Closure of the surgical incision has been primary function sutures since their introduction. However, whatever type, they are known to carry bacteria, which can be a source infection. Five types sutures, Gut, Silk, Vicryl, PTFE, and Polyamide, were selected tested on ability aerobic anaerobic bacteria rated basis forming colony-forming units (CFUs). Aerobic grown around gut showed minimum CFUs (≈30 × 104/suture). Though very less growth was seen among all suture materials, it maximum Vicryl...

One hundred twenty extracted with one or more completed roots were scanned Micro-CT. Three fixed heights determined at axial level analysed criteria were: dentine thickness, diameter canals, presence lateral isthmus number foramina. Vertucci's classification was also studied. Vertucci Type I prevalent in palatal mesio-buccal superior molar distal...

Apical periodontitis is a common inflammatory condition associated with root canal treatment (RCT) failure. The quality of the three-dimensional seal critical to success treatment. Bioceramic sealants, such as Neosealer Flo, offer biological advantages osteoconduction, biocompatibility and sustained calcium ion release, which may improve apical healing. aim this study was compare AH Plus Flo in terms postoperative pain, extrusion periapical A single-blind, randomised clinical trial conducted...

The aim of the study was to evaluate chemical composition crushed, extracted human teeth and quantity biomaterial that can be obtained from this process. A total 100 teeth, due trauma, decay, or periodontal disease, were analyzed. After extraction, all classified, measured, weighed on a microscale. crushed immediately using Smart Dentin Grinder machine (KometaBio Inc., Cresskill, NJ, USA), device specially designed for procedure. tooth particles 300⁻1200 microns, by sieving through special...

Manipulation of implant surface characteristics constitutes a promising strategy for improving cell growth and tissue response on variety materials with different topographies. Mesenchymal progenitor cells capacity to respond titanium stimuli differentiate into osteoblasts were used perform comparative tests between two topographies, including their functional interaction pre-osteoblasts directly seeded onto the implants. Functional analysis nanostructured surfaces was performed by in vitro...

The physical characteristics of an implant surface can determine and/or facilitate osseointegration processes. In this sense, a new with microgrooves associated plus double acid treatment to generate roughness was evaluated and compared in vitro vivo non-treated (smooth) treatment. Thirty disks thirty-six conical implants manufactured from commercially pure titanium (grade IV) were prepared for study. Three groups determined, as described below: Group 1 (G1), where the samples only machined;...

Background and objectives: To evaluate whether sinus augmentation, using a minimally invasive implant device, via non-submerged surgical approach, might negatively influence the outcome. Materials Methods: A retrospective cohort study was conducted by evaluating patients' files, classifying them into two groups. Fifty patients (22 men 28 women) were included in study, 25 each group. The use of an device based on residual alveolar ridge height for radiographic evaluation, insertion torque,...

Surface treatments of Ti in the dental implant industry are performed with aim in-creasing its bioactivity and osseointegration capacity. Chitosan (Cht) is a polysaccharide that has been proposed as promising biomaterial tissue engineering bone regeneration, due to ability stimulate recruitment adhesion osteogenic progenitor cells. The our preliminary study was evaluate, by micro-computed tomography (micro-CT), formation around Cht-coated implants compare them conventional surface-etched...

Osseointegration capacity and good mechanical behavior are key to the success of dental implant. In many investigations, comparisons properties made using different implant designs therefore results can be influenced by macrodesign this work, studies were carried out with same model roughness materials-commercially pure titanium (grade 4) zirconia. For purpose, 80 smooth passivated (Ti), zirconia (ZrO2), rough (Ti-R) implants used. The samples characterized their roughness, wettability,...

The aim of this study was to evaluate the comfort children and adolescents with conventional full-arch dental impression methods compared two intraoral scanners (iTeroTM PrimescanTM). Methods: A monocentric, analytical, controlled crossover designed compare digital PrimescanTM) in teenagers. Patient evaluated using a 100 mm VAS scale adapted Spanish for children. descriptive analytical statistical method conducted confidence level 95% (p ≤ 0.05) asymptotic or bilateral significance.

In this work, the physicochemical properties and in vitro bioactivity cellular viability of two commercially available bovine bone blocks (allografts materials) with different fabrication processes (sintered not) used for reconstruction were evaluated order to study effect microstructure behavior. Scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectrometry, mechanical resistance blocks, mercury porosimetry analysis, bioactivity, cell proliferation performed...

The aim of this work was to analyze and compare the effect bone morphogenetic protein-7 on biological parameters related implant osseointegration in an experimental animal model. Sixteen dental implants were placed tibias four randomly selected minipigs for following surface treatments: Group A: conventional treatment by SLA (n = 8) B: with carboxyethylphosphonic acid 8). animals sacrificed one month after placement a histomorphometric study performed evaluation bone-to-implant contact,...

Background and Objectives: Implant stability in vivo is contingent on multiple factors, such as bone structure, instrument positioning implant surface modifications, diameter, length. Resonance-frequency analysis considered a non-invasive, reliable, predictable, objective method by which to evaluate stability, due its correlation with bone-to-implant contact. The purpose of this study was the effect length primary secondary single-implant crown rehabilitations, measured resonance-frequency...

Objectives: The objective of this cross-sectional study was to evaluate the vertical bone gain achieved after sinus lift procedure with beta-tricalcium phosphate (β-TCP) used as a substitute and simultaneous implant placement.

A postextraction socket becomes a clinical challenge due to the fact that series of changes associated with bone remodelling and resorption occur after extraction, which limits aesthetic functional prognosis implant-supported rehabilitations. It has been studied use autologous tooth-derived graft (ATDG) regenerative properties could therefore be useful for solving this type problem. There is no consensus in scientific literature on standardized protocol tooth. Therefore, aim present study...
