Shaping Properties and Outcomes of Nickel-Titanium Reciprocation Systems in Primary Teeth: A Systematic Review and Meta-Analysis of In Vitro Studies

Abstract

The aim of this systematic review was to investigate the shaping properties and outcomes of reciprocating instruments in primary teeth. A search was conducted across various electronic databases such as PubMed, Scopus, EBSCO (dentistry and oral health sciences), LILACS, Cochrane, Google Scholar (first 100 hits), Open Grey, Ovid, and Shodhganga. Two authors independently performed data extraction and quality assessment of the selected articles using Rayyan software. A total of 12 studies were included. All 12 included studies qualified for qualitative analysis and five for meta-analysis. The meta-analysis revealed there was no statistical significance between rotary and reciprocating instruments concerning instrumentation time and canal transportation. The rotary and reciprocating instruments showed better shaping outcomes than hand instruments. Randomized controlled trials are required with adequate quality to perform a meta-analysis to provide better and more substantial evidence to use reciprocating instruments.

A instrumentação mecanizada no tratamento endodôntico de dentes decíduos: Uma revisão integrativa

“…Em seu estudo de metanalise Haridoss et al (2022) verificaram que em um intervalo de confiança de 95% houve diferença estatisticamente significativa entre os tempos de instrumentação das técnicas reciprocante e manual (razão de chance agrupada de 2,96;1,54; 4,37), todavia quando comparou-se os tempos de instrumentação entre as técnicas reciprocante e rotatória não foi verificada nenhuma diferença estatística (razão de chance agrupada de 0,63; -0,19; 1,45). O estudo ainda verificou que houve menos transporte no canal nas instrumentações mecanizadas que no manual, apesar de não haver diferença estatística entre as duas.…”
