An comparative evaluation of dentinal crack formation caused by three different nickel-titanium rotary file systems in primary anterior teeth.

Context: Cleaning and shaping of the canals damages the root dentin which becomes a gateway to dentinal cracks and thereby causes failure of the treatment.

Aim: The aim of this study was to assess and compare dentinal crack formation caused by three different nickel-titanium (NiTi) rotary file systems in primary anterior teeth.

Settings And Design: The present in vitro study is an experimental, comparative study.

Efficacy of Melaleuca alternifolia and chlorhexidine mouth rinses in reducing oral malodor and levels. A 1 week, randomized, double-blind, parallel study.

Objectives: The objective is to evaluate the association of Solobacterium moorei (S. moorei) to halitosis and to also check for the effects of two different mouth rinses on levels of S. moorei in saliva and tongue coating and its impact on oral halitosis.

Hysteretic Genetic Circuit for Detection of Proteasomal Degradation in Mammalian Cells.

Synthetic hysteretic mammalian gene circuits generating sustained cellular responses to transient perturbations provide important tools to investigate complex cellular behaviors and reprogram cells for a variety of applications, ranging from protein production to cell fate decisions. The design rules of synthetic gene circuits with controlled hysteretic behaviors, however, remain uncharacterized. To identify the criteria for achieving predictable control of hysteresis, we built a genetic circuit for detection of proteasomal degradation (Hys-Deg).
