OBJECTIVE: The use of allogeneic bone grafts for alveolar ridge reconstruction has become an often-discussed alternative to augmentation procedures using autografts. Nevertheless, there still is a lack of literature concerning long-time experiences of allografts for alveolar ridge reconstruction. Especially the results of the use of allogeneic bone blocks for mandible reconstructions need to be further investigated. CLINICAL CONSIDERATIONS: In this case report, we present the use of customized allogenic bone blocks in Guided Bone Regeneration (GBR) procedures for severely deficient mandibulary bones, the implantation after a healing period of 5 month and the 24-month follow-up data...

OBJECTIVE: To test the effects of different adhesive protocols and silane application on the adhesive durability to a Lithium Disilicate reinforced glass ceramic. METHODS: Forty disks of 13 mm diameter (E.max Press) were used. After etching with 9.5% HF for 20 seconds, disks were randomly assigned into 4 groups according to the adhesive/silane protocol: silane application only (SIL); silane application followed by adhesive (SILXP-XP Bond); silane-containing adhesive (SBU-ScotchBond Universal); silane application followed by silane-containing adhesive (SILSBU)...

OBJECTIVE: This study evaluated the effects of adhesive type used as modeling liquid on the stability of the color and opacity of composites submitted to thermal cycling in staining solutions followed by a bleaching procedure. METHODS: Thirty cylinder-shaped composite specimens (10 mm diameter × 1.5 mm thickness) were built using or not using (control) an adhesive (Adper Universal or Scotchbond Multipurpose) as the modeling liquid. After polishing procedures, the color and opacity were measured, and the specimens were submitted to 200 thermal cycles with 10 s of dwell time in baths of grape juice at 5°C, water at 37°C, and coffee at 55°C...

PURPOSE: The aim of this systematic review was to evaluate how etching modes affect the nanoleakage of universal adhesive from in vitro studies. MATERIALS AND METHODS: PubMed/MEDLINE, Web of Science, Scopus and Science Direct electronic databases were searched for in vitro studies that evaluated the nanoleakage of universal adhesives. A total of 511 (after duplicate removal) potentially relevant records were identified in the literature search. The titles and abstracts of the retrieved studies were screened by two independent researchers according to the main concept...

OBJECTIVES: Aim of this clinical trial was to investigate the effect of a calcium phosphate based desensitizer paste applied prior to in-office tooth whitening on bleaching sensitivity (BS). METHODS: This crossover study was designed as randomized double-blinded, placebo-controlled trial. The desensitizer paste Teethmate AP (TAP) contains tetracalcium phosphate and dicalcium phosphate anhydrous in glycerol and polyethylene glycol, whereas placebo (PLA) is a calcium phosphate free analog...

OBJECTIVE: To design colorimetric and spectral models of gingival shade guides that adequately represent the color of human gingiva. MATERIALS AND METHODS: A previously compiled database on the spectral reflectance of healthy keratinized gingiva was used for optimization. Coverage Error (CE) and Maximal Error (ME) were optimized using CIELAB and CIEDE2000 color difference formulas. A two-phase process included an FCM algorithm and a nonlinear optimization. A t test was used to compare the performance of the different numbers of clusters/tabs in gingival shade guide models (α = ...

OBJECTIVE: Clinicians have been slow to adopt digital impression technologies due possibly to perceived technique sensitivities involved in data acquisition. This research has two aims: determine whether scan pattern and sequence affects the accuracy of the three-dimensional (3D) model created from this digital impression and to compare the 5 imaging systems with regards to their scanning accuracy for sextant impressions. MATERIALS AND METHODS: Six digital intraoral impression systems were used to scan a typodont sextant with optical properties similar to natural teeth...

OBJECTIVE: To determine 50:50% perceptibility threshold (PT) and 50:50% acceptability threshold (AT) for computer-simulated samples of human gingiva using CIEDE2000 and CIELAB color difference formulas. MATERIALS AND METHODS: Each of the 60 pairs of simulated human gingiva was displayed on a calibrated monitor, together with three pairs of upper central incisors of different lightness. The color of gingiva left and right from the midline was compared. A total of 30 observers (15 dentists, 15 laypersons) participated in the study...

OBJECTIVES: Phytate is an organic, cyclic polyphosphate analogous to linear condensed polyphosphates used as stain removal agents. This study investigated stain removal efficacy of an experimental sodium phytate-containing dentifrice compared to a reference dentifrice. METHODS: An experimental, moderate abrasivity (relative dentine abrasivity [RDA] ∼130) antisensitivity fluoride dentifrice containing sodium phytate (0.85% w/w as the hexasodium salt) (n = 111) was compared to a reference, marketed, low-abrasivity (RDA ∼ 43), anti-sensitivity fluoride dentifrice (n = 113), both containing 1150 ppm fluoride as sodium fluoride...

OBJECTIVE: This study aimed to evaluate the effect of 35% hydrogen peroxide at different pH values and the degree of tooth staining on whitening efficacy and enamel microhardness. MATERIALS AND METHODS: 90 enamel-dentin specimens were obtained from bovine incisors. They were randomly divided into 2 groups (n = 45), 1 group was immersed in a staining broth for 14 days, and another group was not stained and kept in distilled water at 37°C. Twenty-four hours after the staining procedure, each group was distributed into 3 subgroups that were whitened by 35% hydrogen peroxide with different pH values (5, 7, and 8...

OBJECTIVE: Orofacial esthetics raises psychosocial issues. The purpose was to create and validate new short instrument for psychosocial impacts of altered smile esthetics. MATERIALS AND METHODS: A team of an orthodontist, two prosthodontists, psychologist, and a dental student generated items that could draw up specific hypothetical psychosocial dimensions (69 items initially, 39 in final analysis). The sample consisted of 261 Caucasian subjects attending local high schools and university (26% male) aged 14 to 28 years that have self-administrated the designed questionnaire...
