Comparative Evaluation Of Treatment Protocol Of Complex & Compound Odontoma A Retrospective Study.

Background & Objective: To document and discuss clinical features, evaluation for need of treatment of 30 radiographically and histopathologically proven cases of compound and complex odontomes of the jaw bones monitored and operated by single surgeon during 5 years. Methodology: A retrospective investigation of 30 cases of compound composite and complex composite odontomes was done. The study was performed using medical records, panoramic radiographs and pathological reports. Data gathered included age/gender, location, chief complaints, effect on dentition and treatment rendered. Results: 16 cases of compound odontoma detected in 1st & 2nd decades of life had 6 accidentally discovered on radiographs and 10 complaining of missing permanent teeth. 14 cases of complex odontoma discovered during 3rd -6th decades , 8 with complaint of the pain & paraesthesia of the affected region and 6 discovered accidentally on radiographs. None of the odontomes showed gender predilection. Considering the state of presentation, associated complaints and possible complications surgical treatment was done in symptomatic patients & asymptomatic patients were kept on follow up. Chi-square test performed was statistically insignificant (Chi Sq=0.089, df=1, p-Value >0.1). Conclusion: Odontoma, a benign odontogenic tumor usually has least propensity towards aggressiveness or malignant transformation. Treatment protocol of individual cases should be customized by considering the presenting complaints ,symptoms & natural progression of the concerned lesion. Considering the above factors, all cases of odontomes need not be surgically removed unless it grows to a potential large size causing gross facial deformities, pain & paraethesia of affected facial region or impaction of multiple permanent teeth.

Comparative evaluation of the antimicrobial activity of different endodontic sealers on enterococcus faecalis – an invitro study.

Background and objectives: To evaluate the in vitro antimicrobial activity of different root canal sealers. Materials and method: Five root canal sealers were selected for the study namely Zinc Oxide Eugenol, Endoflas FS, Endomethasone, AH plus and Sealapex . Enterococcus faecalis was obtained from American Type Culture Collection (ATCC 29212).The media used were Brain Heart Infusion Broth (BHI) and Blood Agar. 10 blood agar plates of 15 x 100 mm were prepared each inoculated with prepared E. faecalis to obtain Lawn culture. Ampicillin discs (10g) were used as the control discs. The sealers were manipulated under the UV laminar flow chamber. 100 microlitre (0.1 ml) of each sealer was placed on the sterile paper disc with micropipettes. The zones of inhibition were measured at 24 hours and 48 hours from the edge of the paper discs with help of vernier calipers and recorded. Results : Kruskal-wallis one way ANOVA was used to calculate the overall P-value. Mann – Whitney U-test was employed to identify the significant groups at 5% level after correcting the p-values for multiple comparisons by Bonferroni correction method. Conclusion: Endomethasone showed significantly greater antimicrobial effect against E. faecalis. There was no significant difference of antimicrobial activity between Zinc Oxide Eugenol and Endoflas FS on E. faecalis. Sealapex was less effective against E .feacalis. AH plus showed no antimicrobial activity on E. faecalis.
