OBJECTIVES To study the validity of both rheumatological and orthodontic examinations and ultrasound (US) as screening methods for early diagnosis of TMJ arthritis against the gold standard MRI. METHODS Thirty consecutive juvenile idiopathic arthritis (JIA) patients were included in this pilot study. Rheumatological and orthodontic examinations as well as(More)
The aim of this study was to evaluate changes in the pharyngeal airway in growing children and adolescents and to compare these with a group of children who received activator-headgear Class II treatment. The sample consisted of 64 children (32 males and 32 females), 32 had a combined activator-headgear appliance for at least 9 months (study group) followed(More)
Surgically assisted rapid maxillary expansion (SARME) has become a widely used and acceptable means to expand the maxilla in adolescents and adult patients. The method takes advantage of bone formation at the maxillary edges of the midline, while they are separated by an external force. The purpose of the present retrospective investigation was to evaluate(More)
In adults, superior repositioning of posterior maxilla with or without mandibular surgery has become the treatment method of choice to close anterior open bite. Study aim was to examine the long-term stability of anterior open bite closure by superior repositioning of maxilla or by combining maxillary impaction with mandibular surgery. The sample comprised(More)
UNLABELLED The purpose of this study was to examine craniofacial morphology, pharyngeal airway space and hyoid bone position in preschool children with sleep-related breathing disorder associated with hypertrophy of tonsils (SBDT). Thirty-eight preschool children, mean age 4.7 y, with SBDT and with an apnoea index (AI) of 0 < AI < 5, were divided into two(More)
It has been maintained that because of large adenoids, nasal breathing is obstructed leading to mouth breathing and an 'adenoid face', characterized by an incompetent lip seal, a narrow upper dental arch, increased anterior face height, a steep mandibular plane angle, and a retrognathic mandible. This development has been explained as occurring by changes(More)
INTRODUCTION The aim of this study was to determine the accuracy of cone-beam computed tomography (CBCT) with different voxel resolutions. Measurements were made of the bony covering of the mandibular anterior teeth because this region is crucial in orthodontic treatment planning. METHODS CBCT data at 2 resolutions (0.125-mm and 0.4-mm voxels) were(More)
Deviations in the growth of the mandibular condyle can affect both the functional occlusion and the aesthetic appearance of the face. The reasons for these growth deviations are numerous and often entail complex sequences of malfunction at the cellular level. The aim of this review is to summarize recent progress in the understanding of pathological(More)
The shape of the craniofacial complex was analysed cephalometrically in sixty-four adult 45,X females (Turner syndrome) using lateral skull radiographs, and the subjects were compared with first-degree female relatives and control females. The results showed that 45,X females have marked changes in relatively few craniofacial areas compared to the controls.(More)
The aim of this study was to investigate the validity of hand-wrist radiographic analysis in estimating the amount of remaining craniofacial growth. The material compromised cephalograms of 22 males and 27 females with a Class I malocclusion. The median age of the females at the beginning (T1) was 11 years 10 months and of the males 12 years 6 months and at(More)
