Nd:YAG laser therapy on postoperative pain, swelling, and trismus after mandibular third molar surgery: a randomized double-blinded clinical study
This study aims to evaluate the effect of Nd:YAG laser therapy (NdLT) on postoperative pain, swelling, and trismus after mandibular third molar (M3) surgery. Three hundred patients were randomly divided into the Nd group (n = 100), medication group (n = 100), and Nd+medication (Nd+m) group (n = 100). The WHARFE classification system was used to assess surgical difficulty. After surgery, the Nd group was irradiated by the Nd:YAG laser in very long-pulsed mode (VLP, pulse duration 1 ms, 20 Hz, 4 W, R21-C3) in 6 regions of the extraction socket with a total energy of 300 J. For the medication group, dexamethasone 0.75 mg and ...

The first meta-analysis research on the effects of endovenous laser ablation combined with sapheno-femoral junction high ligation of the great saphenous vein
AbstractEndovenous laser ablation (EVLA) is a common minimally invasive technique used to treat varicose veins. The most commonly used laser wavelengths for EVLA/EVLT of varicose veins are 810 nm and 1470 nm. The laser pulse frequency is typically set to continuous wave (CW) mode, with a pulse duration of a few milliseconds (ms) delivered in a radial mode. The energy delivered per pulse is typically set between 40 and 120 Joules, with a power setting of 10 to 30 watts and an intensity setting of 40 to 120 J/cm2. The controversy exists regarding the benefits of performing saphenofemoral junction (SFJ) ligation prior to EVLA...

Evaluation of photobiomodulation effect on cesarean-sectioned wound healing: a clinical study
This study reports a clinical examination of PBM under intervention group of 40 patients ranging 18 –40 years old with body mass index (BMI) of 29–36, during post-cesarean surgery to elucidate successful healing of the wounds and scars against conventional methods which considered as control group. Comparison of mean REEDA scores on the third day (p = 0.035), seventh day (p = 0.03), and tenth day (p = 0.02) after delivery exhibits that the two groups benefit a statistically significant difference with each other. For instance, the mean wound healing score in the intervention group was almost half of the me...

Comparative evaluation of fluoride-free remineralization agents with and without Er,Cr:YSGG laser on artificial enamel remineralization
This study aimed to evaluate the efficacy of fluoride-free remineralizing agents in initial enamel caries, with and without combined Er,Cr:YSGG laser application. The remineralization effect of various agents and their combinations on artificial initial caries was investigated using 10 experimental groups (n = 7): NC, negative control; PC, positive control; TM, calcium-phosphate compounds (CPP-ACP); TD, theobromine-containing toothpaste; RG, ROCS® remineralizing gel; L, Er,Cr:YSGG laser (2780 nm; 0.25 W; repetition rate, 20 Hz; pulse duration, 140 μs; tip diameter, 600 μm; without air/water cooling); L + f...

Dusting efficacy between the regular setting of holmium laser (Ho:YAG) versus Vapor Tunnel pulse modality for non-complex kidney stones
AbstractThe new pulse modality Vapor-Tunnel ™ (VT) consists of a very long pulse that uses the minimum peak power, causing the energy to pass through a previously created vapor channel or tunnel. The first part of the pulse creates a vapor channel, whereas the remaining energy is discharged immediately after, passing straight through the pr eviously created tunnel. The aim of this study is to compare the dusting efficacy between Ho:YAG laser with long pulse and Ho:YAG laser with VT for non-complex kidney stones. A retrospective comparative study of 236 patients who underwent retrograde intrarenal surgery using Ho:YAG las...

Comparative study of soft tissue surgery by visible and infrared laser radiation
AbstractTo compare the cutting properties of lasers with different wavelengths (445 nm, 532 nm and 808 nm) used in cutting blood-rich tissues. Porcine myocardial tissue was cut using 2.3–15 W laser radiation in contact and non-contact modes with an optical fiber or focusing handpiece. The cut depth and coagulation zone width were determined histologically. The 445-nm laser achieved the greatest cut depth for all cutting parameters (p < 0.01). The blue laser gave the smallest coagulation width to cut depth ratio. Results of the study are consistent with the assumption that a 445 nm blue laser may have bett...

High-intensity laser therapy in low back pain management: a systematic review with meta-analysis
AbstractLow back pain (LBP) is a widespread health issue affecting people globally and is the second leading cause of missed workdays. High-intensity laser therapy (HILT) promises to decrease pain intensity in LBP patients. The aim of this work was to evaluate the effect of HILT in adult LBP patients. We searched for randomized controlled studies (RCTs) published before January of 2023. Our primary outcome was pain intensity, while our secondary outcomes included disability and flexibility scores. We synthesized the evidence using RevMan v.5.4 and assessed methodological quality with the Oxford/Jadad scale and the Cochrane...

Monitoring of minerals level in dialysate during hemodialysis treatment of kidney patients using LIBS technique
AbstractChronic kidney patients may have difficulties in blood filtration to eliminate the waste from the blood and to maintain the level of the minerals in the blood. Hemodialysis (HD) is an artificial way to remove the waste from the blood of a kidney patient and to maintain the proper mineral level in the blood. Reverse osmosis (RO) water having less total dissolved solids (TDS)< 50 ppm is used to prepare dialysis fluid/dialysate in dialysis with two chemicals (electrolytes and salts such as sodium bicarbonate). To check the purity of RO water from various RO machines used to prepare dialysate, which is vital for t...

Er:YAG laser lithium disilicate crown removal: removal time and pulpal temperature change
AbstractSince the removal of resin-luted all-ceramic restorations is a challenge, the use of Er:YAG lasers has become popular. The aim of this study was to determine the removal time of monolithic lithium disilicate crowns in different thicknesses and heat transmission to pulp using Er:YAG laser. Forty-five full-coverage monolithic lithium disilicate crowns in 1 mm (n = 15), 1.5 mm (n = 15), and mixed thickness (n = 15) were resin luted on relevant extracted human maxillary first premolars and subjected to Er:YAG laser irradiation for crown removal after 24 h. Laser parameters for each thickness, respectively, were 5 W, ...

AbstractTo review the effects of photobiomodulation therapy (PBMT) on pain intensity and disability in people with plantar fasciitis (PF) when compared with control conditions, other interventions, and adjunct therapies. Systematic searches were conducted in five database randomized controlled trials (RCT). We only included randomized controlled trials (RCTs) in adults with PF that compared PBMT to placebo, as well as RCTs that compared PBMT to other interventions; and as an adjunct to other therapies. The methodological quality and certainty were assessed through PEDro Scale and GRADE approach, respectively. The data of c...

Influential Factors in the Efficacy of Hemoporfin-Mediated Photodynamic Therapy for Port-wine Stains
This study intends to observe the influential factors for the efficacy of HMME-PDT in the treatment of port-wine stains (PWS). A total of 551 patients with PWS of head and neck was enrolled in this retrospective study. Further screening the patients of facial PWS, 484 patients were chosen. Patients were treated with HMME-PDT. All patients received 1~3 sessions of treatment with 2~3-month intervals. We photographed the lesions before each session and 2~3 months after the last session. Ages, sessions, lesion subtypes, and previous treatment history were related to the response of HMME-PDT (P =0.032,P<0.001,P=0.012,P=0.003...
