Has children's oral health-related quality of life improved more following necrotic primary molars pulpectomy or extraction?

Study Design: A randomised parallel controlled clinical trial was conducted between 2013 and 2015 at the University of Sao Paulo, Brazil, to assess the impact of pulpectomy or extraction on the oral health-related quality of life (OHRQoL) of children with pulp necrosis in primary molars.

Study Selection: Children between the ages of 3 and 5 who were in good health but had extensive caries in at least one primary molar with signs of pulpal necrosis (also as seen radiographically, caries reaching the pulp with no signs of internal or external resorption) were considered for inclusion. Additionally, teeth with sufficient structure for rubber dam placement were also included.

Environmental impact of the supervised toothbrushing programme amongst children in Scotland.

Objectives: To understand the environmental impact of providing a nationwide supervised toothbrushing programme (Childsmile) for 5-year-old children in Scotland.

Methods: A life cycle assessment was conducted to assess the annual environmental effects of the supervised toothbrushing programme in early years childcare, as well as each dental procedure (dental restoration under local anaesthesia (LA), single tooth extraction under LA, and multiple teeth extraction under general anaesthesia) spanning from 2001/02 to 2009/10. The expected savings in annual carbon dioxide equivalent (CO2e) emissions for all combined dental treatments in subsequent years were calculated compared to those in 2001/02.
