The root canal system: a separate ecological niche?
Apical periodontitis is caused by microbial infection of the root canal system. Next generation sequencing on pulverized teeth was used to give insight into the complex microbial communities present in the intricate root canal system. Bacteriome profiling revealed an immense diversity. The most frequently identified genera were Prevotella, Lactobacillus, Actinomyces, Fusobacterium and Atopobium...
متن کاملA new system for classifying root and root canal morphology.
Knowledge of root and root canal morphology is a prerequisite for effective nonsurgical and surgical endodontic treatments. The external and internal morphological features of roots are variable and complex, and several classifications have been proposed to define the various types of canal configurations that occur commonly. More recently, improvements in nondestructive digital image systems, ...
متن کاملPreparation of the root canal system
The key factor in the development of pulpal inflammation and apical periodontitis is the presence of bacteria [42]. It has been widely accepted that bacteria and/or their products are the main aetiological factors in the initiation and progress of these diseases [10]. Consequently, the central focus of root canal treatment has been directed towards the elimination of bacteria and their substrat...
متن کاملRoot canal system of the maxillary canine.
To better assess the efficacy of mechanical preparation of root canals, transparent specimens of 250 extracted maxillary canines were investigated for canal configuration, thickness and curvature of the root canal, condition of any accessory canals, and location of the apical foramen. Fewer than 40% of the specimens showed accessory canals that were mechanically impossible to clean. The majorit...
متن کاملLearning the ecological niche.
A cornerstone of ecological theory is the ecological niche. Yet little is known about how individuals come to adopt it: whether it is innate or learned. Here, we report a cross-fostering experiment in the wild where we transferred eggs of blue tits, Cyanistes caeruleus, to nests of great tits, Parus major, and vice versa, to quantify the consequences of being reared in a different social contex...
