Factors associated with dental clinic use by clients in Nigeria during the COVID-19 pandemic.

BACKGROUND: Nigeria, like many other countries, faced challenges in dental care provision during the COVID-19 pandemic, necessitating limited care to emergencies only. However, the impact of restricted access to dental services on oral health remains a concern, particularly with preventive maintenance care. This study aims to identify the factors associated with dental service utilization during the COVID-19 pandemic among patients attending dental clinics in Nigeria, and their sources of information about COVID-19. METHODS: This cross-sectional study recruited 500 participants who had visited dental clinics before and during the pandemic. Data were collected through telephone interviews and online questionnaires between September and December 2021. Inferential analyses were conducted using ordered logistic regression models to assess the association between the independent (awareness of emergency dental treatments, knowledge of COVID-19 transmission routes in dentistry, awareness of required preparations in dental practice settings, fear of COVID-19 infection in dental settings), and dependent (utilization of dental services during the pandemic) variables after adjusting for confounding variables (age, sex, educational status, COVID-19 vaccinations status and COVID-19 status of live-in residents). The sources of COVID-19 information by dental patients was also identified. Statistical significance was established at 95% confidence level with a p value < 0.05. RESULTS: Many participants were males (51.2%) and had tertiary education (61.6%). Fear of COVID-19 infection in dental settings was significantly associated with lower odds of utilizing dental care services during the pandemic (Adjusted Odds Ratio: -0.06, 95% Confidence Interval: -0.08, -0.01). The main sources of COVID-19 information were mass media and social networks, with only 42% receiving information from dental professionals. CONCLUSION: Fear of COVID-19 infection in dental settings significantly influenced dental service utilization during the pandemic. Strategies to address fear and improve communication channels between dental professionals and patients are essential for promoting oral health during similar crises.

Age-specific associations with dental caries in HIV-infected, exposed but uninfected and HIV-unexposed uninfected children in Nigeria.

BACKGROUND: HIV infection and its management confer a substantial health burden to affected individuals and have been associated with increased risk of oral and dental diseases. In this study, we sought to quantify HIV-associated differences in the prevalence and severity of dental caries in the primary and permanent dentition of 4-11-year-old Nigerian Children. METHODS: We used clinical, laboratory, demographic, and behavioral data obtained from an ongoing cohort study of age-matched HIV-infected (HI, n = 181), HIV-exposed-but-uninfected (HEU, n = 177), and HIV-unexposed-and-uninfected (HUU, n = 186) children. Measures of dental caries experience (i.e., prevalence and severity) were based on dmft/DMFT indices recorded by trained and calibrated clinical examiners. Differences in primary and permanent dentition caries experience between HI, HEU, and HUU were estimated using multivariable logistic and negative binomial regression modeling. RESULTS: HI children had significantly higher caries experience (33%) compared to HEU (15%) and HUU (22%) children. This difference persisted in fully adjusted analyses [odds ratio (OR) = 1.6; 95% confidence interval (CI) = 1.0-2.6], was most pronounced in the permanent dentition (OR = 3.4; 95% CI = 1.2-9.5), and mirrored differences in caries severity. While molars were predominantly affected in both primary and permanent dentitions, caries lesion patterns differed between dentitions. Caries severity was significantly associated with hypoplastic primary teeth, gingival inflammation, and lower CD4 counts. CONCLUSIONS: We found that the higher prevalence and severity of dental caries among HI children was driven by increased burden of permanent dentition caries compared to their uninfected counterparts. The dentition-specific associations identified in this study highlight the need to design and implement age-specific caries prevention strategies. These may include intensified oral hygiene regimens aimed at mitigating the cariogenic impact of hyposalivation among HI children. Similarly, the long-lasting impacts of developmental defects of the enamel in the primary and permanent dentitions must not be ignored.

Risk indicators for dental caries, and gingivitis among 6-11-year-old children in Nigeria: a household-based survey.

BACKGROUND: There is little is known about the factors associated with caries experience and gingivitis among 6-11-year-old children in Nigeria. The aim of the study was to determine the prevalence and preventive oral health behaviors associated with caries and gingivitis among 6-11-year-old children in Nigeria. METHODS: A cross-sectional questionnaire-based survey was conducted in Ile-Ife, Nigeria. The dependent variables were caries and gingivitis. The dmft/DMFT index was used to assess dental caries experience (present or absent) and caries severity. The gingival index was used to assess the prevalence (present or absent) and severity of gingivitis (healthy gingiva/mild gingivitis versus moderate/severe gingivitis). The independent variables were preventive oral health behaviors (frequency of daily tooth brushing, frequency of consumption of refined carbohydrates in-between-meals, use of fluoridated toothpaste, and use of dental floss, history of dental service utilization). A series of logistic regression analysis models were constructed to determine the associations between the dependent and independent variables after adjusting for confounders (age, sex, and socioeconomic status). RESULTS: There were 69 (5.2%) children with caries. The mean (standard deviation) dmft was 0.08 (0.457) and the mean DMFT was 0.02 (0.159). There were 839 (63.3%) children with gingivitis with a mean (SD) gingival index score of 0.503 (0.453). Children who seldom or never used fluoride toothpaste had significantly higher odds of developing moderate to severe gingivitis (AOR; 1.671; 95% CI: 1.003-2.786; p = 0.049). Children with middle socio-economic status had significantly lower odds of developing moderate to severe gingivitis (AOR: 0.573; 95%CI: 0.330-0.994; p = 0.048). There were no risk indicators identified for caries. CONCLUSION: The prevalence of dental caries was low while the prevalence of gingivitis was high in the study population. The daily used of fluoridated toothpaste seem to reduce the risk for moderate/severe gingivitis. Further studies are needed to understand these findings.

Associations between mental health problems and risky oral and sexual behaviour in adolescents in a sub-urban community in Southwest Nigeria.

BACKGROUND: This study determined the association between mental health and risky oral health and sexual health behaviours. METHODS: A household cross-sectional survey was conducted in Ile-Ife, Nigeria between December 2019 and January 2020. Data were collected from 10 to 19-year-old on the sociodemographic profile (age, sex at birth and socioeconomic status); mental health problems (psychological distress, depressive symptoms and suicidal ideation); and mental (smoking habit, consumption of alcohol, use of psychoactive substances), sexual (history of vaginal or anal sexual intercourse; transactional sex, multiple sex partners, use of condom at last sexual intercourse) and oral (frequency of daily tooth brushing, daily frequency of consumption of refined carbohydrate in-between-meals, frequency of use of dental floss, history of dental service utilization in the last 12 months and dental anxiety) health risk factors. Binary logistic regression analysis was conducted to determine the association between risky oral (neglecting to brush twice daily and frequent consumption of refined carbohydrates in-between-meals), and sexual (neglecting to use condoms during the last sex act and having multiple sex partners) health behaviours as outcome variables, and mental health status as the explanatory variables. An ordinal logistic regression model was also developed where the outcome variable was the number of risky health behaviours. The models were adjusted for the socio-demographic variables and history of dental service utilisation in the last 12 months of the survey. RESULTS: High psychological distress was significantly associated with lower odds of frequent consumption of refined carbohydrates in-between-meals (AOR = 0.32; 95%CI 0.23, 0.47), and having multiple sex partners (AOR = 0.10; 95%CI 0.02, 0.57); but higher odds of having a higher number of risky behaviours (AOR = 3.04; 95%CI 2.13, 4.33). Having depressive symptoms was significantly associated with higher odds of neglecting to use condom at the last sexual intercourse (AOR = 7.20; 95%CI 1.94, 26.76) and having multiple partners (AOR = 95.43; 95%CI 24.55, 370.90). Suicidal ideation was significantly associated with lower odds of neglecting to use condom at the last sexual intercourse (AOR = 0.00; 95%CI 0.00, 0.00) and having multiple sex partners (AOR = 0.00; 95%CI 0.00, 0.00). CONCLUSION: The associations between psychological distress and oral and sexual health risk behaviours in adolescents seem complex and need to be studied further.

Association between mental health, caries experience and gingival health of adolescents in sub-urban Nigeria.

BACKGROUND: This study assessed the association of mental health problems and risk indicators of mental health problems with caries experience and moderate/severe gingivitis in adolescents. METHODS: A cross-sectional household survey was conducted in Osun State, Nigeria. Data collected from 10 to 19-years-old adolescents between December 2018 and January 2019 were sociodemographic variables (age, sex, socioeconomic status); oral health indicators (tooth brushing, use of fluoridated toothpaste, consumption of refined carbohydrates in-between-meals, dental services utilization, dental anxiety and plaque); mental health indicators (smoking habits, intake of alcohol and use of psychoactive drugs) and mental health problems (low and high). Gingival health (healthy gingiva/mild gingivitis versus moderate/severe gingivitis) and caries experience (present or absent) were also assessed. A series of five logistic regression models were constructed to determine the association between presence of caries experience and presence of moderate/severe gingivitis) with blocks of independent variables. The blocks were: model 1-sociodemographic factors; model 2-oral health indicators; model 3-mental health indicators and model 4-mental health problems. Model 5 included all factors from models 1 to 4. RESULTS: There were 1234 adolescents with a mean (SD) age of 14.6 (2.7) years. Also, 21.1% of participants had high risk of mental health problems, 3.7% had caries experience, and 8.1% had moderate/severe gingivitis. Model 5 had the best fit for the two dependent variables. The use of psychoactive substances (AOR 2.67; 95% CI 1.14, 6.26) was associated with significantly higher odds of caries experience. The frequent consumption of refined carbohydrates in-between-meals (AOR: 0.41; 95% CI 0.25, 0.66) and severe dental anxiety (AOR0.48; 95% CI 0.23, 0.99) were associated with significantly lower odds of moderate/severe gingivitis. Plaque was associated with significant higher odds of moderate/severe gingivitis (AOR 13.50; 95% CI 8.66, 21.04). High risk of mental health problems was not significantly associated with caries experience (AOR 1.84; 95% CI 0.97, 3.49) or moderate/severe gingivitis (AOR 0.80; 95% CI 0.45, 1.44). CONCLUSION: The association between mental problems and risk indicators with oral diseases in Nigerian adolescents indicates a need for integrated mental and oral health care to improve the wellbeing of adolescents.

Individual and familial factors associated with caries and gingivitis among adolescents resident in a semi-urban community in South-Western Nigeria.

OBJECTIVES: We describe the prevalence, and individual and familial risk indicators for dental caries and gingivitis among 10-19-year-old adolescents in Ile-Ife, South-West Nigeria. METHODS: This cross-sectional study collected data through household surveys conducted between December 2018 and January 2019. Adolescents were recruited through multistage sampling. Oral health outcomes were caries, measured by the 'Decayed, Missing due to caries, and Filled Teeth' (DMFT) index, and gingivitis, measured by the Loe and Silness gingival index. Explanatory variables were individual (sex, age, oral health perception) and familial (socioeconomic status, birth rank, family size and parental living status) factors. Oral health behaviors (daily tooth-brushing, use of fluoridated toothpaste, consuming refined carbohydrates in-between meals, use of dental floss, dental service utilization in past 12 months, and smoking habits) were treated as confounders. Poisson regression models with robust estimation were constructed to determine associations between explanatory factors and oral health outcomes. RESULTS: A total of 1472 adolescents were surveyed. Caries prevalence was 3.4%, with mean (standard deviation) DMFT of 0.06 (0.36) and plaque index of 0.84 (0.56). Only 128 (8.7%) adolescents brushed their teeth twice daily, 192 (16.1%) used dental floss daily, 14 (1.1%) utilized dental services in the last 12 months, and 508 (36.1%) consumed refined carbohydrates in-between meals less than once daily. The proportion of respondents who currently smoked cigarettes was 1.6%, and 91.7% of respondents used fluoridated toothpaste daily. The adjusted prevalence ratio of having caries increased by 18% for every additional age-year (APR: 1.18; 95% CI 1.004, 1.34). Additionally, participants with high socioeconomic status had significantly lower prevalence of caries compared to those with lower status (APR: 0.40; 95% CI 0.17, 0.91). Moderate/severe gingivitis was significantly associated with higher frequency of consuming refined carbohydrates in-between meals (APR: 2.33; 95% CI 1.36, 3.99) and higher plaque index scores (APR: 16.24; 95% CI 9.83, 26.82). CONCLUSION: Caries prevalence increased with increasing age and was higher among Nigerian adolescents with low socioeconomic status, while moderate/severe gingivitis was associated with frequent consumption of refined carbohydrates and higher plaque index score. While behavioral interventions may reduce the risk of gingivitis, structural interventions may be needed to reduce the risk for caries in this population.

Associations between depression and gingivitis among adolescents resident in semi-urban South-West Nigeria.

OBJECTIVE: None of the past studies that had showed a linked between oral and mental health among adolescents was conducted in Nigeria. The objective of this study was to determine the association between gingivitis and depression among adolescents in Ile-Ife, South-West Nigeria. METHODS: This cross-sectional study collected data through a household survey conducted between December 2018 and January 2019. Adolescents aged 10 to 19 years old were identified using multistage sampling. The study outcome measure was gingivitis, measured by the Löe and Silness gingival index. The explanatory variable was depression, measured by the Patient Health Questionnair. Confounders considered were age, sex, socioeconomic status, frequency of daily tooth brushing, oral hygiene status (measured by the plaque index), consumption of refined carbohydrates in-between meals, use of dental floss, and history of dental service utilization in the past 12 months. A logistic regression model was constructed to determine risk indicators for moderate/severe gingivitis. Additionally, modification of associations between dependent variables and the significant risk indicators of depression was assessed. RESULTS: Mean plaque index for the 1,087 adolescent participants enrolled in the study was 0.80. We found a prevalence of 8.5% for moderate/severe gingivitis and 7.9% for depression. In adjusted regression, there were significant associations between the presence of moderate/severe gingivitis and consumption of refined carbohydrates in-between meals (OR 1.94, 95% CI 1.14, 3.28) and plaque index (OR 16.56, 95% CI 10.03, 27.33). Depression also significantly modified the association between plaque index and the presence of moderate/severe gingivitis (P < 0.0001), with a stronger association observed with mild depression (OR 24.75, 95% CI 3.33, 184.00) compared with no depression (OR 15.47, 95% CI 9.31, 25.69), with no significant modification for the association with frequent consumption of refined carbohydrates (P = 0.06). CONCLUSION: Although there was no significant association between gingivitis and depression among our adolescent Nigerian cohort, depression significantly modified the association between plaque index score and moderate/severe gingivitis.

Associations between a history of sexual abuse and dental anxiety, caries experience and oral hygiene status among adolescents in sub-urban South West Nigeria.

INTRODUCTION: Sexual and oral health are important areas of focus for adolescent wellbeing. We assessed for the prevalence of sexual abuse among adolescents, oral health factors associated with this history, and investigated whether sexual abuse was a risk indicator for dental anxiety, caries experience and poor oral hygiene. METHODS: This was a cross-sectional study conducted between December 2018 and January 2019 among adolescents 10-19 years old in Ile-Ife, Nigeria. Survey data collected included respondents' age, sex, and socioeconomic status, oral health risk factors (dental anxiety, frequency of tooth brushing intake of refined carbohydrates in-between-meals, flossing, dental visits, smoking, alcohol intake, use of psychoactive substances), caries experience, oral hygiene status, history of sexual abuse, and sexual risk behaviors (age of sexual debut, history of transactional sex, last sexual act with or without condom, multiple sex partners). Regression models were constructed to determine the association between outcome variables (dental anxiety, presence of caries experience and poor oral hygiene) and explanatory variables (oral health risk factors and history of sexual abuse). RESULTS: The prevalence of sexual abuse in our cohort was 5.9%: 4.3% among males and 7.9% among females. A history of sexual abuse was associated with alcohol consumption (p = 0.009), cigarette smoking (p = 0.001), and a history of transactional sex (p = 0.01). High/severe dental anxiety was significantly associated with increased odds of a history of sexual abuse (AOR = 1.81; 95% CI 1.10, 2.98), but not with caries experience (AOR = 0.66; 95% CI 0.15, 2.97) nor poor oral hygiene (AOR = 1.68; 95% CI 0.95, 2.96). Dental anxiety was associated with increased odds of alcohol intake (AOR = 1.74; 95% CI 1.19, 2.56), twice daily tooth brushing (AOR = 1.48; 95% CI 1.01, 2.17) and daily consumption of refined carbohydrates in-between-meals (AOR = 2.01; 95% CI 1.60, 2.54). Caries experience was associated with increased odds of using psychoactive substances (AOR = 4.83; 95% CI 1.49, 15.62) and having low socioeconomic status (AOR = 0.40; 95% CI 0.18, 0.92). Poor oral hygiene was associated with increased odds of having middle socioeconomic status (AOR = 1.43; 95% CI 1.05, 1.93) and daily consumption of refined carbohydrates in-between-meals (AOR = 1.38; 95% CI 1.08, 1.78). CONCLUSION: Adolescents who are highly dentally anxious need to be screened for a history of sexual abuse to facilitate access to professional care and support.

Dental caries and its association with the oral microbiomes and HIV in young children-Nigeria (DOMHaIN): a cohort study.

BACKGROUND: This study seeks to understand better the mechanisms underlying the increased risk of caries in HIV-infected school-aged Nigerian children by examining the relationship between the plaque microbiome and perinatal HIV infection and exposure. We also seek to investigate how perinatal HIV infection and exposure impact tooth-specific microbiomes' role on caries disease progression. METHODS: The participants in this study were children aged 4 to 11 years recruited from the University of Benin Teaching Hospital (UBTH), Nigeria, between May to November 2019. Overall, 568 children were enrolled in three groups: 189 HIV-infected (HI), 189 HIV-exposed but uninfected (HEU) and 190 HIV-unexposed and uninfected (HUU) as controls at visit 1 with a 2.99% and 4.90% attrition rate at visit 2 and visit 3 respectively. Data were obtained with standardized questionnaires. Blood samples were collected for HIV, HBV and HCV screening; CD4, CD8 and full blood count analysis; and plasma samples stored for future investigations; oral samples including saliva, buccal swabs, oropharyngeal swab, tongue swab, dental plaque were collected aseptically from participants at different study visits. CONCLUSIONS: Results from the study will provide critical information on how HIV exposure, infection, and treatment, influence the oral microbiome and caries susceptibility in children. By determining the effect on community taxonomic structure and gene expression of dental microbiomes, we will elucidate mechanisms that potentially create a predisposition for developing dental caries. As future plans, the relationship between respiratory tract infections, immune and inflammatory markers with dental caries in perinatal HIV infection and exposure will be investigated.

General anxiety, dental anxiety, digit sucking, caries and oral hygiene status of children resident in a semi-urban population in Nigeria.

BACKGROUND: Digit sucking can represent untreated anxiety or other emotional problems. The aim of this study was to determine if digit sucking is a predictor of general anxiety and dental anxiety; and if general and dental anxiety are associated with caries and oral hygiene status of children resident in sub-urban Nigeria. METHODS: This was a secondary data analysis of a household survey conducted in Ile-Ife, Nigeria. The level of general anxiety and dental anxiety of 450 6 to12 year old children were measured using the Revised Child Manifest Anxiety Scale and Dental Subscale of the Child Fear Survey Schedule respectively. Presence of digit sucking habit, caries and oral hygiene status were determined. General anxiety and dental anxiety scores were dichotomized into low and high levels respectively. Logistic regression was conducted to determine if digit sucking was a predictor of general anxiety and dental anxiety; and if general anxiety and dental anxiety were predictors caries and good oral hygiene status. Adjustments were made for age and sex. RESULTS: Digit sucking is not a significant predictor of dental anxiety (p = 0.99) and general anxiety (p = 0.79). Children with high general anxiety (AOR: 5.02; 95% CI: 2.9-9.74; p <  0.001) and high dental anxiety (AOR: 1.74; 95% CI: 1.15-2.65; p = 0.009) had higher odds of having caries and good oral hygiene respectively. CONCLUSION: Digit sucking was not a significant predictor of general anxiety and dental anxiety. General and dental anxiety however, had effects on the likelihood of having caries and good oral hygiene.

Developmental defects of the enamel and its impact on the oral health quality of life of children resident in Southwest Nigeria.

BACKGROUND: Developmental defects of the enamel (DDE) increase the risk for diseases that impact negatively on the quality of life. The objective of this study was to compare the oral health quality of life of children with molar-incisor-hypomineralisation (MIH) and enamel hypoplasia; and assess if caries worsened the impact of these lesions on the quality of life. METHODS: This study recruited 853 6 to 16-years-old school children. They filled the Child-OIDP questionnaire. The MIH, enamel hypoplasia, caries and oral hygiene status was assessed. Poisson regression was used to determine the impact of MIH and enamel hypoplasia on the oral health quality of life, after adjusting for the effect of sex, age, socioeconomic class, oral hygiene and caries status. RESULTS: The prevalence of MIH and enamel hypoplasia was 2.9% and 7.6% respectively. There was no significant difference in the mean child-OIDP scores of children with or without MIH (p = 0.57), children with or without enamel hypoplasia (p = 0.48), and children with enamel hypoplasia with and without caries (p = 0.30). Children with enamel hypoplasia and caries had worse outcomes for speaking (p = 0.01). Children with middle (AOR: 2.74; 95% CI: 1.60-4.67; P < 0.01) and low (AOR: 1.75; 95% CI: 1.04-2.95; p = 0.03) socioeconomic status, and those with caries (AOR: 2.02; 95% CI: 1.26-3.22; p = 0.03) had their oral health quality of life negatively impacted. CONCLUSION: MIH and enamel hypoplasia had no significant impact on the overall oral health quality of life of children resident in southwestern Nigeria. However, children with caries and those from middle and low socioeconomic classes had poorer oral health quality of life.

Impact of dental caries and its treatment on the quality of life of 12- to 15-year-old adolescents in Benin, Nigeria.

AIM: To assess the impact of caries and its treatment on quality of life (QoL) in 12- to 15-year-old children in Benin, Nigeria. DESIGN: This was a cross-sectional study involving 1790 children. Clinical examinations were conducted using the WHO criteria for diagnosis and coding of caries. The Decayed Missing Filled Teeth score of each child was calculated. The child Oral Impact on Daily Performance questionnaire was used to assess the QoL of children with caries pre- and post-treatment. Associations between age, sex, and socio-economic status and caries were analysed using bivariate and multivariate logistic regression analysis. RESULTS: The prevalence of caries in the study population was 21.9%. Approximately 57% of children with caries reported negative impact on their QoL pre-treatment. Eating (47.6%) was the most affected domain. The mean pre-treatment QoL score was 8.40 ± 10.34. Four weeks post-treatment, only 1.12% of participants reported negative impact of caries treatment on their QoL. The mean post-treatment QoL score was 0.22 ± 0.91 There was a significant difference between pre- and post-treatment QoL scores (P = 0.0001) with significant changes in all the eight domains studied. Age, sex, and socio-economic status had no significant impact on QoL pre- and post-treatment. CONCLUSIONS: Caries had a significant impact on the QoL of adolescents. Its treatment resulted in marked improvement in QoL.

Prevalence, and early childhood caries risk indicators in preschool children in suburban Nigeria.

BACKGROUND: Early Childhood Caries (ECC) is defined as the presence of caries lesion in an primary tooth in children below the age of 71 months. It is a significant public health problem with consequences for the growth and development of affected children. The objective of this study was to determine the prevalence and ECC risk indicators in a suburban population in Nigeria. METHODS: The data of 497 children aged 6 months to 71 months who were recruited through a household survey conducted in Ile-Ife, Nigeria was analysed for prevalence of ECC and risk indicators. Information on children's ages, sex, socioeconomic status, tooth brushing habits, sugary snacks consumption, use of fluoridated toothpaste, birth rank, infant-feeding practices, breastfeeding practices, maternal age at childbirth, and maternal knowledge of oral health was obtained. Children's oral hygiene and caries status was also determined. Risk factors associated with ECC were determined using logistic regression analysis. RESULTS: Thirty-three (6.6%) children had ECC. Four (0.8%) had severe ECC. The four risk indicators for ECC were the child's gender, mothers' knowledge of oral health, consumption of sugary snacks in between meals more than three times a day, and the child's oral hygiene status. Females (PR: -0.06; 95% CI: -0.01- -0.01; p = 0.02), and children with mothers who had good knowledge of oral health (PR: -0.06; 95% CI: -0.11--0.008; p = 0.02) were less likely to have ECC. Children who consumed sugary snacks in between meals three times a day or more (PR: 0.05; CI: 0.003 - 0.01; P = 0.04) and children with fair oral hygiene (PR: 0.05; 95% CI: 0.005-0.10; p = 0.03) were more likely to have ECC. CONCLUSIONS: The prevalence of ECC in the study population was low. Promoting good oral hygiene practices and enhancing mothers' knowledge of oral health may help reduce further, the risk for ECC in the study population.

Appraisal of the national response to the caries epidemic in children in Nigeria.

BACKGROUND: This article reviews the caries profile for children in Nigeria and proposes an appropriate framework for addressing the silent caries epidemic. DISCUSSION: We reviewed the caries prevalence among children in Nigeria, assessed the existing responses to the caries epidemic including the national oral healthcare delivery situation in the country and discussed the current caries management in children. We then proposed a response framework for Nigeria. We argue that successful interventions will require the adoption of a socio-ecological model. This would ensure that the micro-, meso-, exo- and macrosystems required to support the behavioural, structural and biological interventions for promoting caries prevention are addressed. National oral health surveys are required to help understand the epidemiology, social determinants of and factors that undermine the ability of children to access oral health care. A global caries prevention agenda for children would help get the government's support for a national response agenda. Currently, there is no global call for action on the caries epidemic in children. This lack of an agenda needs to be urgently addressed. SUMMARY: A combination of approaches for the prevention of caries in children in Nigeria is needed. A national survey is needed to generate the needed evidence for the planning of community relevant responses to the national caries epidemic in children. The design of a global health agenda for children is an important first step that can facilitate the development of a national oral health programme for children in Nigeria.

The prevalence, pattern and clinical presentation of developmental dental hard-tissue anomalies in children with primary and mix dentition from Ile-Ife, Nigeria.

BACKGROUND: The study of dental anomalies is important because it generates information that is important for both the anthropological and clinical management of patients. The objective of this study is to determine the prevalence and pattern of presentation of dental hard-tissue developmental anomalies in the mix dentition of children residing in Ile-Ife, a suburban region of Nigeria. METHODS: Information on age, sex and socioeconomic status was collected from 1,036 children aged four months to 12 years through a household survey. Clinical examination was conducted to assess the presence of dental anomalies. Associations between age, sex, socioeconomic status, prevalence, and pattern of presentation of the developmental hard-tissue dental anomalies were determined. RESULT: Two hundred and seventy six (26.6%) children had dental anomalies. Of these, 23.8% had one anomaly, 2.5% had two anomalies, and 0.3% had more than two anomalies. Of the children with anomalies, 49.3%were male, 50.7%were female, and 47.8%, 28.6% and 23.6% were children from low, middle and high socioeconomic classes, respectively. More anomalies were seen in permanent than primary dentition. Anomalies of tooth structure were most prevalent (16.1%); anomalies which affect tooth number were least prevalent (1.3%). Dens evaginatus, peg-shaped lateral, macrodontia, and talon cusp were more prevalent in the permanent dentition, and dens evaginatus peg-shaped lateral and macrodontia were more prevalent in the maxilla. There were significantly more macrodontia anomalies in males and in children of high socioeconomic status. CONCLUSION: This large survey of dental hard-tissue anomalies found in the primary dentition and mixed dentition of children in Nigeria provides anthropological and clinical data that may aid the detection and management of dental problems of children in Nigeria.

Programme guidelines for promoting good oral health for children in Nigeria: a position paper.

BACKGROUND: The objective of this paper is to draw attention to the oral health needs of children in Nigeria, and promote the use of appropriate interventions for disease prevention in the population. It also evaluates the value of the ongoing twice-daily tooth brushing campaign, which focuses on promoting good periodontal health and its relevance for children in Nigeria. DISCUSSION: The main oral health burden for children in Nigeria is untreated dental caries, attributable to low utilization of oral health facilities. While there is a strong association between oral hygiene status and caries occurrence, no research had established an association between frequency of tooth brushing and caries in children in Nigeria. Prevalence of caries and gingivitis is low, despite the fact that a majority of children brush once a day and most of them have fair oral hygiene. Campaigns that promote twice daily brushing to prevent chronic periodontitis in children are not driven by evidences supporting the local epidemic, and therefore cannot be considered as efficient use of the limited resources available. SUMMARY: Existing evidences show that the main oral health need of children in Nigeria is the management of untreated caries. Promoting the treatment of caries should be the primary focus of oral health programmes for children in Nigeria, as this would reduce further risks of developing new carious lesions. Public health campaigns should focus efforts at creating demand for oral health care services, for both preventive and curative purposes.

Association between knowledge of caries preventive practices, preventive oral health habits of parents and children and caries experience in children resident in sub-urban Nigeria.

BACKGROUND: The objectives of this study were to assess the association between children and parents' knowledge of caries preventive practices, the parents' caries preventive oral health behaviours and children's caries preventive oral health behaviour and caries experience. METHOD: Three hundred and twenty four participants aged 8-12 years, 308 fathers and 318 mothers were recruited through a household survey conducted in Suburban Nigeria. A questionnaire was administered to generate information on fathers, mothers and children's knowledge of caries prevention measures and their oral health behaviour. Clinical examination was conducted on the children to determine their dmft/DMFT. Analysis was conducted to determine the predictors of the children's good oral health behaviour. RESULT: The mothers' oral health behaviours were significant predictors of the children's oral health behaviours. Children who had good knowledge of caries prevention measures had significant increased odds of brushing their teeth twice daily or more. The children's caries prevalence was 13.9%, the mean dmft was 0.2 and the mean DMFT was 0.09. None of the dependent variables could predict the presence of caries in children. CONCLUSION: The study highlights the effect of maternal oral health behaviour on the oral health behaviour of children aged 8 years to 12 years in suburban Nigeria. A pilot study is needed to evaluate how enhanced maternal preventive oral health practices can improve the oral health preventive practices of children.

Associations between maternal mental health, child dental anxiety, and oral health of 6- to 12-year-olds in Nigeria.

Maternal mental health affects their children's oral health. This study assessed the associations between maternal mental health and dental anxiety level, dental caries experience, oral hygiene, and gingival status among 6- to 12-year-old children in Nigeria. This was a cross-sectional study that recruited mother-child dyad participants through a household survey conducted in Ile-Ife, Nigeria. Data collected included the independent (maternal mental health risk, depressive symptoms, and child's dental anxiety), and dependent (caries experience, oral hygiene status, and gingival health status) variables. Multivariate logistic regression analysis was conducted to determine the associations between dependent and independent variables after adjusting for confounders (mothers' age, child's age, sex, and socioeconomic status). Statistical significance was set at p < 0.05. Of the 1411 mothers recruited, 1248 (88.4%) had low mental health risk, and 896 (63.5%) had mild depressive symptoms. As for the children, 53 (3.8%) had caries, 745 (52.8%) had moderate to high dental anxiety, 953 (63.0%) had gingivitis and 36 (2.6%) had poor oral hygiene. The maternal mental health risk was not significantly associated with the child's caries experience (AOR: 1.012; 95%CI: 0.860-1.190; p = 0.886), poor oral hygiene (AOR:1.037; 95%CI: 0.975-1.104; p=0.250), and moderate/severe gingivitis (AOR:0.887; 95%CI: 0.764-1.030; p = 0.115). Maternal depression status was not significantly associated with the child's caries experience (AOR: 0.910; 95%CI: 0.802-1.033; p = 0.145), poor oral hygiene (AOR: 1.016; 95%CI: 0.976-1.057; p = 0.439), and moderate/severe gingivitis (AOR: 0.963; 95%CI: 0.861-1.077; p = 0.509). Maternal mental health risk and depression do not seem to be risk factors for schoolchildren's oral health in Nigeria. Further studies are needed to understand these findings.

A proposed one-stop-shop approach for the delivery of integrated oral, mental, sexual and reproductive healthcare to adolescents in Nigeria.

The interconnectedness of oral, mental, sexual, and reproductive health (OMSRH) in adolescents prompts exploration of novel approaches to facilitate comprehensive access of this population to the relevant health services. This paper proposes an integrated one-stop-shop approach to increasing adolescents' access to OMSRH care by leveraging on dental clinics as a template for integration, using a non-stigmatized platform to deliver stigmatized healthcare. Novel healthcare delivery models are needed to enhance adolescents' access to the comprehensive prevention and treatment services that they critically need. Effective, integrated health care for this population is lacking, especially across various health areas. This is a proposal for leveraging dental clinics for integrated OMSRH care, using facility-based services, to adolescents. Emphasis will be placed on reducing stigma as a barrier to service accessibility, acceptability, equitability and appropriateness. Empirical studies will be required to test the feasibility, validity and effectiveness of this proposed model.
