SUMMARY:

“The interest in dental materials possessing satisfactory biological properties is directly linked to the therapeutic needs of dental structures, such as the dentin-pulpal and periradicular tissue interfaces, affected by defects of congenital origin or by trauma and diseases, such as caries. The search for the biocompatibility of dental materials was raised in Dentistry by favorable biological responses, observed by B. W. Hermann, in 1920, when he suggested the use of calcium hydroxide (CH) for the conservative treatment of dental pulp. Based on this evidence, several other dental materials have been suggested, such as calcium silicate-based cements, also known as "bioceramic cements", to which superior biological properties have been attributed. In this sense, the present study aimed to verify the performance of bioceramic cements in the periradicular repair process. For this, initially, celebrating the centenary of CH in Dentistry, a bibliometric review was developed with the objective of analyzing the 100 most cited articles on this dental biomaterial (manuscript 1). The bibliometric analysis was conducted in the Web of Science Core Collection (WoS-CC) database. Title, authorship information, study design, year, journal, number of citations, CH use, and fields of Dentistry were extracted. The number of citations in the WoS-CC, Scopus, and Google Scholar databases was cross-matched with the Spearman correlation. From the 1,596 papers identified, a list was compiled with the 100 most-cited papers. The number of citations in WoS-CC ranged from 78 to 384 (mean: 131.4). The main CH uses were: intracanal dressing (61%), and pulp protection (29%). The fields of Dentistry with most studies on CH were Endodontics (62%) and Operative Dentistry (30%). The most frequent study design was laboratory studies (44%). Three hundred and thirty-five authors from 29 countries were identified. The United States of America (USA) was the leading country with 23 articles. Dag Ørstavik was the author with the most papers and citations (9 papers; 1,118 citations). Most papers were published between 1991 and 2015 and in the Journal of Endodontics (38%). A very strong positive correlation was observed among the number of citations in the databases. The 100 most-cited papers were published mainly by European journals or from USA, with laboratory and multifaceted interventional designs. The present study celebrated the centenary of CH, highlighting the role and importance of this biomaterial in Dentistry. Finally, as a form of analyzing the existence of evidence that indicates a better performance of bioceramic cements in the periradicular repair process, in manuscript 2 a narrative review was presented with a systematic search. Following a manual search of 134 publications in the PubMed and Web of Science databases, a total of 72 publications from 2005 to August 2022 were reviewed (Supplementary file 1). Search terms were “calcium silicate cements” and “repair”. Included were English-language were publications that addressed biological properties of calcium silicate-based cements and provided sufficient details of methodology to be summarized in this narrative review. The descriptive data of the present review are presented mainly in terms of the ability to induce a positive cellular or tissue response to the periradicular tissue repair process. The data collected are intended to represent the status quo of the literature on favorable biological responses of calcium silicate-based cements in the periradicular repair process. Within the limitations of the available data in the literature regarding the biological properties and performance of the calcium silicate-based cements in the periradicular repair process, these biomaterials present themselves as promising alternatives; however, more research is needed to support this understanding.”
