يعد الامتصاص الجذري من أكثر التأثيرات السلبية خلال المعالجات التقويمية و لاسيما عند تطبيق قوى الغرز، اعتمد تقدير الامتصاص الجذري الذروي في أغلب الدراسات على الصور الشعاعية الذروية و ذلك بمساعدة معادلات خاصة. لذلك كان هدف البحث هو دراسة مدى مصداقية الصور الذروية باستخدام معادلة Linge & Linge في تحديد مقدار تناقص طول الجذر السني خلال تطبيق قوى الغرز على القواطع العلوية و السفلية.
Apical root resorption is a common adverse effect during orthodontic treatment, specially the intrusion forces. Apical photographs by using the parallel technique and with the help of some formulas were the most common approaches to investigate the root resorption. The aim of this study was to study the reliability of periapical photographs in evaluating of root length shortening during orthodontic intrusion forces, by comparing with that diagnosed by using the CT-scan images.

Ultrasonic Tips is considered one of the common tool used in the management of separated instruments in the root canal, . , this research aimed to evaluate the temperature rise of the outer surface of the root when using ultrasonic tips to remove separated instruments from mesiobuccal canal of the lower molars.
IMF serves as a cornerstone during surgeries related to reconstruction orthognathic and facial trauma surgery. Successful treatment of mandibular fractures depends on reduction and restoration of normal occlusion and immobilization.
So this study
attempts to evaluate dental root damage through intermaxillary fixation with pre-drilled bone screws in the management of non-displacement or mini-displacement mandibular fractures. Complications were observed clinically and radiologically to evaluate the damage and loss vital to the adjacent tooth root. Data were subjected to statistical analysis using Chi Square Test. P-Value<0.05 was considered significant .This study found out that the intermaxillary fixation screws proved to be a safe technique to the intermaxillary fixation; however, it is not without complications or potential consequences which the surgeon must be aware of in order to provide safe and effective treatment.
Most work on scholarly document processing assumes that the information processed is trust-worthy and factually correct. However, this is not always the case. There are two core challenges, which should be addressed: 1) ensuring that scientific publi
cations are credible -- e.g. that claims are not made without supporting evidence, and that all relevant supporting evidence is provided; and 2) that scientific findings are not misrepresented, distorted or outright misreported when communicated by journalists or the general public. I will present some first steps towards addressing these problems and outline remaining challenges.
Our study focused on the relationship between root
Trunk length prevalence, Types of root trunk and furcation involvement in
molars.
Statistical results presented short root trunks in maxillary (1st &
2nd) molars were located buccally , whereas t
he long root trunks is located
mesially. Also for Mand. (1st & 2nd ) molar short root trunks were found
buccally but the long root trunks where found lingually and the lingual root
trunks were longer in mand, 2nd than mand 1st molars.
Aim: to compare NiTi hand instruments with Stainless- steel instruments according to separation, deformation and changing of working length during preparation of curved root canal in extracted teeth.
Materials and Methods: 24 of curved root canal we
re randomly divided into two groups. One group was prepared using stainless steel instruments and the other prepared by NiTi instruments. Separation and deformation of the two hand instrument systems were determined and the changing of working length during preparation were registered and compared. Data were collected and stastical analysis were conducted.
Results: Stainless steel system showed more separated and deformed instruments, but there were no significant differences between two systems. Also, change of working length was happened with stainless steel only but without significant differences with NiTi.
Conclusion: under the conditions of this study, it can be concluded that two hand instrumentation systems separated and deformed with no differences . However, working length was changed during use stainless steel but without differences between two system.
