RESULTS:There were no...

Objectives The aim of this study is to evaluate the effect using gel and solution forms NaOCI during chemomechanical preparation root canals on postoperative pain at different time intervals. Methodology 114 patients with mandibular molar teeth symptomatic irreversible pulpitis were included in study. All divided into two groups based irrigant used canal (n=57): Group 1, 5.25% NaOCI, 2, gel. filled gutta-percha AH Plus sealer single-cone technique. VAS scale (1-10) was for assessment. After...

Background. This study aimed to examine the retreatment efficiency of four NiTi rotary file systems with micro-computed tomography (micro-CT). Methods. Forty premolar teeth were shaped up F2 using ProTaper Universal system and obturated MTA Fillapex. The root canals scanned micro-CT evaluate volume canal filling before retreatment. samples randomly divided into groups according used remove material (n=10): Retreatment, NEXT, EdgeFile XR, EdgeFile® X3 system. All a device for second time...

To investigate the influence of sonic agitation or laser-activated irrigation techniques on removal chlorhexidine (CHX) and modified triple antibiotic paste (mTAP) sealer penetration depth dislocation resistance Guttaflow Bioseal.Single-rooted mandibular premolars (n=96) were prepared with rotary nickel titanium instruments randomly divided into two groups (n=48) based intracanal medicaments used: Group 1, mTAP; 2, CHX gel. After 7 days, specimens in each group three subgroups (n=16)...

The honey which is produced in the Blacksea Region of Turkey,also known as 'mad honey', includes a toxin was named Andromedotoxin.The causes not only gastrointestinal but also cardiovascular side effects.This (Andrometoxin) derived from R.Luteum and R. Panticum are two members Rhododendron plant family.In this study, we aimed to present patient with typical poisoning findings after consuming mad honey.

The aim of this study was to compare the formation dentinal crack after root canal preparation performed with different heat treated single-file systems.Forty mandibular premolar teeth were randomly divided into four groups according file system be used during (n = 10): Group 1: Reciproc Blue; group 2: One Curve; 3: HyFlex EDM; 4: (control group) hand files. During cleaning and shaping, irrigation a total 10 ml 5.25% sodium hypochlorite 2 mL distilled water. Then sections taken from roots...

Panoramic and periapical radiographs are the most commonly used imaging modalities for diagnosis treatment planning in endodontics.However, these have some limitations as they provide two-dimensional images (1).These include an overlap of anatomical structures geometric distortions such distortion magnification region interest.Cone-beam computed tomography (CBCT) can overcome by providing three-dimensional teeth surrounding tissues (2).CBCT is system that allows digital visualization maxilla...

The aim of this study was to evaluate the root morphology and canal configuration lower upper premolars using cone-beam computed tomography (CBCT), according gender right -left position tooth in Turkish subpopulation.For evaluation anatomy mandibular maxillary premolar teeth, 494 patients were used.In total, 3,880 teeth evaluated.CBCT images examined coronal, sagittal, axial planes.Number roots, canals, configurations determined Vertucci's classification.Qualitative data analysed with...

Objective: Aim of this study is to evaluate the cardiac electrophysiological effects energy drink (Red Bull) on QT and P duration dispersion surface electrocardiogram. Methods: Twenty healthy volunteers older than 17 years age were included study. Subjects with a rhythm except sinus rhythm, history atrial or ventricular arrhythmia, family premature sudden death, palpitations, T-wave abnormalities, QTc interval greater 440 milliseconds, those P-waves intervals unavailable in at least eight...

Cases with periapical lesions or extraoral sinus tracts have both aesthetic and functional problems. Non-surgical endodontic therapies to resolve these problems provide less traumatic solutions wıth higher cost-effectivity. A 14-year-old male patient was admitted our clinic complaints of swelling skin lesion on the tip his chin. Clinical radiological examination revealed cause tract radiolucency as pulp necrosis associated apical periodontitis in mandibular left incisors. Additionally, a...

Objective: The aim of this study was to compare the amounts debris extruded apically with use different single file systems during endodontic retreatment. Material and Methods: 36 mandibular premolar teeth were prepared ProTaper Universal files up F3. At every instrument change, root canals irrigated 2 mL 5.25% NaOCl solution. After canal preparation, final irrigation performed using 5 17% EDTA followed by saline. dried paper point filled gutta percha AH Plus sealer. stored at 37 °C 100%...

Objective: The aim of this in vitro study is to assess the effect activation EDTA and chitosan by different irrigation systems on microhardness root canal dentin. Material Methods: A total 60 single-rooted extracted mandibular premolars were prepared randomly distributed into two groups (n=30) based final irrigant: Group 1, 0.2% chitosan; 2, 17% EDTA. Then, specimens both divided three subgroups (n=10) irrigant activation; Subgroup (Sonic), B (Ultrasonic) C (Conventional irrigation, control...
