Consideration of hormonal changes for orthodontic treatment during pregnancy and lactation - a review

Hormonal changes in pregnant and lactating women significantly affect bone metabolism and overall stress levels, positioning them as a unique group within the orthodontic population. Fluctuations in estrogen, progesterone, prolactin, and other hormones are closely linked to bone remodeling and the periodontal tissue's response to inflammation caused by dental plaque. Hormones such as thyrotropin, leptin, and melatonin also play crucial roles in pregnancy and bone remodeling, with potential implications for orthodontic tooth movement. Additionally, adverse personal behaviors and changes in dietary habits worsen periodontal conditions and complicate periodontal maintenance during orthodontic treatment. Notably, applying orthodontic force during pregnancy and lactation may trigger stress responses in the endocrine system, altering hormone levels. However, these changes do not appear to adversely affect the mother or fetus. This review comprehensively examines the interaction between hormone levels and orthodontic tooth movement in pregnant and lactating women, offering insights to guide clinical practice.

An Assessment of Oral Health Training in Obstetrical Care in Massachusetts

PURPOSE

Oral health (OH) has significant effects on pregnancy and infant outcomes. This study assesses the perspectives of obstetrical clinicians about OH education and promotion.

METHODS

A fifteen-item survey was developed and circulated to obstetrics and gynecology (OBGYN) and family medicine (FM) physicians, and other prenatal health clinicians in Massachusetts (MA). Additionally, eight physicians were purposively sampled for in-depth interviews to discuss their experience with prenatal OH training and practice. Bivariate relationships between outcome variables from the survey (e.g., previous OH training, awareness of OH guidelines, asking about OH during prenatal visits) were analyzed along with coding and analysis of the qualitative interview data.

RESULTS

The majority (77%) of the 86 survey respondents did not feel well-trained in OH. We found significant associations between being well-trained in OH and: (1) awareness of state guidelines (X2 = 11.85, p < 0.001); (2) asking about OH during prenatal visits (X2 = 9.21, p = 0.002); and (3) routinely referring patients for dental care (X2 = 15.35, p < 0.001). Lack of access to dental insurance and dental professionals were found to be major perceived barriers to care. Responses from the interviews reinforced these findings.

Oral health knowledge, literacy and behavior of pregnant women: a qualitative study in a northeastern province of Thailand

BACKGROUND

Pregnancy is a unique period of women's lives, and oral health is an important public health indicator during this period. Pregnant women have increased vulnerability to oral health problems. The study aimed to describe oral health knowledge, literacy and behavior of pregnant women in a northeastern province of Thailand.

METHODS

A descriptive study was used. Twenty pregnant women who attended antenatal care clinics of eight public hospitals in the province were recruited by use of purposive sampling. They participated voluntarily in individual interview. The Health Belief Model was used as conception framework. All data were transcribed and subjected to content analysis.

RESULTS

Five categories emerged: Misbelief and lack of knowledge, Oral health problems and dental care seeking, Oral health information from different persons, Self-care management of oral health, and Fear of and anxiety towards dental treatment. The findings showed that low knowledge of need for treatment, little importance to oral health and low priority of dental needs affect the demand for dental care. Fear of and anxiety towards dental treatment were the results of negative past experiences of neglecting dental care. Some women perceived health benefits of practicing self-care of oral health during pregnancy.

CONCLUSION

The findings help to better understand the oral health issues of pregnant women and provide baseline information for oral health promotion. Such promotion and culturally appropriate care should be integrated in maternal health education classes.

The effect of training intervention based on the theory of planned behavior on oral and dental health behaviors in pregnant women

BACKGROUND

Pregnancy is a transient physiological condition that causes adverse oral and dental consequences. The present study aimed to determine the effect of a training intervention based on the theory of planned behavior on oral and dental behaviors in pregnant women.

METHODS

This quasi-experimental study was conducted on 140 pregnant women (70 in the intervention group and 70 in the control group) supported by comprehensive health centers on the outskirts of Shiraz, Iran, in 2019-2020. The sampling was performed in each center by a simple random method. The tool included a demographic characteristics questionnaire, a questionnaire based on the theory of planned behavior, a self-care behavior questionnaire, and checklists for recording DMFT(Decayed, Missing due to caries, and Filled Teeth(DMFT)) and dental plaque indices. The questionnaires were completed before and 3 months after the intervention by both groups. The intervention group received six 50-min training sessions. The data were analyzed using SPSS 22, the chi-squared test, independent t-test, paired t-test, and descriptive statistics (p < 0.05).

RESULTS

The mean ages of the intervention and control groups were 32.28 ± 6.14 and 31.84 ± 6.71, respectively. The results showed that the average scores of all constructs of the theory of planned behavior, dental plaque indices (PI), and MDFT in the intervention group significantly changed after the intervention (p < 0.001).

CONCLUSION

According to the results, training based on the theory of planned behavior was effective on dental and oral health behaviors in pregnant women and improved the clinical results of their self-care behaviors. Therefore, training sessions will increase the knowledge of pregnant women, and providing timely consultations and examinations can be helpful and effective in developing oral and dental health behaviors in pregnant women.

The effect of motivational interviewing based on the transtheoretical model on oral cleaning behavior of patients with periodontitis who have undergone implant restoration

BACKGROUND

Implant-restored patients with periodontitis have a higher risk of developing peri-implantitis, and helping them develop oral cleaning habits is significant.

OBJECTIVE

To evaluate the effectiveness of motivational interviewing based on the transtheoretical model on the modification of oral cleaning behaviors of implant-restored patients with periodontitis.

METHODS

Patients with periodontitis (n= 70) who would receive dental implant treatment were included. And they were randomly divided into two groups: experimental (n= 35) and control (n= 35). Control patients received routine oral hygiene education, and those in the experimental group received motivational interviewing based on the transtheoretical model. Oral cleaning behavior was compared between the two groups before and after intervention. In addition, periodontal health status was compared on the day of implant restoration and three months later.

RESULTS

Compared to the control, the experimental group demonstrated significantly better oral hygiene behavior after intervention (P< 0.05). Three months after implant restoration, significantly better results were obtained by the experimental group in terms of mPLI and mSBI (P< 0.05).

CONCLUSION

Motivational interviewing based on the transtheoretical model can effectively improve the oral cleaning behavior and periodontal health of implant-restored patients with periodontitis.

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.

Oral Hygiene Practice among 18-year-old Norwegian Adolescents Using Health Belief Model: A Cross-Sectional Study

Objectives  The aim was to compare oral hygiene practice (brushing/flossing) among 18 years old from two regions, Hordaland County, Norway, and possible perceptional correlates using the Health Belief Model.

Materials and Methods  The participants from six municipalities from the south district with high prevalence of dental caries to six municipalities from the rest of Hordaland county, with low prevalence of dental caries (control), using a web-based questionnaire. Statistical analyses: the Mann–Whitney U test was used and the t -test for independent samples. Bivariate and logistic regression analyses to examine associations.

Results  A total of 416 people participated. The south district’s participants had lesser percentage brushing twice a day and flossing at least once a day, they significantly visited lesser the dental service, perceived more susceptibility to dental caries, and lower benefits of brushing/flossing compared with the controls. Girls (odds ratio [OR]: 0.34) who perceived higher severity of dental caries (OR: 1.86), higher self-identity (OR: 2.14), and lesser barriers to brushing (OR: 0.14) had higher odds to brushing twice a day compared with their counterparts. Girls (OR: 0.34) who perceived higher severity of dental caries (OR: 2.34), higher benefits (OR = 2.8), and lesser barriers to flossing (OR = 0.23) had higher odds to flossing at least once a day compared with their counterparts.

Conclusion  South district’s participants significantly had some of risk factors to the recommended brushing/flossing practice compared with the control and these might help in explaining the difference in oral hygiene practice.

Effect of a health-education program using motivational interviewing on oral health behavior and self-efficacy in pregnant women: a randomized controlled trial

Oral health problems are common among pregnant women. The objective of this study was to examine the effectiveness of motivational interviewing (MI) as a behavior-change technique to enhance self-efficacy and oral health among pregnant women. A randomized controlled trial was conducted with 112 pregnant Iranian women. Women in the intervention group received an education program on oral health using MI during two face-to-face sessions, along with routine health education (two 1-h lectures on oral health changes and needs during pregnancy presented as a lecture by an oral health technician over a 2-wk period). Those in the control group received two 1-h lectures on oral health changes and needs during pregnancy. Oral health behaviors, oral health self-efficacy, and general self-efficacy, were assessed, along with gingival and dental health from baseline to the 3-month follow-up. Analysis of covariance was used to determine differences between intervention and control groups. Scores for both general and specific self-efficacy and for healthy behaviors increased in the intervention group, whereas there was no significant change within controls from baseline to follow-up. Between-group analyses also indicated a significant difference in the scores for self-efficacy and behavior favoring the intervention group. Scores on the gingival inflammation index decreased, as did the number of decayed teeth in the intervention group relative to the control group. The number of filled teeth increased significantly in the intervention group. Health education interventions using MI techniques may help to improve oral health-related self-efficacy and behaviors among pregnant women.
