Different surgical approaches have been proposed to treat peri-implantitis defects with limited effectiveness and predictability. Laser has as an effective tool assist in bacterial decontamination modulating peri-implant tissue inflammation. The aim of this pilot clinical trial was evaluate the adjunctive benefits Er:YAG laser irradiation for regenerative therapy peri-implantitis-associated osseous defects.Twenty-four patients diagnosed a radiographic infrabony defect were randomized into...

Despite the increasing demand for fiber-reinforced composite (FRC) posts, their bonding to root canals is still subject debate. Endodontic sealers may affect bond strength between fiber posts and canal dentin. Aim: To compare effects of different on post strength. Methods: Sixty teeth were divided into 4 groups according obturation method: GI, gutta-percha without any sealers; GII, AH26 resin-based sealer; GIII, RealSeal point sealer, GIV, Guttaflow. Fiber cemented canals. Specimens...

This study aimed to assess the Scanning Electron Microscope (SEM) analysis of tooth surface irradiated by erbium:yttrium-aluminum-garnet (Er:YAG) laser with various parameters.Number 25 extracted human third molars free caries were used in this study. The teeth put into 5 groups for irradiation as follows: group 1 (power: 0.5 W, Energy: 50 mJ); 2 100 3 1.5 150 4 200 2.5 250 mJ). All samples prepared repetition rate 10 Hz and duration 230 μs, using a non-contact handpiece at distance mm....

Abstract Aim Since there is limited study to assist in an evidenced‐based decision whether extract or preserve a structurally compromised tooth, the aim of this retrospective was investigate long‐term survival rate tooth preservation after crown lengthening procedure (CLP) and restorative treatments. Methods Electronic paper chart patients received CLP our graduate clinic from 1990 2015 were reviewed. Statistical analysis done using Cox regression Kaplan–Meier estimator. Results A total 766...

Introduction: Today, bleaching is a routine noninvasive alternative for treatment of discolored teeth. The aim this study was to determine whether conventional or laser activated predispose teeth develop caries not. Methods: Sixty human molars were mounted on acrylic cylinders and their Knoop microhardness (KHN) as well DIAGNOdent (DD) values recorded. They divided into 4 experimental groups; G1) with 40% hydrogen peroxide gel, G2) Diode assisted same G3) Nd:YAG the G4) control group. After...

Rehabilitation of periodontal support is the main goal therapies for periodontitis. Hand instrumentation with curettes, piezoelectric ultrasonic scalers and lasers, such as Er,Cr:YSGG, are used this purpose. This study was designed to evaluate human gingival fibroblast viability attachment root surface after modification mentioned therapeutic alternatives. Lasers showed significantly lower cell 72 hours compared hand ultrasound, probably due more irregular surfaces treatment.

Rapid maxillary expansion (RME) is performed on transversely deficient maxilla. As all orthodontic treatments, retention important in maintaining therapeutic outcomes. Fixed /removable retainers are used post-RME causing hygiene and compliance problems. Given photobiomodulation's positive effects the quantity quality of bone regeneration, its effect relapse was studied. Thirty Sprague Dawley rats were randomly divided into group R, non-irradiated RME-treated (n = 12), P, irradiated 12) C,...

Introduction: No one can cast a shadow of doubt on the fact that temperature is key element in dentistry. Temperature control enable dentists variety clinical fields to perform more convenient. Frozen slab known method for manipulating before mixing cements. But lack precise and infection bolded. Clinical innovation: The present apparatus determines routine dentistry tasks; namely restorative dentistry, prosthesis even injections. This device capable whether heating or cooling materials...

Introduction Augmenting the edentulous anterior mandible can be a challenge. This case report describes novel technique that combines bone reduction and buccal contouring using an autogenous block graft. Case Presentation A patient presented with conventional mandibular denture had poor retention. The deficient ridge could not support dental implants without hard tissue augmentation. was reduced vertically osteotomy to allow harvest of graft for horizontal After 8 months, were placed in...
