Obstructive sleep apnea severity and dental arches dimensions in children with late primary dentition: An observational study.

: The aim of this study was to compare the dimensions of the upper and lower arches in children affected by OSAS with different levels of severity of obstruction.: Twenty-seven Caucasian children (14 males, 13 females; mean age 6, range 5.2-6.

Rapid maxillary expansion outcomes in treatment of obstructive sleep apnea in children.

Objectives: The objectives of this study were to confirm the efficacy of rapid maxillary expansion in children with moderate adenotonsillar hypertrophy in a larger sample and to evaluate retrospectively its long-term benefits in a group of children who underwent orthodontic treatment 10 years ago.

Methods: After general clinical examination and overnight polysomnography, all eligible children underwent cephalometric evaluation and started 12 months of therapy with rapid maxillary expansion. A new polysomnography was performed at the end of treatment (T1).

Rapid maxillary expansion in children with Obstructive Sleep Apnoea Syndrome (OSAS).

Aim: to evaluate the effects of rapid maxillary expansion (RME) in a group of OSAS preschool children.

Materials And Methods: Lateral cephalograms of 15 OSAS children (8 boys and 7 girls, age mean ± SD: 5.94 ± 1.

Efficacy of rapid maxillary expansion in children with obstructive sleep apnea syndrome: 36 months of follow-up.

Purpose: In view of the positive outcome of orthodontic treatment using rapid maxillary expansion (RME) on sleep-disordered breathing, we generated data on RME in children with obstructive sleep apnea (OSA) by evaluating objective and subjective data over a 36-month follow-up period, to determine whether RME is effective in the long-term treatment of OSA. We selected all patients with dental malocclusions and OSA syndrome (OSAS) confirmed by polysomnography.

Methods: Ten of the 14 children who completed the 12-month therapeutic trial using RME were enrolled in our follow-up study.

Craniofacial morphology in preschool children with obstructive sleep apnoea syndrome.

Aim: Obstructive sleep apnoea syndrome (OSAS) is a common problem in children. It is characterised by a combination of partial airway obstruction associated with hypoxemia and hypoventilation and intermittent obstructive apnoea, which disrupts normal ventilation and sleep. The aim of the study was to evaluate the craniofacial features of preschool children with polysomnographic diagnosis of OSAS, using measurements from standardized lateral cephalograms according to the floating norms cephalometric analysis.

In vitro evaluation of the efficacy of a new laser surface implant: cellular adhesion and alkaline phosphatase production tests.

Bone tissue reacts in different ways to implant surfaces with different patterns. The aim of this study is to understand which laser generated surface pattern produces the best cell adhesion in vitro, evaluating both the activity of the alkaline phosphatase and the cells adhering to titanium samples. Tests were carried out on titanium samples with sandblasted surfaces with laser-produced holes with diameters of 5, 10, and 20 microm, and on sandblasted titanium cylinders without holes as controls.

Rapid maxillary expansion for the treatment of nasal obstruction in children younger than 12 years.

Objective: To assess short- and long-term effects of rapid maxillary expansion (RME) on nasal flow in young children. Since RME has been reported to positively influence nasal obstruction in subjects with respiratory problems by reducing nasal resistance, a similar efficacy of RME could be expected in children with deciduous and/or mixed dentition who are affected by maxillary constriction and nasal obstruction from a different cause.

Design: Prospective study of children younger than 12 years, with different grades of malocclusion and oral breathing.

Rapid maxillary expansion in children with obstructive sleep apnea syndrome: 12-month follow-up.

Objectives: To assess the outcome of rapid maxillary expansion in the treatment of obstructive sleep apnea syndrome (OSAS) in children, we studied 16 patients (mean age 6.6+/-2.0; 9 males) with dental malocclusion, a body mass index < or =85 percentile, and OSAS confirmed by polysomnography.

[Pulpal effects of etching in the use of direct attachments].

Recurring enamel etching was observed to value the effects on pulp response. Four teeth were extracted and analysed by O.M.

[Evaluation of upper arch dimensions in subjects with palatally impacted canines].

A sample of patients with palatally displaced cuspids and a sample of subjects with normally erupted maxillary cuspids were examined as far as arch dimention and tooth size are concerned.

[Beckwith-Wiedemann syndrome. A rare case].

The Authors describe a case of Beckwith-Wiedemann syndrome. In this patient marked macroglossia and mandibular prognatism are presented.

[Radiographic localization of the impacted cuspid in the upper maxilla].

A review of radiological diagnostic aids for maxillary impacted cuspid is presented.

[Evaluation of dental age using qualitative radiographic analysis. 2].

The Authors evaluated the stage of growth of seven left mandibular teeth and their eruption sequence on 157 op. The growth accomplishment happened earlier in this study as compared to others. Males showed one year gap compared to females in reaching the full dental growth, identified by the apex closure.

[Evaluation of dental age using qualitative radiographic analysis 1].

The authors analyzed 157 OP taken from growing subjects evaluating either the stage of development, or the maturity index of the seven left mandibular teeth. The dental age of each subject has been related to chronological age.

[Role of soft tissue in orthodontic diagnosis. 1].

The Authors propose a review of the soft-tissue cephalometric analysis, to show its diagnostic usefulness.
