A Community Survey on Association of Sociodemographic Characteristics with Risk Perception and Awareness about Oral Cancer in Lagos, Nigeria

ABSTRACT Objective: To assess the level of oral cancer awareness and risk factors perception and the relationship between this awareness and the sociodemographic and behavioral characteristics. Material and Methods: This descriptive study was conducted among rural and urban residents in Lagos State, Nigeria. A multi-stage random sampling method was utilized. The sociodemographic and behavioral characteristics of respondents, as well as their knowledge about oral cancer risk factors, were assessed with a validated questionnaire. The bivariate association was done using an independent t-test and one-way ANOVA. Multivariate regression was used to determine the association between predictor variables and oral cancer knowledge scores. The statistical significance level is set at p<0.05. Results: 590 participants between 18 and 82 years (mean age 34.5 ±13.7) completed the survey. The prevalence of cigarette smoking was 25.7%, of which 16 (1.5%) were heavy smokers (20+ cigarettes per day). The prevalence of alcohol consumption was 66.1%, with 57 (9.7%) being heavy drinkers, consuming drinks for 5-7 days of the week. A high proportion of the respondents (>60%) exhibited gaps in their knowledge of oral cancer. Uneducated participants had lower oral cancer knowledge than those with >12 years of formal education (aOR = 5.347; 95% CI: 4.987-6.240). Participants who were smokers had lower oral cancer knowledge compared with non-smokers (aOR = 3.341; 95% CI: 2.147-4.783); Participants who consumed alcohol had more deficient oral cancer knowledge compared with non-drinkers (aOR = 1.699; 95% CI: 1.087-2.655); While heavy smokers aOR = 4.023; 95% CI: 3.615-4.825) and heavy drinkers aOR = 4.331; 95% CI: 3.158-5.939) had lower oral cancer knowledge compared with those who did not abuse both substances. Conclusion: A high proportion of the respondents exhibited gaps in their knowledge of oral cancer in their responses. Delayed diagnosis of oral cancer can be reduced by increasing the awareness and knowledge of the populace about risk factors and also in the recognition of its signs and symptoms.

Awareness and Preferred Mode of Getting Information on First Aid Management of Avulsed Permanent Teeth: Survey of Nigerian Mothers

ABSTRACT Objective: To determine the awareness and sources of information on first aid management of avulsed permanent teeth in a group of South-western Nigerian mothers. Material and Methods: An 18-item interviewer-administered questionnaire was used to survey 385 mothers attending the antenatal and immunization clinics on their perception towards dental avulsion, its management, sources, and preferred mode of receiving information on first aid. The effect of all significant factors was inferred at p<0.05. Results: Mothers who had previous information on the first aid management of dental avulsion had significantly higher knowledge (p=0.000). Majority (80.8%) of the mothers did not know that an avulsed permanent tooth could be replanted, though mothers whose children had not experienced dental trauma had significantly higher knowledge (p=0.003). The knowledge of first aid management of avulsed permanent tooth was low, regardless of age, education and employment status of the respondents. Conclusion: There was low knowledge among mothers regarding the first aid measures in the management of avulsed permanent teeth. Their main preference for receiving information was through social media and television. There is a need to increase oral health educational campaigns targeted towards mothers.

Disparities in Caries Experience and Socio-Behavioural Risk Indicators Among Private School Children in Lagos, Nigeria

Abstract Objective: To determine the prevalence and socio-behavioural risk factors for dental caries among children at selected LGAs in Lagos State. Material and Methods: This was a descriptive study of 592 school children in four Local Government Areas of Lagos, Nigeria. The presence of caries was recorded using the World Health Organization criteria. Descriptive statistics were reported for analysis of comparative DMFT and SiC scores in relation to age, gender, and other socio-demographic variables. Logistic regression analysis was used to analyze the differential impact of the variables on the probability of being in the high caries prevalence group. Results: The prevalence of dental caries was 16.0% with mean dmft for age 6 being 1.3 ± 1.57 while the mean DMFT for age 12 was 0.15 ± 0.67. The mean Sic for age 6 was 1.5 ± 0.53 while the mean SiC for age 12 was 1.09 ± 0.29. The mean SiC values was significantly higher in the primary and permanent dentition among those who had never visited the dentist, female students, those who don't use fluoridated toothpaste and those who eat sweets and candy several times a day. After logistic regression analysis, those with no previous dental visit (OR=3.05; CI: 1.72-4.67) and females (OR=1.55; CI: 1.16-1.62) still had significantly higher SiC Values. Conclusion: The prevalence of caries was low in the study population. Being female, non-use of fluoride-containing toothpaste and not visiting the dentist were significant predictors of dental caries among children attending private schools.

Association between dental caries, odontogenic infections, oral hygiene status and anthropometric measurements of children in Lagos, Nigeria

Dental caries is a significant public health problem afflicting about a third of the world's population which impacts nutrition, quality of life and systemic health. Aim: We explored associations between dental caries, odontogenic infections, oral hygiene and anthropometric measurements of children in Lagos, Nigeria. Methods: A pretested validated questionnaire was administered on 278 children who also received anthropometric assessment and dental examinations. Caries was scored according to WHO criteria and untreated dental caries by the Pulpal Exposure, Ulceration, Fistula, Abcess (PUFA/pufa) index. The weight for age (WAZ), height for age (HAZ), and weight for height (WHZ) parameters evaluated nutritional status. Categorical and continuous data were analysed by χ2-test and ANOVA. Regression analysis was done and statistical significance set at p ≤ 0.05. Results: The prevalence of Decayed, Missing, and Filled Teeth (DMFT + dmft) > 0 was 220 (79.1%) and the proportion of d+D teeth in dmft+DMFT index was 194 (70.0%). The prevalence of odontogenic infections due to caries (PUFA + pufa > 0) was 172 (61.8%). 74 (26.6%) children were stunted; 12 (4.3%) were underweight while 30 (10.8%) were wasted. Children with PUFA + pufa > 1 had increased risk of wasting (OR: 2.45; 95% CI: 1.16-4.88). Children with DMFT+dmft >5 were also significantly underweight with odds ratios of 2.34 (95% CI 1.04-4.33). Conclusions: There was significant association between untreated dental caries, odontogenic infections and stunting, wasting and being underweight among the children studied. Policy makers should be aware of the additional burden that oral neglect has on anthropometric indices

Predictors of Postgraduate Dental Specialty Training Choice: The Nigerian Experience.

Objectives: The objectives of this study are three-fold. First, to highlight areas of shortage in postgraduate dental education in Nigeria, secondly to propose the introduction of dental advisors into our postgraduate dental training and thirdly, to propose a model that could aid such dental advisors in predicting postgraduate dental training choice among Nigerian dental graduates. It is hoped that such a model would have enough predictive powers to aid would-be dental advisors in guiding fresh dental graduates aright in their choice of postgraduate dental training. Methods: Participants were dentists attending compulsory continuing professional development events at different centres across Nigeria. Graded Likert responses of 16 potential predictors of dental postgraduate training choice were obtained through self-administered questionnaires filled by 112 Nigerian dentists (mean age of 35.21 years ± 8.21). Data were analyzed after necessary recodes to allow for meaningful statistical analysis. The predictive power of each factor was determined by inter-specialty and intra-specialty comparisons. Results: A total of 51 males and 61 females participated in the study with predictors rated from 2.29 ± 1.23 to 4.09 ± 1.04. Diagnostic challenge strongly predicted a choice of Oral and maxillofacial surgery. Affluence and income jointly predicted choices of orthodontics and restorative dentistry while the female gender predicted a choice of pediatric dentistry. (P=<0.001). Work-life balance influenced a choice of preventive dentistry-related specialties in combination with other factors. Periodontology had several unique predictors. Conclusions: Income, work hours, private practice opportunity and affluence were stronger predictors than skills and course content in this study. There's a gradual shift from an oral surgery predilection to restorative dentistry. A female predilection for pediatric dentistry and male predilection for oral surgery persist. Endangered specialties like periodontics, prosthodontics justify a call office of postgraduate dental advisors in Nigerian postgraduate dental training to avert the looming dental training manpower crisis.
