Objectives The purpose of this research was to identify the top 10 most-cited articles on the management of fractured or broken instruments and to perform a bibliometric analysis thereof. Materials and Methods Published articles related to fractured instruments were screened from online databases, such as Web of Science, Scopus, PubMed, and ScienceDirect, and highly cited papers, with at least 50 citations since publication, were identified. The most-cited articles were selected and analysed with regard to publication title, authorship, the journal of publication, year, institution, country of origin, article type, and number of citations. Results The top 10 most-cited articles were from various journals. Most were published in the Journal of Endodontics , followed by the International Endodontic Journal , and Dental Traumatology . The leading countries were Australia, Israel, Switzerland, the USA, and Germany, and the leading institution was the University of Melbourne. The majority of articles among the top 10 articles were clinical research studies ( n = 8), followed by a basic research article and a non-systematic review article. Conclusions This bibliometric analysis revealed interesting information about scientific progress in endodontics regarding fractured instruments. Overall, clinical research studies and basic research articles published in high-impact endodontic journals had the highest citation rates.

Background Complete relief of pain due to irreversible pulpitis is challenging to obtain with analgesic medications. The high incidence of an inferior alveolar nerve block (IANB) failure makes it difficult for practitioners to perform endodontic treatment without implementing other anesthetic techniques, especially mandibular molars. The aim of this study was to compare efficacies of two different quantities of paraformaldehyde based pulpal medicaments to relieve the pain and control hyperemic pulp post-failure of IANB and supplementary technique in patients experiencing this symptomatic irreversible pulpitis in the permanent mandibular tooth. Method Eighty-two participants with severe pain pre-operatively (Heft Parker Visual Analogue Scale, VAS > 114 mm) were enrolled, and pain responses were recorded at different time intervals using the Heft Parker visual analogue scale. To the patients experiencing pain even after the administration of the standard IANB and supplemental intraligamentary injection, one of the two paraformaldehyde based pulpal medicaments was placed in the pulp chamber and sealed. Participants were recalled after 24–48 h (second visit) to assess pain and bleeding reduction. Results Results showed a significant decrease in pain severity and bleeding score post medicament placement (p < .05). Hence judicious use within a recommended period, pulpal medicaments can be considered safe. Conclusion Paraformaldehyde based pulpal medicament can be used as an alternative to manage pain in patients having severe irreversible pulpitis and hyperalgesia.

This study aimed to determine the prevalence and quality of endodontic treatment, by radiographically assessing the periapical periodontitis and endodontic treatment status in patients with cardiovascular disease (CVD) and cardiovascular risk (CVR) factors. Patients who visited the Out Patient Department of Institute of Dental Sciences and Department of Cardiology, Institute of Medical Sciences and SUM Hospital, Siksha ‘O’ Anusandhan University, Bhubaneswar, from August 2021 to February 2022, for a check-up or dental problem were considered as participants in this study. After obtaining informed consent, the participants were enrolled on the Oral Infections and Vascular Disease Epidemiology Study (INVEST) IDS, BHUBANESWAR. After testing negative for COVID-19, patients’ demographic details, such as age and gender were recorded, followed by a panoramic radiographic examination (OPG). A total sample of 408 patients were divided into three groups: Group 1/control (without any cardiovascular manifestation) consisting of 102 samples, group 2 of 222 CVR patients, and group 3 of 84 CVD cases. The CVR and CVD groups had a preponderance of elderly age groups between 60 to 70 years, with a significantly higher proportion of males. Co-morbidities such as diabetes mellitus, hypertension, and dyslipidemia were significantly associated with the CVR and CVD groups. From OPG interpretation, it was observed that the periapical radiolucency was greater in the CVR and CVD groups than in the control group (p = 0.009). The prevalence of endodontically treated teeth was higher in CVR and CVD than in the control group (p = 0.028). A high prevalence of dental caries, about 70%, was reported in all three groups (p = 0.356). The presence of dental restoration among all the groups was low (p = 0.079). The proportion of periodontal bone loss in the control group was significantly lower than CVR and CVD (p = 0.000). There was a strong association between periapical radiolucency, endodontically treated teeth, and periodontal bone loss in CVR and CVD patients. Notably, the associations reported herein do not reflect a cause-effect relationship; however, individuals with endodontic pathologies may accumulate additional risk factors predisposing them to hypertension or other CVDs. The results emphasize that eliminating local infections may decrease the systemic infection burden.

The objective of the present study was to evaluate the one-year clinical performance of lithium disilicate (LD) and zirconium dioxide (ZrO2) class II inlay restorations. Thirty healthy individuals who met the inclusion criteria were enrolled for the study. The patients were randomly divided into two study groups (n = 15): LD (IPS e.max press) and ZrO2 (Dentcare Zirconia). In the ZrO2 group, the internal surfaces of the inlays were sandblasted and silanized with Monobond N (Ivoclar, Leichsteistein, Germany). In the LD group, the internal surfaces of the inlays were etched with 5% hydrofluoric acid. The ceramic inlays were cemented with self-cure resin cement (Multilink N). Clinical examinations were performed using modified United State Public Health Codes and Criteria (USPHS) after 2 weeks, 4 weeks, 6 months and 1 year. The one-year survival rate was evaluated. In total, one failure was observed in the ZrO2 group. The survival probability after 1 year for the ZrO2 inlays was 93%, and for the LD inlays was 100%, which was statistically insignificant. The differences between both groups for most USPHS criteria (except for colour match) were statistically insignificant. Within the imitations of the present study, the lithium disilicate- and zirconia dioxide-based inlays exhibited comparable clinical performances. However, the colour and translucency match was superior for the lithium disilicate restorations.
