Periodontal wound healing following reciprocal autologous root transplantation in class III furcation defects.

Purpose: Furcation involvement in the molars is difficult to treat, and has been recognized as a risk factor for tooth loss. Although periodontal regenerative therapies, including guided tissue regeneration and various types of bone grafts, have been applied to furcation defects, the effects of these treatments are limited, especially in large class III furcation defects. The purpose of this pilot study was to investigate the effect of reciprocal autologous root transplantation on periodontal wound healing and regeneration in class III furcation defects in dogs.

Clinical Anatomy of the Frenulum of the Oral Vestibule.

Introduction The frenula of the oral vestibule include the labial and buccal frenula. Abnormal labial and buccal frenula can affect facial esthetics and oral cavity function by retracting the gingival margin, creating a median diastema, and limiting lip movement. Because of the lack of information on these structures, we aimed to clarify their anatomy.

The Association of Periodontopathic Bacteria Levels in Saliva and Tongue Coating with Oral Malodor in Periodontitis Patients.

Purpose: To elucidate the association oral malodor with the levels of periodontopathic bacteria in saliva and tongue coating of periodontitis patients with oral malodor.

Materials And Methods: In 25 periodontitis patients, the organoleptic test (OLT) was performed, the levels of volatile sulfur compounds (VSCs) were measured, tongue coating (TC) score was determined, and periodontal parameters and the proportions of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Treponema denticola, Tannerella forsythia and Prevotella intermedia in the saliva and the tongue coating were evaluated.

Results: The proportions of T.

Effects of enamel matrix derivative and basic fibroblast growth factor with μ-tricalcium phosphate on periodontal regeneration in one-wall intrabony defects: an experimental study in dogs.

This study evaluated the effects of enamel matrix derivative (EMD) and basic fibroblast growth factor (bFGF) with μ-tricalcium phosphate (μ-TCP) on periodontal healing in intrabony defects in dogs. One-wall intrabony defects created in dogs were treated with μ-TCP alone (μ-TCP), EMD with μ-TCP (EMD/μ-TCP), bFGF with μ-TCP (bFGF/μ-TCP), and a combination of each (EMD/bFGF/μ-TCP). The amount of new bone formation was not significant for any group.

Bone formation using β-tricalcium phosphate/carboxymethyl-chitin composite scaffold in rat calvarial defects.

Objective: The aim of the present study was to evaluate the effects of β-tricalcium phosphate/carboxymethyl-chitin material (β-TCP/CM-chitin) on bone formation in rat calvarial defects.

Study Design: Eighteen animals surgically received 2 calvarial defects (5 mm) bilaterally in each parietal bone. β-TCP/CM-chitin was implanted in one side of each defect, and the contralateral side of the defect was left empty as a control.

Effect of bone swaging with calcium phosphate bone cement on periodontal regeneration in dogs.

Objectives: The present study evaluated the effects of bone swaging (BS) with injectable calcium phosphate bone cement (CPC) on periodontal healing in 1-wall intrabony defects in dogs.

Study Design: Surgically created 1-wall intrabony defects were treated with BS, CPC, BS with CPC (BS/CPC), or open-flap debridement (OFD). The animals were humanely killed for histologic evaluation at 8 weeks.

Cellular compatibility of a gamma-irradiated modified siloxane-poly(lactic acid)-calcium carbonate hybrid membrane for guided bone regeneration.

A bi-layered silicon-releasable membrane consisting of a siloxane-poly(lactic acid) (PLA)-vaterite hybrid material (Si-PVH) microfiber mesh and a PLA microfiber mesh has been developed by an electrospinning method for guided bone regeneration (GBR) application. The bi-layered membrane was modified to a three-laminar structure by sandwiching an additional PLA microfiber mesh between the Si-PVH and PLA microfiber meshes (Si-PVH/PLA membrane). In this study, the influence of gamma irradiation, used for sterilization, on biological properties of the Si-PVH/PLA membrane was evaluated with osteoblasts and fibroblasts.

Regenerative effect of basic fibroblast growth factor on periodontal healing in two-wall intrabony defects in dogs.

Aim: The aim of the present study was to evaluate the effect of a basic fibroblast growth factor (bFGF) candidate treatment on periodontal healing in two-wall intrabony defects in dogs.

Materials And Methods: Two-wall intrabony defects (5 x 5 x 5 mm) were created surgically on the distal and mesial sides of bilateral mandibular second and fourth premolars in four Beagle dogs. bFGF, enamel matrix derivative (EMD) and platelet-derived growth factor with beta-tricalcium phosphate (PDGF/beta-TCP) treatments, and sham-surgery (OFD) were rotated among the four defects in each animal, EMD and PDGF/beta-TCP serving as benchmark controls.
