{"title":"ENDOLIFT® and multi-wavelength laser photobiomodulation: a randomized controlled trial study on 96 subjects, treating skin laxity of the lower third of the face","authors":"L. Longo, R. Dell'avanzato, Diego Longo","doi":"10.4081/ltj.2022.298","DOIUrl":"https://doi.org/10.4081/ltj.2022.298","url":null,"abstract":"Background and aims: Many patients look for procedures that can achieve similar results to surgical lift avoiding the risks and possible complications of surgery. Endolift® and multi-wavelength (MW) Laser photobiomodulation (PBM) are considered two of the most effective procedures in the treatment of skin laxity and superficial wrinkles. We aimed to investigate the reduction of skin laxity of the lower third of the face treated with the Endolift® technique alone or in combination with MW Laser PBM. Materials and Methods: From June 2016 to June 2018, 96 subjects (18 M; 78 F) were included in this randomized controlled trial (RCT) conducted in two Italian institutions. The area treated was the lower third of the face. The subjects were classified using the Ptosis Scale (grade I-V) at T0, with a Pinch Test <1.9 mm. We selected only subjects’ grade 4, both males and females, 45-55-years old. Thirty-two subjects (6M; 26F) (group 1) were treated with the Endolift® procedure followed by a session of MW Laser PBM using a simultaneous nonsurgical laser therapy emission of three different wavelengths (532 nm, 808 nm, 1064 nm). The MW Laser PBM was repeated after 7, 14 and 21 days. Thirty-two subjects (6M; 26F) (group 2) underwent only the Endolift® session. 32 subjects (6M; 26F) (group 3) received only MW Laser PBM. Follow up visits were performed at days 60 (T60), 120 (T120) and 540 (T540) after the treatments. The study ended in December 2019 when all the subjects had been followed for 18 months. Results: The results of the three groups were evaluated using the Ptosis Scale at T0, T60, T120 and T540. The combination of the two treatments (group 1) achieved more rapid effects, while MW Laser PBM alone treatment (group 3) achieved the slowest effect. The median test for independent samples showed that all the differences between groups are statistically significant at each follow-up (p=0.000). Conclusions: The Endolift® laser in the last 15 years allows to achieve exceptional results in the treatment of skin laxity reaching the desired ‘soft’ rejuvenation model which is increasingly desired. MW Laser PBM, in combination with Endolift®, obtains better results. Although significant at T540, the effects of MW Laser PBM alone are slower to reach.","PeriodicalId":17981,"journal":{"name":"Laser therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46375645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cucinotta","doi":"10.4081/ltj.2022.294","DOIUrl":"https://doi.org/10.4081/ltj.2022.294","url":null,"abstract":"Background and aims: Dental caries are a widespread oral disease and a serious public health problem, starting by teeth demineralization, which is a loss of minerals such as calcium and phosphate. Modern caries treatment is aimed at preventing the disease progression by teeth remineralization which is a supply of minerals to the enamel. The most popular remineralization method is the treatment of teeth with fluoride. Er:YAG laser has also gained research attention as a method for improving the uptake of fluoride and phosphate by introducing chemical and morphological changes into the structure of enamel but, while some researchers described it as effective, others found no significant effect from its application. This work aimed to further study the effect of Er:YAG laser, alone or combined with fluoride, to dental enamel. Materials and Methods: Twenty upper central human incisors, extracted for periodontal reasons, were used in the study. Samples were demineralized by acetic acid and divided into four groups: a) control, b) fluoride + Er:YAG laser, c) Er:YAG laser alone and d) fluoride alone. The remineralization rate of teeth was estimated by Raman Spectroscopy. Results: In comparison with the control group, the phosphate peak’s intensity increased notably for the teeth treated by fluoride, but decreased slightly for the teeth treated with Er:YAG laser and with a combination of the laser and fluoride. Conclusions: With the limits of this study, due to the limited samples number, Er:YAG laser, alone and combined with fluoride, seems to be not effective, at the parameters used, for the enamel remineralization.","PeriodicalId":17981,"journal":{"name":"Laser therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42243717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bagni","doi":"10.4081/ltj.2022.299","DOIUrl":"https://doi.org/10.4081/ltj.2022.299","url":null,"abstract":"Background an Aims: For 2003 year until today we treated hundreds of patients with Central Nervous System Injuries (CNSI), using Non-Surgical Laser Therapy (NSLT) obtaining good results in terms of sensibility and movement. In order to increase muscle strength and to further explore new emerging synergies, we have also started using a physical therapy practice based on the most current knowledge about the motor control, called Grimaldi’s Muscle Shortening Maneuver (GMSM). Spasticity is often the most disabling symptom and the current therapies are still not able to heal it at all. The goal of our study is to suggest a new way of treatment of spasticity, supporting it with objective measurements of muscle thresholds. Materials and Methods: In 2016-2017, 36 patients with traumatic or degenerative CNSI were enrolled. Lasers used were 808 nm, 10600 nm, and 1064 nm, applied with a first cycle of 20 sessions, four a day. Patients were subjected to Grimaldi’s Muscle Shortening Maneuver (MSM) twice a day, ten sessions at all, working selectively on hypertonic muscles and their antagonists. Before treatment, tonic stretch reflex thresholds (TSRTs) in Gastrocnemius Lateralis (GL) were assessed through a surface electromyography (sEMG) device paired with an electrogoniometer. Antagonist muscle force (Tibialis Anterioris) was assessed by some electronic hand-held dynamometers. For the clinical measure, we used the Modified Ashworth Scale (MAS). All tests have been performed at the baseline (before starting treatments), after one week (at the end of the last treatment) and after a month. Results: Results were considered positive if the instrumental assessment procedure showed modifications in TSRT values and subjects improved their antagonist muscle strength. Results showed modifications in TSRT values at every follow up. The average comparison between the follow-ups was always statistically significant (p .000). The increase in Tibialis Anterioris muscle strength was statistically significant as well (p .000). MAS showed some differences between followups but not all of them are statistically significant (T0-T1 p .063, T1-T2 p .001, T0-T2 p .000). Encouraging results suggest a possible correlation between laser and MSM therapies and modifications of TSRT in spastic muscles. Conclusion: Associating laser treatment and Grimaldi’s Muscle Shortening Maneuver (MSM) seems to be effective on spasticity in patients affected by traumatic or degenerative CNSI. Obviously, this kind of study design showed a lot of limits however this clinical series could be an important hint for every researcher working in the complex field of spasticity, a symptom that is poorly defined and hardly treated.","PeriodicalId":17981,"journal":{"name":"Laser therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45036583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal effects of lasers on biological tissue have been elucidated using vibrational excitations approach of peptide groups (PGs). It was proposed a Hamiltonian which integrate excitations induced by laser pulses and it was shown that the system is governed by a nonlinear equation with strong nonlinearity. It was also exactly described what happens in polypeptide chain once the unwanted organ is irradiated by the Neodymium-doped yttrium aluminium garnet, chosen as incident laser. It was shown that, the advent of incident laser beams contributes to a sudden reinforcement of the vibrational excitations of PGs frequencies and amplitudes. It was also demonstrated that the heating process leads to transverse and longitudinal deformation of the polypeptide chain and these sudden changes lead to the denaturation and subsequently to the destruction of the bulky organ. The drawn curves make it possible to estimate the spatial expansion of the denaturation, in order to effectively control the spread of the heat. Laser irradiation leads to a drastic increase in the vibration amplitudes of the PGs and subsequently results in the destruction of the undesirable tissue. An appropriate choice of the laser can make it possible to circumscribe the destruction only in the defective zone and to protect healthy cells.","PeriodicalId":17981,"journal":{"name":"Laser therapy","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41577038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
