ازداد استخدام الليزر و تطبيقاته في مجال طب الأسنان ازدياداً كبيراً في السنوات الأخيرة. يمكن للتخريش الليزري للميناء أن يقدم بديلاً للتخريش الحمضي المعتاد. إن هدف هذا البحث هو دراسة شكل سطح الميناء بواسطة المجهر الالكتروني الماسح بعد تعريضه لليزر، مع إضافة الحبر الأسود كمادة ممتصة للضوء أو من دونها، متبوعاً بالتخريش الحمضي أو غير متبوع. أنتج التخريش الليزري للميناء خشونة سطحية التي قد يكون ممكناً استخدامها لتثبيت الحشوات الراتنجية.
Laser use and applications in dentistry has increased dramatically in the last years. Laser etching of enamel may provide an alternative for conventional acid etching. The aim of this study was to evaluate, under Scanning Electron Microscope(SEM), enamel surface morphology after laser irradiation with or without the addition of photoabsorber (black ink); with or without acid etching. laser enamel etching produced surface roughness that might be used for the infiltration and subsequent mechanical retention of resin.

Propolis is used directly on dentin to reduce dental sensitivity following posterior composite restorations. The research aims to test its effect on the bonding of composite to dentin in posterior composite fillings by scanning electron microscopy. T
he depth of penetration of the composite resin within the dentinal canals was evaluated by comparing the frequency of the presence of resin protrusions and measuring Their lengths and the thickness of the hybrid layer were measured in the three sample groups.
This research is the first descriptive and classifiable study of the Syrian
spores of mosses in Syria and Arab world by using the technique of scanning
electron microscope.
Samples have been collected from several areas from Syria and their names
have been defined and classified earlier.
The study of nine Spieces of Spores have been completed and their shapes,
different faces and the shapes of redundant which they carry and their
distribution by scanning electron Microscope are done in Jena University,
Germany. Their sizes have been measured and viewed in several sizes.
It has been noticed clear differences in Spores, in the Shape of concavity of
the frost face and in existence and relation of denseness and distribution of
redundant on the faces. So, The characters of Spores can be added to other
standards which are used in Classification of mosses.
Almond seed wasp Eurytoma amygdali . End is a serious pest on
almond orchards which causes an economic losses in production.
This study was carried out for the morphological description of the
male stages of this pest (larva, pupa and adult) using
stereomicroscope and Scanning Electron Microscope.
The etching primary teeth dentin is more important factors for bonding
composit with primary teeth dentin.
objective: The aim of this research is to know the effect of time etching with the phosphoric acid 37% by
duration (7 or 15 seconds) for the composite bonding strength with primary molar dentin towards shear
strength.
Etching by phosphoric acid is considered an important factor to achieve
resin bonding to Primary enamel.
Bond strength was significantly higher in the third group (etching for
35sec) than the other groups (etching for (15), (25), or (45)sec).
The
re were no significant differences in bond strength between etch
durations: (15), (25), or (45) sec.
