Abstract:
Introduction: Early Childhood Caries (ECC) is a serious public health concern globally especially in developing countries like South Africa. The main source from which infants acquire the causative bacteria - Mutans Streptococci (MS) is their mothers. The mothers with high levels of MS have a greater chance of transmitting the bacteria, particularly if they are involved in practices such as tasting the infant’s food and/or sharing eating utensils. Current research indicates that dental public health programmes fail to prevent ECC because of late intervention.
Objective: This study sought to determine the existing knowledge, attitudes and perceptions (KAP) of pregnant women about ECC in a population in Tshwane district, Gauteng province, South Africa and to compare these KAP across socio-economic groups (SES).
Methodology: A cross-sectional analytical study involving consenting pregnant women recruited from selected private and public antenatal healthcare facilities in the Tshwane District area was conducted. This study involved the use of a validated self-administered structured questionnaire and an oral epidemiological clinical examination (modified by WHO Oral Health Assessment 1997 Guidelines). One calibrated examiner using a dental explorer and a mouth mirror under natural light carried out the oral examination. Data analysis included descriptive statistics, principal component analysis to obtain a composite score for participant’s attitude towards ECC; and chi-square and independent student’s T-test to compare different groups. Significance level was set at p<0.05.
Results: Response rate was 88.9% (n=353). Respondents’ age ranged from 18-44years (Mean age=31years). Only 18.7% of the respondents had complete knowledge of the cause of dental caries i.e. both sugar (diet) and biologic agent (bacterial plaque) whilst over half of the respondents (55.5%) mentioned only one factor. The participants’ knowledge of the cause of ECC was significantly associated with SES. A few mothers-to-be (13.9%) believed in the caries transmission from mother to child. Reported mean age for the child’s first dental visit was 2 years and 8 months. Only a quarter of respondents received oral health education for their unborn child during the antenatal visits. The majority of the pregnant women (93.8%) expressed the desire to receive information during the antenatal visit. The participants’ attitudes towards ECC was significantly associated with SES.
The caries prevalence of the pregnant women was high at 64.3%, with mean DMFT of 2.97(SD 3.20). High participant DMFT was significantly associated with reports of ‘rotten teeth’ in their other children. Only 19.3% mothers-to-be had visited a dental care provider in the last 6-months.
Conclusion: The knowledge of the pregnant women studied on ECC is incomplete and limited, while their attitudes and perceptions towards ECC was satisfactory. Therefore there is a need for the integration of oral health education with maternal and child health activities in both antenatal and post-natal clinics. There is a need for the oral health professionals to collaborate with other health works to reduce the prevalence of ECC.
