Filter by:This study aimed to evaluate the 12-month clinical performance of direct composite restorations by placing polyethylene fibers in different directions in endodontically treated posterior teeth. In this clinical study, Clearfil SE Bond (Kuraray/Japan) adhesive system, G-aenial Universal Injectable (GC/Tokyo, Japan), G-aenial A'chord (GC/Tokyo, Japan) composites, and polyethylene fiber (Ribbond, USA) were used. In the restoration of the teeth included in the study, polyethylene fiber was placed in different directions according to the amount of remaining tooth tissue and cavity preparation. The restorations were divided into three groups according to the direction of fiber placement ('O' shape, mesiodistal I shape, buccolingual I shape) (n=12). Restorations were evaluated according to modified USPHS criteria in 1st week and 6th months from the placement date. The Chi-square test was used for statistical analysis of the difference between the groups, and the Cochran Q test was used for the significance of the difference between time-dependent changes within each group (p<0.05).
The clinical performance of two different materials in endodontically treated teeth produced with CAD/CAM system will be evaluated and compared. After obtaining a signed informed consert form from all the patients, all restorations will be placed by a single clinician. All endocrown restorations will be produced using the same CAD/CAM system. 52 restorations will be fabricated using Lava Ultimate (LU, 3M Espe, Seefeld, Germany) blocks and 38 restorations will be fabricated using Celtra Duo (CD, Dentsply Sirona, York, PA, USA) blocks. All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using modified United States Public Health Service (USPHS) criteria after baseline, 6,12,36, 48, 60 months. Descriptive statistics will be performed using Chi-square and Fisher exact test.
The goal of this randomised clinical trial is to evaluate the effect of cryotherapy on postoperative pain after primary and secondary root canal treatment. The main question[s] it aims to answer are: - Dose cryotherapy help reduce postoperative pain after primary root canal treatment. - Dose cryotherapy help reduce postoperative pain after secondary root canal treatment. Participants will be randomly divided to receive either cryotherapy or irrigation with normal saline and the effect between the two groups in terms of postoperative pain will be compared after primary and secondary root canal treatment.
This investigation will be a longitudinal clinical trial to study the association of preparation design on the internal and marginal adaptation of the resulting restorations and the long-term clinical performance of chairside CAD/CAM endocrown restorations. Advanced lithium disilicate chairside CAD/CAM endocrowns (CEREC Tessera/Dentsply Sirona) will be adhesively bonded using a selective enamel etch technique with a universal adhesive (Prime and Bond Elect/Dentsply Sirona) and a dual cure resin adhesive cement (Calibra Ceram/Dentsply Sirona). All restorations will be followed over five years of clinical service.
The use of full cuspal coverage restoration for the management root treated teeth was advocated by many clinical studies and supported by systematic reviews. However, most of the studies did not take into account the amount of tooth structure remaining before providing cuspal coverage. The strength and fracture resistance of the tooth has been shown to be positively correlated with the amount of tooth structure remaining. A more conservative treatment option could be selected for a root treated tooth with good amount of remaining tooth structure such as direct restorations. The aims of this randomized clinical trial is to compare the survival and success of root treated teeth with occlusal cavities and at least three intact axial walls, when restored through the use of indirect full cuspal coverage restorations vs direct composite resin restorations.
Verify, through a randomized double-blinded clinical trial, the influence in the performance of pulpectomies in primary teeth, based on two working length methods, electronic and radiographic.
