OBJECTIVE The objective of this study was to investigate whether regions of cartilage in the tibiofemoral joint where cartilage-to-cartilage contact occurred was thicker than other regions. DESIGN In vivo human subjects. BACKGROUND The thickness of the cartilage in the knee has been investigated in various studies. However, the factors that influence(More)
OBJECTIVES The purpose of this study was to investigate the difference in optical appearance of the soft tissues labial to dental implants and to analyze the effects of titanium implant neck colors transmitted through the marginal mucosa. MATERIALS AND METHODS Fourteen patients with 15 Straumann single implant replacements in the maxillary anterior region(More)
STATEMENT OF PROBLEM Matching a natural maxillary central incisor to a metal ceramic crown is one of the most difficult challenges in clinical dentistry due to the limitations of dental shade guides and the subjectivity of perceptual evaluation. PURPOSE The purpose of this study was to assess the clinical effectiveness of a spectrophotometric(More)
This study was aimed to compare robotic-assisted implantation of a total knee arthroplasty with conventional manual implantation. We controlled, randomized, and reviewed 72 patients for total knee arthroplasty assigned to undergo either conventional manual implantation (excluding navigation-assisted implantation cases) of a Zimmer LPS prosthesis (Zimmer,(More)
We carried out an anthropometric analysis using three dimensional computer tomographic measurements of the cut surface of the proximal tibia in 200 knees that were obtained from 50 male and 50 female Korean cadavers. We measured the mediolateral (ML), middle anteroposterior (AP), medial and lateral anteroposterior dimensions and the aspect ratio (ML/AP) of(More)
OBJECTIVE We aimed to understand the involvement of imprinted genes in the pathogenesis of gestational trophoblastic diseases (GTD) such as hydatidiform mole (H-mole) and gestational trophoblastic tumors (GTT). METHODS An allelic-typing assay was performed using a PCR-RFLP-based method for identification of heterozygous informative cases. The usage of(More)
PURPOSE The aim of this study was to investigate the ability of a new surface-modified denture resin to reduce adhesion of Candida albicans to the denture surface. This material has a negative charge incorporated by copolymerization of methacrylic acid to methyl methacrylate. An in vitro system was designed to assess the adhesion of C. albicans to(More)
The purpose of this study was to evaluate the association between student performance and tutor expertise and experience in the Restorative Treatment course in a problem-based learning (PBL) dental curriculum. This retrospective study evaluated a cohort of 206 third-year dental students at Harvard School of Dental Medicine who were enrolled in the(More)
Unicompartmental knee arthroplasty (UKA) has regained popularity in recent years. However, limited data exist on how UKA affects knee biomechanics. The role of the anterior cruciate ligament (ACL) after fixed bearing UKA remains controversial. In this study, a robotic testing system was used to apply a quadriceps/hamstrings load to cadaveric knee specimens(More)
BACKGROUND Quantifying the in vivo cartilage contact mechanics of the knee may improve our understanding of the mechanisms of joint degeneration and may therefore improve the surgical repair of the joint after injury. OBJECTIVE To measure tibiofemoral articular cartilage contact kinematics during in vivo knee flexion. STUDY DESIGN Descriptive laboratory(More)
