Introduction: Intracanal medication with calcium hydroxide is an important adjunct to disinfection after the chemomechanical preparation. A dense and homogeneous filling up to the working length positively influences the outcome of endodontic treatment in infected cases. The optimum placement of intracanal medicament can many times become a challenging task, owing to the lack of usage of the appropriate instruments and techniques. Aim: The aim is to gather and assess available literature on the rationale of calcium hydroxide placement, instruments, and techniques for effective delivery. Materials and Methodology: An electronic search was conducted using the PubMed Database from 1970 to 2019 using the keywords “delivery of calcium hydroxide,” “placement of calcium hydroxide,” “density of calcium hydroxide.” The articles pertaining to the comparison between the placement techniques of calcium hydroxide dressing were analyzed. Results: The search identified 433 articles, from which 419 articles that did not fulfill the inclusion criteria were excluded from the study and eventually 13 research articles were analyzed for the review. Conclusion: The density of calcium hydroxide and the technique of placement may affect the healing outcome especially in cases of pulp necrosis with apical periodontitis. The use of lentulo spirals at lower speeds seems effective in intracanal delivery of calcium hydroxide.
