Abstract Objective: To apply both conventional cephalometric analysis and morphometric analysis (thin-plate spline analysis) to posteroanterior (PA) cephalograms to test the hypothesis that the dentoskeletal features of subjects with anterior open bite in the mixed dentition are no different from those of normal controls. Materials and Methods: A group of 22 white subjects (6 males, 16 females; mean age, 8.7 ± 0.7 years) with anterior open bite (AOBG) was compared with a control group (CG) of 22 white subjects (11 males, 11 females; mean age, 9.2 ± 0.8 years) with Class I occlusal relationships, and without anterior open bite and sucking habits. Subjects of both groups were in the mixed dentition and had no history of orthodontic treatment. Between-group statistical comparisons were performed with independent sample t-tests and permutation tests. Results: AOBG exhibited statistically significant shape differences with respect to CG that consisted of a transverse contraction of the zygomatic region, of the maxilla (at both skeletal and dentoalveolar levels), and of the mandible (in both condylar and gonial regions), with a downward dislocation of point menton. With conventional cephalometrics, AOBG showed a statistically significant transverse deficiency in the zygomatic region (−4.8 mm), in the maxilla at both skeletal and dentoalveolar levels (−2.0 mm and −3.0 mm, respectively), and in the mandible in both condylar and gonial regions (−3.6 mm and −4.0 mm, respectively). Conclusion: Subjects with anterior open bite showed transverse deficiencies in the zygomatic region, in the maxilla, and in the mandible when compared with normal subjects.

ABSTRACT Objective:  To evaluate the overbite correction of fixed palatal crib (FPC) and bonded lingual spur (BLS) in the early treatment of anterior open bite (AOB) in mixed dentition (primary outcome) as well as its influence on dental and skeletal cephalometric measurements (secondary outcome). Materials and Methods:  The selected patients had AOB and a mean age of 8.23 years. They were divided into the following three groups by casting lots: control (n  =  13), palatal crib (n  =  13), and spur (n  =  13). Data from the lateral teleradiography was obtained at the beginning, at 6 months, and after 1 year. The cephalometric analysis was performed by Cef-X program, recording the values of SNA, SNB, ANB, SnG oGn, 1.PP, IMPA, nasolabial angle, overbite, and overjet. Intergroup and intragroup comparisons were obtained via one-way analysis of variance. Results:  The degree of AOB was similar at baseline (P > .05). At 6 months and then after 1 year all groups showed improvement in the overbite. However, only the crib and spur groups showed positive overbite. No cephalometric measurements changed significantly over the period analyzed. Conclusions:  We conclude that the FPC and BLS are simple and effective for the treatment of anterior open bite, with the advantage given to the FPC.

This case report intends to provide the facial characteristics of Escobar syndrome and to describe the orthodontic treatment of a 12-year-old female patient diagnosed with it. Escobar syndrome, a variant of the multiple pterygium syndrome, is a rare disorder with many systemic, facial, and oral manifestations.The patient presented with mixed dentition, severe dolichofacial pattern, increased lower facial height, convex profile, severe anterior open bite, maxillary hypoplasia, and mandibular retrognatism. The multidisciplinary approach included soft cleft palate repair, orthodontic treatment, orthognathic surgery, restorative cosmetic dentistry, speech therapy, and physiotherapy. Despite the limitations imposed by the syndrome, this report illustrates how the multidisciplinary treatment approach aided in the correction of occlusal function and facial esthetics and improvement in the quality of life of the patient with Escobar syndrome.

The aim of the study was to explore the basic features of self-schema in persons with schizophrenia. Thirty two schizophrenic patients and 32 normal controls were asked to select personality trait words from a check-list that described themselves, themselves as they were five years ago, and what most people are like. Compared with the control group, participants from the experimental group chose significantly more adjectives that were common to descriptions of self and others, and significantly less that were common to self and past-self descriptions. These results suggest that schizophrenic patients experience their personality as changing over time much more than do healthy subjects. Moreover, their self-representation seems to be less differentiated from others-representation and less clearly defined than in normal subjects.

Abstract A 32-year-old Japanese female patient consulted the authors' dental clinic with a 4.5-year history of rheumatoid arthritis (RA). She complained of pain during mouth opening and difficulty in eating due to masticatory dysfunction caused by an anterior open bite. Imaging showed severe erosion and flattening of both condyles. RA stabilized after pharmacological therapy and became inactive during the orthodontic therapy aimed at reconstructing an optimal occlusion capable of promoting functional repositioning of the mandible. At present, 4 years and 2 months postretention, the reconstructed occlusion remains stable, and both condyles continue to be remodeled. The distance from reference position to intercuspal position has gradually decreased throughout the 4-year posttreatment and postretention periods. Orthodontic therapy that comprehensively reconstructs occlusion and enhances the functioning of the mandible can induce remodeling of eroded condyles, even those with a history of rheumatoid arthritis.

Saccadic and smooth pursuit eye movements were recorded in three groups of subjects: a schizophrenic group, a non-schizophrenic psychotic patient comparison group, and a normal control group. Schizophrenic subjects demonstrated a greater decrease in saccadic response time than did normal controls in a gap task (when the fixation point was turned off 150 msec before the target appeared). The psychiatric comparison subjects did not differ from normal controls. Further, only schizophrenic subjects demonstrated a relation between smooth pursuit and saccadic eye movement performance, such that subjects with impaired smooth pursuit showed a larger decrease in saccadic response time in the gap task. The relation between performance on the gap task and quality of smooth pursuit and its relevance for a prefrontal deficit hypothesis of schizophrenia are discussed.

And Control

Patients with open bite often show a weak occlusal force and temporomandibular disorders (TMDs). If these are the main cause of open bite, it may be hypothesized that both pre-pubertal and adult open-bite patients would show a weak occlusal force and abnormal condylar motion. The purpose of this study was to test this hypothesis. Test group subjects consisted of 13 consecutive pre-pubertal and 13 adult patients with anterior open bite. They were compared with age-matched normal subjects. The adult open-bite group showed a weaker occlusal force and a shorter range of condylar motion compared with the control subjects. In the pre-pubertal subjects, however, there were no significant differences in the occlusal force and range of condylar motion between the open-bite and control groups. Therefore, these results suggest that a weak occlusal force or TMDs may not be the main cause of open bite.

Case Report. An 8-year-old girl with amelogenesis imperfecta (AI) reported unsatisfactory aesthetics, difficulty in mastication, and dental hypersensitivity. The intraoral examination observed mixed dentition, malocclusion in anteroposterior relationships, anterior open bite, and dental asymmetry. A hypoplastic form of AI was diagnosed in the permanent dentition. A multidisciplinary planning was performed and divided into preventive, orthopedic, and rehabilitation stages. Initially, preventive treatment was implemented, with fluoride varnish applications, in order to protect the fragile enamel and reduce the dental sensitivity. In the second stage, the patient received an interceptive orthopedic treatment to improve cross-relationship of the arches during six months. Finally, the rehabilitation treatment was executed to establish the vertical dimension. In the posterior teeth, indirect composite resin crowns were performed with minimally invasive dental preparation. Direct composite resin restorations were used to improve the appearance of anterior teeth.Follow-Up. The follow-up was carried out after 3, 6, 12, and 18 months. After 18 months of follow-up, The restoration of integrity, oral hygiene, and patient satisfaction were observed .Conclusion. Successful reduction of the dental hypersensitivity and improvement of the aesthetic and functional aspects as well as quality of life were observed.

The nasal cycle in patients with septal deviation was studied by acoustic rhinometric techniques. This study included 24 patients with anteriorly located septal deviations (mean age = 23.5), and 26 normal controls (mean age = 24.7). Data of MCA (minimum cross-sectional area) and NV (nasal volume), collected in 20-minute intervals, were plotted for each subject during 8 hours. Twenty of 24 patients (83%) with septal deviation and 20 of 26 normal subjects (77%) showed at least one complete cycle. Duration of the nasal cycle, which ranged from 100 minutes to 400 minutes, had no statistical difference between the septal deviation group (mean duration of 216 minutes) and the normal control group (mean duration of 227 minutes). The degrees of variation of MCA and NV, defined as Degree of Variation of MCA (%) = 100 (MCAmax – MCAmin)/MCAmax, Degree of Variation of NV (%) = 100 (NVmax – NVmin)/NVmax, which represent the percent change of MCA and NV throughout the study, showed no difference between the wide side and the narrow side, or between the septal deviation group and the normal control group. These findings suggest that the nasal cycle is relatively independent of peripheral anatomic factors for its generation. However, the amplitude of changes of MCA was greater in the wide side, and the sum of both MCAs tended to fluctuate in accordance with the fluctuation of MCA of the wide side. Thus, the nasal cycle seemed to be affected by septal deviation.
