Scientometric evaluation of endodontic publications by Gulf Cooperation Council region in 21st century.

OBJECTIVES: The appraisal of research productivity is one of the key indicators to evaluate any area of knowledge. The current study aimed to analyze the Scopus-indexed publications on endodontics produced by Gulf Cooperation Council (GCC) region from 2000 to 2020. METHODOLOGY: The dataset was extracted in May 2021 from Elsevier's Scopus database. Two keywords ("endodontic" and "endodontics") were entered into the basic search with the Boolean operator of OR for a period of 20 years from 2000 to 2020. RESULTS: Overall, the GCC region contributed 2.82% of the global endodontic research. This share has shown a remarkable increase between 2001 and 2020 from 0.82% to 7.20%. About 60% of documents' volumes were produced during the 2016-2020 period. Around 80% of research was produced by Saudi Arabia, while research articles produced by Kuwait gained the highest citation impact. Out of the ten productive institutions, nine belonged to Saudi Arabia and one was from Kuwait. The majority of research collaboration was conducted with the United States, but research articles produced in collaboration with Japan yielded the highest citation impact. CONCLUSION: The study highlighted various scientometric attributes of endodontic publications produced by GCC affiliated researchers. The ongoing growth of endodontic literature by GCC countries along with the increasing international collaboration is considered aspiring.

Observance of proper mercury hygiene practices by Jordanian general dental practitioners.

OBJECTIVES: To assess the knowledge and observance of proper mercury hygiene and amalgam waste management (AWM) among Jordanian general dental practitioners (GDPs). SUBJECTS AND METHODS: Interviews were conducted with randomly selected 250 Jordanian GDPs, using a specially designed questionnaire. Out of the total of 250 GDPs, 228 (91.2%) agreed to participate. The questionnaire covered aspects related to professional information and total amalgam contact (TAC) of these practitioners. The second part focused on the degree of awareness of the protocols related to mercury hygiene and safe AWM. RESULTS: Mean TAC was 3.2+/-3.6 hours per week. Of the Jordanian practitioners, 22.6% reported no undergraduate training in amalgam safety measures. Almost a quarter of GDPs did not have proper ventilation in their clinics, around 20-25% did not use protective clothing or eye protection, 5.3% were mixing amalgam manually, and 13.9% used their bare fingers for inserting the freshly mixed amalgam. Most of unused amalgam ends up through the drain or in trash; there are no recycling facilities to be used. CONCLUSIONS: Most Jordanian GDPs do not strictly follow the mercury hygiene and AWM guidelines. Promoting the American Dental Association (ADA) guidelines through undergraduate and postgraduate training will help GDPs acquire proper attitude towards the proper hygiene practices described in these recommendations.
