Canine conundrum: Deciphering the factors at play - A systematic review.

The objectives of this systematic review are to identify the factors influencing the treatment duration to resolve impacted maxillary canines and to evaluate the time duration to resolve maxillary impacted canines considering these factors. A comprehensive electronic database search was conducted within a limited time period (from 01/01/2001 to 31/12/2023). The literature was sought and collected through PubMed, LILACS, Web of Science, Scopus, and EBSCO. The protocol was registered as CRD42024476064 in the PROSPERO database (http://www.crd.york.ac.uk/PROSPERO). The selection criteria were based on PI(E)COS. The searches retrieved 678 unique citations. Titles and abstracts identified 264 full articles, from which 19 remained after the inclusion criteria were applied. Factors such as the patient's age, the position and angulation of the impacted canine relative to the midline and lateral incisor, the side of the impaction, and the technique used to address the impaction have a statistically significant impact on the treatment duration for impacted canines. However, the influence of the patient's sex on treatment duration remains inconclusive.
