Prevalence of Bifid Mandibular Canals in a United States Dental School Population
… damage and bleeding concerns. “Bifid” mandibular canals are a normal anatomic variation of mandibular canals. The purpose of this study is to identify the prevalence of bifid canals, use the Naitoh classification system to classify the bifid canals, and to measure the height of alveolar bone above …

Modelling water and sediment chemistry in urban canals using chironomid pupal exuviae
… first was to classify chironomid assemblages in canals using pupal exuviae. The second was to understand the distribution of species, their ecology and function. The third was to find indicator taxa which were suitable to classify canals in terms of water and sediment chemistry. The fourth was to …

Comparative Efficacy of MUS System vs Er:YAG Laser System in Reducing Bacterial Biofilms in Root Canals
… to develop biofilms. Biofilm formation in the canals was sampled and confirmed with confocal laser microscopy. After incubation, the samples were randomly divided into four groups (n=10): Standard Needle Irrigation (SNI), MUS system, Er:YAG SWEEPS, and Er:YAG PIPS. The teeth were instrumented …

Incisal Endodontics Access vs Traditional Palatal Access to Negotiate Simulated Obliterated Canals Using Guided Endodontic Techniques
Introduction: Endodontic treatment in teeth with pulp canal obliteration (PCO) is challenging. Guided Endodontic Access (GEA) combines information from a cone-beam computed tomography (CBCT) scan with an intra-oral scan to create a stent that can be used as a guide to treat teeth with PCO. GEA …
