The objective of this systematic review and meta-analysis was to compare the pain/anxiety levels associated with the anesthetic process by conventional and computer-controlled delivery systems (CCDS) in children. Four electronic databases (PubMed, EMBASE, Scopus, Google Scholar, and Dentistry & Oral Science Source/EBSCO) were comprehensively explored for eligible studies, in English or Spanish, published from January 1995 to December 2019. A systematic literature review and meta-analysis were conducted according to the PRISMA statement, including only randomized controlled clinical trials. An exhaustive search was performed in different electronic databases under a specific PICO-posed question. Relevant studies were selected based on titles and abstracts, and the full texts were retrieved. From these articles, important information was extracted. Wand demonstrated significantly lower pain than the conventional injection did. In the subgroup by pain scale analysis, the Facial Image Scale and Wong-Baker Faces Pain Scale showed a significant difference in favor of the CCDS. In general, the reviewed evidence shows that less perceived pain and anxiety occur when the local anesthetic technique is performed with a CCDS than with the traditional technique.
