Referral to an oral surgeon for soft-tissue surgery before, during or after orthodontic treatment is not uncommon. This process may delay treatment and could potentially increase the risk of complications. In addition, seeing multiple specialties in different environments may demotivate paediatric or anxious patients from pursuing orthodontic treatment and could also adversely affect patient compliance and satisfaction. The development of laser technology provides a safe and effective alternative, allowing the orthodontic clinician to perform soft-tissue surgery. To date, there are no laser exposure protocols or UK guidelines regarding the use of laser surgery in orthodontics. This case series reports four clinical cases that demonstrate potential advantages of using a diode laser for the management of soft tissue in the field of orthodontics.

Introduction. Laser-induced thermal effects can preclude a safe histological evaluation of biopsy resection margins. The aim of this study was to evaluate the suitability of a 976 nm diode laser in oral soft tissue biopsies in an ex vivo study. Materials and Methods. A 976 nm diode laser (Solase®, Lazon Medical Laser, China) has been used in the contact mode, using a 400 μm fiber tip, at different parameters from 4 to 6 W in the continuous wave (CW), with a fluence between 3184 and 4777 J/cm2, and pulsed wave (PW) mode, with a fluence between 3184 and 4777 J/cm2, to obtain 30 samples from fresh pig cadaver tongues. All specimens were subdivided into 6 groups (from A to F), and each group consisted of 5 samples. Two sections were obtained from each sample. A histological analysis was performed using an optical microscope at magnifications of 5x and 10x. Statistical analysis was carried out using Kruskal–Wallis and Dunn’s tests. Results. The results showed that histological readability was optimal in all the samples. The thermal damage was negligible in all groups. The average thermal damage was 208.40 ± 133.81 μm in the epithelial tissue and 330.14 ± 147.45 μm in the connective tissue. The statistical analysis showed no differences between the groups ( p  > 0.05). Conclusion. A 976 nm diode laser demonstrated good surgical effectiveness that provoked little peripheral damage in the cut edges and allowed a safe histological diagnosis. Clinical Relevance. In oral pathology, many times, there is fear in using the laser to remove some lesions due to its thermal effect on the tissues close to the lesion. This effect is always present in the use of the laser, but the intent is to minimize this effect to have as little alteration as possible on the surrounding tissues.

Objectives: A sufficient histological evaluation is a key pillar in oncological treatment, especially in situations of cancer of unknown primary. CO2 laser technology is used in clinical routine of soft tissue surgery because of its cutting quality and availability. Diode pumped solid state Er(bium):YAG laser systems promise a higher cutting efficiency and minor thermal damages. The aim of this study was to compare both laser systems with respect to their suitability for cutting soft tissue.Methods: A setup was realized which enables comparable experiments with the clinical CO2 laser (AcuPulse 40ST DUO, Lumenis) and the Er:YAG laser system (DPM 40, Pantec Biosolutions AG). Fresh mucosal samples of porcine tongues were used to determine the influence of laser power and sample velocity on cutting depth and thermal damage width for both lasers. In addition, for the Er:YAG laser, the influence of the pulse repetition rate was examined additionally. For analysis, images of histological sections were taken.Results: In all experiments, the Er:YAG laser shows a significantly higher cutting depth (P < 0.0001) and less thermal damage width (P < 0.0001) than the CO2 laser. For example, at an average power of 7.7 W and a sample velocity of 5 mm/s the Er:YAG laser shows a mean cutting depth of 1.1 mm compared to the CO2 laser with 500 μm. While the Er:YAG laser shows a mean thermal damage width of 70 μm compared to 120 μm. Furthermore, the Er:YAG enables the adjustment of the cutting depth and thermal damage width by varying the irradiation parameters. A decrease of the repetition rate leads to a reduction of thermal damage. For example, a repetition rate of 100 Hz results in a thermal damage width of 46 μm compared to 87 μm at 800 Hz at an average power of 7.7 W and a cutting velocity = 5 mm/s while a homogenous cutting quality can be achieved.Conclusions: In conclusion, the results of these ex vivo experiments demonstrate significant advantages of the diode pumped Er:YAG laser system for soft tissue ablation compared to the CO2 laser, in particular regarding cutting efficiency and thermal damage width.

Now-a-days, almost every specialty area of dentistry is utilizing the powers of laser energy for therapeutic purposes. The diode laser is the most popular soft tissue laser and commonly used in dentistry. A diode laser with wavelengths ranging from 810 to 980 nm in a continuous or pulsed mode is used as a possible instrument for soft tissue surgery in the oral cavity. The 810 nm devices predominate in dentistry, whereas 810 nm is specific for hemoglobin absorption. Diode lasers have many advantages over traditional surgical and therapeutic techniques in addition to providing bloodless surgical and postsurgical course with minimal swelling, scarring, and others things noted are less pain, excellent hemostasis, rapid wound healing and bactericidal action with the minimally invasive procedure. In the present paper, we discuss various uses of the diode laser such as frenectomy, implant surgery, vestibular deepening, and gingival enlargement procedures in dentistry.
