Remineralizing Agents: A Comprehensive Review
Rakesh Mittal,Nikhil Relhan,Tanya Tangri 대한예방치과학회 2017 International Journal of Clinical Preventive Denti Vol.13 No.1
Remineralizing agents are the most desirable means of early enamel caries management. There is a scope for such agents as they prevent the progression of white spot lesions and reverse the process of demineralization. This need has redirected research to develop novel preventive agents that can act as an adjunct to fluoride or independent of it.
An Insight on Croll’s Microabrasion Protocol for the Correction of Enamel Discoloration Spots

Dental fluorosis is a major problem that presents clinically as whitish to yellowish-brown discoloration of teeth to varying degrees. It is a permanent defect that requires intervention by a dental clinician to restore the teeth to a more appealing appearance. One of the treatment modality for such defect is microabrasion, a procedure that is well documented and practiced since a long time.
Treating the Unexpected-Middle Mesial Canal: A Case Series
Prabhjot Singh Sodhi,Rakesh Mittal,Anshu Gupta,Devika Dhawan,Anchal Singla 대한예방치과학회 2013 International Journal of Clinical Preventive Denti Vol.9 No.4
The primary objective of endodontic therapy is to achieve a three-dimensional obturation of the root canal space after adequate preparation of the canal space to remove the tissue debris, microorganisms, and their byproducts. Anatomical variations have frequently been encountered in endodontic practice and have to be adequately managed by the clinician. Missed roots and canals are a major reason for failure of therapy. Technological advances have given the clinician ample opportunity to identify and treat these aberrations successfully. The present paper describes two cases of mandibular second permanent molar requiring root canal treatment, found to have three separate canals in the mesial root. These cases demonstrates a rare anatomical configuration and emphasizes the need for the clinician to be aware of and look out for such variations and use adequate diagnostic methodologies prior to and during therapy to detect such variations. The possibility of additional canals, whenever in doubt, should be explored with the assistance of technologies such as those of magnification and illumination and various diagnostic aids. Operator experience has also shown to be a key factor in negotiation and management of these aberrant canal configurations.

Amoebic liver abscess is a common disease, especially in endemic areas, but it is a rare cause of inferior vena cava (IVC) obstruction, with only a few cases appearing in the literature. We report three cases of amoebic liver abscess complicated with obstruction of the IVC and which responded to conservative treatment or radiological intervention.

<P><B>Abstract</B></P> <P>Plasmonic metal nanoparticles have been explored as a new class of chemical read-outs for assaying of a variety of chemical and biological species because of their unique physico-chemical and size dependent properties. Metal nanoparticles-based optical technologies are based on either new class of organic molecular assembly or with aggregation-induced optical changes features, which can also improve the sensitivity of drug assays in pharmaceutical analysis. This review describes the advantages of surface chemistry of plasmonic metal nanoparticles (e.g., silver, copper, gold, and platinum) for tuning of their colorimetric sensing applications in various drugs assays in pharmaceutical and biological samples. It provides insights of various plasmonic metal nanoparticles-based sensing strategies for the selective, sensitive and simultaneous colorimetric assay of drugs in pharmaceutical samples. Finally, we listed some research challenges to accelerate the development of plasmonic metal nanoparticles-based colorimetric sensors that are directly applicable for assaying drugs in pharmaceutical samples.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Surface chemistry of plasmonic metal NPs plays key role in sensing of drugs. </LI> <LI> Progress on plasmonic metal NPs for assaying of various drugs is reviewed. </LI> <LI> Plasmonic metal NPs act as magnificent visual readouts for simultaneous analysis of drugs. </LI> <LI> Analytical performances of plasmonic metal NPs sensors were tabulated. </LI> </UL> </P>
Post-cholecystectomy acute injury: What can go wrong?
Vikas Gupta,Ashish Gupta,Thakur Deen Yadav,Bhagwant Rai Mittal,Rakesh Kochhar 한국간담췌외과학회 2019 Annals of hepato-biliary-pancreatic surgery Vol.23 No.2
Backgrounds/Aims: Most of the emphasis of postcholecystectomy injuries is laid on iatrogenic bilary trauma. However, they can involve a wide spectrum of injuries. Methods: We prospectively evaluated 42 patients with postcholecystectomy injuries referred to us from July 2011 to December 2012. Based on spectrum of injuries, we proposed an algorithm of management. Results: Injuries occurred following laparoscopy in 20 (2 converted) patients and open in 22 patients. Mean time of detection of injury was 4.32±2.33 days. The nature of drainage was bilious in 36, bile with blood in 2, only blood in 2, and enteric in 2. Nine had organ failure at presentation. Six (14%) needed re-operation. Source of hemorrhage was from right hepatic artery in three and small bowel mesentry in 1. Enteric injuries were one each to duodenum and colon. Six patient (14%) died. Advancing age and organ failure were the predictors of mortality. Persistant biliary fistula was seen in 5 (14%). Ten had lateral leaks that closed at 28.89±2.34 days. Twenty-two formed stricture which was successfully managed with definitive hepaticojejunostomy. Conclusions: Post cholecystectomy acute injury does not limit itself to bile duct or vascular injury but it can traumatize adjacent hollow viscus or mesentery. It is important to diagnose and intervene enteric injury early. Presentation and management for such injury should be followed as per the proposed algorithm.
