Impact of oral hygiene and socio-demographic factors on dental caries in a suburban population in Nigeria

Dental Health Knowledge Attitude and Practice Among University of Calabar Students

Introduction Oral health has been linked to aspects of individual knowledge, attitude, and practices. In Nigeria, the increased prevalence of poor oral hygiene has been attributed behavioral factors. Behavioral aspects that include the increased intake of sugary foods and beverages, and lack of proper oral hygiene have been touted as the main causes of poor oral hygiene among university students. The knowledge of oral health is vital owing to its contribution to better oral health; however, unless students develop good oral habits and attitudes and subsequently put them into practice, very little will be realized with regard improvement in oral health and hygiene. Objective This research aimed to explore the knowledge, attitude, and practice of dental care among the University of Calabar students. Method This study was a descriptive cross-sectional study conducted between 2016 and 2017. A standardized questionnaire was used to collect data from 430 student participants in a university using a multi-stage random technique. An inferential statistical approach was adopted to test the relationships represented in the tables. Data were analyzed using the statistical package for social sciences, version 20.0. Result The study included 430 participants, 239 (55.6%) females and 191 (44.4%) males. The survey revealed that 94% of the 404 respondents agreed that poor dental care can cause dental diseases, while only 6% disagreed. Regarding excessive drinking of water, 91% of the respondents agreed that it cannot cause dental disease, 4.2% agreed it could, and 4.8% did not know. Furthermore, 60.2% of the 430 respondents acknowledged that genetic inheritance could cause dental disease, while 21.4% disagreed, and 18.4% did not know. Finally, 74.9% of the respondents knew that trauma to the teeth could cause dental disease, while only 9.3% thought that trauma could not cause illness to the teeth. Regarding attitude to dental care, 232 (54%) respondents agreed that visiting the dentist was necessary, while 164 (38.1%) strongly agreed. Only eight (1.9%) strongly disagreed, while five (1.2%) disagreed that visiting the dentist was necessary. Moreover, 82% of the respondents agreed that bad breath was associated with poor dental care, with 195 (45.3%) respondents strongly agreeing and 158 (36.7%) agreeing. However, 37 (8.6%) disagreed, and 16 (3.7%) strongly disagreed, while 24 (5.6%) were indifferent. As regards practice, most respondents used the up-down technique when brushing their teeth (62.8%), while 17.4% brushed left-right and 19.8% used both methods. Moreover, 67.4% of the respondents brushed twice daily, 26.5% brushed once daily, and only 6.1% brushed after every meal. About half of the students spent one to three minutes brushing their teeth (50.5%), while the other half spent more time. Over half of the students replaced their toothbrushes every three months (57.7%), with the most common reason for replacement being the fraying of bristles. However, the use of dental floss was found to be low. Conclusion The utilization of dental care facilities was low among most University of Calabar students, who did not see the need for dental clinic visits unless they had dental needs. The lack of dental visits was attributed to perceived high dental costs and a lack of time. Targeted interventions and educational programs that address these barriers could promote better oral hygiene practices among the students.

Fewer Children in Families Associated with Lower Odds of Early Childhood Caries: A Sample from Three Countries

Childhood caries experience is influenced by family characteristics and oral health practices in the context of many social-commercial determinants. The aim of this study was to explore the relationship between families' number of children, oral health practices and child caries experience in a convenience sample of 1374 children aged 6 months through 6 years and their families from Ecuador, Nepal, and Vietnam. Data were collected by mother interviews and child dental exams. Multivariate logistic and Zero-Inflated-Poisson regression analyses assessed associations between number of children, oral health practices and decayed, missing or filled teeth (dmft). Families had a mean of 2.2 children (range 1-12); 72% of children had tooth decay, with mean dmft of 5.4. Adjusting for child age, sex, and urban/rural location, a greater number of children in the family was associated with significantly less likelihood of unhealthy bottle feeding practices, having a toothbrush/toothpaste and parent helping child brush, and being cavity-free; higher number of dmft, and greater likelihood of having a dental visit. Early childhood oral health promotion should include focus on oral hygiene and healthy feeding-particularly breastfeeding and healthy bottle feeding practices-as well as access to family planning services and support for childcare.

Association of Early Childhood Caries and Multiple Variable Factors in 3-6-year-old Children

Introduction

Dental caries is a globally prevailing condition. It is a common finding in all age-groups, whether it is young children or adults. Caries not only affects the oral health of an individual, but also the overall health of the individual.

Aims and Objectives

This article focuses on the association of ECC with BMI, SES status, maternal education, birth order, and number of siblings in age group of 3 to 6 year old children.

Material and methods

The study was planned and conducted in the Department of Pedodontics and Preventive Dentistry, Government College of Dentistry, Indore, Madhya Pradesh, India. The study consisted of 200 samples, including both groups. Group I included 100 patients with ECC and group II included 100 patients caries free. Children of age 3-6 years were randomly selected and evaluated for ECC and parameters like weight, height, number of siblings, birth order, SES status, and mothers' education.

Results

Body mass index (BMI) had no significant association with the occurrence of ECC. Statistical significant association was observed between the number of siblings and ECC. The "no caries" was significantly associated with "no sibling" or "one sibling". A significant association between SES status and ECC was observed. The upper and upper middle class had more number of caries free children, whereas the number of participants with ECC was significantly more in the upper lower class. There was a pronounced association between ECC and maternal education.

Conclusion

Researches like these help us to broaden our aspects of understanding that caries is not caused by only one factor but a magnitude of factors. It's prevention should take into consideration not only the dietary habits but also on increasing awareness about importance of oral hygiene and how it can be affected by other social varients.This article focuses on the association of ECC with BMI, SES status, maternal education, birth order, and number of siblings in 3-6-year-old children.

Prevalence of dental caries in the permanent dentition amongst 12-year-olds in Africa: a systematic review and meta-analysis

BACKGROUND

Dental caries (DC) is highly prevalent condition affecting mostly young children. There has been no systematic review done on the prevalence of DC amongst 12-year -olds in Africa. Although some African countries have reported a decrease in DC prevalence, others have shown an increase and it is essential to measure current trends in order to identify strategies and programmes that could assist in reducing DC in Africa. The aim of this systematic review was to determine the prevalence of DC (condition) amongst the permanent dentition of 12-year-old children (population) in Africa (context).

METHODS

A systematic review and meta-analysis was performed. Peer reviewed cross-sectional articles from January 2000 until December 2021 was searched and this included the following databases: Pubmed (Medline); SCOPUS; CINAHL (via EBSCOhost); Academic Search Complete (via EBSCOhost); Dentistry and Oral Sciences Sources (via EBSCOhost); and Science Direct. The search was last updated on the 10th January 2022. Joanna Briggs Institute critical appraisal tools were used to assess risk of bias. Prevalence figures were stratified by Urban/Rural status, country and time using a random-effects model. All studies performed on children 12-year-olds on the African continent were included. The prevalence of DC and the DMFT scores were the primary and secondary outcome measures, respectively. Only articles consisting of 12-year-old children who reside in Africa were included in this study. The systematic review was registered with Prospero CRD42021293666.

RESULTS

18,080 participants were included in this review. A total of thirty studies were included in the review. The pooled effect size of dental caries severity was 1.09 (CI 0.91-1.27) and the overall prevalence was 36% (CI 29.4-41.7%). Eritrea (78%) had the highest prevalence of DC while Zambia had the lowest (11%); Eritrea also had the highest DMFT score (2.5) with Sudan having the lowest score (0.49). Urban cities had the highest DMFT score (1.32, CI 0.97-1.68), compared to rural cities (1.13, CI 0.86-1.4) and there was an increasing trend in DC prevalence over time from 28% (CI 23-34%) in 2000 to 2005 to 57% (CI 43-72%) in studies conducted after 2015. The risk of bias was very low where majority of the studies scored more than 50% in the JBI critical appraisal tool.

CONCLUSIONS

There was a wide discrepancy in the DC prevalence and scores across the different countries, settings (rural versus urban) and there was an increase in the prevalence over time. This review was self-funded.

Caries incidence of the first permanent molars according to the Caries Assessment Spectrum and Treatment (CAST) index and its determinants in children: a cohort study

Background

There are limited information on caries incidence, especially from developing countries, the aim of the present study was to explore caries incidence in the first permanent molar teeth according to the CAST index in 7- to 8-year-old-children and its socio-demographic, oral health related and diet determinants.

Methods

A multi-stage cluster random sample of 7–8 years old children was applied in Tehran, Iran. The oral examination using the CAST index and the Oral Hygiene Index-Simplified (OHI-S) performed by trained dentists in 2017 and 2019 calibrated with an expert (Kappa of 0.89 and 0.76, respectively). A 3-day food record was used to record sugary snacks consumption. Oral health related knowledge of the parents was assessed using a valid and reliable self-administered questionnaire. The data were analyzed using the SPSS software version 23.0 and descriptive and analytical statistics including the negative binomial regression was applied.

Results

Two hundred and ninety schoolchildren aged 7–8 years old were followed up for two years. All of them had complete data obtained via oral examination and questionnaires. The annual caries incidence rate was 0.16 and 53% (95% CI 47.4–58.9) of the children developed at least one new dental caries (enamel or dentine) during two years. Multi-variate analysis revealed that the children of mothers with high school education or diploma (IRR = 1.47, 95% CI 1.02–2.12; p = 0.04) and those with low socio-economic status (IRR = 1.86, 95% CI 1.27–2.73; p < 0.001) were more likely to develop caries. There was no significant association between gender, father’s educational level, child birth order, housing area per person, OHI-S score, oral health knowledge of parents, and sugary snacks consumption per day and caries increment at an individual level.

Conclusion

This 2-year longitudinal study on 7- to 8-year-old children showed that caries incidence according to the CAST index was associated with socio-economic status and mother education but not associated with having 2 or more sugary snack per day and oral hygiene status.

Birth order is associated with caries development in young children: a register-based cohort study

BACKGROUND

Birth order has been shown to affect the health of the child; less is known, however, about how birth order affects caries development in children. Thus, the present study investigated the association between birth order and dental caries development in young children.

METHODS

This retrospective registry-based cohort study included all children born in 2000-2003 who were residing in Stockholm County, Sweden, at age 3 years (n = 83,147). The study followed the cohort until subjects reached 7 years of age. Children with registry data on dental examinations and sociodemographic characteristics at ages 3- and 7 years constituted the final study cohort (n = 65,259). The outcome variable was "caries increment from age 3- to 7 years" (Δdeft > 0) and the key exposure, "birth order", was divided into five groups. A forward stepwise logistic binary regression was done for the multivariate analysis with adjustments for sociodemographic factors.

RESULTS

At age 3 years, 94% had no fillings or manifest caries lesions. During the study period, 22.5% (n = 14,711) developed dental caries. The final logistic regression analysis found a statistically significant positive association between birth order and caries increment. Further, excess risk increased with higher birth order; with the mother's first-born child as reference, risk for the second-born child was OR 1.17, 95% CI = 1.12-1.23; for the third-born child, OR 1.47, 95% CI = 1.38-1.56; for the fourth-born child, OR 1.69, 95% CI = 1.52-1.88; and for the fifth-born or higher birth-order child, OR 1.84, 95% CI = 1.58-2.14.

CONCLUSIONS

These findings show that birth order influences caries development in siblings, suggesting that birth order can be regarded as a predictor for caries development in young children. This factor may be helpful in assessing caries risk in preschool children and should be considered in caries prevention work in young children with older siblings.
