BackgroundOne of the goals of the World Health Organisation goal is to ensure increased uptake of preventive oral self-care by 2020. This would require the design public health programmes that will ensure children place premium on preventive oral health care uptake. One effort in that direction is the need for countries to define baseline measures on use of preventive oral self-care measures by their population as well as identify factors that impact on its use. This study aims to determine the prevalence and the impact of age and sex on the use of recommended oral self-care measures by pupils in Southern Nigeria.MethodsPupils age 8 to 16 years (N = 2,676) in two urban sites in Southern Nigeria completed a questionnaire about recommended oral self-care (use of fluoridated toothpaste, flossing, regularity of consuming sugary snacks between main meals), time of the last dental check-up and cigarette smoking habit. Chi square was used to test association between age (8-10years, 11–16 years), sex, and use of recommended oral self-care. Logistic regression analysis was used to determine the predictors of use of recommended oral self-care.ResultsOnly 7.8% of the study population practiced the recommended oral self-care. Older adolescents had an 8.0% increased odds (OR: 1.08; CI:0.81–1.43; p = 0.61) and males had a 20.0% decreased odds (OR: 0.80; CI:0.60-1.06; p = 0.12) of practicing recommended oral self-care though observed differences were not statistically significant. Very few respondents (12.7%) had visited the dental clinic for a check-up in the last one year. Majority of the respondents (92.2%) were non-smokers.ConclusionsThe use of a combination of oral self-care approaches was very low for this study population. Age and sex were predictive factors for the use of components of the oral self-care measures but not significant predictors of use of recommended oral self-care. Future studies would be required to understand ‘why’ and ‘how’ age and sex impacts on the use of caries preventive oral self-care measures to be able to design effective prevention educational programmes for the study population.
BackgroundTo study the association between oral health behaviour of senior dental students in Nigeria and their gender, age, knowledge of preventive care, and attitudes towards preventive dentistry.MethodsQuestionnaires were administered to 179 senior dental students in the six dental schools in Nigeria. The questionnaire obtained information on age, gender, oral self-care, knowledge of preventive dental care and attitudes towards preventive dentistry. Attending a dental clinic for check-up by a dentist or a classmate within the last year was defined as preventive care use. Students who performed oral self-care and attended dental clinic for check-ups were noted to have complied with recommended oral self-care. Chi-square test and binary logistic regression models were used for statistical analyses.ResultsMore male respondents agreed that the use of fluoride toothpaste was more important than the tooth brushing technique for caries prevention (P < 0.001). While the use of dental floss was very low (7.3%), more females were more likely to report using dental floss (p=0.03). Older students were also more likely to comply with recommended oral self-care (p<0.001). In binary regression models, respondents who were younger (p=0.04) and those with higher knowledge of preventive dental care (p=0.008) were more likely to consume sugary snacks less than once a day.ConclusionGender differences in the awareness of the superiority of using fluoridated toothpaste over brushing in caries prevention; and in the use of dental floss were observed. While older students were more likely to comply with recommended oral self-care measures, younger students with good knowledge of preventive dental care were more likely to consume sugary snacks less than once a day.
BackgroundDevelopmental 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.MethodsThis 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.ResultsThe 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.ConclusionMIH 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.
BackgroundStudents’ motives for studying Dentistry have been a subject of interest for years because of the potential for understanding the psychological makeup and subsequent job satisfaction for the dentist. It is also useful in identifying expectations of the profession. This study therefore tried to identify study motives and career preferences of dental students especially with respect to the practice of paediatric dentistry.MethodsThis was a cross-sectional study using a self-administered questionnaire. The final year students in six dental schools in Nigeria were required to fill the questionnaire. Students were asked to rank their motives and career preferences on a Likert like scale with points ranging from 0–5 where 0 represented a factor that had no influence on their decision and 5 represented a very influential factor. The underlying dimensions for study motives, career preference, impression about and motive for interest in the practice of paediatric dentistry were identified using factor analysis.ResultsOne hundred and seventy nine of 223 students (80.3%) participated in this study. Motives for the practice of dentistry included characteristics of the profession, altruism and intellectual challenges, existence of artistic theme in dentistry and parent’s recommendation. Overall, 67.1% of respondents indicated interest in postgraduate studies and 50.8% were interested in paediatric dentistry practice. The main motives for showing interest in the practice of paediatric dentistry were ‘personal interest, professional interest and interest of significant others in children’, and ‘family influence’. Significantly more males than females were interested in the practice of paediatric dentistry though the motives for interest in the practice of paediatric dentistry did not differ significantly by sex or age.ConclusionThe non-significant sex difference in the motives for interest in the practice of paediatric dentistry is a possible reflection of changes in strong cultural themes in the motives for career choices in Nigeria.
The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables-COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60-3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20-0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.
Caries-preventive practice among dental students in Nigeria could be improved. It may be important to explore the possible role of problem-based learning approach in addressing this challenge.
A previous Nigerian study had reported high incidence of periodontal disease in young Nigerians though global studies show the contrary. Aim: To determine the periodontal status and treatment needs of adolescents attending private and public secondary schools in Ibadan, south-western Nigeria. Methods: One thousand, five hundred and twenty two secondary school children in Ibadan were assessed. Sociodemographic data was obtained using a data extraction form. Intraoral examination was performed on all participants. Oral cleanliness was assessed using the plaque index of Silness and Loe, while periodontal health status and treatment needs were assessed using the Community Periodontal Index of Treatment Needs (CPITN). Data were analyzed with the Statistical Package for Social Sciences (SPSS) version 22. Statistical significance was set at p<0.05. Results: Only eight participants (0.5%) had healthy component of periodontal status. The mean plaque index was 1.12±0.41. The CPITN scores varied significantly with the gender of participants (p<0.001). Number of sextants affected by periodontal diseases varied significantly with the socioeconomic status (p=0.02). Conclusions: Gingival ill-health is prevalent among adolescent Nigerians with a great need for oral hygiene instructions and professional cleaning. There is need for oral health education among this sub-population of Nigerian children and provision of mobile dental clinics to help meet their treatment needs.
BackgroundDevelopmental dental hard tissue anomalies are often associated with oral health problems. This study determined the clinical prevalence of developmental dental hard tissue anomalies in the permanent dentition of children resident in southwestern Nigeria and its association with dental caries and poor oral hygiene status.MethodsThis was a cross-sectional study recruiting 1565 school children, 12 to 15 year old attending schools in Ibadan, Oyo State and Ile-Ife, Osun State. All eligible study participants had oral examinations conducted to determine presence of developmental hard dental tissue anomalies, caries and oral hygiene status. The prevalence of developmental dental hard tissue anomalies was determined. Logistic Poisson regression was used to determine the association of between developmental dental hard tissue anomalies, caries and oral hygiene status.ResultsOnly 65 (4.2 %) children had clinically diagnosed developmental dental hard tissue anomalies. The most prevalent anomaly was enamel hypoplasia (2.2 %). More females (p = 0.003) and more children with middle socioeconomic class (p = 0.001) had enamel hypoplasia. The probability of having poor oral hygiene was significantly increased for children with developmental dental anomalies (APR: 0.07; 95 % CI: 0.03 – 0.12; p = 0.002). The probability of having caries was insignificantly increased for children with developmental dental hard tissue anomalies (APR: 0.005; 95 % CI: −0.03 – 0.04; p = 0.08).ConclusionThe most prevalence clinically detectable developmental dental hard tissue anomalies for the study population was enamel hypoplasia. The presence of developmental dental hard tissue anomalies significantly increased the chances of having poor oral hygiene but not caries. Further studies are required to understand if poor oral hygiene is associated with dental caries in children with developmental dental hard tissue anomalies.
