Efficacy of chlorhexidine versus betadine as an irrigating agent during removal of bilateral impacted lower third molars

A prospective double blind study was carried out tocompare the efficacy of 0.02% chlorhexidine and 0.5% povidone iodine as an irrigating agent on control of pain and swelling following removal of bilaterally impacted lower third molars. Twenty patients with bilaterally impacted lower third molars, in similar positions were included in the present study. All the patients underwent surgical removal of the bilaterally impacted third molars in the same appointment. 0.02% chlorhexidine was used as an irrigating agent during the surgical procedure on a randomly selected one side [Group I] and 1% povidone iodine [Group II] was used on the other side [Group II]. Postoperative pain intensity was more pronounced in the Group II than in Group I [P < 0.05]. There were no significant differences in swelling between the two groups [P > 0.05]. Alveolar osteitis was noted in one case [5%] in Group II whereas it was nil in Group I. In conclusion, chlorhexidine was found more effective in control of postoperative pain and alveolar osteitis than povidone iodine when used for irrigation during the surgical removal of lower third molars. The control of swelling is similar in both the agents

Desmoplastic ameloblastoma: report of a unique case and review of literature.

Desmoplastic Ameloblastoma is a rare variant of ameloblastoma. 90 cases of desmoplastic ameloblastoma have been reported so far in literature. We are presenting a rare case of desmoplastic ameloblastoma in the ramus region of mandible with regards to its clinical and radiographical viewpoints. Only one other case of desmoplastic ameloblastoma has been reported in the ramus region of mandible of the 90 cases that we have reviewed. Review of literature has revealed the tumour to most commonly occur in the 3rd to 5th decade of life with a high preponderance of Japanese males. The anterior region of either jaw was most commonly found to be affected. Radiological appearance was most commonly of a mixed radio-lucent/radio-opaque type with a high incidence of poorly defined borders. However our case differed from the reviewed cases as it was found to be a unilocular lesion with well defined borders. Histopathological findings of our case were consistent with the hisotpathological appearance of the reviewed cases and showed extensive stromal desmoplasia and small tumour nests of odontogenic epithelium scattered in stroma.
