As the demand for an esthetically satisfactory smile has increased, interest in less invasive procedures, such as composite restoration and tooth bleaching, has also increased. Composite resins exhibit several optical properties, including fluorescence, which are intended to mimic the natural dentition. The aim of this study was to evaluate the effect of hydrogen peroxide (HP) bleaching protocols for home and in-office applications on the fluorescence of composite resins. Sixty composite resin specimens (shade A2) were divided into 2 groups of 30 each according to the material type (groups R1 and R2 were made up of 4 Seasons and Opallis specimens, respectively)...

OBJECTIVES: To our knowledge, there is no study regarding the effects of facial type (short face or long face) on the esthetic perception of smiles as related to the amount of tooth and gingival display. MATERIALS AND METHODS: Four photographs from two long- and two shortfaced females with posed smiles were prepared and, with altering the amount of tooth display, 5 photos for each of them were produced. These photos were given to 62 dentists and 69 laypersons to rate the images...

This study aimed to evaluate whether preheated resin-based flowable restoratives would show increased hardness and softening susceptibility after an early cariogenic challenge. Fluroshield- Yellowed, Bioseal, Wave, Master Flow, Fluroshield-White, Conseal F, Filtek Z350 Flow, and Opallis Flow were tested. Preheating was performed using a microwave device. Five specimens of each preheated or room temperature material (n = 5) were fabricated. Hardness was assessed before and after a cariogenic challenge. The analysis was done by two-way analysis of variance (ANOVA) with repeated measures (cariogenic challenge) and Tukey's test for multiple comparisons (...

BACKGROUND: The need for proper framework support for the veneer porcelain in fixed partial dentures (FPDs) has been well documented. The aim of this study was to compare the variations of the support provided by frameworks designed directly on the computer, or indirectly through scanning a wax pattern. MATERIALS AND METHODS: For each of the six upper anterior FPDs that were involved in the study, prior to milling one framework was designed conventionally in wax and scanned and another one was directly digitally designed...

PURPOSE: The purpose of this study was to evaluate the esthetic result of monophasic zirconium dental implants, placed in the highly esthetic areas of the jaws. MATERIAL AND METHODS: In this case series the results of 12 monophasic zirconium dental implants placed in highly esthetic areas of 8 patients (6 male and 2 female). For each implant the Pink Esthetic Score (PES) and the White Esthetic Score (WES) were evaluated. All implants were inserted in fresh postextraction sites...

UNLABELLED: In case of severe dental erosion, the maxillary anterior teeth are often particularly affected. Restoring such teeth conventionally (ie, crowns) would frequently involve elective endodontic therapy and major additional loss of tooth structure. A novel, minimally invasive approach to restore eroded teeth has been developed and is currently being tested in the form of a prospective clinical trial, termed The Geneva Erosion Study. To avoid crowns, two separate veneers with different paths of insertion have been used to restore the affected anterior maxillary teeth, regardless of clinical crown length and amount of remaining enamel...

Nowadays, materials and process engineering, especially digital-based techniques, are becoming more and more important for esthetic dentistry. Digital communication is also increasing, which is accompanied by a change from a personal contact to a more technocratic and less emotional and empathic communication. Sometimes our personal experiences and perceptions, based on dental, empirical knowledge, collide with this development. It also happens very often, that the patients - with their perceptions, concerns and not least their esthetic preferences - feel neglected by the treatment team...

AIMS AND OBJECTIVES: The aim of this study was to assess the efficacy of 18% hydrochloric acid and 37% phosphoric acid by an in vivo comparison. METHODS: Sixty fluorotic permanent maxillary central incisors from 30 patients were divided into 3 categories. The teeth received 5 seconds (mild fluorosis), 20 seconds (moderate fluorosis) and 30 seconds (severe fluorosis) application of 18% hydrochloric acid on 11 and 37% phosphoric acid on 21. Standardized intraoral photographies were taken immediately before, after, and one month after treatment...

This study aimed to evaluate the perception of lip position preferences in a Saudi population and compare it to the perception of other populations. Master pictures of a male and female Saudi model were prepared with the upper lip 3 mm from Ricketts' E-line and the lower lip 1 mm behind. The lip position was then altered using computer imaging to create a range of pictures from the upper lip 15 mm behind the E-line to the upper lip 6 mm beyond the E-line. One hundred and fifty-six individuals (60 male, 96 female) were asked to rate the pictures in terms of acceptability and also which picture they liked best...

PURPOSE: The aim of this paper is to describe a protocol for a one-stage technique called Immediate Dentoalveolar Restoration (IDR), which uses autogenous bone grafts to restore peri-implant bone defects, presenting the results of mid-term follow-up. SUMMARY: The patient presented a left central incisor that was compromised and with a total loss of buccal bone wall. The proposed treatment followed a protocol of immediate implantation, with a flapless surgery, using corticocancellous bone graft harvested from the maxillary tuberosity to restore the bone defect in question...

The evolution of restorative dental materials has led to the development of more direct or indirect conservative techniques to solve both functional and esthetic problems in anterior and posterior teeth. Several authors have concluded that indirect restorations are the technique of choice in complex cases where shape and colour are difficult to achieve and function has to be restored. Even though there is no clinical evidence of the appropriateness of indirect composites in these treatments, the latest generation of composites used indirectly in the anterior teeth exhibits some interesting characteristics: it supports mechanical stress adequately, has an excellent esthetic result and can be repaired intraorally...

Specialist literature shows that the repeated disconnection of the transmucosal components can generate tissue recession due to the alteration of the delicate environment created between the abutment and surrounding soft tissue. This article will analyze two different techniques of creating the final abutment in the pre-surgery phase, evaluating 2 failing central incisors considered suitable for the immediate tooth replacement technique.

BACKGROUND: The treatment of gingival recessions is one of the important branches of periodontics related to esthetics. However, no surgical technique has been reported for the treatment of a particular type of gingival recession called Stillman's cleft. METHODS: The technique proposed is a laterally moved, coronally advanced flap. After local anesthesia, two parallel incisions, one along the cleft and the second parallel to the first one, have been placed beyond the mucogingival junction, allowing a rotating partial-thickness flap to cover the recession...

In a historical pendulum of porcelain veneer preparation concepts, an oversimplified version of the so-called "no prep" approaches has resurfaced. A case from the USC student clinics is presented, which could be easily considered by many as a "no prep" veneer case. Moderate tooth preparations guided by natural morphology were used instead with a great benefit on the final outcome. While it is widely accepted that minimally invasive restorative approaches should be favored, a certain controversy exists regarding strictly noninvasive approaches...

A full-mouth adhesive rehabilitation in case of severe dental erosion may present a challenge for both the clinician and the laboratory technician, not only for the multiple teeth to be restored, but also for their time schedule, difficult to be included in a busy agenda of a private practice. Thanks to the simplicity of the 3-step technique, full-mouth rehabilitations become easier to handle. In this article the treatment of a very compromised case of dental erosion (ACE class V) is illustrated, implementing only adhesive techniques...
