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 .
Coronal and apical lesions, environmental factors: study in a modern and an archeological population
Apical periodontitis ( AP ) are frequent findings in contemporary dental practice in association with dental pathology or dental care . They have also been studied from an anthropological background . The purpose of this study was to compare the prevalence of apical and dental lesions in an archeological Middle Ages sample and a modern population , and to evaluate the influence of environmental factors . Both the archaeological sample group and dental practice subjects were from southern France . The study included full mouth surveys of 252 individuals ( 2,780 teeth ) from a historic necropolis and 223 subjects ( 5,678 teeth ) r and omly selected from the Gard area .  Tooth wear , caries , and AP were accounted for clinical ly and radiographically according to specific indexes . Significant differences were found between period and age in the archeological sample as regards the main risk factors for AP . Antemortem teeth loss and dental wear had been reduced , whereas caries rates and AP had increased between archaeological and modern population . The AP ratio was associated with the level of dental care in the modern population . Although significant variations could be observed between archaeological periods , the rupture in E3 ( sixteenth and seventeenth centuries ) leads to consider the associated population as a premodern . However , it was found that although cultural and alimentary factors seemed to be the main risk factors in an archeological population , dental care seemed to have a strong influence on AP ratio in modern ones
