Marginal adaptation and performance of bioactive dental restorative materials in deciduous and young permanent teeth

Objective: The aim of this study was to investigate the adaptation of different types of restorations towards deciduous and young permanent teeth. Materials and Methods: Class V cavities were prepared in deciduous and young permanent teeth and filled with different materials (a conventional glass-ionomer, a resin-modified glass-ionomer, a poly-acid-modified composite resin and a conventional composite resin). Specimens were aged in artificial saliva for 1, 6, 12 and 18 months, then examined by SEM. Results: The composite resin and the polyacid-modified composite had better marginal adaptation than the glass-ionomers,though microcracks developed in the enamel of the tooth. The glass-ionomers showed inferior marginal quality and durability, but no microcracking of the enamel. The margins of the resin-modified glass-ionomer were slightly superior to the conventional glass-ionomer. Conditioning improved the adaptation of the composite resin, but the type of tooth made little or no difference to the performance of the restorative material. All materials were associated with the formation of crystals in the gaps between the filling and the tooth; the quantity and shape of these crystals varied with the material. Conclusions: Resin-based materials are generally better at forming sound, durable margins in deciduous and young permanent teeth than cements, but are associated with microcracks in the enamel. All fluoride-releasing materials give rise to crystalline deposits.

Emergency care of children and young people

Children and young people account for a quarter of all patients treated in emergency departments in the UK, with three million children attending emergency departments every year. Emergency Care of Children and Young People prepares practitioners for the challenges of caring for children in emergency departments. Children requiring emergency care have unique and differing needs and may not respond or cooperate during an initial assessment as an adult would.

Absence makes the professional try harder? Meeting the needs of socially excluded young men who become fathers

Research on socially excluded young fathers has been minimally addressed in the literature (SEU 1999, 2004). Indeed, research on young parents which informs health and social care professionals is often presented ‘through the eyes of the mother’ (Reeves 2006). Young parents in general and young fathers in particular are notoriously difficult to gain access to and engage with (Tyrer et al 2005) particularly if they have had previous negative involvement with the statutory services. Moreover, as Daniel and Taylor (1999, 2001, 2003) point out, professionals working in the health and care services often have an intense ‘maternal’ focus and this often excludes fathers from discussion and decisions about their children. The focus of this paper, drawing on two narrative studies of young fathers aged between 15-24 from the US and USA, is to evaluate the features of professional relationships that young fathers describe as finding helpful. Indeed, the findings discuss moving away from a culture of parenting classes, which all the young men interviewed described as finding problematical and in some cases embarrassing, to a culture of support which actively draws on their strengths and helps them become providers for their new families.
