Background: External inflammatory lateral resorption (EILR) following dental trauma is a severe complication that can lead to significant root loss and tooth extraction.
Objective: The aim of this project was to review current evidence in the literature on regenerative endodontic therapy (RET) for EILR following traumatic injuries and assess the best treatment practices.
Methods: Publications appearing in PubMed, from January 1, 2001 to January 9, 2022 were studied. Inclusion criteria were: (a) Publications in English; (b) Publications on RET and EILR; (c) Teeth subjected to dental trauma; and (d) Presence of intracanal bleeding and blood clots. Exclusion criteria were: (a) Conference proceedings; (b) Lectures; (c) Abstracts; and (d) Letters to editor; (e) Non-English publications.
Results: 355 publications were analysed. Nine met all inclusion criteria. In 10 (58.8%) teeth, triple antibiotic paste was used for an average of 26 days. Double antibiotic paste was used in 3 (17.6%) teeth for an average of 14 days. In 3 (17.6%) cases, calcium hydroxide (Ca(OH) ) was used for 14 days and negative pressure irrigation was applied once on 1 (6%) tooth.
Discussion: Using RET to treat EILR has some advantages compared to long term CA(OH) dressing. RET requires shorter dressing time compared to CA(OH) . This can significantly improve patient compliance. Additionally, in immature teeth, RET helps to arrest root resorption leading to continued root maturogenesis and revascularization. It is recommended that a meticulous follow-up should be conducted when RET is performed to assure early detection of treatment failure.
Conclusions: RET appears to be a good treatment modality producing biologic repair and improving prognosis in cases of EILR in post-traumatic tooth/pulp injuries. The key limitation of this study is that all publications included were either case reports or case series that usually tend to report successful outcome.

Introduction: The integration of artificial intelligence (AI) technologies in healthcare is revolutionizing the workflows of healthcare professionals, enabling faster and more accurate patient treatment. This study aims to evaluate the accuracy of responses provided by different AI chatbots to questions that dentists might ask regarding regenerative endodontic treatment (RET), a procedure that shows promising biological healing potential.
Methods: A total of 23 questions related to RET procedures were developed based on the American Association of Endodontists (AAE) 2022 guidelines.

Periodontitis, a widespread inflammatory disease, is the major cause of tooth loss in adults. While mechanical periodontal therapy benefits the periodontal disease treatment, adjunctive periodontal therapy is also necessary. Topically applied anti-inflammatory agents have gained considerable attention in periodontitis therapy.

Objectives: This randomized prospective controlled trial investigated the effectiveness of different strategies of regenerative endodontic therapy on necrotic mature anterior teeth with chronic periapical periodontitis with 18 months follow up.
Methods: A total analyzed 51 adult participant with mature single rooted teeth having necrotic pulp with chronic periapical periodontitis (PAI ≥ 3) were selected. Patients had been randomly categorized into three distinct groups (n = 17 each group).

Background And Aims: Chronic apical periodontitis (CAP), an inflammatory disease of the oral cavity caused by bacterial infections with Porphyromonas gingivalis (P. gingivalis) as a key pathogen, has been associated with systemic effects, potentially influencing distant organs including liver. The liver plays a key role in iron metabolism and immunity by hepcidin.
