Aim of study:
This clinical study evaluated the efficacy of Propolis (gel 50%) to
enhance the wounds healing after tooth extraction according of healing index.
The aim of this study is to evaluate the healing after
apicectomy by using two different techniques. And to evaluate the
effect of MTA as a retrograde filling material and also the Er:YAG
laser as a tool for resecting the apex, and the influence of them in
the healing.
The aim of this study was to compare the effects of
gingivectomy by using traditional surgery procedure and Er:YaG
laser depending on the following clinical indications: the pain
after 2 hours and 24 hours of surgery procedure, healing of
gum aft
er surgery depending on rosiness and polypus
indications after removing periodontal dressing and gingival
bleeding during and after surgery.
Bone healing is a complicated biological mechanism that is affected by many hormonal, nutritional, and hemal factors. The term Biomechanical theory of bone healing is a concept that is created by us and is used for the first time to identify and stud
y the influence of mechanical rules on the bone tissue so we can study and imitate its mechanical response depending on the rules of balance and movement. We ensure that bone healing is just adaptation to auto bone forming mechanism in the surrounding mechanical site. The term is more comprehensive and accurate than the bio-compression term which was used before; and all of those are confirming the criteria to evaluate the efficacy of fixators used in orthopedic surgery.
Amelogenins from ameloblast play an important rule in differntiating
odontoblasts in dental papilla, suggesting that amelogenins may associate with odontoblasts changes
during development.
Aim In the present study we have investigated the effects
of enamel matrix derivative (EMD) on the
healing of pulpal wound and formation of reperative dentin.
An attempt was made to have a better understanding of wond healing in
skin of adult white swiss mice. The process of healing showed microscopic
changes confirmed epidermal and dermal regions. The rate of change was
rapid up to ٤٨ hours. the epithl
ium invaded actively underlying connective
tissue but still detec-table whenever vascularity in the wound had subsided to
the dermis. By the time of epidermal cell-ularity, there was a closely packed
mass of cells immediately subjacent to the epithelium, which mostly represents
predominant cell types of in the subepidermal region. Our prognostic showed
that connective tissue accompanied by many dilated capillaries. There was also
an appearance of collagen fibers laying between the cells. The epithelium
followes the boundary of living connective tissue and comes into contact with
the dermal cells. Close contact between dermal and epidermal cells happened at
the time when epithelial invasion ceased and the basement membrane was
reformed close to the epithelium.
