Aims: To assess self-perceived oral health-related quality of life (OHRQoL) in 12-year-olds living in two areas in the Barents region: North-West Russia (Arkhangelsk) and Northern Norway (Tromsø). Methods: Sampling was performed according to a stratified cluster design and consisted of 590 Russian and 264 Norwegian 12-year-olds and their parents. After written consent from their parents, 514 Russian ...

Hevelser og smerter i kjeven er ofte assosiert med infeksiøs odontogen sykdom og vil typisk diagnostiseres og behandles hos tannlege. I noen tilfeller kan imidlertid ikke tanninfeksjoner påvises. Vi presenterer fire sykehistorier hos barn som illustrerer ulike utfordringer ved en velkjent, men relativt dårlig definert diagnose i medisinen.

The aim was to assess perceived stress (PS) and factors associated with PS in Russian medical and dental students. A total of 406 medical and 283 dental students aged 18–25 years that attended the Northern State Medical University in Arkhangelsk, North-West Russia participated in this cross-sectional study. A structured, self-administered questionnaire was used to collect information on socio-demographic ...

An antimicrobial technique based on photo-oxidation of caffeic acid (CA) has recently been developed, but its effect on biofilm-forming bacteria is unknown. The present study aimed to evaluate the effect of photo-irradiated CA against Streptococcus mutans (cariogenic bacteria) biofilm as it relates to hydroxyl radical formation. S. mutans biofilms grown on hydroxyapatite disks were immersed in CA ...

Background: Pit and fissure sealants (sealants) are widely used as a non-operative preventive method in public dental health in Finland. Most children under 19 years of age attend the community-organized dental health services free of charge. The aims of this study were to find out to what extent sealants were applied, what the attitudes of dental professionals towards sealant application were, ...

Objective: The aims of this study were to assess the prevalence of temporomandibular disorders (TMD) amongst adolescents and to contrast the prevalence of TMD according to the DC/TMD clinical examination protocol versus the prevalence of TMD pain according to two screening questions. <br>Material and methods: Two hundred and ten adolescents living in the county of Bergen, Norway, were offered an ...

<i>Objective</i>: To describe the prevalence of dental anxiety (DA) among adolescents in Tromsø and Balsfjord region in northern Norway and present a multivariate logistic regression model to predict high dental anxiety scores (DASs) among these adolescents.<p> <p><i>Materials and methods</i>: We used self-report questionnaires and clinical dental examination data from adolescents registered in ...

<i>Background</i>: The Tn<i>916</i>-Tn<i>1545</i> family of Integrative Conjugative Elements (ICE) are mobile genetic elements (MGEs) that play a role in the spread of antibiotic resistance genes. The Tn<i>916</i> harbors the tetracycline resistance gene <i>tet</i>(M) and it has been reported in various bacterial species. The increase in the levels of tetracycline resistance among oral streptococci ...

Prisoners’ oral health and general health are closely connected and generally poorer than that of the wider population. Moreover, knowledge of prisoners’ health literacy is scarce. This study aimed to explore prisoners’ perceived oral and general health and how they accessed, understood and assessed health information to gain insight into their health literacy. Twelve prisoners in a high-security ...

Integrons are genetic elements consisting of a functional platform for recombination and expression of gene cassettes (GCs). GCs usually carry promoter-less open reading frames (ORFs), encoding proteins with various functions including antibiotic resistance. The transcription of GCs relies mainly on a cassette promoter (P_C), located upstream of an array of GCs. Some integron GCs, called ...
