Diagnosis A 12-year-old male in the late mixed dentition was referred by his dentist for orthodontic treatment. Initial examination revealed a skeletal and dental Class II malocclusion with a retrognathic mandible, a severe overbite, moderate overjet, and mild malalignment of both arches, including rotations and generalized spaces in the mandibular arch (Fig. 1). The facial type was hypodiverge...

Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of this study was to determine in which type of malocclusion the correlation between overjet and skeletal sagittal parameters assessed by lateral cephalogram analysis is the highest. The extent to which overjet can predict skeletal relationships in the sagittal plane was also assessed. Eight...

Abstract Introduction Extraoral strength is the most common strategy to correct Angle Class II malocclusion, restricting and redirecting maxillary growth. Objective To evaluate skeletal changes resulting from use of headgear, with cervical parietal anchorages, associated a full fixed orthodontic appliance, in growing patients malocclusion (Angle) treated clinic an training center. Material meth...

Abstract Cyanobacterial blooms have a significant impact on water quality. Implementing appropriate treatment methods to remove cyanobacterial secondary metabolites requires assessing their stability. In contrast cyanotoxins, the effect of abiotic factors cyanopeptides has been poorly studied. The present study analysed pH, temperature, visible and ultraviolet (UV) radiation stability chosen ol...

It is expected that commodity hardware is becoming less reliable because of the continuously decreasing feature sizes of integrated circuits. Nevertheless, more and more commodity hardware with insufficient error detection is used in critical applications. One possible solution is to detect hardware errors in software using arithmetic AN-codes. These codes detect hardware errors independent of ...
