BACKGROUND: Regenerative endodontics (RET) refers to biologically based procedures that aim to restore damaged tooth structures and reinstate the pulp-dentine complex to its normal physiological state.
AIM: The purpose of this study was to examine the attitudes and practices of endodontists and paediatric dentists regarding RET.
DESIGN: A survey was conducted among endodontists and paediatric dentists from 13 countries. A number of factors were evaluated, including frequency of RET application, followed guidelines, disinfection techniques, intracanal medication type, scaffold type, preferred coronal seal material, and follow-up period.
RESULTS: Among the 1394 respondents, 853 (61.2%) and 541 (38.8%) were endodontists and paediatric dentists, respectively. Almost half (43%) of participants have not performed RET yet. The American Association of Endodontics guideline (47.3%) was selected as the primary source for the clinical protocol. The most frequently selected irrigant solution was 1.5%-3% NaOCl at the first (26.1%) and second (13.6%) sessions. A blood clot (68.7%) and MTA (61.9%) were the most frequently selected scaffold type and coronal barrier. Most participants preferred a 6-month follow-up period.
CONCLUSION: According to this survey, deviations exist from current RET guidelines regarding all aspects evaluated. Standardizing clinical protocols and adhering to available guidelines would help to ensure more predictable outcomes.

Introduction: A few studies investigated the numerous potential endodontic uses of CBCT, including the
examination of root canal morphology and presumed that CBCT was effective for the initial identification of
such morphology; moreover CBCT is a reliable method for the detection of the MB2 canal when compared
with the gold standard of physical sectioning of the specimen. The aim of this study was to identify the root
and canal morphology of the maxillary first molars among Malaysians analysed by cone-beam computed
tomography (CBCT) images.

Materials and Methods: Maxillary first (n = 421) molars from Malaysian patients
(n = 241) of Malay, Chinese and Indians inceptions were examined by two Endodontists using in vivo CBCT
methods. The number and configuration of roots, the number of root canals, and the canal configuration
according to Vertucci’s classification were determined.

Results: Single roots were not found in maxillary
first molars. The incidence of fused roots was 1.995% in the first molars between mesiobuccal and
distobuccal roots. In (421) 3-rooted maxillary first molars, additional canals were found in 45.6% of the
mesiobuccal (MB) roots and 0% of the distobuccal (DB) roots. Bilateral symmetry of the MB roots was found
in 82.36% of the first molar. Only one tooth was found to have pulp stone inside the pulp chamber.

Conclusions: The root and canal configuration of a Malaysian population showed different features from
those of other populations. CBCT scans can enhance the understanding of root canal anatomy, with the
potential of improving the outcome of endodontic treatment.

Fulltext Disappearance of Intracanal Medication: A Preliminary Clinical Finding from Retrospective Review of Teeth with Vertical Root Fracture

Ong TK

PMID: 33403352 DOI: 10.14744/eej.2017.17035

Objective: The purpose of this article was to report the finding of the disappearance of intracanal medication as a supporting evidence of vertical root fracture (VRF) through non-surgical intervention.
Methods: A retrospective review of the dental records of patients seen by an endodontist in a private endodontic office from September 2013 to September 2016 was conducted by the same endodontist. Cases that met the inclusion and exclusion criteria were assigned as the subjects of this study, and data were extracted from their clinical and radiographic records. Patient's demographic features, pre-operative signs and symptoms, details of rendered clinical procedures, follow-up visits, clinical and radiographic findings were recorded. Seventeen teeth for which non-surgical exploratory re-treatment was initiated were included in this study. Calcium hydroxide-based intracanal medication was placed for 2-4 weeks. Obturation of the root canals was performed if the tooth showed improvement of clinical signs and symptoms. If not, a cone-beam computed tomography (CBCT) scan was proposed to the patient to rule out VRF.
Results: After the non-surgical re-treatment was initiated, 13 teeth showed improvement of clinical symptoms and the re-treatment was therefore completed. The remaining 4 teeth presented with unresolved clinical presentations (deep pocket, presence of sinus tract and/or tender to percussion and palpation). Four teeth showed partial disappearance of intracanal medication where VRF was confirmed using CBCT in 3 teeth and with a conventional periapical (PA) radiograph in 1 tooth.
Conclusion: The disappearance of intracanal medication during non-surgical intervention was often associated with VRF. Thus, this feature may serve as an aid in diagnosing VRF.
