هدفت هذه الدراسة إلى التقييم الشعاعي لفعالية الطعم الصنعي ™(Easy-Graft)المؤلف من [BCP+PLGA] في المحافظة على العظم السنخي بعد القلمع.تألفت العينة في هذه الدراسة من 30 حالة قلع أجريت عند 28 مريض (17 ذكور- 11 إناث), تم تقسيم العينة بطريقة عشوائية إلى مجموعتين:مجموعة الدراسة( 15 حالة) حيث تم تطبيق الطعم بعد القلع, والمجموعة الشاهدة ( 15 حالة) دون تطبيق طعم . تم إجراء صور ذروية من أجل المقارنة الشعاعية وذلك بعد القلع مباشرة وبعد 6 أشهر و 15 شهر من القلع لقياس مقدار النقص في ارتفاع السنخ. تم جمع البيانات باستخدام برنامج لتحليل الصور وتمت دراستها إحصائياً.وبنتيجة هذه الدراسة كان متوسط نقص ارتفاع السنخ في المجموعة الشاهدة(0.6 ملم) بعد القلع مباشرة و(2.4 ملم) بعد القلع ب 6 أشهر و( 3.3 ملم) بعد 15 شهر من القلع بينما كانت هذه القيمة الوسطية في مجموعة الطعم الصنعي(0.14,1.1,1.5 ملم) بعد القلع مباشرة وبعد 6 و15 شهر على الترتيب. وبالنتيجة كانت الفروق ذات دلالة إحصائية بين الأزمنة المختلفة لكل مجموعة على حدا كما كان الفرق جوهرياً بين المجموعتين..وهىكذا يمكن اعتبار الطعم الصنعي™(Easy-Graft) طريقة فعالة في الحفاظ على العظم السنخي بعد قلع الأسنان.
This study aimed to radiographically assess the effectiveness of the synthetic graft (Easy-Graft)™ which consists of [BCP+PLGA] in preservation of alveolar bone after teeth extraction. The sample consisted of thirty extraction cases in 28 patients (17males 11females) and was randomly divided into two groups; study group (15 cases) where the graft had been applied after extraction and the control group (15 cases). Periapical radiographs were taken immediately after extraction,and six and fifteen months later to measure the amount of bone height decrease. Data were collected by an image analysis software and statistically analyzed. As a result, the mean bone height decrease in the control group was (0.6mm) after extraction, (2.4mm) after six months, and (3.3mm) 15 months later.Whereas it was (0.14,1.1,1.5mm) after extraction, 6months and 15months later respectively. As such, there were statistically significant differences between the different follow-up times.Thus, (Easy-Graft)™ considered an effective method for alveolar bone preservation after teeth

socket preservation is a main therapeutic procedure to
prevent severe marginal bone resorption after tooth extraction.
Aim of this study: to investigate if there is any difference in the
amount of new bone formation 4 months after extraction and r
idge
preservation compared to that after 6 months, Using Coralline
hydroxyapatite as a bone substitute.
Assessment the changes in chin morphology after harvesting bone graft from
the symphysis using cephalometric radiographs.
This study was conducted to investigate the relationship between estrogen
depletion ,calcium-deficiency,and alveolar bone loss.
Alveolar bone loss was evaluated by radiographic and visual inspection of
rabbits with experimental lack of estrogen an
d calcium.
Twenty female local rabbits (4 months old) were divided into four groups
:group a -ovariectomized and given a standard solid diet.
Group b-ovariectomized and given a calcium – deficient diet
Group c-sham-ovariectomized and given a standard solid diet.
And group d-sham-ovariectomized and given a calcium-deficient diet
after 8 weeks,the rabbits were sacrificed .
The maxillae, mandibles, femurs, and tibias were removed carfully and
fixed in 10% neutral buffered formalin. The bone mineral density of each
bone and the alveolar bone loss were measured.the bone meniral densities of
the maxillae,mandibles,femurs and tabias in group (c) were significantly
higher than those in groups (b)and (d),but not higher than those in group
a.however there were no significant differences between any of the groups
with regard to alveolar bone loss from the cemento-enamel junction to the
molar bone crest.
The reconstruction of the nasal ala requires the achievement of esthetic and functional results. Composite auricular grafts are extremely valuable here. The purpose of this study is to evaluate the surgical outcome after using composite grafts for al
ar nasal reconstruction according to our experience. A retrospective study of our outcome of 10 performed alar nasal reconstruction cases. All these patients were operated using the proposed surgical technique between 2011 and 2015 in AL-ASSAD University Hospital in Lattakia, Syria. The cosmetic and functional results of this relatively simple technique of reconstruction are excellent. It provides an internal lining and support. The integration was total. We could fill the alar nasal defect using composite grafts. The defect has disappeared consequently. The form of the nose could be improved. The use of this technique efficiently enables a one-stage reconstruction of nasal defects. The morbidity rate within the donor areas was low. We believe that composite grafts have an important and under-utilized role as an adjunct to the flaps in nasal reconstruction.
Dental caries increasingly affects the children nowadays. Statistics
concerning caries prevalence aim to guide and improve the
prevention of dental caries.
Objective: The purpose of this study is to assess the prevalence of
dental caries in the posterior primary teeth depending on the
presence of decay, missing due to caries or filling.
