Introduction Immediate implant placement is a well-recognized and successful treatment option following tooth removal.1 Although the success rates for both immediate and delayed implant techniques are comparable, the literature reports that one can expect there to be recession of the buccal / facial gingiva of at least 1 mm following immediate implant placement, with the recession to possibly w...

Background: Tooth avulsion is described as a displacement of the tooth from its socket. Replantation on an permanent dentition condition that needs immediate treatment. avulsed can be done in span less than 12 hr. Avulsion may occur due to trauma. Factors determine healing after replantation are media storage, periodontal tissue damage, extra-alveolar period and intact alveolar The main goal ma...

The purpose of this study was to investigate the osteopontin mRNA expression in the alveolar bone incident to the physiologic and experimental tooth movement. The upper jaws of female rats (7 weeks old) which were submitted to experimental molar tooth movement and control specimens were decalcified and sliced into paraffin sections. Osteopontin mRNA expression and tartrate-resistant acid phosph...

In dentistry, elevator instruments are used to luxate teeth, and this technique imparts forces to tooth particles that sever the periodontal ligament around tooth roots inside the socket and expand alveolar bone around tooth particles. These effects can result in extraction of the tooth particles or facilitate systematic forceps extraction of the tooth particles. This article presents basic ora...

Dry socket is a particularly unpleasant sequel complicating the extraction o f teeth. Many authors have studied the mul­ tiple factors incriminated in the pathogenesis o f this condi­ tion hut no study lues to date been conducted in the outpa­ tient clinics of the Oral and Dental Teaching Hospital at the University o f the Witwatersrand, Johannesburg. Following a pilot study o f 100 individuals...

UNLABELLED During healing following tooth extraction, inflammation and the immune response within the extraction socket are related to bone resorption. OBJECTIVE We sought to identify how the alloplastic material used for socket preservation affects the immune responses and osteoclastic activity within extraction sockets. MATERIAL AND METHODS Using a porcine model, we extracted teeth and gr...

BACKGROUND Previous studies showed that octacalcium (OCP) collagen composite (OCP/Col) can be used to repair human jaw bone defects without any associated abnormalities. The present study investigated whether OCP/Col could be applied to dental implant treatment using a dog tooth extraction socket model. METHODS The premolars of dogs were extracted; each extraction socket was extended, and tit...

The objective of the present experiment was to evaluate the effect on hard tissue modeling and remodeling of the placement of a xenograft in fresh extraction sockets in dogs. Five mongrel dogs were used. Two mandibular premolars (4P4) were hemisected in each dog, and the distal roots were carefully removed. In one socket, a graft consisting of Bio-Oss Collagen (Geistlich) was placed, whereas th...

Alveolar osteitis is the most common post operative sequel to tooth extraction. It occurs despite the most exacting operative technique, aseptic procedure and regardless of the ability of surgeons. Various packing materials are available for topical treatment of alveolar osteitis. Purpose: The present study was conducted to evaluate and compare the effectiveness of Zinc Oxide Eugenol dressing, ...

The effects of hydroxyapatite (HA)-coating onto collagen carriers for application of recombinant human bone morphogenetic protein 2 (rhBMP-2) on cell differentiation in vitro, and on in vivo healing patterns after sinus-augmentation and alveolar socket-grafting were evaluated. In vitro induction of osteogenic/adipogenic differentiation was compared between the culture media with rhBMP-2 solutio...
