Knowledge of Oral Prophylaxis and Dental Check-up Amongst Primary School Teachers in Lagos State: An Urban-rural Comparative Study: Dental Public Health

ABSTRACT Background: Oral health knowledge of school teachers will influence the success of the strategy of the National Oral Health Policy at the Community level. Aim: This study aimed to assess and compare the oral health knowledge in Urban and Rural areas of Lagos State. Methodology: A cross-sectional study, using a multistage sampling technique to select 200 primary school teachers in both urban and rural areas. A pretested, self-administered questionnaire was used. Data was analysed using SPSS version 20. Descriptive and crude odd ratio were used, and p-value ⩽0.05 is significant. Result: The mean age of the respondent is 39±10.92 and 47±7.56 for rural and urban areas respectively. More teachers were females in rural and urban areas. The ever-married were majority in both rural and urban areas. Majority had National Certificate of Education in rural and urban areas.  Urban teachers [55%] had adequate oral health knowledge and 63% in the rural had inadequate oral health knowledge.  Crude odd ratio revealed a significant association between geographical location and oral health knowledge [p=0.0102; OR=2.081]; marital status [p=0.0204; OR=0.26] and teaching experience [p=0.0442; ≤10years, OR=1.533; ≤15years, OR=2.130 and ˃16years, OR=3.179].  Conclusion: Primary school teachers in urban area showed adequate oral health knowledge than their counterparts in the rural area of Lagos State

`PATTERN OF HISTOLOGIC VARIANTS OF AMELOBLASTOMA IN A SECONDARY HEALTH CARE FACILITY IN LAGOS STATE: A 5-YEAR RETROSPECTIVE STUDY.

Background: Ameloblastoma is a benign epithelial odontogenic neoplasm which is common amongst the Yoruba ethinc group. The various histologic types have been elucidated. Aim: This study aimed to assess the prevalent histologic types of ameloblastoma in a Lagos secondary health care facility. Methodology: A 5-year retrospective review of histopathologically diagnosed slides were retrieved. Data extracted include the age, gender, location, ethnicity and histologic variants were analysed by SPSS version 26. Percentages, ratio, mean, standard deviation and crude odd ratio were determined, and p-value ⩽ 0.05 is considered significant. Result: A total of seventy-seven histopathologically diagnosed ameloblastoma slides were retrieved. Males were more affected than females in ratio 1.2:1 with the mean age 33.61±13.3. Ameloblastoma was commonest in the third decade of life and more in the mandible than maxilla. Yoruba ethnic group was most affected. The commonest histologic type was the unicystic type with intraluminal subtype accounting for the largest proportion. There was significant association between histologic types and gender (p= 0.037). Crude odd ratio revealed the odds in the unicystic type between male and female {p=0.041; CI=95%, OR=2.649(1.042-6.733)} and in the follicular between male and female {p=0.013; CI=95%, OR=3.855(1.321-11.288)}. Conclusion: The unicystic histologic type of ameloblastoma was the commonest, occurring more in females and this was followed by the follicular histologic type which occurred more in males in this Lagos State secondary health care facility
