“…Along with the advantages that the dental laser treatment can bring, a rare complication of subcutaneous emphysema has been reported [25][26][27]. It is known that subcutaneous emphysema may be caused by inappropriate use of the air projection system of dental lasers [27,28].…”

The prevalence of peri-implantitis and the absence of a standard approach for decontamination of the dental implant surface have led to searches for effective therapies. Since the source of diode lasers is portable, has reduced cost, and does not cause damage to the titanium surface of the implant, high-power diode lasers have been used for this purpose. The effect of laser irradiation on the implants is the elevation of the temperature surface. If this elevation exceeds 47 °C, the bone tissue is irreversibly damaged, so for a safety therapy, the laser parameters should be controlled. In this study, a diode laser of GaAsAl was used to irradiate titanium dental implants, for powers 1.32 to 2.64 W (real) or 2.00 to 4.00 W (nominal), in continuous/pulsed mode DC/AC, with exposure time of 5/10 s, with/without air flow for cooling. The elevation of the temperature was monitored in real time in two positions: cervical and apical. The best results for decontamination using a 968-nm diode laser were obtained for a power of 1.65 and 1.98 W (real) for 10 s, in DC or AC mode, with an air flow of 2.5 l/min. In our perspective in this article, we determine a suggested approach for decontamination of the dental implant surface using a 968-nm diode laser.

“…The literature review revealed five cases of emphysema following laser dental treatment in the English-language literature (including one of our cases) 1,[4][5][6][7] and seven cases in the Japanese-language literature (including one of our cases). [8][9][10][11][12][13][14] All 13 cases (one male, 12 females; mean age, 43.6 years; age range, 8-76 years) are summarized in Table 1 and all were reported from Japanese hospitals.…”

“…7 The Er:YAG laser manual suggests that air pressure towards the laser tip be lowered or turned off when irradiating a gingival sulcus 1 ; however, even if turned off, moderate air will continue to flow towards the tip for the purposes of cooling and protection. 1 Furthermore, when CO 2 or Nd:YAG lasers are used for soft tissue incision, a stream of cool air may well be needed to alleviate pain from the heat generated. In this review, nine cases had emphysema following laser irradiation for soft tissue incision, such as abscess incision and drainage, frenectomy, flap elevation, and gingivoplasty.…”

“…1 Heyman and Babayof 2 reviewed cases of emphysematous complications in dentistry reported between 1960 and 1993, and McKenzie and Rosenberg 3 later reviewed cases of iatrogenic subcutaneous emphysema caused by dental and surgical procedures reported between 1993 and 2008. Most cases were associated with the use of an air turbine or syringe during tooth extraction, restorative treatment, or endodontic treatment; only one case, reported in 2001 by Hata and Hosoda, 4 was associated with the use of a dental laser.…”

“…Since this time, the vast majority of cases arising in the dental setting have been associated with the use of air‐driven high‐speed handpieces and air syringes . High‐speed dental handpieces generating air have documented associations with SFE during the surgical removal of teeth and delivery of restorative treatment including direct restorations, crowns, and stainless steel crowns . Instances of SFE during endodontic treatment have been reported, an outcome typically linked to air from high‐speed handpieces and air syringes .…”
