Effect of newer all-in-one irrigants on root dentin wettability and surface roughness - An in vitro study

All-in-one irrigants introduced recently claim to impart added benefits for endodontic disinfection; however, their effects on root dentin need to be evaluated.

The aim of the study was to evaluate the dentinal wettability and surface roughness of Triton and Twin Kleen irrigating solutions on root dentin.

Eighty dentin blocks (6 mm × 6 mm) were prepared using middle root portion obtained by horizontal sectioning of forty single-rooted extracted human mandibular premolar teeth which were further mounted in acrylic blocks (4 cm × 4 cm) and were randomly allotted into four groups (n = 20) and subjected to 10 ml of experimental irrigating solutions for 5 min as follows, group 1: normal saline (Control), group 2: 5.25% sodium hypochlorite (NaOCl) +17% ethylenediaminetetraacetic acid (EDTA), group 3: Triton, and group 4: Twin Kleen. Half of the specimens in each group (n = 10) were tested for wettability by using goniometer, and another half (n = 10) were subjected to surface roughness using atomic force microscopy.

One-way analysis of variance and post hoc Tukey test (P ≤ 0.05).

Group 3 exhibited the highest wettability followed by group 4, group 2 and least in group 1 (control group). Surface roughness was found to be highest in group 2 followed by group 3, group 4 and least in group 1.

Triton and Twin Kleen have shown better wettability and less surface roughness compared to 17% EDTA and 5.25% NaOCl.
