يهدف هذا البحث إلى اختصار فترة المعالجة التقويمية إلى نصف المدة الزمنية على الأقل للتقليل من شكوى المرضى حول طول فترة العلاج التقويمي عبر تحريض إفراز البروستاغلاندين E2 بشكل موضعي عن طريق إثارة للعملية الالتهابية عبر حقن مواد متقبلة حيويا و مستخدمة بشكل روتيني في الممارسات السنية اليومية ليدوكائين 2% و الذي يؤدي إلى زيادة نسبة كاسرات العظم و حدوث امتصاص عظمي في المنطقة المحقونة ( منطقة السن المراد تحريكه ) .
This study aims to shorten the orthodontic treatment period into,at least, half the length of time. It takes in order to reduce the complaints of patients of the length of orthodontic treatment through the induction of the secretion of prostaglandin E2 topically by raising the inflammatory process via injection of vitally accepted materials which are used routinely in daily dental practice, Lidocaine 2% which leads to the increase of proportion of osteoclasts and the occurrence of bone absorption in the injected area ( the area of the tooth to be moved) .

Objective: to evaluate the effect of orthodontic treatment with fixed
appliances on periodontal tissues and to follow up the status of gingiva during 12 months of the fixed orthodontic treatment.
sample consisted of 30 patients undergoing orthodont
ic treatment with fixed appliances.
This study showed a clear increase in the values of the indices through time.
This study aimed to evaluate the effect of low-level laser therapy
(LLLT) on orthodontic treatment time reduction throughout leveling
and alignment stage.
We can conclude depending on this study results that LLLT is an
effective method for orthodontic archwire change acceleration and
consequently for reducing the orthodontic treatment time.
In very low concentrations, Prostaglandin E2 affects the electrical and contractile
activity of the smooth muscles of the gastric antrum, and this leads to a decrease
in the potential polarization of the membrane, and the appearance of muscle
cont
ractions. Both calcium and sodium ions play an important role in the
mechanism of the effect of prostaglandin E2 on this activity.
The smooth muscles of gastric fundus do not show any spontaneous activity.
Experiments have shown that prostaglandin E2 leads to the inhibition of the
contraction produced by stimulation, but has the opposite effect on the gastric
antrum. Calcium ions play an important role in this activity.
There is an increasing role for orthodontic mini implants as an anchorage device in orthodontic practice In many occasions, orthodontists may have to reuse orthodontic mini-implants (re-implanting again ) after sterilizing them by moist heat. The aim
of this research was investigating the effect of re-implantation and moist heat sterilization on the primary fixity of orthodontic mini-implants> Two lengths of mini-implants (6-7mm) (ti – 6A1 – 4A1 ) and two shapes (normal and dual thread ) were used and inserted in artificial bone (saw bone ) a first time and after sterilizing them by moist heat (Autoclave) a second time , in an insertion angle of 90 . The insertion and removal torque and periotest score (periodontium test device ) were measured to assess the primary fixity ( after implanting in the first time and the second time ) The results showed a decrease in the primary fixity after re-implanting and sterilizing by moist heat , but it still enough for using it a second time effectively to provide needed orthodontic anchorage for both two lengths and two shapes.
This study aimed to compare the effects of different enamel
etching techniques for bracket bonding strength. The sample
consisted of eighty human premolars were randomly divided into
four equal groups. The enamel surfaces of the teeth were etched
with 35% orthophosphoric acid in Group 1 , air abraded with
50 μm aluminum oxide prior to acid etching in Group 2, Trans
bond Plus Self-etching Primer (TPSEP) in Group 3 , Er: YAG
laser in Group 4. After enamel etching procedures, brackets were
bonded with Trans bond XT , then shear bonding test was
performed using a testing machine (Tinius Olsen).
