In the current investigation, we used direct and indirect methods to assess and treat several topographies of aggression that were hypothesized to have separate operant functions in a young boy with severe mental ratardation and pervasive developmental disorder. First, a functional analysis of aggression, using the methods described by Iwata, Dorsey, Slifer, Bauman, and Richman (1982/1994), was...

BACKGROUND The treatment of Class III malocclusion has been challenging for orthodontists.

OBJECTIVE The present study aims to investigate the current scientific evidence regarding the effectiveness of chin-cup therapy in Class III malocclusion of prognathic growing ...

Skin-derived precursor (SKP) cells are a valuable resource for tissue engineering and regenerative medicine, because they represent multipotent stem cells that differentiate into neural and mesodermal progenies. Previous studies suggest that the stem cell pool decreases with age. Here, we show that human multipotent SKP cells can be efficiently collected from adult cheek/chin skin, even in aged...

BACKGROUND Facial beauty depends on the form, proportion, and position of various units of the face. In terms of the frontal view and facial profile, the chin is the most prominent aesthetic element of the lower third of the face. Many methods have been implemented to obtain good proportions of the lower face. In this study, we applied the T-shaped genioplasty method to correcting chin deformit...

BACKGROUND The aim of the present study was to evaluate clinically and radiographically, the efficacy of immediate ridge augmentation to reconstruct the vertical and horizontal dimensions at extraction sites of periodontally hopeless tooth using an autogenous chin block graft. MATERIAL AND METHODS A total of 11 patients (7 male & 4 female) with localized advanced bone loss around single roote...
