Aim:The aim and purpose of this study was to determine the occlusal fracture resistance of three core buildup materials using the Nayyar technique.Materials and Methods:Thirty human extracted maxillary premolars were used for the study. The test samples were decoronated till the cementoenamel junction (CEJ) and proper cleaning and shaping was done with protaper niti files till the F3. Corresponding f3 protaper(Dentysply)gutta pecha cones were selected and obturated. The gutta-percha was removed till the depth of 4 mm from the coronal orifice with Gates Glidden (GG) drills for all the samples; then the samples were randomly divided into three different groups. Group I was restored with universal composite Z350XT, group II was restored with light curable glass ionomer cement (GIC), and group III was restored with miracle mix. The coronal buildup was done using compound supported matrix. The fracture resistance strength of all the specimen groups was tested under a universal testing machine.Results:The data of the study were statistically analyzed by one-way analysis of variance (ANOVA) and Bonferroni's comparison test. Results of the study showed that group I that was restored with the universal composite Z350XT showed much higher fracture resistance strength compared to the other two groups. Statistically significant difference was noted between group I and group II and also between group I and group III.Conclusion:It can be concluded that the core buildup done with composite offered better occlusal fracture resistance strength compared to light curable GIC and miracle mix.

Background:Isolated tibial shaft (ITS) fracture with intact fibula is a common injury but records often fail to mention it. Our primary aim was to study the effect of the intact fibula in ITS fractures in closed and open injuries and that these fractures can unite without a primary fibulectomy.Materials and Methods:56 patients who sustained an ITS fracture with an intact fibula who underwent closed or open reduction and reamed intramedullary interlocking nailing (IM IL nail) for closed and open fractures between August 2008 and April 2014 were included in this study. Four patients were lost to followup. One patient died due to causes not related to the surgery. At the time of final followup, 51 patients with 51 ITS fractures were available for the analysis. There were 33 closed and 18 open fractures. Patients were followed up at 4 weekly intervals until radiological signs of union were noted. They were assessed for functional outcome using the IOWA knee and ankle score systems at the time of final followup.Results:The average time to union was 19.7 weeks. Closed fractures united in 17.7 weeks as compared to 23.5 weeks for open fractures (P < 0.05). A delay in union occurred in 6 patients (4 open) and in 3 patients fractures failed to unite (2 open). The functional outcome as per the knee score and ankle score evaluation system was 93.13 and 92.54, respectively. The knee scores were 93.81 and 91.8 for closed and open ITS fractures, respectively (P > 0.05). Similarly, the ankle scores were 94.96 and 88.1 for closed and open ITS fractures, respectively (P < 0.05).Conclusion:ITS fracture with intact fibula is a common occurrence, and they can be treated safely with reamed IM nailing that provides good union rates and the excellent functional result even in open fractures.

BACKGROUNDAppendicectomy is the most common surgery done by a trainee general surgeon. Recent advances like laparoscopic appendicectomy is growing nowadays. We wanted to compare the parameters like operating time, post-operative pain and number of days it takes to come to back to work in patients who underwent laparoscopic and open appendicectomy and give significance of laparoscopic appendicectomy over open appendicectomy.METHODS 120 patients aged between 13 to 60 years of age were studied prospectively under two groups; 60 cases under laparoscopic appendicectomy group and open appendicectomy group. Age distribution, sex distribution, operation time, conversion rate and post-operative pain, intraoperative and post-operative complications, post hospital stay and days to return to normal activity are studied and compared. RESULTSMean operation time between the two groups is not significantly different between the two groups. Conversion rate was 3.3% for laparoscopic appendicectomy. Postoperative pain, duration of hospital stay and return to normal activity are significantly less in laparoscopic appendicectomy. CONCLUSIONSLaparoscopic appendicectomy is more advantageous to patients in terms duration of hospital stay and less post-op pain and requires less time to return to normal daily activity compared to open appendicectomy. But the learning curve for laparoscopy is the difficult part to the surgeon. HOW TO CITE THIS ARTICLE:Prakash GV, Sarada B, Chandra P, et al.
