Purpose: The purpose of this study was to investigate the surface roughness (Ra) of different esthetic restorative materials following simulated toothbrushing using different whitening dentifrices.
Materials And Methods: Cylinders of Esthet-X (Dentsply Caulk, Milford, DE, USA), Durafil VS (Heraeus Kulzer, Wehrheim, Germany), and Vitremer (3M ESPE, St. Paul, MN, USA) were made using molds (4 mm in diameter for 2 mm in height). The superficial roughness was evaluated using a profilometer (Ra) with a cutoff length of 0.25 mm and a speed of 0.1 mm/s. The specimens (N=13) were submitted to 7,500 brushing cycles using five different toothpastes: (1) Crest Regular (control; Procter & Gamble): silica abrasive (C); (2) Crest Extra Whitening (Procter & Gamble, Cincinnati, OH, USA): bicarbonate+calcium pyrophosphate (CE); (3) Dental Care A & H (Arm & Hammer, Camilla, GA, USA): bicarbonate (DC); (4) Rembrandt Plus Whitening (Oral B Laboratories, Belmont, CA, USA): carbamide peroxide+alumina/silica (RP); and (5) experimental: hydrogen peroxide+calcium carbonate (EX).
Results: The data were analyzed by analysis of variance and Tukey's test (alpha=.05) for each restorative material, and the results [difference between final and initial roughness: Ra(F)-Ra(I) in microm] were as follows: Esthet-X: EX=0.15+0.07a; RP=0.29+0.16a; CE=0.96+0.33b; C=1.03+0.29b; DC=1.48+0.37b; Durafil VS: RP=0.09+0.07a; EX=0.55+0.23abc; C=0.96+0.26bc; CE=1.03+0.33cd; DC=1.09+0.37d; and Vitremer: EX=0.10+0.08a; RP=0.26+0.19a; CE=0.94+0.27b; DC=1.13+0.46bc; C=1.50+0.32c (different letters mean differences among groups).
Conclusion: It was verified that the dentifrices containing carbamide or hydrogen peroxide along with alumina+silica and calcium carbonate, respectively (groups 4 and 5), produced minor changes in Ra when compared with the control group and with those dentifrices containing bicarbonate (groups 2 and 3). CLINICAL significance The results of this study indicate that whitening dentifrices evaluated containing silica or calcium carbonate were less abrasive when used on the resin-based esthetic restorative materials than those that contain sodium bicarbonate.

Objectives: This double-blind randomised crossover trial aimed to compare the aesthetic outcomes of CAD-CAM manufactured provisional restorations created using cone beam computed tomography (CBCT) and intraoral scanners (IOS) acquisition methods.
Methods: Twelve participants (mean-age: 38 ± 5 years) requiring full mouth rehabilitation were included in this crossover trial. Two sets of identical CAD-CAM provisional restorations, differing only in the method of data acquisition (A: CBCT, B: IOS), were fabricated.

Background: Facial palsy (FP) is a widespread condition affecting over 3 million people annually, with a complex etiology requiring tailored, multidisciplinary management. Despite advancements, there remains a lack of reliable, automated tools for objective pre- and postoperative assessment, limiting progress in treatment optimization. This study introduces the AI Research Metrics Model (CAARISMA ® ARMM) to evaluate FP severity and outcomes following microsurgical gracilis muscle transfer.

Cleft lip and palate anomalies constitute both aesthetic and functional impairments for affected individuals. While an individual with an unrepaired cleft palate may adjust somewhat to the associated feeding challenges as he or she gets older, the consequent speech impairment is amenable primarily to surgery. It is pertinent to assess how well speech function is restored in individuals with cleft after surgical repairs.

To explore the application of modified Von Langenbeck cleft palate repair with tension-free mucoperiosteal flap near the nasal cavity and without relaxation incision, and the cleft palate defect was repaired by covering both sides of the edge of the in situ mucoperiosteal flap. This treatment method provides a good aesthetic restoration effect. Modified Von Langenbeck cleft palate repair with mucoperiosteal flap near the nasal cavity without tension and relaxation incision was used to repair the cleft palate.

Full-arch zirconia restorations on implants have gained popularity due to zirconia's strength and aesthetics, yet they are still associated with challenges like structural fractures, peri-implant complications, and design misfits. Advances in CAD/CAM and digital workflows offer potential improvements, but a technique that consistently addresses these issues in fixed, full-arch, implant-supported prostheses is needed. This novel technique integrates a facially and prosthetically driven treatment approach, which is divided into three phases: data acquisition, restoration design, and manufacturing/delivery.
