Specific staining of the extracellular matrix components is especially helpful in studying tissue remodeling, particularly case connective pathologies. As developed by Junqueira and colleagues 1979, specific Picrosirius red one most important stains to study collagen networks different tissues. Under polarized light, bundles appear green, or yellow, are easily differentiated from black background, thus allowing for quantitative morphometric analysis. point out, many studies use color...
Dental histology is a field that has been studied since the early 19th century. Most of techniques used have based on white-light microscopy or histological staining, more recently immunohistochemical staining. With advent lasers coupled to confocal microscopy, Raman spectra can be measured in large numbers create detailed chemical atlas human tooth, offering new insights into its composition and structure. A total twenty teeth, with 5 teeth from each type premolar, molar, incisor canine...
Abstract The purpose of this study was to investigate the relationship between osteoblastic cells behavior and biotribocorrosion phenomena on bioactive titanium (Ti). Ti substrates submitted anodic oxidation etching treatments were cultured up 28 days with MG63 osteoblast‐like cells. Important parameters in vitro bone‐like tissue formation assessed. Although no major differences observed surfaces topography (both rough) wettability hydrophobic), a significant increase cell attachment...
The use of the ala-tragus line (ATL) to orient occlusal plane (OP) is controversial because there a lack agreement on exact points reference for this line. This study determined relationship between natural OP and ATL which was established by using inferior border ala nose (1) superior tragus (ATL1), (2) tip (ATL2), (3) (ATL3).Lateral cephalometric radiographs were taken each subject standard method tracings obtained acetate paper show three lines. measured subject. Mean deviation values...
Heparan sulfate glycosaminoglycans are key players of tissue repair and can be regarded as useful compounds for regenerative medicines. Unfortunately, their therapeutic uses face many technical, industrial, regulatory hurdles due to animal origin. So, some non-animal sulfated polysaccharides mimic heparan properties offer interesting solutions replace them. Among them, dextran derivatives, seaweed polysaccharides, or marine bacterial the best known have demonstrated pro-regenerative...
Different techniques for the enucleation of jaw cyst lesion in oral and maxillofacial regions have been proposed, including bone lid technique. The purpose this case report is to describe a cystic lesion, approached with technique performed using piezoelectric device, an 8-month clinical radiographic follow-up. A 14-year-old male patient was treated suspicious detected on panoramic radiograph. concerned area surgically accessed, radiographically predetermined bony window drawn, beveled...
ABSTRACT Background The periimplant bone level has been used as one of the criteria to assess success dental implants. It documented that supporting two-piece implants undergoes resorption first following second-stage surgery and later on further abutment connection delivery final prosthesis. Objective aim this multicentric randomized clinical trial was evaluate crestal around internal using a new surgical protocol aims respect biological distance, relying benefit friction fit (test group)...
The presence of lysozyme in human gingiva has not previously been demonstrated. In this study, we looked for evidence the potential role as a protector gingival elastic fibres. objective study was also to determine ex vivo susceptibility hydrolysis fibres from patients with or without periodontal disease by leukocyte elastase and cathepsin G.Using tissue sections eight control, 10 gingivitis periodontitis patients, evaluated area fraction occupied (after selective staining) use automated...
The aim of this study was to assess lower third molar space using four different radiographic reconstructed Cone Beam Computed Tomography (CBCT) images: orthopantomogram, lateral cephalogram, multiplanar CBCT and a newly introduced three-dimensional (3D) simulation technique.The scans 32 individuals (20.97 ± 2.152 years) with total 50 molars were collected analyzed. ratio between the necessary available for calculated on each image. Repeated-measure analysis variance followed by multiple...
The hepatitis B virus (HBV) is a serious occupational hazard for healthcare workers, including dentists. purpose of this study to assess dentists' knowledge, attitude, and practice (KAP) with respect vaccination.
Aim:The aim of the present work was to explain poor biointegration acellular dermal xenogeneic matrix, leading an unfavorable gingival healing following a grafting procedure for treatment soft tissue deficiencies.Background: Numerous works have demonstrated successful use matrix (ADM) in augmentation procedures.However, spare human investigations reported adverse outcomes at microscopic level.Case description: Three patients showing various deficiencies (recession, thickening) requiring were...
Tooth extraction causes major changes to the ridge, rendering implant placement a more challenging procedure. Proper management of socket is necessary ensure sufficient bone and soft tissue for successful implant-supported prosthesis. This article presents practical approach autologous hard grafting. A graft harvested in one piece from maxillary tuberosity stabilized socket.
