BACKGROUND AND AIM The aim of this in vitro study was to compare Er, Cr: YSGG laser with ultrasonic preparation on the seal of retrograde cavities. MATERIALS AND METHODS Twenty-eight maxillary anterior teeth were used in this study. After removing the crowns, the canals were prepared with the step-back technique and filled with guttapercha. Three millimeters below the apex; each root was cut ...

AIM To evaluate and compare the efficacy, cleaning ability of hand and two rotary systems in root canal retreatment. METHODOLOGY Sixty extracted premolars were retreated with following systems: Group -ProTaper Universal retreatment files, Group 2-ProFile system, Group 3-H-file. Specimens were split longitudinally and amount of remaining gutta-percha on the canal walls was assessed using direc...

This study evaluated the antibacterial activity of Rosmarinus officinalis extract and its potential for disinfecting guttapercha (GP) cones. In the first experiment, a hydro-alcoholic extract of Rosmarinus officinalis (leaves) in a dilution ratio of 10% m/v was tested against Enterococcus faecalis by using the disk diffusion method. Positive and negative controls were 70% cereal alcohol and ant...

Introduction : Post and core are needed to regain retentions and functions after endodontic therapies. Also, risk of cross contamination from dental prosthesis is so high. The aim of this study was to compare dimensional changes of acrylic resin patterns (ARP) in three different storing environments. Materials and methods : conventional root canal therapy was done on one first premolar tooth an...

The aim of this study was to examine and compare vertical forces exerted during root canal obturation with the cold lateral condensation technique, Thermafil technique and ProTaper guttapercha. Fourty-five single-rooted permanent teeth were used in the study. All specimens were instrumented using the ProTaper rotating technique and were randomly divided into three experimental groups (n = 15 pe...

Aim: To evaluate the strength of an endodontically treated tooth after preservation of peri-cervical dentin and soffit. Methodology: 30 human molars having well developed cusps and morphology were extracted for periodontal reasons were included in this study. They were divided in two groups. In gp. A, ClarkKhademi access was made and endodontic treatment was carried out with 2% NiTi K-files and...

background: the aim of this study was to evaluate and compare the in vitro biofi lm forming capacity of enterococcus faecalis on gutta-percha points disinfected with four disinfectants. materials and methods: a total of 50 gutta-percha points used in this study were divided into four test groups based on disinfectant (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, 20% neem, 13% benzalko...

Objectives: Due to the continuous development of invasive dental procedures, presently we encounter a permanent growing of medical complications, like protrusion of foreign bodies into the maxillary sinus during therapeutic maneuvers on the superior dental arch. Plus that we can find neglected foreign bodies in the maxillary sinuses after ENT surgical procedures. With this clinical study we eva...
