「Included were studies of patients with permanent immature or mature teeth and pulp necrosis with or without signs of apical periodontitis (P) comparing ETE (I) with calcium hydroxide apexification, apical plug and root canal treatment (C) in terms of tooth survival, pain, tenderness, swelling, need for medication (analgesics and antibiotics), radiographic evidence of reduction in apical lesion size, radiographic evidence of normal periodontal ligament space, function (fracture and restoration longevity), the need for further intervention, adverse effects (including exacerbation, restoration integrity, allergy and discolouration), oral health-related quality of life (OHRQoL), presence of sinus tract and response to sensibility testing (O).」

「Despite successful root canal treatment, if the majority of bone support has been lost from periodontitis, the tooth may have a poor prognosis.」

「Clinical Relevance: This study provides clinically relevant insight into multiple prognostic factors that influence the outcome of primary root canal treatment in teeth with periapical lesions, including patient-related, tooth-related, and procedural variables.」

「As predicted by model one, the probability of absence of periapical lesion 2 years after endodontic treatment was 90% in pulpitis teeth with sever root-canal curvature and adequate root canal fillings, but 51% in teeth with apical periodontitis.」

「Comprehensive case assessment, evaluation of all endodontic options, and risk assessment for caries and periodontal disease are always necessary when choosing the optimal treatment for a patient when initial root canal treatment has failed to heal.」

「The aim of this long-term cohort study was to evaluate the efficacy and complications of fixed partial dentures in a convenience sample of 100 patients with periodontal disease who were treated and maintained periodontal patients after 20 years.」

「Based on the study results we recommend using the hydrodynamic method of irrigation of root canals with 3% sodium hypochlorite solution in endodontic treatment of patients with chronic apical periodontitis. Цель исследования — оценить степень очистки дельтовидных ответвлений корневого канала в процессе эндодонтического лечения зубов. Выполнена морфологическая оценка состояния твердых тканей 14 удаленных зубов — резцов и премоляров — у пациентов в возрасте от 24 до 56 лет с диагнозом «хронический апикальный периодонтит». Выделены две экспериментальные группы: основная (1-я, 7 зубов) и контрольная (2-я, 7 зубов). Во 2-й группе проводили эндодонтическое лечение зубов с созданием модели клинических условий по традиционной методике c медикаментозной обработкой 3% раствором гипохлорита натрия и окончательным пломбированием гуттаперчевыми штифтами методом латеральной конденсации. В 1-й группе дополнительно применяли гидродинамический метод ирригации корневых каналов 3% раствором гипохлорита натрия с помощью аппарата RinsEndo. На основании полученных морфологических исследований рекомендуется использование гидродинамического метода ирригации корневых каналов зубов 3% раствором гипохлорита натрия с помощью аппарата RinsEndo дополнительно к традиционному эндодонтическому лечению пациентов с хроническими формами апикального периодонтита.」

「In certain clinical situations, root canal treatment in teeth with apical periodontitis is performed in multiple visits, with the use of intracanal dressing between visits, aiming to reduce microorganisms and their by-products of the root canal system prior to filling.」

「This study reported on the outcome of the nonsurgical root canal treatment/retreatment of teeth with large apical periodontitis lesions.」

「This study investigated the relationship between root canal treatment quality and the development and severity of periapical radiolucency in maxillary and mandibular molars using cone beam computed tomography (CBCT).」
