| Introduction|| |
Periodontitis is the inflammatory disease of the periodontium affecting 30% of women among the childbearing age., Periodontal disease is a chronic inflammatory disease in response to bacterial plaque and microbial complex. Maintaining good oral hygiene is a key component of general well-being in women's life, which is important during the preconception period. There are various physical, physiological changes that take place during pregnancy. Hormonal changes during maternal life, like estrogen and progesterone, can cause inflammation, bleeding gums, pregnancy tumor, increased sensitivity, and risk of bacterial infection., The prevalence of gingivitis in pregnancy was shown to be 30%–100%.,,, The changes in hormone levels have found to affect periodontal disease progress and healing. These irregularities can lead to increased gingival vascularization and decreased immunity. Increased level of Prevotella species during pregnancy utilizes the steroid hormones for their growth, which indirectly tend to increase gingival inflammation.,, Maternal periodontitis has proven risk of preterm low birth weight infants in the scientific literature.,,,,,, Pregnant women should be aware of the changes that could be expected during maternal life so that importance of maintaining oral hygiene during pregnancy is known and the adverse outcomes of poor oral health could be avoided. A pilot study was conducted with 160 pregnant women in 2016 among women visiting the gynecologist department in Sathyabama Dental College and Hospital, Chennai. The results of this study showed that oral hygiene awareness among pregnant women was least among those subjects who did not complete basic school education. This was the motive to conduct the present survey with a sample size of 500 pregnant women in Chennai. This study was carried out to assess the awareness among pregnant women about oral hygiene and if the level of education level could play a role in acquiring knowledge of adverse outcomes of poor oral health.
| Materials and Methods|| |
This was a descriptive cross-sectional study conducted among 500 pregnant women attending maternity clinics in Chennai, Tamil Nadu. The study was approved by institutional ethics and research committee. Pregnant women who gave informed consent were recruited for the study. A self-administered questionnaire was formed in English and Tamil language. The questionnaire was validated using the Cronbach alpha test using SPSS Package Software (Statistical Package for the Social Sciences package v.21 software (SPSS Inc., Chicago, IL, USA). Pilot study was conducted with 160 pregnant participants. The questionnaire consisted of open- and closed-ended responses. A trained investigator was recruited to help the participants to complete the questionnaire. The questionnaire consisted of 16 questions divided into four sections. The first section included sociodemographic data such as age, education status, trimester, occupation, and address. The second section consists of details related to oral hygiene practises and awareness of gingival diseases such as frequency of brushing, adjuvant oral hygiene aids, bleeding gums, and the trimester they considered safe for dental therapy was noted. Third section consisted of awareness about factors that could affect the fetus like self-medication, dental radiation exposure, and influence of smoking. A fourth section included a question to know if their gynecologist referred them to dental check-up during prenatal period.
Five hundred pregnant women in the age group of 18–40 years made up the study population. The subjects were categorized as Group A-school educated (Educated up to 12th Standard), Group B-under graduate (completed graduation), and Group C-(completed master degree), [Graph 1]. The subjects were randomly selected and then categorized based on their education status into the above three categories.
- Pregnant women in the age group of 18–40 years
- Systemically healthy.
- Medically compromised
- On antibiotic therapy for the past 6 months
| Results|| |
Chi-square is used to find statistical significance between education status and oral hygiene awareness. The P value less than the standard value 0.050 was considered as statistically significant. Descriptive analysis is made to find the percentage for each category.
The first section of questionnaire consists of sociodemographic data. The mean age of the subjects was 27.16 years. The age ranged from 18 years to 40 years. The subjects were categorized based on the education status as Group A with 150 participants who were school educated (educated up to 12th standard), Group B with 225-under graduate (completed graduation), and Group C with 125 participants-(completed Master degree). Majority of subjects (45%) belonged to Group B, [Graph 1].
Awareness on oral hygiene practices
It was found that brushing after every meal and use of adjunctive oral hygiene aids like use mouth rinse and interdental aids was mainly practiced among Group B (n = 225). 30.7% used mouth rinses and 3.6% used interdental aids. In Group C (n = 125), 39.2% used mouth rinses and 6.4% used interdental aids. In Group A (n = 150), 11.5% used mouth rinses and 2.7% used interdental aids. The usage of adjunctive aids for maintaining oral hygiene was which was statistically significant with P = 0.005 and 0.012, respectively, among Group B and Group C, [Graph 2], [Graph 2]A and [Table 1].
Awareness of gingival diseases
Bleeding gums during pregnancy were not noticed by 62.7% of Group A, 70.2% of Group B and 60.8% of Group C with a P = 0.013, which was significant. About 69.8% of Group B and 75.2% of Group C felt that dental treatment is necessary for bleeding gums compared to 38.7% of Group A. 59.1% of Group B and 64.8% Group C and 46% of Group A were aware that gingival diseases could cause adverse effect on pregnancy with P = 0.003 and 0.004 which was statistically significant [Graph 3], [Graph 3]A, and [Table 1].
Awareness on factors that affect fetus
About 20.7% of Group A, 8% of Group B, and 10.4% of Group C respondents had taken medications without prescriptions with a P = 0.006. 93.6% of Group C and 83.1% of Group B were aware that taking medications without prescriptions could have adverse effects on the fetus compared to 78% of Group A with P = 0.002, which was significant. Seventy-two percent of Group A had not visited a dentist since their pregnancy, 40% of Group B and 40.8% of Group C visited the dentist every 6 months with a P = 0.049 and 0.032, respectively, which was statistically significant. Forty-six percent of Group A, 15.6% of Group B, and 9.6% of Group C was not aware that frequent exposure to radiation could affect the infants with P = 0.000, which was highly significant [Graph 4] and [Table 1].
Safer trimester for undergoing dental treatment
Majority of Group A respondents 31.3%, 29.3% of Group B, and 20.8% of Group C responded that first trimester would be safe for the dental procedure with P = 0.000. About 57.3% of Group B and 76.3% Group C compared to 45.3% of Group A felt that second trimester would be safer to undergo dental treatment with P = 0.000, which was statistically significant. About 23.3% of Group A, 13.3% of Group B, and 5.6% of Group C responded for third trimester to be safe for dental treatment with P = 0.000, which was highly significant [Table 1].
Premature delivery and smoking practice
Twelve percent of Group A had a history of premature delivery compared to 3.1% of Group B and 4% of Group C with P = 0.001, which is statistically significant. Two percent of Group A and 2.4% of Group C had a history of the smoking habit. The habit of smoking was not significant among all the three groups of respondents. Majority of the respondents 88% of Group A, 87.1% in Group B, and 91.2% of Group C were aware that smoking and drinking alcohol could have adverse effects on their infants with a P = 0.054, which was significant [Table 1].
Gynecologist's referral for dental check up
Among all the 500 respondents, only 8% of Group A, 6.2% of Group B, and 6.4% of Group C was advised by their gynecologist to visit the dentist during the pregnancy checkup. Ninety-two percent of Group A, 93.8% of Group B, and 93.6% of Group C were not referred to dental check-up during their pregnancy with P = 0.782 [Graph 3], [Graph 5] and [Table 1].
| Discussion|| |
In our survey, it was found that education status played an important role in the attitude toward awareness about oral hygiene practices among Group B and Group C respondents. The awareness about bleeding gums, dental therapy and the effect of periodontal diseases on preterm low birth weight infants was known among majority of Group B and Group C compared to Group A respondents. The gingival and periodontal disease during pregnancy is due to an increase in the level of progesterone and estrogens are well documented in literature. There are variations in the levels of hormones in each trimester, thereby making the pregnant women more prone to develop periodontal disease. A similar study suggested the need for educational intervention and preventive health programs during pregnancy. Another study concluded that high literacy levels were co related to awareness and knowledge on health parameters. Majority of the respondents in our survey belonged to 2nd trimester (40%) and third trimester (32%) belonged to Group B. In regard to knowledge and awareness of oral hygiene practices, all practised brushing of teeth as a daily routine, but adjuvant of oral hygiene aids like mouth rinse, interdental aids were mostly used among Group B and Group C. This could be correlated to the role of educational intervention in awareness. In the section about knowledge on the factors that could affect the fetus, like radiation exposure, self-medication, regular dental visits, influence of smoking and its effect on pregnancy, it was reported that most Group A respondents took medications without prescriptions. About 72% of Group A never visited dentist where 40% of Group B and 40.2% of Group C visited the dentist every 6 months. Self-medication is a downturn problem and 10% of birth defects are mainly due to exposure of drugs taken without prescription. Out of several factors that influence the use of self-medication like age, income, people perception of disease, education level is also one of the factors. Majority of Group B and Group C was aware that it was safer to undergo dental treatment in second trimester. Majority of the respondents knew that environmental factors like smoking and alcohol could cause adverse effects on pregnancy outcomes. Smoking is a modifiable risk factor with can cause morbidity and mortality. Studies conducted on smoking and its effects on pregnant women found a need for educational intervention.,, The percentage of pregnant women referred to dental check up was very low. About 6.2% of Group B, 6.4% of Group C and 8% of Group A pregnant women were referred to dental check up by their gynecologists. The percentage of subjects referred to dental check up by gynecologist in our survey is less compared to studies conducted by Penmetsa et al. and Patil et al. 7.97% and 25% of the respondents were sent for dental referral, respectively. Pregnant women spend most of the prenatal period under the care of their gynecologists., The most reliable health practitioner during the prenatal and postnatal periods would be the gynecologist. During maternal life, there is fear among women of the risk to the fetus if dental therapy is done. These misconceptions could be cleared only with the advice of medical health practitioners, in whom the pregnant women would have an inbuilt trust.
In our survey, the respondents included were from Chennai city, and hence, the results of the study cannot be generalized for a wide population. There was unequal distribution of participants in the three categories, which has given variations in the results. The barriers to undergo dental treatment during pregnancy could not be covered within the scope of this survey.
| Conclusion|| |
This survey is a small insight to current existing awareness on oral hygiene measures followed by pregnant women. It is very evident within the limits of our survey that education level has an important stand in the awareness gained among the three groups of respondents. Oral hygiene and practices were highly prevalent among the educated Groups B and C compared to Group A. There is a need for medical health practitioners and the gynecologists to educate and recommend their patients about oral hygiene and risk of preterm low birth weight infants associated with poor oral hygiene. A need to mandate specific guidelines to include routine dental check up for expected mothers.
