Abstract

Background: Cartilage forms most of the temporary skeleton of the embryo and provides a model in which most bones developObjective: Using laser therapy to enhance autologous cartilage grafts expansibility and to analyze whether this "enhancement" results in reduced rates of cartilage resorption and greater preservation of normal architectural features compared with "unenhanced" grafts. Type of the study: Cross sectional study.Methods: 24 New Zealand rabbits were divided into two groups (control and treated with 904nm, 10mW diode laser). Auricular cartilage segments measuring 1 cm2 were harvested from both ears of each rabbit, and were implanted in to the subcutaneous region of the left flank. 3 rabbits from each group were anaesthetized at 3, 6, 9 and 12 weeks post operation, implanted cartilages were then peeled. Gross and microscopic examinations were performed to assess size, structural integrity, and architectural features, with comparisons performed between each of the conditions. The results were assessed using T – test. Results: Grafts of control group were softer, more pliable when compared with grafts treated with laser irradiation. The rate of healing, and the quality of the cartilage is more enhanced in the treated group. The mean areas of the harvested cartilage grafts treated with laser therapy were 1.17 cm2 , 1.34 cm2, 1,64 cm2 and 1.76 cm2 respectively, while the corresponding value for the untreated specimens was 0.95 cm2, 0,99 cm2, 1.05 cm2 and 1.08 cm2. The percentage of decrease in size was 14% for the untreated specimens and 0% for the specimens treated with laser therapy for all cases. Conclusions: Our findings demonstrated significant improvements in graft quality using laser therapy. These findings may justify changes in how cartilage grafts are prepared and delivered for facial augmentation procedures to reduce graft resorption and maintain the structural integrity of the cartilage.

Abstract

The purpose of this study was to evaluate the clinical response to coralline calcium carbonate(CalCarb) bone replacement graft material in human infrabony periodontal pocket,and compares to open flap debridement . Twenty two patients completed the study with clinical data collected at baseline and after 6 months post-treatment. (14 males, 8 females; average age 42.77 ± 10.27, range 27 to 58 years) (11) patients received CalCarb grafts and(11) patients received open flap debridement(OFD) alone in randomly selected patient as part of their planned infrabony pocket defect correction surgery.Parameters measured in this study (clinical probing,depth, gingival recession, clinical attachment level). Statistical analysis for data with the use of a statistical software program at base line and after 6 months,the mean value of postsurgical pocket depth parameter for patients treated with CalCarb was highly significant difference higher than presurgical mean value for the same parameter,these results consist with other many studies (19-24) . For the mean values for the reduction of pocket depth(3.76±1.68) and gaining of clinical attachment level(3.5±0.71) were higher in patients treated with CalCarb , than those treated wih OFD nly[(3.3±0.79) (2.97±0.45) ] respectively.Natural coralline porous calcium carbonate appears to be a clinically useful graft material .

الهدف من هدة الدراسة هو لتقييم القياسات السريريةالناتجة عن استخدام الطعم العظمي(كورالين كالسيوم كاربونيت)المستخرج من نبات الشعب المرجانية البحرية استخدامة لعلاج ازدياد عمق الجيب اللثوي وذوبان العظم الموضعي و مقارنة هدة النتائج مع نفس القياسات ولكن باستخدام التجريف الجراحي.العينة تكونت من 22 شخص .التحليل الاحصائي للقراءة الاولى و القراءة الثانية بعد ستة اشهر اوضحت انتائج ان نقصان عمق الجيب اللثوي و احتساب مستوى الاربطة اكبر بكثير عند استخدام الطعم العظمي المرجاني مقارنة بالتجريف الجراحي .
