05). The mean time taken reaching the working length for continuous rotation was less as compared to TF adaptive motion; however, the difference was nonsignificant (

> 0.05).

We recorded higher instrument separation and deformation with the TF method and adaptive gesture. The TF system showed additional time to achieve the working distance as compared to the Endostar E3 system.

The TF system showed higher instrument separation and deformation, and it requires additional time to achieve the working distance compared to the Endostar E3 system. Hence, the Endostar E3 system is effective in achieving required clinical results.

To analyze the impact of two nanocoating materials, EQUIA Forte nanocoat and universal adhesive, on flexural strength, color changes, surface roughness, and microleakage of bulk-fill and resin-modified glass ionomer cements (RM-GICs).

A total of 45 specimens were prepared for each group, bulk-fill (EQUIA Forte Fil) and RM-GI (Fuji II LC) cements, according to manufacturer's instructions for flexural strength, color change, and surface roughness tests. Each group was equally subdivided into three subgroups according to coating materials used; either without a coat (negative control) or covered with EQUIA Forte coat or universal adhesive. For the flexural strength test, 15 bar-shaped specimens were prepared using a rectangular-split Teflon mold (25 × 2 × 2 mm), then the test was conducted using a universal testing machine. Thirty disk-shaped specimens were prepared for color change and surface roughness tests using cylindrical-split Teflon mold (10 mm diameter and 2 mm height). The color change was measuredd in the coated subgroups with no significant difference between the coating materials.

Nanocoats, especially the EQUIA Forte nanocoat, positively impact the physicomechanical properties and adaptation of bulk-fill GICs and RM-GICs.

The application of nanocoats on GI restorations is highly recommended.

The aim of this

randomized study is to evaluate the efficiency of gutta-percha cones that match a nickel-titanium instrumentation system and nonmatching greater taper cones, when used with continuous warm vertical condensation technique.

Thirty-six straight canals were prepared using ProTaper Next files, and the apical third was obturated using either ProTaperNext cones (group A), ISO uniform greater taper cones (group B), or nonstandardized cones (group C). Cone adaptation time was quantified by the number of required modifications. Micro-computed tomography was used to measure voids and sealer percentage.

There was no significant difference between the groups regarding void volume (

= 0.666), percentage (

= 0.379), and the number of modifications (

= 0.757). Sealer percentage, however, was significantly lower in group B when compared to group A (

= 0.0194).

In straight canals, matching gutta-percha cones were not associated with significantly better obturation or saving time to fit the cone.

Using gutta-percha cones that do not match a nickel-titanium instrumentation system to obturate the straight canals with continuous warm vertical condensation technique is as efficient as using matching cones in terms of obturation quality and ease of cone fit.

To investigate risk factors associated with halitosis in children using OralChroma™.

Sixty-seven children between the ages of 3 and 8 who attended a pre-general anesthesia assessment at the Dental University Hospital at King Saud University, Riyadh, Saudi Arabia, were enrolled in this study after satisfying the inclusion criteria. Demographic data, medical history, and oral hygiene practices were obtained by a standardized questionnaire completed by the parents of each child. Clinical dental examination was conducted to record the following caries index (dmft/DMFT), simplified debris index (DI-S), modified gingival index (MGI), and Winkel tongue coating index (WTCI). selleck chemical Clinical halitosis was assessed using the OralChroma™ device that measures the concentration of volatile sulfur compounds (VSCs) including hydrogen sulfide (H

S), methyl mercaptan (CH

SH), and dimethyl sulfide (CH

SCH

). Statistics were completed using Spearman's correlation coefficient and Mann-Whitney U-test to assess the association with the VSC scores with continuous and binary variables, respectively. Then, multivariate linear regression analysis was performed to detect the degree of association.

High VSC measures were detected in 58 children (87%). The dmft/DMFT was significantly associated with H

S level (β = 26.84, p = 0.034) and CH

SH level (β = 19.96, p = 0.016) after controlling possible confounders. There was no significant association of DI-S, MGI, and WTCI with the VSC measures.

The result suggested that dmft/DMFT score (children's caries experience) is associated significantly with high levels of H2S and CH

SH in the sample studied.

Caries experience in children is a significant risk factor for halitosis and should be considered during the management of halitosis.

This study aimed to assess the occurrence of postoperative pain and associated factors in patients treated endodontically at a Postgraduate Center in Endodontics in Southern Brazil.

The evaluation was performed using the medical records of 658 patients. Pulp conditions, postoperative pain, pain intensity, edema, number of sessions (single or multiple), and medication administration in the postoperative period were analyzed. For data analysis, descriptive analyses and univariate and multiple regressions were performed. In the multiple analyses, odds ratios (OR) and their respective 95% confidence intervals were estimated, crude and adjusted for exposure variables in a binary logistic regression model (p-value < 0.05).

To perform the adjusted logistic regression, all variables associated with

-value <0.10 gender, edema, and pulp condition (bio- and necropulpectomy) entered the crude model. After the multivariate analysis, a statistically significant association was found between the outcome variable of the presence of postoperative pain and the independent variable of pulp condition, and the presence of pain was associated with patients who underwent endodontics on teeth with live pulp and edema with greater chances of postoperative pain.
