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.
Problem statement: The post-operative pain after endodontic treatment. aim of study: The study is aiming to compare postoperative pain after submucosal cold saline injection (submucosal cryotherapy) (SMC) versus intra-canal cryotherapy (ICC) in mandibular single rooted premolars with symptomatic irreversible pulpitis with symptomatic apical periodontitis (SAP). The material and methods: Subjects and methods: sixty patients will be randomly divided into three groups: the SMC group, the ICC group, and the control group. The patients' postoperative pain will be recorded at 12, 24, and 48 hours postoperatively by questioning them. Quantification of substance P will be done using an ELISA test from peri-radicular fluid swab.
The objective of this double-blind, randomized controlled clinical study will be to evaluate the effect f PBM on pain after endodontic instrumentation in the single-session treatment of upper molars and premolars. The sample will consist of 58 participants treated endodontically in a single session and randomly allocated to the PBM Group with conventional treatment with photobiomodulation and the Control Group with conventional treatment with simulation of PBM. The primary variable of the study will be the evaluation of spontaneous pain immediately before treatment, and the participant will be reassessed for postoperative pain 24 hours after instrumentation using the visual analog scale (VAS). As secondary variables, pain prevalence, pain at 4h, 8h, and 12h after the procedure, palpation pain (vestibular and lingual), and percussion pain (vertical and horizontal) will be assessed 24 hours after the procedure, as well as the number of necessary analgesics (paracetamol) and the impact of oral health on quality of life evaluated by the OHIP 14 instrument.
Pulpitis is the pulpal inflammation in response to irritants which are either microbial, chemical, or physical (mechanical and thermal) in origin. Clinically, pulpitis is termed as reversible or irreversible, whereas histologically, it is described as acute, chronic or hyperplastic . Pulpitis is considered reversible when the pulp can heal following conservative management . For such cases, a coronal pulpotomy is considered as a definitive treatment option having 78% to 90% of success rate . In irreversible pulpitis (IP), the pulp is not capable of healing, thus it is treated traditionally complete pulpectomy.
Aim: Evaluation of the effect of different obturation techniques on postoperative pain level and radiographic healing on non-surgical endodontic retreatment (NSER) applied in a single visit in teeth with single root canal and apical periodontitis (AP). Materials and Methods: 63 teeth with single-root canal and AP from 50 systemically healthy patients (mean age 34.19±9.75 years; 27 women, 23 men) were included in the study. Residual root canal filling materials were removed with retreatment files. All teeth were prepared using rotary files . The teeth were randomly divided into three groups according to the obturation technique; cold lateral compaction (CLC), continuous wave compaction (CWC), and gutta-core (TGC). Restorations are completed using direct composite resin in the same visit. In all cases, pain status were evaluated using the Numerical Pain Rating Scale (NRS) at preoperative, postoperative, 3rd hour, 24th hour, 48th hour, and 7th day. Periapical index (PAI) scores were recorded on preoperative and postoperative 6-month on the periapical radiographs for cases. Data were analyzed as statistically. Significance level was determined as p < 0.05.
The sample size will be divided between two groups, Group A pulpectomy will be done using single rotary file in primary molars and group B pulpectomy will be done using manual K file system. follow up of the patients and clinical and radiographical success rates of cases will be seen.
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.
Rehabilitation of anterior endodontically treated teeth with significant coronal damage has been problematic. Adopting endocrown design to treat teeth with this condition is still under investigation. To address this issue, the USPHS criteria were adopted to assess the anterior endocrown restorations manufactured using various ceramic materials and cemented with different protocols.
This randomized controlled trial is to clinically assess and compare impression quality of polyvinylsiloxane impression material using one step (experimental) and two step (control) impression techniques and its effect on marginal fit of prosthesis and proximal contact of prosthesis.
