Abstract

Background. Pregnancy is a unique time in a woman's life and is characterized by complex physiological changes. These changes can adversely affect oral health. Oral health is a state of being free from chronic mouth and facial pain, oral and throat cancer, oral sores, periodontal (gum) disease, tooth decay and tooth loss, and other diseases, and disorders that affect the oral cavity. Risk factors for oral diseases include unhealthy diet, tobacco use, harmful alcohol use, and poor oral hygiene (WHO). Multiple studies have shown an association between periodontal infection and adverse pregnancy outcomes, such as premature delivery and low birth weight. Aim of this study assess women’s knowledge towards oral and dental health during pregnancy and to examine their self-care practices in relation to oral and dental health. Methodology The research will be conducted at randomly governmental primary health care centers and schools in Riyadh (Dawadmi region). A Quantitative Descriptive cross-sectional study was carried out. two-hundred Saudi pregnant women selected randomly. Women who gave informed consent were asked to complete a self-administered questionnaire and return it to the researcher A Structured questionnaire will be developed consisted of three parts, Demographic characteristics part, level of women`s Knowledge regarding oral health part & Self-care practice regard oral health care. Results, Conclusion & Recommendation. Age of participant women’s between 28 – 38 years (43.2%). Most of the participants had number of pregnancies between 4-6 (38.5 %). Regarding the level of knowledge about oral health, this study showed that 45% of mother had poor knowledge, and there is a significant relationship between the level of practice and the educational, professional status and attendance to antenatal clinic, which was started by 65% of the sample on time, however, they did not visit the dentist. This study recommends that the implementation of oral health programs in prenatal services is essential to delivery of dental care and decreasing the potential oral problems among pregnant women, as well as conducting careful screening of oral risks, and assisting women in obtaining regular dental care.

1. Introduction

Oral health is a state of being free from a chronic mouth and facial pain, oral and throat cancer, oral sores, birth defects such as cleft lip and palate, periodontal (gum) disease, tooth decay and tooth loss, and other diseases and disorders that affect the oral cavity. Risk factors for oral diseases include unhealthy diet, tobacco use, harmful alcohol use, and poor oral hygiene ¹ Women need to be aware of the importance of oral health care during and after pregnancy for themselves as well as their children. Early education programs aimed at pregnant women can help to prevent oral diseases in both mother and infant. Dental professionals can play an important role in assuring the well-being of women during their pregnancies by promoting and maintaining their oral health ^{1, 2}.

Studies have confirmed the safety and effectiveness of providing oral health care during pregnancy. Pregnancy by itself is not a reason to defer routine dental care and necessary treatment for oral health problems. Diagnosis and treatment, including dental X-rays, can be undertaken safely during the first trimester of pregnancy. Treatment can be provided throughout pregnancy; however, the time period between the 14th and 20th week is considered ideal. ³.

Periodontal diseases produce a wide range of clinical signs and symptoms such as tooth loss, altered appearance, pain, bleeding, bad breath and impaired quality of life ^{4, 5, 6}. Loss of posterior occluding supports has been associated with impaired chewing efficiency and inadequate nutrition ⁷ which may result in the loss of important nutrients due to over preparation of food in order it easier to eat. Inadequate nutrition during pregnancy may lead to poor fetal growth and possibly interfere with kidney development which in turn leads to raised blood pressure in adulthood. Other changes associated with pregnancy include chloasma, facial telangiectasia, sialorrhea, tooth surface loss usually related to vomiting when severe (hyperemesis gravidarum), increased mobility of teeth and oral aphthate ^{8, 9, 10}.

Morning sickness is a common problem which is encountered by women, early in their pregnancies. The gastric acids which are present in the emesis, erode the enamel on the inner surface of the teeth, most commonly the front teeth ¹¹. This is a concern only in the cases with frequent vomiting, for example, in bulimics and in patients with hyperemesis gravidum. Erosion of the enamel can easily be controlled by advising the patients to rinse their mouths thoroughly after vomiting, with a solution that contains sodium bicarbonate. Sodium bicarbonate neutralizes the acids and it prevents the damage which is caused by the residue which remains on the teeth. Erosion of the teeth which are on the lingual and palatal surfaces of the incisors was mentioned in a case report, but as per our knowledge, there is no clinical study which is available to support this finding ^{12, 13, 14}.

Checking the salivary estrogen level has been suggested as a screening test to detect the risk potential for preterm labor. The recent studies have suggested a link between periodontal disease and preterm low birth weight. The periodontal disease seemed to be independent of good oral hygiene and a periodontal treatment ^{15, 16}.

The opinions of nursing practitioners and certified nurse midwives on oral health care for pregnant women were also sought by the North Carolina research group. Among 219 nurses, 86% reported referring patients for dental health screening; many showed equivocal information regarding the more favorable prenatal trimester to initiate dental treatment but admitted the need to collaborate with dental professionals to reduce risks during pregnancy ⁴.

Assess women’s knowledge towards oral and dental health during pregnancy and to examine their self-care practices in relation to oral and dental health.

Presents table shows the association between sociodemographic data and knowledge of pregnant women. A chi-square test was used to test the association of pregnant women knowledge with age and educational level A statistical significant was observed (x²= 0.072, 0.021) respectively. No significant was observed between Professional status and degree of knowledge of pregnant women Also, no significant between level of knowledge and family income status (Table 6).

Regarding the association between obstetric history and degree of knowledge of pregnant women. A chi-square test was used. A statistically significant was observed between level of knowledge and go to antenatal care clinic on the other hand no significant was observed between level of knowledge and numbers of pregnancies, Numbers of deliveries, number of abortion & The number of living children (Table 7).

Table 8 represent the association between socio-demographic data and degree of self-care Practice of pregnant women. A chi-square test used, no significantly was observed between age, family income and number of family (X²= 0.456, 0.257 & 0.298) respectively. The variable of educational level was significantly associated with level of self-care Practice of pregnant women. A statistical significantly was observed between Professional status and degree of self-care Practice of pregnant women.

Presents Table 9 represent the association between Number of pregnancies and degree of self-care Practice of pregnant women. Not significant observed between The of Number of pregnancies and number of deliveries respectively. A chi-square test was used to test was used to test the association of pregnant women self-care Practice level with antenatal care clinic. The variable of antenatal care clinic was significantly associated with level of Practice of pregnant women. A significant statistical was observed in the association between the months go to care for pregnancy and degree of self-care Practice of pregnant women.

There is highly significant correlation (Spearman Correlation =0.414, p-value=0.001). They are strong. Positive correlation between knowledge and practice (Table 10)

3. Discussion

Good oral health during pregnancy can not only improve the health of the pregnant mother but also potentially the health of the child. The present study aims to assess the knowledge and Self-care practice toward oral health during pregnancy among Saudi women.

The majority of women in this study between 28-38 years old with university degree educational level About 38.5% of the sample pregnant for 4-6 months and those people need more health education about calcium and vitamin D deficiency and this reflects that the Saudi women like to pregnant for several time, as a maternal nurse must put more attention for these women.

Related to the degree of knowledge about oral health this study shows about 45% of participants have poor knowledge in state of income state very good and the mother attends in early prenatal care, still this of women high risk group. Study of ¹⁶, found that 43% of women surveyed reported having heard about the possible connection between health in pregnancy and oral health and 39% thought that tooth and gum problems could affect outcomes of pregnancy.

On other study have shown periodontal disease to be significant risk factor for pregnancy outcomes as preterm low birth weight ^{19, 25, 26}. In other study mothers were not certain about this relationship, therapy indicating that pregnant women require education on oral health maintenance and the link between oral health of the mother and overall health of the newborn (Turkish Women's self-reported knowledge and behavior towards oral health during pregnancy).

Another finding of this analysis, about (75.5) didn’t know about the harmful of brushing the teeth directly after vomiting. The majority of the pregnant women in this study (97 %) they have toothbrush and about (61.8) they have mistaken. The finding of the present study was (31.7) they didn’t use flossing on oral health practice However, there were a few questions on basic oral health that Saudi women missed as the majority of women did not know what plaque was and that the best time to floss is before brushing. This indicates that women were not aware of certain oral health practices that may help reduce periodontal disease, a finding that is also supported by previous studies. This shows that in three different populations, women's oral health knowledge, although adequate in most areas, can use some improvement. This is important information that dentists should know as it may have implications on the information they give women. Furthermore, these women will soon be mothers, who will influence their children's oral health. Although this study was not focused on children's oral health, this issue is one that future research can further explore ^{4, 8, 17, 18}.

According to study among Turkish women's toward oral health during pregnancy, many women do not seek dental care during their pregnancy, and those who do often confront unwillingness by dentists to provide care ^{19, 20, 21}.

In this study, some of the important knowledge found to be poor among the pregnant women, Like Vomiting with nausea in the first months contain acids damage the outer layer of the teeth while (57.5%) they didn’t know. Nausea and vomiting during pregnancy cause extensive erosion of the tooth surface leading to deteriorating oral health status which has been associated with adverse pregnancy outcomes such as pre-term births, development of pre-eclampsia and delivery of a "small-for-gestational-age" infant. It is imperative however; that management of nausea and vomiting should involve measures targeted at reducing the effects of the hydrochloric acid content of gastric juice on the teeth as well as improve oral hygiene practices to prevent poor oral health ^{22, 23, 24}.

In the present study there was a significant relationship between the level of self-care practice about oral health during pregnancy and level of knowledge, the majority of women did not know what plaque was and that the best time to floss is before brushing. This indicates that women were not aware of certain oral health practices that may help reduce periodontal disease, a finding that is also supported by previous studies ^{27, 28}. This represent that three different populations, women's oral health knowledge, although adequate in most areas, can use some improvement. This is important information that dentists should know as it may have implications on the information they give women. Furthermore, these women will soon be mothers, who will influence their children's oral health. Although this study was not focused on children's oral health, this issue is one that future research can further explore ^{1, 29, 30} Saudi women's knowledge was lacking in certain important areas of oral health Self-care practices specific to pregnancy. For example, most women did not know that pregnancy a reason of why Saudi women were not aware of these pregnancy-specific oral health practices. By not attending dental check-ups, they may be missing out on receiving pertinent information from their dentists. Previous studies have also found that women tend to decrease or stop attending dental check-ups during their pregnancy. Thus, it is important for dentists and health care practitioners to recognize that even women with dental insurance and regular dental check-up attendance before pregnancy may still need to be encouraged to continue during pregnancy ^{8, 32, 33, 34}.

Previous studies have shown periodontal disease to be a significant risk factor for pregnancy outcomes such as pre –term low birth weight .In the present study, mothers were not certain about this relationship, thereby indicating that pregnant women require education on oral health maintenance and link between oral health of the mother and overall health of the new born ^{35, 36}.

According to the association of women's health, Obstetric and neonatal nurses American Academy of Pediatric Dentistry ³⁷, stated most of the mothers do not go for dental care during pregnancy, In addition, only 34% of Medicaid – insured pregnant women see a dentist, whereas 55% of pregnant women with private insurance carriers do. The finding of the present study indicated about (65.2) of pregnant women didn’t go to dental clinic during their pregnancy.

The oral health guidelines encourage dentists to provide regular dental care for pregnant women and recommends that prenatal practices initiate oral health programs at time of prenatal visit. They also stress the importance of active communication between dental, prenatal and paediatric care providers for purposes of better risk assessment, referral and intervention ^{14, 38, 39, 40}.

4. Conclusions and Recommendations

Saudi pregnant women, despite having knowledge that adverse pregnancy events related to oral health, didn’t seek oral care during pregnancy. We can less likely to have dental problems during pregnancy if you already have good oral hygiene habits. Prenatal care offers one of the best time for addressing oral health in Saudi pregnant women, with each prenatal visit are scheduled. And the visit focus on, oral health care, treatment and education.

5. Recommendations

Developing health education programme should be built in to antenatal care unit, primary health care and hospital. Conduct careful screening of oral risks, and assist women in obtaining regular dental care are essential elements of oral health in prenatal programs.
