Effects of continuous irrigation at room temperature or +4ºC on the cyclic fatigue resistance of K3XF instruments.

The present study aimed to evaluate the impact of continuous irrigation with saline solution at room temperature or +4°C on the cyclic fatigue resistance of K3XF files. Forty-eight new K3XF files (#30, .04 taper) were randomly assigned to three groups: control group (no irrigation), continuous irrigation with saline solution at room temperature, and continuous irrigation with saline solution at +4°C.

Association between Rheumatoid Arthritis and Apical Periodontitis: A Cross-sectional Study.

Objective: The present cross-sectional study aimed to investigate possible association between Rheumatoid Arthritis (RA) and Apical Periodontitis (AP).

Methods: In table one it is mentioned 48 patients diagnosed with RA were included in the experimental group. Another 48 healthy age- and gender-matched participants who reported no history of any systemic disease were selected to form the control group.

Effect of calcium hydroxide mixed with lidocaine hydrochloride on postoperative pain in teeth with irreversible pulpitis and symptomatic apical periodontitis: a preliminary randomized controlled prospective clinical trial.

Objectives: To investigate the effect of calcium hydroxide mixed with lidocaine HCl on postoperative spontaneous pain.

Materials And Methods: Sixty patients having irreversible pulpitis and symptomatic apical periodontitis with a preoperative spontaneous pain and percussion pain which was more than 50 on a visual analogue scale (100 mm VAS) were included in this study. After the preparation of the root canals, the patients were randomly distributed into two groups according to the calcium hydroxide vehicle, control group (mixed with saline) and calcium hydroxide mixed with lidocaine HCl (n = 30).

Association of ankylosing spondylitis with radiographically and clinically diagnosed apical periodontitis: A cross-sectional study.

Background: There are no studies evaluating the possible association between ankylosing spondylitis (AS) and apical periodontitis (AP).

Objectives: The aim of the present cross-sectional study was to investigate the possible association between AS and AP.

Material And Methods: Fifty patients diagnosed with AS, receiving treatment at the Rheumatology Clinic in Erzurum, Turkey, were included in the experimental group.

Success of maintaining apical patency in teeth with periapical lesion: a randomized clinical study.

Objective: The aim of this study was to evaluate the effect of maintaining apical patency on periapical healing and postoperative pain levels in teeth with necrotic pulp and apical periodontitis.

Method And Materials: Fifty mature teeth with periapical lesions were randomly distributed into two treatment groups: patency, and nonpatency (n = 25). Patients were followed up over a 12-month period using clinical and radiographic assessments.
