The efficacy of the local application of recombinant human fibroblast growth factor-2 (FGF-2) in periodontal regeneration has been investigated. In this study, a randomized, double-blind, placebo-controlled clinical trial was conducted in 253 adult patients with periodontitis. Modified Widman periodontal surgery was performed, during which 200 µL of the(More)
BACKGROUND AND OBJECTIVE A three-dimensional scaffold may play an important role in periodontal tissue engineering. We prepared bio-safe collagen hydrogel, which exhibits properties similar to those of native extracellular matrix. The aim of this study was to examine the effect of implantation of collagen hydrogel/sponge scaffold on periodontal wound(More)
Vertical root fractures lead to advanced periodontal breakdown with deep periodontal pockets and vertical bone defects. The purpose of this study is to evaluate clinically the periodontal healing of root fracture treatment using adhesive resin cement. In 22 patients, 23 teeth with vertical root fractures were treated with 4-META/MMA-TBB resin cement. Eleven(More)
In eukaryotic cells, degradation of most intracellular proteins is carried out by the ubiquitin-proteasome pathway. Recent investigations suggest that bone metabolism is also regulated by this pathway. The clinical efficacy of bortezomib, a 26S proteasome inhibitor used as an anticancer drug, has been linked to an increase in bone formation. In this study,(More)
BACKGROUND AND OBJECTIVE Recent studies have shown that bone morphogenetic protein-2 (BMP-2) stimulates mineralization and osteoclast differentiation. Osteoclastic resorption by BMP-2 application may play an important role in the regulation of new cementum-like tissue formation on the dentin surfaces. Therefore, this study aimed to examine the effect of(More)
OBJECTIVE Determine whether a six-step behavioral cognitive method is more effective than traditional oral hygiene instruction. METHODS Thirty-eight patients with chronic periodontitis were randomly assigned to two groups. The control group was given traditional oral hygiene instruction for 20 min. The intervention group received counseling by Farquhar's(More)
We investigated the efficacy, safety, and clinical significance of trafermin, a recombinant human fibroblast growth factor (rhFGF)-2, for periodontal regeneration in intrabony defects in Phase III trials. Study A, a multicenter, randomized, double-blind, placebo-controlled study, was conducted at 24 centers. Patients with periodontitis with 4-mm and 3-mm or(More)
OBJECTIVES Periodontal regeneration under application of bone morphogenetic protein (BMP) is compromised by ankylosis. Ankylosis disappearance following application of BMP has been observed in the case of a small defect, which might be beneficial change for periodontal regeneration. However, the histological observation of ankylosis disappearance has not(More)
PURPOSE This study's purpose was to develop a task-specific self-efficacy scale for maternal oral care (SESMO) with reliability and validity. METHODS A draft scale consisting of 36 items was designed and tested on 119 mothers at a dental clinic. Item analysis was performed to improve its accuracy by reducing the number of items. Internal consistency and(More)
This study evaluated apical periodontal healing after root-end sealing using 4-META/MMA-TBB resin (SB), and root-end filling using reinforced zinc oxide eugenol cement (EBA) or mineral trioxide aggregate (MTA) when root canal infection persisted. Apical periodontitis was induced in mandibular premolars of beagles by contaminating the root canals with dental(More)
