Aim:Based on the importance of coronal sealing right after endodontic treatment, this in vitro study aimed to evaluate the difference of shear bond strength to pulp chamber dentin treated with sodium thiosulfate and proanthocyanidin (PA).Materials and Methods:Fifteen extracted mandibular molar teeth were decoronated at the level of cementoenamel junction horizontally. The individual teeth were then sectioned mesiodistally to expose the pulp chamber dentin using a diamond disc. The specimens were randomly divided into three groups (n = 10). Group A: control group, treated with 5.25% sodium hypochlorite (NaOCl) for 30 min followed by a final rinse with 17% ethylenediaminetetraacetic acid (EDTA) solution for 3 min; Group B: after pretreatment with NaOCl and EDTA, it is further treated with 5% sodium thiosulfate (Na2S2O3) for 10 min; and Group C: after pretreatment with NaOCl and EDTA, it is further treated with 6.5% PA for 10 min. After drying the specimens, a bonding agent namely One Coat Bond SL (SwissTEC, Coltene) was applied to the pulp chamber dentin followed by a composite restoration (SwissTEC, Coltene). Each specimen was then tested under a universal testing machine at the dentin/resin interface to determine the shear bond strength.Results:Both the groups in which 5% Na2S2O3 and 6.5% PA were used for 10 min showed bond strength that was found to be statistically higher than the positive control (P < 0.05).Conclusion:The use of Na2S2O3 and PA can significantly increase the bond strength of composite resin to NaOCl/EDTA-treated dentin, allowing adhesive restorations to be immediately applied after endodontic treatment.

BACKGROUND: Surgical emphysema is well known and many case reports have been published on this. Many authors have reported this as a complication post dentoalveolar treatment. Diffusion of air into facial planes and periorbital area during endodontic procedures has been rarely reported. The use of three-way air syringe and forceful irrigation of root canal can lead to surgical emphysema of subcutaneous tissue planes in and around the teeth which are involved. CASE REPORT: This case report highlights one such complication seen during endodontic treatment and conservative management of this dental office emergency. CONCLUSION: Endodontic treatment is not frequently associated with the presence of the SCE. However, it is very important to know how to recognize this situation when occurs, to treat the patient appropriately.

AIM:This study aimed at assessing the trends of publications of Indian Endodontists in the field of rotary Endodontics in the PubMed database from 2000-2017.METHODS:The date of publication was set from 1st January 2000 to 31st December 2017, wherein keywords entered in the advanced search were “Indian” AND “Dental” AND “Rotary Endodontics”. From the collected articles the following criteria were noted: year of publication, the name of the journal, status of the journal, name of the first author, state of origin and the rotary Endodontic file system used.RESULTS:All data was subjected for statistical analysis by SPSS software version 16. The data were subjected to chi-square test, and a statistically significant difference (p < 0.001) was obtained in the inter-6 yearly interval starting from 2000-2017; in the status of the journal; the state of origin and in the generation of rotary files which were published during the study period.CONCLUSION:The plethora of publications by Indian Conservative Dentists and Endodontists is on the rise, and with the advent of better technology a greater interest in the mechanics and properties of these rotary file systems has invoked greater research work.

In this digital era consumers prefer online shopping to save time. But in their busy schedules it can be time-consuming to choose items as per their requirements. The area of our project is to create a user friendly and easily available application for purchasing mechanism. This application will be easily available on the internet for users to download it and then install it. To start, offer only the most popular grocery items, like milk and bread, and as the business expands, so can your product line. The operating format for the app would be very easy to establish. Customers would simply log on to the app, select the items they wish to purchase, enter payment and shipping information and wait for their groceries. We propose the solution using an application designed on Android Operating System platform. We choose this platform base since Google’s Android is one of the foremost reasons of this mobile revolution.
