Background and Aim: ZOE has been used in different fields of dentistry for many years. A locally produced component (Zoliran) has been recently introduced to the marketwith similar characteristic to the original Zonalin. Because of a lower cost involved to use Zoliran cement and its availability, confirm reliability of its physical properties. This investigation was designed to assess the COMPRESSIVE strength of Zoliran cement in comparison to Zonalin cement as the standard material. Materials and Methods: Five samples with dimension of 4mmx6mm of each cement were provided and stored in distilled water in 370C±10C for a period of 24 hours. The lowest load of force was registered as the reference to which the sample could be broken by(according to the criteria No: 30 of ANSIIADA). The value of COMPRESSIVE strength was then calculated using the following formula (K =4F/πD2 ). Results: The mean COMPRESSIVE strength of five samples was measuredas: 14.33 Mpa for Zoliran cement and 31.83 Mpa for Zonalin cement. The mean COMPRESSIVE strength of Zonalincement was significantly higher than the mean suggested in ANSl/ADA Specification No.30. The mean COMPRESSIVEstrength of Zoliran cement was also lower than the mean value registered in ANSI/ADA SpecificationNo.30. Conclusion: COMPRESSIVE strength of Zoliran cement was significantlylower than that of Zonalin cement. Further tests are required to compare the other physical properties of this material before it can be clinically recommended.

Background: Different natural and synthetic materials were used for temporary burn wound coverage; however, they are associated with disadvantages including high price which prohibit their widespread use, especially in developing countries. Among all, human amniotic membrane is the only easily available and cost free coverage. Its effects on burn wounds have been studied in this survey.Methods: One-hundred and twenty four patients with 20-50% second and third degree burns and without any other disease were randomly assigned into two groups. The first 61 patients (control group) underwent traditional method of DRESSING with silver sulfadiazine and gauze which were changed twice a day. The remaining 63 patients underwent DRESSING with human amniotic membrane (amnion group), being changed every 3-4 days.Results: Patients in the control group had significantly lower albumin and needed more albumin infusion (231.80±234 gr. versus 111.51±143.82 gr.), received more blood transfusion (1.75± 2.52 bags versus 0.65± 1.18 bags), had significantly more intense pain and so received more narcotics than amnion group (7.97±12.85doses versus 3.84±7.56). Wound infection was higher in the control group (65.66% versus 46.91%) and so was the incidence of sepsis (24.62% versus 6.10%). There was 8.53% mortality in the control group versus 0% in the amnion group. All of the above-mentioned differences were statistically significant.Conclusions: Amniotic membrane DRESSING in deep and more extensive burns leads to better homeostatic, immunologic and local results and because of its low price, its use is strongly recommended.

Background: Active Leptospermum honey has non-peroxide antibacterial and anti-inflammatory effects, rendering it suitable for wound healing. Leptospermum honey is endemic in New Zealand belonging to the manuka bush (Leptospermum scoparium). The objective of the present research was to compare the efficacy of manuka honey DRESSING with conventional DRESSING regarding skin graft donor sites following a burn injury. Methods: This study was carried out in the department of surgery, Iran University of Medical Sciences, Tehran, Iran. It is a noncontrolled prospective trial, and an open-label study, analyzing Leptospermum honey and conventional DRESSING for the treatment of donor site areas for skin grafts. Data were collected from 15 eligible patients with burn wound. Two independent donor sites were formed, one of which was treated with active Leptospermum honey DRESSING and the other covered through the conventional method. Further collected was information regarding subjects’ demographics, self-reported pain (VAS scale), wound surface areas and bacterial wound culture. Results: In the treatment of skin graft donor sites, honey proved to be less painful compared with the conventional group (P=0. 001). Three and seven days following treatment, a significant decrease was observed in the mean wound surface areas in the honey group (P=0. 001). There was no significant difference between honey and conventional DRESSINGs with regards to the rate of infection (20% in honey DRESSING versus 40% in conventional group; P=0. 068). Conclusions: Active Leptospermum honey DRESSING accelerates the healing process, decreases pain and has antimicrobial activity and can be used for care of skin graft donor sites.
