INTRODUCTION AND OBJECTIVE A large number of colonies of Streptococcus mutans (SM) and Lactobacillus (LB) cariogenic bacteria in the saliva show a high risk of dental caries development. Cotinine is a biomarker of exposure to the tobacco smoke. The aim of the study was assessment of the number of Streptococcus mutans and Lactobacillus in the saliva of n...

The aim of this study was to gain more detailed insights into the genetic evolution and variability of Borna disease virus (BDV). Phylogenetic analyses were performed on field viruses originating from naturally infected animals, the BDV vaccine strain 'Dessau', four widely used laboratory strains and the novel BDV subtype No/98. Four regions of the BDV genome were analysed: the complete p40, p1...

THE PURPOSE of the study was to analyse translucency parameter (TP values) of glass-ceramics fabricated by different techniques and investigate the effect of the corrosive medium on TP values. MATERIALS AND METHODS Three specimens of each type of IPS e.max ceramics (Ivoclar Vivadent, Schaan, Liechtenstein) were made in three colours (A2, C2 and B3) by three fabrication techniques (layering - ...

OBJECTIVE To assess possible relationship between caries experience, salivary cariogenic microflora and free sugar consumption in 6 year and 12 year old children in Riga, to evaluate these variables in risk assessment. MATERIALS AND METHODS 79 children aged 6 and 96 children aged 12 were examined clinically and by bitewing X-ray for caries diagnosis. Also all children or their parents were qu...

This in vitro study aimed to evaluate the fracture resistance and mode of failure endocrowns with proximal extension design compared conventional design, assess agreement evaluators on mode. Twenty mandibular third molars free caries approximately similar root lengths crown dimensions were sectioned parallel occlusal plane 2 mm above cementoenamel junction (CEJ). Then, pulp chambers canals acce...
