Assessing Enamel Wear of Monolithic Ceramics With Micro-CT and Intra-oral Scanner.

Objective: This in vitro study aimed to investigate enamel wear against 3 monolithic ceramics using 2 methods of measurement.

Methods: Three groups of standard flat monolithic ceramic specimens including zirconia-reinforced lithium silicate glass (Vita Suprinity, VITA Zahnfabrik), yttria-stabilised tetragonal zirconia (Lava Esthetic Zirconia), and lithium disilicate glass (IPS e.max Press, Ivoclar Vivadent) were prepared, with human enamel used as the control group.

'Evaluation of the introduction of a dental virtual simulator on the performance of undergraduate dental students in the pre-clinical operative dentistry course'.

Introduction: Virtual reality-based platforms are becoming increasingly popular in education. The aim of this study was to evaluate the performance of undergraduate dental students with the introduction of the Moog Simodont dental trainer (VR) within the pre-clinical curriculum in the direct restoration module of the operative dentistry course using manual and digital methods.

Methods: Thirty-two randomly selected year 2 undergraduate students were divided into two groups: group 1, exposed to the Moog Simodont dental trainer (VR) and group 2, no exposure to VR.

Human serum promotes Candida albicans biofilm growth and virulence gene expression on silicone biomaterial.

Objectives: Systemic candidal infections are a common problem in hospitalized patients due to central venous catheters fabricated using silicone biomaterial (SB). We therefore evaluated the effect of human serum on C. albicans biofilm morphology, growth, and the expression of virulence-related genes on SB in vitro.

Differences in dentofacial characteristics between southern versus northern Chinese adolescents.

Aim: To compare the dentofacial characteristics of southern and northern Chinese adolescents.

Methods: A southern Chinese sample comprised 70 males (Mean age 12.4 +/- 0.

Assessment of maxillary position. Implant vs cephalometric methods.

Objective: To compare changes in maxillary position assessed from a maxillary implant and three cephalometric methods based on linear measurements.

Methods: Series of tracings of the maxilla obtained around puberty from an implant study were analyzed. The displacement of the implant was used to determine the direction and amount of "actual" maxillary growth.
