Prevalence and factors associated with traumatic dental injuries among schoolchildren in war‐torn Libya

Background/Aims No previous epidemiological study has investigated the prevalence and associated factors of traumatic dental injuries (TDIs) among Libyan children. Such information is required for the planning and evaluation of health services. The aim of this study was to assess the prevalence of TDIs and associated factors among 12‐year‐old schoolchildren in Benghazi, Libya. Methods Data for this study were collected as part of a comprehensive, cross‐sectional survey investigating oral health status and treatment needs of 12‐year‐old schoolchildren in Benghazi, Libya, between December 2016 and May 2017. Sociodemographic information was collected through a dental health questionnaire. The children were assessed for oral health status, including TDIs according to modified World Health Organization (WHO) classification criteria, in their classroom by trained and calibrated examiners. Anthropometric measures, lip competence and overjet were all assessed and reported. History of TDIs was sought among those affected. Logistic regression models were applied for TDIs as an outcome variable. The statistical significance for all tests was ≤0.05. Results Data from 1134 participants were included in this study. TDIs were observed in 10.3% of the sample. Most of these TDIs were enamel fractures only (55.6%) and enamel and dentine fractures (35.9%). “Falling” was the most common cause of TDIs, accounting for 51% of cases. While increased overjet appeared to be associated with higher risk of TDIs (OR: 1.92; 95% CI: 1.29‐2.86), being female (OR: 0.34; 95% CI: 0.22‐0.53) and overweight (OR: 0.33; 95% CI: 0.13‐0.83) were also associated with lower risk of having TDIs. Conclusions This survey showed that a considerable proportion (10.3%) of 12‐year‐old Libyan children had TDIs, with relatively high unmet treatment needs. More efforts are required to develop effective prevention programmes and to enhance the provision of dental treatment of TDIs for Libyan children

Prevalence of dental caries in 5-year-old Greek children and the use of dental services: Evaluation of socioeconomic, behavioural factors and living conditions

Objectives To assess dental caries and use of dental services experience in 5-year-old children attending public kindergartens in Attica, Greece and to examine the influence of certain socioeconomic factors and living conditions as well as dental behaviours and attitudes. Methods In this cross-sectional study, a random and stratified sample of 605 Greek children was examined using decayed, missing, filled tooth surfaces and simplified debris indices. The use of dental services was measured by children's dental visits (any dental visit up to the age of 5 years). Care Index was also calculated. Risk indicators were assessed by a questionnaire. Zero-inflated Poisson and Logistic Regression Analysis were generated to test statistical significant associations. Results The prevalence of dental caries was 16.5%. Care Index was 32% and dental visits were reported for the 84% of the children. Medium Socio-Economic Level (SEL) was associated with no detectable caries. High SEL was related to decreased decayed, missing, filled teeth values, while female gender and rented houses had the opposite effect. The age of the mother (35-39 years) and the higher SEL were related to higher levels of dental services use. Conclusions It is suggested that there are differences in the experience of dental caries and use of dental services among preschool children in Attica, which are related to demographic, socioeconomic factors and living conditions. Dental public polices should focus on groups with specific characteristics in order to improve oral health levels of disease-susceptible populations. © 2013 FDI World Dental Federation

Socio-demographic and area-related factors associated with the prevalence of caries among preschool children in Greece

Objective: To assess dental caries experience in 4-6 year old children of the Athens Metropolitan Area attending public kindergartens and investigate the association of area deprivation and immigration status on dmft. Basic research design: A cross-sectional study of a large area-stratified sample of 683 kindergarten children was conducted during the academic years 2009-2011. Dental caries experience and oral hygiene level were assessed using dmft and the Simplified Debris index (DI-s). Area deprivation was defined using a pre-established Geo-demographic System for Attica. Zero-inflated Poisson regression models were used to test associations between the dmft index and related factors; gender, age, immigrant background and area deprivation. Differences were reported in terms of predicted probabilities. Results: Caries prevalence was 20.8% (95% CI17.8,24.0%). The mean dmft and DI-s scores were 0.67 (95% CI0.61,0.74) and 0.16 (95% CI0.14,0.18) respectively. The mean predicted probability of having no detectable caries experience was 79% (95% CI75, 83%), while the probability of having dmft=1 or 2 was 6% (95% CI5,8%) and 2% (95% CI1,3%) respectively. The predicted probability of having no caries experience was substantially lower for males, those from the least affluent areas and non-Greeks by 5%, 18% and 31% respectively. Regarding dmft scores, deprived children were more likely to have 1 or 2 teeth with caries experience by 9% (95% CI4,13%) and 6% (95% CI2,10%) respectively, while the corresponding differences for non-Greeks were 10% (95% CI7,14%) and 12% (95% CI7,15%). Conclusions: Socio-demographic and area-related variations in oral health exist among kindergarten children in Athens. © BASCD 2017

Dental erosion prevalence and associated risk indicators among preschool children in Athens, Greece

Objectives: The aims of the study were to investigate dental erosion prevalence, distribution and severity in Greek preschool children attending public kindergartens in the prefecture of Attica, Greece and to determine the effect of dental caries, oral hygiene level, socio-economic factors, dental behavior, erosion related medication and chronic illness. Material and methods: A random and stratified sample of 605 Greek preschool children was clinically examined for dental erosion using the Basic Erosive Wear Examination Index (ΒΕWE). Dental caries (dmfs) and Simplified Debris Index were also recorded. The data concerning possible risk indicators were derived by a questionnaire. Zero-inflated Poisson regression was generated to test the predictive effects of the independent variables on dental erosion. Results: The prevalence of dental erosion was 78. 8 %, and the mean and SE of BEWE index was 3. 64 ± 0. 15. High monthly family income was positively related to ΒΕWE cumulative scores [RR = 1. 204 (1. 016-1. 427)], while high maternal education level [RR = 0. 872 (0. 771-0. 986)] and poor oral hygiene level [DI-s, RR = 0. 584 (0. 450-0. 756)] showed a negative association. Conclusions: Dental erosion is a common oral disease in Greek preschool children in Attica, related to oral hygiene and socio-economic factors. Clinical relevance: Programs aimed at erosion prevention should begin at an early age for all children. © 2012 Springer-Verlag
