BACKGROUND One-stage full-mouth disinfection (FMD), in which full-mouth scaling and root planing (SRP) is performed with adjunctive use of chlorhexidine, was introduced in 1995. There have been several reports on the effectiveness of this treatment protocol. However, FMD was reported to induce pyrexia frequently. We examined the effects of full-mouth SRP in(More)
BACKGROUND Azithromycin is an azalide antibiotic, effective against a wide range of oral bacteria including periodontopathic bacteria. Azithromycin is taken up by phagocytes and is released into inflamed tissue over time. The concentration of azithromycin in inflamed periodontal tissues over time has not been studied. In this study, we determined the(More)
OBJECTIVE We examined the stress-strain and stress-relaxation properties of the periodontal ligament (PDL) in the rat molar at 2, 6, 12, and 24 months of age to elucidate age-related changes in the tooth support function of the PDL. DESIGN From the dissected left and right mandibles in each rat, a pair of transverse sections (ca. 0.45 mm in thickness) of(More)
The purpose of this study was to identify the periodontal regeneration factors of enamel protein extracts that induce cementum and bone regeneration in vivo. Cementum regeneration, one aspect of periodontal ligament regeneration, was examined using a buccal dehiscence model of dogs. Enamel matrix protein fractions were prepared from developing porcine(More)
BACKGROUND AND OBJECTIVE Commercially available enamel proteins, such as Emdogain, are clinically used for periodontal regeneration. However, the real mechanisms behind the bioactivities of enamel proteins is still unclear, as enamel proteins have multicomponents. The purpose of this in vivo study was to identify the cementum regeneration-promoting factor(More)
Periodontitis is a common inflammatory disease causing destruction of periodontal tissues. It is a multifactor disease involving genetic factors and oral environmental factors. To determine genetic risk factors associated with aggressive periodontitis or severe chronic periodontitis, single nucleotide polymorphisms (SNPs) in multiple candidate genes were(More)
BACKGROUND AND OBJECTIVE Enamel sheath protein (ESP) is involved in the construction of the enamel sheath during tooth development. The 17 kDa ESP is a one-step cleavage product processed by proteolysis from the N-terminal side of sheathlin (ameloblastin/amelin), one of the porcine enamel matrix proteins. Enamel sheath protein exhibits periodontal ligament(More)
This study describes the generation of an active hematopoietic marrow within the confines of a biodegradable, macroporous polyester scaffold, seeded with rat osteogenic cells, after subcutaneous implantation in nude mice. A macroporous, poly(DL-lactide-co-glycolide) polymer scaffold, into which resorbable calcium phosphate particles were incorporated, was(More)
We investigated the prevalences and risk factors for peri-implant diseases in Japanese adult dental patients attending a follow-up visit at dental hospitals or clinics as part of their maintenance program. This cross-sectional multicenter study enrolled patients with dental implants who attended regular check-ups as part of a periodontal maintenance program(More)
Three groups of male Wistar rats received daily subcutaneous injections of 10 mg/kg of hydrocortisone (HC group), 300 mg/kg of beta-aminopropionitrile (BAPN group), or saline (control group), for 10 days. The shear stress-strain and stress-relaxation properties of the incisor periodontal ligament were examined in transverse sections from dissected(More)
