Management of Apical Periodontitis: Healing of Post-treatment Periapical Lesions Present 1 Year after Endodontic Treatment

Lower risk for cardiovascular mortality for patients with root filled teeth in a Finnish population

“…However, not all apical radiolucencies (typically assumed apical periodontitis) resolve post-treatment. In fact approximately 36% of post-treatment periapical radiolucencies remained unchanged in size or even increased after 12 months (Zhang et al 2015). The reason for this is because not all periapical radiolucencies are pathologic apical periodontitis: some are scar tissues and others can be cysts or tumours (Garcia et al 2007).…”

A prospective study assessing the effect of coronal tooth structure loss on the outcome of root canal retreatment

“…A combination of variables, such as undetected tooth cracks, difficulty to achieve ideal isolation, increased exposure time to oral bacteria and the difficulty in achieving a perfect coronal seal may affect more severely the outcome of root canal retreatment of teeth with increased loss of tooth structure. (Huumonen & Ørstavik 2013, Zhang et al 2015, Azim et al 2016. The recall rate in the current study was 88% for teeth and 86% for patients.…”

“…Several studies have shown that healing of apical periodontitis occurred in most cases during the first year (Huumonen & Ørstavik , Zhang et al . , Azim et al . ).…”

Evaluation of the endodontically-treated distolingual root of the mandibular first molar using cone-beam computed tomography

“…A root canal which was filled more than 2 mm short of the radiographic apex, whether containing voids or being extruded beyond the apical foramen, was considered as being an inadequate root filling. A periapical lesion was diagnosed as being present when disruption of the lamina dura was detected and the low-density area associated with the radiographic apex was at least twice the width of the periodontal ligament space [13,14].…”
