Aarti Bohora, Sharad Kokate
AIMS AND OBJECTIVES: The principal goal of endodontics is the prevention of periapical infection. Acute and chronic apical periodontitis occur due to the persistence of pathogenic microorganisms such as Enterococcus faecalis and Candida albicans harboring the root canal systems of the teeth. The concept of the use of probiotics in addressing endodontic disease is new and has not been studied adequately. On the basis of the success of probiotics in periodontal treatment, this preliminary work was performed (a) to evaluate the antibacterial efficacy of probiotics against common endodontic pathogens, i...

Jingjing Zhu, Xinhuan Wang, Yanjun Fang, Johannes W Von den Hoff, Liuyan Meng
Dens invaginatus is a malformation with varying anatomical features, posing challenges to treatment. Early and accurate diagnosis plays a significant role in selecting the appropriate treatment. The diagnosis of teeth with a complex root canal system including dens invaginatus has made progress with the application of three-dimensional imaging techniques in endodontics. Advanced treatment options provide hope for teeth that could not be saved before. This review discusses diagnostic methods and treatment options for teeth with dens invaginatus, and provides guidelines for the management of dens invaginatus cases in clinic...

Xi Wei, Bo Hu, Haiyang Peng, Ming Tang, Jinlin Song
As a dangerous factor in vertical root fracture, dentinal crack formation is often associated with root canal instruments. We conducted this meta-analysis to compare the influence of two types of nickel titanium (NiTi) instruments that have different movements (reciprocating single-file versus full-sequence rotary file systems) on dentinal cracks formation during root canal preparation. Searches were conducted in PubMed, ISI Web of Knowledge, Embase and Cochrane Library using a combination of keywords. Titles and abstracts of all articles were independently assessed by two reviewers in accordance with the predefined inclusion criteria...

Microorganisms should be considered to have the major role in starting and perpetuation of pulpo-periapical diseases. Using intracanal medicaments is necessary to gain a bacteria-free environment in the canal system. Calcium hydroxide (abbreviated as Ca(OH)2), which is the most commonly used medicament in endodontic therapy, has been shown to be effective against primary sources of infection; however, its effectiveness against some microorganisms, such as Candida albicans and Enterococcus faecalis has not been proved...
