[PMID: 38148873 PMCID: PMC10750110 DOI: 10.1016/j.jdsr.2023.11.002] [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: 08/07/2023] [Revised: 11/01/2023] [Accepted: 11/14/2023] [Indexed: 12/28/2023] Open
Abstract
Lasers have numerous advantageous tissue interactions such as ablation or vaporization, hemostasis, bacterial killing, as well as biological effects, which induce various beneficial therapeutic effects and biological responses in the tissues. Thus, lasers are considered an effective and suitable device for treating a variety of inflammatory and infectious conditions of periodontal disease. Among various laser systems, the Er:YAG laser, which can be effectively and safely used in both soft and hard tissues with minimal thermal side effects, has been attracting much attention in periodontal therapy. This laser can effectively and precisely debride the diseased root surface including calculus removal, ablate diseased connective tissues within the bone defects, and stimulate the irradiated surrounding periodontal tissues during surgery, resulting in favorable wound healing as well as regeneration of periodontal tissues. The safe and effective performance of Er:YAG laser-assisted periodontal surgery has been reported with comparable and occasionally superior clinical outcomes compared to conventional surgery. This article explains the characteristics of the Er:YAG laser and introduces its applications in periodontal surgery including conventional flap surgery, regenerative surgery, and flapless surgery, based on scientific evidence from currently available basic and clinical studies as well as cases reports.

Abstract
Aim: The study aims to assess the efficacy of rose bengal (RB)-mediated antimicrobial photodynamic therapy (a-PDT) as an adjunct to scaling and root planing in the management of chronic periodontitis patients in terms of clinical parameters like gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and microbiological parameters like total microbial count, total red complex organism count, Porphyromonas gingivalis count, Treponema denticola count, and Tannerella forsythia count. Materials and Methods: In this randomized controlled clinical trial, a total of 30 patients were recruited who met the inclusion criteria. The participants were randomly allocated into group A with scaling and root planning (SRP) alone and group B with SRP + a-PDT. The clinical and microbiological parameters were measured at baseline and at 3-month follow-up. Intergroup and intragroup comparisons were performed using independent t test and paired t test, respectively. Value of p < 0.05 was considered as statistically significant. Results: At 3-month follow-up, group B treated with SRP + a-PDT showed statistically significant reduction in GI (0.58 ± 0.20) and PPD (1.81 ± 0.32 mm), gain in CAL (0.73 ± 0.04 mm), and reduction in total microbial count [2.80 ± 0.08 × 104 colony forming unit (CFU)], total red complex count (0.29 ± 0.14 × 102 CFU), P. gingivalis count (0.43 ± 0.13 × 102 CFU), T. denticola count (0.61 ± 0.04 × 102 CFU), and T. forsythia count (0.59 ± 0.04 × 102 CFU) as compared with group A (p < 0.05). Conclusion: RB-mediated a-PDT as an adjunct to SRP was significantly more effective in improving GI, PPD, and CAL and in reducing microbial count as compared with SRP alone in the management of chronic periodontitis.

Abstract
Objectives: Photochemical systems are frequently recommended as an adjuvant treatment option in peri-implantitis therapy. The aim of the present study was to evaluate the efficacy of these treatment options, as well as a novel curcumin-based option, in a biofilm model on implants. Methods: Eighty dental implants were inoculated with an artificial biofilm of periodontal pathogens and placed in peri-implant pocket models. The following groups were analyzed: I, photodynamic therapy (PDT); II, PDT dye; III, curcumin/DMSO + laser; IV, curcumin/DMSO only; V, dimethyl sulfoxide (DMSO) only; VI, photothermal therapy (PTT); VII, PTT dye; VIII, control. After treatment, remaining bacterial loads were assessed microbiologically using quantitative real-time polymerase chain reaction analysis. Results: The PDT, PTT, and DMSO treatment methods were associated with statistically significant (p < 0.05) improvements in germ reduction in comparison with the other methods and the untreated control group. The mean percentage reductions were as follows: I (PDT) 93.9%, II (PDT dye) 62.9%, III (curcumin/DMSO + laser) 74.8%, IV (curcumin/DMSO only) 67.9%, V (DMSO) 89.4%, VI (PTT) 86.8%, and VII (PTT dye) 66.3%. Conclusions: The commercially available PDT and PTT adjuvant treatment systems were associated with the largest statistically significant reduction in periopathogenic bacteria on implant surfaces. However, activation with laser light at a suitable wavelength is necessary to achieve the bactericidal effects. The use of curcumin as a photosensitizer for 445 nm laser irradiation did not lead to any improvement in antibacterial efficacy in comparison with rinsing with DMSO solution alone.

Abstract
Scaling and root planing (SRP) removes bacterial plaque, calculus, and associated microorganisms from the surface of the tooth and the surrounding soft tissue. While complete eradication of pathogenic microbes is impossible, gross removal can lower the microbial load, which in turn reduces inflammation and contributes to positive clinical outcomes. Instrumentation in limited-access anatomic areas like furcation, grooves, deep pockets, concavities, and distal molar areas is technically demanding with traditional mechanical debridement. However, emerging advanced systems such as lasers with bactericidal and detoxification effects offer the benefit of reaching limited-access areas that traditional SRP cannot reach. A digitized search was done on PubMed, Embase, Medline, and Google Scholar using the keywords "lasers", "periodontal therapy", "scaling", and "root planing". Upon screening and reviewing, the shortlisted articles comprised narrative reviews, systematic reviews, randomized controlled trials, comparative studies, split-mouth studies, case series, and reports of non-surgical laser therapy and lasers as an adjunct to SRP. This review presents a comprehensive comparative evaluation of different laser modalities utilized in non-surgical periodontal treatment in contrast to standard SRP, rather than an exhaustive article review. It delves into the history and development of lasers, highlighting key advancements made in the realm of periodontics and dental care. This review includes an elucidation of the theory behind laser operation, along with an exploration of its intrinsic characteristics and breakdown of the various types of lasers that are currently available, and an examination of existing literature in both present and historical contexts regarding the comparison of various types of lasers with traditional periodontal treatment.

Abstract
Tongue-tie is a continuation of the lingual frenum that is attached to the tip of the tongue. It is a congenital oral anomaly that could restrict tongue movements, caused by a lingual frenum a membrane that originates from the floor of the mouth to the bottom of the tongue that is too thick and short, which limits the natural ability of the tongue to move and function. The tongue is an auxiliary organ that facilitates speaking, mastication, and deglutition. This condition may result in several difficulties including chewing, breastfeeding, speech, and pronunciation of particular words, as well as possessing social and mechanical consequences. Ankyloglossia can be seen in young age groups. The use of lasers has increased in dentistry in recent years. However, in oral and maxillofacial surgery, the use of lasers has been largely restricted to soft tissues, and less focus is placed on the use of hard tissues. Carbon dioxide (CO2) lasers, erbium-doped yttrium aluminum garnet (Er: YAG) lasers, and Er, the erbium, chromium: yttrium: scandium gallium-garnet (Cr: YSGG) lasers are among the several types of lasers that have been utilized in dentistry for correction of soft tissues as well as for hard tissues.

Abstract
OBJECTIVES Periodontal debridement involves conventional scaling and root planing (SRP) along with variant forms of adjunctive therapies. In the present clinical trial, we investigated if the adjunctive use of HybenX gel or diode laser along with SRP could provide a favorable outcome for the treatment of chronic periodontitis. MATERIALS AND METHODS The present study involved 60 subjects diagnosed with chronic periodontitis who were randomly assigned as test groups (laser or HybenX) or control group (SRP alone). The primary outcomes of the clinical trial were pocket probing depth (PPD) and clinical attachment level (CAL), which was evaluated at baseline and at third-month time interval. Additionally, secondary outcomes included estimation of reduction in inflammatory mediators interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) in gingival crevicular fluid using enzyme-linked immunosorbent assay at baseline and third-month intervals. STATISTICAL ANALYSIS Normality determination was checked using Shapiro-Wilk test. Since the data was not normally distributed, nonparametric tests were applied. The comparison of clinical parameters between the groups was analyzed with Kruskal-Wallis test. Wilcoxon sign rank test was used to compare the pairwise comparison of clinical parameters among the groups from baseline to third-month follow-up. The inflammatory mediators at various time points were compared using a One-way analysis of variance test, and the inflammatory mediators in each study group were compared using a paired t-test. RESULTS Both the test groups demonstrated a decrease in PPD and CAL. However, the HybenX group exhibited statistically significant reduction at the end of the third-month study interval compared to the laser group and SRP alone. Further, the secondary outcome IL-1β and TNF-α analysis exhibited statistically significant reduction in all the groups posttherapy. CONCLUSION The adjunctive application of HybenX gel yielded an advantage compared to laser and SRP for the treatment of chronic periodontitis. CLINICAL RELEVANCE Adjunctive use of the oral tissue desiccant (HybenX gel) combined with SRP improved the periodontal pocket disinfection process and enhanced tissue healing devoid of adverse effects.

Biofilm removal from Difficult-to-Reach places via secondary cavitation within a constrained geometry mimicking a Periodontal/Peri-Implant pocket. ULTRASONICS SONOCHEMISTRY 2024; 104:106832.

Abstract
Biofilm removal from the apical region of the periodontal or peri-implant pocket, which is very difficult to achieve with mechanical instruments, is a major unresolved issue in dentistry. Here, we propose the use of photoacoustically induced streaming and secondary cavitation to achieve superior cleaning efficacy in the apical region of the periodontal and peri-implant pocket. We have used a prefabricated narrow wedge system that mimics the consistency of periodontal and peri-implant pockets of both healthy and severely inflamed tissue. We studied the effect of single-pulse modality Er:YAG on Pseudomonas aeruginosa biofilm removal. We used different laser energies, fiber-tip positions, and laser treatment durations. The cleaning process was monitored in real-time with a high-speed camera after each individual laser pulse application. The obtained results suggest that biofilm cleaning efficacy in a difficult-to-reach place in healthy model tissue is directly related to the onset of secondary cavitation bubble formation, which correlates with a significant improvement of biofilm removal from the apical region of the periodontal or peri-implant pocket. In comparison to the healthy tissue model, the laser energy in inflamed tissue model had to be increased to obtain comparable biofilm cleaning efficacy. The advantage of photoacoustic cavitation compared to other methods is that laser-induced cavitation can trigger secondary cavitation at large distances from the point of laser application, which in principle allows biofilm removal at distant locations not reachable with a laser fiber tip or other mechanical instruments.

Abstract
BACKGROUND Periodontitis is a microbially induced disease destroying structures anchoring teeth to jaw bones. Although metronidazole in combination with spiramycin is the effective conventional treatment of stage III grade C periodontitis, it has several systemic side effects. Laser therapy is widely used nowadays as an adjunct to scaling and root planing (SRP) to modulate inflammatory host response and eradicate microbes, due to bactericidal and detoxifying effects. Since microbiological analysis is one of the diagnostic methods identifying periodontal risk; our research aimed to investigate the efficacy of intra-pocket application of diode laser (980 nm) versus antibiotic therapy in enhancing clinical and microbiological parameters in stage III grade C periodontitis. METHODS A randomized controlled clinical trial was conducted on fifty patients with stage III grade C periodontitis, divided equally into two groups. We managed test group by SRP with intra-pocket application of diode laser (980 nm) and the control group by SRP with systemic antibiotic administration (spiramycin and metronidazole). Then, we measured periodontal pocket depth (PPD) and clinical attachment loss (CAL) for both groups, before treatment (baseline), four and twelve weeks after. Moreover, we collected gingival crevicular fluid from both groups at baseline, four and twelve weeks after treatment and analyzed by real-time polymerase chain reaction to detect the relative count of Aggregatibacter actinomycetemcomitans and Porhyromonas gingivalis. RESULTS Compared to baseline, all assessed clinical and microbiological parameters attested improvement at the end of the study period in each group individually with no significant difference between the two studied groups. Although, at twelve weeks, flare up of bacterial levels was detected with systemic antibiotic administration. CONCLUSION Laser therapy can be considered as an effective treatment modality in stage III grade C periodontitis, avoiding the systemic antibiotic side effects and solving the recurrence problems due to bacterial resistance by long term usage.

Abstract
INTRODUCTION The primary goal of periodontal therapy is to arrest the inflammatory disease process which is done by non-surgical and surgical therapies in order to reduce the microorganisms. The outcome of periodontal therapy may not reveal the desired results owing to inaccessible areas for instrumentation, pathogenicity, resistance of the microorganisms, or even due to compromised host response to the treatment. Thus, adjunctive laser therapy has been proposed as a novel treatment modality in the treatment of periodontal disease. Aim: The aim of this study was to clinically evaluate the effect of a 980 nm diode laser (DEN10B; Wuhan Gigaa Optronics Technology Co., Ltd., Wuhan, China) therapy as an adjunct to scaling and root planing in patients with chronic periodontitis and type II diabetes. METHODS Twenty patients were divided into two groups in a split-mouth study design. Group I (Control) comprised mechanical debridement alone and Group II (test) comprised mechanical debridement followed by adjunctive laser therapy. The clinical parameters were recorded at baseline, six weeks, and three months, and the results were analyzed. RESULTS There was a significant improvement in gingival and plaque index in the test group. Though there was no significant improvement in probing pocket depth and clinical attachment, the results in the test group were superior relative to the control group. CONCLUSION Non-surgical periodontal therapy with adjunctive use of diode laser is effective in the management of generalized chronic periodontitis in patients with type II diabetes which led to a significant reduction in plaque score, gingival index score, probing pocket depth, and gain in clinical attachment level.

Abstract
OBJECTIVES To systematically evaluate randomised controlled trials (RCTs) on whether adjuvant application of antimicrobial photodynamic therapy (aPDT) through the technique of irradiation in the external region of the periodontal pocket with optic-fibre tip offers benefits to scaling and root planning (SRP). METHODS Five databases were searched by two independent reviewers according to pre-specified eligibility criteria up to April 2023. No restrictions regarding date of publication, language and minimum follow-up period were imposed. The Cochrane Collaboration's Risk of Bias tool (RoB 2.0) was used for quality appraisal and Grading of Recommendations, Assessment, Development and Evaluation for assessing the certainty of evidence. RESULTS A total of 1388 publications were identified and reviewed for eligibility. Four of them fulfilled the inclusion criteria. The sample consisted of a total of 83 patients with periodontitis. In these, 330 periodontal sites were evaluated. The clinical findings of the majority of the included studies demonstrated that patients who received the association of aPDT + RAR with the protocol evaluated here, obtained clinical results similar to patients who received only the SRP alone. In none of the evaluated RCTs, clinical advantages were observed that would categorise this aPDT protocol as superior to conventional treatment. CONCLUSION Applying aPDT after SRP with external irradiation of the periodontal pocket does not seem to result in any clinical benefit compared to the use of SRP alone in patients with periodontitis.

Photobiomodulation effects of pulsed and continuous wave near-infrared laser on the proliferation and migration of human gingival fibroblasts: An in vitro study. Photochem Photobiol 2024; 100:225-232. [PMID: 37254280 DOI: 10.1111/php.13816] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 05/06/2023] [Accepted: 05/17/2023] [Indexed: 06/01/2023]
Abstract
There are limited data on comparison of pulsed and continuous wave in photobiomodulation therapy (PBM). This study aimed to investigate the effect of PBM with 980 nm laser in pulsed and continuous wave on the proliferation and migration of human gingival fibroblasts (HGF) cells. Cultured HGF were divided into three main groups: (1) irradiated in pulsed mode (frequencies of 50 and 25 KHz; energy densities of 3 and 5 J/cm2 ), (2) irradiated in continuous mode (energy densities of 3.2 and 5.2 J/cm2 ), and (3) no irradiation as control group. HGF proliferation rate was measured by MTT assay at 24, 48, and 72 h post irradiation. In addition, HGF migration rate was measured by scratch test at 24 h post PBM. At 24 h, the group received continuous irradiation at 5.2 J/cm2 showed significantly higher proliferation compared with the control group (p = 0.012). At 48 and 72 h, the groups received continuous, and 50 Hz pulsed irradiation at energy densities of 5.2 and 5 J/cm2 respectively, had significantly higher HGF proliferation rates compared to the control (p < 0.05). Only the continuous irradiations were effective in significant increase of the cell migration. In conclusion, continuous PBM at energy density of 5.2 J/cm2 showed promising effect on HGF proliferation and migration.

Abstract
INTRODUCTION Various rotary and mechanical instruments are used in conventional oral surgery for osteotomies. Despite the implementation of effective cooling systems, it is difficult to prevent thermal damage to the adjacent bone caused by heat generated during the procedure. A smear layer forms on the surface, which can impede the interaction of blood elements with the underlying tissue, resulting in a delayed healing process.

Application of Different Wavelengths of LED Lights in Antimicrobial Photodynamic Therapy for the Treatment of Periodontal Disease. Antibiotics (Basel) 2023; 12:1676.

Abstract
Therapeutic light has been increasingly used in clinical dentistry for surgical ablation, disinfection, bio-stimulation, reduction in inflammation, and promotion of wound healing. Photodynamic therapy (PDT), a type of phototherapy, has been used to selectively destroy tumor cells. Antimicrobial PDT (a-PDT) is used to inactivate causative bacteria in infectious oral diseases, such as periodontitis. Several studies have reported that this minimally invasive technique has favorable therapeutic outcomes with a low probability of adverse effects. PDT is based on the photochemical reaction between light, a photosensitizer, and oxygen, which affects its efficacy. Low-power lasers have been predominantly used in phototherapy for periodontal treatments, while light-emitting diodes (LEDs) have received considerable attention as a novel light source in recent years. LEDs can emit broad wavelengths of light, from infrared to ultraviolet, and the lower directivity of LED light appears to be suitable for plaque control over large and complex surfaces. In addition, LED devices are small, lightweight, and less expensive than lasers. Although limited evidence exists on LED-based a-PDT for periodontitis, a-PDT using red or blue LED light could be effective in attenuating bacteria associated with periodontal diseases. LEDs have the potential to provide a new direction for light therapy in periodontics.

Abstract
OBJECTIVES The aim of this study was to investigate whether the use of adjunctive Nd:YAG (1064 nm) laser irradiation to full-mouth scaling and root planing (FM-SRP) may offer additional benefit in the systemic inflammatory status of the patient, as depicted in a variety of systemic biomarkers over FM-SRP alone, up to 12 months after treatment. MATERIALS AND METHODS A total of 60 otherwise healthy stage III/IV periodontal patients were equally distributed in 3 groups. The control group received FM-SRP. In laser A group, 1 week after FM-SRP, Nd:YAG laser irradiation was delivered in periodontal pockets with PD ≥ 4 mm using specific settings (3 W, 150 mJ, 20 Hz, 100 μs). In laser B group Nd:YAG laser irradiation was delivered twice, 1 week after FM-SRP and 1 week later with different settings compared to laser A (2 W, 200 mJ, 10 Hz, 100 μs). RESULTS A significant reduction (p = 0.038) of IL-1β serum levels at the 6-month time point was observed for laser A group. IL-6 was found statistically significantly increased (p = 0.011) in the control group at the 6-week time point, whereas no difference was reported for the laser-treated groups (laser A, laser B). CONCLUSIONS The adjunctive use of Nd:YAG laser irradiation, prevented from IL-6 increase after FM-SRP, 6 weeks after treatment. Similarly, Nd:YAG laser irradiation (3 W, 150 mJ, 20 Hz,100 μs) was associated with significantly lower IL-1β levels, 6 months post-operatively. CLINICAL RELEVANCE Additional Nd:YAG laser application to FM-SRP may provide a potential beneficial effect on systemic inflammation. TRIAL REGISTRATION NUMBER ISRCTN26692900.

Abstract
BACKGROUND This study evaluated the effectiveness of a novel pocket therapy (Er:YAG laser-assisted comprehensive periodontal pocket therapy [Er-LCPT]) for residual pocket treatment, compared with conventional mechanical treatment alone, in a randomized controlled clinical trial. METHODS Two sites in 18 patients having residual periodontal pockets of ≥5 mm depth, extant following initial active therapy, or during supportive therapy, were randomized into two groups in a split mouth design: the control group received scaling and root planing (SRP) by curette, and the test group received Er-LCPT using curette and laser. With Er-LCPT, after root debridement, inflamed connective tissue on the inner gingival surface and on the bone surface/within extant bone defects was thoroughly debrided. Furthermore, removal of proximate oral epithelium and coagulation of the blood clot in the pocket entrance were performed with laser. Clinical parameters were evaluated, before and after treatment, through 12 months. RESULTS Both groups showed significant improvements in clinical parameters. With Er-LCPT, pocket debridement was thoroughly and safely performed, without any adverse side effects and complications, and favorable healing was observed in most of the cases. At 12 months, Er-LCPT demonstrated significantly higher probing pocket depth reduction (2.78 mm vs. 1.89 mm on average; p = 0.012, Wilcoxon signed-rank test), clinical attachment gain (1.67 mm vs. 1.06 mm; p = 0.004) as primary outcomes, and reduced BOP value (0.89 vs. 0.56; p = 0.031), compared with SRP alone. CONCLUSION The results of this study indicate that Er-LCPT is more effective for residual pocket treatment, compared with SRP alone.

Abstract
Background and objective: Some studies support the superiority of diode laser gingivectomy to scalpel surgery and nonsurgical treatments. However, a systematic review on this topic is lacking. This study aimed to compare gingivectomy with diode laser versus the conventional scalpel surgery and nonsurgical periodontal therapy (NSPT) in the treatment of orthodontic treatment-induced gingival enlargement (GE). Materials and methods: In this systematic review, an electronic search of the relevant literature was conducted in Web of Science, Medline/PubMed, Scopus, Cochrane Central Register of Controlled Trials, and ProQuest with no language restriction. Randomized clinical trials published between 1985 and 2020 on comparative treatment of orthodontic treatment-induced GE by diode laser gingivectomy and scalpel surgery or NSPT regarding intraoperative and postoperative bleeding and/or pain were included. Risk of bias was assessed by the Cochrane 1 tool. Results: Of the initially retrieved 288 articles, 40 were duplicates and excluded; 236 articles were excluded following title and abstract screening, and 5 others were excluded following full-text assessment. Finally, 7 studies underwent systematic review. In the risk-of-bias assessment, 5 studies scored 2, and 2 studies scored 3 out of 6. Intraoperative and postoperative bleeding and pain were found to be significantly lower in the laser group. Conclusions: Within the limitations of this systematic review and with respect to the quality of evidence, the present results revealed lower level of pain and bleeding in diode laser gingivectomy compared with the conventional scalpel surgery and NSPT for treatment of orthodontic treatment-induced GE.

Abstract
Introduction As is known, periodontal pathogens and their products as well as inflammatory mediators produced in periodontal tissues might enter the bloodstream, causing systemic effects and/or contributing to systemic diseases. Aim To evaluate the effect of diode lasers on the incidence of bacteremia associated with ultrasonic scaling and its clinical efficacy as an adjunct to scaling in the treatment of moderate periodontitis. Result The use of diode laser is more effective in killing or detoxifying periodontopathic bacteria such as P. gingivalis associated with chronic periodontitis as compared to ultrasonic alone with ablate bacteria only when it comes in contact with plaque biofilm directly. Conclusion The results of study confirm the previously reported findings that bacteremia is caused by ultrasonic scaling and adjunct use of diode laser with scaling has the potential to reduce the bacteremia associated with ultrasonic scaling alone.

Abstract
Background Although dental implants have demonstrated very high success rates, they are susceptible to complications such as peri-implantitis that can lead to failure. Methods Twenty implants with surfaces grit-blasted using hydroxyapatite and acid-etched were randomly divided into four groups (five in each group). Three groups were assigned to laser treatments: Group I (erbium, chromium-doped: yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser), Group II (650-nm diode laser), and Group III (808-nm diode), and one control group, Group IV. The surface roughness parameters (roughness average(Ra) and root mean square roughness(Rq)) were measured using a non-contact optical profilometer and scanning electron microscope to evaluate the surface topography after the laser treatments. Results Significant differences were observed between the laser groups regarding the surface roughness Ra (3.56±0.26, 3.45±0.19, 3.77±0.42, pc=0.0004, pe=0.0002, pf=0.001) and Rq values (4.49±0.34, 4.35±0.26, 4.72±0.56, pc=0.0007, pe=0.0006, pf=0.002) and the control group (2.81±0.10; 3.57±0.19). However, no significant difference was observed between the different laser treatment modalities. The scanning electron microscope images revealed some morphological changes on the implant surfaces following laser treatment, but no melted morphology was observed. Conclusions The application of Er,Cr:YSGG, 650-nm diode laser, and 808-nm diode did not show melting changes on implant topography. However, some increase in surface roughness was detected. Further studies are recommended to assess the effectiveness of these laser settings on bacterial reduction and osseointegration.

Abstract
Objective: Periodontal instrumentation during supragingival prophylaxis may increase enamel surface roughness, which may lead to increased dental biofilm accumulation and demineralization of the enamel. The aim of this study was to evaluate the changes of the enamel surface profilometrically after the application of different scaler tips used for the professional supragingival prophylaxis. Materials and methods: Forty-eight enamel block samples obtained from extracted human maxillary premolar teeth were prepared and randomly assigned to four different treatment groups. Each treatment group was instrumented by the same clinician with different tools as Group 1: Er:YAG laser chisel tip, Group 2: scaler, Group 3: new generation universal curette; and Group 4: ultrasonic device. Sample surfaces were evaluated with a profilometer before and after instrumentations and after the polishing process. Results: Baseline roughness of the prepared enamel samples was similar between the groups. After instrumentation and polishing, the Er:YAG laser chisel tip revealed the most irregular surface morphology, whereas the new generation curette induced the smoothest surface. Conclusions: New generation universal curette is a promising tool, which can be used safely for supragingival calculus removal without the need for polishing on enamel surfaces.

Abstract
INTRODUCTION Chronic periodontitis is caused by a persistent and expanding interaction between a subgingival pathogenic microbial biofilm and the host immune system. The host's reaction to local factors directly influences the inflammation and bone loss that result from these interactions. Depending on variables like the severity of soft tissue damage and bone loss, treatment options can range from nonsurgical to surgical. Nonsurgical treatments are frequently used as the first-line therapy for inflammatory periodontal disease. In fact, careful scaling and root planing (SRP), a nonsurgical treatment, has been extensively studied and shown to be a highly predictable and effective therapy. According to recent research, using a diode laser (DL) in addition to standard SRP may reduce bacterial count and reinfection significantly. Laser therapy could be helpful in treating periodontal disease because of its antibacterial and detoxifying effects. The goal of this study is to investigate whether using a DL in addition to conventional flap surgery enhances patient outcomes for those with chronic generalized periodontitis. MATERIALS AND METHODS The 12 participants in this split-mouth trial with chronic generalized periodontitis were the main subject of the study. All of them had probing pocket depths (PPDs) of at least 5 mm after the initial phase of treatment. Each patient in the control group (Group A) and test group (Group B) received a conventional flap after being randomly assigned to one of the groups. Group B underwent a conventional flap with a 980 nm DL, whereas those in Group A did not receive any DL therapy. Periodontal pockets in both groups were evaluated at baseline, 45 days, and 90 days after a sub-gingival plaque test. Quantitative real-time polymerase chain reactions were used to examine the presence of red complex organisms in the plaque sample. RESULTS From baseline to 45 days and then to 90 days, clinical attachment loss (CAL), plaque index (PI), and gingival index (GI) all significantly decreased. However, results from 45 days to 90 days were statistically non-significant, with the exception of the GI, where Group B results were significantly different from Group A results from 45 days to 90 days. On the other hand, when a DL was combined with conventional flap surgery in the test group, the quantity of red complex bacteria was significantly decreased. CONCLUSION When DL was used in conjunction with conventional flap surgery, the results showed that CAL, PI, and GI were all significantly reduced while the quantity of red complex bacteria was also significantly decreased.

[PMID: 36978686 PMCID: PMC10044917 DOI: 10.3390/bioengineering10030296] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 02/09/2023] [Accepted: 02/13/2023] [Indexed: 03/02/2023] Open
Abstract
The utilization of lasers has been regarded as a novel technique for the purposes of clinical use in the dental field. Recently, numerous studies have been conducted on the potential applications of laser therapy in endodontics. Moreover, due to their ablation, penetrability, and disinfection capabilities, lasers have performed well with respect to endodontic treatments, including root canal treatment, vital pulp therapy (pulp capping and pulpotomy), dentinal hypersensitivity treatment, and management of dental pain related to pulp and periradicular disease. In particular, the superiorities of laser-aided pulp therapy are emphasized through condensed clinical controlled trials, and histological studies, in this review. Moreover, the ingenious use of laser applications with respect to aiding in the acceleration of root development and the extraction of foreign matters (i.e., broken files and fiber posts) in canals has quickly become the cutting-edge trend of current research. This review offers a summary and discussion of the current literature on all the aforementioned laser applications. Moreover, the characteristics of laser devices, including erbium lasers, neodymium-doped lasers, CO2 lasers, and diode lasers, are detailed and discussed here, providing useful references for laser application in endodontics. We also focus on the different wavelengths with respect to the lasers that are applied in endodontics. High-power lasers perform well as operative instruments; in addition, low-level lasers lead to the regulation of pulp inflammation, and the promotion of pulp healing. This narrative review provides a summary of the advanced applications of lasers in conjunction with various devices in the practice of endodontics, and aims to inspire innovative perspectives on lasers in the context of the treatment of dental diseases, especially pulp diseases, in the future.

Surgical Treatment of Peri-Implantitis Using a Combined Nd: YAG and Er: YAG Laser Approach: Investigation of Clinical and Bone Loss Biomarkers. Dent J (Basel) 2023; 11:dj11030061. [PMID: 36975558 PMCID: PMC10046921 DOI: 10.3390/dj11030061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/13/2023] [Accepted: 02/20/2023] [Indexed: 02/26/2023] Open
Abstract
The current study aimed to investigate the effect of the combined Nd-Er: YAG laser on the surgical treatment of peri-implantitis by evaluating clinical markers and biomarkers of bone loss (RANKL/OPG). Twenty (20) patients having at least 1 implant diagnosed with peri-implantitis were randomly assigned to two groups for surgical treatment. In the test group (n = 10), Er: YAG laser was used for granulation tissue removal and implant surface decontamination, while Nd: YAG laser was employed for deep tissue decontamination and biomodulation. In the control group (n = 10), an access flap was applied, and mechanical instrumentation of the implant surface was performed by using titanium curettes. The following clinical parameters were evaluated at baseline and six months after treatment: Full-mouth Plaque Score (FMPS), Probing Pocket Depth (PPD), Probing Attachment Levels (PAL), recession (REC), and Bleeding on probing (BoP). Peri-implant crevicular fluid (PICF) was collected at baseline and six months for the evaluation of soluble RANKL and OPG utilizing enzyme-linked immunosorbent assay (ELISA). Baseline clinical values were similar for both groups, with no statistical differences between them. The study results indicated statistically significant improvements in the clinical parameters during the 6-month observation period in both groups. More specifically, PPD, PAL, and REC were improved in the test and control groups with no differences in the between-groups comparisons. However, a greater reduction in the BoP-positive sites was noted for the laser group (Mean change 22.05 ± 33.92 vs. 55.00 ± 30.48, p = 0.037). The baseline and six-month comparisons of sRANKL and OPG revealed no statistically significant differences between the two groups. The combined Nd: YAG—Er: YAG laser surgical therapy of peri-implantitis seemed to lead to more favorable improvements in regard to bleeding on probing six months after treatment compared to the conventional mechanical decontamination of the implant surface. None of the methods was found superior in the modification of bone loss biomarkers (RANKL, OPG) six months after treatment.

Adjunctive Nd:YAG laser irradiation in the treatment of stage III/IV periodontitis: a 12-month, randomized, controlled trial. Clin Oral Investig 2023:10.1007/s00784-023-04908-4. [PMID: 36795248 DOI: 10.1007/s00784-023-04908-4] [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: 08/10/2022] [Accepted: 02/03/2023] [Indexed: 02/17/2023]
Abstract
OBJECTIVES The aim of this study was to evaluate the clinical efficacy of the adjunctive use of Nd:YAG laser (1064 nm) to full-mouth scaling and root planning (FMS), in stage III/IV periodontitis patients. MATERIALS AND METHODS Sixty stage III/IV periodontitis patients were randomly assigned to three groups. The control group received FMS, laser 1 group received combined FMS/single Nd:YAG laser irradiation (3 W, 150 mJ, 20 Hz,100 μs), and laser 2 group received combined FMS/double Nd:YAG laser irradiation with 1-week interval (2.0 W, 200 mJ, 10 Hz, 100 μs). PD, CAL, FMPS, GI, FMBS, and GR were evaluated at baseline, 6 weeks, 3, 6, and 12 months after treatment. Patient-reported outcomes were evaluated 1 week after treatment. RESULTS A significant improvement (p < 0.001) for all clinical parameters was observed during the entire study period, with the exception of mean CAL gain for the laser 2 group at 12 months. The percentage of pockets ≤ 4 mm was significantly higher compared to baseline for all groups throughout the study, with no inter-group differences at any time point. Patient-reported analgesic consumption was higher for laser 1 group. CONCLUSIONS The adjunctive use of Nd:YAG laser irradiation was similarly effective to FMS alone, during the entire study period. A slightly higher, though not statistically significant improvement was reported for PD at 6 and 12 months after a single post-FMS application of Nd:YAG laser for pocket epithelium removal and coagulation. CLINICAL RELEVANCE Additional Nd:YAG laser application for sulcular epithelium removal and coagulation may provide minor long-term improvements compared to FMS or laser irradiation for pocket disinfection and detoxification.

Ir J Med Sci 2023; 192:457-466. [PMID: 35138568 DOI: 10.1007/s11845-022-02940-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 02/01/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND The aim of the present study was to evaluate whether different Nd:YAG laser applications as an adjunct to scaling and root planning (SRP) improve the healing response to periodontal therapy in smokers with periodontitis. METHODS This clinical trial included eighty systemically healthy smokers with periodontitis. Patients were randomly allocated to a treatment group: SRP alone (group 1), SRP+low-level laser therapy (LLLT) with Nd:YAG laser (group 2), SRP+pocket debridement with ND:YAG laser (group 3), and SRP+combined pocket debridement and LLLT with Nd:YAG laser (group 4). Gingival index (GI), plaque index (PI), bleeding on probing (%), probing depth (PD), and clinical attachment level (CAL) were recorded, and gingival crevicular fluid (GCF) samples for metalloproteinase-8 (MMP-8) levels were collected at baseline, 1 month and 3 months after treatment. RESULTS There were no significant differences between the treatment groups for the GI, PI, and BOP (%) parameters and MMP-8 levels at any time points (p > 0.05). For moderately deep pockets, PD and CAL reductions were significantly greater in all test groups compared to group 1 (p ˂ 0.05). For deep pockets, these reductions were significantly greater in group 2 and group 4 compared to group 1 (p ˂ 0.05). PD and CAL reductions were generally similar between test groups (p > 0.05) except PD reduction between baseline and 3 months in deep pockets (p ˂ 0.05). CONCLUSIONS The findings of this clinical trial suggest that Nd:YAG laser applications may be beneficial on the healing response of smokers to non-surgical therapy compared to SRP alone.

Abstract
An abnormal and hypertrophied upper labial frenulum (ULF) can cause diastemas, gingival recession, eruption abnormalities, and the onset of carious and periodontal problems in the upper central incisors, as well as aesthetic and functional disorders of the upper lip. The goal of this investigation is to review the evidence on the surgical techniques that are currently available for treating ULF in order to identify the best approach. PubMed, Scopus, Cochrane Library, and Embase were searched for papers that matched our topic from 13 November 2012 up to 22 November 2022 using the following Boolean keywords: "frenulum" and "surgery*". A total of eight articles were selected for the purpose of the review. ULF can be surgically treated using either traditional scalpel surgery or laser surgery. The latter is the better option due to its intra- and post-operative benefits for both the patients and the clinicians, in terms of faster healing, fewer side effects and discomfort, and greater patient compliance. However, a higher learning curve is required for this technique, especially to calibrate the appropriate power of the laser. To date, it is not possible to identify which type of laser achieves the best clinical results for the treatment of ULF.

Abstract
Labial frenectomy is a surgical technique, that aims to remove the frenulum with its attachment to the underlying bone. Frenectomy, is indicated if the frenulum attachment causes midline diastema, gingival recession, hindrance in maintaining oral hygiene, or if it interferes with lip movements and for prosthetic needs. A labial frenectomy can be performed either by the routine scalpel technique, electrocautery, and most recently medical lasers. The aim of this study was to evaluate, whether the laser technique is more effective than the conventional surgical technique, and whether there are differences between the different types of lasers. The scoping review was conducted and prepared on the basis of the indications of the PRISMA guidelines (PRISMA Extension for Scoping Reviews, PRISMA-ScR) of PRISMA checklist, and nine papers were considered admissible to the qualitative analysis for the following outcomes: bleeding during intervention, use of sutures, duration of the intervention, and use of analgesic drugs in the days following the intervention. This review suggests that laser-performed labial frenectomy is faster and offers better intra- and postoperative management; however, due to the limited number of available papers, the final results of the present review are not absolute.

Abstract
AIM The aim of this study was to evaluate combined efficacy of methylene blue mediated antimicrobial photodynamic therapy (a-PDT) using 660 nm diode laser versus Er, Cr: YSGG laser as an adjunct to scaling and root planing on improving the Probing depth (PD), Clinical attachment level (CAL), Plaque Index (PI) and Gingival Index (GI).clinical parameters in Supportive periodontal therapy. MATERIALS AND METHOD In this split-mouth, double-blind, randomized controlled trial, we compared a-PDT versus Er,Cr:YSGG as an adjunct to scaling and root planning (SRP) with SRP alone in Supportive periodontal therapy. A total of 36 subjected were enrolled. In each patient, two quadrants constituted the control group (Group I - Scaling and root planing SRP alone), one site in other quadrant constituted the test group 1 (Group II - SRP followed by application of Er, Cr: YSGG laser), and another site in different quadrant constituted the test group 2 (Group III - SRP followed by antimicrobial Photodynamic therapy using diode laser). The diode laser was operated at a peak power of 70 mW using a 0.6 mm diameter fiber-optic tip. Each site was irradiated with a power density of 28 mW/cm2, for 10 s, thus delivering a total energy of 16.72 J/cm2 per tooth. Whereas, the Er,Cr:YSGG laser's parameters were set to 1 W of power, 10% air, and 15% water. The same procedure was repeated at 1st, 2nd and 3rd week for both the laser therapies. Plaque index (PI), Gingival index (GI), Probing depth (PD,) and Clinical attachment level (CAL) were measured by a single examiner at baseline and 3 months follow up. Inter group analysis of the parameters were done using One-way ANOVA and pairwise comparison was carried out by Tukey's post hoc test. Intra group analysis was performed using Students's paired t test. Statistical significance was set to p < 0.05. RESULTS There were no significant differences between participants for clinical parameters at baseline. PI, GI PD, and CAL significantly improved at 3 months follow up compared to baseline in both the study groups (Group II - SRP + Er,Cr:YSGG, Group III - SRP + a-PDT) with P < 0.05. Adjunctive use of Er,Cr:YSGG laser with SRP showed better clinical outcomes than a-PDT with SRP. CONCLUSION Nonsurgical periodontal therapy of chronic periodontitis using Er, Cr: YSGG, and a-PDT as an adjunct to SRP was significantly more effective than SRP alone in reducing PD, CAL, GI, and PI at 3 months follow up. Adjunctive use of Er,Cr:YSGG laser with SRP showed better clinical outcomes than a-PDT with SRP. However, the long-term positive benefits of the laser therapies are yet unknown and more research with longer follow-ups are required.

Abstract
This study evaluated the effects of diode and erbium lasers, as an adjunct to scaling and root planing (SRP), on clinical and immunological parameters in non-surgical periodontal therapy. In this split-mouth randomized controlled clinical trial, 17 participants with at least one periodontally involved tooth in each quadrant received oral hygiene instruction and full-mouth SRP. At baseline, probing pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and full-mouth plaque index (FMPI) were measured, and gingival crevicular fluid (GCF) sampling was performed. Next, one random quadrant in each participant received 940 nm diode laser (1 W, continuous-wave), and another quadrant received 2780 nm Er,Cr:YSGG laser (1.5 W, 30 Hz) irradiation. The GCF levels of interleukin (IL)-10 and matrix metalloproteinase (MMP)-13 were measured at baseline, and after 2 and 6 months using ELISA. The clinical parameters were also measured. Data were analyzed by repeated measures ANOVA. Significant clinical improvement was noted in all groups (P < 0.05). CAL in the control group was higher at 6 months than 2 months. The increase in IL-10 in erbium group was significantly greater than that in other groups (P < 0.001). The MMP-13 level was significantly lower in laser groups with greater reduction in erbium group (P < 0.001). Application of 940 nm diode and 2780 nm Er,Cr:YSGG lasers as an adjunct to SRP significantly decreased the GCF level of MMP-13, with no significant clinical advantage over SRP monotherapy. Application of 2780 nm Er,Cr:YSGG laser in addition to SRP increased the GCF level of IL-10.Trial registration numbers: IRCT20140318017053N11 and IRCT20140318017053N9.

Abstract
In vitro bacterial elimination using the erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser against periodontopathic bacteria was investigated. Bacterial suspensions of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis were spread on agar plates and the Er,Cr:YSGG laser was applied at 40 mJ pulse energy for durations of 30 s, 60 s, and 90 s. The agar plates were incubated, and growth inhibition zones were assessed. Optimal laser irradiation durations to achieve maximal bacterial elimination were evaluated using laser ablation on the bacterial colonies. The remaining viable bacteria were determined by the colony-forming unit (CFU) counting method. Growth inhibition zones were observed at all irradiation durations for both A. actinomycetemcomitans and P. gingivalis. Mean logarithmic values of CFU/ml after bacterial colony irradiation for 0 s (control), 12 s × 1 lap, 24 s × 1 lap, 48 s × 1 lap, and 24 s × 2 laps were 8.82 ± 0.35, 7.31 ± 0.94, 6.32 ± 0.61, 3.17 ± 2.90, and 0.00, respectively, for A. actinomycetemcomitans and 9.83 ± 0.50, 9.42 ± 0.11, 6.90 ± 1.60, 2.33 ± 3.19, and 0.00 for P. gingivalis. Significant differences were found between the control group and the two irradiated groups 48 s × 1 lap and 24 s × 2 laps (p < 0.05), and also between irradiated groups 12 s × 1 lap and 24 s × 2 laps (p < 0.05). An Er,Cr:YSGG laser with power setting 1.5 W and 30 Hz frequency showed potential for bacterial elimination against A. actinomycetemcomitans and P. gingivalis in vitro. Significant bacterial elimination (> 99.99%) was observed after 48 s of irradiation.

The effectiveness of scaling and root planing with combined application of air polishing and Nd:YAG laser in periodontal pockets of stage III grade C periodontitis patients: a single-blinded randomized clinical trial. Clin Oral Investig 2022; 26:5459-5469. [PMID: 35505199 DOI: 10.1007/s00784-022-04513-x] [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: 02/17/2022] [Accepted: 04/24/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Evaluating the efficiency of combined air polishing and Nd:YAG laser application in addition to scaling and root planning (SRP) in treatment of periodontal pockets of stage III grade C periodontitis patients was the aim of this clinical trial. MATERIALS AND METHODS Twenty-four systemically healthy, stage III grade C periodontitis patients were recruited for this clinical trial. In this split-mouth study, the quadrants were randomly allocated to either SRP with combined air polishing (erythritol/chlorhexidine powder) and Nd:YAG laser (2 W, 200 mJ/pulse, 10 Hz) therapy (test group) or SRP alone (control group). A masked examiner recorded clinical parameters such as plaque index (PI), gingival index (GI), bleeding on probing (%) (BOP %), probing depth (PD), and clinical attachment level (CAL) on periodontal charts at baseline, 1 month and 3 months after treatment. RESULTS The clinical parameters had significantly reduced 1 and 3 months after treatment compared to baseline for both study groups (p < 0.05). Considering PI, GI, and BOP (%) parameters, there were no significant differences between the study groups at any time points (p > 0.05). While PD and CAL reductions were similar in study groups for moderately deep pockets (5 to 6 mm) (p > 0.05), PD and CAL reductions were significantly greater in test group compared to control group for deep pockets (PD ≥ 7 mm) (p < 0.05). CONCLUSIONS The present clinical trial demonstrated that SRP with combined application of air polishing and Nd:YAG laser may be advantageous in sites where mechanical debridement alone cannot access, such as deep pockets in the short term. Long-term, well-designed future studies including clinical, biochemical, and microbiological analyses are needed to determine the effectiveness of this procedure. CLINICAL RELEVANCE SRP with combined application of air polishing and Nd:YAG laser provided more reductions in probing depth and clinical attachment level parameters in deep pockets compared to SRP alone.

Abstract
Lasers are increasingly utilized in the non-surgical treatment of periodontal disease. The aim of the present systematic review with meta-analysis was to investigate the combination use of Nd:YAG and Er:YAG laser therapy in the treatment of severe periodontitis. A systematic review of the literature including searches in PubMed/Medline, Cochrane Library, Google Scholar, and Grey Literature databases, as well as manual searches, was performed until November 1, 2021. Only studies a combination of lasers during non-surgical treatment of pockets ≥ 6mm were included. The eligibility criteria for meta-analysis comprised randomized controlled trials (RCTs) comparing the use of combination laser therapy with/without adjunctive mechanical for the non-surgical management of periodontitis. From 57 initial articles, 6 full-text articles were assessed for eligibility. Two studies were excluded, one study was not a randomized clinical trial (case series), and one study was an in vitro study. Four RCTs were included in the meta-analysis. It was shown that combination of Nd:YAG and Er:YAG may be beneficial for non-surgical periodontal therapy with an additional average reduction in pocket depth and clinical attachment level reported at 1.01 and 0.77 mm respectively when compared to controls. The findings suggest that the combination of Nd:YAG and Er:YAG lasers may lead to additional clinical improvements compared to nonsurgical treatment alone. Future research is needed to substantiate these findings and optimize clinical guidelines including more specific laser protocols. Preliminary data suggest favorable outcomes following the combination of Nd:YAG and Er:YAG lasers for non-surgical periodontal therapy.

Abstract
Laser has been considered to show many favorable characteristics, including wound healing acceleration, hemostasis, biostimulation, and microbial inhibition. Previous studies have investigated the effect of laser treatment during the process of wound healing, with conflicting results. To date, there is still no unified conclusion on the effect and application principle of clinical laser therapy. This study evaluated the incision morphology, wound healing speed, and histological changes in mice oral mucosal wounds excised with diode laser, Er:YAG laser, and cold scalpel. The results showed that compared with the cold scalpel group, laser treatments caused more tissue thermal damage and carbonization, which led to a healing delay. However, lasers also showed some advantages, including hemostasis, regular incision, and immune response mobilization, suggesting that lasers may be beneficial in some specific cases, such as reducing intraoperative accidents and wound tissue laceration and controlling bleeding and postoperative infection. This study provides a theoretical basis for clarifying the effect of laser treatments and their clinical application principle.

Abstract
Background This study aimed to assess the effect of diode laser combined with minocycline hydrochloride in conventional nonsurgical periodontal therapy. Methods Ninety-two patients and 1206 teeth were included in this study. The patients were diagnosed moderate or severe periodontal diseases with the presence of teeth in at least 3 quadrants in the oral cavity. Each patient’s quadrants were randomly divided into three treatment groups as following, Control group: scaling and root planning (SRP); Experimental group 1 (Exp 1): SRP + minocycline hydrochloride; Experimental group 2 (Exp 2): SRP + 809 nm diode laser + minocycline hydrochloride. The minocycline in Exp 1 and Exp 2 was applied once per week, for 4 weeks. Clinical examinations including periodontal probing depth (PD), clinical attachment level (CAL) and bleeding index (BI), and the secretion of inflammatory factor (tumor necrosis factor, TNF-α) was detected by ELISA before and 3, 6 months after the treatments. The differences among these groups were assessed by One-Way ANOVA and Kruskal–Wallis test. P-value < 0.05 was considered significant. Results All the periodontal indexes (PD, CAL and BI) were improved after each treatment and the secretion of TNF-α was reduced for all three groups. In patients with deep periodontal pockets, Exp 2 showed significant improvements in all indexes comparison with Con group and Exp group 1. Conclusions The synergistic effect of SRP and 809 nm diode laser combined with minocycline hydrochloride could play an efficient and reliable effect in the nonsurgical periodontal treatment approach. Trial registration The clinical trial was retrospectively registered in chictr.org.cn with registration ChiCTR2100051708 (01/10/2021).

Abstract
BACKGROUND The purpose of this study was to evaluate the results of adjunctive Er,Cr:YSGG laser therapy with scaling and root planing (SRP) as compared to SRP alone in the treatment of moderate-severe periodontitis. METHODS Fifteen adults (aged 27 to 65 years) with ninety non-adjacent sites probing ≥ 5 mm were treated in split-mouth design with SRP and laser therapy versus SRP alone. Probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL), plaque, and bleeding on probing were collected at baseline, 1, 3, 6, 9, and 12 months. Patient reported outcomes were measured to assess pain, sensitivity and satisfaction. RESULTS Clinical improvements were similar for test and control sites with no statistically significant difference. At twelve months, the average PPD reduced from 6.1mm to 4.2mm for test and 6.2mm to 4.3mm for control sites. GR increased by 0.4mm at test and control sites. CAL increased from 6.8 mm to 5.3mm for test and 6.9mm to 5.5mm for control sites. Clinical outcomes were stratified by baseline PPD ( = 5mm, = 6mm and ≥7mm) and analyzed for number of sites that reduced (≤4mm). No significant difference was observed when the baseline PPD was 5mm or 6mm. Test sites with baseline PPD ≥7mm demonstrated a statistically significant difference in the percentage of reduced sites when compared to controls at 9 (p = 0.001) and 12 months (p = 0.044). CONCLUSIONS Adjunctive Er,Cr:YSGG laser therapy with SRP provides similar clinical improvement in the treatment of moderate-severe periodontitis as SRP alone and may offer some advantage for deeper (≥7mm) pockets.

Abstract
PURPOSE This study aimed to investigate the proper wavelengths for safe levels of light-emitting diode (LED) irradiation with bactericidal and photobiomodulation effects in vitro. METHODS Cell viability tests of fibroblasts and osteoblasts after LED irradiation at 470, 525, 590, 630, and 850 nm were performed using the thiazolyl blue tetrazolium bromide assay. The bactericidal effect of 470-nm LED irradiation was analyzed with Streptococcus gordonii, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis, and Tannerella forsythia. Levels of nitric oxide, a proinflammatory mediator, were measured to identify the anti-inflammatory effect of LED irradiation on lipopolysaccharide-stimulated inflammation in RAW 264.7 macrophages. RESULTS LED irradiation at wavelengths of 470, 525, 590, 630, and 850 nm showed no cytotoxic effect on fibroblasts and osteoblasts. LED irradiation at 630 and 850 nm led to fibroblast proliferation compared to no LED irradiation. LED irradiation at 470 nm resulted in bactericidal effects on S. gordonii, A. actinomycetemcomitans, F. nucleatum, P. gingivalis, and T. forsythia. Lipopolysaccharide (LPS)-induced RAW 264.7 inflammation was reduced by irradiation with 525-nm LED before LPS treatment and irradiation with 630-nm LED after LPS treatment; however, the effects were limited. CONCLUSIONS LED irradiation at 470 nm showed bactericidal effects, while LED irradiation at 525 and 630 nm showed preventive and treatment effects on LPS-induced RAW 264.7 inflammation. The application of LED irradiation has potential as an adjuvant in periodontal therapy, although further investigations should be performed in vivo.

Abstract
Subgingival air-polishing devices (SAPD) can reduce bacterial biofilms and thus support periodontal healing. The authors of this study evaluated the effectiveness of the glycine-based and trehalose-based air-polishing powders in removing pathogenic bacteria in a subgingival biofilm model. We treated 56 subgingival pockets in porcine jaws with SAPD. Subgingival air polishing was performed in three groups of 13 pockets each: I, glycine-based powder; II, trehalose-based powder; and III, water alone. Another group (IV) served as untreated controls. Prior to air polishing, inoculated titanium bars were inserted into the pockets containing periopathogenic bacteria such as Porphyromonas gingivalis and Tannerella forsythia. Remaining bacteria were evaluated using real-time PCR. The numbers of remaining bacteria depended on the treatment procedure, with the lowest number of total bacteria in group I (median: 1.96 × 106 CFU; min: 1.46 × 105; max: 9.30 × 106). Both polishing powders in groups I and II (median: 1.36 × 107 CFU; min: 5.22 × 105; max: 7.50 × 107) showed a statistically significantly lower total bacterial load in comparison to both group IV (median: 2.02 × 108 CFU; min: 5.14 × 107; max: 4.51 × 108; p < 0.05) and group III (median: 4.58 × 107 CFU; min: 2.00 × 106; max: 3.06 × 108; p < 0.05). Both subgingival air-polishing powders investigated can reduce periopathogenic bacteria and thus support antimicrobial therapy approaches in periodontal treatment regimens.

Abstract
Background Oral submucous fibrosis (OSMF) is one of the common oral potentially malignant disorders that can result in severe morbidity. Depending upon the stage of disease, multiple management therapies exist which include medicinal and surgical approaches. Although the surgical approach is preferred in severe conditions, numerous studies have reported its post-surgical deteriorating outcomes including increased fibrotic changes. To reduce these post-surgical complications, Light amplification by stimulated emission of radiation (Laser) has been introduced and studied as a non-invasive technique to treat oral submucous fibrosis. However, there exists a lack of knowledge about ‘which laser shows a better post-treatment outcome’. Accordingly, this review aims to answer this question. Materials and methods A systematic review of the published literature was performed using an electronic search in PubMed/Medline, Science Direct, Web of Science, Embase, J- STAGE, Google Scholar, and Scopus databases, from 1952 till 2019 using keywords like, ‘Oral submucous fibrosis’, ‘Treatment’, ‘Laser’, ‘Trismus’, ‘ Fibrosis’, ‘Surgical’, ‘Non-invasive’, and ‘Postoperative results’. Results The search strategy revealed 20 relevant published studies in which laser had been used to treat 250 patients of OSMF. Effective results were found without any complications in all the cases after follow up. Conclusion Observing the current literature, it can be concluded that laser might be used as a potential non-invasive approach in the management of OSMF, however, large scale studies are required to investigate the efficacy and other effects of this technology.

Abstract
Introduction: The aim of this article was to evaluate reports in the scientific literature that used antimicrobial photodynamic therapy (aPDT) with a blue light source and curcumin and riboflavin as photosensitizers in the management of periodontitis. Methods: The search was conducted in electronic databases, including PubMed, Web of Science, and Scopus, with the keywords "photodynamic therapy", "antimicrobial photodynamic therapy", "laser activated disinfection", "photoactivated disinfection", "light activated disinfection" "LED", "Periodontitis", "Curcumin", "Riboflavin", and "periodontitis" from 2012 to 2020. Results: After evaluating a total of 24 relevant articles, 13 articles were selected, full texts were read, and the data were extracted and placed in a table. Conclusion: Reviewing articles showed that curcumin as a photosensitizer activated by a blue wavelength is effective in the elimination of the various bacterial species involved in periodontal disease, and to the best of our knowledge, there is no study that has shown this substance does not reduce bacteria. According to the result of the articles, riboflavin as a photosensitizer activated by blue light can reduce bacteria that are involved in periodontitis, but other studies have reported that blue light alone can also reduce bacteria significantly. Therefore, more in-vitro and clinical trial studies are needed to give a more conclusive opinion on the effectiveness of riboflavin as a photosensitizer in the treatment of periodontitis.

Influence of antibacterial effects of tetracycline, laser, and photodynamic therapy on cell viability, cell damage, and virulence of Porphyromonas gingivalis. Photodiagnosis Photodyn Ther 2021; 36:102617. [PMID: 34740837 DOI: 10.1016/j.pdpdt.2021.102617] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 10/18/2021] [Accepted: 10/29/2021] [Indexed: 10/19/2022]
Abstract
INTRODUCTION This study compares and evaluates the efficacy of tetracycline, laser and photodynamic therapy on bacterial counts, cell damage, cell viability and neutralization of gingipains. MATERIAL AND METHODS P.gingivalis (ATCC 33,277) was cultured anaerobically. The minimal inhibitory concentration (MIC) for 50% inhibition of P.gingivalis by tetracycline, laser, and toluidine blue (TB) was determined using spectrophotometry. The antibacterial effects, cell viability, cell damage and neutralization of gingipains of the treated groups was evaluated by microbial culture and counting, 2,3 Bis 2 Methyloxy-4 Nitro-5 Sulphophenyl 2 H tetrazolium-5-Carboxaanilide (MTT) assay, lactate dehydrogenase (LDH) assay, and gingipain assay (BAPNA). RESULTS The MIC of tetracycline, toulidine, diode laser (810nmm; 0.5 Watts) is 1 µg/mL, 50 µg/mL and 15 s respectively. Comparative analysis for bacterial colony reduction was highest in tetracycline followed by PDT and then laser group at p < 0.01. MTT assay shows a significantly lesser number of viable cells in the tetracycline and PDT group when compared to laser group p < 0.01. Comparative analysis for cell damage using LDH shows the highest results for PDT followed by tetracycline and laser at p < 0.01. The highest neutralization of the gingipains is seen in the PDT group followed by tetracycline and laser groups at p < 0.01. CONCLUSION PDT shows highest antibacterial activity, gingipain neutralization, cell damage, and least number of viable cells in comparison with tetracycline and laser.

Abstract
PURPOSE This article describes a novel, minimally invasive procedure called Er:YAG laser micro-keyhole surgery (EL-MIKS) that removes metal or amalgam tattoos in the gingiva adjacent to prosthetic teeth without gingival deformity and recession. We aimed to evaluate the clinical efficacy of EL-MIKS for removing metal tattoos and present its long-term treatment outcomes. METHODS The EL-MIKS procedure consists of several steps that are all performed under a microscope. First, a micro-keyhole (1-2 mm diameter) was prepared using an Er:YAG laser in the center of the metal pigmentation. The connective tissue was evaporated in the deep layer, where metal debris was deposited. Second, within the accessible range, the irradiation angle was changed in various directions to ablate the metal pieces and discolored connective tissue without enlarging the keyhole. Finally, after blood filled the space created by the tissue evaporation, the surface of the blood clot at the entrance of the micro-keyhole was thermally coagulated with defocus laser irradiation. Pigmentation that could not be successfully removed from a single micro-keyhole was treated by forming new micro-keyholes at a distance of 3 mm or more from each previously created hole. Depigmentation over an extended area was completed over a few sessions every 4 weeks without gingival recession after surgery. CONCLUSIONS EL-MIKS, a novel depigmentation technique, was able to successfully remove an extended area of metal tattoos in the gingiva using a simpler, easier, and less invasive procedure than conventional periodontal plastic surgery. Esthetic restoration was successfully achieved without postoperative alteration of the gingival contour.

Abstract
This review aims to evaluate the adjunctive clinical effectiveness of diode laser (DL) to scaling and root planing (SRP) in the treatment of periodontitis, and identify the optimal combination of usage mode and application regimen of DL. Eight electronic databases were searched up to January 2021. Probing pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), plaque index (PI), and gingival index (GI) were assessed at short-term (4-6 weeks), 3-month, and 6-month follow-ups. Based on DL usage mode, studies were divided into three groups: inside, outside pocket, and combined modes. As for application regimen, studies in each group were further subdivided into single- and multiple-session subgroups. Thirty randomized controlled trials with 825 participants were included. For inside mode, single-session DL showed significant improvements for PPD (short-term, and 3-month, p < 0.05), CAL (short-term, and 3-month, p < 0.05), PI (3- and 6-month, p < 0.05), and GI (short-term, 3-month, and 6-month, p < 0.05). For outside mode, multiple-session DL showed notable improvements for most clinical outcomes (p < 0.05). The effect of combined mode was still uncertain. Adjunctive DL had additional clinical benefits in the treatment of periodontitis. One session laser treatment is suggested when DL is applied inside pocket in future clinical practice. Meanwhile, more than one session laser treatment presents better outcomes when DL is used outside pocket. PROSPERO: CRD42020156162.

Abstract
The present case series demonstrates the efficacy of an 810 nm diode laser for the surgical management of oral soft tissues related to orthodontic treatment. Three orthodontic patients aged 16-23 years underwent operculectomy, ablation of soft-tissue overgrowth over orthodontic appliance and gingivectomy along with gingival recontouring procedures, respectively, using the 810 nm diode laser. In each case, an initiated laser fibre tip was utilised to ablate the tissue at the treatment site by making a light contact with the tissue (average power output = 1-1.6 W, continuous wave emission mode, fibre diameter = 400 µm, spot size = 0.0013 cm2, energy density = 124.9-199.9 J/cm2, irradiance = 796-1273 W/cm2, total energy dose = 300-480 J). The maximum total length of treatment was 300 s (5 min). None of the patients reported any instantaneous or delayed postoperative complications over six months. Utilisation of the 810 nm diode laser for surgical management of oral soft tissues related to orthodontic treatments can be considered safe, effective and justifiable over the conventional scalpel technique; however, it must be performed by trained and experienced clinicians only.

Residual periodontal pocket treatment with Er:YAG laser-assisted comprehensive periodontal pocket therapy: a retrospective study. Clin Oral Investig 2021; 26:761-771. [PMID: 34278521 DOI: 10.1007/s00784-021-04054-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 06/26/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES Recently, the application of erbium-doped yttrium aluminum garnet (Er:YAG) laser has been increasing in periodontal therapy. In this retrospective study, we evaluated the safety and effectiveness of a novel pocket therapy using Er:YAG laser in combination with conventional mechanical scaling and root planing treatment (Er:YAG laser-assisted comprehensive periodontal pocket therapy). METHODS Forty sites in 29 elderly patients having residual periodontal pockets of ≥ 5 mm depth were treated by curette and Er:YAG laser from 2006 to 2009. After root debridement by curette, laser irradiation was performed on the root surfaces. Then, inflamed connective tissue on the inner gingival surface and on the bone surface/within extant bone defects was thoroughly debrided by curette and laser. Furthermore, in most cases, removal of the outer epithelium and coagulation of the blood clot in the pocket entrance were additionally performed with laser. Clinical parameters were evaluated before and 3, 6, and 12 months after treatment. RESULTS With Er:YAG laser-assisted pocket therapy, debridement of pockets was thoroughly and safely performed, and favorable clinical improvements were observed in most cases, without any adverse side effects and complications. After 1 year, probing pocket depth significantly decreased from 6.4 ± 1.4 to 3.5 ± 1.3 mm (p < 0.001, 3.0 mm reduction), and clinical attachment level significantly decreased from 7.5 ± 1.6 to 5.2 ± 1.9 mm (p < 0.001, 2.3 mm gain). CONCLUSION The results of this study indicate that Er:YAG laser-assisted therapy is useful for the treatment of residual pockets as a minimally invasive flapless surgery. CLINICAL RELEVANCE Er:YAG laser-assisted comprehensive pocket therapy reduces the necessity of more conventional surgical therapies.

J Indian Soc Periodontol 2021; 25:335-340. [PMID: 34393405 PMCID: PMC8336765 DOI: 10.4103/jisp.jisp_448_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 01/24/2021] [Accepted: 02/09/2021] [Indexed: 12/31/2022] Open
Abstract
Aim: The aim is to compare the clinical efficacy of diode laser and erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er, Cr:YSGG) laser for implant stage 2 recovery procedure. Materials and Methods: A total of 30 patients who had undergone dental implant placement were included in this study. The subjects were randomly allocated into three groups. Group 1 patients (n = 10) had implant recovery using diode laser, Group 2 (n = 10) implant recovery with Er, Cr:YSGG and conventional scalpel method (n = 10) was the third group. The pain assessment was recorded using visual analog scale (VAS scale), time taken for the procedure, intra-operative bleeding, time taken for healing were recorded for the three groups. Results: Data were tabulated and the results were analyzed using SPSS software version 26. Mann–Whitney U-test was used to compare the postoperative analgesic used, postoperative VAS score, the time taken for recovery and time taken for healing between the three study groups. Results were considered to be statistically significant when P < 0.05. Operation duration under Er, Cr:YSGG were much faster than the diode laser, however the results were not statistically significant (P = 0.051). The operation time under Er, Ch: YSGG and laser were faster than the conventional scalpel group (P = 0.000). The time taken for healing was faster in the Er, Cr:YSGG laser group than the diode laser and the scalpel group (P = 0.000). VAS scale at day 0 was higher in the conventional group than the two laser groups (P = 0.000). Conclusion: Considering the advantages of both these laser systems such as less anesthesia, less surgical trauma and faster healing, and post-operative comfort, lasers are an effective tool for implant stage two recovery techniques. However, since diode lasers are more cost effective when compared to Er, Cr:YSGG, diode lasers may meet the clinical needs when compared to hard-tissue lasers.

Abstract
BACKGROUND A pyogenic granuloma is an inflammatory exophytic lesion that can occur in the oral cavity. Numerous factors are involved in the etiology of the lesion and can lead to the tissue proliferation underlying the lesion's characteristic appearance. The main treatment is surgical excision with careful curettage of the surrounding tissues. The use of a laser has been proposed because it enables performing deep and precise incisions with better hemostasis and less invasive procedures with less discomfort to patients. The aim of this study was to evaluate the possible advantages of using a diode laser in the surgical treatment of pyogenic granuloma, particularly in the management of a pediatric patient. CASE REPORT A swelling in the lower lip of an 11-year-old female patient was analyzed. After several evaluations, a 980-nm diode laser in continuous wave mode was chosen for excision of the lesion. The lesion was excised successfully with a diode laser as a conservative method that was nonstressful for the pediatric patient. CONCLUSIONS Among the techniques for surgical excision of a lesion, the use of a diode laser has the following advantages: less invasiveness, absence of intra- and postoperative discomfort and pain, effective hemostasis with better control of bleeding, absence of scarring, better postoperative management, and greater patient compliance.

Abstract
Background Due to the limitations of scaling and root planing (SRP) in chronic periodontitis (CP) management, research has been focused on utilising additional therapies to enhance conventional treatment methods. The present systematic review is aimed to appraise the accessible scientific evidence of in vivo human studies to establish the effectiveness of adjunctive diode (λ 808- λ 980nm) laser treatment to SRP in CP. Methodology This systematic review was conducted following the PRISMA statement guidelines. The review protocol is registered in PROSPERO (CRD 42021227695). The search strategies were based on structured electronic and manual (with appropriate keywords) and were conducted to collect the applicable published data on RCTs studies (in vivo human), spanning over ten years between August 2010 and August 2020. The articles were selected to address the following research focus question: “Does diode laser (λ 808- λ 980nm) therapy have superior effects as an adjunct to SPR, compared to SRP alone, in terms of clinical or microbiological or immunological profiles in the management of CP?” Results Fifteen articles met the eligibility criteria and are included in this review. A wide range of discrepancies and inconsistencies were shown in the outcomes of the laser and SPR treatment modality, compared to SRP alone. The data on standardised study protocol, optimal laser parameters and outcome measurements were inconclusive, and a high risk of bias in the majority of the studies observed, which are crucial in establishing a homogenous and reproducible protocol. Conclusion In light of the confined evidence-based data and critical evaluation of this systematic review, the efficacy of adjunctive diode laser treatment ranging between 808 and 980nm to SRP remains debatable. The observational quality of the present systematic review was emphasised after scrutinising the available data, and an attempt to propose a laser protocol for future RCTs consideration was a great challenge due to an absence of clear and standardised recommendations in delivering a reliable laser protocol which can be replicable by future investigators. RCTs with robust methodology are warranted.

Abstract
Severe periodontitis is challenging to treat. The aim of this study was to evaluate the efficacy of a combined Er:YAG laser (ERL) and Nd:YAG laser (NDL) in non-surgical treatment for severe periodontitis. One week after supragingival scaling, 32 systemically healthy patients with stage III or IV periodontitis were randomly divided into a control group (16 subjects) and a test group (16 subjects). The control group was treated by scaling and root planning (SRP) with ultrasonic equipment and manual instruments, and the test group was treated by SRP as well as ERL and NDL. Before treatment, the following clinical parameters were recorded at baseline: debris index (DI), probing depth (PD), clinical attachment level (CAL), and percentage of bleeding on probing (BOP %). Two months after therapy, the clinical parameters were recorded again, and the results between the groups were compared. All clinical parameters were significantly improved in both groups after therapy. For moderately deep periodontal pockets (4 mm ≤ PD ≤ 6 mm), the gains in CAL were greater in the test group (1.17 ± 1.47 mm) than in the control group (0.46 ± 2.78 mm), while no significant difference was found for PD reductions after therapy between the two groups. For deep periodontal pockets (PD > 6 mm), the differences in all of the clinical parameters were similar between the test group and the control group. In this short-term study, ERL and NDL radiation exhibited potential advantages in improving the clinical attachment level compared to conventional SRP in the non-surgical treatment of severe periodontitis.
