Background: Organic tissue dissolution is considered as one of the most important and desirable property of endodontic irrigant, any soft tissue remnant, harboring bacteria, left in the canal after endodontic therapy may be the cause of failure. Aim: The present study aimed at assessing and comparing the human pulp dissolution (thereby eliminating the bacteria) capacity of some potential endodontic irrigants viz., sodium hypochlorite (NaOCl) (2.5% and 5.25%), chlorine dioxide (5%) and peracetic acid (5%). Materials and Methods: Forty human pulp specimens from extracted premolars were taken and weighed. They were immersed in test solution for 30 min, dried on filter paper and weighed again. The percentage weight loss was calculated and statistically analyzed. Conclusion: It can be concluded that NaOCl showed the best tissue dissolution capacity, followed by 5% peracetic acid.

AIM: To analyse the root canal morphology of mandibular third molars using clearing technique. MATERIAL AND METHODS: Ninety permanent extracted mandibular third molar teeth were collected based on inclusion and exclusion criteria. Teeth were then decalcified and were made transparent Methylene Blue Dye was injected to color the pulp space. These teeth were then observed under sterio Microscope and root canal systems were identified according to Vertucci's Classification. RESULTS: The most common anatomical morphology found was having two roots. Overall type I Vertucci’s configuration was the most common pattern of canals. Other canal patterns that were found included type II, III, IV and V. In this study no canal of type VI, VII or VIII were found. CONCLUSION: The morphological variations in root patterns and canal configuration of mandibular third molar should be given consideration for successful endodontic treatment.

Mandibular molars can have an additional root located lingually (the radix entomolaris) or buccally (the radix paramolaris). If present, an awareness and understanding of this unusual root and its root canal morphology can contribute to the successful outcome of root canal treatment. This paper describes case report of mandibular first molar with three roots (one mesial and two distal) and four canals (two in mesial and two in distal root). These case reports show an anatomic variation of internal morphology of the tooth and points out the importance of searching for additional canals.

Background and study aims: Hypertriglyceridemia can be a primary cause for acute pancreatitis or secondary to other factors prior to the increase of lipid levels, or both. The aim of our study was to assess the severity of acute pancreatitis with elevation in serum triglyceride levels and report the outcomes of our series. Patients and methods: One hundred twenty-six patients of acute pancreatitis were admitted within 72 hours of onset of symptoms, out of whom 26 patients were excluded during the course of study due to preexisting comorbidities. 100 patients in the study population were divided into group A having serum triglyceride levels ≥500 mg/dl (n = 30) and group B having <500 mg/dl (n = 70) at the time of admission. Results: The mean age of group A was similar to group B (50.2 ± 17.1 vs 49.26 ± 17.2 years; p = 0.860). Most common etiological factor of acute pancreatitis was found to be gall stones (56%) in both groups. Ranson's score at admission in group A was 2.93 ± 0.22 and in group B it was 1.34 ± 0.99. Mortality below two weeks was noted in (12/30, 40%) of group A and (6/70, 8%) of group B patients, which was statistically significant, (p = 0.015). Conclusions: The final conclusion of this study was that patients of acute pancreatitis with elevated triglyceride levels form a morbid group and these should be monitored aggressively for the development of any complications.
