Item Lasers aplicados à frenectomia em pacientes pediátricos com anquiloglossia: uma revisão sistemática da literatura com metanálise(Universidade Brasil, 2020) Nunes, José Edson Pavini; Navarro, Ricardo ScarparoAnkyloglossia, or tongue stuck, is a condition in which the lingual frenulum is short, which can lead to problems with the nutritional suction of infants, inadequate breastfeeding, and which can cause fissures in the maternal nipples. Frenotomy or frenectomy can correct the restriction on the movement of the tongue and allow effective breastfeeding. Surgical intervention is performed with a scalpel, but in recent years the use of lasers in this procedure has increased. The aim of the study was to conduct a systematic review of high-powered lasers applied to frenectomy in pediatric patients diagnosed with ankyloglossia. In the methodology, a systematic literature review of randomized clinical studies with a score ≥ 6 on the PEDro scale (Physiotherapy Evidence Database) published in the PubMed, Cochrane and SciELO databases was performed. Studies were selected that evaluated the application of high-powered lasers in the surgical treatment of children with ankyloglossia, according to the PRISMA guidelines, using using descriptors: Ankyloglossia x Laser descriptors; Frenectomy x Laser; Phrenectomy x Ankyloglossia; Laser x Pediatric Dentistry; Ankyloglossia x treatment; Surgical Procedures x Ankyloglossia; Surgery x Lingual Frenulum; Surgery x Ankyloglossia, from clinical studies published from 2009 to 2019. The results showed that a total of 7 clinical studies were analyzed using high-power laser (diode or CO2) in frenectomy techniques. In 401 patients who underwent lingual frenectomy, superior benefits and results of the surgical technique with high-power laser compared to the conventional one with a scalpel were observed. It can be concluded that the lingual frenectomy surgery with high power lasers provides a more efficient and comfortable treatment for the infant patient compared to the conventional method, there is no consensus on the high power laser wavelength more suitable for the procedure and irradiation parameters.Item Inovação na epilação a laser: Triple wave de alta potência com resfriamento integrado(Universidade Brasil, 2024) Dorigatti, Jéssica Helena Franco; Tim, Carla Roberta; Garcia, Lívia AssisIntroduction: The search for methods of permanent hair removal has increased in recent decades, with the common use of high-power laser in clinical practice. Recent innovations have focused on the simultaneous emission of different wavelengths and application modes such as super hair removal (SHR) and hair removal (HR), with the possibility of cooling the tip for increased comfort and safety. Objective: This study aimed to compare the efficacy and safety of simultaneous application of three wavelengths in a combined protocol using SHR and HR methods for selective photothermolysis of hair follicles, compared to traditional SHR and HR methods. Methods: Forty-eight female patients aged 18 to 45 were included and divided into 3 groups: SHR Group: participants received triple wave laser application in a sweeping motion across the axillary area; HR Group: participants received 21 spot shots with triple wave laser distributed throughout the axillary region; SHR+HR Group: participants received SHR mode for the first 3 sessions and HR mode for the subsequent 3 sessions, following the procedures described in the previous groups. Interventions were performed bilaterally in the axillae with 30-day intervals, totaling 6 sessions with a 30-day follow-up after the last session. Evaluation methods included photographic assessment for hair count, skin temperature measurement, pain assessment using a visual analog scale, and patient satisfaction using the GAIS scale. Results: All three application methods resulted in a significant reduction in hair count, with no statistical difference between them. Patient satisfaction did not differ significantly between groups, as all groups reported satisfaction with the application methods. Pain perception differed across sessions, with SHR and SHR+HR methods showing lower pain levels throughout all sessions compared to the HR group. Adverse reactions evaluated included occurrences of edema and erythema, observed 30 minutes after each application, primarily in the HR and SHR+HR groups. Axillary temperature variations were less pronounced in the SHR group. Conclusion: The triple wave laser with cooled tip is effective and safe for hair reduction, regardless of the application mode.Item Avaliação dos efeitos fototérmico do laser de diodo λ1470 nm na pele em modelo experimental de ratos.(Universidade Brasil, 2024) Godoi, Silvana Aparecida Girão de; Assis, Lívia; Tim, Carla RobertaThe subdermal high-power diode laser is a therapy that has been frequently used as a treatment for skin aging. However, there is a need for studies to verify morphological and molecular changes in the skin triggered by this light technology. Thus, the objective of the present study was to evaluate the photothermal effects of diode laser wavelength (λ) 1470 nm on the skin of rats. 20 male Wistar rats were used, randomized into 2 groups: placebo laser (LP): treatment with subdermal laser turned off; active laser (LA): subdermal laser treatment was used. For therapy, high-power diode laser equipment was used (λ = 1470 nm; P = 2 W; beam area = 240 μm; beam divergence in rad: 0.227; continuous mode), applied in 5 subdermal vectors in the region of the animal's back in an area of 24 cm2 depositing an average of energy of 85 J/cm2, in a single session and the tissue was evaluated 15 days after the intervention. To evaluate the effects of the treatment, histological, morphometric analyzes and immunoexpression of transforming growth factor beta (TGF-β) and vascular endothelial growth factor (VEGF) were performed. The results demonstrated that active laser animals showed a better arrangement of collagen fiber bands and an increase in the thickness of the dermis and the number of vessels. Furthermore, animals treated with active laser showed an increased immunoexpression of TGF-β and VEGF compared to placebo. Thus, we can conclude that the subdermal high-power diode laser proves to be a promising option in aesthetic dermatology, as it was capable of increasing vascularization and the expression of factors that enhance skin rejuvenation.
