This summary is based on information found in Disinfection of Root Canal Systems: The Treatment of Apical Periodontitis (Wiley Publishing, 2014) Six biological factors that lead to asymptomatic radiolucencies persisting after root canal treatment: Intraradicular infection persisting in the complex apical root canal system; Extraradicular infection, generally in the form of apical actinomycosis; Extruded root canal filling or other exogenous […]

Teeth undergoing orthodontic tooth movement may require endodontic treatment which could be related or unrelated to orthodontic treatment. However, it is always preferable to try to foresee and treat the tooth endodontically prior to beginning orthodontics for some of the following reasons: Pulpal or periradicular pain can be masked by discomfort associated with that of […]
Infections of an endodontic nature that are associated with orofacial pain are typically caused by obligate anaerobic bacteria. Given the spectrum of action, penicillins are the preferred antibiotic of choice. Drugs in this class act against the obligate anaerobes but, also affects the substrate interrelationships amongst various bacterial strains within the infection. As some of […]
While other materials are available for obturating root canals, gutta percha is still the most widely used and accepted material. Gutta perch is biocompatible, inert material which does not irritate tissues. Composed of zinc oxide, barium sulfate and transpolyisoprene, gutta percha has the ability to adapt to root canal walls. Resilon, a thermoplastic polymer which […]

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 […]
