Post-operative pain in non-surgical root canal treatment after sealer-based obturation versus warm vertical compaction: A randomized clinical trial.

Aim: Post-operative pain may occur after non-surgical root canal treatment (NSRCT). The root filling technique and choice of sealer may be contributing factors. This randomized controlled clinical trial compared post-operative pain and analgesics intake after NSRCT using a sealer-based obturation technique (SBO) with single-cone gutta-percha and calcium silicate sealer (CSS) versus a warm-vertical compaction (WVC) technique with gutta-percha and a resin-based sealer (RBS).

Effect of selected accelerants on setting time and biocompatibility of mineral trioxide aggregate (MTA).

Objective: Various additives have been suggested to be used with mineral trioxide aggregate (MTA) to improve its handling characteristics. The purpose of this study was to evaluate the effects of various additives on setting time and cell attachment on gray MTA (GMTA).

Study Design: Single-rooted caries-free teeth were split, and dentin disks with class I cavity were made and filled with test and control materials.

Porphyromonas gingivalis lipids inhibit osteoblastic differentiation and function.

Porphyromonas gingivalis produces unusual sphingolipids that are known to promote inflammatory reactions in gingival fibroblasts and Toll-like receptor 2 (TLR2)-dependent secretion of interleukin-6 from dendritic cells. The aim of the present study was to examine whether P. gingivalis lipids inhibit osteoblastic function.

Cytotoxicity evaluation of endosequence root repair material.

Objective: The purpose of this study was to evaluate the cytotoxicity of EndoSequence Root Repair Material (Brasseler USA, Savannah, GA) and compare it with gray and white MTA.

Study Design: Samples of 2 mg freshly mixed or set gray MTA (GMTA), white MTA (WMTA), EndoSequence Root Repair Material (ERRM), and AH26 were eluted with 300, 600, and 1,000 microL cell culture medium for 24 and 72 hours. L929 cells were seeded into 96-well plates at 3 x 10(4) cells/well and incubated with 100 microL elute from each elute group.
