One 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.

COVID-19 infection is associated with oral lesions which may be exacerbated by tobacco smoking or e-cigarette use. This study assessed the oral lesions associated with the use of e-cigarettes, tobacco smoking, and COVID-19 among adolescents and young people in Nigeria. A national survey recruited 11–23-year-old participants from the 36 States of Nigeria and the Federal Capital Territory, Abuja. Data were collected using Survey Monkey^®. Binary logistic regression analysis was conducted. Statistical significance was set at p-value less than 0.05. There were 2870 participants, of which 386 (13.4%) were tobacco smokers, 167 (5.8%) e-cigarette users, and 401 (14.0%) were both e-cigarette and tobacco users; and 344 (12.0%) had ever tested positive to COVID-19. Adolescents and young people who smoked tobacco had more than twice the odds of reporting gingival inflammation, oral ulcers, dry mouth, and changes in taste than those who did not smoke. Those who used e-cigarettes had 1.5 times higher odds of reporting oral lesions. Respondents who had COVID-19 infection had higher odds of reporting gingival inflammation and lower odds of reporting dry mouth than those who did not have COVID-19 infection. These findings were significant, and may help clinicians to screen for tobacco use and COVID-19 among adolescents and young people in Nigeria.

Background: The impact of the COVID-19 pandemic on the world is unprecedented, posing greater threats to vulnerable healthcare systems, especially in developing countries. This study aimed to assess the knowledge of dental healthcare providers in Nigeria about the disease and evaluate their responses to the preventive measures necessitated by COVID-19.Methods: This was an online self-administered questionnaire-based study conducted among dentists practicing in Nigeria. A message containing the link to the survey was sent widely via social medial platforms and electronic mails to dentists practicing in Nigeria. The data collection was done between the 2^ndof June and 3rd of July 2020.Results: A total of 314 responses was recorded. Fever was the most specified generalized symptom (97.5%), while the use of masks (100%), hand hygiene (99.7%), social distancing (97.7%) and surface cleaning (99.4%) were the most commonly employed general preventive methods. The main identified risk of transmission in the clinic was aerosol generating procedures (98.7%).Conclusion: The general knowledge of dental personnel in our study population appears to be adequate on the common clinical features of COVID-19 but less adequate regarding the less common features. The COVID-19 pandemic has also modified some aspects of dental service delivery but more needs to be done in this regard. Preventive measures against the transmission of COVID-19 in dental practice settings include proper utilization of teledentistry, clinical triage, preprocedural 1% hydrogen peroxide oral rinses, and the use of appropriate Personal Protective Equipment (PPE) which should always be encouraged.

This study aimed to assess the proportion of adolescents and young people (AYP) in Nigeria who changed their frequency of e-cigarette use and tobacco smoking during the COVID-19 pandemic; and factors associated with the increase, decrease or no change in e-cigarette use and tobacco smoking (including night smoking). This study was a cross-sectional study of AYP recruited from all geopolitical zones in the country. Multivariate logistic regression analyses were conducted to determine if respondents’ health HIV and COVID-19 status and anxiety levels were associated with changes in e-cigarette use and tobacco smoking frequency. There were 568 (59.5%) e-cigarette users, of which 188 (33.1%) increased and 70 (12.3%) decreased e-cigarette use and 389 (68.5%) increased night e-cigarette use. There were 787 (82.4%) current tobacco smokers, of which 305 (38.8%) increased and 102 (13.0%) decreased tobacco smoking and 534 (67.9%) increased night tobacco smoking. Having a medical condition was associated with lower odds of increased e-cigarette use (AOR:0.649; p = 0.031). High anxiety (AOR:0.437; p = 0.027) and having a medical condition (AOR:0.554; p = 0.044) were associated with lower odds of decreased e-cigarette use. Having COVID-19 symptoms (AOR:2.108; p < 0.001) and moderate anxiety (AOR:2.138; p = 0.006) were associated with higher odds of increased night e-cigarette use. We found complex relationships between having a medical condition, experiencing anxiety, changes in tobacco smoking and e-cigarette use among AYP in Nigeria during the COVID-19 pandemic that need to be studied further.

Early childhood caries (ECC) is a significant oral health issue affecting children under six years old. This study aimed to determine the prevalence and di

Anterior dental trauma is known to be common in our environment as well as the complications that come with it. These injuries have been seen to impact the quality of life (QoL) of children significantly due to the fact that they compromise their dental health. This leads to aesthetic, psychological, social, and therapeutic problems impacting both the children and their parents. Treatment of these injuries has also been severely neglected possibly due to lack of awareness of where or how to access treatment as well as fear of dental treatment. However, treatment may on the other hand bring about a substantial improvement on the QoL of children in terms of their daily living. To assess the effect of dental treatment on the QoL of 12- to 15-year-old Nigerian school children previously identified as having had traumatized anterior teeth. This is a follow-up study where secondary data were extracted from a cross-sectional study involving 1575 children attending public and private secondary schools in Ibadan, Nigeria. One hundred and ninety-six adolescents with evidence of dental trauma, previously identified as having their QoL negatively affected as a result of dental trauma, were called to take part in the follow-up study. The Child Perception Questionnaire (CPQ_11-14) was used in assessing the QoL of participants with dental trauma before and after treatment. Data were analysed using the IBM^® SPSS^® Statistics version 20.0, and the effect of dental treatment on the QoL of the participants was assessed using the McNemar's test. Statistical significance was set at P < 0.05. Fifty-one (26.0%) out of the 196 invited children participated; there were 31 males and 20 females. The mean age was 13.4 years (standard deviation 1.1 years). Eighty traumatized anterior teeth were involved, with the maxillary centrals being the commonest (68, 85%). Twenty-three (45.1%) participants had more than one traumatized tooth. The commonest dental trauma was enamel fracture, which involved the dentine (39, 48.8%). The main treatments given were composite build-up (36, 45%) and root canal treatment (42, 52.5%). With the CPQ_11-14, in the oral symptoms domain, the number adversely affected before treatment fell from 30 (58.8%) to 3 (5.9%) (P < 0.001); in the emotional well-being domain, the number dropped from 35 (68.6%) to 10 (19.6%) (P < 0.001); and in the social well-being domain, the number fell from 34 (66.7%) to 22 (43.1%) (P = 0.004). However, in the functional limitation domain, the number adversely affected increased from 24 (47.1%) before to 46 (90.2%) after treatment (P < 0.001). Treatment resulted in a significant improvement in the QoL of participants, especially regarding their oral symptoms, and emotional and social well-being. However, there was worsening in the functional limitation domain. There is the need to introduce oral health into the school curriculum in order to encourage early reporting and prompt treatment of traumatic dental injuries.
