INTRODUCTION The aim of this study was to evaluate whether early loss of the permanent first molars has an effect on the developmental stages and eruptive conditions of the third molars. METHODS Panoramic radiographs and dental casts of 165 adolescent patients (103 boys, 62 girls) with unilateral early loss of a permanent first molar were used to assess(More)
The purpose of this study was to evaluate the longitudinal growth changes in the incisor position, overjet, and overbite between 10 and 14 years of age. Serial cephalometric radiographs of 63 subjects (31 boys and 32 girls) were taken at the ages of 10, 11, 12, and 14. The effects of age and gender on the incisor positions, overjet, and overbite were(More)
INTRODUCTION The purpose of this study was to determine the possible effects of genetic factors on facial proportions and soft-tissue profile characteristics in Turkish Anatolian siblings. METHODS The material consisted of lateral and posteroanterior cephalometric head radiographs of 138 siblings (70 women, 68 men) living 15 years or more in the province(More)
The purpose of this study was to determine the possible effect of genetic factors on Bolton tooth-size discrepancy. Subjects who applied for orthodontic treatment and their siblings (106 females and 78 males) were included in the study. The ages of the subjects ranged from 13 to 21 years. The siblings were grouped according to gender: male-male (24 pairs),(More)
The aim of this study was to investigate the relationship between the depth of the curve of Spee and positions of upper and lower incisors, overjet, overbite, and anterior lower crowding. The material consisted of lateral head films and dental casts of 137 untreated adolescent subjects, 76 girls and 61 boys, aged 13 to 16 years. The subjects were divided(More)
BACKGROUND It has been suggested that overjet may be related to the form of the maxilla and mandible. AIMS The aims of this study were to compare the gender differences in the maxillary and mandibular morphology in different overjet groups, and to determine the associations between overjet and craniofacial morphology in the same subjects. METHODS The(More)
Longitudinal growth changes in the transverse and vertical craniofacial dimensions occurring between 10 and 14 years of age were evaluated in 22 female and 23 male subjects. All subjects were healthy, had a clinically acceptable occlusion, and had not received orthodontic or orthopedic therapy before. Serial cephalometric radiographs were taken at ages 10,(More)
OBJECTIVE To evaluate the skeletal effects of nonsurgical rapid maxillary expansion (RME) on craniofacial structures with bone scintigraphy in young adult female subjects. MATERIALS AND METHODS The material of the present study consists of scintigraphic records taken from 17 early adult females treated with RME. All patients had a bilateral posterior(More)
An adult male patient who had lost his maxillary left central incisor seven years ago in a traffic accident presented with a chief complaint about his unaesthetic appearance associated with the loss of his maxillary left central incisor space, a Class III molar occlusion, and an anterior open bite malocclusion due to tongue-thrust swallowing. Fixed(More)
OBJECTIVE To test the hypothesis that use of cervical headgear has an important effect on the morphology of the cervical vertebrae and cervical posture. MATERIALS AND METHODS The material consisted of pretreatment and posttreatment lateral cephalograms and initial hand-wrist films of 30 subjects who were receiving cervical headgear therapy.
