“…This corelates with the results of the other researchers investigating laser systems effects on the soft tissue in the oral cavity [8,9]. The advantage of the Er:YAG laser is a weeker penetration of the laser energy into the tissue (0.05 mm) and a presence of additional water cooling.…”

Background -In oral pathology, laser devices can provide important advantages, especially in the treatment of certain lesions. However, there is controversy about the use of some wavelengths in the analysis of suspected dysplastic or neoplastic lesions, raising doubt about the laser's suitability for use in biopsy procedures. The present pilot study evaluates the pathomorphological characteristics and suitability of Er:YAG and diode lasers for performing excisional biopsies in the oral mucosa with special emphasis on the extent of the thermal damage zone created. Material and Methods -10 patients were randomly assigned to one diode or one Er:YAG laser groups. The Er:YAG laser(2940nm) was used in a pulsed wave mode 200mJ/35Hz with a power of 7 W. Power settings for the diode laser(810 nm) were 3 W in a pulsed mode. The thermal damage zone of the two lasers and intraoperative and postoperative complications were assessed and compared.All biopsy specimens were evaluated by optical microscopy by threeblinded pathologists. After establishing the pathomorphological diagnosis of the lesion assessed, the pathologists measured the maximal width of the peripheral thermal damage zone in the specimen in μm and classified it using appropriate index. Results -The peripheral thermal damage zone on the borders of the excisional biopsies was significantly smaller with the Er:YAG laser compared to the diode laser regarding values in μm or pathomorphological index scores. No postoperative complications occurred in any of the two groups. Conclusions -The Er:YAG laser seems to be appropriate for excisional biopsies of benign oral mucosal lesions. The Er:YAG laser offers clear advantages in terms of smaller thermal damage zones over the diode laser. Although in some samples thermal damage was minimally visible, in all samples histological evaluation was clearly possible. The study demonstrated that the Er:YAG laser can be safely used in oral biopsy investigations while ensuring a successful histological evaluation, which is fundamental to correct clinical management.

Introduction: Recently, a wide variety of procedures have been done by laser application in orthodontics. Apart from the mentioned range of various treatments, laser has become a tool for many soft tissue surgeries as an alternative to conventional scalpel-based technique during orthodontic treatments in the management of soft tissue. Due to scarce information in the latter subject, this study was designed in order to include clinical trials that included soft tissue ablation by laser in orthodontics. Methods: Literature was searched based on PubMed and Google Scholar databases in 5 years (2010)(2011)(2012)(2013)(2014)(2015) with English language restriction and clinical trial design. Studies that performed soft tissue application of laser during orthodontic treatment were extracted by the authors. Results: Only eight studies met the inclusion criteria. No significant difference was found between laser ablation and conventional scalpel technique in the matter of treatment outcome. However, few issues remained to clarify the differences in the mentioned procedures. Conclusion: Laser performance can be recommended in case of preceding less bleeding and discomfort during surgical procedure. There are still quandaries among clinical application of scalpel-based surgery in aesthetic region with bracket-bonded teeth. Precaution and knowledge regarding the characteristics of laser beam such as wavelength, frequency, power and timing is extremely needed.

“…Laser assisted surgeries are easy to perform with less discomfort, minimal or no bleeding due to sealing of capillaries by protein denaturation and stimulation of clotting factor VII production, shorten healing time with reduced post operative bleeding and edema. 13 Histologically, laser wounds have been found to contain significantly lower number of myofibroblasts, thereby resulting in less wound contracture and scarring, and ultimately improved healing. Laser itself are antimicrobial and remove endotoxins from root surface.…”

Background: Ankyloglossia is another name for tongue tie which in mild form is characterized by mucous membrane bands to complete ankyloglossia whereby the tongue is tethered to the floor of the mouth. It can affect feeding, speech, and oral hygiene as well as have mechanical/social effects. Ankyloglossia can also prevent the tongue from contacting the anterior palate.Methods: The study aimed to find out best possible surgical modality of frenectomy by comparing scalpel, electro-cautery and CO2 laser in the treatment of tongue tie. This is a prospective randomized clinical trial conducted in the department of ENT, Dr. Shankarrao Chavan Government Medical College, Nanded, Maharashtra. All patients were categorized in to three groups randomly as group A, group B and group C. Each group contains 18 patients and among group A, B and C, frenectomy was done by conventional scalpel technique, by bipolar cautery and CO2 laser respectively. Then patients were assessed on post op day 1 for symptomatology and inflammatory signs, on post op day 7 for wound healing and any complications and also after 1 month post-op for scar and contracture of wound. Results: In our study, about 61% of population is of male child and female child were remaining 39% (ratio 1.6:1) which is matching with the previous studies. Amongst all patients most common age group is between 1-4 years of age group. Most of the patients were in Kotlow’s class III having severe ankyloglossia (3‑7 mm) followed by class I having Mild ankyloglossia (12‑16 mm).Conclusions: Laser and electro-cautery treatment used for frenectomy operations provides better patient perception in terms of postoperative pain and function than that obtained by the scalpel technique.
