%, T₂:35%) than in the control group (T₀:58%, T₁:52%, T₂:46%). For Poc and LoA, there were improvements in both study groups at 12 months postpartum, compared with during pregnancy (p < 0.001).

CONCLUSIONS

Providing family-centered, behavioral, and educational counselling to pregnant women at an early stage of pregnancy and with reinforcements can improve their oral hygiene and reduce gingival inflammation. The effect can be sustained over an extended period and is greater than that of distributing oral health leaflets alone.

Early pregnancy levels of gingival crevicular fluid matrix metalloproteinases-8 and -9 are associated with the severity of periodontitis and the development of gestational diabetes mellitus

BACKGROUND

Gestational diabetes mellitus (GDM) is increasing worldwide and women with a history of GDM are at risk of developing type 2 diabetes which is a risk factor for periodontitis. The aim of this study was to explore the association between the concentrations of matrix metalloproteinase (MMP)-8 and -9 in gingival crevicular fluid (GCF) during early pregnancy with the periodontal diagnosis and the risk of GDM development.

METHODS

A prospective cohort study, including 314 women, enrolled at 11 to 14 weeks of pregnancy was conducted. A complete maternal/obstetric and periodontal exam was performed, and GCF samples were obtained for the MMP-8 and -9 determination by Multiplex Elisa Assays. Mann-Whitney test; Spearman's correlation and log-binomial regression model estimated the association between MMPs concentration in GCF and GDM.

RESULTS

Fourteen percent of the pregnancies were diagnosed with GDM. An increase in the concentration of MMP-8 and -9 in women with periodontitis stage III and IV compared to periodontitis stage I was observed (99.31 ng/mL [IQR: 85.32] versus 71.95 ng/mL [IQR: 54.04], and 262.4 ng/mL [IQR: 312.55] versus 114.1 ng/mL [IQR: 184.94], respectively). Women who developed GDM showed increased concentrations of MMP-8 and -9 in GCF since the beginning of pregnancy (P = 0.0381; P = 0.0302, respectively). MMP-8 concentration in GCF was associated with GDM (RR: 1.19; P = 0.045; CI 95% 1.00 to 1.40; and RR: 1.20; P = 0.063; CI 95% 0.99 to 1.45 in the adjusted model).

CONCLUSION(S)

GCF concentrations of MMP-8 and -9 at early of pregnancy are increased in women with severe periodontitis and associated with the GDM development.

Hormone-related events and periodontitis in women

AIM

While the short-term effects of hormonal events on gingival inflammation have been well described, long-term effects on the periodontium have received less attention. The aim of this cross-sectional population-based study was to evaluate the association between hormone-related events and periodontitis in a representative sample of the postmenopausal women of South Korea.

MATERIALS AND METHODS

A total of 10,273 postmenopausal women representative of 6.1 million of Koreans were examined. Periodontitis and severe periodontitis were defined according to the Community Periodontal Index (CPI ≧ 3 and CPI = 4, respectively). Univariate and multivariate regression analyses using 3 different models were applied controlling for age, smoking, marital status, educational level, income, BMI, hypertension, stress and frequency of toothbrushing.

RESULTS

Severe periodontitis was directly associated with a longer reproductive life (p-trend = .027) and with a longer duration of breastfeeding (48-72 vs. 1-17 months: OR = 1.49; 95% CI: 1.01-2.21). Conversely, early menopausal age (<46 vs. 49-50 years: OR = 0.74; 95% CI: 0.56-0.97), history of artificial menopause (OR = 0.72; 95% CI: 0.53-0.97), having had more than 6 pregnancies (vs. 4: OR = 0.73; 95% CI: 0.55-0.97), having had more than three abortions (vs. 0: OR = 0.51; 95% CI: 0.28-0.93) and having had the first birth age >26 years (vs. <21 years: OR = 0.71; 95% CI: 0.52-0.97) were inversely associated with severe periodontitis.

CONCLUSIONS

In this large nationally representative population, severe periodontitis was related to menopausal age, reproductive life length, number of pregnancies/abortions, first birth age and breastfeeding duration, while it was not to oral contraceptive and hormone replacement therapy usages.

Correlation of periodontal and microbiological evaluations, with serum levels of estradiol and progesterone, during different trimesters of gestation

Our purpouse was to identify quantitatively and qualitatively the subgingival flora in different gestational trimesters, compared to non-pregnant women; evaluating the correlations between epidemiological characteristics, clinical diagnosis, microbiological findings and levels of estradiol and progesterone. 52 pregnant women divided into 3 groups, according to the gestational trimester and 15 non-pregnant patients, without hormonal contraceptives, were evaluated. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) were evaluated. Subgingival biofilm samples were processed by the qPCR technique and the serum levels of estradiol and progesterone quantified by chemiluminescence. Clinical diagnosis during gestation was correlated with the total bacterial count. A higher prevalence of Tannerella forsythia (Tf) was identified in first trimester of pregnancy and this periodontopathogen was correlated with the diagnosis of gingivitis among pregnant women. Porphyromonas gingivalis (Pg) showed a positive correlation with progesterone levels in the first trimester. High prevalence of periodontopathogens was noticed in this population. Clinical diagnosis in gestation was positively correlated with the total amount of bacteria, without influence of the hormonal levels or the epidemiological factors evaluated. The presence of Tf favored occurrence of gingivitis during pregnancy and the progesterone levels in the first trimester enhanced the growth of Pg.

Knowledge and Attitude of Midwifery Students on Oral Health Care

Midwifery students can have an important role in transferring oral health care information to expecting mothers. The aim of this study was to assess the effect of an educational intervention on knowledge and attitudes of midwifery students on oral health in pregnancy. Study population consisted of 60 midwifery students in a Midwifery School in Iran who were randomly allocated into case and control groups. Self-administered questionnaires were distributed before, immediately after the intervention and also three months later. The validity and reliability of the questionnaire was confirmed at the beginning. Mean total pre-test knowledge scores from total 10 in the interventional and control groups were 4.63 ± 0.25 (Standard Error, SE) and 4.79 ± 0.31 (SE) respectively. After three months scores reached to 8.87 ± 0.15 (SE) in the interventional and 5.57 ± 0.29 (SE) in the control groups. Mean attitude pre-test scores in the interventional group was 27.23 ± 0.75 (SE) and after the intervention reached to 31.13 ± 0.25 (SE). Lecture-based educational intervention improved the knowledge and attitudes of midwifery students on oral health care in pregnancy. Incorporating courses on oral health in pregnancy into the curricula of midwifery programs can be effective in promoting oral health care in pregnant women.

Coronally advanced flap with and without platelet-rich fibrin in the treatment of multiple adjacent recession defects: A randomized controlled split-mouth trial

Background:

The objective of our study was to evaluate and compare the effectiveness of coronally advanced flap (CAF) with or without the use of platelet-rich fibrin (PRF) membrane in the treatment of multiple adjacent recession defects (MARD) clinically and by cone-beam computed tomography (CBCT).

Materials and Methods:

Twenty healthy patients having 75 MARD were allocated randomly to CAF with orthodontic button group (CAFB) or CAFB + PRF membrane group (CAFB + PRF). Clinical parameters such as gingival recession depth (GRD), probing depth (PD), and keratinized tissue width (KTW) were calculated at baseline, 3 months, and 6 months. The distance from the facial alveolar crest of bone to gingival margin bone and gingival thickness (GT) at three different points were assessed by CBCT at baseline and 6-month postsurgery. Esthetic outcome and postoperative discomfort were evaluated using root coverage esthetic score and visual analog scale, respectively.

Results:

Percent root coverage achieved in CAFB category was 93.17% ± 13.23% and that in CAFB + PRF group was 95.68% ± 10.13% at 6 months, with no notable difference. Similarly, no difference was found in either group in GRD reduction, PD, and CAL postoperatively. Use of PRF resulted in statistically highly significant (P < 0.001) increased GT at 6 months’ time point as compared to participants treated with CAF without PRF, which indicates clinical and esthetic benefits achieved through the procedure.

Conclusions:

CAFB can be used successfully to treat MARD with predictable outcome. Additional benefit in terms of gain in KTW and GT can be achieved when PRF membrane is used as an adjunct.

Porphyromonas gingivalis induces exacerbated periodontal disease during pregnancy

Although pregnant women are prone to gingival inflammation, its mechanism remains unclear. Animal models are ideal for investigating immunological mechanisms in the periodontal disease. A murine model for ligature-induced periodontal disease has been modified and utilized to determine the susceptibility to periodontal inflammation and tissue damage in pregnant mice. Expression of different inflammatory mediators in the gingivae was determined by quantitative real-time PCR (qPCR). Inflammatory bone loss was determined by measuring the distance from the cementoenamel junction to the alveolar bone crest (CEJ-ABC). Oral bacterial number was determined by the CFU (Colony Forming Units) count from anaerobic culture of oral swabs. In our experiments, ligation itself did not cause higher gingival inflammation and bone loss in pregnant mice than non-pregnant mice, while ligation combined with P. gingivalis infection led to increased gingival inflammation and periodontal bone loss, accompanied by lower gingival expression of anti-inflammatory cytokines in pregnant mice. Our results indicated that P. gingivalis infection was important in inducing more severe periodontal diseases during pregnancy, which might be attributed to the down-regulated anti-inflammatory mechanisms, but not be associated with higher oral bacterial burden.

Effect of non-surgical periodontal therapy on the degree of gingival inflammation and stress markers related to pregnancy

OBJECTIVES

The purpose of this study was to determine the impact of nonsurgical periodontal therapy considering the salivary stress-related hormone and cytokine levels in the gingival crevicular fluid (GCF) on pregnant and nonpregnant women.

MATERIAL AND METHODS

Thirty non-pregnant (control group) and 30 pregnant women (test group) that met the study inclusion criteria were chosen. Only participants with gingivitis were included. Clinical data and samples of GCF and saliva were collected at baseline and after periodontal therapy. The levels of interleukin-1 beta (Κ-1β) and IL-10, and concentration of salivary chromogranin A (CgA) hormone were analyzed by enzyme-linked immunosorbent assay (ELISA). The repeated measures analysis of variance was used for intragroup and intergroup analyses.

RESULTS

A major decrease in the gingival inflammation was observed in both groups after periodontal therapy (p<0.05). Periodontal treatment decreased the level of IL-1β in GCF (p<0.05) in control group, but no statistical difference was determined for GCF IL-1β in the test group. However, after periodontal therapy, the CgA hormone concentration was reduced in both groups (p<0.05). However, there was no difference in salivary CgA concentration, GCF IL-10 levels, and perceived stress scale (PSS)-10 between the groups (p>0.05).

CONCLUSIONS

Within the limitations of this study, periodontal therapy significantly improved the periodontal status and stress level. In addition, the severity of the gingival inflammation during pregnancy was related to stress. However, further studies will be needed to substantiate these early findings.

Pregnancy-induced periodontal inflammation: Influence of salivary cytokines and antimicrobial proteins

The aim of this study was to evaluate the association between pregnancy-induced periodontal inflammation and levels of some salivary cytokines and antimicrobial proteins (AMPs). The study was a cohort longitudinal study that included pregnant women attending a secondary health facility. Consented participants had oral examination and saliva sampling during pregnancy and post-partum (three months after pregnancy). Saliva samples were used for the analysis of cytokines (TNF-α, IFN-gamma and IL-1β) and AMPs (Lactoferin, Lysozyme, and β defensin-1) using ELISA. Data are presented as median with interquartile range and compared using related sample Wilcoxon signed rank test. Correlations between levels of the salivary factors and indices of periodontal inflammation were determined using Spearman’s correlation test. Salivary flow rate, pH, levels of salivary IL-1β and IFN-gamma were significantly lower; while gingival index, periodontal index and level of salivary TNF-α were significantly higher during pregnancy compared with postpartum period. However, salivary lactoferin, lysozyme and β defensin-1 did not show significant difference comparing during pregnancy and postpartum period. Level of salivary IFN-gamma showed negative correlation with gingival index while level of salivary TNF-α showed positive correlation with gingival and periodontal indices. Lower levels of salivary IL-1β and IFN-gamma along with higher TNF-α concentration during pregnancy suggest their contributions to the pathophysiology of pregnancy-induced periodontal inflammation.

Pregnancy, parity and periodontal disease

Many women believe that their dental condition deteriorated during pregnancy or as a result of having children. Epidemiological studies have reported an association between higher parity and tooth loss, and higher parity and periodontal attachment loss. Several possible explanations for this association exist. First, hormonal changes during pregnancy affect the immune response to bacterial plaque and drive vascular and gingival changes that may contribute to heightened gingival inflammation. These changes are transient, without irreversible loss of periodontal attachment, and post-partum resolution can be expected for most women. For women with destructive periodontal disease, the effects of pregnancy and parity are unclear. Second, it is also plausible that parity and socioeconomic position (SEP) have shared risk factors, increasing the incidence of disease or influencing its management. Education, one aspect of SEP, is an important determining factor for women's fertility rate, with a gradient of fewer children with higher educational attainment. Higher levels of education are also favourably associated with behaviours conducive to oral health, and a lower incidence of damaging health behaviours. Thus, the potential for confounding is considerable. This review examines the literature on the association between pregnancy, parity and periodontal health, and explores sociobehavioural mechanisms for the observed association.

Biological Effects of Medicinal Plants on Induced Periodontitis: A Systematic Review

Objective. The aim of this systematic review was to investigate the advances in the study of medicinal plants and their biologic effects on periodontitis in animal models. Study Design. A systematic search was conducted by three independent researchers, who screened articles published up to March/2016, to identify the studies that contained sufficient and clear information on the association of the medicinal plants and periodontitis in murine models. The searches were performed using PubMed, Cochrane, and Science Direct databases. Results. After a critical analysis of titles and abstracts, 30 studies were finally eligible for analysis. The studies presented a great diversity of the experiment designed regarding the methods of induced periodontitis and the evaluation of the medicinal plants efficacy. None of the studies described the possible toxic effects associated with the administration of the plant material to animals and whether they could prevent damage to organs caused by systemic effect of induced periodontitis. Gel-based formulations containing plant substances are seen as an interesting strategy to treat periodontitis. Conclusions. In this systematic review, the state-of-the-art knowledge on the medicinal plants and the induced periodontitis was critically evaluated and discussed from the experiment designed to the possible clinical application.

Salivary antimicrobial defensins in pregnancy

AIM

Susceptibility to and severity of gingival inflammation are enhanced during pregnancy; however, regulation of oral innate immune response, including antimicrobial peptides, during pregnancy is still unknown. We analysed salivary levels of human beta-defensin (hBD)-1, -2, -3, and human neutrophil peptide (HNP)-1 in pregnant women, and related those to their periodontal status.

MATERIAL AND METHODS

In this cohort study, 30 generally healthy, non-smoking Caucasian women without periodontitis were followed at three time points during pregnancy and twice post-partum. The non-pregnant group consisted of 24 women, who were examined three times at the following months. At each visit, periodontal status was recorded and stimulated saliva samples were collected. Salivary estradiol, progesterone, and defensin concentrations were measured by ELISA assays.

RESULTS

After adjusting for visible plaque and gingival bleeding, reduced salivary concentrations of hBD-1, hBD-2, and HNP-1 were found especially during the third trimester, whereas hBD-3 concentrations did not change during pregnancy and post-partum visits. Weak associations were observed between salivary defensin and hormone concentrations and clinical parameters.

CONCLUSION

There seems to be an independent regulation cascade for each antimicrobial defensin in the oral cavity during pregnancy, despite of the similarities between these antimicrobial peptides.

Sex Hormones Enhance Gingival Inflammation without Affecting IL-1β and TNF-α in Periodontally Healthy Women during Pregnancy

Hormones (progesterone and estradiol) change greatly during pregnancy; however, the mechanism of hormonal changes on gingival inflammation is still unclear. This study is to evaluate the effects of hormonal changes during pregnancy on gingival inflammation and interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in gingival crevicular fluid (GCF). 30 periodontally healthy pregnant women were evaluated in the first, second, and third trimesters. 20 periodontally healthy nonpregnant women were evaluated twice (once per subsequent month). Clinical parameters including probing pocket depth (PPD), bleeding index (BI), gingival index (GI), clinical attachment level (CAL), and plaque index (PLI) were recorded. GCF levels of IL-1β and TNF-α and serum levels of progesterone and estradiol were measured. From the data, despite low PLI, BI and GI increased significantly during pregnancy; however, no significant changes in PLI, CAL, IL-1β, or TNF-α GCF levels were observed. Although IL-1β, not TNF-α, was higher in pregnant group than in nonpregnant group, they showed no correlation with serum hormone levels during pregnancy. GI and BI showed significant positive correlation with serum hormone levels during pregnancy. This study suggests that sex hormone increase during pregnancy might have an effect on inflammatory status of gingiva, independent of IL-1β and TNF-α in GCF.

Periodontal Condition and Treatment Needs of Some Pregnant Women in Ibadan, Nigeria

Background:

Periodontal diseases had been reported to be worse in the presence of hormonal imbalance as seen during pregnancy, which if that is the case, should resolve following childbirth when the hormonal level of the women should have reverted to normal.

Subjects and methods

Periodontal health of 345 pregnant women was assessed once during pregnancy and at 14^th week following their childbirth. The clinical variant of community periodontal index of treatment needs probe was used in the assessment.

Results:

During pregnancy, 167/345 (48.4%) of the women had deep pockets, 178/345 (51.6%) had shallow pockets. After childbirth, 5/345 (1.5%) had healthy periodontium, 25/345 (7.2%) had calculus and 7/345 (2.0%) had deep pockets. All of the respondents required oral hygiene instructions (OHI) and prophylaxis and 167/345 (48.4%) required complex treatment during pregnancy. After childbirth, 340/345 (98.5%) of the women required OHI and prophylaxis. Despite the great need for dental treatment among the respondents, majority never sought any treatment as 308/345 (89.3%) of the respondents had never visited a dentist before the study.

Conclusion:

The fact that the deep pocket reduced drastically following childbirth shows that it was not a true pocket. The high unmet treatment needs among the respondents require a concerted effort from dentists and policy makers in order to enlighten the women, especially those of child bearing age concerning the need for preventive dental visitation.

Relationship between gingival inflammation and pregnancy

An increase in the prevalence and severity of gingival inflammation during pregnancy has been reported since the 1960s. Though the etiology is not fully known, it is believed that increasing plasma sex steroid hormone levels during pregnancy have a dramatic effect on the periodontium. Current works of research have shown that estrogen and progesterone increasing during pregnancy are supposed to be responsible for gingivitis progression. This review is focused not only on epidemiological studies, but also on the effects of progesterone and estrogen on the change of subgingival microbiota and immunologic physiological mediators in periodontal tissue (gingiva and periodontal ligament), which provides current information about the effects of pregnancy on gingival inflammation.

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.

Giant granuloma gravidarium of the oral cavity

Oral health is affected by hormonal changes during pregnancy but is usually neglected by both the obstetrician and the patient during follow-up visits. Gingival enlargement is one of the most common oral lesions seen during pregnancy. Rarely, gingival enlargement can be very big, significantly affecting maternal nutrition and impairing haemodynamic status. A giant granuloma gravidarium and appropriate management strategies are discussed. Patients must be encouraged to undergo regular dental check-ups during pregnancy. Simple oral hygiene measures are highly effective in mitigating most oral lesions of pregnancy.

Literacy, pregnancy and potential oral health changes: the Internet and readability levels

The purpose of this study is to evaluate the readability level and content of articles concerning pregnancy and the periodontium which are presented on internet websites. Websites were selected from Google, Yahoo, and Bing. The sites which were excluded were: commercial sites; blogs; dental office sites; sites with articles having fewer than 20 sentences; duplicated search results; and non-secure sites (N = 137). The grade level was determined from the SMOG reading index. Content was scored for specific pregnancy related periodontal content. The mean reading level was 8th grade. The mean number of words with 3 or more syllables in 20 sentences was 38.90. Articles written below the 8th grade level were more likely to recommend brushing twice a day and using a soft-bristled brush. Articles at or above the 8th grade level were more likely to discuss preterm birth and periodontal disease. One article from a national dental organization and 3 from government sites were returned from the searches. Internet articles are written across the literary spectrum. Dental organizations were not adequately represented. Many advertisements, .coms, and non-secure sites pose challenges in seeking health information. Although the internet is a useful tool, practitioners need to provide trustworthy, useful information during clinical visits and encourage national and state medical and dental organizations to provide content in response to search terms that would be typically used.

Oral health education and therapy reduces gingivitis during pregnancy

BACKGROUND

Pregnant women demonstrate increases in gingivitis despite similar plaque levels to non-pregnant counterparts.

AIM

To evaluate an intensive protocol aimed at reducing gingivitis in pregnant women and provide pilot data for large-scale randomized controlled trials investigating oral hygiene measures to reduce pregnancy gingivitis and alter maternity outcomes.

MATERIALS AND METHODS

One hundred and twenty participants between 16 and 24 weeks gestation with Gingival Index (GI) scores ≥2 at ≥50% of tooth sites were enrolled. Plaque index (PI), gingival inflammation (GI), probing depth (PD), and clinical attachment levels (CAL) were recorded at baseline and 8 weeks. Dental prophylaxis was performed at baseline and oral hygiene instructions at baseline, 4 and 8 weeks. Pregnancy outcomes were recorded at parturition. Mixed-model analysis of variance was used to compare clinical measurements at baseline and 8 weeks.

RESULTS

Statistically significant reductions in PI, GI, PD, and CAL occurred over the study period. Mean whole mouth PI and GI scores decreased approximately 50% and the percentage of sites with PI and GI ≥2 decreased from 40% to 17% and 53% to 21.8%, respectively. Mean decreases in whole mouth PD and CAL of 0.45 and 0.24 mm, respectively, were seen.

CONCLUSIONS

Intensive oral hygiene regimen decreased gingivitis in pregnant patients.
