Atraumatic restorative treatment restorations performed with high-viscous GIC present similar survival/success rates to conventional approach using composite resin or amalgam for occlusoproximal restorations in primary teeth and can be suggested as a good option for occlusoproximal cavities in primary molars .
BACKGROUND Atraumatic restorative treatment ( ART ) has demonstrated good longevity when used for single-surface restorations , but lower success rates are reported for occlusoproximal surfaces .
AIM This systematic review and meta- analysis aim ed to verify the pooled success rate of  occlusoproximal ART restorations in primary teeth considering the outcomes : longevity , pulp damage , or caries lesion progression .
Shear bond strength of six restorative materials.
The purpose of this study was to determine and compare the shear bond strength of a conventional glass-ionomer cement , a resin modified glass-ionomer , a composite resin and three compomer restorative material s. Dentin of the occlusal surfaces from sixty extracted human permanent molars were prepared for shear bond strength testing . The specimens were r and omly divided into six groups of 10 each . Dentinal surfaces were treated according to the instructions of manufacturers for each material . Each restorative material was placed inside nylon cylinders 2 mm high with an internal diameter of 3 mm , which were placed perpendicular to dentin surfaces . Shear bond strengths were determined using an Universal Testing Machine at crosshead speed of 0.5 mm/min in a compression mode . Conventional glass-ionomer , Ketac-Molar aplicap showed the lowest mean shear bond strength 3.77+/-1.76 ( X + /- SD MPa ) and the composite resin , Heliomolar showed the highest mean shear bond strength 16.54+/-1.65 while the mean bond strength of Fuji II LC was 9.55+/-1.06 . The shear bond strengths of compomer restorative material s were 12.83+/-1.42 , 10.64+/-1.42 and 11.19+/-1.19 for Compoglass , Hytac and Dyract respectively . ANOVA revealed statistically significant differences in the mean shear bond strengths of all groups ( P<0.001 ) . No statistically significant difference was found between the three compomer material s ( P>0.5 ) . Ketac-Molar and composite resin showed statistically significant difference ( P<0.0005 ) . The mode of fracture varied between material s. It is concluded that the compomer restorative material s show higher shear bond strength than conventional glass-ionomer and resin modified glass-ionomer , but less than composite resin . The fracture mode is not related to the shear bond strengths values
