Presentation and subsequent care of dental injuries sustained by New Zealand adults.

Background/aims: Injuries to permanent teeth are common and can have lasting effects, but knowledge of their consequences is deficient because there is a lack of information from longitudinal follow-up studies of adult populations. The aim of this study was to use routinely collected adult dental trauma data from New Zealand's no-fault, Government-run social insurance scheme-the Accident Compensation Corporation-to investigate the presentation and subsequent care of dental injuries sustained by adults.

Methods: Cross-sectional analysis of all new dental injuries recorded during 2008 was followed by prospective analysis of all treatment claimed in the following five years for all new injuries recorded in June 2008 for adults aged 18+ years.

Alkaline Tolerance and Biofilm Formation of Root Canal Isolates of Enterococcus faecalis: An In Vitro Study.

Introduction: The aim of this study was to compare the effects of glucose and glycerol (provided as principal fermentable supplements) on alkaline tolerance and biofilm-forming capabilities of root canal-derived strains of Enterococcus faecalis and those from other environments.

Methods: The planktonic growth kinetics and the biofilm-forming capabilities of E. faecalis isolates (identified by 16S ribosomal DNA sequencing) were compared when supplied with glucose and glycerol at pH levels of 8 and 11 in a microtiter plate.

Traumatic dental injuries among New Zealanders: Findings from a national oral health survey.

Background/aim: Little is known about adult dental trauma experience at the population level. The aim of this study was to estimate the prevalence and associations of dental injuries in New Zealand (NZ) adults.

Materials And Method: Information about dental and orofacial trauma in a representative sample of NZ adults (aged 18-94) was collected in a national oral health survey.

Qualitative comparison of sonic or laser energisation of 4% sodium hypochlorite on an Enterococcus faecalis biofilm grown in vitro.

The effectiveness of sonic activation, laser activation and syringe irrigation of 4% sodium hypochlorite in removing an Enterococcus faecalis biofilm was compared. Biofilms were grown in extracted human single rooted teeth using a flow cell apparatus. After 4 weeks' growth, teeth were subjected to each treatment using 4% sodium hypochlorite and radicular dentinal surfaces of the root canals were analysed by scanning electron microscopy.
