Comparison of Dental Caries and Oral Hygiene Status of Children in Suburban with those in Rural Population of Southwestern Nigeria

Objective: To compare prevalence of dental caries, oral hygiene status and associated risk factors of children in suburban and rural communities in the Southwest region of Nigeria. Material and Methods: Secondary data was extracted from cross-sectional researches conducted in two study locations involving 8 to 12 year olds.  Data retrieved included age, gender, family structure, socioeconomic status, oral hygiene and dental caries. Caries assessment was done using WHO Oral Health Survey methods. Oral hygiene data was collected using Simplified Oral Hygiene Index (OHI-S) by Greene and Vermillion. Statistical significance was established at p<0.05. Results: The prevalence of dental caries in Group A and Group B study participants were 13.4% and 22.2% respectively. Children from rural community had significant higher caries prevalence (p=0.00) and poorer oral hygiene (P=0.00) compare with their counterparts in the suburban community. There was a significant association between oral hygiene, age and dental caries in suburban participants (p=0.02) while among the rural participants there was significant association between gender and dental caries (p=0.04). Children with poor oral hygiene have increased odds of having dental caries compared to children with good oral hygiene in the two study communities. Conclusion: Dental caries was more prevalent among the rural dwellers than the sub-urban dwellers. There is a need to make oral health care services/products available, accessible and affordable for the rural community

Use of the Hall technique by specialist paediatric dentists: a global perspective.

Background The Hall technique (HT) is popular with UK paediatric dentists (PDs). Global PDs perception/use of HT is unknown.Aim To investigate global PDs opinions/use of HT.Materials and methods A cross-sectional questionnaire of 26 questions was sent to specialist PDs across the globe.Results Responses of 709 PDs from six continents were obtained. The majority (n = 654, 92.32%) had heard about HT but only 50.6% (n = 358) used it, with wide country variations. Respectively, 37.5%, 31.5% and 31% were neutral, against or supportive of HT when they initially heard about it. Only 17% of HT users said it was always the treatment of choice for non-pulpal asymptomatic carious primary molars (NPACPMs), 62% would take a pre-operative radiograph, 65% would consider using high speed drills before HT, 63% would never consider HT under general anaesthesia, 56% would use HT under N2O sedation. Finally, in a clinical scenario of a NPACPM in a cooperative 6-year-old, 75% of PDs would choose conventional restorative methods over the HT.Conclusion The HT is recognised, but not used, by an outright majority of PDs across the globe. Identifiable barriers such as lack of training, perception as substandard dentistry and perceived lack of evidence reduced its use

Undergraduate dental students' perception, educational satisfaction, and attitude regarding the use of rubber dam

Background and Objective: The rubber dam is used in dentistry to create saliva-free working environment during operative procedures. Despite its numerous advantages, utilization is poor in dental schools. We sought to determine undergraduate dental students' perception, educational satisfaction, and attitude regarding the use of rubber dam. Materials and Methods: This cross-sectional survey was carried out among 5th and 6th year undergraduate dental students. A structured questionnaire was developed that sought their perception, educational satisfaction, and attitude regarding the use of rubber dam. Data collected were analyzed using IBM SPSS version 21.0. P <0.05 was considered statistically significant. Results: One hundred and nine students participated in the study; 66 (60.6%) females and 43 (39.4%) males with a mean age of 23.4 ± 2.02. Most of the students, i.e., 73 (67%) were satisfied with their classroom experience with regard to the use of rubber dam but were least satisfied with their laboratory and clinical training. There was a statistically significant association between the students' satisfaction with their training in the use of rubber dam and the confidence to use the rubber dam on their patients (P = 0.001). Conclusion: The students agreed to the importance of rubber dam but were not satisfied with their hands-on clinical training. The use of rubber dam postgraduation may be influenced by the dental educator's method of training, motivation, and consistency in its use. Students who acquire competence and are confident in the use of rubber dam during their undergraduate training are more likely to continue to use the skills following graduation

Factors Associated with Changes in E-Cigarette Use and Tobacco Smoking by Adolescents and Young People in Nigeria during the COVID-19 Pandemic

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&rsquo; 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 &lt; 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
