Association between mandibular asymmetry and occlusal asymmetry in young adult males with class III malocclusion.

Objective: Our aim was to assess the association between mandibular asymmetry and sagittal and transverse occlusal asymmetry in young adult males with class III malocclusion. Our hypotheses were that (1) mandibular asymmetry increases with increasing mandibular length and (2) occlusal asymmetry is correlated with mandibular asymmetry.

Material And Methods: On lateral cephalograms of 54 subjects, skeletal class and mandibular length were measured.

Different skeletal types underlying Class III malocclusion in a random population.

Introduction: We aimed to investigate the skeletal morphology underlying Class III malocclusion in a random population of young white men.

Methods: We randomly selected 3358 Swiss Army recruits and examined them clinically. Of 77 (2.

A nonradiographic approach to detect Class III skeletal discrepancies.

Introduction: Because of the hereditary nature of Class III malocclusion, relatives of affected subjects often ask for a consultation. To estimate the degree of skeletal manifestation without exposing them to radiation, an alternative to lateral cephalograms would be valuable for preliminary diagnosis. Thus, we aimed to assess the validity of profile photographs to detect skeletal Class III discrepancy.

Divergence in prevalence of mesiocclusion caused by different diagnostic criteria.

Introduction: The divergence in prevalence of a specific malocclusion is often striking. In addition to differences in ethnic background, sex, and age, inconsistency in diagnostic criteria might be important. Our aim was to investigate the prevalence of mesiocclusion in the same group by modifying the diagnostic criteria.

Kinetics of light-cure bracket bonding: power density vs exposure duration.

Introduction: Recent technologic advances make it possible to increase the light power density to reduce the necessary exposure duration. The kinetics of polymerization are complex. The special case of indirectly curing the thin layler of composite below the metallic bracket base further increases this complexity.

Bracket bond strength dependence on light power density.

Objectives: In order to reduce curing time for bracket bonding with light-cured composites, manufacturers increase the power density (PD) of light sources. The present study aims at investigating the relationship between PD and shear bond strength (SBS) at short exposure time.

Methods: Stainless steel brackets were bonded to bovine incisors using light-cured adhesive.

Light-curing time reduction with a new high-power halogen lamp.

Introduction: Orthodontic brackets are routinely bonded with light-cured adhesives. Conventional halogen lights used in bonding have the disadvantage of a long curing time, and the available alternatives (laser and plasma lights) are expensive. Our aim was to investigate the minimum time necessary to bond brackets with a new, relatively low-priced, high-power halogen light.

White spot lesions around brackets: in vitro detection by laser fluorescence.

Demineralization around orthodontic brackets is one of the side-effects of orthodontic treatment. However, simple methods for its early detection, quantification and monitoring are lacking. Therefore, the aim of this investigation was to evaluate red laser-light induced fluorescence for measurement of demineralization around brackets in vitro, and whether an interference by the brackets should be expected.
