Clinical Study of Laser Biomodulation (650 λ) After Free Gingival Grafts
Vieira, Juliana P. P. G. / Lopes, Cibelle B. / DeMarco, Andrea Carvalho / De Melo Filho, Antonio Braulino / Jardini, Maria Aparecida Neves

Purpose: Free gingival grafts (FGGs) are used to increase keratinized tissue; however, this technique causes patients discomfort in the donor area. A biomodulation laser has been used in both in vivo and in vitro experiments to accelerate the healing process and modulate cellular metabolism. The purpose of this study was to investigate the intensity of pain as well as wound-healing chronology and quality in FGGs using laser radiation after surgery.
Materials and Methods: Ten patients with insufficient keratinized gingival tissue were randomly divided into two groups: control and laser (LED, 5 W, λ = 650 nm, and 8 J/cm2 at 0 h, 48 h and 72 h after surgery). The intensity of pain was evaluated using a numerical scale ranging from 0 to 10, where 0 is no pain and 10 is severe pain, on each of the 7 postoperative days. The wound healing of all patients was evaluated by visual inspection (7, 14 and 21 days after surgery).
Results: Statistically significant differences in pain level were found between the control and laser groups on days 1 and 2 after surgery (p < 0.05). The wound healing analysis showed that 80% of the irradiated patients and 40% of patients in the control group were healed 14 days after surgery.
Conclusion: The use of laser therapy improved the initial discomfort after FGG surgery. The results of this preliminary study have minor statistical significance because only a limited number of patients were included.

Advantages of Diode Laser (940 nm) over Surgical Blade in Management of Ankyloglossia: A Case Report
Doshi, Yogesh / Shah, Mona / Khandge, Nikhil / Sanghavi, Ankit

The lingual frenum has been a topic of controversy for a long time. Ankyloglossia causes problems in eating, dyspnoea, and speech disturbances. Hence, it is necessary to perform a lingual frenectomy in cases where ankyloglossia is very severe. Various methods such as surgery, diathermy, and lasers have long been used. The advantages of laser include a bloodless operating field, no postoperative infection or pain, and no suturing is needed. All these advantages are highlighted in this case report comparing the surgical technique with 940 nm diode laser for complete ankyloglossia.

Er,Cr:YSGG Laser-assisted Excision of Pregnancy Tumor
Yadav, Neha / Pahwa, Priyanka / Lamba, Arundeep Kaur / Faraz, Farrukh / Tandon, Shruti

Purpose: Periodontal health is compromised during pregnancy due to increased susceptibility to inflammation. Complications may arise in the form of gingivitis or tumor. The decision regarding treatment becomes a challenge to the clinician, as a minimally invasive and stressless procedure is a necessity. This case report describes the management of pregnancy tumor by excision with Er,Cr:YSGG laser in the 3rd trimester of pregnancy.
Materials and Methods: A 24-year-old pregnant patient at 36 weeks of gestation presented with a growth on the maxillary labial gingiva. The growth interfered with speech and mastication, causing discomfort to the patient. Er,Cr:YSGG laser at 1.50 W, 10% water, 11% air in continuous contact mode was used to excise the pregnancy tumor.
Results: Uneventful healing and preservation of the gingival architecture was achieved with the use of laser for excision.
Conclusion: The use of laser enabled a surgical procedure in the 9th month of pregnancy without infiltrative anesthesia, and it subjected the patient to minimal stress.

Therapeutic Laser in Surgical Procedures of Pediatric Dentistry: Case Reports
Machado, Maria Aparecida Andrade Moreira / Sakai, Vivien Thiemy / Silva, Thiago Cruvinel / Tessarolli, Vanessa / Carvalho, Flávia Patto / Moretti, Ana Beatriz Silveira / Santos, Carlos Ferreira / Oliveira, Thais Marchini

Pediatric dentists are always looking for new techniques, materials, and technologies which may help children to experience better and faster treatments. Low-level laser therapy (LLLT) has been increasingly used in medicine and dentistry over the last few years as a nonsurgical tool for pain control and wound healing improvement. LLLT can benefit the dental treatment and improve the relationship between the dentist, the children, and their parents. This paper describes the success of two cases in which LLLT was used after surgical procedures in pediatric dentistry. Neither patient reported painful symptoms or the use of any medicine during the postoperative period, suggesting a satisfactory and uneventful surgical recovery. In addition, the follow-up examinations revealed an ordinary wound healing of the surgical sites.

Treatment of Lower Lip Mucocele with Er,Cr:YSGG Laser - A Case Report
Chawla, Kirti / Lamba, Arundeep Kaur / Faraz, Farrukh / Tandon, Shruti / Arora, Shipra / Gupta, Manak

Mucoceles are benign, mucus-containing cystic lesions of the minor salivary glands. They are not true cysts since most of them lack an epithelial lining. These lesions occur most commonly in the lower lip. They are caused by trauma, orthodontic devices, or biting habits. This report presents a case of a 22-year-old male with a 3-mm mucocele on the lower lip. This lesion was removed using an Er,Cr:YSGG laser. The healing was uneventful and no suture or analgesic was required. The histopathological report confirmed the presurgical diagnosis. No relapse was observed up to one year after surgery.
