Evaluation of the effectiveness of a mobile application in the management of dental anxiety: A randomised controlled trial.

Background: The software, which was developed according to the principle of perceived control, can be installed on tablets and smartphones and used by patients to help them control their anxiety.

Objective: The aim of this study was to evaluate the effectiveness of a specially designed mobile application developed to provide patients with a sense of anxiety control during the various stages of endodontic treatment. The patients' anxiety was assessed by measuring their salivary cortisol levels.

Microhardness evaluation of root dentin after using resin sealer solvents.

This study aimed to assess the effects of methyl ethyl ketone (MEK) and ethyl acetate (EA) on dentin microhardness, used as resin sealer solvents. Eighty halves of single-rooted teeth were randomly divided into four groups to apply MEK, EA, chloroform, or saline solution. Vickers hardness values were measured for three root levels before and after the direct application of solvents for 5 and 15 minutes or a 1-minute application with ultrasonic agitation.

Evaluation of postoperative pain/discomfort after intracanal use of Nd:YAG and diode lasers in patients with symptomatic irreversible pulpitis and asymptomatic necrotic pulps: a randomized control trial.

Objectives: This study aimed to investigate the ability of the diode and Nd:YAG lasers to decrease postoperative pain/discomfort after intracanal application in vital and devital endodontic cases.

Material And Methods: One hundred two patients with symptomatic irreversible pulpitis and asymptomatic necrotic pulps were selected and randomly divided into three groups. After chemomechanical preparation, Nd:YAG and diode laser was applied to first and second groups for final treatment of the root canals.

Virgin Olive Oil, Soybean Oil, and Hank's Balanced Salt Solution Used as Storage Media on Periodontal Ligament Cell Viability.

The purpose of this study was to compare the effects of virgin olive oil (VOO), soybean oil (SO), and Hank's Balanced Salt Solution (HBSS) on the vitality of periodontal ligament (PDL) cells of simulated avulsed teeth. Forty freshly extracted teeth were randomly divided into three experimental groups (n equals 10), one positive control group (n equals five), and one negative control group ( equals five). The experimental teeth were air-dried for 30 minutes and then soaked in one of the three storage solutions: HBSS, VOO, or SO.

The effectiveness of various irrigation protocols on organic tissue removal from simulated internal resorption defects.

Aim: To evaluate the effectiveness of NaOCl, NaOCl-EDTA and NaOCl + HEBP activated by ultrasonics and XP-endo Finisher on organic tissue removal from simulated internal root resorption cavities.

Methodology: The root canals of 144 single-rooted teeth were instrumented. The teeth were split longitudinally, and semicircular cavities were prepared in the canal walls on each half of the roots.
