The effects of dental pulp stem cells on bone regeneration in rat calvarial defect model: micro-computed tomography and histomorphometric analysis.

Objective: Stem cell therapies may be applicable to all fields of medicine, including craniomaxillofacial surgery. Dental pulp stem cells also have significant osteogenic properties. This study aimed to evaluate the influence of dental pulp stem cells on bone regeneration and to ascertain whether or not there was any superiority over traditional methods.

Evaluation of "all-on-four" concept and alternative designs with 3D finite element analysis method.

Purpose: The aim of the present study was to evaluate the effect of the forces on the implant and supporting alveolar ridge in "all on four" concept and alternative designs using finite element analysis.

Materials And Methods: Different treatment alternatives with various implant designs were performed in an edentulous mandible. In Design 1, implants were placed according to "All-on-Four" concept; Design 2, two long (13 mm long, 4 mm diameter) and two short (7 mm long, 4 mm diameter) implants; Design 3, four long and two short implants; and Design 4, two long and four short implants were placed vertically.

Comparative investigation of the effects of different materials used with a titanium barrier on new bone formation.

Objectives: In this study, we aimed to study the effects on new bone formation of autogenous blood, deproteinized bovine bone graft (DBBG), and biphasic calcium phosphate (BCP) bioceramic graft materials placed under titanium barriers.

Material And Methods: Twenty-four adult male New Zealand white rabbits were used in this study. Two titanium barriers were fixed on each rabbit's calvarium.

Stabilization of autotransplanted teeth using thermoplastic retainers.

Objective: Different fixation techniques have been used for stabilization of autotransplanted teeth. Because rigid or extended fixation periods can cause complications such as ankylosis and disturbances of pulpal revascularization, our aim was to evaluate an alternative technique, a removable splint, for improving the success rate of autotransplanted molar teeth.

Study Design: In 44 patients, (20 male and 24 female patients), 45 transplanted teeth were analyzed.

Neoplasms of the salivary glands in a Turkish adult population.

Objective: This retrospective study aimed to investigate the types and distribution of neoplasm of salivary glands in a Turkish population.

Study Design: The histological diagnosis records of the Department of Pathology at Cumhuriyet University were reevaluated for 125 patients who were treated for salivary gland tumors from 1987 to 2008. The neoplasms were analyzed for histological diagnosis, age, sex, and site.

Experience of maxillary sinus floor augmentation in the presence of antral pseudocysts.

Sinus floor elevation is increasingly being used with implant placement procedures. However, certain surgical difficulties can develop, such as sinus membrane perforation, bleeding, anatomic variations, or some pathologies of the maxillary sinus. Maxillary antral pseudocysts are one of the most common benign pathologies of the maxillary sinus.

Analgesic and anti-inflammatory effects of oxaprozin and naproxen sodium after removal of impacted lower third molars: a randomized, double-blind, placebo-controlled crossover study.

Purpose: In this study, oxaprozin, a long-acting nonsteroidal anti-inflammatory drug, and naproxen sodium were compared in terms of their effects on edema, pain, and trismus after surgery for impacted mandibular third molars.

Materials And Methods: Thirty healthy patients with bilaterally impacted mandibular third molars were included in this randomized, cross-over, double-blind, placebo-controlled study. Patients were assigned randomly to 1 of 3 surgery groups and received postoperatively 1,200 mg oxaprozin, 550 mg naproxen sodium, or a placebo.

Prevalence study of signs and symptoms of temporomandibular disorders in a Turkish population.

Aim: The aim of this study was to evaluate the prevalence of signs and symptoms of temporomandibular disorders (TMD) in a population of 792 Turkish adults ranging in age from 15- to 72-years-old.

Methods And Materials: Subjects were examined objectively and subjectively for signs and symptoms of TMD through the distribution of frequency of the data obtained from a questionnaire and a physical examination using a similar methodology of previous studies.

Results: This study determined the prevalence of signs and symptoms of TMDs in subjects from male and female subgroups in a Turkish adult population.

Penetration depth of laser Doppler flowmetry beam in teeth.

Objective: The aim of this study was to determine the penetration depth of laser light in teeth for contact and noncontact probe tip.

Study Design: Fifty-one freshly extracted human mature maxillary and mandibular single rooted teeth were selected for the study. A laser Doppler flowmeter was used as a laser source.

Effect of gingiva on laser doppler pulpal blood flow measurements.

The purpose of this study was to evaluate the effect of labial and palatinal gingiva on laser Doppler pulpal blood flow measurements. Twenty upper central incisor teeth determined to be vital from 20 volunteers were included into the study. To stabilize the probe, a laboratory-made acrylic splint positioned the probe labially on the cervical third of the tooth crown.

The sources of laser Doppler blood-flow signals recorded from vital and root canal treated teeth.

Objectives: The aim was to determine the strength of signals derived from the dental pulp and those from the surrounding tissues in human teeth using the laser Doppler flowmetry (LDF).

Methods: Twenty-six vital teeth (13 experimental and 13 controls) from 12 patients were used. Experimental teeth had root canal treatment in a single visit and their healthy antimeres were controls.

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.
