Epidermoid Cyst of the Floor of the Mouth.

Epidermoid cysts are rare, slow-growing, benign, developmental cysts that are derived from abnormally situated ectodermal tissue. Epidermoid cysts may grow anywhere on the body and about 7% of them are located in the head and neck region. They are usually asymptomatic over years but can be symptomatic due to secondary changes or the growing size.

Uncommon benign tumour of the skin: infraorbital pilomatricoma.

Pilomatricoma is a relatively rare tumour of the skin derived from primitive basal cells of epidermis that differentiate into hair matrix cells. It comprises approximately 1% of all benign skin tumours. The most common sites for pilomatricomas are the head, neck and upper extremities.

Gnathic osteosarcomas, experience of four institutions from Turkey.

Osteosarcoma is the most frequent primary gnathic sarcoma. Neither the etiology nor the variables effecting the prognosis are fully known due mostly to the rarity of gnathic osteosarcomas. To date a considerable number of clinicopathologic features have been suggested in the evaluation of gnathic osteosarcomas.

Effects of systemic zoledronic Acid administration on osseointegration of hydroxyapatite-coated and resorbable blast material surface implants in rabbit models.

Purpose: It is unknown whether zoledronic acid (ZA) interferes with initial bone healing at implant sites. The goal of this study was to examine the effects of systemic zoledronic acid administration on osseointegration of hydroxyapatite (HA)-coated and resorbable blast material surface (RBM) implants in rabbit models.

Materials And Methods: Twenty-eight male New Zealand rabbits (aged 6 to 12 months) were used in this study.

Mandibular fractures: a comparative analysis between young and adult patients in the southeast region of Turkey.

Objective: The purpose of this study was to review and compare the differences between mandibular fractures in young and adult patients.

Material And Methods: Patients treated at the Oral and Maxillofacial Department of Dicle University during a five-year period between 2000 and 2005 were retrospectively evaluated with respect to age groups, gender, etiology, localization and type of fractures, treatment methods and complications.

Results: 532 patients were included in the study, 370 (70%) males and 162 (30%) females, with a total of 744 mandibular fractures.

Total relaxivities of material content in various cysts and ameloblastoma: implications for discriminating different fluids.

Nuclear magnetic resonance T(1) and T(2) relaxivities (r(1) and r(2)) exhibit efficiency of a material to alter the relaxation rates (1/T(1) and 1/T(2)), and they are being used for diagnostic purposes. The determination of total relaxivities (r(1t) and r(2t)) of cystic fluid content and ameloblastoma may therefore be useful for discriminative purposes. In order to determine what makes total relaxivities of hemorrhagic cysts, four sets of tubes containing pooled cyst were doped with increasing concentrations of iron, copper, albumin, and gamma-globulins.

A clinical study on ankylosis of the temporomandibular joint.

Introduction: Restoration of normal function and jaw movement in patients with temporomandibular joint (TMJ) ankylosis is difficult. Various techniques have been defined for the treatment of the condition.

Patients: This study is based on the pre-, intra- and post-operative evaluation of 78 TMJ operations in 59 patients who were treated for TMJ ankylosis between 1985 and 2002.

The contribution to success of various methods of treatment of temporomandibular joint ankylosis (a statistical study containing 24 cases).

Temporomandibular joint (TMJ) ankylosis is an important joint disorder which, in addition to emerging through trauma, can also arise as a result of local and systemic infections. TMJ ankylosis which develops in childhood in particular has its own characteristics. Despite the existence of different views on the treatment of TMJ ankylosis, various techniques have been defined, and three basic techniques are currently employed: gap arthroplasty, interpositional arthroplasty and joint reconstruction.

Maxillofacial fractures. Analysis of demographic distribution and treatment in 2901 patients (25-year experience).

Introduction: The aim of this study was to analyse retrospectively the demographic distribution, treatment modalities, and complications of maxillofacial fractures in 2901 patients treated in this department in Southeast Anatolia between 1978 and 2002. In addition, the use of internal fixation was evaluated in an effort to determine whether there were changes in using internal fixation techniques.

Patients And Methods: Two thousand nine hundred and one cases of facial trauma were assessed according to age, sex, and aetiology, in addition to the distribution of the fractures relating to facial bones and seasons.

Tumors of the maxillofacial region in children: retrospective analysis and long-term follow-up outcomes of 90 patients.

The aim of this study was to carry out a retrospective analysis of maxillofacial tumors in children and to present the long-term follow-up results. Our study was performed with a retrospective analysis of 90 patients under the age of 15 years with maxillofacial tumor treated in our clinic between 1985-2002. In addition, treatment modalities and long-term follow-up results of these patients were evaluated.
