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 .
Predictors of root canal treatment in teeth with full coverage restorations.
This case-control study sought to identify variables predictive of subsequent root canal therapy ( RCT )  in teeth receiving full coverage restorations . The University of North Carolina School of Dentistry 's computerized treatment data base was used to identify all patients receiving a single-unit crown on a nonendodontically treated permanent tooth from January 1 , 1998 through December 31 , 2002 . These patients then were classified either as cases ( those whose crowned teeth received RCT before July 1 , 2004 ) or controls ( those whose crowned teeth did not ) . Computerized data , chart entries , and dental radiographs were examined to determine pre- , intra- , and postoperative factors of interest . In the final multivariable logistic regression model that included 66 cases and 71 controls , younger age ( p = 0.005 ) and greater extent of coronal and root destruction ( p = 0.020 ) remained statistically significant predictors of case status , though many potentially important predictors were unavailable through chart review . Patients could benefit if prospect i ve studies were conducted to identify factors predictive of subsequent endodontic involvement in newly crowned teeth
