Class II Skeletal Malocclusion and Prevalence of Temporomandibular Disorders. An Epidemiological Pilot Study on Growing Subjects.

The purpose of our work is to evaluate the correlation between skeletal Class II malocclusion and temporomandibular disorders, by assessing potential different frequency scores compared with Class I and Class III skeletal malocclusion, and to evaluate associated etiological and risk factors. Fifty-five subjects were examined, 35 females and 20 males, with a mean age of 18 ± 1.3 years, divided into two groups: those with TMD and those without TMD, and prevalence was evaluated in the two groups of Class II subjects.

Prevalence of Early Childhood Caries in Southern Italy: An Epidemiological Study.

The purpose of this study was to assess the prevalence of Early Childhood Caries (ECC) and oral habits among preschool children from a southern Italian cohort. The survey population consisted of 300 subjects randomly selected among children attending two kindergartens in Catania, Italy. The prevalence of ECC and oral habits were clinically evaluated.

New Materials for Orthodontic Interceptive Treatment in Primary to Late Mixed Dentition. A Retrospective Study Using Elastodontic Devices.

The aim of this study was to assess the skeletal and dentoalveolar changes obtained after 1 year of treatment with elastodontic appliances (EA) in a retrospective cohort of children reporting early signs of malocclusion. Also, a detailed description of the tested EAs was reported. The study sample included 20 subjects, 8 males and 12 females, with a mean age of 8.

Craniomandibular Disorders in Pregnant Women: An Epidemiological Survey.

Temporomandibular joint (TMJ) disorder has been reported to be 1.5 to two times more common in women than men. Such a gender-based difference could be attributed to behavioral, hormonal, anatomical, and psychological characteristics.

Effectiveness of the passive lingual arch for E space maintenance in subjects with anterior or posterior rotation of the mandible: a retrospective study.

Objective: The aim of this study was to determine whether or not lingual arches in subjects with anterior or posterior mandible rotation can produce different effects in the prevention of first permanent molar mesial migration.

Subjects And Methods: Forty-two patients with a mean age of 9 ± 0.8 years were selected from the Department of Orthodontics, University of Catania, Italy.

Influence of straight-pull headgear on the eruption pattern of maxillary canines: a retrospective study.

Aim: To evaluate the effect of the straight-pull headgear and activator (Andresen type) treatment on the eruption pattern of impacted maxillary canines.

Methods: Mesiodistal positional, angular, and vertical changes of impacted canines were evaluated and statistically analyzed in pre- and posttreatment panoramic radiographs of 22 patients (12 treated with combination headgear, 10 treated with an activator).

Results: Eruption of the permanent canines in the group treated with straight-pull headgear was significantly more successful (88%) than in the group treated with an activator (62%).

Influence of first premolars extraction on vertical dimension in Italian patients with a Class I normo-divergent malocclusion. A retrospective study.

Objective: The purpose of this study was to examine the changes in vertical dimension occurring in Class I non-growing patients treated with first four premolars extraction and to test the hypothesis that the vertical dimension collapses after four first premolars extractions.

Material And Methods: Records of 28 patients (9 males and 19 females) treated with extraction of first four premolars were obtained. Pre-treatment and post-treatment lateral cephalograms were digitized, and 6 linear and 5 angular cephalometric measurements were selected to evaluate vertical changes.
