Aim: The aim of this systematic review is to accumulate the available evidence on management approaches as well as factors resulting in the development of paresthesia due to sealer extrusion.
Materials And Methods: A literature search was conducted in MEDLINE, EMBASE, and Web of Science and Cochrane Central Register of Controlled Trials up to March 2022, accompanied by a manual search of journals, textbooks, and grey literature. Inclusion criteria were studies on adult patients experiencing paresthesia related to sealer extrusion. The quality of included studies was appraised using a custom set of criteria.
Results: A total of 102 publications were identified, and 9 of them fulfilled the inclusion criteria. All of the included studies were case reports describing a total of 10 patients. The predetermined data were independently extracted and evaluated by four reviewers.
Conclusion: Because of the low amount and quality of available evidence, conclusions on the factors resulting in paresthesia due to sealer extrusion cannot be drawn. The management approach remains empirical. The need for prospective studies is highlighted. The future case reports in endodontics ought to be reported in a uniform and methodological way.
Clinical Significance: Paresthesia as a result of endodontic sealer extrusion is an alarming complication of endodontic treatment that general dentists need to be aware of. Although worrying, for both clinician and patient, it is a manageable complication and early diagnosis is important; thus, dentists need to be educated on this topic.

Quantitative Assessment of Apically Extruded Debris During Retreatment Procedures Using Three Nickel-Titanium Rotary Systems: An In Vitro Comparative Study.

: Apical extrusion of debris can affect the success of endodontic treatments, and the specific performance of certain retreatment systems has not been studied yet. Therefore, the aim of this in vitro study was to quantitatively assess the amount of apically extruded debris produced during retreatment procedures using three rotary NiTi retreatment systems in mature non-resorbed straight roots. : Thirty extracted permanent human teeth with single straight roots were selected.

Objective: To evaluate the outcome of teeth filled with a single cone technique and a premixed bioceramic sealer at 3 years of follow-up.
Methods: Healthy patients were consecutively treated by a cohort of postgraduate operators. Root canal filling procedures were performed with NiTi rotary instrumentation, while non-surgical retreatments were performed using NiTi reciprocating instruments.

Aim: This randomized clinical trial assessed the outcomes of nonsurgical root canal treatment (RCT), comparing a calcium silicate-based sealer (CSBS) with the single-cone technique (SC) with a zinc oxide-eugenol (ZOE) sealer and warm vertical compaction (WVC).
Methodology: Ninety-two single- and multi-rooted teeth were divided into two groups and treated using either the SC with BioRoot™ RCS (BIO) or WVC with Pulp Canal Sealer™ EWT (PCS). Teeth with apical periodontitis (AP) in both groups were further divided into BIOAP and PCSAP subgroups.

Article Synopsis
- This clinical study compares postoperative pain levels in patients who underwent single-visit root canal treatments using two different sealers (AH Plus and Endosequence BC) with or without sonic activation.
- A total of 72 participants were assessed for their pain intensity after the procedure and tracked their analgesic usage over the week following treatment.
- Results showed no significant differences in pain scores or medication intake between the two sealers or between the groups that had sonic activation versus those that did not.

Department of Operative Dentistry and Endodontics, Faculty of Dentistry, Mahidol University, Bangkok, Thailand.
Aim: The objectives of this study were to compare the clinical outcomes of root canal treatment between calcium silicate-based sealer using the cold hydraulic condensation technique and epoxy resin-based sealer using warm vertical compaction and to identify the prognostic factors affecting the outcomes of both obturation techniques.
Methodology: Dental records and radiographs of the teeth that received root canal treatment with calcium silicate-based sealer using the cold hydraulic condensation technique or epoxy resin-based sealer using warm vertical compaction during 2015-2021 were selected using inclusion and exclusion criteria. The cases were matched between the two groups based on four factors: primary root canal treatment or retreatment, tooth type, periapical lesion and its size and extension of root canal filling.
