RESUMO Introdução: Protocolos de ensaios clínicos são documentos essenciais, que servem como base para o planejamento da pesquisa. As diretrizes do Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) objetivam aumentar a transparência e a integridade dos protocolos de ensaios clínicos. Objetivos: O presente trabalho descreve os principais aspectos do SPIRIT, destacando a importância do uso dessas diretrizes na Ortodontia. Resultados: O SPIRIT é composto por 33 itens e 1 diagrama, que foram aqui apresentados e explicados. Conclusão: O uso do checklist SPIRIT deve se tornar essencial, para aumentar a transparência e a integridade de ensaios clínicos na pesquisa ortodôntica, tornando-os mais confiáveis e menos tendenciosos, melhorando, dessa forma, a qualidade das futuras publicações nessa área.

ABSTRACT Introduction: Clinical trial protocols are essential documents that serve as a basis for research planning. The Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) statement aimed to increase the transparency and integrity of clinical trial protocols. Objectives: This paper described the main aspects of the SPIRIT, highlighting the importance of using this guideline in Orthodontics. Results: The SPIRIT is composed of 33 items and the diagram, which were presented and explained. Conclusion: The use of the SPIRIT checklist must become essential to increase the transparency and integrity of more reliable and less biased clinical trials in orthodontic research, improving the quality of future publications in this field.

Abstract This bibliometric study analyzed the 100 most-cited papers about the use of lasers and their modalities in dentistry. A search strategy was created using specific keywords related to the topic. A comprehensive search was then conducted in the Web of Science Core Collection (WoS-CC) database up to July 2021. Papers that addressed the application of any type of laser and its modalities in dentistry were included. Each paper was cross-matched with the number of citations on Scopus and Google Scholar. The following data were extracted from papers: title, number of citations, authorship, country, year of publication, journal, study design, subject, laser type, and oral health outcomes. The VOSviewer software was used to generate bibliometric networks. The total number of citations ranged from 120 to 4,124 and 23 papers received more than 200 citations. Papers were published from 1964 to 2015. Most papers were from Europe (42%) and Anglo-Saxon America (27%). The USA was the country with more top 100 papers (25%). Papers were published mainly in Lasers in Surgery and Medicine (15%) and Lasers in Medical Science (7%). VOSviewer maps demonstrated the existence of national and international research collaborations among institutions and authors. Most studies had a laboratory design (57%) and were about restorative dentistry (32%) and periodontics (21%). This bibliometric study of the top 100 most-cited papers on lasers in dentistry allowed a quantitative and qualitative analysis of this very promising research field, revealing a net of collaboration and the importance of this topic in dentistry.
