Positively charged imidazolium-based ionic liquid-protected silver nanoparticles: a promising disinfectant in root canal treatment

Infection caused by microorganisms play a crucial role in the induction of inflammation of pulpal as well as the periapical tissues. Factors like improper disinfection or obturation of the root canal space contributes to the failure of the root canal treatment. The aim of the study was to modify the contents of MTA-based sealer with nanoparticles and check for its antibacterial efficacy against E. faecalis. Silver nanoparticles (10 nm) were incorporated in MTA based sealer at various concentrations to form the test product. The antibacterial efficacy of the modified sealer was tested by well diffusion test on E. faecalis. The zone of inhibition (mm) was checked for each test product. Analysis of the results showed significant diameters of zones of inhibition (mm) as compared to sealer without nanoparticles. The zone of inhibition increased with the increase in the concentration of silver nanoparticles. The silver nanoparticle incorporated sealer can be used in the clinical setup to prevent reinfection of the root canal system and ensure the success of the root canal treatment.

Rotating Blade

The biological objectives of root canal treatment have not changed over the recentdecades, but the methods to attain these goals have been greatly modified. Theintroduction of NiTi rotary files represents a major leap in the development ofendodontic instruments, with a wide variety of sophisticated instruments presentlyavailable (1, 2).Whatever their modification or improvement, all of these instruments have onething in common: they consist of a metal core with some type of rotating blade thatmachines the canal with a circular motion using flutes to carry the dentin chips anddebris coronally. Consequently, all rotary NiTi files will machine the root canal to acylindrical bore with a circular cross-section if the clinician applies them in a strictboring manner

Abstract- - Microorganisms and their by-products are considered to be the major cause of pulp and peri-radicular pathologies, and for the dis-infection of these canals we need proper shaping, cleaning of these canals with mechanical instruments and chemical irrigants. Here we are discussing about the chlorohexidine with a concentration of 2% in root canal treatment. It has been found that there is a highly significant reduction in the number of microorganisms in the chlorhexidine-treated specimens after instrumentation and irrigation. Here we will discuss the merits and de-merits of chlorhexidine and its use in root canal as an irrigant or medicaments.

Fracture Level

A Patient came with the complaint of pain in the lower right back region of the jaw. Root canal treatment was planned. While preparing for the bio-mechanical procedure, the Hand pro taper fractured in the apical third. Iatrogenic occurred as a result of the fracture of the endodontic instrument. Retrieval of the fractured instrument was planned to complete the cleaning and shaping of the canal. The removal of the fractured instrument was planned to be done under the Dental Operating Microscope. The use of an operating microscope enhanced the illumination and the magnification of the instrument. This illumination and magnification helped in the precision of removal. The ultrasonic tip enabled to reach of the fractured instrument in the canal and loosen the dentin around the fractured instrument. It allowed easy retrieval of the fractured instrument. During the retrieval procedure, the fractured instrument was bypassed before the use of the ultrasonic tip. After the removal of the fractured instrument, cleaning and shaping were completed, followed by obturation, definitive restoration, and prosthesis. As the removal of the fractured instrument enabled complete cleaning and shaping, it improved the prognosis of the case. When the endodontic instrument gets fractured, it should be analyzed over the radiograph to assess the fracture level, the anatomy of the root canal, size of the fractured instrument, check accessibility, stage of fracture, etc. If all the above criteria are met with the removal of the instrument only then, replacement should be tried. Otherwise, it may lead to a severe loss of root dentin, decreasing fracture resistance of the root.

Culture of Staphylococcus aereus was taken from liquid BHI media, then rubbed on the entire surface of BHI media using a sterile cotton stick. The antibacterial zone formed is measured.</pre><pre> </pre><pre>Result : Based on the results of the Mann-Whitney test there were significant differences in the inhibitory power of Staphylococcus aureus bacteria (p <0.05) in the K + group with groups K-, P1, P2 and P3. Whereas between groups P1 with K-, group P2 with K- and P1, and group P3 with K-, P1 and P2 there were no significant differences because the significant value was greater than 0.05</pre><pre>Conclusion : There is no antimicrobial power at concentrations of 18%, 24%, and 30%.
