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 .
One-year clinical evaluation of composite and ceramic inlays in posterior teeth.
STATEMENT OF PROBLEM There are only a few studies available that deal with the clinical behavior of composite and ceramic inlay systems as potential substitutes for amalgam restorations . PURPOSE This prospect i ve clinical trial evaluated composite and ceramic inlay systems for clinical acceptability as restorative material s in single or multisurface cavities of posterior teeth and provided 1-year results . MATERIAL AND METHODS Forty-seven composite inlays ( Tetric , Blend-a-lux , Pertac ) and 24 heat-pressed ceramic inlays ( IPS Empress )  were placed in 45 patients by 7 student operators under the supervision of an experienced dentist . The first clinical evaluation was performed 11 to 13 months after placement of the restorations and used modified United States Public Health Services criteria . RESULTS Satisfactory results over this period were found , as 100 % of ceramic inlays and 94 % of composite inlays were assessed to be clinical ly excellent and acceptable . Only 3 composite inlay restorations were scored delta ( unacceptable ) . Two inlays exhibited secondary caries and 1 demonstrated loss of pulp vitality . For the criteria " anatomic form of the surface " and " marginal integrity , " ceramic inlays were significantly better than composite inlays . CONCLUSION Posterior tooth-colored inlays provided acceptable and excellent clinical service , even if they are placed by relatively inexperienced student operators
