Summary Introduction Cutaneous hyperchromias are disorders of skin pigmentation involving increased melanin production and its irregular accumulation in cells. The use sunscreens is fundamental for the control by reducing stimulation pigmentation, as synthesis mainly stimulated solar radiation. Many studies have demonstrated that visible light can induce significant damage. Considering effects light, effective photoprotection should not be limited only to UV protection but also involve...

We selected 60 patients using bimaxillary conventional dentures who needed replace their During anamnesis, we collected demographic data applied Oral Health Impact Profile for Edentulous Patients (OHIP‐EDENT) questionnaire (PERCEPTION). Before installation prostheses, responded OHIP‐EDENT questionnaire, on day...

Ceramics have been widely used for esthetic and functional improvements. The resin cement is the material of choice bonding ceramics to dental substrate it can also dictate final appearance strength restoration. correct use wide spectrum luting agents available depends on tooth substrate. This article presents three-year clinical results a 41 years old female patient B.H.C complaining about her unattractive smile. Two all-ceramic crowns two laminates veneers were placed in maxillary incisors...

Abstract – The teeth most commonly affected by trauma are the maxillary central incisors. frequent types of traumatic dental injuries to permanent enamel fractures, and dentine fractures with pulp involvement. This article describes three clinical cases different levels traumatized incisors several cosmetic approaches for recovery esthetics masticatory function, as well social/psychological aspects treatment. All involved young adult men. involve dentin exposure, exposure associated root...

The presence of porosities at the dentin/adhesive interface has been observed with use new generation dentin bonding systems. These tend to contradict concept that etching and hybridization processes occur equally simultaneously. Therefore, aim this study was evaluate micromechanical behavior hybrid layer (HL) voids based on a self-etching adhesive system using 3-D finite element (FE) analysis. MATERIAL AND METHODS: Three FE models (Mr) were built: Mr, specimen (41x41x82 μm) regular perfect...

The aim of this study was to evaluate stress distribution on the peri-implant bone, simulating influence Nobel Select implants with straight or angulated abutments regular and switching platform in anterior maxilla, by means 3-dimensional finite element analysis. Four mathematical models a central incisor supported external hexagon implant (13 mm × 5 mm) were created varying (R, S, switching) (S, A, 15°). using Mimics 13 Solid Works 2010 software programs. numerical analysis performed ANSYS...

Purpose In view of reports in the literature on benefits achieved with use platform switching, described as an implant a larger diameter than abutment diameter, goal being to prevent (previously) normal bone loss down first thread that occurs around most implants, thus enhancing soft tissue aesthetics and stability need for inclination due anatomy some cases, aim this study was evaluate stress distribution peri-implant bone, by using three-dimensional finite element analysis simulate...

Summary Background Cutaneous hyperchromias are disorders of skin pigmentation involving an increase melanin production and its irregular accumulation in cells. It is known that the use sunscreens helps to prevent changes pattern, but structural morphological alterations occur different types hyperpigmentations need better elucidation. Objective To assess influence solar exposure protection habits on pattern using reflectance confocal microscopy ( RCM ). Methods Forty volunteers aged 18‐39...

Abstract Aim The aim was to evaluate the biomechanical behavior of supporting bony structures replanted teeth and periodontal ligament ( PDL ) adjacent when orthodontic wires with different mechanical properties are applied, three‐dimensional finite element analysis. Materials methods Based on tomographic microtomographic data, a model anterior maxilla corresponding (tooth 13–tooth 23) generated simulate avulsion replantation tooth 21. were splinted wire (Ø 0.8 mm) composite resin. elastic...

International Endodontic Journal , 45 146–155, 2012. Abstract Aim To evaluate mechanical behaviour dentine/cement/post interface a maxillary central incisor using finite element method and to compare stresses exerted conventional or post cementation techniques. Methodology Four models were created...

There are few studies that characterize the non-pigmented hair compared to pigmented hair.Furthermore, it is important evaluate how natural process of aging influences quality life in women.For this purpose, a questionnaire was applied impact greying and appearance alterations on women´s self-esteem.The satisfaction level volunteers regarding their structure conditions such as shine, strength smoothness were also evaluated.Mechanical properties, elasticity traction rupture measured using...

Between April 1984 and November 1986, 126 faeces samples were collected from puppies bitches in a kennel examined for Yersinia species; 45 (35.7 per cent) of them positive. Thirty-eight isolates Y enterocolitica, five frederiksenii two intermedia. Twenty-one the enterocolitica belonged to serogroup 0:3 17 these L-sorbose negative; all puppies. One strain L-sorbose-negative resistant antimicrobial agents showed four different patterns resistance (ampicillin, cephalothin tetracycline;...

To evaluate the stress behavior of ceramic fragment restoration, varying thickness cement layer and intraoral temperature variation. A solid model a upper lateral incisor was obtained defect at enamel distal/incisal edge restored with fragment. Based on this initial model, 4 different models (M) were built: M1 – absence (CL) (0 μm thickness); M2 CL an uniform 50 μm; M3 margin ceramics 100 in inner area far from margins; M4 200 margins. The environment changed 5 °C to increments. finite...

IgA nephropathy of 5-years' duration in a 14-year-old boy evolved into diffuse crescentic glomerulonephritis with rapid progression to terminal renal failure. This report suggests that rare cases may develop an aggressive course.

Purpose: To evaluate the clinical outcomes of minimally invasive ceramic restorations executed by dentists with different levels experience. Methods: Sixteen professionals were divided into 4 groups according to their experience levels. These included G1: up 2 years since graduation, G2: 2-5 years, G3: 5-10 and G4: more than 10 years. All trained follow same standardized protocol, but unaware research objectives. A single evaluator followed treatments recorded complications errors that...

Post-Inflammatory Hyperpigmentation (PIH) is a common pigmentary disorder in patients with pigmented skin.Histological and clinical exams have been used for the diagnosis of PIH to determine correct treatment.However, Reflectance Confocal Microscopy (RCM) has potential replace these methods since it noninvasive advanced technique higher diagnostic accuracy than dermatoscopy.The aim this study was characterize correlate main aspects observed by RCM macroscopic characteristics acne-related...
