Relationship between Cervical Spine and Skeletal Class II in Subjects with and without Temporomandibular Disorders.

Aim: To assess changes in the craniocervical structure and in hyoid bone position in skeletal Class II subjects with and without temporomandibular disorders (TMD).

Materials And Methods: The cephalometric analysis of 59 subjects with skeletal Class II was evaluated and compared. The measurements considered were ANB as a parameter of Class II and C0-C1 distance, C1-C2 distance, craniocervical angle, and hyoid bone position for the cervical spine analysis.

Variable torque prescription: state of art.

The variable prescription is widely described under the clinical aspect: the clinics is the result of the evolution of the state-of-the-art, aspect that is less considered in the daily literature. The state-of-the-art is the key to understand not only how we reach where we are but also to learn how to manage propely the torque, focusing on the technical and biomechanical purpos-es that led to the change of the torque values over time. The aim of this study is to update the clinicians on the aspects that affect the torque under the biomechanical sight, helping them to understand how to managing it, following the "timeline changes" in the different techniques so that the Variable Prescription Orthodontic (VPO) would be a suitable tool in every clinical case.

Personality and psychopathology in patients with temporomandibular joint pain-dysfunction syndrome. A controlled investigation.

Objective: Our aim was to deepen the understanding of the psychosomatic aspects of temporomandibular joint (TMJ) pain dysfunction syndrome. Patients affected by this syndrome were compared with both healthy subjects and psychiatric patients, using both self-report and physician-scored psychological measures.

Methods: Three sex- and age-matched groups were recruited: a TMJ group (n = 32), a healthy group (n = 22) and a psychiatric group (n = 22).

[The Papillon-Lefèvre syndrome. A clinical and ultrastructural study of 2 cases].

Two cases of Papillon-Lefèvre syndrome, a rare hereditary affection of unknown etiology, whose clinical signs are hyperkeratosis palmoplantaris and parodontitis, are described. The results obtained with the ultrastructural examination of the lesions are shown. A therapeutic protocol which can reduce the evolution of the pathology, is also suggested.

[Classification and etiopathogenesis of upper canine impaction].

Classification and aetiopathogenesis of upper canine inclusion. The possible causes of upper canine inclusions are reviewed. After a detailed description of the factors that generally contribute to determining inclusions, it is stressed that correct aetiopathogenetic classification of this pathology can contribute to making the complex protocol for its treatment easier.
