The aim of the study was to characterize the surface chemistry, hydration capacity, topography and roughness of the root part of a hydrophilic sandblasted and acid-etched titanium dental implant (SLActive). Implants as received (SAR), after water rinsing (SAW) and after ultrasonication in water (SAU) were subjected to x-ray photoelectron spectroscopy (XPS) elemental and binding state analysis. Scanning electron microscopy plus energy dispersive x-ray microanalysis (SEM/EDX), reflection Fourier transform infrared microspectroscopy (RFTIRM) and hydration/ dehydration cycling by environmental scanning electron microscopy (ESEM), were performed in SAR, whereas SAU implants were subjected to 3D-optical profilometry and SEM...

BACKGROUND: Research into bleaching focuses on new products in order to minimize undesirable effects. This study evaluated the bleaching effectiveness of a new enzymatic-activated dentifrice. MATERIALS AND METHODS: A total of 20 volunteers were bleached with a dentifrice containing 5% lactoperoxidase and 3% carbamide peroxide applied three times a day for two minutes over 21 days. Color was recorded before and after the treatment using a spectrophotometer. CIELAB differences were calculated before and after treatment using the paired t test (P < 0...

Many treatment options are currently available for single tooth replacement, such as metal-ceramic, all-ceramic, direct or indirect fiber-reinforced composite fixed dental prostheses (FDPs) or implants. Inlay-retained FDPs could be indicated especially when adjacent teeth have preexisting restorations and where implant placement is not possible or not indicated. In such cases, indication of both metal-ceramic and fiber-reinforced composite FDPs has certain disadvantages. This paper describes the use of all-ceramic inlay-retained FDPs with zirconia frameworks, veneered with a press-on technique...

It is currently accepted that success in implant-supported restorations is based not only on osseointegration, but also on achieving the esthetic outcome of natural teeth and healthy soft tissues. The socalled "pink esthetic" has become the main challenge with implant-supported rehabilitations in the anterior area. This is especially difficult in the cases with two adjacent implants. Two components affect the final periimplant gingiva: a correct bone support, and a sufficient quantity and quality of soft tissues...

Interdisciplinary, multidisciplinary and comprehensive treatment plans are now part of everyday practice. The interaction between different specialists can provide patients with better, more conservative and more pleasing results. This case report shows the step by step of a multidisciplinary treatment plan and the rationale for each part of a process where conservative dentistry, periodontics, orthodontics, implant dentistry and prosthetics are involved.

Minimally invasive treatment modalities allow for the preservation of sound tooth substance. However, by limiting the preparation to the extent of a defect, the transition between restoration and natural tooth may be moved to more visible areas. The materials available for the restoration of a limited defect in the anterior area are either resin composite materials or porcelain. A patient was presented who asked for the replacement of a discolored filling on the maxillary right central incisor. Tooth preparation was limited to the extent of the old filling, and a porcelain partial veneer restoration was fabricated...

OBJECTIVES: The aim of this in vitro study was to evaluate the bleaching efficacy of high concentration bleaching agents activated by chemical or physical catalysts. MATERIALS AND METHODS: This study was divided into two parts. Part 1 evaluated the efficacy of tooth whitening after treatment with 35% hydrogen peroxide (Whiteness HP Maxx) that was activated by different light-curing units: halogen lamp (conventional and bleach mode) (Optilux 501C, Demetron/Kerr), LED first generation (Ultrablue IV, DMC), LED/diode laser (Ultrablue IV, DMC), LED second generation (Bluephase 16i, Ivoclar Vivadent), and no light source (control group)...

Although supervised night-guard bleaching has proved successful for whitening teeth, both mineral loss and tooth sensitivity are still common problems. The present study introduces a novel remineralizer as well as describes the utilization of a possibly low sensitivity supervised night-guard vital tooth bleaching technique. A 22% carbamide peroxide gel was mixed with the casein phosphopeptide-amorphous calcium phosphate-containing MI Paste. The peroxide/MI Paste mixture was prepared with 1 ml of each material until obtaining a homogeneous paste...

STATEMENT OF PROBLEM: Studies have measured the effectiveness of tooth bleaching, however there are very few studies that have measured the persistence in color change after a 6-month follow-up. PURPOSE: This study assessed the efficacy of the laser bleaching process using different regimens, and the persistence of color change over a 6-month period. METHOD AND MATERIALS: Sixty patients divided into three equal groups were subjected to bleaching using a diode laser with 34% hydrogen peroxide...

INTRODUCTION: The objective of this study was to evaluate the intra- and interdevice repeatability in different tooth regions using three color-measuring devices under clinical conditions. MATERIALS AND METHODS: Fifteen shade measurements (cervical, body, incisal) were recorded on 15 patients by one investigator using three color-measuring devices (VITA Easyshade compact, DeguDent Shadepilot, X-Rite ShadeVision). CIE Lab values were determined for all maxillary anterior teeth...

Esthetics is a topic that has become much discussed both in medicine and in dentistry. However, it should be questioned how reliable and reproducible the guidelines and protocols for esthetic procedures really are. This article will describe in detail the interactions between the musculoskeletal and masticatory systems. Dentists are frequently misled by their false interpretation of existing reference lines, without recognizing the true problem. The close relationship between skeletal and dental problems and their impact on the masticatory and musculoskeletal systems will be explained in this paper...

The esthetic rehabilitation of advanced periodontal cases remains a challenge, despite the numerous advances in treatment of periodontitis and regenerative therapies. Whilst understanding of periodontal diseases deepens with advances in cell biology, cell signaling, and genomic research, the restoration of the gingival tissues to anatomical norms remains a considerable challenge in advanced cases. The improvements in diagnosis and treatment of disease certainly enable successful management of disease and stabilization of the compromised and failing dentition...

The aim of this study was to assess the durability of bleaching results achieved with (1) 15% carbamide peroxide home bleaching and (2) 38% hydrogen peroxide in-office bleaching. A total of 231 extracted anterior teeth were randomly divided into three groups (n = 77 in each group) with comparable mean baseline L*-values (68.24 ± 0.8): a non-bleached control group A, a 15% carbamide peroxide group B (5 bleaching intervals of 8 hours), and a 38% hydrogen peroxide group C (3 intervals of 15 minutes). Durability of bleaching was assessed by comparing CIE-L*a*b* data after intervals of 2, 4, 12, and 26 weeks from baseline...

This study presents a technique for improving implant placements. As is widely known, a correct positioning is essential in restoration-driven implants, as well as in tilted implants in order to obtain satisfactory final functional and esthetic results. To this end, some authors have emphasized the importance of using a diagnostic and/or surgical guide to plan the exact implant position. In practice, one of the clinical problems faced is how to check the accuracy of the template prior to initiating the surgical phase...

UNLABELLED: The "smile line" is commonly used as a parameter to evaluate and categorize a person's smile. This systematic literature review assessed the existing evidence on the validity and universal applicability of this parameter. The latter was evaluated based on studies on smile perception by orthodontists, general clinicians, and laypeople. METHODS: A review of the literature published between October 1973 and January 2010 was conducted with the electronic database Pubmed and the search terms "smile," "smile line," "smile arc," and "smile design...

Bonded porcelain restorations are a predictable and durable treatment option with which not only esthetic appearance but also the strength and function of teeth can be re-established. One of the most important issues of today's dentistry is the preservation of sound enamel. Following biomimetic principles, employing minimally invasive applications and adhesive technologies are of paramount importance for successful restorations. The mock-up technique is advised for delicate removal of the required space for thin porcelain veneers minimally...

Achieving similar features to those on natural teeth is a common problem with esthetic restorations. Color matching is a fundamental procedure required to perform a predictable composite resin restoration. It is no longer enough to measure these criteria with conventional shade guides, which provide the hue and chroma, but do not take into account other dimensions of the tooth such as value, intensives, opalescence and characterizations. The present article presents a simple and effective technique for color selection using a digital photograph of the tooth and an image-editing program such as Adobe Photoshop or Picture Project...
