This paper presents a case series of furcation involved teeth complicated with endodontic involvement which were treated with periodontal, endodontic and restorative procedures using different bone regenerative materials like; (a) Calcium phosphosilicate bone substitute having bioactive glass 69% mixed with glycerin 19% and poly-ethylene 12% dispensed in a putty form; (b) hydroxyapatite 70% and β-tricalcium phosphate 30% dispensed in granular form. All the cases were randomly selected having Grade II furcation defect with primary or secondary endodontic involvement. All cases were under observation for a period of 9 months. Measurements at 9 months post-surgery demonstrated that dental putty as bone graft substitute which was in combination of bioactive glass mixed with glycerine and polyethylene glycol showed better result as compared granular bone graft which was in combination of hydroxyapatite and β-tricalcium phosphate.

Department of Endodontics, Beijing Stomatological Hospital, Capital Medical University, Tian Tan Xi Li No.4, Beijing, 100050, China.
Background: To evaluate the prevalence and characteristics of taurodontism in northern China by using cone-beam computed tomography (CBCT) and assisting the treatment.
Methods: The study involved CBCT scans of 8112 teeth from 507 participants of northern China, comprising 217 males and 290 females aged 18 to 60. Analysis was conducted using Shifman and Chanannel's criteria to assess the prevalence and attributes of taurodontism, examining differences based on tooth position (maxilla and mandible) as well as gender (P < 0.
Removal of a fractured file beyond the apical foramen using robot-assisted endodontic microsurgery: a clinical report.
BMC Oral Health

Background: Endodontic file fractures are common complications of root canal treatment, and requires removal via specialized techniques such as endodontic microsurgery when the file beyond the apical foramen. It is often challenging to precisely and minimally remove a fractured file. Recently the use of dental autonomous robotic system (ATR) has shown promise in precisely and minimally in dental surgery.

Key Laboratory of Shaanxi Province for Craniofacial Precision Medicine Research, College of Stomatology, Xi'an Jiaotong University, Xi'an, Shaanxi, China.
This study aimed to investigate the involvement of macrophage ferroptosis in chronic apical periodontitis (CAP) and determine if blocking JNK/JUN/NCOA4 axis could alleviate CAP by regulating macrophage ferroptosis. Firstly, the models of apical periodontitis (AP) and models of CAP, including clinical specimens and rats' periapical lesions, were utilized to investigate the role of macrophage ferroptosis in CAP by detecting the ferroptosis related factors. The activation of the JNK/JUN/NCOA4 axis was observed in CAP models.

The successful management of necrotic pulps and apical periodontitis poses a tough challenge in endodontic therapy, as it involves addressing compromised tooth vitality and microbial invasion of root canal systems. Failure to effectively treat these conditions can lead to persistent infection and severe patient discomfort. The efficacy of double antibiotic paste (DAP), a mixture of ciprofloxacin and metronidazole, was evaluated and compared to calcium hydroxide (CH) by assessing radiographic and clinical outcomes of nonsurgical endodontic treatment in cases with necrotic pulps and the presence of apical periodontitis.
