How does a Truss conservative endodontic access cavity impact the degree of intra-canal disinfection and postoperative pain?

Endodontic access cavity design impacts reduction in bacterial load following chemo-mechanical preparation. The TEC allowed for greater reduction in bacterial levels compared to the TREC. This is likely due to reduced access restricting effective debridement. There are benefits to retaining more dentine with regards to improved fracture resistance following treatment, so further research is required in this area. Additionally, neither the TEC nor TREC had any impact on postoperative pain levels.
