J Endod 2024:S0099-2399(24)00340-6. [PMID: 38906528 DOI: 10.1016/j.joen.2024.05.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Accepted: 05/23/2024] [Indexed: 06/23/2024]
Abstract
INTRODUCTION The AAE Regenerative Endodontics Committee (REC) reports here the web-based survey data of regenerative endodontic procedures (REP) performed by the AAE members from 2008 to 2019. METHODS The web-based survey consisted of 2 questionnaires, a revascularization and a follow-up, including clinical and radiographic data at 3, 6,12 or >12 months after treatment. Data from demographics, etiology, clinical protocols, radiographic and clinical outcome as perceived by the clinicians were recorded. From 927 entries, 184 full cases were submitted and 126 were suitable for radiographic analysis. The data were divided into cases with 6-12 months and cases with > 12 months recall time. Descriptive statistics and univariate analyses were performed. RESULTS Predominantly patients were male (63%), average 10 years-old with anterior teeth (77.2%) due to trauma (69,6%). A wide variation in REP protocols were reported by AAE members. The most common clinical protocols used minimal instrumentation (75.5%), 2.5% or higher concentrations of sodium hypochlorite (83.7%), and antibiotic paste as intracanal medication (58.7%). The majority reported blood clot formation (56%) and most common coronal capping material was white MTA (50.5%). Increases in radiographic root length and radiographic root area were proportional to the time lapsed after treatment. Overall, case outcomes were categorized by clinicians as successful (54.3%), uncertain (23.9%) and unsuccessful (3.8%). CONCLUSIONS This web-based survey provides a valuable perspective on case selection, clinical protocols and perceived outcomes for REPs and supports the need for future higher level evidence studies.

Thakur V. Modified single-step apexification and strengthening of thin dentinal walls with Biodentine. JOURNAL OF CONSERVATIVE DENTISTRY AND ENDODONTICS 2024; 27:214-218. [PMID: 38463468 PMCID: PMC10923217 DOI: 10.4103/jcde.jcde_239_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 11/07/2023] [Accepted: 12/06/2023] [Indexed: 03/12/2024]
Abstract
Apexification is a technique used to create a mineralized barrier in a root having an open apex or to continue the apical growth of a root that is still not fully developed in teeth with necrotic pulps. Biodentine is a versatile material which can help in achieving apical closure as well as reinforcement of thin dentinal walls, thus improving the overall prognosis and preserving the natural dentition. In the present case, the radiographic evaluation showed thinner dentinal walls and an open apex with periapical radiolucency in relation to the upper right central incisor. The large open root apex and thin dentin walls of immature permanent teeth render them challenging to treat with root canal therapy. This case report describes a modified single-step apexification procedure and strengthening of the dentinal walls of the root canal using Biodentine.

Abstract
INTRODUCTION The aim of this study was to ascertain the current trends in regenerative endodontic procedures (REPs) among clinicians, including case selection criteria and clinical protocols. METHODS An online questionnaire consisting of provider demographics, case selection criteria for REPs, and clinical protocols was made available to members of the American Association of Endodontists and members of the Endolit website. Data were analyzed using the Fisher exact test. RESULTS Two hundred seventy-two responses were analyzed (64.6% were men and 34.7% were women). Of those, 44.5% of respondents practiced in the United States, and 55.5% practiced outside of the Unites States. Most respondents (85.4%) reported performing REPs in their practice, and 92.2% were using sodium hypochlorite as one of their disinfecting irrigants. Calcium hydroxide was the most commonly used intracanal medicament (68.4%), and the majority of respondents use a blood clot alone as the scaffold (73.5%). Most (93%) of the providers reported using a bioceramic material for coronal capping. Practitioners outside the United States were found to be more likely to use adjunctive irrigation activation (P = .003). Younger practitioners preferred REPs over apexification (P = .01). Practitioners outside the United States were more likely to perform an REP in 1 visit (P = .006). Men were found to be more likely to always instrument the canal walls (P = .031). Women were found to be more likely to use manual irrigant activation, whereas men were more likely to use sonic activation (P = .043). CONCLUSIONS There is significant heterogeneity within REPs regarding case selection and clinical protocol. Notable differences were observed from the reported findings of REPs from 5 years ago.

Abstract
Pulp involvement of immature permanent teeth with dentinogenesis imperfecta is challenging and could lead to extraction. A case of dentinogenesis imperfecta-induced periapical periodontitis of an immature permanent tooth was treated with regenerative endodontic treatment (RET), and root maturation was observed in 12-month follow-up. An 8-year-old girl presented acute pain and swelling in central mandibular region. Clinical and radiographic examination revealed "shell teeth" appearance of teeth 31, 41, and 42. Periapical lesion of tooth 31 was observed. Tooth 41 was previously treated with apexification. RET was planned and carried out for the necrotic tooth (tooth 31) with dentinogenesis imperfecta. The 1-, 3-, 7-, and 12-month postoperative recall revealed complete healing of periapical lesions. Root maturation characterized by elongation of root, thickening of dentinal walls, and closure of root apex was observed with radiographic examinations. We show that RET could be a desirable treatment for necrotic immature permanent teeth with dentinogenesis imperfecta and lead to resolution of endodontic lesions as well as maturation of dental root. The findings of this case suggest that RET should be considered by endodontist and pediatric dentist to treat teeth with similar dental anomalies and apical periodontitis.

Abstract
AIM To investigate current endodontic practices, adoption of technologies and continuing education attendance within specialist endodontic practice globally and to identify geographic trends. METHODOLOGY A web-based survey of endodontic association members in Australia, Britain, Canada, Italy, New Zealand and the USA on routine treatment preferences, armamentarium and education attendance was conducted. Chi-squared, independent sample t-tests, Cochran's Q test and McNemar's test were performed. RESULTS The survey was completed by 543 endodontists or endodontic post-graduate students. Almost all respondents used the dental operating microscope (DOM, 91.3%), engine-driven nickel-titanium instruments (NiTi, 97.6%), electronic apex locators (EAL, 93.0%), cone-beam computed tomography (CBCT, 91.2%) and calcium silicate-based materials (CSBMs, 93.7%). Dental dam was always used by 99.1%. Over half used irrigation adjuncts (81.8%), warm vertical compaction (74.6%) and heat-treated NiTi (60.2%). Geographic comparison between AP (Asia-Pacific, n = 78), AM (Americas, n = 402) and EM (Europe and Middle East, n = 63) was performed. AM and EM preferred single-visit treatment more (p < .001) and used higher sodium hypochlorite concentrations than AP. AM had more access to CBCT in the workplace (86.6%) than AP (65.4%, p < .001) and used CBCT for routine preoperative assessment (39.6%) more than EM (7.3%, p < .001). Almost all of EM used irrigation adjuncts (95.2%), more than AM (78.1%, p = .001). AP used steroid/antibiotic medicaments most (p < .001) and had the highest attendance at continuing education programmes. CONCLUSION Several endodontic-specific armamentaria have reached almost complete adoption within global specialist endodontic practice, whilst the continued uptake of newer technologies should be followed over time. Some practising philosophies varied significantly across different geographic regions.

Abstract
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.

Abstract
There are many inconsistencies in the protocols followed for Regenerative Endodontic Procedures (REP's).This study was formulated with an aim to conduct a survey among Pediatric Dentists, Endodontists and General Practioners treating Necrotic young permanent teeth to examine their awareness and Knowledge on Current Regenerative Endodontic Protocols and Scaffolds used in regenerative dentistry. Methods A Cross-Sectional Survey was carried out amongst 100 Pediatric dentists,100 Endodontists and 100 General Practioners. It was web-based survey and the questionnaire was formulated and all the items in the questionnaire were tested for reliability and validity before circulation of the questionnaire for the purpose of the study. Results The results of the study indicated that all the three groups were unaware that failure of cases should be reported to AEE (American Academy of Endodontics) REP Database and only 20.2, 20.1 and 0.3 % of Pediatric dentists,Endodontists and General Dentists preferred Regenerative Dentistry as a clinical protocol for REP. With respect to knowledge regarding irrigation and disinfection procedures all three groups were lacking in the knowledge regarding intracanal medicament for disinfection and the irrigation solutions. Conclusion There is a lack of homogeneity in protocols followed for REP among those practicing Regenerative Endodontics as a protocol. Since it's an evolving science there is a need to bring about a uniformity in practices to increase the evidences to support the causal effect relation of regenerative endodontics.

Abstract
Regenerative endodontic procedures have been rapidly evolving over the past two decades and are employed extensively in clinical endodontics. These procedures have been perceived as valuable adjuvants to conventional strategies in the treatment of necrotic immature permanent teeth that were deemed to have poor prognosis. As a component biological triad of tissue engineering (i.e., stem cells, growth factors and scaffolds), biomaterial scaffolds have demonstrated clinical potential as an armamentarium in regenerative endodontic procedures and achieved remarkable advancements. The aim of the present review is to provide a broad overview of biomaterials employed for scaffolding in regenerative endodontics. The favorable properties and limitations of biomaterials organized in naturally derived, host-derived and synthetic material categories were discussed. Preclinical and clinical studies published over the past five years on the performance of biomaterial scaffolds, as well as current challenges and future perspectives for the application of biomaterials for scaffolding and clinical evaluation of biomaterial scaffolds in regenerative endodontic procedures were addressed in depth. Overview of biomaterials for scaffolding in regenerative endodontics are presented. Findings of preclinical and clinical studies on the performance of biomaterial scaffolds are summarized. Challenges and future prospects in biomaterial scaffolds are discussed.

Abstract
Objectives Regenerative endodontic treatment is a clinical procedure aimed at biologically regenerating damaged root canal tissue of immature permanent teeth. This study aimed to report the outcomes of regenerative endodontic treatment performed by endodontic postgraduate students. Materials and Methods Clinical and radiographic data of 27 patients, aged 10–22 years, who underwent regenerative treatment of immature permanent teeth from 2015 to 2019 were followed up, wherein clinical and radiographic examinations were performed for each patient. Postoperative success rate and tooth survival were analyzed, and the postoperative radiographic root area changes were quantified. Results A total of 23 patients attended the dental appointments, showing that all teeth survived and were asymptomatic. Specifically, 7 periapical pathosis cases were completely healed, 12 were incompletely healed, and 4 cases failed. Moreover, significant differences were found between discolored and non-discolored teeth, and between the presence or absence of periapical radiolucency. Additionally, 3 anterior teeth showed complete closure of the apical foramen, while the apical foramen width was reduced in 17 teeth and failed in 3 teeth. Root length was also found to have been increased in 7 anterior and 4 posterior teeth, and the average length ranged from 4.00–0.63 mm in the anterior teeth, 2.85–1.48 mm of the mesial root, and 2.73–2.16 mm of the molar teeth distal root. Furthermore, calcified tissue deposition was observed in 7 teeth. Conclusions A favorable outcome of regenerative endodontic treatment of immature permanent teeth with necrotic pulp was achieved with a high survival rate.

Abstract
Regenerative endodontic procedure (REP) is a progressive treatment modality for immature permanent teeth with necrotic pulp. The ambiguousness about the predictability of REP outcome in relation to complete disinfection of the root canal system and the occurrence of discoloration still exists. The aim of this retrospective study was to analyze two treatment protocols on clinical success rate, radiographic root development and the occurrence of discoloration. Eighteen patients were treated by a single operator by either treatment protocol according to the American Association of Endodontists (AAEP, n = 9) or a modified protocol (MP, n = 9) with the use of 5% sodium hypochlorite and sandblasting. Patients were followed up after 3, 6, 9, 12, 18 and 24 months and clinical success, radiographic root development and the occurrence of discoloration were assessed. The clinical success of MP was significantly higher in two years follow-up (p = 0.015), but the change in radiographic root area was higher for AAEP (p = 0.017) and the occurrence of discoloration was higher in AAEP (p = 0.029). The use of 5% sodium hypochlorite for a longer period of time leads to a higher success rate. The sandblasting of the access cavity reduces the occurrence of discoloration.

[PMID: 35399766 PMCID: PMC8989169 DOI: 10.4103/jcd.jcd_428_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 10/14/2021] [Accepted: 10/19/2021] [Indexed: 12/02/2022] Open
Abstract
Aim: This study evaluated the effect of four intracanal medications commonly used in regenerative endodontic procedures on the bond strength of four calcium silicate-based materials, in which two are powder-to-liquid products (MTA and MTA-HP) and the other are ready-to-use materials (EndoSequence Root Repair Material Fast Set Putty [ERRM] and Bioceramic Repair [BIO-C Repair]). Methods: Ten bovine central incisors were selected and 4 slices (1.0 ± 0.1 mm) were prepared from each root. Next, four 0.8-mm wide holes were drilled in each slice and specimens were filled with one of the following intracanal medications: triple antibiotic paste, double antibiotic paste, calcium hydroxide with distilled water, and calcium hydroxide with 2% chlorhexidine gel. After 21 days, holes were filled with one of the materials: MTA, MTA-HP, ERRM, or BIO-C Repair. After storage, push-out test and failure analysis were performed. Data were submitted to analysis of variance in a 4 × 4 factorial scheme. Tukey's test was used for multiple comparisons. Results: The use of different interappointment dressings did not influence the results (P > 0.05). ERRM and BIO-C Repair presented significantly higher values than MTA and MTA-HP (P < 0.0001). Specimens showed a 100% occurrence of adhesive failures. Conclusion: The use of different intracanal medications presented similar impact on bond strength of calcium silicate-based materials. Ready-to-use ERRM and BIO-C Repair materials presented the best push-out values to dentine, whereas powder-to-liquid MTA and MTA-HP cements showed the lowest results.

The purpose of this study was to evaluate current trends in access cavity design and cleaning and shaping among endodontists. A survey was e-mailed to active members of the American Association of Endodontists. Data showed that most respondents used traditional (57%) or conservative (43%) access cavities; less than 1% reported using ultraconservative access cavities. A glide path was created by 93% of respondents; NaOCl was used as lubricant by 51% of respondents, while 28% used RC Prep, 9% used liquid EDTA, 7% used Glyde, and 2% did not use any lubricant. Most respondents used NaOCl at 5.25% or higher concentration. Smear layer was removed by 92% of endodontists. Apical gauging was mostly accomplished with hand files. Clinical preferences varied among surveyed endodontists and among different age groups. Currently, very few endodontists use ultraconservative access preparations. There was large variation among the respondents suggesting a possible need for quality guidelines.

Abstract
OBJECTIVE Pulp revascularization is an effective treatment for immature necrotic teeth. Calcium hydroxide has been used in pulp revascularization as an intracanal medication due to its antimicrobial action and the non-exhibition of crown discoloration and cytotoxicity for stem cells from the apical papilla. Our study aimed to investigate the clinical success and quantitative radiographic changes of root development in immature traumatized teeth using calcium hydroxide plus 2% chlorhexidine gel as intracanal medication. METHODOLOGY In this retrospective study, 16 patients were treated with a standardized pulp revascularization protocol. Calcium hydroxide and 2% chlorhexidine gel were manipulated in a 1:1 (v/v) ratio and inserted into root canals with Lentulo spirals (Dentsply Maillefer, Baillaigues, Switzerland). Patients were followed up for a period from 9 to 36 months for the evaluation of clinical and radiological data. Radiographic measurements of root length, root width, apical diameter, and MTA placement from the apex were quantified using software ImageJ. Wilcoxon test and t-test were used, according to nonparametric or parametric data, respectively, for changes over time in root length, root width, and apical diameter. RESULTS Fifteen teeth survived during the follow-up period (93.75%) and met the criteria for clinical success. Although the changes seem to be very small in many cases, significant increases in the average root length (14.28%, p<0.0001), root width (8.12%, p=0.0196), and decrease in apical diameter (48.37%, p=0.0007) were observed. MTA placement from the apex and age at the time of treatment was not significantly associated with the quantitative radiographic outcomes. CONCLUSIONS Pulp revascularization in traumatized immature teeth treated with calcium hydroxide plus 2% chlorhexidine gel as intracanal medication had high success and survival rates, showing periodontal healing and resolution of signs and symptoms. However, concerning the continued root development, the outcomes can still be considered unpredictable.

Abstract
AIM To present the application and the outcome of the regenerative endodontic therapy (RET) in a series of symptomatic immature mandibular molars with pulp necrosis and apical periodontitis and to review the relevant literature for the documentation of the procedure as a potential treatment option. METHODS Three young male patients were referred with pain in the left mandibular region resulting from pulp necrosis and apical periodontitis of the first permanent molar. Regenerative endodontic approach was performed for the complete resolution of the lesions and the thickening of the apical root canal walls. The databases of Medline, Pubmed and Google Scholar were also searched for articles in which a regenerative approach has been undertaken for the endodontic management of immature permanent molars with pulp necrosis and apical periodontitis. RESULTS Follow-up examinations showed that the teeth remained functional without any signs or symptoms. Final radiographic examination at 12, 18 and 36 months, respectively, revealed complete resolution of the lesions and complete apical closure in the two out of three cases. The search of the literature revealed the existence of only 25 clinical articles in which necrotic immature molars were treated by the regenerative approach. The total number of the treated teeth were 46. CONCLUSIONS Regenerative endodontic approach may be applied in posterior non-vital molar teeth with a possible favorable outcome. However, the literature support for the documentation of the procedure as a predictable and reproducible treatment option in posterior immature molar teeth is at present limited.

Abstract
Regenerative endodontics is a biologically based treatment designed for immature permanent teeth with necrotic pulp to replace dentin and root structures, as well as dental pulp cells. This procedure has become a part of novel modality in endodontics therapeutic manner, and it is considered as an alternative to apexification. In the last decade, numerous case reports, which describe this procedure, have been published. This therapeutic approach succeeded due to its lower financial cost and ease of performance. Although the clinical protocol of this procedure is not standardized and the effects of irrigants and medicaments on dental stem cells fate remain somewhat ambiguous, however when successful, it is an improvement of endodontics treatment protocols which leads to continued root development, increased dentinal wall thickness, and apical closure of immature teeth. To ensure a successful regenerative procedure, it is essential to investigate the appropriate disinfection protocols and the use of biocompatible molecules in order to control the release of growth factors and the differentiation of stem cells. This is the first review in the literature to summarize the present knowledge regarding the effect of intracanal irrigants and medicaments on the dental derived stem cells fate in regenerative endodontic procedures.

Abstract
BACKGROUND Knowledge, attitudes, and beliefs of the students are important for the Tissue Engineering in Endodontic practice. The opinion of these future dentists would ultimately will decide the endurance of REPs as routine procedures in endodontic practice. The aim of this study was to perform a survey to identify the knowledge, attitudes, and practices of undergraduate students about regenerative endodontic procedures (REPs). METHODS The questionnaire was obtained after cross-cultural adaptation of a questionnaire previously applied in USA and was applied to two hundred forty-eight undergraduates. Data were statistically analyzed. RESULTS Most of the students (82.9%) agreed that regenerative therapy should be incorporated to dentistry and 87.5% of them believed that stem cells banks would be useful for the tissue regeneration. Most participants (58.1%) would like to obtain an internship/tutoring that addresses REPs and 80.8% of participants think that the major obstacle to a patient accepting a REP was the expected high cost of the treatment. The freshmen students were more optimistic about offering stem cell treatments to their patients (P≤0.05). CONCLUSIONS The undergraduates were very optimistic about the future of REPs, stem cell banking, and tissue engineering. Although seniors demonstrated less enthusiasm towards REPs than the freshman, most students are willing to recommend these treatments to their patients.

Abstract
Continuing professional development (CPD) is needed in endodontics, and distance learning environments and courses may be preferable for CPD. Instructional designs (IDs) have been reported to strongly influence the educational effectiveness of these courses. Four Component Instructional Design (4C-ID) is an ID found to be effective for distance learning. The aim of this study was to evaluate the effectiveness of a distance learning CPD course on regenerative endodontic procedures (REPs) designed with a 4C-ID model. The study was conducted between April 2017 and March 2018 with volunteers from the 2015-16 graduates of Selçuk University's Faculty of Dentistry in Turkey. Pre- and posttests and skill assessment guide were used for assessment. To determine the participants' satisfaction levels, the Satisfaction Scale for e-Learning Process and an open-ended question were used. Of the 86 graduates invited to participate, 79.1% (n=68) responded they would; but the investigators limited the participants to 30, and the first 30 volunteers who had identified a need for REPs CPD were accepted to the course. Four (0.13%) had to drop out during the course, so data from the 26 who completed it were evaluated. The findings showed the difference between pre- and posttest results was significant (p<0.001). The mean score for psychomotor skills at the end of the course was 99.62±1.96 out of 100. On the satisfaction scale, the mean score for all participants was 138.5 on a scale from 29=lower satisfaction to 145=greater satisfaction with the e-learning process. At the end of the REPs course, the participants' knowledge levels had increased, and they were able to apply REP steps on a model. These results suggest the 4C-ID was effective in this distance education course in REPs.
