Pattern and prevalence of dental anomalies among a paediatric population in Lagos, Nigeria.

Background: Dental anomalies are craniofacial abnormalities in the size, structure or number of the teeth. This study was conducted to assess the prevalence of dental anomalies among children aged 0-16 years attending the Paediatric Dental Clinic at the Lagos University Teaching Hospital, Lagos, Nigeria. Methods: A cross-sectional design was used and data were obtained from the dental records of the Dental Clinic from January 2014 to August 2019 by two calibrated examiners, who are co-authors of the manuscript. To test for statistical differences, Chi-squared test was utilised for the categorical variables. The prevalence of the different dental anomalies was estimated and presented with frequencies. P < 0.05 was considered statistically significant. Results: Among the 6175 patients' dental records reviewed, 50.85% (n = 3150) were male and the highest proportion of 45.4% (n = 2807) were aged between 6 and 10 years, with a mean age of 8.62 ± 3.85 years. A total of 1090 (17.52%) had dental anomalies; 465 (7.53) anomalies were in the maxilla, 263 (4.6) were in the mandible while 360 (5.83) were in both. The most common anomaly was hypoplasia 550 (9.06%), followed by retained primary tooth 546 (8.84%) and hypodontia 84 (1.36%). Dentinogenesis imperfecta 1 (0.02) and transposition 1 (0.02) were the least prevalent anomalies. Retained primary teeth (5.8%) and the cusp of Carabelli (0.4%) were slightly more prevalent among males. However, females had a higher prevalence of natal/neonatal teeth (0.4%), fusion/germination (0.4%), hypodontia (1.5%) and peg-shaped lateral incisors (0.9%). Conclusion: Dental anomalies' prevalence in this study was 17.52%, with a higher occurrence of anomalies in the maxilla. Hypoplasia was the most prevalent anomaly, after which was retained primary tooth, then hypodontia. Prompt diagnosis and preventive interventions are crucial for the appropriate management of these dental anomalies.

Replication of GWAS significant loci in a sub-Saharan African Cohort with early childhood caries: a pilot study.

BACKGROUND: Early childhood caries (ECC) is a rapidly progressing form of dental infection and a significant public health problem, especially among socially and economically disadvantaged populations. This study aimed to assess the risk factors for ECC among a cohort of Sub-Saharan African children and to determine the role of genetics in the etiology of ECC. METHODS: A sample of 691 children (338 with ECC, 353 without ECC, age < 6 years) was recruited from schools in Lagos, Nigeria. Socio-demographic, dental services utilization and infant dietary data were obtained with interviewer-administered questionnaire. Oral examination was conducted using the WHO oral health diagnostic criteria. Saliva samples were collected from the children for genetic analysis. Single nucleotide polymorphisms were selected from previous study for genotyping. Genetic association analyses to investigate the role of genetics in the etiology of ECC was done. Bivariate comparisons and Multivariate logistic regression analyses were conducted to assess associations between ECC and predictor variables, p < 0.05. RESULTS: Of the 338 children with ECC, 64 (18.9%) had Severe-Early Childhood Caries (S-ECC). Children aged 48-59 months comprised the highest proportion of subjects with ECC (165; 48.8%) and S-ECC (24; 37.5%) while female subjects had higher dt (3.13 ± 2.56) and dmft values 3.27 ± 2.64. ECC was significantly more prevalent among children who were breastfed at night ≥ 12 months (OR 3.30; CI 0.39, 4.75), those with no previous dental visit (OR 1.71; CI 0.24, 2.77), those who used sweetened pacifiers (OR 1.85; CI 0.91, 3.79) and those who daily consumed sugar-sweetened drinks/snacks (OR 1.35; CI 0.09, 18.51). A suggestive increased risk for ECC (OR 1.26, p = 0. 0.0397) was observed for the genetic variant rs11239282 on chromosome 10. We also observed a suggestive reduced risk for ECC (OR 0.80, p = 0.03) for the rs131777 on chromosome 22. None of the genetic variants were significant after correction for multiple testing (Bonferroni p value p = 0.004). CONCLUSIONS: Prolonged night-time breastfeeding, poor utilization of dental services and daily consumption of sugar were risk factors for ECC. Larger sample size is needed to confirm the results of the genetic analysis and to conduct genome wide studies in order to discover new risk loci for ECC.

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.

An investigation of data from the first year of the interim Canada Dental Benefit for children <12 years of age.

Introduction: In 2022, the federal government announced a commitment of $5.3B to provide dental care for the uninsured, beginning with children <12 years of age. Now referred to as the Interim Canada Dental Benefit (CDB), the program targets those <12 years of age from families with annual incomes <$90,000 without private dental insurance. The purpose of this study was to review federal data from the Government of Canada on public uptake and applications made to the Canada Revenue Agency (CRA) during the first year of the Interim CDB. Methods: Data for the first year of the Interim CDB (up to June 30, 2023) were accessed from the Government of Canada Open Data Portal through Open Government Licence-Canada. Rates of children receiving the Interim CDB per 1,000 were calculated by dividing the number of beneficiaries by the total number of children 0-11 years by province or territory, available from Statistics Canada for the year 2021. Results: During the first year of the program, a total of 204,270 applications were approved, which were made by 188,510 unique applicants for 321,000 children <12 years of age. Over $197M was distributed by the CRA. Overall, the national rate for receiving the Interim CDB was 67.8/1,000 children. Ontario (82.5/1,000), Manitoba (77.1/1,000), Nova Scotia (73.4/1,000), and Saskatchewan (72.3%), all had rates of children with the Interim CDB above the national rate. Conclusions: Data from the first year of the Interim CDB suggests that this federal funding is increasing access to care for children <12 years by addressing the affordability of dental care. Governments and the oral health professions need to address other dimensions of access to care including accessibility, availability, accommodation, awareness, and acceptability of oral health care.

Canadian dentists' awareness and views on early childhood caries and its prevention and management.

Introduction: The Canadian Dental Association (CDA) recommends children visit a dentist within 6 months of the eruption of their first tooth or by 12 months of age. The aim of this study was to investigate Canadian dentists' awareness and views on early childhood caries (ECC) and its prevention and management. Methods: This study analyzed a subset of questions relating to dentists' knowledge of ECC and prevention strategies, from a national survey of general and pediatric dentists, commissioned by the CDA in 2013. Analyses included descriptive, bivariate, and multivariate analyses. A p-value of ≤0.05 was considered significant. Results: Three thousand two hundred thirty-two out of 14,747 dentists responded (response rate of 21.9%), with 95.1% having heard of ECC. Overall, 60.9% of respondents reported that they were comfortable providing treatment to children with ECC. Significant differences were found between the number of years in practice and whether dentists were or were not comfortable providing prevention (19.5 ± 12.6 years vs. 25.4 ± 12.1 years; p < 0.001) or treatment for patients with ECC (19.1 ± 12.7 years vs. 22.5 ± 12.3 years; p < 0.001). Pediatric dentists (OR = 6.92; 95% CI: 2.57, 18.61), female dentists (OR = 1.13; 95% CI: 1.03, 1.24), dentists practicing in smaller urban areas (OR = 1.17; 95% CI: 1.07, 1.28), and dentists who were aware of the CDA's position on ECC (OR = 1.26; 95% CI: 1.13, 1.41) were more likely to be comfortable providing treatment for children with ECC. Conclusions: While the majority of Canadian dentists have sufficient knowledge of ECC, not all are comfortable providing oral health care services to children at a young age. It is encouraging however, that most dentists are wanting additional oral health resources designed for education on ECC prevention for parents of young children.

Children's Oral Health Initiative: workers' perspectives on its impact in First Nations communities. / Initiative en santé buccodentaire des enfants : le point de vue des intervenants quant à ses effets dans les communautés des Premières Nations.

INTRODUCTION: Since 2004, the Children's Oral Health Initiative (COHI) has been working in many First Nations and Inuit communities in Canada to address oral health disparities, specifically early childhood caries (ECC). The COHI community-based approach improves early childhood oral health (ECOH) by balancing prevention with minimally invasive dentistry. The goal is to reduce the burden of oral disease, mainly by minimizing the need for surgery. We investigated program success in First Nations communities in the province of Manitoba, from the perspective of COHI staff. METHODS: First Nations community-based dental therapists and dental worker aides participated in three focus groups and an in-depth semistructured interview. The collected data were thematically analyzed. RESULTS: Data from 22 participants yielded converging and practitioner-specific themes. Participants reported that dental therapists and dental worker aides provide access to basic oral care in their communities including oral health assessments, teeth cleaning, fluoride varnish applications and sealants. The participants agreed that education, information sharing and culturally appropriate parental engagement are crucial for continuous support and capacity building in the community programs. Low enrolment, difficulty accessing homes and getting consent, limited human resources as well as lack of educational opportunities for dental worker aides were identified challenges. CONCLUSION: Overall, the participants reported that the COHI program positively contributes to ECOH in First Nations communities. However, increased community-based training for dental workers, community awareness about the program, and engagement of parents to facilitate culturally appropriate programming and consent processes are critical to improving program outcomes.

A Preexperimental Study to Assess the Impact of an Interdisciplinary Educational Intervention on Nurses' Knowledge of Perinatal and Infant Oral Health Care.

OBJECTIVE: The objective of this study was to assess the impact of an interdisciplinary educational intervention on the knowledge of nursing practitioners regarding perinatal and infant oral health (PIOH) care. MATERIALS AND METHODS: This was a preexperimental study conducted among nursing practitioners in Lagos, Nigeria. Participants received hands-on training and didactic lectures, which included dental caries etiology and risk factors; oral hygiene and dietary education; teething and its management; dental trauma and its prevention; nonnutritive habits; screening, referrals, and counseling; and fluoride varnish application. Knowledge of the trainees was assessed using pre- and posttest questionnaires. Level of statistical significance was set at P < 0.05. RESULTS: Overall, 110 nurses participated in the study with a mean age of 40.9 ± 10.8 years; 106 (96.4%) were females. Approximately 88% of the participants had not received formal training on PIOH. The baseline mean scores of the participants' knowledge on oral hygiene, teething, trauma, caries, and oral habits were 4.31 ± 1.9, 9.84 ± 2.6, 2.59 ± 1.7, 4.24 ± 1.8, and 1.45 ± 0.6, respectively; this increased significantly (P < 0.001) following the educational intervention with posttest mean scores as 7.58 ± 0.8, 11.79 ± 1.3, 4.34 ± 1.9, 6.19 ± 1.8, and 1.82 ± 0.4 and six-month evaluation scores as 6.21 ± 1.8,7 10.27 ± 3.1, 4.39 ± 1.5, 5.91 ± 1.8, and 1.79 ± 0.5, respectively. Overall posttest (31.4 ± 4.2) and six-month (28.6 ± 6.2) knowledge scores were significantly higher than the pretest values (22.4 ± 4.8, P < 0.001). At the six-month post-intervention survey, 84% of the nurses reported inclusion of PIOH education in their routine general health education sessions. CONCLUSION: There was a positive impact of the educational intervention as evidenced by an increase in the knowledge of the nurses on PIOH care and the inclusion of PIOH education in their general health education. A slight decline between posttest and six-month evaluation scores indicates a need for continuous education and evaluation.
