Background: In children with Down syndrome (DS) the retarded growth potential cause a number of different clinical signs. Morphological deviations and an underdeveloped midface together with hypotonia contribute to increased prevalence of occlusal anomalies. Since the early 1980 ́s orofacial neuro-motor habilitation with palatal plates therapy have been used in Sweden. Aim: to investigate if use...

The aim of this study was to evaluate the ability to resist disinfection of a polymicrobial association contaminating the surface of dental impressions obtained with two different elastomers: a polyether (Impregum) and an addition-polymerized silicone (Elite). Impressions were contaminated with a mixture of three biofilm-forming microorganisms (Staphylococcus aureus, Pseudomonas aeruginosa and ...

Many commercial CD-ROMs are now being marketed as suitable for home and school use, increasingly promoted as covering the National Curriculum. However, such promises are failing to be realised because many CD-ROMS are poorly constructed, consisting simply of a mishmash of images, sounds and video that offer little more than light entertainment. The aim of this paper is to provide guidance on as...

introduction: complete adhesion of the impression materials to trays is important to prevent impression materials from being pulled away from trays during removed from the mouth and to ensure that the direction of polymerization shrinkage will be towards the tray. the aim of this study was to evaluate the effects of two retention features of custom trays (adhesive vs holes) on the dimensional a...
