“…Previous histological evaluations showed that 80% of PI grafts (24/30) (Harris, 2003) and 100% of DE grafts (5/5) presented epithelial remnants (Azar et al, 2019). Other forms of reducing epithelial remnants are high‐speed diamond burs (abrasion) (Marques de Mattos et al, 2020) or high‐level laser Er: YAG (Grzech‐Leśniak et al, 2018; Gursoy et al, 2019), Er, Cr: YSSG (Lin et al, 2018), Nd: YAG (Keskiner et al, 2016 aluminium, gallium and arsenide diode laser (Ozcelik, Seydaoglu, & Haytac, 2016). Thus, the amount of epithelial tissue remnant in grafts necessary to the development of cysts, epithelial inclusion and/or discharge release (Harris, 2003) remains unknown.…”
