Elastin and collagen loss from the dermal layer is essential cause for wrinkles in
the face. Dermal fillers is the solution for this problem and this study compared clinical improvement
degree and the duration of correction between hyaluronic acid (Matrigel) versus bovine collagen (Zyplast)
for the correction of nasolabial fold.
This experiment investigates the effect of aluminum powder as metallic filler of
unsaturated thermosetting polyester resin on the wear rate and its mechanisms according to
time.
The obtained results show that the rate of wear increases with increa
se of time as a
result of increase the temperature generated of friction in all specimens. But when we add
the particles either Aluminum to polyester matrix, the rate of wear reduce as a result of
increase the thermal conductivity of polyester matrix, that leads reduction of the
temperature of contact surface, that leads less wear. We study the mechanisms of wear by
microscope of the worn surface. It found that the predominant mechanisms of wear vary
from adhesive wear at the lowest value of test time to abrasive wear (3- body) at the
highest value of test time.
The aim of this study was to evaluate the efficacy of botulinum toxin-A
(BTX-A) therapy compared with Transcutaneous Electric Nerve
Stimulation(TENS) in treatment against temporomandibular disorders
clinically study
Twenty patients with temporoma
ndibular disorder symptoms and signs
were enrolled in the study. The patients were randomly assigned into two
groups. Patients in group 1 were injected with 20 IU BTX-A in the
masseter and temporal muscle in both sides , whereas patients in group 2
were treated with (TENS),the electrodes were applied on masseter and
temporal muscle in both sides, time of stimulation abut 30s ,3perweek
for 4 week.
