The deprivation Some of the children to exercise some fine motor activities a big problem , as a consequence, this problem plays of the delay in motor development during early childhood , Usually it happens to be the reasons for the lack of the right place to play , and the lack of the presence of the tools needed to play motor, or fear excessive protection by parents for their children as a result of lack of awareness of the importance of physical activity for the child to use his fingertips and fine his muscles . In addition to that small percentage of children spend most of their time in the daily activities and skills of non-motor , Such aswatching television, or play video games or they tend to play computer and mobile but they are moving away from sound methods in their dependence on fine motor skills when using the fingertips of their hand.
The fine motor in kindergarten registration of such enormous developments in the control of the hands and fingers , This results in a lot of movements as in the ability to cut and paste and build homes using a small wooden or plastic pieces.
The child at this stage attracted to different of motor games so you must make way for him to satisfy the wishes and his penchant for movement by practicing popular games in physical education lesson , Which helps to identify the shapes, colors and sizes, as well as that to develop his physical attitudes towards self-understanding and controlling his movements and compatibility between the eye and the hand, And working with his hands and feet and speed of response to external stimuli for cognitive mental processes in general growth , And help it to grow, which links between cognitive learning and cognitive growth, which is a prerequisite in social life, especially in the advanced ages.
The current research aims to identify the fine motor skills of kindergarten children.
In the current research was to adopt the point of view of complementarity when building test by defining fields, which included four fields , namely (manual - manual synergies , the circular motion of the hand and wrist , grab finger index finger and thumb, visual - manual synergies ).
The researcher chose kindergarten (AL- Jamhoria), located in Morocco Street to apply tested on children preliminary stage whose age between (5-6) years totaling (190) boys and girls by (98) males and (92) females, divided into four divisions, so as to make the application Test them.
In addition, the researcher to extract validity discrimination and difficulty and consistency of the test parameters, so that it can be applied to the sample. Having been testing the sample application, the researcher enter data obtained from children's responses in statistical Pouch (SSPS), has revealed research that the sample suffer from weakness in the fine motor skills results, it has been interpreted researcher reasons for this weakness, according to this view integrative theories for the lack of attention to the motor side for these children since the early stages before entering kindergarten.
Background: Acrylic resin polymer s used in prosthodontic treatment as a denture base material for several decades. Separation and debonding of artificial teeth from denture bases present a laboratory and clinical problem affect patient and dentist. The aim of this study is to evaluate the effect of oxygen plasma and argon plasma treatment of acrylic teeth and thermocycling on bonding strength to hot cured acrylic resin denture base material. Materials and Methods: Sixty denture teeth (right maxillary central incisor) are selected. The denture teeth are waxed onto the beveled surface of rectangular wax block according to Japanese standard for artificial teeth. The control group consisted of 20 denture teeth specimen without any treatment.

Background: Prophylaxis methods are used to mechanically remove plaque and stain from tooth surfaces; such methods give rise to loss of superficial structure and roughen the surface of composites as a result of their abrasive action. This study was done to assess the effect of three polishing systems on surface texture of new anterior composites after storage in artificial saliva. Materials and methods: A total of 40 Giomer and Tetric®N-Ceram composite discs of 12 mm internal diameter and 3mm height were prepared using a specially designed cylindrical mold and were stored in artificial saliva for one month and then samples were divided into four groups according to surface treatment: Group A (control group):10 specimens received no surfa

Show MoreBackground: Periodontal diseases are bacterial infections of the gingiva, bone and attachment fibers that support the teeth and hold them in the jaw. α-amylase is an enzyme, produced mainly by parotid gland and it seems to play a role in maintaining mucosal immunity. Aims of the study: Determine the salivary levels of α-Amylase and flow rate and their correlations with clinical periodontal parameters(Plaque Index , Gingival Index , Bleeding on Probing , Probing Pocket Depth , and Clinical Attachment Level ) and the correlation between α-Amylase with flow rate of study groups that consist of ( patients had gingivitis and patients had chronic periodontitis with different severities(mild ,moderate ,severe) and control group .

The acrylic polymer composites in this study are made up of various weight ratios of cement or silica nanoparticles (1, 3, 5, and 10 wt%) using the casting method. The effects of doping ratio/type on mechanical, dielectric, thermal, and hydrophobic properties were investigated. Acrylic polymer composites containing 5 wt% cement or silica nanoparticles had the lowest abrasion wear rates and the highest shore-D hardness and impact strength. The increase in the inclusion of cement or silica nanoparticles enhanced surface roughness, water contact angle (WCA), and thermal insulation. Acrylic/cement composites demonstrated higher mechanical, electrical, and thermal insulation properties than acrylic/silica composites because of their lowe

Polyacrylamide Solutions of different concentrations (0.2, 0.4, 0.6, 0.8, 1.0 %) of Ag nanoparticles and ZnO nanoparticles were prepared, the viscosities and surface tension were measured for all solutions, where measurements indicated an increase in these properties with increased concentration, where the relative viscosity of polyacrylamide/zinc nanoparticles increased from 1.275 to 2.243, and the relative viscosity of polyacrylamide/silver nanoparticles increased from 1.178 to 1.934. Viscosity is significant parameters during electrospinning process. While the surface tension of the polyacrylamide/zinc nanoparticles has changed from 0.0343 Nm-1 to .0.0.0 Nm-1 and changed from .0.000Nm-1 to.0.0.0 Nm-1. Also the constants KH and KK were
