Ameloblastoma is a type of Odontogenic tumor, commonly encountered in orofacial region. It is very aggressive in nature
with potential features of recurrence. Ki -67 is already a proven proliferative marker, which is used in our study to assess
the proliferative potentiality of Ameloblastoma. Incisional biopsy was done from 10 cases of Ameloblastoma and 5 normal cases as control, at the
department of Oral pathology and Microbiology, BIDSH, Patna. Each specimen was processed and two sections were prepared and stained with
hematoxylin and eosin and Ki-67 immunohistochemical marker. Positive stained cells with with Ki-67 in ameloblastoma along with normal
epithelium were counted from four randomly selected areas and were quantied using a microscope at 400x magnication. Positive correlation
seen with Ki-67 positive cells and percentages, which indicates the value of one variable increases, the other also increases. The overall conclusion
is that Ki-67 expression can be used as a prognostic marker in Ameloblastoma.
Aim:
To assess and compare the efficacy of dexamethasone ointment with triamcinolone acetonide, the gel form, in the treatment of minor recurrent aphthous stomatitis (RAS).
Materials and Methods:
This was a randomized clinical trial of 60 patients of either sex with clinically diagnosed RAS who were randomly divided into two groups—the dexamethasone ointment group (Group I) and the triamcinolone acetonide gel group (Group II). Patients were asked to apply the gel three times a day on each ulcer. Estimation of the efficacy of gel was done based on the time required for regression in pain, size, and number of ulcers.
Results:
The results showed there was a significant difference in size, pain, number, and duration of ulcers in Group I and Group II within 7 days. However, in both groups, no significant difference was noted in the treatment of RAS.
Conclusion:
Dexamethasone ointment was found to be efficient in this treatment and was safe as evaluated using clinical assessments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
