[Could the distalization of the mandibular molars be facilitated? A new therapeutic method].

A young patient complained of missing inferior second premolars. Clinical and cephalometric parameters suggested the indication for a prosthetic solution, opening the spaces between first premolars and molars, aiming to correct occlusal relationships. Space closure was thus excluded.

Orthodontists' perspectives regarding treatment timing: a cross-national study.

Aim: To describe the results of a cross-national survey of orthodontists' preferences regarding initiating treatment at various dentition stages. Previous research has demonstrated high acceptance of early intervention by parents and children, and, in many cases, better compliance with treatment protocols among younger children than among adolescents.

Methods: The current study questioned orthodontists in three countries.

Extractions as a form of interception in the developing dentition: a randomized controlled trial.

Objective: To determine if the extractions of lower primary canines are an effective procedure to relieve crowding of the labial segment.

Study Design: randomized controlled trial. Subject sample: 83 cases were collected in clinics in Italy, Germany and Wales.

4.2 Clinical records and global diagnostic codes.

A clinical record should include the personal demographic details of the patient, health status, diagnostic information and management/treatment options. However, clinical records are of little use without effective filing and retrieving systems. Coding is therefore necessary to deal with large amounts of differing data and a global coding system could be effectively developed through the use of information technology.

Bone response to orthodontic loading of endosseous implants in the rabbit calvaria: early continuous distalizing forces.

The purpose of this experimental study was to evaluate the effect of early orthodontic loading on the stability and bone-implant interface of titanium implants in a rabbit model. Twenty-four short threaded titanium fixtures were inserted in the calvarial mid-sagittal suture of 10 rabbits. Two weeks following insertion, 20 implants (test group) were subjected to continuous distalization forces of 150 g for a period of 8 weeks.

[Prevention in dentistry: evaluation after one year].

The Authors planned an after one year revision of a sample of no. 138 children of a ULSS 8 (VI) District, involved in a odontoiatric prevention program.

[Epidemiological study and orthodontics].

Prevention is now playing a major role in all fields. An epidemiological survey of malocclusions has evaluated 6 years old children in one district in the Regione Veneto (Northern Italy). Some indications are provided as regards preventive and interceptive orthodontics (including treatment aimed to reducing the severity of problems) in the therapy of the most frequent malocclusions in this age group.

[Epidemiological study of the prevalence of caries, periodontal diseases and malocclusion in a school population].

A randomized stratified sample of children 3 to 12 years of age has been examined, DMFT, CPITN, soft deposits and malocclusion have been analyzed. The prevalence of caries, periodontal involvement and malocclusion has been observed to be rather high, thus requiring the organizing of detailed preventive programs to reach the W H O target set for the year 2000.

[Progression of DMF index--DMF from 3 to 12 years: need for preventive intervention].

To evaluate the prevalence of soft deposits and the trend of dmf/DMF index, a group of children between 3 and 12 years of age has been examined. A DMF Index of 5.74 at 12 proves the need to promote educational and prevention programmes in the Ulss 34 area since the WHO program "Health for all in the year 2000" sets a target of a DMF Index below 3 at 12.

[Water absorption and resistance to wear of 2 newly invented composite resins].

Two recently built composites, one for posterior teeth, and the other for general employ, were evaluated in relation to their water absorption and resistance to wear by means of the "scratch test". Critical loads and attrition of the two materials were also evaluated, with statistical analysis. The results supported the good qualities of the two composites, which are to be considered very advanced in the field of esthetic reconstruction materials.

["On line" processing using a microcomputer of bioelectric signals of gnathological significance].

EMG during diagnosis and treatment monitoring in orthodontics and gnatology has become widely used. The Authors describe the linking of a PC to an amplifier of EMG signals. The program is then reported and commented on.

[A proposed method for analysis of the correlation between electromyographic and cephalometric parameters].

This work reports on a method of analysis and statistical correlation of electromyographic and cephalometric parameters. Has been employed a computer as oscilloscop with digital memory.
