Histomorphometric Evaluation of Bone Formation in Peri-Implant Defects Treated With Different Regeneration Techniques: An Experimental Study in a Rabbit Model.

Purpose: The aim of this study was to investigate the healing of artificially created peri-implant circumferential bone defects using three bone-regeneration techniques.

Materials And Methods: Rabbit tibias (24 rabbits), in which bone defects (9-mm diameter, 4-mm depth) were created and implant beds (3-mm diameter, 6-mm depth) were prepared in the middle of the created defects, were used as the experimental model. Dental implants (3.

The influence of rifamycin decontamination on incorporation of autologous onlay bone grafts in rats: A histometric and immunohistochemical evaluation.

Objective: Although it has been shown that rifamycin is an effective agent for bone graft decontamination, no information exists on the effects of rifamycin decontamination on bone graft incorporation. The aim of this study was to evaluate the influence of rifamycin decontamination on the incorporation of autologous onlay bone grafts quantitatively.

Design: In 30 rats, a standardized 5.

Is it possible to anesthetize palatal tissues with buccal 4% articaine injection?

Purpose: The aim of this study was to evaluate the presence of probable diffused local anesthetic solution at and anesthesia of palatal tissues after buccal injection of 4% articaine hydrochloride (HCl) with 1:100,000 epinephrine or 1:200,000 epinephrine at the premolar and molar region.

Materials And Methods: Thirty volunteers received maxillary buccal injections of 4% articaine HCl with 1:100,000 epinephrine or 1:200,000 epinephrine bilaterally to the first premolar or first molar. Magnetic resonance images were obtained before and 5 minutes after local anesthetic injections, and a visual evaluation was done to determine the presence of local anesthetic solution at palatal tissues.

Effects of simvastatin on mandibular distraction osteogenesis.

Purpose: The aim of this study was to evaluate the effects of local and systemic simvastatin application on distraction osteogenesis.

Materials And Methods: Eighteen New Zealand white rabbits underwent unilateral mandibular distraction osteogenesis. After 7 days of neutral fixation, 0.

Effect of local simvastatin application on mandibular defects.

Osteoinductive characteristics of bone grafts are important for enhancing osseous healing at grafted defect sites. The cholesterol-lowering drug simvastatin has been shown to stimulate bone formation by increasing the gene expression of bone morphogenetic protein-2 and vascular endothelial growth factor. The purpose of this study was to determine the effect of local simvastatin application on bone defect healing and compare the amount of new bone produced by simvastatin gelatin sponge graft with that produced by a gelatin sponge graft and with natural healing.

Infection-related inferior alveolar and mental nerve paresthesia: case reports.

Nerve injury can be related to mechanical, chemical, and thermal factors. Infection-related paresthesia is usually related to mechanical pressure and ischemia associated with the inflammatory process. Another cause of paresthesia could be the toxic metabolic products of bacteria or inflammatory products released following tissue damage.

Utilisation of personal protective equipment in dental practice.

Objective: To investigate personal protective equipment such as gloves, mask and protective eye wear used in dental practice in Turkey.

Design: An e-mail based self-report questionnaire was sent to dentists during 2002.

Participants: Dentists in Turkey.

An unusual buccal adenoma with extensive squamous metaplasia and cyst formation.

Salivary gland tumors are the second most common neoplasm of the mouth following squamous cell carcinoma, and account for a significant proportion of oral tumors. We report a case of an unusual adenoma that presented as a solitary intraoral buccal mass in a 28-year-old male patient. The tumor was intrepreted as an unusual pleomorphic adenoma because of the absence of connective tissue changes and presence of metaplastic epithelial change which is an occasional finding of such tumors.

Osteoblastoma of the mandible with root resorption: a case report.

This article reviews the clinical behavior, histologic features, differential diagnosis, and treatment of a benign osteoblastoma. Benign osteoblastoma is a rare tumor constituting 1% of all primary bone tumors. Only 15% of osteoblastomas occur in the skull and jaw bones.

Pulpal blood flow: effects of corticotomy and midline osteotomy in surgically assisted rapid palatal expansion.

Introduction/purpose: Surgically assisted rapid palatal expansion is used for the management of transverse maxillary deficiency in the early permanent dentition. The success depends on the maintenance of an adequate blood supply to the mobilized segments. The aim of this study was to assess the effects of corticotomy and midline osteotomy on the tooth pulpal blood flow.
