Investigation of the Effects of Ozon and Propolis on the Healing of Bone Defects: An Experimental Study.

Background/aim: This study explores the effects of ozone and propolis on the healing of critically sized bone defects at both the histologic and molecular levels, and the locations and concentrations of osteopontin and osteonectin during healing; both proteins play roles during bone healing.

Materials And Methods: This study used 56 adult male Sprague-Dawley rats of an average weight of 350 g, divided into four groups of 14: a control group, a topical ozone group (O), a topical ozone + systemic propolis (O + PO) group, and a systemic propolis group (PO). Seven rats from each group were sacrificed at the end of week 4 and the other seven at the end of week 6.

Investigation of the effects of quercetin and xenograft on the healing of bone defects: An experimental study.

Objective: In this study, it was aimed to histologic and immunohistochemical examined that the effects of quercetin on new bone formation and bone regeneration in critical size rat tibial bone defects.

Material & Methods: In the study, 56 rats were divided into 4 groups with 14 rats in each group. Control (C) (n = 14): A defect was created in the corticocancellous bone in the metaphyseal part of the tibia bones of the rats and no additional procedure was applied until the end of the experimental setup.

Effects of Systemic Propranolol Application on the New Bone Formation in Periimplant Guided Bone Regeneration.

Objectives: The aim of this experimental animal study was to evaluate the effects of systemic propranolol on new bone formation in peri-implant bone defects.

Material And Methods: Implant slots were created 4mm long and 2.5 mm wide.

Effects of local application of the ankaferd blood stopper on osseointegration in three different surface titanium implants.

Objective: Researchs of the effects of ankaferd blood stopper (ABS) on bone healing metabolism have revealed that it affects bone regeneration positively. The exact mechanism by which this positive effect on bone tissue metabolism is not known. The aim of this study is to biomechanic and biochemical analysis of the effects of the local ABS application on osseointegration of 3 different surfaced titanium implants.

Biomechanical and biochemical evaluation of the effect of systemic application of omeprazole on the osseointegration of titanium implants.

Background: This study aimed to investigate the effects of systemic omeprazole treatment on the osseointegration of titanium implants.

Material And Methods: After surgical insertion of titanium implants into the metaphyseal part of rats' both right and left tibial bones, the animals were randomly divided into three equal groups: control (n = 8), omeprazole dosage-1 (n = 8) (OME-1), and omeprazole dosage-2 (n = 8) (OME-2) and totally 48 implants were surgically integrated. The rats in the control group received no treatment during the four-week postoperative experimental period.

Biomechanical Evaluation of Implant Osseointegration After Guided Bone Regeneration With Different Bone Grafts.

The aim of this study was to compare the biomechanical osseointegration of titanium implants after guided bone regeneration (GBR) with a hydroxyapatite graft, deproteinized bovine bone graft, human-derived allograft, and calcium sulfate bone graft. Thirty-two female Sprague Dawley rats were divided into four groups, each containing eight (n = 8) rats: hydroxyapatide (HA), deproteinized bovine bone graft (DPBB), allograft (ALG), and calcium sulfate. Bone defects were created in the tibia of the rats, which were grafted with HA, DPBB, ALG, or CP bone grafts for the purpose of GBR.

Systemic and local zoledronic acid treatment with hydroxyapatite bone graft: A histological and histomorphometric experimental study.

In this study, the aim was to compare the relative efficacy of systemic and local zoledronic acid (ZA) on a hydroxyapatite (HA) bone graft in a rat critical-size calvarial bone defect. In total, 84 female rats were divided into four groups: Empty control (EC) group with no treatment applied; HA group, in which only HA bone graft material was used in the calvarium; and HA plus local ZA (HA+LZA) and HA plus systemic ZA (HA+SZA) groups, in which animals received ZA locally or systemically, respectively, with HA bone graft material in the calvarium. A 5-mm standardised critical-size calvarial bone defect was created with a standard trephine drill and the respective treatment was applied.

Pentoxifylline and electromagnetic field improved bone fracture healing in rats.

Background: The aim of this study was to evaluate the effects of a phosphodiesterase inhibitor pentoxifylline (PTX), electromagnetic fields (EMFs), and a mixture of both materials on bone fracture healing in a rat model.

Materials And Methods: Eighty male Wistar rats were randomly divided into four groups: Group A, femur fracture model with no treatment; Group B, femur fracture model treated with PTX 50 mg/kg/day intraperitoneal injection; Group C, femur fracture model treated with EMF 1.5±0.

Displaced lower third molar tooth into the submandibular space: Two case reports.

The aim of this article is to emphasize that the accidental displacement of a lower third molar during extraction is a rare, but potentially serious complication. We present two case reports on a lower third molar tooth dislodged into the submandibular space following its removal from the sockets and the subsequent management of this rare complication. Differences in the direction of displacement, the size of fragment, delay in retrieval, and tissue reactions can all influence this potential serious complication and hence no one technique is uniformly applicable.

Long-term effects of antihypertensive medications on bone mineral density in men older than 55 years.

Introduction: In this study, we investigated the effects of long-term antihypertensive treatment with calcium channel blockers or beta blockers on the bone mineral density of maxilla, as determined by cone-beam computed tomography (CBCT).

Material And Methods: This retrospective study was conducted on CBCT images of men older than 55 years who had received different dental indications. Data were grouped into three categories according to the antihypertensive medication history of the patients: group A included patients who had been taking beta-blocker treatment for more than 5 years, group B included patients who had been taking calcium channel blocker treatment for more than 5 years, and the control group included patients who had never used any hypertensive medications before.

A comparison of the effects of methylprednisolone and tenoxicam on pain, edema, and trismus after impacted lower third molar extraction.

Background: The aim of the present study was to compare the effects of preemptive intravenous tenoxicam and methylprednisolone administrations on extraction of impacted third molars.

Material And Methods: This was a placebo-controlled, randomized, double-blind, clinical trial. A total of 60 adult patients ages 18-40 years with the complaints of impacted third molar teeth were included in the study.

Parapagus dicephalus dibrachus dipus: A case of conjoined twins.

In this report, we describe the case of a woman with a prenatal diagnosis of parapagus dicephalus dibrachus dipus conjoined twins at 14-15 weeks of gestation via two-dimensional ultrasonography. The parents elected to terminate the pregnancy and the patient delivered a 15-cm 130-g male fetus. There were two heads and necks which appeared grossly normal.
