The purpose of the present study was to evaluate the efficacy of a single dose of botulinum toxin (BTX) at the Yonsei point for the treatment of gummy smile (GS). A total number of 45 female patients were enrolled in the study at a private clinic over a period of 24 months. Three units of onabotulinumtoxinA (BTX-A) per site (90 hemifacies) were initially injected at the Yonsei point. The patients were then assessed at 2, 12, 24, and 36 weeks postinjection. The data were evaluated using mean standard deviation, analysis of variance (ANOVA), and Tukey's post hoc test...

PURPOSE: This study evaluated the shear bond strength (SBS) of resin cement to dentin after applying two adhesive (A) systems with a combination of four different immediate dentin sealing (IDS) strategies, and two surface conditioning (SC) methods. MATERIAL AND METHODS: Human third molars (n = 140) were collected and randomly split (n = 70 each) between the two A systems (Clearfil SE Bond; Kuraray [AC] and Optibond FL; Kerr [AO]). The A groups were further divided into four IDS strategies (2 x one adhesive layer (IDS-1L); 2 x two adhesive layers (IDS-2L); 2 x one adhesive layer and one flowable layer (IDS-F); 2 x no adhesive layer (delayed dentin sealing [DDS])...

A healthy and adequate band of keratinized periimplant mucosa is key to long-term biologic and esthetic success. Yet in about one-third of implant patients, its formation requires connective tissue graft procedures. Such procedures may be considered impractical for patients who need retreatment of failures, those who are not willing to go through multiple surgical steps, or those receiving multiple implants that would thus involve multiple connective tissue grafts. This article introduces the buccal pedicle fl ap technique, a new surgical approach for boosting the soft tissue around dental implants without connective tissue grafting...

PURPOSE: To evaluate and compare light propagation in dental tissues and dental composite restorations using a double-layer build-up technique. MATERIALS AND METHODS: Natural teeth slabs and dental restoration buildups with A2D and B1E-colored nanofilled, supra-nanofilled, and microhybrid composites were randomized and equally distributed into four experimental groups (n = 10). Using a spectrophotometer, the samples were irradiated by three wavelengths of lasers: red, green, and blue...

Following the guidelines of the 'index technique' that were published in this journal in 2015, this article presents the 'digital index technique,' an updated no-prep restorative approach to the management of worn dentition. Patients with minimal, moderate, and severe hard tissue wear can be treated based on the application of minimally invasive or noninvasive adhesive composite restorations on posterior and anterior worn dentition. The technique allows for a purely additive treatment without sacrificing healthy hard tooth tissue...

PURPOSE: To determine the most and least attractive smiles from a Brazilian sample and to correlate the anatomical characteristics identified in these smiles. MATERIALS AND METHODS: Orthodontists, dentists, and laypeople assessed the photographs of 86 students (66 women and 20 men), aged between 19 and 30 years, using a visual analog scale (VAS). An evaluator blinded to the results measured the esthetic composition of the eight photographs with the highest and the eight with the lowest ratings for women, and the two with the highest and the two with the lowest ratings for men...

Tooth wear is generally a physiological process; however, it can also be a pathological condition associated with attrition, abrasion, and erosion processes in which the quantity of tooth loss is atypical for the patient's age. Tooth substance loss often causes functional problems, symptoms of discomfort/pain, and esthetic impairments. Patients presenting this condition frequently need restorative treatment, combined with an increase in the vertical dimension of occlusion (VDO). A diagnostic wax-up (DWU) provides assistance in determining a new occlusal plane and VDO, and is a fundamental tool considering the backward planning involved in the execution of a complex rehabilitation...

The mock-up is a diagnostic technique that allows for the intraoral try-in of a prosthetic rehabilitation. Mock-ups facilitate significant improvement in communication with patients by showing them the potential final outcome of the treatment. They also allow for a quick and easy comparison of the pre- and postoperative situations, and permit the clinician to check the functional aspects of the therapy. The purpose of this article is to describe the use of the full-mouth mock-up technique for testing all the functional and esthetic parameters of extensive rehabilitations associated with a VDO increase with completely additive wax-ups...

The buccal bone wall is the part of the socket of an anterior tooth that is most susceptible to resorption. Immediate implants offer advantages in terms of time, comfort, and esthetics, especially regarding the maintenance of the papillae architecture. However, the loss of the buccal bone wall is often a limitation for such a therapy. This case report describes a clinical procedure designed to reconstruct the buccal bone wall to restore an anterior tooth where this wall was absent. The approach involved a flapless immediate implant based on the principles of guided bone regeneration (GBR), and consisted of the preparation of a large, flapless recipient bed ad modum envelope, immediate implant placement, deposition of xenograft surrounding the implant surface, and coverage with a collagen membrane...

This article revisits the concept of biologic width, in particular its clinical consequences for treatment options and decisions in light of modern dentistry approaches such as biomimetics and minimally invasive procedures. In the past, due to the need to respect biologic width, clinicians were used to removing periodontal tissue around deep cavities, bone, and gum so that the limits of restorations were placed far away from the epithelium and connective attachments, in order to prevent tissue loss, root exposure, opening of the proximal area (leading to black holes), and poor esthetics...
