Outcomes of Nonsurgical Retreatment and Endodontic Surgery: A Systematic Review
Published in Niall MH McLeod, Peter A Brennan, 50 Landmark Papers every Oral & Maxillofacial Surgeon Should Know, 2020
A wide range of success rates for initial root canal treatment have been reported.1–4 Lack of healing is attributed to persistent intra-radicular infection residing in previously un-instrumented canals and dentinal tubules, or in the complex irregularities of the root canal system.5 The extra-radicular causes of endodontic failures include periapical actinomycosis,6 foreign body reaction caused by extruded endodontic material,7 accumulation of endogenous cholesterol crystals in the apical tissues,8 and an unresolved cystic lesion.9
An Introduction to Bioactivity via Restorative Dental Materials

Another field for bioactivity in endodontics is related to the use of antibacterial root canal sealers in the root canal treatment. Root canal treatment aims to eliminate the bacterial infection, disinfect the root canal system from the bacteria and their by-products, and reduce the risk of getting recurrent infections in the future. Despite the disinfection of the root canal system, the total elimination of residual bacteria is not guaranteed and is at risk of being re-infected (Saleh et al. 2004). Therefore, the use of antibacterial canal sealers may improve the success rate of endodontic treatment. Enterococcus faecalis is the main endodontic pathogen that is able to invade the dentinal tubules and survive by itself in the treated canals by resisting the endodontic treatment (Sundqvist et al. 1998). The main limitation of most of the available endodontic sealers is related to the loss of their antibacterial function gradually after the setting (AlShwaimi, Bogari et al. 2016).
Dentin-Pulp Complex Regeneration

There are no objective clinical parameters to determine how much carious dentin should be removed; the question arises as to whether to cap the exposed pulp or perform a root canal treatment directly. A systematic review reported success in different longitudinal studies when a complete root canal treatment is performed (Ng 2007). Tooth with pulp exposure subsequent to caries excavation, the cost-benefit relation between a capping procedure, and root canal treatment could still be balanced or even favor pulpectomy (Schwendicke and Stolpe 2014). Completed root formation is a prerequisite for pulpectomy after pulp exposure. As an alternative to pulpectomy, pulpotomy offered a viable alternative to root canal treatment for teeth with vital pulps in short terms (Simon et al. 2013).
Is tooth conservation possible in odontogenic sinusitis? Prospective evaluation of affected teeth condition-based protocol

If the pulp of the affected tooth is necrotic even after ESS, it carries a risk of re-infection and relapse of sinusitis [17,18], and therefore root canal treatment is needed to remove the source of infection. On the other hand, an increasing number of patients with a periapical lesion in ODS receive endodontic treatment [18]. In our study, more than 80% of the patients had previous dental treatment. Many conditions do not respond to canalization owing to errors in the treatment procedure or the presence of a persistent extra- or intraradicular infection. Furthermore, root canal treatment for the molars is more challenging than for other teeth because of the complex anatomical structure of the canals, which increases the risk of improper treatment [19]. For these reasons, even in patients with a previous root canal treatment, periapical lesion may remain, or a new root canal lesion can develop and lead to maxillary sinusitis.
Periapical status transitions in teeth with posts versus without posts: a retrospective longitudinal radiographic study

One possible limitation of this study is the retrospective design with a rather short follow-up time. The European Society of Endodontology suggests a clinical and radiographic follow-up after at least one year [18]. Failures developing after more than one year and so-called late failures are infrequent and only marginally affect overall evaluation of the periapical health in a group of teeth [20,21]. Others have concluded that 6–9 months evaluation appears to be an indicator for the final outcome of primary root canal treatment both in the presence and absence of initial apical periodontitis [22]. The minimum follow-up time in our study was 8 months from the definitive restorative treatment, which should be sufficient to register most apical changes associated with treatment procedures.
Effect of pain neuroscience education and transcutaneous electrical nerve stimulation on trigeminal postherpetic neuralgia. A case report

A 67-year-old woman sought physiotherapy service reporting pain, dysfunction, and sensory loss in the left jaw. The patient reported that the condition started 8 months before the first consultation as a sharp and throbbing headache on the left side, which forced her to interrupt her rest day from work. On the next day, the pain expanded to the lower teeth and the patient consulted a dentist, who diagnosed her with a periodontal problem. After four failed anesthesia procedures attempts, the dentist performed a root canal treatment without relief. On the following day, the patient noticed the presence of skin blisters on the left chin, with features of impetiginized lesions. A home-visiting physician diagnosed her with trigeminal PHN and prescribed oral Acyclovir, vitamin B, and Ibuprofen 4 times a day. After two days without improvement of the symptoms, the patient sought medical attention in a private hospital of Rosario (Argentina) where she was hospitalized for four days for medical examinations and treated with intravenous Acyclovir, Ciprofloxacin, Clindamycin, and Tramadol. After hospitalization, the patient continued taking Acyclovir 800 mg and Tramadol 25 mg orally 4 times daily for a month. After two months, she was instructed to stop the intake of Acyclovir and to continue the treatment with 40 drops of Tramadol daily. During the next month, the doctor allowed her to reduce the dose by one drop according to the severity of the symptoms. During these two months, the pain reached its higher intensity, and the patient spent most of her time in the bedroom.
