الأهداف : يهدف البحث إلى دراسة تحليلية لشدة الضوء الصادرة من أجهزة المعالجة الضوئية (Light Cure) و المستخدمة من قبل أطباء الأسنان و لأنواع مختلفة.
المواد و طريقة العمل : أربعة أنواع من مصادر المعالجة الضوئية ULTRA-LITE (LED) Astralis 5 (Halogen), BlueLuxcer .TM (Halogen), Delma (LED), استخدمت لإجراء هذا التقييم، الشدة سجلت بواسطة جهاز قياس شدة الضوء من نوع (Cromatest-7041 / Mega-physics) عند مسافات مختلفة (16-0) ملم، و أزمان مختلفة 10، 20، 30 ثانية عند القدرة الواطئة و 5، 10، 20 عند القدرة العالية بين كل من رأس المعالجة الضوئية و جهاز قياس شدة الضوء.
النتائج : عند إجراء الاختبار على الأجهزة الثلاث الأولى فإن أكبر قيمة لشدة الإضاءة كانت بمقدار 562 mw / cm2 تم الحصول عليها من الجهاز BlueLuxcer .TM- high power) حيث كان رأس المعالج الضوئي بتماس (0 mm) مع جهاز قياس الشدة الضوئية و من ثم بمسافات 2, 4, 6, 8, 10, 12, 14, 16 mm و بزاوية (70°)، أما أقل قيمة تم الحصول عليها فهي من قبل جهاز ULTRA-LITE-LED و كانت 38 mw / cm2 عند نفس الزاوية و المسافات.
و لكن جهاز Delma-LED سجل أكبر قيمة لشدة الضوء بمقدار 772 mw / cm2 و أقل قيمة (268 mw / cm2) عند نفس مسافات القياس و لكن بزاوية 90°.

Abstract EN
The aim of this study was the analysis of intensity in different light cure units used in dentistry.
Materials and Methods: Four types of light curing sources units; ULTRA–LITE (LED) Astralis 5 (Halogen), BlueLuxcer.TM (Halogen), Delma (LED), were evaluated for the analysis.
Light intensity was recorded at various distances of 0 –16 mm, between the light curing tip and a curing radiometer, and at different times (10, 20, 30 seconds) in low–power and at 5, 10, 20 seconds in high–power.
Re-sults: The highest light intensity for the first three types (562 mW/cm2) was obtained by BlueLuxcer.TM – high power when the tip of light curing unit was in contact with a curing radiometer.
The light inten-sity for the three types of LCUs decreased significantly (p< 0.05) when the light tip was placed at an angle 700 and distance 0, 2, 4, 6, 8, 10, 12, 14, 16 mm away from the a curing radiometer, and the low-est intensity (38 mW/cm2) was obtained by ULTRA–LITE–LED.
But the maximum light intensity for the light cure type Delma–LED, was 772 mW/cm2 and the minimum was 268 mW/cm2 when the light tip was placed perpendicular 900 and distance 0, 2, 4, 6, 8, 10, 12, 14, 16 mm away from the a curing radiometer.
Furthermore, no significant differences (p>0.05) were detected between Intensity and vary-ing time at 5, 10, 20, 30 sec.
Conclusions: The intensity of the curing light was strongly affected by the angles and distance.
The decrease in light intensity was significant (p< 0.05) when the light tip placed at an angle 70° and a way to the aperture of the a curing radiometer, but the magnitude of the intensity it becomes more with the same procedure when the angle was perpendicular 900.
The decrease in the light intensity of the light curing units, agree with the inverse square law for the distances 0 to 16 mm.
The study found that there was no significant difference (p> 0.05) in light intensity between the light curing tip and a curing radiometer varying with time.
This study notice that the intensity of the light cure type LED is less than QTH(Quartz Tungsten Halogen).
