Three species of bacteria are most commonly implicated in the failure of endodontic treatment. The microorganisms colonize dentinal walls and any debris that is pushed through the apex as well as dentine tubules of pulpless necrotic teeth. Enterococcus faecalis Associated with 30-40% of failed root canal treatments May be resistant to calcium hydroxide as well […]
Root canal treatment failures can be attributed to two main causes: microbial or non-microbial. MICROBIAL causes can either be intra- or extra-radicular in nature Intraradicular Microorganisms found in root-canal-treated teeth with persisting periapical disease are different from those found in untreated teeth. The majority of bacteria found in treated teeth are Gram positive facultative anaerobes […]
The goal of vital pulp therapy is to preserve or regenerate tissues of the pulp-dentine complex of affected teeth and includes: direct and indirect pulp-capping, pulpotomy and more recently, regenerative pulp therapy. Pulp tissue may become compromised due to caries, loss of tooth structure/surface, traumatic injury or operatively as a result of cavity preparation. However, […]

What is the process of internal resorption and what is the necessary treatment? Internal resorption begins on the internal dentin surface and spreads laterally. It may or may not reach the external tooth surface. The process is often asymptomatic and becomes identifiable only after it has progressed enough to be seen radiographically. The cause is unknown. Trauma […]
