Aim and Objectives:This in vitro study was designed to comparatively evaluate the antimicrobial efficacy of Curcuma longa (turmeric – T1-10%, T2-20%); Tachyspermum ammi (ajwain – A1-10%, A2-20%); chlorhexidine (CHX) gluconate gel (hexigel – 1%); and calcium hydroxide (10%) as intracanal medicaments against Enterococcus faecalis.Materials and Methods:Agar plates were prepared using brain-heart infusion (BHI) agar. Cultures of E. faecalis were grown in BHI broth at 37°C. Well diffusion method was used to derive results. Plates were inoculated for 72 h at 37°C and microbial zones of inhibition were recorded. Statistical analysis was performed with repeated measures analysis of variance.Results:C. longa (T2-20%) and CHX gluconate gel (hexigel – CHX-1%) showed larger zones of microbial inhibition than C. longa (T1-10%) that were statistically significant (P < 0.05) and were highly significant when compared to T. ammi (ajwain – A1 and A2) and calcium hydroxide.Conclusion:C. longa can be used as intracanal medicament in endodontic failure cases.
Background: Dacryocystorhinostomy (DCR) is a commonly done surgery performed for management of epiphora due to nasolacrimal duct obstruction. Goal of the procedure is to bypass the obstructed nasolacrimal duct allowing tear drainage into the nasal cavity directly from lacrimal sac by creating an anastomosis between the lacrimal sac and the nasal mucosa via a bony ostium. Common cause of DCR failure are attributed as an end effect of fibrous tissue growth, scarring and granulation tissue formation which obstructs the new drainage channel. Mitomycin c is an antiproliferative agent and may enhance the result of DCR by inhibiting fibrous tissue proliferation. Here we aim to evaluate the results of intraoperative mitomycin C application in dacryocystorhinostomy surgery compared with the result of conventional DCR. Methods: A prospective randomized comparative study of one year duration was done in the Department of Ophthalmology, Assam Medical College and Hospital, Dibrugarh, Assam, India. A total of 60 patients of acquired nasolacrimal duct obstruction were enrolled and divided randomly into two groups, 30 nos of patients in each group. One group had undergone conventional external DCR operation and other group was treated with DCR surgery with intraoperative mitomycin C application at the anastomotic flap and osteotomy site. Patients were reviewed after 1week, 1month, 3month and 6months postoperatively. The results of DCR surgeries were evaluated by observation of different parameters such as height of tear meniscus and patency of the nasolacrimal passage. Results: In our study we have observed that majority of cases were in 21-30 years age group with female preponderance (male vs female; 35% vs 75%). Chronic dacryocystitis was seen in majority of cases (70%) followed by mucocele (26.67%) and lacrimal fistula (3.33%). Major difficulties encountered during surgery and postoperatively were almost identical in both the groups. There was no case of abnormal mucosal bleeding, mucosal necrosis, delayed wound healing in patients which underwent DCR with mitomycin C use. Post-operative care and follow up were done identically in both the groups. It was seen that a total success rate of 80% was achieved in conventional group where as 96.67% success was achieved in MMC group at the end of 6 months. In case of scar prone conditions like lacrimal fistula mitomycin C use has shown to be efficacious in maintaining patency of the system after surgery. Conclusions: Distinctly higher success rate have been achieved in patients undergoing DCR with intra-operative MMC as compared to patients undergoing conventional DCR. Use of intraoperative mitomycin C can be considered safe and simple but very effective modification of conventional external DCR.
Aims: The aim of this study was to evaluate and compare canal transportation (CT), centering ability (CA), and volumetric changes in the curved canals prepared using Hyflex Electrical Discharge Machining (HEDM), ProTaper Gold (PG), and NeoEndo Flex rotary file systems through cone-beam computed tomography (CBCT). Materials and Method: Sixty mesiobuccal canals of maxillary molars were selected. Pre- and postinstrumentation CBCT scans were taken in the same position. CT and CA were calculated at 1 mm, 4 mm, and 7 mm from the apex; change in volume for the whole canal was measured and analyzed statistically. Results: The results showed that mean CT of HEDM and NeoEndo was less than PG at all levels, with significant differences at 4 mm and 7 mm. Regarding CA, no significant differences were found among the file systems. PG showed maximum volumetric increase with no statistically significant differences between the groups. Conclusion: All the experimental file systems respected the canal anatomy, although in the middle third, PG showed significantly more CT than HEDM and NeoEndo, whereas in the coronal third, PG showed significantly greater CT than NeoEndo. Regarding CA, no significant differences were found among the file systems. PG showed maximum volume of dentin removal.
Background: Schwannoma is a benign neoplasm originating from the neural sheath of peripheral soft tissues, but to occur within the jaw bones is exceptional. Plexiform schwannoma is a rare variant of Schwann cell tumour having plexiform pattern of intraneural growth with multinodularity. Case report: This report documents a case of a plexiform intraosseous schwannoma located in the mandible of a fifty‐four‐year old male. Conclusion: Although intraosseous schwannomas of the jaw bones and plexiform schwannomas of soft tissues of head and neck are documented in the recent literature; to the best of our knowledge, an intraosseous variant of plexiform schwannoma has not been reported.
