إن الهدف من هذا البحث هو تحري اختلاف الطريقة المستخدمة في تحضير الحفر السنية على قوة ارتباط ترميمات الراتنج المركب مع النسج السنية في الأسنان الخلفية. تألفت عينة البحث من ثمانين رحى قسمت عشوائياُ إلى مجموعتين رئيسيتين بحسب طريقة التحضير ( 40 رحى حضرت باستخدام السنابل الماسية, 40 حضرت باستخدام ليزر Er: YAG), خرشت جميع الأرحاء بحمض الفوسفور 37% لمدة 15 ثانية, غسلت بعدها بالماء لمدة 10 ثواني , جففت بتيار هوائي لطيف مدة 5 ثواني .
The of this study was to evaluate the bonding strength of a posterior composite restorations when two different types of equipment methods were used for preparation of dentin (Erbium-doped yttrium aluminum garnet laser (Er:YAG ) and diamond burs). This study specimen consisted of Eighty molars, was divided randomly into two main groups (40 molars were prepared with diamond burs, and 40 molars were prepared with laser Er: YAG).

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.
The aim of this study is to investigate the effect of early
coronal flaring on changing the working length of curved
canals by using NiTi rotary instruments and SS manual
instruments.
Forty five MB curved canals of upper/lower first and second
extracted molars were used.
The laser has been used as an alternative effective method of etching enamel surface for direct bonding of orthodontic brackets instead of phosphoric acid. The aim of this study was to compare shear bond strength of orthodontic brackets following Er-
YAG versus Nd-YAG Laser etching. Eighty human extracted upper premolars were collected and divided randomly into two equal groups; the buccal enamel surface of the first group was etched by Er-YAG laser while the second group was etched by Nd-YAG laser. Each group was divided into two equal subgroups according to the bonding material type (chemical cure resin or light cure resin). The mechanical test has occurred by using a universal testing machine (Instron). The finding showed that no statistically significant differences in mean of shear bond strength between (Nd-YAG, Er-YAG) Laser etching group were found regardless of the bonding type.
An appropriate bond between glass‑ionomer and the superficial
resin materials is very important for the success of sandwich
technique. The aim of the present in vitro study was to evaluate the
effect of three surface treatments of conventional glass‑ionomer on
its shear bond strength to giomer
The aim of this study is to evaluate the microleakage
resultant from; Silorane resin composite restorations in primary
teeth Prepared Using Burs And Er:YAG Laser with or without
using additional etching.
