“…The apparatus can allegedly penetrate 1-13 mm of non-pigmented tissue. [9][10][11] The readings on teeth 13, 23 before surgical treatment over the gum show very high values of Flux, CONC which may be attributed to either artifacts due to hand movement, patient movement, improper placement or too much pressure. These values are defined by calibration against a standard reference of polystyrene micro-spheres, as provided by the manufacturer.…”

“…13 Flux values may come from neighbouring areas as well, like lip -higher values due to muscle twitching after retraction or free and attached gingiva due to marginal periodontitis. 10,11 It has been proven that gingivitis increases blood flow due to blood stasis in tissues. 3 The surgical test measurement from inside the cystic cavity shows very low values of flux which may be due to the detrimental effect of the lesion over bone microcirculation or application of local anaesthesia with adrenaline.…”

Introduction: Laser doppler flowmetry is a non-invasive method of measuring microcirculatory blood flow in tissue. Using laser doppler flowmetry Moor VMS-LDF1-HP and CP1T-HP probe combined with Moor VMS-PC software to evaluate the state of the periapical lesion (cyst) before nonsurgical endodontic treatment with bioceramics (Well Root SP™) and compare it to a healthy vital tooth of the same type with no periapical lesions. Later the bony crypt of the cyst was evaluated with Moor VMSLDF1-HP and VP7BS-HP probe during periapical surgery after the cyst was ablated with Er: YAG laser Lite Touch™ (Sineron, Israel) and retrogradely obturated with TheraCal LC®. Then the cyst received a bioceramic bone graft. To our knowledge, this is the first time laser doppler has been used during periapical surgery to evaluate tissue perfusion. Lesion type was confirmed with a histological examination after surgery. Aim: Evaluate tissue perfusion of a periapical lesion before nonsurgical treatment and during surgical endodontic treatment with Er:YAG laser with the help of laser doppler flowmeter. Results: Laser doppler flowmetry shows that the cystic tooth has a decreased blood flow, decreased concentration, direct current, speed, and lower temperature compared to a healthy tooth of the same type. During periapical surgery, the direct laser blood flow evaluation of the surgical crypt shows different values of the flux, speed, direct current, concentration, and temperature, which could be attributed to the mechanical trauma, adrenaline in the local anaesthetic or laser irradiation of tissues. Conclusions: Laser doppler flowmetry is a valuable method to perform tissue evaluation before, during and after treatment. It allows us to follow up the healing and pathological dynamics of microcirculatory tissue changes as well as evaluate and compare different methods and materials for treatment of apical periodontitis.

“…This effect was also achieved by acting on the mitochondrial respiratory chain and/or on the membrane calcium channels. In vitro and in vivo studies have shown that LLLT and photoactivated disinfection (PAD) aided fibroblast and keratinocyte cell mobility, collagen synthesis, angiogenesis, and the release of growth factors [18][19][20][21][22][23][24][25][26][27][28][29][30][31]42,43]. Adjunctive antimicrobial photodynamic therapy displayed excellent results in terms of gingival health and periodontitis healing.…”

“…Photodynamic therapy with diode lasers amplifies the healing effect. Generally, light therapy by itself or as a complementary antibacterial treatment has a positive effect on the whole periodontal complex [18][19][20][21][22][23][24][25][26][27][28][29][30][31]42,43].…”

The current pilot study investigates the effects following removal of excessive gingival tissue, which is often necessary in fixed prosthodontic cases. The aim of the study is to assess gingival healing after diode laser gingivectomy prior to prosthetic procedures. Materials and methods: The healing process of the gingiva after the diode laser gingivectomy of 41 teeth was assessed. The following parameters were examined: recovery time of the gingiva, possibility to take the impression at the same visit, duration of the manipulation, bleeding during the procedure, tissue adherence to the instrument, postoperative hemorrhage on probing, postoperative pain, and wound healing in regard to tissue color, tissue contour, and appearance of the wound. Results: At the 24th hour, all gingival wounds were covered with fibrinous plaque and an erythematous halo. At the 72nd hour, in two cases (4.9%), this wound’s characteristic had already passed through to the next healing stage—granulated surface and normal pale pink color. A granulated surface in the 1st week was reported in 10 (24.4%) cases, and in all of the other 31 (75.6%) cases, complete healing was reported. In the second week, all wound surfaces had a normal pale pink color. Bleeding was self-limiting in most of the cases and negligible from a clinical point of view. The postoperative pain levels were low or nonexistent. There was lack of postoperative hemorrhage on probing after the first week in all examined cases. Tissue recovery in terms of tissue contour, color, and appearance of the wound was asymptomatic. Conclusion: within the limitations of this pilot study, the outcomes of the wound healing after laser gingivectomy aided the clinicians to perform the prosthetic procedures in the same visit.

“…The antimicrobial capacity of PAD and PBM is used for increasing the microbial reduction and pain levels in periodontal, restorative, endodontics, pediatric and implantology conventional therapy. [19][20][21][22][23][24] Viral inactivation and successful treatment of infections caused by the herpes simplex type I virus are proven. [25][26][27] A combination of an adequate light source and a photosensitized targeted to the specific pathogen -PAD, is essential for effective bacterial infection elimination.…”

Background: Clinical success and functional durability of indirect restorations depend on optimal dental health before the prosthetic treatment and the manipulation of the gingival tissues. The aim of the current article is to review the surgical and non-surgical laser methods that can be applied as periodontal preparation in fixed prosthodontics. Review results: Preprosthetic periodontal preparation includes conventional periodontal therapy (non-surgical) and periodontal resective (surgical) procedures - soft and hard tissue crown lengthening. The advantages of lasers in the latter are reduced bleeding, less postoperative discomfort and faster healing. Non-surgical preprosthetic preparation, on the other hand, aims at microorganisms’ level reduction. The variety of protocols, which reduce the microbial number significantly, show photoactivated disinfection as adjunctive therapy in infection treatment, especially in patients with resistant microorganisms and anatomical complications. Conclusion: Lasers can be applied as an alternative to the classic surgical and non-surgical means for periodontal procedures. Low-level laser therapy and photoactivated disinfection ensure faster bacteriolysis and affect the microorganisms locally, whereas systemic medicines influence the whole organism. Photodynamic therapy does not require maintaining high concentrations of the photosensitizer in the infected area, as it is when using antiseptics and antibiotics.
