High-viscosity glass-ionomer cements increased interproximal fluoride concentration more than resin-based fluoride-containing sealants


The latest update of the Cochrane review on fissures sealants (Ahovuo-Saloranta et al 2013) confirmed the use of resin-based sealants as a effective method of preventing or controlling occlusal caries.  The Cochrane review included 15 trials comparing glass ionomer with resin sealants and there was insufficient evidence to make any conclusions about the superiority of [read the full story…]

Bisphenol-A is released after placement of some dental pit and fissure sealants


The release of Bisphenol-A (BPA) from dental resins has attracted attention from researchers, and it has been described as an endocrine disruptor chemical. The aim of this review was to assess the short- and long-term release of BPA in human tissues (saliva, blood serum and urine) after treatment with dental pit and fissure sealants. Searches [read the full story…]

Fissure sealants have been in use since the 1960s and previous reviews have shown them to be effective in reducing caries.  This review is the 4th update of the Cochrane review by Ahovuo-Saloranta et al and includes studies up November 2012.  The main aim of the review was to compare the effects of different types [read the full story…]

Another critical summary from American Dental Association Centre for Evidence-based Dentistry – March 2013


This latest critical summary prepared under the auspices of the ADA Center for Evidence Based Dentistry looks at a 2012 meta-analysis by Kühnisch et al that looks at the retention rates of pit and fissure sealants. The results of the meta-analysis suggest that resin-based sealants have the highest retention rates at 5-years. The appraiser notes [read the full story…]

School- based trial shows benefit of sealants for caries prevention in high-risk population at 1 year


Fissure sealants have been available since the 1960’s  and a 2008 Cochrane review by  Ahovuo-Saloranta et al  highlighted their effectiveness for preventing occlusal caries noting that their effectiveness is obvious in high caries risk children.   The aim of this new study by Muller-Bolla  et al, was to assess their effectiveness in a school-based dental sealant [read the full story…]

Sealants, fluoride varnish and silver diamine fluoride compared


Dental caries is unfortunately still a common problem among children worldwide.  Cochrane reviews have shown the effectiveness of pit and fissure sealants (Hiiri et al  2009)  and fluoride varnishes (Marinho et al 2002) . While other reviews have found silver diamine fluoride (SDF) to be effective (Rosenblatt et al 2009).  The aim of this trial [read the full story…]

This critical appraisal of a update of a systematic review was prepared under the auspices of the American Dental Associations Centre for Evidence-based Dentistry. The aim of the review (Mickenautsch & Yengopal 2011) was to assess the caries-preventive effect of glass ionomer and resin-based fissure sealants on permanent teeth. This 2011 review was itself an [read the full story…]

Rubber dam use for children's dental treatment reduced patient and operator stress


Rubber dam is recommended for isolating the working field during adhesive dentistry procedures. However, dentists often omit rubber dam, particularly in paediatric dentistry, supposing that it would stress the patient. The aim of this study was to evaluate subjective and objective stress parameters in children and adolescents during dental treatment when using rubber dam compared [read the full story…]
