The aims of this study were to test whether the shear bond strengths (SBS) of three commercially available colour change adhesives (CCAs), Transbond Plus Color Change Adhesive, Grēngloo, and Blūgloo, are different and to compare their bond strengths with a traditional light cure adhesive, Light Bond. Forty-eight human permanent premolar teeth extracted for(More)
OBJECTIVE To evaluate and compare the sizes of teeth in mild and severe hypodontia patients with those of healthy controls. MATERIALS AND METHODS Dental casts of 154 patients with two or more congenitally missing teeth were obtained. Patients were divided into two groups according to severity of hypodontia. Group I (mild) consisted of 118 patients with(More)
OBJECTIVE To evaluate the effects of severity and location of nonsyndromic hypodontia on craniofacial morphology. MATERIALS AND METHODS A total of 154 patients with at least two or more congenitally missing teeth were selected and divided into two groups (group I [mild]: patients with two to five missing teeth; group II [severe]: patients with six or more(More)
OBJECTIVES To evaluate the effects fluorosis and self etching primers (SEP) on shear bond strengths (SBS) of orthodontic brackets. METHODS A total of 48 (24 fluorosed and 24 non-fluorosed) non-carious freshly extracted human permanent premolar teeth were used in this study. Fluorosed teeth were selected according to the modified Thylstrup and Fejerskov(More)
The volume of air passing through the nose and nasopharinx is limited by its shape and diameter. Continuous airflow through the nasal passage during breathing induces a constant stimulus for the lateral growth of maxilla and for lowering of the palatal vault. Maxillary morphological differences exist between patients with airway problems and control groups,(More)
OBJECTIVE The aim of this study was to evaluate and compare the effects of rapid maxillary expansion (RME) and surgically assisted RME (SARME) in the sagittal, vertical, and transverse planes. STUDY DESIGN Orthodontic records of 28 patients were selected retrospectively and divided into two treatment groups. Group 1 comprised 14 patients (4 boys, 10(More)
OBJECTIVE To test the null hypothesis that no differences exist in craniofacial morphology between patients with familial Mediterranean fever (FMF) and the healthy population. MATERIALS AND METHODS Standardized lateral cephalograms of 32 FMF patients (mean age, 11.50 ± 2.72 years) and 32 healthy controls (mean age, 11.86 ± 2.19 years) were obtained.(More)
OBJECTIVE This study aimed to compare the cephalometric characteristics of obstructive sleep apnea (OSA) patients with those of healthy subjects and to determine possible relationships between cephalometric measurements of OSA patients and control subjects. METHODS Standardized lateral cephalograms of 16 OSA patients and 16 healthy controls were obtained.(More)
OBJECTIVE The aim of this study was to evaluate the applicability of Greulich and Pyle (GP) method for Southern Turkish population. MATERIALS AND METHODS Hand and wrist radiographs of 535 patients (276 females, 259 males aged from 10 to 18 years) selected retrospectively from the archive. Skeletal age (SA) estimation was performed according to GP atlas.(More)
OBJECTIVE To evaluate the skeletal, dentoalveolar, and soft tissue effects of skeletally anchored Class II elastics and compare them with a matched control group treated by a monobloc appliance for the correction of skeletal Class II malocclusion due to mandibular retrusion. MATERIALS AND METHODS Twelve patients (6 girls, 6 boys) were randomly divided(More)
