Filter by:Nowadays Endocrowns are classified as conservative treatment modality for restoration of Endodontically treated teeth in which pulp chamber is used as a retentive resource. With the advancement in technology in the field of adhesive dentistry its use is increasing day by day in clinical practice. Acid Etchable ceramics such as lithium Disilicate based ceramics are the gold standard ceramic material used for Endocrowns. The Etchable property and the translucent character of lithium Disilicate enhance strength and esthetic property. A new material CERASMART (Force Absorbing Flexible nano ceramic CAD/CAM block) contain high density of ultrafine glass particles with 71 wt% filled nano-composite. It combines high strength and unique aesthetics. full homogeneous and even distribution of nano ceramic network lead to unique physical properties for cerasmart . Uniform scuttle (very short inter-particle distance) of silanated and bonded particles is key to delivering CERASMART's™ with high strength and acceptable level of marginal adaptation. So, it can perfectly use in posterior, anterior, inlay, onlay, and implant restorations and also enables minimum tooth reduction for more conservative restoration. Awad et al (1) found that Cerasmart showed significantly higher flexural strength and modulus of elasticity, with lower flexural modulus values compared to other groups. Also, result in smoother margins compared with other types of ceramic. So, present research will evaluate patient satisfaction, bonding properties and marginal adaptation
The aim of this study is to evaluate chipping and the degree of natural enamel loss opposing to monolithic zirconia compared to veneered zirconia restoration.
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.
The pulp necrosis of permanent immature teeth implies the interruption of the root formation and apical closure. Diode lasers have been used in many areas of dentistry, with tendency of good results in canal and dentine disinfection. The bactericidal effect of high-power lasers is based on dose dependent heat generation. Its antimicrobial effectiveness against diverse microorganisms has already been demonstrated. Photodynamic therapy (PDT) is a two-step therapeutic approach starting with the application of a photosensitizing agent and followed by irradiation with light energy that is spectrally matched to activate the drug. The balance between disinfection and the creation of an intracanal microenvironment conducive for the proliferation of stem cells requires further investigation. Aims of study are to compare the time required to obtain the clinical healing and the disappearance of clinical symptoms, and absence of periapical radiolucency, by using PDT and diode laser, with standard disinfection alone; to assess specificity of microbial load in permanent immature teeth, and root canal disinfection ability of PDT and diode laser, in compare with standard disinfection alone.
Objective: To evaluate the immediate and mediate outcomes of endocrowns and onlay ceramic restorations with glass fiber pin in endodontically treated teeth. Material and methods: A randomized controlled clinical trial, a double-blind (patient and examiner) is conducted by one trained and calibrated operators who perform all restorative procedures. The restorations are evaluated longitudinally by a blind and calibrated examiner using the USPHS. A total of 20 patients will be randomly assigned to each group for a total of 40 patients. The randomization sequence will be generated (www.sealedenvelope.com) and to ensure the confidentiality of the allocation, this will be used opaque, sealed and numbered envelopes in series. These will be kept with an independent researcher for the moment of inclusion of the subjects. In the group of onlays, the teeth receive a fiberglass pin in the main root canal and composite resin filling. In the group of endocrown, only the restoration fill the pulp chamber. The parts are milled in IPS e-max CAD (Ivoclar Vivadent) and cemented with the Multilink cementation system (Ivoclar Vivadent). The immediate clinical (focused in restoration and patient) and mediate (radiographic and clinical) outcomes will be compared between the groups. Survival and success rates will be defined in 24 months. Survival will be established by Kaplan-Meier survival curve and log-rank can be conducted to identify as variables associated with as failures over time. Multivariate analysis with the Cox regression models will be condutcted for the determination of failure predictors. For all analyzes, the significance value will be adjusted to 5%.
Aim: The aim of this prospective study was to evaluate the treatment outcomes of regenerative endodontic technique (RET) for the management of traumatised non-vital immature teeth in children. Methodology: This study aims to recruit 25-30 healthy children with traumatised non-vital immature upper incisors to be treated with bi-antibiotic regenerative endodontic technique. Patients will be reviewed clinically at 3m,6m,9m,12m,2y,and 3 years and radiographically at 3m,9m, 2y,and 3 years. One operator will undertake all treatments, clinical reviews and standardised radiographic exposures. Radiographic analysis will be carried out by two calibrated experienced clinicians. Standardised photographs will be taken at 3m,12m,2y,and 3 years and crown colour changes will be assessed using a standardised validated methodology.
The aim of this study was to evaluate and compare postoperative pain and overextension of root canal filling after root canal treatment using a carrier-based obturation system and two different sealers. In this prospective randomized clinical trial, 160 mandibular premolars and molars in 160 patients were treated. Patients with vital and devital teeth were assigned to four groups using a randomized block design with block sizes of 10 patients each. The groups were composed of devital teeth with periapical lesions treated with iRoot SP sealer, vital teeth treated with iRoot SP sealer, devital teeth with periapical lesions treated with AH Plus sealer, and vital teeth treated with AH Plus sealer. In single visits, a single operator prepared root canals and filled them with sealer using the carrier-based obturation technique. Radiographs were taken and obturation length was recorded. Patients recorded pain scores use of Visual Analogue Scale and frequency of analgesic intake at baseline and 0-6, 6-12, 12-24, and 24-72 h..
To evaluate the incidence and severity of postoperative pain after root canal therapy of necrotic teeth in one appointment versus two appointments using Protaper next instrument.
The purpose of this clinical study was to compare the effectiveness of passive ultrasonic irrigation with that of traditional syringe irrigation on the removal of bacteria and endotoxin (lipopolysaccharide [LPS]) from root canals.
The aim of this study is to compare the postoperative pain after root canal treatment following irrigation by endodontic needle, sonic and passive ultrasonic irrigation techniques.
