statement of problem: condylar hyperplasia of the mandible is a self limiting abnormality which can cause facial asymmetry, temporomandibular joint (tmj) dysfunction and esthetic problems. treatment planning is based on the results of isotope scanning, clinical findings and patient age. single photon emission tomography (spect) is considered to be a sensitive method in the calculation of condyl...

BACKGROUND The standard bifrontal application of the bispectral index (BIS) sensor interferes with the operative field in neurosurgery and plastic surgery. The aim of this study was to compare the standard frontal BIS sensor position with an alternative position across the mandible. METHODS Two BIS™ Quatro sensors (Aspect Medical Systems, Newton, MA, USA) mounted on the frontal and mandibular...

BACKGROUND The aim of this study was to determine the association between facial pattern according to Ricketts cephalometric analysis, and prevalence of third molar agenesis, taking subject age and gender as control variables. MATERIAL AND METHODS An epidemiological survey was conducted based on a sample of 224 candidates for orthodontic treatment aged 12 to 24 (n=224). Third molar agenesis w...

A study was undertaken to examine the relationship between the clinical signs and symptoms of temporomandibular joint (TMJ) disorder and computed tomographic (CT) evidence of destruction of these joints in children afflicted with juvenile rheumatoid arthritis (JRA). A thorough clinical examination including determination of the craniomandibular index (CMI) was performed on each of 37 consecutiv...

OBJECTIVES This study aimed to evaluate the healing rate of non-surgical endodontic treatment between C-shaped and non-C-shaped mandibular second molars. MATERIALS AND METHODS Clinical records and radiological images of patients who had undergone endodontic treatment on mandibular second molars between 2007 and 2014 were screened. The periapical index scoring system was applied to compare hea...

PURPOSE Although there have been several studies of reduced airway space after mandibular setback surgery using the sagittal split ramus osteotomy technique, research on the risk factors for changes of the airway space is lacking. Therefore, this study was performed to examine airway changes and the position of the hyoid bone after orthognathic surgery, and to assess possible risk factors. ME...

The number of obese adolescents is increasing in the Western society. For a deeper understanding of the mechanisms underlying this pathology, the quantitative characteristics of the facial soft tissues should also be investigated. The three-dimensional coordinates of 12 soft tissue facial landmarks were obtained by computerized digitizers in 11 male and 14 female adolescents aged 13-17 years, a...

PURPOSE This study was performed to analyze human maxillary and mandibular trabecular bone using the data acquired from micro-computed tomography (micro-CT), and to characterize the site-specific microstructures of trabeculae. MATERIALS AND METHODS Sixty-nine cylindrical bone specimens were prepared from the mandible and maxilla. They were divided into 5 groups by region: the anterior maxilla...

This prospective, cohort study evaluated the role of sleep nasendoscopy (SNE) with simultaneous mandibular protrusion in predicting successful mandibular advancement splint (MAS) therapy in subjects with obstructive sleep apnoea (OSA). Nineteen OSA subjects diagnosed by overnight polysomnography were referred for MAS therapy, following SNE investigation. A Herbst MAS was fabricated for each sub...

PURPOSE This case series evaluated the implant success rate and peri-implant tissue response of immediately loaded unsplinted implants retaining a mandibular overdenture. MATERIALS AND METHODS Eight completely edentulous patients (five men, three women) with a mean age of 69.1 years were included in the study. All participants received new maxillary and mandibular complete dentures prior to i...
