ABSTRACT
Background: With rising trends in research and scientific writing, various ethical organizations have been vigilant over developing rigorous authorship criteria. There may be times, when authors tend to publish more due to their seniority or previously earned credit for former publications, proving the existence of Matthew effect in scientific research. It indicates that the majority of publications in a field are contributed by smaller number of authors. It was hypothesized that the Matthew effect may be still applicable for scientific work published by Indian pediatric dentists in the official Journal of Indian Society of Pedodontics and Preventive Dentistry (JISPPD) from 2015 to 2019. Methodology: To assess the number of times each author has published in the official Journal of Indian Society of Pedodontics and Preventive Dentistry, we downloaded all issues for the 5-year period from the journal website. Full names of all authors were entered year-wise in Microsoft Excel 2007 and descriptive statistics were used for finding out contribution percentages. Results: A total of 372 papers were published during the study period by 1148 authors. About 82% had at least one publication, followed by 12% publishing at least two papers; only 1% of the total authors had contributed to more than five publications. The result showed the absence of Matthew effect for publications in the JISPPD. Conclusion: The final results of the study did not show any presence of Matthew effect among authorship in the JISPPD.
ABSTRACT
Objective: The objective of this study was to determine the most suitable material for indirect pulp treatment (IPT) clinically and to determine the thickness (in mm) and type of tissue in terms of radiodensity (in Hounsfield units [HU]) formed after pulp capping using cone‑beam computed tomography (CBCT) scan. Materials and Methods: A longitudinal interventional single‑blind randomized clinical trial was conducted on 94 children (7–12 years) with a deep carious lesion in one or more primary second molar and permanent first molar without the history of spontaneous pain indicated for indirect pulp capping (IPC) procedure. About 109 teeth were treated using three materials, namely, calcium hydroxide (setting type), glass ionomer cement (Type VII), and mineral trioxide aggregate randomly. The teeth were followed up at an interval of 8 weeks, 6 months, and 1 year for success of IPT as per the American Academy of Pediatric Dentistry clinical criteria. For determining the thickness and type of dentin tissue formed, a CBCT scan was done immediately postoperative and another scan at an interval of 6 months. The scans were compared to evaluate the average thickness of the dentin bridge formed. Results and Conclusions: Success rate for IPC was 96.85%. A significant difference was obtained in the average thickness of reparative dentin at immediate postoperative and 6‑month postoperative values in all three groups suggesting distinct barrier formation. Similar significant findings were obtained in radiodensity of barrier formed (in HU). All three materials were found to be equally suitable as IPC agents suggesting mineral gain.
