Application of organoselenium in inhibiting Candida albicans biofilm adhesion on 3D printed denture base material.

Purpose: Denture Stomatitis, a chronic mucosal inflammation associated with Candida albicans, is common among denture wearers. Several health conditions have been linked to chronic Candida infections. The complex, multifactorial nature of denture stomatitis requires the continuous pursuit of effective long-term solutions.

Bur Choice When Removing Zirconia Restorations.

Purpose: Removal of zirconia restorations can be challenging and time consuming, requiring dental burs with optimal cutting efficiency to minimize iatrogenic complications. Yet, there are very few burs marketed for this purpose and little evidence of their comparative benefit. This study evaluated one specialized bur and compared its cutting efficiency with three general-purpose burs (one single use and two multiple uses).

Critical Thinking in Dental Students and Experienced Practitioners Assessed by the Health Sciences Reasoning Test.

To date, there has been a lack of published studies examining the validity of the Health Sciences Reasoning Test (HSRT) to assess critical thinking among dental students. The aim of this study was to examine the construct validity of the HSRT using a novice-expert model consisting of first-year dental students as novices and experienced general dentists as experts. Novice cohort subjects were recruited from all 105 students in the first-year dental school class at the University of Texas Health Science Center at San Antonio during a regularly scheduled course in August 2015.

Fracture Resistance of Pressed and Milled Lithium Disilicate Anterior Complete Coverage Restorations Following Endodontic Access Preparation.

Purpose: This in vitro study evaluated the fracture resistance and clinical prognosis of anterior lithium disilicate crowns (e.max Press and e.max CAD), following endodontic access and repair.

Management of Challenging Esthetic Anterior Cases with Limited Restorative Space: A Clinical Report.

With careful restorative planning and surgical placement, dental implants can be used to support and retain a wide range of esthetic prostheses. When implant planning or surgical executions are less than ideal, however, the resulting restorative space can be a significant obstacle to successful treatment. The aim of this article is to describe the use of a customized anterior bar to support a partial overdenture prosthesis for a youthful patient with a high smile line and a limited restorative space of 6 mm.

Marginal discrepancy of noble metal-ceramic fixed dental prosthesis frameworks fabricated by conventional and digital technologies.

Statement Of Problem: Studies evaluating the marginal adaptation of available computer-aided design and computer-aided manufacturing (CAD-CAM) noble alloys for metal-ceramic prostheses are lacking.

Purpose: The purpose of this in vitro study was to evaluate the vertical marginal adaptation of cast, milled, and direct metal laser sintered (DMLS) noble metal-ceramic 3-unit fixed partial denture (FDP) frameworks before and after fit adjustments.

Material And Methods: Two typodont teeth were prepared for metal-ceramic FDP abutments.

Effect of Split-File Digital Workflow on Crown Margin Adaptation.

Purpose: Computer-aided design/computer-aided manufacturing (CAD/CAM) is becoming increasingly integrated into dental practice workflow at a pace that exceeds scientific validation. The aim of this study is to evaluate a complete digital split-file protocol relative to segmental digital and analog techniques for restoring a single maxillary anterior edentulous space with custom abutment and crown.

Materials And Methods: Four treatment workflows were assessed: complete digital (CD), segmental digital (SD), milled wax (AM), and heat pressed and hand waxed (AH) and heat pressed.

Enhancing Fracture and Wear Resistance of Dentures/Overdentures Utilizing Digital Technology: A Case Series Report.

Since it was first introduced into the dental world, computer-aided design/computer-aided manufacturing (CAD/CAM) technology has improved dramatically in regards to both data acquisition and fabrication abilities. CAD/CAM is capable of providing well-fitting intra- and extraoral prostheses when sound guidelines are followed. As CAD/CAM technology encompasses both surgical and prosthetic dental applications as well as fixed and removable aspects, it could improve the average quality of dental prostheses compared with the results obtained by conventional manufacturing methods.

Marginal Gap of Milled versus Cast Gold Restorations.

Purpose: This in vitro study evaluated and compared the vertical marginal gap of cast and milled full coverage gold copings using two margin designs (chamfer and chamfer bevel) before and after fitting adjustments.

Materials And Methods: Ten impressions were made of two metal master dies (one chamfer margin, one chamfer-bevel margin) and poured twice in Type IV stone. The 20 subsequent casts with 40 dies were split into four groups (n = 10); cast gold bevel, cast gold chamfer, milled gold bevel, and milled gold chamfer groups.

Precision of fit between implant impression coping and implant replica pairs for three implant systems.

Statement Of Problem: The fabrication of an accurately fitting implant-supported fixed prosthesis requires multiple steps, the first of which is assembling the impression coping on the implant. An imprecise fit of the impression coping on the implant will cause errors that will be magnified in subsequent steps of prosthesis fabrication.

Purpose: The purpose of this study was to characterize the 3-dimensional (3D) precision of fit between impression coping and implant replica pairs for 3 implant systems.

Rubrics 101: a primer for rubric development in dental education.

Identifying and implementing effective methods for assessing dental student performance are ongoing challenges for dental educators. Questions related to grading and assessment are common among faculty and students alike. Faculty members who are well-trained clinicians or scientists often have little formal training in education.

The chamfer finish line: preclinical student performance using different bur designs.

The primary purposes of this investigation were to evaluate sophomore dental student performance in the production of a chamfer finish line using two diamond bur types-a round-ended bur and a torpedo-shaped bur-and to gain student feedback about their preferences for bur type. Fifty students took part in the study, each of whom prepared the buccal surfaces of two mandibular molar typodont teeth, producing chamfer finish lines. Students prepared both teeth in the same laboratory session and were randomly assigned to two groups that were required to prepare the first of the two molars with a specific bur type.

Functional impressions for complete denture fabrication. A modified jump technique.

Tissue conditioners are used with great success in dentistry as functional impression materials for rebasing removable prostheses. In the rebase procedure, a functional impression is made in an existing denture to create a master cast. The orientation of the occlusal surface to the underlying tissue surface is captured with a reline jig or denture flask and transferred to the new denture base in what is called a "jump" in laboratory jargon.
