ABSTRACT
Oral lichen planus is a common, chronic mucocutaneous condition of uncertain origin. Early treatment of OLP can dramatically reduce the risk of further development, which in turn reduces the risk of developing cancer. Numerous methods can be used to treat OLP. Since the significance of ozone in treating this disease is still uncertain. This systematic review was conducted based on english databases, including PUBMED, SCOPUS, Embase, Ovid, and Journal of Web up to July 2022. We used the search phrases "ozone," "ozone in the treatment of oral lichen planus," "oral lichen planus," and "ozone therapy." Finally, five papers were selected for qualitative analysis. This review included a total of five papers, four of which were clinical trials and one was a longitudinal study. All studies included the erosive form of OLP, also ozone therapy was applied to patients who did not respond to conventional treatment. Ozone showed significant therapeutic effects in terms of reduction in pain and size of the lesion. The signs and symptoms associated with OLP such as burning sensation, lesion size, and scarring all considerably improved with ozone therapy.
ABSTRACT
BACKGROUND: The purpose of this study was to evaluate the changed dimensions of dies obtained from impressions made with different combinations of addition sillicones which were subjected to variations in storage temperature. MATERIALS & METHODS: 45 die stone models were obtained of 45 impressions of which 15 each were stored at three different storage temperatures(25°C, 37°C and 42°C). 15 impressions each were made using one impression technique. The measurements of the dies made from the impressions were measured with the help of Profile Projector with a accuracy of 0.001mm. RESULTS: The results were statistically analyzed. The results indicated the significant decrease in dimensions when the storage temperature reduced from the mouth temperature. As compared to this there was a marginal increase in overall dimensions of all variables when storage temperature increased. CONCLUSION: More changes were seen in putty/light body combination followed by monophase and least in heavy/light body combination. How to cite the article: Kambhampati S, Subhash V, Vijay C, Das A.
