Morphological occlusal features following condylar fractures in children.

Early fracture of the mandibular condyles may be related to an asymmetric morphologic occlusion. The aim of the study was to investigate the morphologic occlusal symmetry of non-surgically treated children after condylar fractures. The original study group consisted of 55 subjects (31 males and 24 females) who suffered temporomandibular joint condylar fractures at a young age and were treated conservatively, with physiotherapy only.

External apical root resorption in patients treated by serial extractions followed by mechanotherapy.

Introduction: In the course of orthodontic treatment with serial extractions (SE), spontaneous unraveling of crowded incisors occurs. It was hypothesized that SE followed by mechanotherapy will cause less external apical root resorption (EARR) than orthodontic treatment with late extractions (LE).

Methods: The records of 24 patients who underwent SE and mechanotherapy and 24 control patients who underwent LE and mechanotherapy were examined.

Early headgear effect on the eruption pattern of maxillary second molars.

Objective: To test the hypothesis that the use of a combination headgear (HG) during the first phase of orthodontic treatment has no effect on the eruption pattern of the maxillary second permanent molars.

Materials And Methods: The records of the patients in a two-phase randomized clinical trial of early Class II treatment were utilized. The HG group comprised 47 patients, and the control (CON) group comprised 52 patients.

Methods: Pretreatment records of 221 patients with a mean age of 11.3 years were evaluated.

Occlusal patterns in patients with idiopathic scoliosis.

Introduction: Idiopathic scoliosis is an orthopedic condition characterized by faulty posture. It might also be associated with some mild forms of facial asymmetry or dental deviations. The aim of the study was to clinically examine the occlusions of patients with idiopathic scoliosis.

An oral health promotion program for the prevention of complications following avulsion: the effect on knowledge of physical education teachers.

The aim was to assess the knowledge levels of physical education teachers before and after a seminar, presented by dental faculty as part of a community outreach program, in which the need for immediate treatment because of avulsion of permanent teeth has been emphasized, and to compare knowledge levels of teachers who attended the seminar with those who did not. Physical education teachers attended a seminar presented by senior faculty of the Hebrew University-Hadassah School of Dental Medicine as part of an educational campaign in the community. The seminar included clear instructions on the appropriate treatment of avulsed permanent teeth, which were appropriate for physical education teachers.

Conservative adjunct to esthetic orthodontic treatment in young patients.

The esthetic effect of orthodontic treatment in young patients may sometimes be incomplete without performing additional procedures related to the form and texture of the anterior teeth. Six young patients, aged 7 to 21 years, presented for orthodontic treatment to improve their dental esthetics. The problems of tooth staining, mutilation, congenitally missing teeth, tooth size/arch length discrepancy, and sequellae of dental trauma neccessitated a combined orthodontic-prosthodontic treatment.

Nasal airflow and olfactory function after the repair of cleft palate (with and without cleft lip).

Objective: The objective of this study was to examine nasal airflow and olfactory functions in patients with repaired cleft palate compared with matching normal controls.

Study Design: The all-cleft group consisted of 25 patients with hard palate cleft comprising 15 patients with unilateral cleft palate and lip (UCLP); 2 with CP but no cleft lip (UCLP subgroup) and 8 patients with bilateral cleft lip and palate (BCLP subgroup). All had had surgical correction of the palate in infancy.

Congenitally missing teeth in the Israeli cleft population.

Objective: The purpose of the study was to determine the prevalence of congenitally missing teeth in a group of Israeli children with various types of clefts.

Psychophysical testing of taste and flavour reactivity in young patients undergoing treatment with removable orthodontic appliances.

Upper removable appliances (URA), as well as full dentures, are known to be the cause of various complaints related to oral handling of food and beverages, phonation and vocalization, in addition to general discomfort. To test the hypothesis that taste and flavour perception might also be affected by URA, 22 young orthodontic patients (10 males and 12 females aged 11.5 +/- 1.

Periodontal status following surgical-orthodontic alignment of impacted central incisors with an open-eruption technique.

Several factors may affect the outcome of the orthodontic/surgical modality for the resolution of impacted central incisors, but particularly the manner in which the impacted tooth is exposed. The present study aimed to evaluate the post-retention clinical appearance and periodontal status of impacted maxillary central incisors which were exposed and aligned with an open-eruption surgical-orthodontic technique. Twelve subjects (four males, eight females), aged 22 years (range 15-38 years), previously treated for a unilateral impacted central incisor (ICI), were examined 10 years (range 3-25 years) post-retention.

Skeletodental patterns in patients with multiple congenitally missing teeth.

Congenitally missing teeth (CMT) are a relatively frequent phenomenon. In severe cases of multiple CMT, the skeletodental pattern can be unique. However, the characteristics of this pattern are still controversial.

External apical root resorption in Class II malocclusion: a retrospective review of 1- versus 2-phase treatment.

External apical root resorption (EARR) is an imperfectly understood problem of orthodontic treatment. The records of 138 children with Class II malocclusion (overjet > 7 mm) participating in a randomized clinical trial of early orthodontic treatment were reviewed. The patients were treated in either 1 phase with fixed appliances only (n = 49) or 2 phases with headgear (n = 49) or bionator (n = 40) followed by fixed appliances.

The effect of functional occlusal forces on orthodontic tooth movement and tissue recovery in rats.

The influence of physiologic occlusal forces on tissue response to orthodontic tooth movement and its subsequent recovery was investigated in rats. The mandibular incisors were subjected to tipping and intrusive loads for 2 weeks. In 27 animals, the teeth remained in occlusion, while the incisors were shortened out of occlusion in 29.

Can maxillary incisor trauma be predicted from cephalometric measurements?

Dental injury is a traumatic event related to many factors, including dentofacial morphology. In a previous study in which we used a logistic regression model, 5 cephalometric variables were defined as being the best predictors of traumatic injury. The purposes of this study were to test the predictive value of the logistic regression analysis results for the occurrence of dental injury in a new patient sample and to compare these results with the outcome based on a visual evaluation of cephalograms.

The labiogingival notch: an anatomical variation of clinical importance.

Background: The labiogingival notch is a developmental phenomenon affecting the maxillary central incisors. Clinically, it can be easily misdiagnosed and improperly treated. Thus, it is important for dentists to recognize this condition.
