Endodontic Treatments and Extractions Following Composite and Amalgam Restoration
Objectives: This study aims to evaluate endodontic treatments and extractions in teeth resorted with composite compared to teeth restored with amalgam within 5 years of restauration placement using secondary data from the BigMouth Repository; a centralized oral health data repository derived from electronic health records at 9 dental schools in the U.S. We hypothesize that composite resin material might compromise the tooth vitality by inducing negative effects to the human dental pulps.
Methods: Data were collected from 1,278 first and second permanent molars that were restored with either composite or amalgam. We only included teeth filled with amalgam or composite that ended up with root canal treatment or extraction within 5 years following the restoration placement date. Chi square test was used to describe our variables, and logistic regression model was performed to assess the relationship between the type of restoration and endodontic treatment or extraction over the 5 years.
Results: We demonstrated that endodontic treatments were higher in teeth restored with composite (n=795, 62.2%) compared to teeth restored with amalgam (n=483, 37.8%) within the 5 years of follow up.
Within the period of 5 years, 60.6% of the composite restored teeth ended up with root canal treatment and 39.4% ended up with extraction. Whereas 55% of amalgam restored teeth ended up with root canal treatment and 44.9% ended up with extraction.
Logistic regression analysis revealed that teeth restored with composite restorations were two times more likely to result with root canal treatment or extraction within the first year of restoration placement compared to teeth restored with amalgam (OR= 1.9; P=0.002), adjusting for age and sex.
Conclusions: The results of this secondary analysis suggest that composite resin restorations in molar teeth have higher odds of ending up with endodontic treatments or extractions when compared to amalgam restorations within the first year of restoration placement.
