The included studies reported few , if any , endodontic complications .
Little or no differences emerged between teeth restored with  composite resins  and those restored with amalgam .
Composite resin is used extensively for restoration of teeth with vital pulps .
Although cell culture studies have disclosed harmful effects on pulpal cells , any untoward clinical effects , manifest as adverse pulpal responses , have yet to be determined .
This study comprises a systematic review , design ed to address the question of whether the risk of endodontic complications is greater with  composite resin restorations  than with  other restorative material s  , such as  amalgam .
Ten-year longitudinal clinical evaluation of a visible light cured posterior composite resin.
Using modified USPHS criteria , we evaluated annually for ten years 91 cases restored with visible light cured posterior composite resin LFP ( Base resin : UDMA ; filler : micro crushed type , alumino-silicate , barium glass and silica , 85 wt% , 74 vol% ) . The 91 cases restored with LFP decreased to 68 in ten years . Of the 23 cases that were lost , one result ed from a pulpal reaction immediately following restoration , four were extracted owing to periodontal disease or extrusion of third molars , two became abutments owing to loss of an adjacent tooth , eight had recurrent caries , and eight were lost owing to caries on a surface having no relationship to the composite resin restoration . Because we observed comparatively little wear , good marginal adaptability , and no discoloration , we concluded that the ten-year clinical success of LFP was on the whole very good , and that this resin has adequate clinical merit as a restorative material for posterior teeth when restricted to restorations covering comparatively small areas
