A comparison of gingival depigmentation by Er:YAG laser and Kirkland knife: osmotic pressure and visual analog scale

Abstract

According to results of wound healing, OP and VAS, two depigmentation procedures can be used safely and effectively.

Most effective method for the management of physiologic gingival hyperpigmentation: A systematic review and meta-analysis

“…A total of 4989 studies with relevant titles were further scrutinized based on eligibility criteria. After removing studies on basis of irrelevant objective, protocols only, no abstract, no full text, in vitro studies, different study designs, only 25 studies[12131421222324252627282930313233343536373839404142] were finally selected to be included for data extraction. The PRISMA flow chart of the process is shown in Figure 1.…”

“…[23] Minimum follow-up was of 24 h, and the maximum follow-up was of 15 months. [3627] Out of 25 studies, 17 studies compared laser,[1214212223252628303132343637383941] 3 compared cryosurgery,[132442] 2 electrocautery,[2735] one radiosurgery[29] and 2 combination of laser and electrocautery, laser and graft. [3340] The control group in all the studies was surgical stripping.…”

“…[212225263032333536383940] Rest used Nd-YAG[23121428] and Er-YAG laser [Table 1]. [313437] The parameters assessed in the included studies along with the measurement scale are mentioned in Table 2.…”

“…[21222324273133354142] 16 out of 25 studies reported postoperative pain and discomfort. [12131421222324252728313436374142]…”

“…Majority of the studies reported pain both after 24 h and 1 week, few studies also reported pain after 3 and 6 months. Nine studies[122122232530363741] reported that laser is more comfortable and produces less postoperative pain, two studies were in favor of cryosurgery[1342] and remaining showed no difference [Table 3].
