Comparison between contact diode laser with 980 nm and 1470 nm wavelengths for posterior laryngofissure in pigs. Sci Rep 2024; 14:11457. [PMID: 38769365 PMCID: PMC11106238 DOI: 10.1038/s41598-024-62333-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 05/15/2024] [Indexed: 05/22/2024] Open
Abstract
To compare two different wavelengths of the surgical contact diode laser (CDL) for producing a posterior laryngofissure in in-vivo pigs. Anesthetized pigs underwent a tracheostomy and an anterior laryngofissure through a cervicotomy. They were randomly selected for the CDL wavelength and Power, according to the peak of Power set at device (980nm wavelength: Ppeak power of 10 W, 15 W, and 20 W, or 1470 nm wavelength: Ppeak 3 W, 5 W, 7 W, 10 W). At the end of the experiment, the laryngotracheal specimen was extracted and sent for histology and morphometry measurements (incision size, depth, area, and lateral thermal damage). Hemodynamic data and arterial blood gases were recorded during the incisions. Statistical analysis of the comparisons between the parameters and groups had a level of significance of p < 0.05. Twenty-six pigs were divided into CDL 980 nm (n = 11) and 1470 nm (n = 15). There was a greater incision area at the thyroid level in the 980 nm CDL and a wider incision at the trachea level, with a larger distance between mucosa borders. There were no significant differences in the area of lateral thermal damage between the two groups and neither difference among the power levels tested. Both wavelengths tested showed similar results in the various combinations of power levels without significant differences in the lateral thermal damage. The posterior laryngofissure incision can be performed by either of the wavelengths at low and medium power levels without great difference on lateral thermal damage.

Photobiomodul Photomed Laser Surg 2024; 42:99-124. [PMID: 38294889 DOI: 10.1089/photob.2023.0109] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/02/2024] Open
Abstract
Objective: This study aimed to evaluate the impact of 10 adjunctive measures on non-surgical therapy outcomes for peri-implant disease. Methods: We formulated the study question and keywords following the Population, Intervention, Comparator, Outcome framework. Randomized controlled trials were identified through searches in PubMed, Embase, the Cochrane Library, and the Web of Science. Two researchers assessed the quality of included literature according to the Cochrane Risk of Bias Assessment Tool. Data analysis and ranking were performed using Stata 15.0 software. Results: This study, involving 51 pieces of literature and 2660 samples, conducted a network meta-analysis (NMA), which revealed that photodynamic therapy (PDT) significantly reduced probing pocket depth values in patients with peri-implant mucositis (SUCRA = 96.3%) and peri-implantitis (SUCRA = 96.7%). In addition, it showed an improvement in bleeding on probing (BOP) values for peri-implantitis (SUCRA = 91.6%). Furthermore, diode lasers improved BOP values for peri-implant mucositis (SUCRA = 76.5%). Conclusions: According to the NMA results and the surface under the cumulative ranking curve (SUCRA), PDT and diode laser outperform other adjuncts in peri-implant disease.

An In Vitro Study of the Effect of CO 2 Laser Power Output on Ablative Properties in Porcine Tongue. Life (Basel) 2023; 13:life13010162. [PMID: 36676111 PMCID: PMC9861084 DOI: 10.3390/life13010162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/27/2022] [Accepted: 12/31/2022] [Indexed: 01/09/2023] Open
Abstract
CO2 lasers have been generally used in oral soft-tissue surgery. Although an increase in power enhances the depth of ablation, the specific correlation between units of power and ablative depth has not been stated. This study aimed to explore ablative depth and width affected by a power unit of 10,600-nm CO2 laser continuous wave at 3 to 10 W in tissue blocks of the swine tongue. The 112 samples were randomly allocated into eight groups according to the power settings. The depth and width of the incision were measured by using the ImageJ program. The 3 W group showed the minimal depth of ablation [0.527 mm (0.474 and 0.817)] and width of ablation [0.147 mm (0.110 to 0.184)]. The maximal depth [3.750 mm (3.362 and 4.118)] and width [0.700 mm (0.541 to 0.860)] were in the 9 W group. The correlation between the ablative depth and power unit was 0.81 (p < 0.001). Based on the regression equation (p < 0.001), the ablative depth (mm) = (the power unit of laser in W × 0.491) − 0.731. In conclusion, the ablative depth of the CO2 laser on soft tissue was strongly correlated to power units enabling the prediction equation.

Comparison of Osseointegration of Dental Implants Placed in Rabbit Tibia Using Two Dental Laser and Implant Handpiece Systems. Bioengineering (Basel) 2022; 9:bioengineering9110681. [PMID: 36421082 PMCID: PMC9687135 DOI: 10.3390/bioengineering9110681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 11/08/2022] [Accepted: 11/10/2022] [Indexed: 11/16/2022] Open
Abstract
The present study aimed to confirm the usefulness of a multi-laser handpiece system currently under development. Implants were placed in the tibia of rabbits using a conventional separate laser-implant handpiece system (control group; SurgicPro+; NSK, Kanuma, Japan and Epic 10; Biolase, Irvine, CA, USA) and a multi-laser handpiece system (experimental group; BLP 10; Saeshin, Daegu, Korea). Implants were placed in left and right tibias of five rabbits using a conventional laser-implant handpiece system and a multi-laser handpiece system (N = 5 per group). Subsequently, micro-computed tomography (micro-CT; bone-to-implant contact evaluation), implant stability quotient (ISQ) measurement, and histological evaluations were performed to confirm the implant placement results. The independent t-test and the paired t-test were used to compare the ISQ values and the results of the two implant-laser handpiece groups (α = 0.05), respectively. No statistically significant difference in micro-CT, ISQ, and histological evaluations was observed between implant placement by the two systems (p > 0.05) except implant initial stability. The use of the multi-laser handpiece system is expected to produce the same results as a conventional separate laser-implant handpiece system with the higher implant initial stability. Additionally, it will potentially make the clinical environment more pleasant and will provide convenience for the clinicians.

Comparative Evaluation of Efficacy and Safety of the Diode Laser (980 nm) and Sclerotherapy for the Treatment of Oral Pyogenic Granuloma. Int J Dent 2022; 2022:8269221. [PMID: 36164597 PMCID: PMC9509284 DOI: 10.1155/2022/8269221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 08/30/2022] [Accepted: 09/05/2022] [Indexed: 11/23/2022] Open
Abstract
Background Pyogenic granuloma (PG) is a tumor-like, non-neoplastic lesion of the soft tissue that commonly appears in the oral cavity. Various treatment modalities have been discussed, including surgical excision, cryosurgery, curettage, electrodessication, corticosteroid injection, sclerotherapy, and lasers. This observational retrospective study compared effectiveness between diode lasers and sclerotherapy for PG treatment. Materials and Methods From July 2016 to January 2021, data of oral PG cases treated with sclerotherapy and diode lasers were gathered. Patients were evaluated and categorized according to their gender, sex, site of lesions, size of lesions, number of sessions, details of side effects, details of the VAS (Visual Analogue Scale) on third postoperative day, response of treatment to individual groups, time required for complete resolution, and details of recurrence. Inferential statistical analysis was performed. Results We included 73 patients, of whom 43 and 30 received laser and sclerotherapy treatment, respectively. Compared with the sclerotherapy group, the laser group had less side effects including pain, edema, ulceration, ecchymosis, infections, and scarring. The difference in postoperative pain (VAS scale) between the groups was statistically significant (p-value 0.004). Complete remission was seen in the laser group, while 3 cases of the sclerotherapy group had no response (p-value −0.034). The laser group experienced greater recurrence than did the sclerotherapy group. Conclusions Both sclerotherapy with laser and 3% sodium tetradecyl sulfate are effective for treating oral PG. Sclerotherapy is more effective in preventing recurrence. In terms of side effects, diode lasers are superior to sclerotherapy.

[PMID: 35931559 PMCID: PMC9676556 DOI: 10.1016/j.identj.2022.06.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 06/24/2022] [Accepted: 06/28/2022] [Indexed: 11/30/2022] Open
Abstract
The early detection and management of peri-implant mucositis may help in reducing inflammatory parameters and arrest disease progression to peri-implantitis. The potential therapeutic benefits of different adjunctive therapies, such as the diode laser, are still not completely understood. The objective of this systematic review and meta-analyses was to assess the outcomes of using diode laser on the management of peri-implant mucositis in terms of changes in periodontal parameters. Electronic databases were searched to identify randomised controlled trials (RCTs) that compared the combined use of mechanical debridement and diode laser with mechanical debridement alone. A specific risk-of-bias tool was used to assess the risk of bias. Data were analysed using a statistical software programme. In total, 149 studies were found. A meta-analysis of 3 RCTs showed no statistically significant differences in probing pocket depths (mean difference [MD], −0.36; 95% confidence interval [CI], −0.88 to 0.16; P = .18) or bleeding on probing (MD, −0.71; 95% CI, 1.58–0.16; P = .11) between the 2 groups at 3 months. In the management of peri-implant mucositis, the combined use of diode laser and mechanical debridement did not provide any additional clinical advantage over mechanical debridement alone. Long-term, well-designed RCTs are still needed.

Abstract
Introduction Leukoplakia is among the most common potentially malignant disorders encountered in clinical dental practice. The treatment of leukoplakia includes nonsurgical and surgical management. The surgical treatment includes excision, electrocauterisation, laser surgery or cryosurgery. This retrospective study aimed to analyse the efficacy of diode lasers in the management of leukoplakia. Methods The sample consists of 56 cases with 77 leukoplakia sites treated with diode laser between January 2018 and December 2020 with a minimum of six months follow-up. For each patient, personal data was collected along with site of lesions, leukoplakia phase, type of treatment performed (laser ablation or laser excision), side effects, recurrences and malignant transformation. Inferential statistical analysis was then conducted. Results After applying exclusion criteria, 56 cases with 77 leukoplakia sites were included in this study. Males aged >45 years were predominantly affected. Homogeneous leukoplakia (48.1%) was the most common phase. Recurrences were noted in 19.48% of the cases. Compared to laser excision, laser ablation had more recurrences. Gingival lesions showed a higher recurrence rate than other sites in the oral cavity. None of the cases showed malignant transformation. Discussion Laser offers many advantages over other conventional methods including lesser postoperative pain and swelling, bloodless dry operating field and increased patient comfort and requires minimal local anaesthesia. The study concluded that diode laser is an effective surgical treatment modality for treating leukoplakia. Furthermore, the laser excision technique was found to be superior to laser ablation due to lesser recurrence.

Thermal Effects of CO 2, KTP, and Blue Lasers with a Flexible Fiber Delivery System on Vocal Folds. J Voice 2022:S0892-1997(22)00074-1. [PMID: 35418349 DOI: 10.1016/j.jvoice.2022.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 03/06/2022] [Accepted: 03/08/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To determine the differences in thermal effects on vocal folds between four fiber-routed lasers. METHODS In this experimental laboratory study the thermal effects of an AcuPulse Duo CO2 (CO2 AP), UltraPulse Duo CO2 (CO2 UP), KTP, and Blue laser were analyzed using a Schlieren technique on a human tissue mimicking gel model. Power, laser duration, laser fiber distance to tissue and mode (continuous wave [CW] vs pulsed [P] modes) were evaluated in varying combinations in order to compare the effects of the tested lasers and to explore the individual effect on thermal expansion and incision depth of each setting. The model was validated by comparing the results from the Schlieren model with histology of ex vivo fresh human vocal folds after laser irradiation using a selection of the same laser settings, and calculating the intraclass correlation coefficient (ICC). RESULTS One thousand ninety-eight Schlieren experiments and 56 vocal cord experiments were conducted. In comparison with CW mode, less thermal expansion occurred in P mode in all lasers, while incisions were deeper in the CO2 and more superficial in the KTP and Blue lasers. The mean thermal expansion was found to be minimally smaller, whereas incision depth was pronouncedly smaller in the KTP and Blue compared to the CO2 lasers. Duration of laser irradiation was the most important factor of influence on thermal expansion and incision depth for all lasers in both CW and P modes. The ICC for consistency between the results of the Schlieren model and the vocal cord histology was classified from fair to excellent, except for the thermal expansion of the Blue laser, which was classified as poor. CONCLUSION This study demonstrates important differences in thermal effects between CO2, KTP, and Blue lasers which can be explained by the different physical characteristics of the P modes and divergence of the fiber delivery system. The Schlieren imaging model is a good predictor of the relative thermal effects in vocal fold tissue. Our results can be used as a guidance for ENT surgeons using fiber-routed lasers, in order to achieve effective treatment of vocal fold lesions and prevention of functional impairment of vocal folds.

A Novel Concept of Combined High-Level-Laser Treatment and Transcutaneous Photobiomodulation Therapy Utilisation in Orthodontic Periodontal Interface Management. SENSORS 2022; 22:s22062263. [PMID: 35336433 PMCID: PMC8951072 DOI: 10.3390/s22062263] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2022] [Revised: 02/23/2022] [Accepted: 03/14/2022] [Indexed: 02/04/2023]
Abstract
This case report is aimed to demonstrate the synergetic effects of λ940 nm laser photobiomodulation (PBM) therapy in augmenting the advantages of high-level-laser treatment (HLLT)-mediated reaction orthodontic periodontal interface management. Materials and Methods: A 32-year-old female who presented with a persistent gummy smile of upper incisors and low upper midline frenum attachment post-orthodontic treatment, was seeking a better smile appearance. She had a history of delayed wound healing without underlying medical conditions; otherwise, she was fit and healthy. She underwent laser ablation of the upper midline frenum and gingivoplasty of the upper incisors region with λ940 nm and λ2780, respectively, as well as transcutaneous PBM therapy (λ940 nm) to accelerate wound healing. The laser protocols were as follows: λ2780 nm: power output—2 W, pulse width—60 μs, free running pulse (FRP), spot area—0.0016 cm2, pulse repetition rate—25 pulses per second (s), 80 mJ/pulse, 90 s, λ940 nm: 1.2 W, continuous wave (CW) emission mode, 300 μm, 60 s; whereas the adjunctive λ940 nm induced-PBM parameters were as follows: power output—1.4 W, CW—120 s, single application, spot area—2.8 cm2. An acceleration of the wound healing was observed on the 4th day of treatment with no immediate or post-operative complications. The results showed no functional or aesthetic relapses at a long-term follow-up of 6 months. The authors concluded that λ940 nm laser-PBM can provide a synergetic effect to HLLT in accelerating wound healing and offering a precision smile with minimal to none post-operative complications. It is safe and justifiable to utilise dual therapy over the conventional methods, which serves our patients’ needs in our daily practice and in various clinical indications. The concept and laser protocols of this clinical case report can pave the roadmap for future extensive studies.

Abstract
Introduction: Genital condylomatosis is a highly contagious disease caused by the human papilloma virus (HPV). The aim of this prospective multicentre study was to evaluate the safety and efficacy of the Holmium:YAG (yttrium-aluminium-garnet) laser in the treatment of genital and intra-urethral warts; the secondary aim was to assess the patients' postoperative satisfaction and cosmetic results. Methods: From December 2016 to March 2019, patients with genital warts were prospectively enrolled in three hospitals. The inclusion criteria were male gender, age over 18 years-old and treatment-naïve. External and urethral genitalia warts were treated by the Holmium YAG laser. The follow-up analysis consisted of physical examination, flexible urethro-cystoscopy in case of meatal lesions, and administration of Dermatology Quality of Life Index (DLQI) and Patient Global Impression of Improvement (PGI-I) questionnaires at 1, 3, 6 and 12 months after surgery and subsequently yearly. Results: Sixty patients were enrolled. The single treatment was effective in 57/60 patients (95%). At a mean follow-up of 26 months, recurrences occurred in 8 patients (13.3%). No peri- or post-operative complication occurred. An improvement in pre-operative condition was highlighted with PGI-I and DLQI questionnaires. Conclusion: Our prospective multicentre study showed that holmium laser surgery seems to be a safe and effective treatment for external genital and urethral warts. Good dermatological outcomes aid to further improve patient satisfaction.

Abstract
Laser scalpels used in medical surgery concentrate light energy, heating the tissues. Recently, we reported thermoluminescence emission from laser-treated soft tissues. Here we investigated the thermo-optical effects caused by a laser operating at 808 nm on animal bones (beef ribs) through luminescence and fluorescence imaging, thermal imaging and scanning electron microscopy. Laser-induced artificial lesions emitted luminescence peaking around 650 nm, with a half-life of almost 1 hour. As concerns fluorescence, 24 hours after laser treatment we observed an increase of the emission and a shift from 500 (untreated) to 580 nm (treated). Recrystallization observed by SEM indicates that the temperature in the artificial lesions is over 600°C. We can conclude that laser treatment induces specific luminescent and fluorescent emissions due to heating of the bone and modification of its components. Monitoring these emissions could help prevent tissue overheating and its potential damages during laser-assisted medical procedures.

Hanke A, Fimmers R, Frentzen M, Meister J. Quantitative determination of cut efficiency during soft tissue surgery using diode lasers in the wavelength range between 400 and 1500 nm. Lasers Med Sci 2021; 36:1633-1647. [PMID: 33496905 PMCID: PMC8433103 DOI: 10.1007/s10103-020-03243-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 12/29/2020] [Indexed: 01/19/2023]
Abstract
Within the scope of this ex vivo study, the cut efficiency was investigated with eight diode laser wavelengths in the range from 400 to 1500 nm. Incisions on porcine gingiva samples were generated in CW-mode at a power range of 0.5–4 W using a bare fiber (∅ = 320 μm) in contact and non-contact mode at a cut speed of 2 mm/s. Cut depths, cut widths, and thermal damages were recorded based on histological sections and were evaluated via measurement masks. Moreover, with respect to the controllability of a therapeutic measure, an efficiency factor was defined. At powers above 2 W, for 445 nm, the maximum cut depth was 820 μm and 344 μm for 810 nm, respectively. At all wavelength and power ranges, the cut width averaged 125 μm. At minimum output power (0.5 W), the spatial expansion of the thermal damage in the tissue surface layer corresponds in the blue/green wavelength range from the very beginning of the laser impact to the fiber core diameter. It could be shown that increases in the diode laser power output do not correlate to the same extent with the incision depth nor with thermal damage to tissue.

Abstract
Objective: The aim of this study is to compare the conventional and diode laser techniques in terms of patient's perceptions, epithelization, reattachment, and periodontal clinical parameters in the treatment of abnormal papillary frenum. Materials and methods: Forty-eight patients with abnormal papillary frenum were enrolled in the study. Patients were randomly assigned into three groups; conventional frenectomy operation (C group), diode laser-assisted frenectomy (L group), and diode laser-assisted frenectomy with conventional horizontal incision on the periosteum (L + P group). Postoperative pain, discomfort in speaking, and chewing scores were assessed with visual analogue scale (VAS) at postoperative 3rd hour and on days 1, 7, 14, 21, and 45. Epithelialization process of the wound surface was evaluated by hydrogen peroxide solution applied to the wound on days 7, 14, 21, and 45 following operations. The distance between the frenum attachment point and mucogingival junction (FMGJ) was recorded at baseline, postoperative 45th day, and 6th month to assess the reattachment of the frenum. Plaque index, gingival index, bleeding on probing, and probing depth were recorded at baseline and postoperative 7th, 14th, 21st, and 45th days. Results: On the 1st and 7th day after operation, VAS pain score in the C group was significantly higher than in the L and L + P groups (p < 0.017). Difficulty in speaking and chewing scores were significantly lower in the L and L + P groups compared to the C group at postoperative 3rd hour and 7th day (p < 0.017). The FMGJ and epithelization period demonstrated no difference among the groups at any time point (p > 0.05). Conclusions: Our results suggest that diode laser provides better postoperative patient's perceptions than the conventional technique in frenectomy operation. In addition, both conventional and laser-assisted frenectomy surgeries prevent the frenum reattachment regardless of periosteal horizontal incision.

Abstract
OBJECTIVES To compare the efficacy and safety of diode laser and electrocautery techniques for inflammatory fibrous hyperplasia (IFH) removal. MATERIALS AND METHODS In this randomized double-blind clinical trial, 40 individuals were randomly allocated to two groups: group 1 (G1) consisted of 20 individuals assigned to treatment with diode laser and group 2 (G2) consisted of 20 individuals assigned to treatment with electrocautery. The following transoperative parameters were evaluated: bleeding, temperature, and surgical technique parameters (energy deposited on tissue, flow rate, and time of incision). The postoperative parameters evaluated were as follows: pain, functional alterations (chewing, speaking), analgesic medication intake, swelling, healing of the wound area, and patient satisfaction. RESULTS Among the 40 individuals included in the study, four (two in G1 and two in G2) did not complete the entire follow-up. Therefore, 36 individuals (18 in G1 and 18 in G2) participated. Participants in G1 and in G2 had similar demographic characteristics. No difference regarding the trans- or postoperative parameters evaluated was observed between G1 and G2 (p > 0.05). Also, no difference regarding the time for healing was observed between groups. CONCLUSIONS Diode laser seems to be as effective and safe as electrocautery when applied under similar conditions for IFH removal. CLINICAL RELEVANCE IFH corresponds to 65% of the lesions observed in denture wearers. This study shows that under similar conditions diode laser is as effective and safe as electrocautery for removal of IFH.

Abstract
<br/> Drug-influenced gingival enlargement (DIGE) is a reaction to specific medications, namely phenytoin, ciclosporin and calcium channel blockers. DIGE is encountered increasingly in clinical practice due to the widespread use of calcium channel blocker drugs particularly. Approaches to its management are discussed in this review.<br/> Methods: Narrative review of the literature and discussion of clinical implications.<br/> Findings: Management of DIGE involves nonsurgical treatment and may require surgical reduction of the overgrown gingival tissues. Management is complicated by the difficulties in achieving adequate plaque control, given the unfavourable contour of the enlarged gingival tissues, and the high frequency of recurrence of DIGE after surgical management. Replacing the drug involved can be very beneficial in selected cases, but the management of the underlying medical condition limits its application. The decision to replace a drug is not the responsibility of the dental practitioner, but the patient's physician may make it after consultation.<br/> Conclusions: Management of DIGE can be challenging and may require close co-operation between the dental practitioner and a hygienist, a periodontist and the patient's physician. Long term supportive maintenance programmes need to be in place for optimal outcomes.

Abstract
OBJECTIVE The aim of this study was to evaluate, ex vivo, the histological effects of 445-nm diode laser (Eltech K-Laser srl, Treviso, Italy), during an oral soft tissue biopsy. MATERIALS AND METHODS Thirty samples from pig cadaver tongues were obtained, through five laser settings, in continuous and pulsed wave (CW and PW). Samples were divided into six groups of five pieces each. A control specimen was taken by a scalpel. All samples were examined with an optical microscope by a blinded pathologist. Thermal effects on epithelium and connective tissues were measured with LAS 4.8 software. Finally, a statistical evaluation was made using GraphPadPrism 7.0 software. RESULTS All specimens, except one, showed a damage lower than 1 mm. Readability was always optimal; there was a different thermal effect between epithelial and connective tissue and in CW and PW samples, confirmed by statistical analysis too. CONCLUSIONS A 445-nm diode laser creates a minimum thermal effect, that has no implications in the histological evaluation of benign lesions. In suspicious lesions, a safety margin of 1 mm, compared with a scalpel, is preferable. CLINICAL RELEVANCE A 445-nm diode laser has excellent surgical properties and can manage many arduous clinical cases, such as vascularized lesions. In the excision of suspected lesions, it is necessary to compare, case by case, clinical advantages to possible histological implications.

Abstract
Objectives: The present observational study was conducted with an aim to evaluate the efficacy of diode laser in
management of homogenous oral leukoplakia (OL) and reticular oral lichen planus (OLP), so that these potentially
malignant disorders can be limited and further malignant transformation can be prevented. Further the assessment
of associated postoperative complications after laser therapy was also carried out. Study Design: Present study was
carried out using diode laser 810nm on 60 subjects, of whom 30 subjects were of homogenous OL and 30 subjects
were of reticular OLP aged between 20 – 60 years, the diagnosis of which was histopathologically confirmed. Results:
Of the 60 subjects none complained of pain during and immediately after surgery with no bleeding at any stage of the
procedure. By the end of 3rd day post operative most subjects reported no pain and swelling and very few subjects had
negligible pain and swelling when evaluated. On subsequent follow-up of 1,2 and 4 week(s) none of the subject reported
of pain, swelling or bleeding and it was noted that all the areas treated with laser had healed without scarring with no
signs of recurrence. Fibrosis was seen in two male patients and one female patient treated for OL and OLP respectively.
Conclusion: Patient compliance and contentment without any postoperative complications were observed to be of high
degree in the present study. Thus diode laser can be considered as a best alternative to conventional surgical treatment
modality in managing OL and OLP and preventing its further transformation.

Abstract
Background: Many challenges encounter the endodontist, especially when dealing with necrotic teeth with chronic periapical lesions. Postoperative pain may be induced following conventional endodontic therapy and total eradication of the bacteria is almost unachievable even with recently available techniques. In recent years, diode laser usage in the endodontic field has gained acceptance. Thus, this study aimed to investigate the ability of the diode laser (DL) to decrease postoperative pain and achieve root canal sterility. Methods: 56 patients with anterior teeth with chronic periapical lesions in upper anterior teeth were randomly divided into two groups (n = 28). All patients were treated with two visits of conventional root canal treatment with ProTaper Universal. The DL group: root canals were irradiated with 200 µm fiber optic at both visits; the control group (Endo): the DL fiber was placed in root canal with no activation. Bacterial samples were collected from all the cases at each step of the treatment. Pain levels were evaluated using a numerical rating scale preoperatively, and after 6, 12, 24, 48 hours and 7 days. Bacterial count was used to detect both aerobic and anaerobic bacterial load. Results: The qualitative pain scores revealed statistically significant lower pain levels in the DL group compared with the Endo group at all time intervals (P<0.001), except preoperatively where there was no significant difference. There was a statistically significant lower bacterial count for both aerobic and anaerobic bacteria in the DL group compared with the Endo group in both S3 samples (after laser application) and S4 samples (bacterial colonization) (P<0.001). Conclusion: The 980 nm diode laser may be a successful adjunct to conventional endodontic treatment of necrotic cases with chronic periapical lesions in terms of postoperative pain and root canal disinfection.

Abstract
OBJECTIVES The aim of this study is to evaluate secondary intention healing process and postoperative pain of oral soft tissues after laser surgery with the use of a compound containing chlorhexidine and sodium hyaluronate. MATERIALS AND METHODS This double-blind, randomized clinical study included 56 patients affected by benign oral lesions and subjected to excisional biopsy with diode laser and randomly divided into three groups. Study group (SG) received 0.2% chlorhexidine digluconate and 0.2% sodium hyaluronate treatment; control group (CG) received 0.2% chlorhexidine digluconate; and placebo group (PG) followed the same protocol, taking a neutral solution having the same organoleptic characteristics. Wound healing was evaluated using percentage healing index (PHI). Numeric rating scale (NRS) was used to evaluate postoperative pain. RESULTS PHI (T1 = 7 days) was 67.25% for SG, 58.67% for CG, and 54.55% for PG. PHI (T2 = 14 days) was 94.35% for SG, 77.79% for CG, and 78.98% for PG. A statistically significant difference was between the groups for PHI at T2 p = 0.001. No difference was detectable for pain index. CONCLUSIONS A solution containing sodium hyaluronate and chlorhexidine is a good support to increase wound healing by secondary intention after laser biopsy, but no differences were in postoperative perception of pain. CLINICAL RELEVANCE The use of the tested solution can be recommended after laser oral biopsies, to achieve a healing without suture. About the postoperative pain, the compound has not showed the same results and did not have measurable effects.

Abstract
The aim of the study was to evaluate the effect of diode laser as a phototherapy on surface treatment of fiber post and its bond strength to resin core build-up material. In this in-vitro study fifty fiber post of 1 mm tip-diameter and 20 mm length were used. The posts were mounted and randomly divided into 5 groups (n = 10) according to different surface treatment methods i.e. Group 1: Control, Group 2: Application of 37% Phosphoric Acid, Group 3: Treated with 40% H2O2, Group 4: Sandblasted with 50 μm aluminium oxide particles and Group 5: treated with diode laser. In all specimens including control, a cylinder of resin composite around the fiber post was made. All Specimens were mounted in a universal testing machine. Push-out test was performed and bond strengths were calculated. Using analysis of variance (ANOVA) and post hoc Tukey multiple comparisons test, means of push out bond strength were compared among the study groups. The highest bond strength was shown among Sandblasted [50 μm, Aluminium Oxide (Al2O3)] group [139.86] and the lowest push-out bond strength was observed in Control specimens [75.73]. The bond strength values of fiber post treated with Diode laser [100.81] and 40% H2O2 [105.64] were comparable.

Abstract
OBJECTIVE Diode lasers have multiple indications in everyday dental practice. They allow carrying out incisions, coagulation of soft tissue, and Low-Level Laser Therapy. The goal of this study is to compare histologically the tissue interaction zones and edges of an induced laser incision on rabbits' tongues with three different wavelengths of 810, 940, and 980 nm in continuous mode. METHODS Fourteen male rabbits were divided into six groups. Each animal underwent three incisions of 10 mm length on the right ventral face of the tongue, carried out in continuous mode with three diode lasers with different wavelengths of 810, 940, and 980 nm. Rabbits were sacrificed at 0, 1, 2, 6, and 15 hours and 14 days. Five rabbits were sacrificed at 0 hours and 2 hours and one rabbit was sacrificed at 1, 6, and 15 hours and at 14 days. The appearance of neutrophils marked the onset time of the inflammatory reaction. Histological study of the incisions was chosen to evaluate the edges and to measure the depth and width of carbonization and necrotic and inflammatory zones. Healing was evaluated at 14 days. Friedman test was used to assess statistical differences between groups. RESULTS In the experimental adopted conditions, the carbonization zone was marked by degradation of vacuoles and an elongation of nuclei and was observed on the edges of incisions. Carbonization and necrotic and inflammatory zones were measured for rabbits sacrificed at 0, 1, 2, 6, and 15 hours but the onset of inflammation zone marked by the infiltration of neutrophils did not appear before 6 hours. The neutrophils infiltration was higher at 15 hours than at 6 hours. Complete healing was shown at 14 days. According to the time for the regularity of the edges, the interpretation was qualitative without a statistical test. The statistical analysis of the three different diode lasers in this study showed nonsignificant difference between the different groups for the depth (p = 0.121) and width (p = 0.376) of the incisions, the carbonization zone (p = 0.692), and the necrotic zone (p = 0.223). For the inflammation zone at 6 and 15 hours, statistical analysis was not carried out; only one rabbit was enough to evaluate onset of neutrophils infiltration and to compare its density for 6 and 15 hours. CONCLUSION These results indicate that diode laser used in the continuous mode is predictable for induced incision. The use of three diode lasers with different wavelengths of 810, 940, and 980 nm did not reveal a significant statistical difference according to depth and width of the incision and for carbonization and necrotic zone. The appearance of neutrophils was marked between 4 and 6 hours and was higher at 15 hours.

Abstract
Background The aim of this study is to evaluate the resection of hyperplastic lesions on the buccal mucosa comparing the 532nm laser (KTP), versus diode 980nm laser, considering pain, scarring, inflammation and drug consumption that occurred postoperatively with each lasers. Material and Methods A prospective study of consecutive series of 20 patients in two groups that presents hyperplastic lesions on the buccal mucosa. The choice of the KTP laser or diode 980nm laser for the surgery was made randomly. The power used was 1.5W in both groups in a continuous wave mode with a 320 μm optical fiber. Parameters of pain, scarring, inflammation and consumption of drugs were recorded by a Numerical Rating Scale and evaluated postoperatively. These recordings were made the day of the surgery, 24 hours after, 14 and 28 days after. Results Pain and inflammation was light - moderate. The consumption of paracetamol was somewhat higher in the diode 980nm laser versus the KTP laser after 24 hours, although data was not statistically significant; significant differences were found after 28 days in regards to pain (p = 0.023) and inflammation (p = 0.023), but always in the absence parameter so we find no pain in both lasers. Scarring in the two types of laser showed no differences along the visits, with not detected scar retractable. Conclusions Although there is a slight histological difference regarding the KTP laser in the oral soft tissues for clinical use, both wavelengths are very suitable for excision of oral fibroma. Key words:Laser surgery, Laser therapy, oral surgery, soft tissue, 980 nm diode laser, 532 nm KTP laser.

Abstract
PURPOSE To report the outcomes of transcanalicular diode laser-assisted revision surgery for failed dacryocystorhinostomy with/without distal or common canalicular obstruction. METHODS The medical records and recorded videos of consecutive transcanalicular diode laser-assisted revision surgeries performed for failed dacryocystorhinostomy between May 2011 and May 2015 were reviewed. Cases of unavailability of video and cases lost to follow up after surgery were excluded from the study. With respect to the level of obstruction, lacrimal drainage systems were divided into Group 1 (obstruction at the level of the ostium) and Group 2 (obstruction at the level of the distal or common canaliculus). Data associated with anatomical and functional success were analyzed. RESULTS Revision dacryocystorhinostomy surgeries were performed on 68 patients during the study period. Transcanalicular diode laser-assisted revision surgeries were performed on 48 eyes of 39 patients. Mean follow-up period after revision surgery was 13.3 ± 12.6 months. Overall, anatomical success rate was 83.3% (40/48) and functional success rate was 68.8% (33/48). Anatomical success rates and functional success rates in the 2 groups showed no significant difference (80.0% [24/30] vs. 86.7% [13/15], p = 0.699; 70.0% [21/30] vs. 66.7% [10/15], p = 1.000, respectively). CONCLUSIONS Transcanalicular diode laser-assisted revision surgery may be an alternative technique for failed dacryocystorhinostomy. Distal or common canalicular obstruction did not affect the outcomes of revision surgeries.

Abstract
Introduction: Mucus extravasation cyst is a commonly occurring lesion in oral cavity that may result from traumatic severance of a salivary gland duct with subsequent extravasation of mucus into fibrous connective tissue. After a conventional excision or marsupialization, recurrence is not uncommon. Diode laser offers an effective modality for management of such lesions. Case Reports: Four patients were referred with painless fluctuant swellings on labial and buccal mucosa. After recording history and clinical examination, provisional diagnosis of mucocele was made. All the lesions were excised with a diode laser and biopsy was performed. Surgical wounds were treated with low-level laser therapy (LLLT). Results: Uneventful healing was observed in all 4 cases. Significant reduction in postoperative discomfort was recorded after application of LLLT. Histopathological findings were suggestive of mucus extravasation cysts. Conclusion: Diode laser appears to be a good alternative to conventional modalities for the management of mucus extravasation cysts.

Abstract
Introduction: Oral lichen planus (OLP) is a mucocutaneous disease with uncertain etiology. As the etiology is unknown standard treatment modalities are not available. The traditional and common treatment relies on corticosteroids whether topical or systemic. In recent years, development of lasers made a proper path to use this instrument for treatment of the diseases which are refractory to conventional treatments. Previous studies in this field used CO2, ND:YAG, Excimer and some wavelength of diode lasers for the treatment of different types of lichen planus. Case Report: In this study, we present an OLP case which is treated using 980 nm diode laser. The result was measured by visual analogue scale (VAS) and clinical assessment; as a result, symptoms including pain and soreness started to decrease within a week, and by the end of a month completely subsided; the lesion disappeared totally as well. No recurrence was observed after a month and no side-effect was reported. Conclusion: 980 nm diode laser can be successfully used for treatment of patients with OLP.

Abstract
Laser irradiation has numerous favorable characteristics, such as ablation or vaporization, hemostasis, biostimulation (photobiomodulation) and microbial inhibition and destruction, which induce various beneficial therapeutic effects and biological responses. Therefore, the use of lasers is considered effective and suitable for treating a variety of inflammatory and infectious oral conditions. The CO2 , neodymium-doped yttrium-aluminium-garnet (Nd:YAG) and diode lasers have mainly been used for periodontal soft-tissue management. With development of the erbium-doped yttrium-aluminium-garnet (Er:YAG) and erbium, chromium-doped yttrium-scandium-gallium-garnet (Er,Cr:YSGG) lasers, which can be applied not only on soft tissues but also on dental hard tissues, the application of lasers dramatically expanded from periodontal soft-tissue management to hard-tissue treatment. Currently, various periodontal tissues (such as gingiva, tooth roots and bone tissue), as well as titanium implant surfaces, can be treated with lasers, and a variety of dental laser systems are being employed for the management of periodontal and peri-implant diseases. In periodontics, mechanical therapy has conventionally been the mainstream of treatment; however, complete bacterial eradication and/or optimal wound healing may not be necessarily achieved with conventional mechanical therapy alone. Consequently, in addition to chemotherapy consisting of antibiotics and anti-inflammatory agents, phototherapy using lasers and light-emitting diodes has been gradually integrated with mechanical therapy to enhance subsequent wound healing by achieving thorough debridement, decontamination and tissue stimulation. With increasing evidence of benefits, therapies with low- and high-level lasers play an important role in wound healing/tissue regeneration in the treatment of periodontal and peri-implant diseases. This article discusses the outcomes of laser therapy in soft-tissue management, periodontal nonsurgical and surgical treatment, osseous surgery and peri-implant treatment, focusing on postoperative wound healing of periodontal and peri-implant tissues, based on scientific evidence from currently available basic and clinical studies, as well as on case reports.

Abstract
Ankyloglossia entails short lingual frenum, impairing satisfactory tongue movement and leading to problems related to deglutition, feeding and diction. This clinical report uses laser technology, rather than traditional surgical procedure with scalpel, to perform a lingual frenulotomy on a 9-year old child diagnosed with ankyloglossia, aiming to investigate more conservative and less traumatic dental procedures. Due to the many advantages of the laser device, such as bloodless surgical field, absence of sutures, minimal swelling and post-surgical pain, the high intensity diode laser is a viable alternative technique in soft tissue surgeries.

Abstract
BACKGROUND To evaluate the safety, convenience and effectiveness of 940nm diode laser for treatment of homogenous leukoplakia. MATERIALS AND METHODS Ten patients having homogenous leukoplakia which were diagnosed clinically were selected from an Indian dental educational institution for the study. Toludine blue staining was applied locally over the lesion. The area where there was increased uptake of stain was excised using a 940 nm EZLASE TM diode laser (BIOLASE-USA). RESULTS Although various treatment modalities have been tried and the search continues for novel treatment modalities for complete removal of homogenous leukoplakia, from results of our preliminary pilot study it is clear that the use of 940 nm diode laser as a treatment modality for homogenous leukoplakia is a good substitute. Healing was perfect without any complication within a duration of 1 month. Pain intensity was also mild and absolutely zero on the VAS scale after 1 month follow up. CONCLUSIONS 940 nm diode lasers are safe and can be effectively used as a treatment modality of homogenous leukoplakia, without any complication and without compromising health and oral function of patients. Considering recurrence factor, long term follow up for patients is a must.

Abstract
BACKGROUND Lasers have become standard tools for the surgical treatment of oral lesions. The purpose of this study is to determine the surgical margins and histologically evaluate the tissue thermal effects induced by different types of surgical instruments. MATERIAL AND METHODS Cuts were made in pork tongues' mucosa with different lasers (Er:YAG at 2W with and without air / water spray and at 4W with and without air / water spray; CO2 at 3.5W and 7W in pulsed mode and at 7W in continuous mode; the diode laser at 3.5W and boost 3.5W in pulsed mode; Nd:YAG at 6W, 40Hz and electroscalpel at 5W and conventional scalpel as control. Macroscopic and microscopic morphological changes were evaluated. RESULTS The results of this study showed that the surgical instruments that caused greater tissue damage extension were: the Nd:YAG laser (670.68μm), the diode 3.5W and boost PW (626.82μm), the CO2 7W CW (571.18μm), the CO2 at 7W PW (485.45μm), the diode 3.5W PW (456.15μm), the electroscalpel (409.57μm) and lastly the CO2 laser 3.5W PW (306.19μm) and Er:YAG (74.66μm) laser, regardless of power, mode or air / water spray used. An association between the Tissue Damage Extension and the Degree of Carbonization (r = 0.789; P = 0.01), and an association between the Tissue Damage Extension and Regularity of the Incision were found (r = -, 299; P = 0.01). CONCLUSIONS The results of this study suggest that lasers can be used in soft tissues biopsies of the oral cavity, enabling a correct histopathological analysis, as long as the biological effects of each laser type are considered. The Er:YAG laser revealed its potential for biopsies of the oral mucosa ensuring a successful histological evaluation and the CO2 laser at 3,5W in pulsed mode presented itself as the best choice for surgeries with hemostasis. Key words:CO2 laser, diode laser, Er:YAG laser, laser surgery, Nd:YAG laser, oral mucosa, thermal effect.

Abstract
Introduction: Laser surgery has been considered a popular alternative over conventional modalities in dentistry during the last few years. Among different types of lasers, diode lasers have gained special attention in oral soft tissue surgery. Case Reports: Five patients were referred to a private office. After careful evaluation of medical history and oral examination, oral diagnosis and treatment plan of each patient was established as follows: (1) A 21-year-old female with ankyloglossia (tongue-tie); (2) A 65-year-old female with a poor denture fit needing vestibuloplasty and frenectomy; (3) A 10-year-old male patient with pigmented gingiva in mandible and maxilla; (4) A 14-year-old female needing exposure of maxillary right canine for bracket bonding; and (5) A 25-year-old female patient who has a gingival maxillary frenum with a nodule. The treatment plan for all the patients was laser surgery with diode laser at 980 nm, in continuous mode. Results: All the patients experienced normal healing process with no postoperative complications. Favorable outcomes of laser surgery were observed on follow-up sessions. Conclusion: Considering the versatility of the 980 nm diode laser in oral soft tissue surgeries and the advantages of laser surgery, this study suggests the use of 980 nm diode laser in this regard.

Abstract
INTRODUCTION Inadequate vestibular depth results in poor plaque control owing to an insufficient width of keratinized gingiva. Vestibuloplasty provides the necessary vestibular depth and can be performed either with a scalpel, electrocautery or lasers. AIM To evaluate the patient perceptions related to pain and discomfort on the 1(st), 3(rd) and the 7(th) day post vestibuloplasty and also assess the healing outcomes related to the treatment of inadequate vestibular depth either with the diode laser or the scalpel. MATERIALS AND METHODS Twenty patients who had inadequate vestibular depth and required vestibuloplasty were assigned randomly to undergo the procedure either with the scalpel or the laser. The data obtained was analysed for intergroup comparison with an independent paired t-test and intragroup comparison was determined by a paired t-test. RESULTS Intragroup comparison within the laser group for VAS scores of pain and discomfort within all the reported days exhibited a significant difference (p<0.05). Inter group comparison revealed that the patients in the laser group had lower VAS cores for pain and discomfort compared to the scalpel group (p<0.05). Analysis of the three pointer scale for healing revealed that the patients in the laser group exhibited better healing outcomes on the 1(st), 3(rd) and the 7(th) day compared to the scalpel group. CONCLUSION Observations from the study highlight the opinion that laser can be a safe and effective alternative to traditional vestibuloplasty performed with the scalpel.

Abstract
INTRODUCTION Lasers have made tremendous progress in the field of dentistry and have turned out to be crucial in oral surgery as collateral approach for soft tissue surgery. This rapid progress can be attributed to the fact that lasers allow efficient execution of soft tissue procedures with excellent hemostasis and field visibility. When matched to scalpel, electrocautery or high frequency devices, lasers offer maximum postoperative patient comfort. METHODS Four patients agreed to undergo surgical removal of benign lesions of the oral cavity. 810 nm diode lasers were used in continuous wave mode for excisional biopsy. The specimens were sent for histopathological examination and patients were assessed on intraoperative and postoperative complications. RESULTS Diode laser surgery was rapid, bloodless and well accepted by patients and led to complete resolution of the lesions. The excised specimen proved adequate for histopathological examination. Hemostasis was achieved immediately after the procedure with minimal postoperative problems, discomfort and scarring. CONCLUSION We conclude that diode lasers are rapidly becoming the standard of care in contemporary dental practice and can be employed in procedures requiring excisional biopsy of oral soft tissue lesions with minimal problems in histopathological diagnosis.

Abstract
Background To examine the process of epithelial reparation in a surgical wound caused by diode laser. Material and Methods An experimental study with 27 Sprage-Dawley rats was undertaken. The animals were randomly allocated to two experimental groups, whose individuals underwent glossectomy by means of a diode laser at different wattages, and a control group treated using a number 15 scalpel blade.
The animals were slaughtered at the 2nd, 7th, and 14th day after glossectomy. The specimens were independently studied by two pathologists (blinded for the specimens’ group). Results At the 7th day, re-epithelisation was slightly faster for the control group (conventional scalpel) (p=0.011). At the 14th day, complete re-epithelization was observed for all groups. The experimental groups displayed a pseudoepitheliomatous hyperplasia. Conclusions It is concluded that, considering the limitations of this kind of experimental studies, early re-epithelisation occurs slightly faster when a conventional scalpel is used for incision, although re-epithelisation is completed in two weeks no matter the instrument used. In addition, pseudoepitheliomatous hyperplasia is a potential event after oral mucosa surgery with diode laser. Knowledge about this phenomenon (not previously described) may prevent diagnostic mistakes and inadequate treatment approaches, particularly when dealing with potentially malignant oral lesions. Key words:Diode laser, animal model, oral biopsy, oral cancer, oral precancer, pseudoepitheliomatous hyperplasia.

Abstract
PURPOSE OF THE STUDY To evaluate whether laser has got any advantage over electrocautery in performing gingivectomy procedure. METHOD This was randomized split mouth prospective study where 17 patients having symmetrical gingival hyperplasia were treated with electrocautery and laser on each side. Intra- and postoperative parameters assessed were duration of surgery, bleeding, tissue sticking, postoperative pain and healing. The results were statistically analyzed and compared. RESULT There were 7 Females and 10 Males with a mean age of 28.2 ± 11.6 years. The mean time taken on the laser and electrocautery was 16 (±8.05) and 16.7 min (±9.86) respectively and the difference was not significant. On laser side, there was no bleeding in 3 (17.6%) and self limiting in 14 patients (82.4%) whereas electrocautery side, there was no bleeding in 2 (11.8%) and self limiting in 15 patients (88.2%). Both electrocautery and laser were comparable regarding ease of use during gingivectomy procedure. Charring was observed on both sides although there was more charring on the laser side. Fibrinous slough was present on both sides at 24 h. Difference in healing was not significant at various time intervals. There were no significant difference in postoperative pain experienced by the patients among the laser and cautery group at different time intervals. CONCLUSION Both techniques with proper adhesion to safeguards, can be used to remove gingival overgrowth with equal efficiency and wound healing capacity. There is no advantage of diode laser over electrocautery in performing gingivectomy.

Abstract
Background Genital warts caused by human papillomavirus (HPV) infection are the most common sexually transmitted disease leading to anogential lesions. Although the laser therapy has been shown to be effective in a number of conditions, the use of laser diode vaporization in urological applications and the understanding on its effectiveness as a treatment for various urological conditions is limited. Therefore, the aim of this study was to evaluate the efficacy of diode laser vaporization as a treatment for genital lesions. Methods Patients presenting with genital lesions at the urology outpatient clinic at Coronel Mota Hospital, between March 2008 and October 2014, were enrolled into the study. Data collected included age, gender, duration of the lesion, site of the lesion and numbers of the lesions, length of follow-up, recurrence of lesions after treatment and whether there were any complications. Results A total of 92 patients were enrolled in the study; 92.4% (n = 85) male; mean age (± SD) 27.92 ± 8.272 years. The patients presented with a total of 296 lesions, with a median of 3 lesions each, including penis (n = 78), urethra (n = 4) lesions, and scrotum (n = 2) lesions. Lesions ranged in size from 0.1 to 0.5 cm2, most commonly 0.3 cm2 (n = 38; 41.3%), 0.4 cm2 (n = 21; 22.8%) or 0.5 cm2 (n = 20; 21.7%). Patients most commonly reported that they had their lesions for a duration of 12 (n = 29; 31.5%) or 6 months (n = 23; 25.0%). Eighteen patients (19.6%) had a recurrence after their 1st/conventional treatment. There were no incidences of post–operative infection or complications from the laser diode vaporization. Conclusions Laser diode vaporization can be considered as an alternative method for treating genital lesions in urology, with satisfactory results in terms of pain, aesthetic and minimal recurrence.

Abstract
Hyperpigmentation of gingiva becomes more pronounced if it is associated with “gummy smile.” Correction of gummy smile and depigmentation together are key to complete patient satisfaction. An 810 nm (1.5 W, pulsed) GaAlAs diode laser was used to achieve the desired results in a 22-year-old female patient. The 6-month follow-up results showed excellent color and contour of the gingiva. Mere depigmentation without correcting gummy smile may look cosmetically good but esthetically unacceptable. Diode laser was used as it is known to be an excellent tool as compared with other conventional surgical procedures in terms of patient and operator comfort.

Abstract
Objective: To evaluate the safety and efficacy of an 810-nm diode laser for treatment of benign oral soft tissue lesions. Materials and Methods: Treatment with the 810-nm diode laser was applied to a group of eighteen patients with pathological frenulum and epulis fissuratum; five patients with oral lichen planus, oral leukoplakia, and mucous membrane pemphigoid; and four patients with pyogenic granuloma. Results: Although the conventional surgery wound heals in a fairly short time, in the present study, the simple oral soft tissue lesions healed within two weeks, the white and vesiculobullous lesions healed completely within six weeks, and the pyogenic granuloma lesions healed within four weeks. Any complication was treated by using the 810-nm diode laser. Conclusions: Patient acceptance and satisfaction, without compromising health and function, have been found to be of a high degree in this present study. Thus, we can say that the use of the 810-nm diode laser may indeed be the best choice in oral soft tissue surgery.

Abstract
PURPOSE This study was undertaken to compare wound healing following incisions with either a scalpel, CO(2) laser or Er,Cr:YSGG laser in Guinea pig oral mucosa. MATERIALS AND METHODS Three types of wounds were randomly introduced with either a stainless steel scalpel, CO(2) laser or Er,Cr:YSGG laser in the buccal mucosa of each of 22 Guinea pigs. Four Guinea pigs were sacrificed on day 1, day 3 and day 5 post-surgery. Five Guinea pigs were sacrificed on day 7 and day 14 post-surgery. Biopsy samples from each oral mucosa wound were examined and the expression of TNF-α and TGF-ß1 was determined by immunohistochemical staining. RESULTS At day 3 post-surgery, the histological pattern of the healing process was similar in the scalpel and Er,Cr:YSGG laser wounds and there were more ulcerations present in the CO(2) laser wounds than in the scalpel and Er,Cr:YSGG laser wounds. The level of TNF-α expression was twice in the laser wounds that in the scalpel wounds. A higher level of TGF-β1 expression was seen at day 7 post-surgery and a lower level at day 14 post-surgery in the CO(2) laser wounds than in the scalpel and Er,Cr:YSGG laser wounds. CONCLUSIONS The Er,Cr:YSGG laser has many advantages for oral surgery due to a low inflammatory response and minimal damage of the tissue. Although a CO(2) laser has better hemostatic ability, its use causes greater tissue damage than a scalpel and Er,Cr:YSGG laser. However, further larger studies would be needed before fully endorsing its widespread use.

Abstract
Since the diode laser is a good compromise for the daily use in dental offices, finding usage in numerous dental indications (e.g., surgery, periodontics, and endodontics), the minimization of the collateral damage in laser surgery is important to improve the therapeutical outcome. The aim of this study was to investigate the effect of water/air cooling on the collateral thermal soft tissue damage of 980-nm diode laser incisions. A total of 36 mechanically executed laser cuts in pork liver were made with a 980-nm diode laser in micropulsed mode with three different settings of water/air cooling and examined by histological assessment to determine the area and size of carbonization, necrosis, and reversible tissue damage as well as incision depth and width. In our study, clearly the incision depth increased significantly under water/air cooling (270.9 versus 502.3 μm-test group 3) without significant changes of incision width. In test group 2, the total area of damage was significantly smaller than in the control group (in this group, the incision depth increases by 65 %). In test group 3, the total area of damage was significantly higher (incision depth increased by 85 %), but the bigger part of it represented a reversible tissue alteration leaving the amount of irreversible damage almost the same as in the control group. This first pilot study clearly shows that water/air cooling in vitro has an effect on collateral tissue damage. Further studies will have to verify, if the reduced collateral damage we have proved in this study can lead to accelerated wound healing. Reduction of collateral thermal damage after diode laser incisions is clinically relevant for promoted wound healing.
