    Clinical and sociodemographic factors associated with oral health knowledge, attitude, and practices of adolescents in Nigeria
    (2020) Lawal, F. B.; Oke, G. A
    The institution of appropriate oral health promotion programs targeted at adolescents in schools in developing countries requires baseline information on their oral health knowledge, attitude, and practices as well as associated factors influencing it, which are unknown. This study assessed clinical and sociodemographic factors associated with oral health knowledge, attitude, and practices of adolescents in Ibadan, Nigeria. Two-thousand and ninety-seven students aged 12-18 years were recruited from 30 randomly selected secondary schools in a cross-sectional study conducted in Ibadan, Nigeria. Data were obtained through a questionnaire on oral health knowledge, attitude, and practices, and sociodemographic characteristics. Oral examination was conducted to assess the clinical oral condition of the adolescents. Data were analyzed with SPSS. The higher the percentage scores, the better the oral health knowledge, attitude, and practices, and overall awareness of oral health. The oral health knowledge score ranged from 0% to 60%; mean oral health knowledge score was 15.1% (±6.6%). The oral health attitude score ranged from 0% to 91.3%; mean oral health attitude score was 44.5% (± 14.3%). The oral health practices score ranged from 0% to 88.9%, and mean oral health practices score was 42.5% (± 13.8%). The mean oral health knowledge, attitude, and practices score was 43.8% (± 11.4%). A total of 1537 (73.3%) participants had unhealthy periodontium and 98 (4.7%) had dental caries. Students who were 12-15 years (odds ratio = 1.7, 95% confidence interval = 1.42.0, p < 0.001), females (odds ratio = 1.2, 95% confidence interval = I.0-I.5, p = 0.024), offspring of skilled workers (odds ratio = 1.5, 95% confidence interval = I.I-2.0, p = 0.010), previously educated about oral health (odds ratio = 1.3, 95% confidence interval = I.0-I.7, p = 0.023), consulted the dentist (odds ratio = 1.9, 95% confidence interval = I.2-3.I, p = 0.009), or had unhealthy periodontal condition (odds ratio = I.2, 95% confidence interval = I.0-I.5, p = 0.042) were more likely to have higher oral health knowledge, attitude, and practices scores or awareness than others. Better knowledge, attitude, and practices score was associated with younger age group, higher occupational class, previous oral health education, dental consultation, and having unhealthy periodontal condition

    Effectiveness of an Oral Health Education Program to Improve Mothers’ Awareness of Natal Teeth: A Randomized Controlled Study
    (2020) Bankole, O,O.; Lawal, F.B
    To evaluate the effectiveness of an oral health talk aided by a video on improving the awareness of mothers about natal teeth in two rural communities in southwest Nigeria. A cluster randomized controlled trial was conducted among 80 mothers in two rural communities in Nigeria, randomized into study and control groups. Baseline information was obtained with a pre-tested interviewer administered questionnaire. The mothers in the study group participated in an oral health education program comprising of a video show on natal teeth in addition to an oral health talk. The control group did not receive any intervention. Post-intervention data was obtained three weeks afterwards. Data collected was analyzed with SPSS using paired t-test, independent t-test and Chi-square test. The sociodemographic characteristics of participants in both groups were similar. The mean knowledge, attitude and practice percentage scores for the study group were 38.9 ± 26.3% (pre-intervention) and 73.6 ± 26.2% (post-intervention); while for the control group, the values were 43.2 ± 31.4% (pre-intervention) and 43.9 ± 32.4% (post intervention). The study group, had a 34% increase in knowledge, attitude and practice percentage score (CI=23.7-45.5; t=6.4; p<0.001), while the control group, had an increase of 0.7% (CI=-0.7- 2.2; t=1.00; p=0.323). An oral health education program comprising of oral health talk and a video about natal teeth improved the awareness of mothers about natal teeth as a normal phenomenon

    Knowledge of School-Going Adolescents About the Oral Effects of Tobacco Usage in Ibadan, Southwest Nigeria
    (2020) Lawal, F.B.; Fagbule, O.F.
    The individual knowledge of the effects of tobacco usage on health plays an important role in its uptake. Tobacco consumption usually starts during adolescence, and lack of knowledge about the oral problems of tobacco usage probably plays a role in it. To determine the knowledge of adolescents about the effect of tobacco usage on oral health. A cross-sectional study was conducted among 1,465 adolescents aged 12 to 20 years who attended senior secondary schools in a major city in Nigeria. Data were obtained through a semistructured questionnaire. Data obtained were analyzed with SPSS. The mean age of respondents was 15.2 (_1.4) years. Only 40 (2.7%) of them used tobacco at the time of study and 992 (67.7%) said that tobacco usage has effect(s) on oral health. The main effects mentioned were mouth odor: 338 (34.1%); teethdiscoloration: 297 (29.9%); tooth decay: 138 (13.9%); damage to teeth: 72 (7.3%); lip discoloration: 39 (3.9%); and oral cancer: 11 (1.1%). It was found that female respondents (72.1%, odds ratio¼1.4, confidence interval¼1.1–1.7, p¼.005); those aged 12 to 15 years (73.6%, odds ratio¼2.0, confidence interval¼1.6–2.5, p<.001); and children of skilled workers (73.4%, odds ratio¼1.9, confidence interval¼1.2–3.0, p¼.008) were more likely to mention that tobacco has adverse effect(s) on oral health. Although two thirds of the students knew that tobacco usage has effects on oral health, there were gross inadequaciesin the knowledge and misconceptions about those effects

    To determine the psychometric properties of the General Oral Health Assessment Index (GOHAI) in a sample of adult rural dwellers in Southwestern Nigeria
    (2020) Lawal, F.B
    This cross-sectional study was conducted among 395 adults attending dental outreach programs in Igboora, Nigeria. A translated interviewer administered questionnaire comprising socio demographic characteristics, GOHAI questions, self-rating of oral health and satisfaction with dental appearance was used to obtain data. Oral examination was also performed. The data obtained was analyzed for reliability and validity of GOHAI using SPSS and p value was set at <0.05%. The GOHAI score of respondents ranged from 5 to 60. Many 283 (71.6%) reported at least an impact of oral condition on quality of life (OHRQoL). The most reported impairment was the use of medication to relieve pain (221, 55.9%). GOHAI demonstrated excellent internal consistency with a Cronbach alpha of 0.97. Principal component analysis resulted in extraction of one factor; Kaiser-Meyer-Olkin measure was 0.96 and Bartlett’s test was significant (p<0.001). GOHAI was able to discriminate between those with periodontal treatment needs (p<0.001), missing teeth (p<0.001) or decayed teeth (p=0.001) and those without those oral findings. Higher GOHAI scores (less impact on OHRQoL) correlated negatively with poor selfrating of oral health (rs = -0.72, p<0.001) and dissatisfaction with dental appearance (rs = -0.70, p<0.001). More males (p=0.012) and divorced respondents (p=0.016) reported impacts on OHRQoL than others. GOHAI has acceptable psychometric properties and validity among underserved adults living in a rural Nigerian community
